Description

  The present invention relates to a vehicle wireless communication terminal used for remote control of a vehicle, and a wireless vehicle control system including the vehicle wireless communication terminal and a vehicle control device.

  In recent years, a keyless entry system including a vehicle control device mounted on a vehicle and a vehicle wireless communication terminal possessed by a user is often employed in an automobile which is a typical example of a vehicle. As shown in Patent Document 1, the keyless entry system is a system that automatically locks and unlocks the door of a vehicle in a hands-free manner. The key entry system also has a remote control function for controlling opening and closing of the electric door in response to an operation on an operation unit such as an “open button” and a “close button” provided in the vehicle wireless communication terminal. There are many cases.

  In a key entry system for a vehicle, the vehicle control device needs to recognize whether the vehicle wireless communication terminal exists in the vehicle, around the door of the vehicle, or in other places. Therefore, in the vehicle key entry system, the signal transmission from the vehicle control device to the vehicle wireless communication terminal is an LF (Low Frequency: about 30 KHz to 300 KHz) wave that facilitates fine adjustment of the communicable region by adjusting the electric field strength. It is often performed using. On the other hand, signal transmission from the vehicle wireless communication terminal to the vehicle control apparatus is often performed using UHF (Ultra High Frequency) waves, which are radio waves having a frequency of about 300 MHz to 3 GHz.

  That is, the vehicle control device sequentially selects a part of a plurality of transmission antennas each having a communication area in the vicinity of the door inside and outside the vehicle, and wirelessly transmits the vehicle through the selected transmission antenna. LF wave signals are sequentially transmitted to the communication terminal. In addition, the vehicle control device receives a UHF wave signal through the reception antenna as a response from the vehicle wireless communication terminal. The vehicular control device is configured so that the vehicular radio communication terminal is installed in the vehicle or outside the vehicle in accordance with the establishment status of the communication when the communication with the vehicular radio communication terminal is performed and the selection status of the transmission antenna. It is determined whether it exists in the vicinity of the door and other places (places where the LF wave does not reach).

  For example, in Patent Document 1, an ECU (Electric Control Unit) sequentially selects a part of a plurality of transmission antennas each having an inner side and an outer side of a vehicle as communication areas individually, and the vehicle is transmitted through the selected transmission antennas. It shows the transmission of a signal to a wireless communication terminal. Patent Document 1 also shows that a transmission antenna selected from a plurality of transmission antennas is driven by one LF (Low Frequency) driving circuit provided in common to the plurality of transmission antennas. Has been. The LF drive circuit is a circuit that supplies a drive signal having a frequency of about 30 KHz to 300 KHz to the antenna in order to output a low-frequency radio wave.

  By the way, if the vehicle wireless communication terminal is used for both the remote control of the vehicle and the remote control of devices other than the vehicle related to the vehicle, there is no need for the user to possess a plurality of wireless terminals. high. For example, a vehicular wireless communication terminal is also used for remote control of a device that drives a gate of a parking lot (including a garage) or remote control of a device that drives an elevating wheel stopper provided in the parking lot. Is preferable.

  For example, Patent Document 2 discloses that a vehicle wireless communication terminal is used for both remote control for locking and unlocking a door of a vehicle and remote control for locking and unlocking a door of a house. It is shown. Japanese Patent Application Laid-Open No. 2004-259542 discloses a configuration for a vehicle wireless communication terminal to select which of a vehicle control signal and a house control signal is transmitted in response to an operation on an operation switch (operation unit). As examples, a plurality of examples are shown. The first example is an example in which the vehicle wireless communication terminal individually includes an operation switch corresponding to a vehicle control signal and an operation switch corresponding to a house control signal. A 2nd example is an example in which the radio | wireless communication terminal for vehicles is equipped with the operation switch corresponding to the content of control (locking or unlocking), and the operation switch for selecting the use for vehicles and a house separately. is there.

The operation button 11 is an example of an operation unit that is operated for remote control of the vehicle 9. The memory 17 is, for example, a flash memory or an EEPROM (Electrically Erasable Programmable ROM).

  The transmission circuit 13 in the wireless terminal 10 is a circuit that transmits a wireless signal to an external device. Here, external devices that are counterparts of wireless transmission by the transmission circuit 13 include an ECU 20 mounted on the vehicle 9 and a garage gate drive device 30 that is an example of a device other than the vehicle 9. The transmission circuit 13 in the wireless terminal 10 uses UHF waves as signal transmission radio waves. That is, the transmission circuit 13 generates an antenna drive signal that is modulated according to the transmission signal of the terminal control circuit 12 with respect to a reference signal (carrier wave) having a frequency of about 300 MHz to 3 GHz, and uses the antenna drive signal as a terminal. This is a circuit to be supplied to the transmitting antenna 14 on the side.

  The receiving circuit 15 in the wireless terminal 10 is a circuit that receives a wireless signal transmitted from the vehicle 9 through the receiving antenna 16 on the terminal side. The reception circuit 15 in the wireless terminal 10 uses LF waves as signal transmission radio waves. That is, the reception circuit 15 extracts a received signal by removing a carrier component of about 30 KHz to 300 KHz from a signal input through the receiving antenna 16 on the terminal side, and outputs the received signal to the terminal control circuit 12. It is.

  The terminal control circuit 12 transmits a control signal (transmission signal) corresponding to an operation on the operation button 11 to the outside through the transmission circuit 13 and a process according to the content of the reception signal input through the reception circuit 15.

  For example, the terminal control circuit 12 detects an operation on the operation button 11 and supplies a control signal (transmission signal) corresponding to the detected operation to the transmission circuit 13, thereby outputting the control signal to the outside through the transmission circuit 13. . Further, as control signals transmitted in response to an operation on the operation button 11, there are a vehicle control signal for remote control of the vehicle 9 and a garage control signal for remote control of the garage gate drive device 30. .

  When the operation on the operation button 11 is detected, the terminal control circuit 12 selects one of the vehicle control signal and the garage control signal and sends it out. For example, when the operation of the “open button” in the operation button 11 is detected, the terminal control circuit 12 controls the vehicle control signal for requesting the unlocking of the door lock device in the vehicle 9 or the garage gate 40 depending on the situation. Send out a garage control signal requesting to open.

Send out a garage control signal requesting closing. Details of the control signal selection method will be described later.

  The terminal control circuit 12 also performs processing for transmitting an ID code, which is identification information unique to each vehicle 9, to the outside through the transmission circuit 13. The ID code is recorded in advance in a memory provided in the wireless terminal 10, for example, the memory 17. When the terminal control circuit 12 receives a control signal requesting an ID code from the ECU 20 through the receiving circuit 15, the terminal control circuit 12 transmits the ID code as a response process. The terminal control circuit 12 also transmits an ID code together with the control signal when transmitting the vehicle control signal or the garage control signal.

The terminal position information is information for identifying whether the wireless terminal 10 exists in the vehicle 9 (inside the vehicle) or outside the vehicle 9. Details of processing related to acquisition of terminal position information will be described later.

<ECU 20>
As shown in FIG. 1, the ECU 20 mounted on the vehicle 9 includes a reception circuit 21, a transmission circuit 22, a vehicle control circuit 23, and a nonvolatile rewritable memory 24. The memory 17 is, for example, a flash memory or an EEPROM (Electrically Erasable Programmable ROM).

  The vehicle 9 on which the ECU 20 is mounted is provided with a plurality of transmission antennas 8, a reception antenna 6, a plurality of detection switches 5, a vehicle speed detector 4, a door lock motor 3 that drives the door of the vehicle 9, and the like. . The detection switch 5 is, for example, a door switch that detects whether each of a plurality of doors included in the vehicle 9 is open or closed, and a push button type operation switch for starting the engine of the vehicle 9. A start switch and the like are included.

  The reception circuit 21 of the ECU 20 is a circuit that wirelessly receives a signal transmitted from the wireless terminal 10 through the reception antenna 6. That is, the receiving circuit 21 of the vehicle 9 extracts a received signal by removing a component of a carrier wave (UHF wave) of about 300 MHz to 3 GHz from a signal input through the receiving antenna 6 of the vehicle 9, and the received signal is extracted from the vehicle. It is a circuit that outputs to the control circuit 23.

  The transmission circuit 22 of the ECU 20 is a circuit that wirelessly transmits a signal to the wireless terminal 10 through a part of the transmission antennas 8 selected from the plurality of transmission antennas 8 by the vehicle control circuit 23. The transmission circuit 22 in the ECU 20 uses LF waves as signal transmission radio waves. That is, the transmission circuit 22 generates an antenna drive signal in which a reference signal (carrier wave) having a frequency of about 30 KHz to 300 KHz is modulated according to the transmission signal of the vehicle control circuit 23, and the antenna drive signal is transmitted to the vehicle. 9 is a circuit that supplies power to 9 transmitting antennas 8.

  The vehicle control circuit 23 performs control corresponding to the vehicle control signal when the reception circuit 21 receives a vehicle control signal for remote control of the vehicle 9. For example, when a vehicle control signal requesting unlocking of the door lock device of the vehicle 9 is received, the vehicle control circuit 23 controls the power supply to the door lock motor 3 so that the door lock device is in the unlocked state. Then, the door lock motor 3 is driven. Further, when a vehicle control signal requesting locking of the door lock device of the vehicle 9 is received, the vehicle control circuit 23 controls the power supply to the door lock motor 3 so that the door lock device is locked. The door lock motor 3 is driven.

  Further, the vehicle control circuit 23 has a function of selecting a part of the plurality of transmission antennas 8 as a transmission destination of the signal by the transmission circuit 22. For example, as shown in FIG. 1, the ECU 20 may include a plurality of switches 25 corresponding to each of the plurality of transmission antennas 8. In this case, the vehicle control circuit 23 performs an antenna selection process for selecting a part of the plurality of transmission antennas 8 by individually outputting a control signal to each of the plurality of switches 25. The plurality of switches 25 are, for example, FETs. Each switch 25 switches the signal transmission line of the corresponding transmitting antenna 8 to a connected state or a blocked state in accordance with an input control signal (ON signal / OFF signal). Thereby, the antenna drive signal output from the transmission circuit 22 is supplied only to the transmission antenna 8 corresponding to the switch 25 in the connected state. In some cases, the switch 25 is not provided, and the vehicle control circuit 23 includes a plurality of signal output ports corresponding to each of the plurality of transmission antennas 8. In this case, the vehicle control circuit 23 executes antenna selection processing by software processing that selects a signal output port that outputs an antenna drive signal through the transmission circuit 22.

  As shown in FIG. 2, the plurality of transmission antennas 8 include a plurality of outer antennas 8 </ b> A whose main communication area is a communication area 81 </ b> A around the door outside the vehicle 9, and the inside (room) of the vehicle 9. Including one or a plurality of inner antennas 8B serving as a main communication area 81B. As described above, the plurality of transmission antennas 8 are antennas in which the outside and the inside of the vehicle 9 are individually set as the communication areas 81 (81A and 81B).

  Further, the vehicle control circuit 23 receives the ID code from the wireless terminal 10 through the receiving circuit 21, and whether or not the received ID code matches an ID code recorded in advance in a memory (for example, the memory 24) provided in the ECU 20. ID code collation processing is performed to determine whether or not. The vehicle control circuit 23 receives the control signal corresponding to the ID code only when the verification of the ID code is successful, that is, only when the received ID code matches the pre-recorded ID code. The control according to is executed.

  Further, the vehicle control circuit 23 executes a terminal position determination process for determining whether the wireless terminal 10 exists in the vicinity of the door inside the vehicle, outside the vehicle, or in other places outside the vehicle. Here, successful verification of the ID code means that communication with the wireless terminal 10 has been established. Details of the terminal position determination process will be described later.

  The vehicle control circuit 23 also executes a process of transmitting terminal position information representing the determination result of the terminal position determination process to the wireless terminal 10 through the transmission circuit 22.

<Garage gate drive device 30>
The garage gate drive device 30 is an example of a device that controls the entry and exit of the vehicle 9 with respect to the parking lot, and as shown in FIG. Controls the opening and closing of the gate 40.

  As shown in FIG. 1, the garage gate driving device 30 includes a receiving antenna 31, a receiving circuit 32, an operation button 33, a gate motor 34, a garage control circuit 35, and the like. The operation buttons 33 are an “open button” operated to open the electric gate 40 in the garage gate driving device 30, a “close button” operated to close the electric gate 40, and the electric gate 40. Including a “stop button” operated to stop the operation. The gate motor 34 is a motor that drives the gate 40 of the garage.

  The receiving antenna 31 and the receiving circuit 32 in the garage gate driving device 30 are components equivalent to the receiving antenna 6 and the receiving circuit 21 in the vehicle 9, respectively. That is, the receiving circuit 32 of the garage gate driving device 30 removes the carrier wave (UHF wave) component from the signal input through the receiving antenna 31 and extracts the received signal, and outputs the received signal to the garage control circuit 35. Circuit.

  When the garage control circuit 35 receives a garage control signal for remote control of the garage gate driving device 30 by the receiving circuit 32, the garage control circuit 35 performs control corresponding to the garage control signal. For example, when a garage control signal requesting to open the garage gate 40 is received, the garage control circuit 35 controls the power supply to the gate motor 34 to drive the gate motor 34 so that the gate 40 is opened. Let Further, when a garage control signal requesting that the gate 40 be closed is received, the garage control circuit 35 controls the power supply to the gate motor 34 to drive the gate motor 34 so that the gate 40 is closed.

  Further, the garage control circuit 35 detects an operation on the operation button 33 and performs control corresponding to the operated operation button 33. That is, the garage control circuit 35 controls the power supply to the gate motor 34 when each operation of the “open button”, “close button”, and “stop button” on the operation button 33 is detected, thereby the gate 40. Controls the opening, closing and stopping operations.

  The garage control circuit 35 receives the ID code from the wireless terminal 10 through the receiving circuit 32 and determines whether or not the received ID code matches the ID code recorded in advance in the memory of the garage control circuit 35. ID code verification processing is performed. The garage control circuit 35 receives the control signal corresponding to the ID code only when the verification of the ID code is successful, that is, only when the received ID code matches the pre-recorded ID code. The control according to is executed.

<Terminal position determination process>
Next, an example of the terminal position determination process executed in the wireless vehicle control system 1 will be described with reference to the flowchart shown in FIG. In addition, S11 to S76 shown below are identification codes of procedures executed by the terminal control circuit 12, the vehicle control circuit 23, or the garage control circuit 35.

  In the terminal position determination process, first, the vehicle control circuit 23 of the ECU 20 monitors whether or not a transmission start event serving as a trigger for starting signal transmission to the wireless terminal 10 has occurred (S11). The transmission start event may be, for example, that the request switch attached to the door of the vehicle 9 has been pressed or that the touch sensor has been touched, that the door in the vehicle 9 has been opened or closed, or that the user has been seated. Detected, that the engine start operation has been performed, the speed of the vehicle 9 has exceeded or dropped below a preset speed, a predetermined control signal has been received through the receiving circuit 21, etc. It is.

  An operation for opening and closing the door of the vehicle 9 is detected by a door switch in the detection switch 5, and an operation for starting the engine is detected by an engine start switch in the detection switch 5. The detection switch 5 includes a request switch of the vehicle 9, a touch sensor, a seating sensor, and the like. The speed of the vehicle 9 is detected by the vehicle speed detector 4.

  When the vehicle control circuit 23 detects that a transmission start event has occurred, the vehicle control circuit 23 receives a response request signal for the wireless terminal 10 through the transmission circuit 22 and a response signal from the wireless terminal 10 through the reception circuit 21. The process is executed (S12). At that time, the vehicle control circuit 23 transmits a response request signal through the selected transmission antenna 8 while sequentially switching the selection status of the transmission antenna 8. The vehicle control circuit 23 that executes the process of step S12 is an example of an antenna selection unit.

  Moreover, the vehicle control circuit 23 includes an antenna code for identifying the transmission antenna 8 used for transmitting the response request signal in the response request signal. The response signal includes an ID code and an antenna code. Thereby, the vehicle control circuit 23 can grasp | ascertain the correspondence of the selection condition of the transmission antenna 8 when a response request signal is transmitted, and a response signal. In the following cases, it may be possible not to include the antenna code in the response request signal. For example, when the switching cycle of selection of the transmission antenna 8 is sufficiently long with respect to the time required for receiving the response signal, the transmission antenna 8 that has transmitted the response signal can be distinguished. In addition, even when the transmission timing of the response signal by each transmission antenna 8 after the response request signal is transmitted is determined in advance, the transmission antenna 8 can be distinguished by the reception timing of the response signal. In these cases, it may be considered that the antenna code is not included in the response request signal.

  Then, when the response signal can be received, the vehicle control circuit 23 shifts the process to the next step S14 (S13). On the other hand, if the response signal corresponding to the vehicle control circuit 23 cannot be received within a predetermined time after transmitting the response request signal in the process of step S12, the vehicle control circuit 23 shifts the process to step S17 described later (S13).

  Next, the vehicle control circuit 23 performs an ID code collation process for collating the ID code received in step S13 with the ID code stored in advance by the ECU 20 (S14). Then, when the two ID codes do not match, that is, when the regular communication with the wireless terminal 10 is not established, the vehicle control circuit 23 returns the process to step S11 described above (S15).

  On the other hand, when the two ID codes match, that is, when normal communication with the wireless terminal 10 is established, the vehicle control circuit 23 performs processing corresponding to the transmission start event detected in step S11 as necessary. Is executed (S16).

  For example, when the transmission start event detected in step S11 is an engine start operation, the vehicle control circuit 23 executes a process for starting the engine. Note that if the transmission start event detected in step S11 is an event for which no corresponding process is defined, such as an operation of opening and closing the door of the vehicle 9, the process of step S15 is skipped.

  Next, the vehicle control circuit 23 executes a terminal position determination process and records terminal position information as a result of the process in the memory 24 (S17). The terminal position determination process includes the ID code request and reception performed through the transmission circuit 22 and the reception circuit 21 (S12), and the communication establishment status when the communication is performed (ID code verification process (S14)). This is a process of determining whether the wireless terminal 10 exists in the vicinity of the door inside the vehicle, outside the vehicle, or in other places outside the vehicle according to the result.

  As an example of a process for determining whether the wireless terminal 10 exists in the vicinity of the door inside the vehicle, outside the vehicle, or in other places outside the vehicle, the vehicle control circuit 23 has successfully verified the ID code (S14). The position of the wireless terminal 10 is determined based on the antenna code included in the response signal together with the ID code. Hereinafter, the antenna code is referred to as a reception antenna code. The vehicle control circuit 23 determines that the wireless terminal 10 is present in the vehicle when the reception antenna code is an antenna code corresponding to the inner antenna 8B (S17). Further, when the reception antenna code is an antenna code corresponding to the outer antenna 8A, the vehicle control circuit 23 determines that the wireless terminal 10 is present around the door outside the vehicle, that is, in the communication area 81A of the outer antenna 8A. (S17).

  If the vehicle control circuit 23 fails to receive a response signal in response to the transmission of the response request signal in step S12, the wireless terminal 10 is located outside the vicinity of the door outside the vehicle, that is, outside antenna 8A outside the vehicle. It is determined that it exists in a place other than the communication area 81A (S17). The vehicle control circuit 23 that executes the process of step S17 is an example of a terminal position determination unit.

  Next, the vehicle control circuit 23 transmits terminal position information corresponding to the determination result in step S17 to the wireless terminal 10 through the transmission circuit 22 (S18). Here, the terminal location information transmitted to the wireless terminal 10 may be information indicating at least whether the wireless terminal 10 exists inside or outside the vehicle. For example, in step S17, when it is determined that the wireless terminal 10 exists in the vicinity of the door outside the vehicle or elsewhere, the terminal position information is information in which the determination results are aggregated, that is, simply outside the vehicle. It may be information indicating that it exists. The vehicle control circuit 23 that executes the process of step S18 is an example of a position information sending unit. In addition, the vehicle control circuit 23 returns a process to step S11 mentioned above after execution of the process of step S18.

  On the other hand, in the terminal position determination process, the terminal control circuit 12 in the wireless terminal 10 first monitors whether or not the response request signal transmitted from the vehicle control circuit 23 in step S12 is received through the receiving circuit 15 ( S21).

  Then, when the response request signal is received, the terminal control circuit 12 transmits a response signal including the antenna code included in the response request signal and the ID code stored in the memory in advance through the transmission circuit 13 ( S22).

  Further, the terminal control circuit 12 receives the terminal position information transmitted from the vehicle control circuit 23 by the process of step S18 in response to the transmission of the response signal through the receiving circuit 15, and records the received terminal position information in the memory 17. (S23). The terminal control circuit 12 returns the process to step S21 described above after the execution of the process of step S23.

  By performing the terminal position determination process shown in FIG. 3, it is determined at any time whether the wireless terminal 10 exists inside the vehicle or outside the vehicle (S17), and the terminal position information that is the determination result is the ECU 20 It is recorded in the wireless terminal 10 (S17, S23).

<Remote control>
Next, an example of a remote control procedure executed by the wireless vehicle control system 1 will be described with reference to the flowchart shown in FIG.

  In the remote control process, first, the terminal control circuit 12 of the wireless terminal 10 monitors whether or not an operation on the operation button 11 has been performed (S31).

  When the terminal control circuit 12 detects an operation on the operation button 11, the terminal control circuit 12 refers to the terminal position information recorded in advance in the memory 17 by the process of step S23 (S32). Further, the terminal control circuit 12 selects one of the vehicle control signal and the garage control signal corresponding to the operated operation button 11 according to the content of the terminal position information recorded in the memory 17, The selected control signal is transmitted to the outside through the transmission circuit 13 (S32 to S34).

  More specifically, when the terminal position information recorded in the memory 17 indicates that the wireless terminal 10 exists outside the vehicle, the terminal control circuit 12 indicates that the vehicle corresponding to the operation button 11 whose operation has been detected. Control signal is transmitted (S33). On the other hand, when the terminal position information recorded in the memory 17 indicates that the wireless terminal 10 is present in the vehicle, the terminal control circuit 12 outputs a garage control signal corresponding to the operation button 11 in which the operation is detected. Transmit (S34).

  Further, the terminal control circuit 12 includes an ID code recorded in advance in the wireless terminal 10 in the control signal transmitted in steps S33 and S34.

  And the terminal control circuit 12 returns a process to step S31 mentioned above after completion | finish of the process of step S32-S34. The terminal control circuit 12 that executes the processes of steps S32 to S34 is an example of a signal selection unit.

  On the other hand, in the remote control process, the vehicle control circuit 23 of the ECU 20 first monitors whether or not the vehicle control signal transmitted from the terminal control circuit 12 in step S33 is received through the reception circuit 21 (S41). ).

  Then, when the reception of the vehicle control signal is detected, the vehicle control circuit 23 is based on the ID code included in the vehicle control signal and the ID code stored in advance by the ECU 20 in the same manner as the process of step S14. ID code collation processing is performed (S42). Then, when the two ID codes do not match, that is, when the regular communication with the wireless terminal 10 is not established, the vehicle control circuit 23 returns the process to step S41 described above (S43).

  On the other hand, when the two ID codes match, that is, when regular communication with the wireless terminal 10 is established, the vehicle control circuit 23 executes processing corresponding to the control signal received in step S41 (S44). For example, the vehicle control circuit 23 controls the drive of the door lock motor 3 in response to an unlocking / locking request of the door lock device indicated by the vehicle control signal. Thereafter, the vehicle control circuit 23 returns the process to step S41 described above.

  In the remote control process, the garage control circuit 35 of the garage gate driving device 30 first determines whether or not the garage control signal transmitted from the terminal control circuit 12 in step S34 is received through the receiving circuit 32. Monitor (S51).

  Then, when the reception of the garage control signal is detected, the garage control circuit 35 performs step S14 based on the ID code included in the garage control signal and the ID code stored in the garage gate driving device 30 in advance. The ID code matching process is performed in the same manner as the process (S52). When the two ID codes do not match, that is, when normal communication with the wireless terminal 10 is not established, the garage control circuit 35 returns the process to the above-described step S51 (S53).

  On the other hand, when the two ID codes match, that is, when regular communication with the wireless terminal 10 is established, the garage control circuit 35 executes processing corresponding to the control signal received in step S51 (S54). For example, the garage control circuit 35 controls the driving of the gate motor 34 in response to a request for opening or closing the gate 40 of the garage indicated by the garage control signal. Thereafter, the garage control circuit 35 returns the process to step S51 described above.

  In the wireless vehicle control system 1 described above, the wireless terminal 10 is used for both remote control of the vehicle 9 and remote control of the garage gate driving device 30. Further, when the operation on the operation button 11 is detected, the wireless terminal 10 automatically recognizes whether the wireless terminal 10 exists inside the vehicle or outside the vehicle (S17, S23), and the recognition result. Accordingly, the target of remote control (the vehicle 9 or the garage gate driving device 30) is automatically switched (S32 to S34).

  Therefore, according to the wireless vehicle control system 1, the wireless terminal 10 does not require any operation switches other than the operation buttons 11 necessary for remote control of the vehicle 9, and the object of remote control is the vehicle 9. There is no need to perform different operations depending on whether the garage gate driving device 30 is used.

  That is, when the user carrying the wireless terminal 10 is outside the vehicle, the wireless terminal 10 automatically outputs a vehicle control signal in response to an operation on the operation button 11. This prevents the garage gate 40 from being unnecessarily opened and closed before the user gets on the vehicle 9, that is, in a situation where the vehicle 9 does not enter or leave the parking lot (garage). Before the user gets on the vehicle 9, the garage gate 40 is controlled in accordance with an operation on the operation button 33 of the garage gate driving device 30.

  On the other hand, when a user carrying the wireless terminal 10 is present in the vehicle, the wireless terminal 10 automatically outputs a garage control signal in response to an operation on the operation button 11. Thereby, when the user gets on the vehicle 9, that is, in a situation where the vehicle 9 enters and exits the parking lot (garage), the radio terminal 10 remotely controls the garage gate driving device 30. Function as a terminal. At that time, the user may perform the same operation as the operation for remote control of the door of the vehicle 9 as the operation for remote control of the garage gate driving device 30, and the operability is good.

Second Embodiment
Next, the wireless vehicle control system 2 according to the second embodiment of the present invention will be described. Compared with the wireless vehicle control system 1 shown in FIG. 1, the wireless vehicle control system 2 has a configuration in which some components are omitted, and is not shown. That is, the wireless vehicle control system 2 has a configuration in which only the memory 17 of the wireless terminal 10 is removed from the configuration of the wireless vehicle control system 1 shown in FIG. Hereinafter, only different points in the wireless vehicle control system 2 from the wireless vehicle control system 1 will be described.

<Terminal position determination process>
First, an example of the terminal position determination process executed in the wireless vehicle control system 2 will be described with reference to the flowchart shown in FIG. The terminal position determination process shown in FIG. 5 includes a process (S18) in which the vehicle control circuit 23 transmits terminal position information to the terminal control circuit 12 from the terminal position determination process shown in FIG. This is a process excluding the process of receiving and recording terminal location information (S23). Therefore, in the wireless vehicle control system 2, the terminal position information is not recorded in the wireless terminal 10.

<Remote control>
Next, an example of a remote control procedure executed by the wireless vehicle control system 2 will be described with reference to the flowchart shown in FIG.

  In the remote control process in the wireless vehicle control system 2, the terminal control circuit 12 of the wireless terminal 10 monitors whether or not an operation on the operation button 11 has been performed (S61).

  When the terminal control circuit 12 detects an operation on the operation button 11, the terminal control circuit 12 transmits a first vehicle control signal for requesting terminal position information to the ECU 20 through the transmission circuit 13 (S62). The first vehicle control signal includes an ID code recorded in the wireless terminal 10. The terminal control circuit 12 that executes the process of step S62 is an example of a location information request unit.

  Further, the terminal control circuit 12 monitors the terminal position information returned from the vehicle control circuit 23 in response to the transmission of the first vehicle control signal through the receiving circuit 15 (S63). If the signal is received within a certain time, the terminal control circuit 12 performs the process of step S64. On the other hand, if no signal is received within a certain time, the terminal control circuit 12 considers that the wireless terminal 10 is outside and performs the process of step S65. These processes in steps S62 and S63 are processes executed instead of the process in step S23 in the wireless vehicle control system 1. In addition, the terminal control circuit 12 which performs each process of step S62 and S63 is an example of a position information request | requirement part and a position information acquisition part.

  And the terminal control circuit 12 performs the transmission process of the control signal according to the content of terminal position information similarly to the process of steps S32-S34 in the wireless vehicle control system 1 based on the terminal position information obtained at step S63. Execute (S64 to S66). Here, the terminal control circuit 12 includes an ID code recorded in advance in the wireless terminal 10 in the control signal transmitted in steps S65 and S66. For convenience, in FIG. 6, the description of the second vehicle control signal (S65) means a vehicle control signal corresponding to the operation button 11 whose operation is detected in step S61.

  The terminal control circuit 12 returns the processing to step S61 described above after the processing of steps S64 to S66. The terminal control circuit 12 that executes the processes of steps S64 to S66 is an example of a signal selection unit.

  On the other hand, in the remote control processing in the wireless vehicle control system 2, the vehicle control circuit 23 of the ECU 20 first receives the vehicle control signal transmitted from the terminal control circuit 12 in step S62 or step S65 through the reception circuit 21. It is monitored whether or not (S71).

  When the reception of the vehicle control signal is detected, the vehicle control circuit 23 performs steps S14 and S42 based on the ID code included in the vehicle control signal and the ID code stored in advance by the ECU 20. Similarly, ID code collation processing is performed (S72). Then, when the two ID codes do not match, that is, when the regular communication with the wireless terminal 10 is not established, the vehicle control circuit 23 returns the process to step S71 described above (S73).

  On the other hand, when the two ID codes match, that is, when the regular communication with the wireless terminal 10 is established, the vehicle control circuit 23 receives the control signal received in step S71 from the first vehicle that requests the terminal position information. It is determined whether the control signal is a control signal for the vehicle or a control signal for the second vehicle corresponding to the operation button 11 (S74).

  And when the received control signal is a control signal for 1st vehicles, the vehicle control circuit 23 is the terminal recorded on the memory 24 of ECU20 by the process of FIG.5 S17 according to the request | requirement of the terminal control circuit 12 The position information is transmitted to the wireless terminal 10 through the transmission circuit 22 (S75). The vehicle control circuit 23 that executes the process of step S75 is an example of a position information sending unit. In addition, the vehicle control circuit 23 returns a process to step S71 mentioned above after the process of step S75.

  On the other hand, when the received control signal is a second vehicle control signal, that is, a vehicle control signal corresponding to the operation button 11 of the wireless terminal 10, the vehicle control circuit 23 corresponds to the second vehicle control signal. The process is executed (S76). For example, the vehicle control circuit 23 controls the drive of the door lock motor 3 in response to an unlock request or a lock request of the door lock device indicated by the second vehicle control signal. Thereafter, the vehicle control circuit 23 returns the process to step S71 described above.

  In the remote control process, the garage control circuit 35 of the garage gate driving device 30 first determines whether or not the garage control signal transmitted from the terminal control circuit 12 in step S66 is received through the receiving circuit 32. Monitor (S51).

  Then, when the reception of the garage control signal is detected, the garage control circuit 35 performs step S14 based on the ID code included in the garage control signal and the ID code stored in the garage gate driving device 30 in advance. The ID code matching process is performed in the same manner as the process (S52). When the two ID codes do not match, that is, when normal communication with the wireless terminal 10 is not established, the garage control circuit 35 returns the process to the above-described step S51 (S53).

  Also in the wireless vehicle control system 2, the garage control circuit 35 executes the same processing (S51 to S54) as the processing of the garage control circuit 35 in the wireless vehicle control system 1.

  Also in the wireless vehicle control system 2 described above, the wireless terminal 10 is used for both the remote control of the vehicle 9 and the remote control of the garage gate driving device 30. Further, when an operation on the operation button 11 is detected, the wireless terminal 10 automatically recognizes whether the wireless terminal 10 exists inside the vehicle or outside the vehicle (S17, S63), and the recognition result. Accordingly, the remote control target (vehicle 9 or garage gate drive device 30) is automatically switched (S64 to S66).

  Therefore, even when the wireless vehicle control system 2 is adopted, the wireless terminal 10 does not require the addition of operation switches other than the operation buttons 11 necessary for remote control of the vehicle 9, and the object of remote control is the vehicle There is no need to perform a different operation depending on whether it is 9 or the garage gate drive device 30.

  The embodiment described above is an example in which the device other than the vehicle 9 to be remotely controlled by the wireless terminal 10 is the garage gate driving device 30 that drives the gate 40 of the parking lot (garage). However, the device other than the vehicle 9 to be remotely controlled by the wireless terminal 10 may be another device that controls the entry / exit of the vehicle with respect to the parking lot.

  For example, a device other than the vehicle 9 to be remotely controlled by the wireless terminal 10 is a device that drives an elevating wheel stop provided in a parking lot. Such a device is widely used in coin-type parking. In this case, the terminal control circuit 12 of the wireless terminal 10 transmits a control signal for raising or lowering the liftable wheel stopper as a control signal (non-vehicle control signal) other than the vehicle control signal.
