Description

  The present invention relates to an opening / closing control device for a vehicle door.

In hatchback and one-box type vehicles, a technology has been proposed in which a tailgate (also referred to as a back door) provided on the rear side of the vehicle body can be automatically opened and closed using a drive source such as a motor. Then, it has already been put into practical use (for example, Patent Document 1).
In the opening / closing control device described in Patent Document 1, when a back door opening signal is input, the distance to the obstacle behind the vehicle is read by a back sonar (detection means) provided at the rear of the vehicle. Based on the above, the controller determines whether there is an obstacle within the movable range of the back door, and if it is determined that the back door does not collide with the obstacle, the opening operation of the back door is performed. .

  In recent years, communication between a portable device owned by a driver and a vehicle has been performed, so that a mechanical key (key) is not used and the portable device is not manually operated, and the door is locked / opened. Various systems have been proposed that enable a lock, engine start, and the like, and some systems are also applied to tailgates that automatically open and close. In such a technique, the driving force of the motor is transmitted to the tailgate via the link mechanism. For example, a driver possessing a portable device operates a switch provided on the tailgate or the like. The tailgate is released and the motor is operated so that the tailgate is automatically opened and closed.

Japanese Patent No. 4230235

However, in the opening / closing control device described in Patent Document 1, when a door opening signal is input from a handle switch provided on the back door, the back door is opened regardless of the detected value of the back sonar. Yes. For this reason, the user who operates the handle switch exists within the movable range of the back door, and the user may come into contact with the back door. (This is because it is assumed that the user is checking the presence or absence of an obstacle behind the vehicle.)
Therefore, for example, a timer is provided so that the tailgate opening or closing operation is started after a predetermined time (for example, 2 seconds) has elapsed after the user operates a switch provided on the tailgate. It can also be configured. However, for elderly people and people using wheelchairs, etc. who can not get out of the movable range of the tailgate within a preset time, the possibility of contact with the tailgate is reliably eliminated. I can't. In addition, if the predetermined time is set long in order to reliably avoid contact with the tailgate, the operation of the tailgate is not easily started even if the switch is operated, and convenience is deteriorated.

Such a problem can occur not only in a tailgate but also in a vehicle door that operates automatically.
The present invention has been devised in view of such problems, and an object thereof is to provide a vehicle door opening / closing control device that can reliably avoid contact with a vehicle door.

When the operation switch 3 is operated from outside the passenger compartment, the tailgate 5 does not operate unless the user has the portable device 2. The operation switch 3 is, for example, an on / off switch such as a push button type or a touch sensor type. The operation switch 3 is also provided on the console panel in the vehicle interior and can be operated from the vehicle interior by the user.

  The portable device 2 includes a reception unit 25 having a reception antenna 25a, a transmission unit 24 having a transmission antenna 24a, and a control unit 20. The portable device 2 wirelessly communicates with the transmission unit 14 and the reception unit 15 provided in the vehicle 1 so that a legitimate user can lock / unlock the door of the vehicle 1 and start the engine. It has become. That is, a portable device code (portable device ID) unique to the portable device set in advance in the portable device 2 and a vehicle code set in advance in an electronic control unit (hereinafter referred to as ECU) 10 mounted on the vehicle. Only when (vehicle ID) matches, the door of the vehicle 1 can be locked / unlocked, the engine can be started, and the like.

  A transmission unit (hereinafter referred to as a vehicle-side transmission unit) 14 provided in the vehicle 1 has a transmission antenna 14a. Here, the transmission antenna 14a is attached to the rear bumper 7, and when the operation switch 3 is operated from outside the passenger compartment, an ID confirmation signal (confirmation) is entered in a certain area 5A indicated by a two-dot chain line in FIG. Signal). This ID confirmation signal includes a vehicle ID preset in the ECU 10. When the portable device 2 exists in the area 5A, the ID confirmation signal is received by the receiving unit 25 of the portable device 2 via the reception antenna 25a, and the portable device 2 does not exist in the area 5A (that is, the area 5A). If it is outside) it will not be received. The mounting position of the transmission antenna 14 a is not limited to the rear bumper 7, and may be a vehicle body that is not the tailgate 5 and in the vicinity of the tailgate 5.

  The ID confirmation signal received by the receiving unit 25 of the portable device 2 is received by the ID verification unit 21 which is a functional element provided in the control unit 20 of the portable device 2. ID collation is performed. When the ID verification between the vehicle ID and the portable device ID by the ID verification unit 21 matches, an ID response signal (response signal) is transmitted from the transmission unit 24 of the portable device 2 via the transmission antenna 24a. On the other hand, when the vehicle ID and the portable device ID do not match, the ID response signal is not transmitted from the transmission unit 24.

  A receiving unit (hereinafter referred to as a vehicle-side receiving unit) 15 provided in the vehicle 1 includes a receiving antenna 15a. Here, the reception antenna 15 a is attached to the front bumper 6 and receives an ID response signal transmitted from the transmission unit 24 of the portable device 2. When an ID response signal is received by the vehicle-side receiving unit 15, the ECU 10 locks / unlocks all the doors of the vehicle 1 including the tailgate 5. That is, only when the portable device 2 is in the area 5A when the operation switch 3 is operated and the vehicle ID matches the portable device ID, all the doors of the vehicle 1 are locked / unlocked. The mounting position of the receiving antenna 15a is not limited to the front bumper 6 and may be a vehicle body that is not the tailgate 5.

  An area 5A shown in FIG. 2 is a range in which a signal is transmitted from the transmission antenna 14a on the vehicle side, and here, a range that passes when the tailgate 5 is opened and closed (that is, a movable range of the tailgate) Thus, the transmission power of the signal is set in advance. In FIG. 2, a substantially rectangular area 5A is provided behind the tailgate 5, but the size and shape of the area 5A are not limited to this, and include the movable range of the tailgate 5 and have security. It can be set as appropriate in consideration, and may be, for example, a circle centered on the transmission antenna 14a.

[1-2. Configuration of switching control device]
Next, the configuration of the ECU 10 will be described. The ECU 10 inputs and outputs signals to and from a CPU that executes various arithmetic processes, a ROM that stores programs and data necessary for the control, a RAM that temporarily stores calculation results and the like in the CPU, and the outside. Input / output ports, a timer for counting control time, and the like. On information of the opening operation switch 13a and the closing operation switch 13b is input to the ECU 10. The ECU 10 is connected to a transmission antenna 14a and a reception antenna 15a.

  The ECU 10 includes a functional element as a first determination unit (first determination unit) 11 that determines whether or not the portable device 2 is in the area 5 </ b> A, and the portable device 2 is outside the area 5 </ b> A after the determination by the first determination unit 11. Functional elements as the second determination unit (second determination means) 12 for determining that the mobile device 2 has exited the area 5A when the second determination unit 12 determines that the portable device 2 has exited the area 5A. And a functional element as an opening / closing control unit (opening / closing means) 13 to be started. Further, the ECU 10 has a functional element as a vehicle-side transmitter 14 that transmits a confirmation signal to the portable device 2 and a functional element as a vehicle-side receiver 15 that receives a response signal from the portable device 2. .

  The first determination unit 11 determines a precondition of the present control device, and starts the determination when the operation switch 3 is input. The first determination unit 11 determines that the portable device 2 is in the area 5 </ b> A when the operation switch 3 is operated and the vehicle-side receiving unit 15 receives the ID response signal from the portable device 2. On the other hand, if the vehicle-side receiving unit 15 does not receive the ID response signal even when the operation switch 3 is operated, it is determined that the portable device 2 is not in the area 5A (that is, outside the area 5A). If the first determination unit 11 determines that the portable device 2 is in the area 5A, the first determination unit 11 determines that it is a legitimate user who has operated the operation switch 3 of the tailgate 5, and all the vehicles 1 including the tailgate 5 are included. A command for locking / unlocking the door is transmitted to the opening / closing control unit 13. Moreover, if the 1st determination part 11 determines with the portable device 2 being in the area 5A, it will transmit the result to the vehicle side transmission part 14. FIG.

When the first determination unit 11 determines that the portable device 2 is in the area 5A, the vehicle-side transmission unit 14 confirms the position in the area 5A at a predetermined period T ₁ (for example, 1 second) set in advance. Send a signal (confirmation signal). When the portable device 2 exists in the area 5A, the reception unit 25 receives a position confirmation signal via the reception antenna 25a, and transmits a position response signal (response signal) from the transmission unit 24 via the transmission antenna 24a. To do. On the other hand, when the portable device 2 does not exist in the area 5A, the position confirmation signal is not received by the receiving unit 25, and therefore the position response signal is not transmitted.

Here, the predetermined cycle T _{1 at} which the vehicle-side transmitter 14 transmits the position confirmation signal is 1 second, but the predetermined cycle T ₁ is not limited to this. Since the cycle for transmitting the position confirmation signal by the vehicle-side transmitter 14 is a determination cycle by the second determination unit 12, a short cycle (for example, 0. 5 seconds, etc.), and if it is desired to be safer, it may be set to a period with a margin (for example, 1.5 seconds).

The vehicle side receiver 15 receives the position response signal transmitted from the transmitter 24 of the portable device 2.
After the first determination unit 11 determines that the portable device 2 is in the area 5 </ b> A, the second determination unit 12 does not receive the position response signal from the portable device 2 after the vehicle-side reception unit 15 receives the position response signal. It is determined that the machine 2 has gone out of the area 5A. At this time, in consideration of a time lag from when the vehicle side transmission unit 14 transmits the position confirmation signal to when the vehicle side reception unit 15 receives the position response signal, the second determination unit 12 has a predetermined waiting time T _2. (e.g., about 1 second) provided, the vehicle-side reception unit 15 may determine whether the received location response signal during this waiting time T _2. The predetermined waiting time T ₂ are, but comparable with a predetermined period T ₁ the vehicle-side transmitting unit 14 transmits a position confirmation signal is preferred, may be set longer than the predetermined period T _1, also If it is longer than the lime lag, it may be set shorter than the predetermined period T ₁ .

The determination by the second determination unit 12 is performed for a predetermined time t set in advance. The predetermined time t can be set to an appropriate value, and may be determined depending on how many times the position confirmation signal is transmitted by the vehicle-side transmission unit 14. For example, the predetermined time t may be a value (t = T ₁ × N) obtained by multiplying the period T _{1 at} which the position confirmation signal is transmitted and the number of times the position confirmation signal is transmitted (N times). That is, when the first determination unit 11 determines that the portable device 2 is in the area 5A, the vehicle-side transmission unit 14 transmits a position confirmation signal into the area 5A. When the side receiving unit 15 continues to receive the position response signal (in other words, when the portable device 2 continues to exist in the area 5A), the determination by the second determination unit 12 ends.

  When the opening / closing control unit 13 receives a command for locking / unlocking all the doors of the vehicle 1 from the first determination unit 11, the opening / closing control unit 13 locks or unlocks all the doors of the vehicle 1 including the tailgate 5. When the second determination unit 12 determines that the portable device 2 has moved out of the area 5A, the opening / closing control unit 13 controls the opening / closing mechanism provided in the tail gate 5 to open and close the tail gate 5. Execute.

[2. Action, effect]
Since the vehicle door opening / closing control apparatus according to the present embodiment is configured as described above, the opening / closing control of the tailgate 5 is performed according to the flowchart shown in FIG. Each of the following steps is performed by each function (means) assigned to the hardware of the computer being operated by software (computer program).

This control device starts when one of the opening operation switch 3a for opening the tailgate 5 and the closing operation switch 3b for closing the tailgate 5 is operated.
As shown in FIG. 3, first, in step S10, it is determined whether or not the flag F = 0. Here, the flag F is a variable for checking whether or not the above-described precondition is satisfied, and the flag F = 0 is set at the start of control. Therefore, at the start of control, the YES route is obtained in step S10, and the process proceeds to step S20. In step S20, an ID confirmation signal is transmitted from the vehicle side transmitter 14 into the area 5A.

  When the portable device 2 exists in the area 5A, the receiving unit 25 of the portable device 2 receives the ID confirmation signal. Then, the ID collation unit 21 provided in the control unit 20 collates the vehicle ID with the portable device ID. When the vehicle ID and the portable device ID match, an ID response signal is transmitted from the transmission unit 24. . On the other hand, if the vehicle ID and the portable device ID do not match, it means that a person who is not a legitimate user has operated the operation switch 3, and therefore the ID response signal is not transmitted.

  In step S30, the first determination unit 11 determines whether or not the vehicle-side reception unit 15 has received an ID response signal. When it is determined that the ID response signal has been received (that is, when the portable device 2 exists in the area 5A), it is a legitimate user who has operated the operation switch 3, so the process proceeds to the YES route, and the opening / closing control is performed. All the doors of the vehicle 1 are locked / unlocked by the part 13 (step S40). On the other hand, when it is determined in step S30 that the vehicle-side receiver 15 does not receive the ID response signal, that is, when the ID response signal is not transmitted from the portable device 2, the operation switch 3 is operated by the portable device 2. Since the person is not a person (who is not a legitimate user), the process proceeds to the NO route to end the flowchart, and the tailgate 5 does not operate.

  In step S40, when all the doors of vehicle 1 are locked / unlocked, a timer is started in ECU 10 (step S50), and flag F is set to 1 (step S60). In step S70, a position confirmation signal is transmitted from the vehicle-side transmitter 14 into the area 5A. When the portable device 2 exists in the area 5A, the reception unit 25 of the portable device 2 receives the position confirmation signal, and the transmission unit 24 of the portable device 2 transmits the position response signal. On the other hand, when the portable device 2 does not exist in the area 5A, the position confirmation signal cannot be received, and therefore the position response signal is not transmitted.

In step S80, the second determination unit 12, the determination vehicle-side receiving unit 15 of whether or not it has received a location response signal within a _second predetermined waiting time T is performed. If it is determined that the position response signal has been received, since the portable device 2 exists in the area 5A, the process proceeds to the YES route, and it is determined whether it is within the predetermined time t after starting the timer. Performed (step S90). When the control is started, the process returns because it is within the predetermined time t, and the process returns to step S10. In step S10, it is determined whether or not the flag F = 0, but if the return is made, the flag F is set to 1, so the process proceeds from the NO route to step S70, and again enters the area 5A from the vehicle-side transmission unit 14. position confirmation signal is transmitted (step S70), the vehicle-side reception unit 15 of whether or not it has received a location response signal within a _second predetermined standby time T determination is repeated (step S80).

In step S80, the second determination unit 12, when the vehicle-side receiving unit 15 is determined that it has not received the location response signal within a predetermined waiting time T _2, since the portable device 2 goes out of the area 5A The process proceeds to the NO route, and the opening / closing control unit 13 starts the operation of the tailgate 5 (step S100). That is, the determination in step S80 is for grasping the position of the portable device 2 and reliably preventing contact between the user and the tailgate 5. Further, it is determined whether or not the signal is received within the predetermined waiting time T ₂ at the time of this determination. The vehicle-side receiving unit 15 receives the position response signal after the vehicle-side transmitting unit 14 transmits the position confirmation signal. This is because a time lag (time shift) may occur. In step S100, when the operation of the tailgate 5 is started, the timer is stopped and reset (step S110), the flag F is returned to 0 (step S120), and the flowchart ends.

On the other hand, in step S80, the second determination unit 12, when the vehicle-side receiving unit 15 receives the location response signal within a predetermined waiting time T _2, it is determined that the predetermined time t has elapsed in step S90, the The timer is stopped and reset (step S130), the flag F is returned to 0 (step S140), and the flowchart ends. That is, the determination in step S90 is that the tailgate 5 is determined if it remains in the area 5A for a predetermined time t from the locking / unlocking of all the doors, even if the operation switch 3 is operated by an authorized user. This is because it is determined that the operation is not necessary and the operation is not performed. In this case, all the doors of the vehicle 1 are locked / unlocked, but the tailgate 5 does not start operation.

  Therefore, according to the vehicle door opening / closing control device according to the present embodiment, after the first determination unit 11 determines that the portable device 2 is in the area 5A, the second determination unit 12 determines that the portable device 2 is in the area. If it determines with having come out of 5A, since the action | operation of the tailgate 5 is started, it can prevent reliably that the user who has the portable device 2 contacts the tailgate 5. In addition, since the first determination unit 11 and the second determination unit 12 perform the two-stage determination before the opening and closing operation of the tailgate 5, there is no need to provide a new sensor or the like, and an increase in cost can be suppressed. it can.

Further, the vehicle 1 is provided with a vehicle-side receiver 15 that receives a response signal of the portable device 2, and both the first determination unit 11 and the second determination unit 12 are connected to the vehicle-side reception unit 15 from the portable device 2. Since the determination is made based on whether or not the response signal is received, the determination can be reliably performed with a simple configuration.
In addition, the vehicle 1 is provided with a vehicle-side transmission unit 14 that transmits a confirmation signal to the portable device 2, and after the first determination unit 11 determines that the portable device 2 is in the area 5 </ b> A, a predetermined value is transmitted to the portable device 2. Since the confirmation signal is transmitted in a cycle, the vehicle-side transmission unit 14 does not need to continuously transmit the confirmation signal, and energy consumption can be reduced.

In addition, since the area 5A is set to be a movable range of the tailgate 5, that is, a range that passes when the tailgate 5 is opened and closed, it is more reliable that the user contacts the tailgate 5. Furthermore, since the operation of the tailgate 5 is started immediately when the user goes out of the area 5A, the convenience is good.
In the present embodiment, the transmission range of the ID confirmation signal used for the determination by the first determination unit 11 and the transmission range of the position confirmation signal used for the determination by the second determination unit 12 are both within the same area 5A. Since the transmission power of the signal is set so as to become, the setting of the vehicle side transmission unit 14 can be simplified.

Moreover, since the opening operation switch 3a for opening the tailgate 5 is provided in the tailgate 5, intuitive operation is possible, and the closing operation switch 3b for closing the tailgate 5 is not the tailgate 5. Since it is provided on the vehicle body, it can be operated at a position where it can be easily reached, and operability is good.
Moreover, since the determination by the second determination unit 12 performed after the first determination unit 11 determines that the portable device 2 is in the area 5A is performed only for the predetermined time t, the predetermined time t has elapsed. When the portable device 2 continues to exist in the area 5A, the opening / closing operation of the tailgate 5 is not started. Therefore, the operation of the tailgate 5 is not started when the operation of the tailgate 5 is unnecessary, for example, when the operation switch 3 is operated by mistake. In addition, when the tail gate 5 is intentionally opened slightly by hand, the tail gate 5 is unlocked by operating the opening operation switch 3a, and the tail gate 5 can be manually opened a little. At this time, since the portable device 2 is in the area 5A, the operation of the tailgate 5 is not started. Thereby, the tailgate 5 can be manually opened and an umbrella or the like can be taken out, and convenience can be improved while ensuring safety.

  In addition, by applying the present opening / closing control device to the tailgate 5 having an open top where it is difficult to estimate the movement trajectory (movable range), it is possible to reliably prevent the user from coming into contact with the tailgate 5 having a heavy weight, and safety. Can be increased.
