  Thus, in the system of the present embodiment, wireless communication is performed between the in-vehicle device 10 and the transmitter 18 so that the vehicle occupant does not insert the vehicle key into the door key cylinder or takes the vehicle key. The vehicle door can be locked / unlocked (smart function).

  In the system of the present embodiment, when the vehicle door is locked / unlocked without the vehicle occupant inserting the vehicle key into the door key cylinder or taking the vehicle key as described above, When the command for blinking the hazard lamp is supplied from the ECU 30 to the body ECU 34, the hazard lamp blinks and a buzzer sounds (an answer back function linked to key operation). At this time, the number of flashes of the hazard lamp and the method of sounding the buzzer may be different depending on whether the vehicle door is locked or unlocked. For this reason, when the vehicle door is locked or unlocked by wireless communication between the in-vehicle device 10 and the transmitter 18, it is possible to notify the vehicle occupant of this by visual or auditory sense.

  In addition, when the vehicle door is unlocked without the vehicle occupant inserting the vehicle key into the door key cylinder or taking the vehicle key as described above, the door ECU 30 moves to the body ECU 34 to the vehicle door. When the provided lamps that illuminate the feet of passengers and instructions for lighting the interior of the vehicle are supplied, the lamps are turned on (illumination function). For this reason, when the vehicle door is unlocked by wireless communication between the in-vehicle device 10 and the transmitter 18, particularly when the occupant gets on at night or in a dark parking lot, the ride can be smoothly performed. it can. When the vehicle door is unlocked in this way, instead of the illumination function described above or together with the illumination function, the door ECU 30 sends a boarding guide or radio broadcast from the vehicle interior speaker or display display to the body ECU 34. Speaker output or display output may be executed by supplying a command for playing a CD or DVD (boarding function).

  Further, when the vehicle occupant is locked without inserting the vehicle key into the door key cylinder or taking the vehicle key as described above, the intrusion sensor 48 is connected from the door ECU 30 to the security ECU 36. The security mode is realized after that by supplying a command to shift to the security mode that warns against the vehicle intrusion by using (security function linked to key operation). For this reason, the vehicle can be automatically protected from the vehicle intrusion after locking by the wireless communication between the in-vehicle device 10 and the transmitter 18.

  By the way, in this embodiment, the in-vehicle device 10 is provided with a notification of forgetting to operate, remote operation of in-vehicle devices using an actuator, response result notification after a remote operation request, help net function, answer back function, especially during parking of the vehicle after the ignition is turned off. When each function such as the above is executed, the operation is performed using the electric power of the in-vehicle battery 50. The in-vehicle battery 50 is a chargeable / dischargeable battery, and the charging is performed by supplying electric power from a generator that generates power by rotating the engine as vehicle power. For this reason, when the remaining capacity of the in-vehicle battery 50 is low when the vehicle is parked after the ignition is turned off, the operation of the actuator and communication device, the blinking of the hazard lamp, etc. accompanying the remote operation or forgetting operation notification are appropriately performed. I can't do that. Therefore, in consideration of this point, it is conceivable to uniformly stop all functions to be executed by power-off of the in-vehicle battery 50 when the remaining capacity of the in-vehicle battery 50 falls below a predetermined value. However, such a configuration is not appropriate for effectively performing functions such as remote operation of an in-vehicle device by an actuator, notification of forgetting operation to a vehicle user, and notification of a response result after a remote operation request.

  Therefore, in consideration of such points, the system of the present embodiment performs each function effectively in accordance with the above-described various functions according to the storage state of the in-vehicle battery 50 so that each function can be effectively exhibited. Yes. Hereinafter, with reference to FIG.2 and FIG.3, the characteristic part of a present Example is demonstrated. FIG. 2 is a diagram showing priorities of various functions set in the system of the present embodiment. FIG. 3 shows a flowchart of an example of a control routine executed by the vehicle-mounted device 10 in the system of this embodiment.

  In the present embodiment, the power supply ECU 54 of the in-vehicle device 10 detects the remaining capacity of the in-vehicle battery 50, but a plurality of (three in this embodiment) threshold values (SH1, SH2, SH3) relating to the remaining capacity of the in-vehicle battery 50 in advance. ) Is remembered. The threshold value SH1 is the remaining capacity of the in-vehicle battery 50 where it is assumed that the life reduction of the in-vehicle battery 50 becomes noticeable when reaching a state below that value, and is set to 70%, for example. Further, the threshold value SH2 is a remaining capacity of the in-vehicle battery 50 that cannot properly start the engine that is the vehicle power when a state equal to or lower than the threshold value SH2, and is set to, for example, 50% lower than the threshold value SH1. Furthermore, the threshold value SH3 is a remaining capacity of the in-vehicle battery 50 that cannot properly operate a predetermined actuator or the transceiver 20 when reaching a state below that value, and is set to 35%, for example, lower than the threshold value SH2. ing.

  In addition, the master ECU 22 stores a priority indicating a priority order for supplying power from the in-vehicle battery 50 for each of a plurality of functions to be executed in advance including a remote operation of the in-vehicle device.

  Forgotten operation notification function from vehicle-mounted device 10 to vehicle user possessing operation terminal 12, response result notification function after remote operation request, answer back function linked to key operation when vehicle door is locked / unlocked, vehicle door The illumination function and boarding function at the time of unlocking are performed by the vehicle user who is associated with the remote operation of the in-vehicle device or with the lock / unlock of the vehicle door based on the wireless communication between the in-vehicle device 10 and the transmitter 18. Since this is a voluntary operation in a vehicle without direct intention, the urgency is poor, the priority in supplying power is set to the lowest, and the remaining capacity of the in-vehicle battery 50 is the above threshold value. The priority level 3 is set so that the power supply is not performed and the function is stopped when SH1 or less.

  In addition, remote operation functions such as lighting of lights for car finder and parking on the street and opening of windows among remote operations of in-vehicle devices using actuators are intended to improve the convenience of vehicle users for vehicle operation. Because it is a function, it is less urgent than a function that improves security, the priority in supplying power is set to an intermediate level, and the remaining capacity of the in-vehicle battery 50 is less than the above threshold SH2. In this case, priority 2 is set so that the function is stopped without power supply. In addition, remote operation functions such as vehicle door lock and window closing, help net function for requesting relief from a rescue organization using the help net center 16, and security functions linked to key operations make the vehicle more secure, safe and secure. Therefore, the priority for power supply is set at the highest level with urgency, and power is supplied when the remaining capacity of the in-vehicle battery 50 falls below the threshold value SH3. Is set to priority 1 at which the function is stopped without being performed.

  The power supply ECU 54 periodically detects the remaining capacity of the in-vehicle battery 50 using the remaining capacity sensor 52, and the detected remaining capacity belongs to any level region divided by the threshold values SH1, SH2, and SH3. Is determined, and information indicating the level is supplied to the master ECU 22. Then, master ECU 22 detects the level of the remaining capacity of in-vehicle battery 50 based on information from power supply ECU 54 (step 100).

  When the remaining capacity exceeds the threshold value SH1 as a result of the level detection of the remaining capacity of the in-vehicle battery 50 (when a negative determination is made at step 102), the master ECU 22 performs the routine without any further processing. When the remaining capacity is equal to or less than the threshold value SH1 and exceeds the threshold value SH2 (at the time of an affirmative determination at step 102 and a negative determination at step 104), the operation set to priority 3 is performed thereafter. The forget-notification function and the response result notification function after a remote operation request (spontaneous function of the vehicle accompanying the remote operation of the in-vehicle device), the answer back function, the illumination function, and the boarding function are restricted (step 106).

  Further, when the remaining capacity of the in-vehicle battery 50 is equal to or less than the threshold value SH2 and exceeds the threshold value SH3 (at the time of an affirmative determination at step 104 and a negative determination at step 108), thereafter, the function of priority 3 is restricted. In addition, the remote operation function for the convenience of the vehicle user, such as lighting of lights and window opening, set to priority 2 is restricted (step 110). Further, when the remaining capacity of the in-vehicle battery 50 is equal to or less than the threshold value SH3 (when an affirmative determination is made in step 108), in addition to the restriction of various functions of priority 3 and priority 2 described above, further priority is given. In addition to restricting the remote operation function for setting the vehicle security such as the vehicle door lock and window closing, the help net function, and the security function linked to the key operation (step 112), the door ECU 30 is set. A process for forcibly locking the vehicle door is performed by making a vehicle door lock operation request (step 114).

  As described above, in the system according to the present embodiment, when the remaining capacity of the in-vehicle battery 50 sufficiently exceeds the threshold value SH1, all the above-described various functions can be executed, while when the remaining capacity is equal to or less than the threshold value SH1. These functions can be limited in stages according to the level of the remaining capacity. Specifically, when the remaining capacity of the in-vehicle battery 50 reaches a threshold value SH1 or less, an answer function that flashes a hazard lamp or the like in conjunction with a spontaneous function of a forgetting operation notification or a response result notification after a remote operation request and a key operation The back function, illumination function, and boarding function are stopped, and when the remaining capacity reaches a threshold value SH2 that is smaller than the threshold value SH1, the remote operation function for the convenience of the vehicle user is stopped, and the remaining function is further stopped. When the capacity reaches a threshold value SH3 or less that is smaller than the threshold value SH2, all functions including a remote operation function and a help net function for enhancing the security of the vehicle can be stopped. According to such a configuration, as the remaining capacity of the in-vehicle battery 50 decreases, various functions based on wireless communication between the in-vehicle device 10 and the external communication device are limited step by step in order of priority. It is possible to suppress the rise and deterioration.

  In addition, according to the above configuration, the vehicle door is locked / unlocked based on wireless communication between the in-vehicle device 10 and the transmitter 18 such as a spontaneous function of notification of forgetting operation or a response result notification after a remote operation request or an answer back function. The spontaneous function performed in conjunction with the vehicle is stopped when the in-vehicle battery 50 begins to lose its life, but the remote operation function for the convenience of the vehicle user can be executed until the in-vehicle battery 50 becomes unable to start the engine. In addition, a remote operation function, a help net function, and the like that enhance the security of the vehicle can be executed until the in-vehicle battery 50 becomes unable to start the engine and further disables the actuator and the transceiver 20. In this regard, a remote operation function for helping the vehicle user can be secured until the remaining capacity of the in-vehicle battery 50 is reduced, and further, a remote operation function and a help net function that can enhance the security of the vehicle. The security function linked to the key operation can be sufficiently ensured until the remaining capacity of the in-vehicle battery 50 is significantly reduced.

  In order to improve the security of the vehicle, it is effective to secure a function to improve the security even when the in-vehicle battery 50 is significantly reduced in the remaining capacity. It is appropriate to secure a function that enhances the security of the vehicle rather than a spontaneous function or a remote operation function that improves the convenience of the vehicle user until the remaining capacity of the in-vehicle battery 50 is significantly reduced. Therefore, according to the remote operation system of the present embodiment, the forgotten operation notification function, the response result notification function, and the remote operation function of the in-vehicle device are performed by executing stepwise function restrictions according to the storage state of the in-vehicle battery 50. In addition, various functions based on wireless communication between the in-vehicle device 10 and the external communication device can be effectively exhibited in accordance with the respective priorities.

  In this embodiment, when all the functions are stopped when the remaining capacity of the in-vehicle battery 50 is equal to or less than the threshold value SH3, all the vehicle doors are forcibly locked. For this reason, it is possible to reliably prevent the vehicle door from being left in an unlocked state even when remote operation becomes impossible due to a decrease in battery capacity, thereby preventing vehicle entry and theft. It is possible to secure the prevention and further improve the security.

  In the above embodiment, the in-vehicle device 10 is in the “on-vehicle control device” described in the claims, the operation terminal 12 and the transmitter 18 are in the “portable terminal” in the claims, and the service center 14. And the help net center 16 correspond to the “center” described in the claims, respectively, and the in-vehicle device 10 executes the processing of step 100 in the routine shown in FIG. The described “in-vehicle battery storage state detection means” executes the processing of steps 106, 110, and 112, and the “function limiting means” described in the claims executes the processing of step 114. The “automatic door lock means” recited in the claims is realized.

  By the way, in the above-described embodiment, as described above, when the remaining capacity of the in-vehicle battery 50 is equal to or less than the threshold value SH1, a plurality of functions including remote operation of the in-vehicle device step by step according to the level of the remaining capacity. However, every time the function is restricted, the in-vehicle device 10 notifies the operation terminal 12 through the service center 14 and notifies the vehicle user from the input / output unit 64 of the operation terminal 12. Also good.

  For example, when the spontaneous function of notification of forgetting operation or response result notification after a remote operation request is restricted, the fact that the in-vehicle device 10 notifies the operation terminal 12 through the service center 14 and the input / output unit 64 of the operation terminal 12 To the vehicle user, “Since the forgotten operation notification and the response result notification after the remote operation request are stopped” are output by voice or display. Further, when the remote operation function for the convenience of the vehicle user is restricted, the fact is notified from the in-vehicle device 10 to the operation terminal 12 through the service center 14, and from the input / output unit 64 of the operation terminal 12 to the vehicle user. Outputs words such as “Remote operation related to convenience will be stopped afterwards” by voice or display. Further, when the remote operation function for enhancing security is restricted due to the remaining capacity of the in-vehicle battery 50 reaching the threshold value SH3 or less, the fact is operated from the in-vehicle device 10 through the service center 14 immediately before reaching the state. The terminal 12 is notified, and the words such as “the remote operation for improving the security is stopped” is output from the input / output unit 64 of the operation terminal 12 to the vehicle user by voice or display.

  According to such a configuration, it is possible to notify the vehicle user via the operation terminal 12 that the function is restricted in accordance with the storage state of the in-vehicle battery 50. Thus, the vehicle user is notified of the response after the function restriction. It becomes possible to make it easy to take. In this case, the in-vehicle device 10 notifies the operation terminal 12 through the service center 14 that the function restriction is performed every time the vehicle function restriction is performed. Means "are realized.

  In the above embodiment, as described above, when the remaining capacity of the in-vehicle battery 50 reaches the threshold value SH2 or less, the remote operation function for the convenience of the vehicle user is limited. Since the remaining capacity of the in-vehicle battery 50 that makes it impossible to start the engine properly when the following state is reached, if it is possible to start the engine, JAF or the like from the in-vehicle device 10 through the service center 14 together with the vehicle position information is possible. It may be reported to other vehicle maintenance companies. According to such a configuration, when the remaining capacity of the in-vehicle battery 50 reaches a state where the engine cannot be started properly, this state can be automatically notified to the vehicle maintenance company, thereby causing a decrease in the battery capacity. Thus, in order to maintain a vehicle that has become unable to start the engine, preparations such as ordering of a new in-vehicle battery 50 can be made thoroughly before vehicle maintenance, and subsequent vehicle maintenance can be performed quickly. In this case, when the in-vehicle device 10 reaches a state where the remaining capacity of the in-vehicle battery 50 cannot start the engine properly (threshold value SH2 or less), the vehicle maintenance such as JAF is automatically performed to the effect that the engine cannot be started. By reporting to the company, the “maintenance request reporting means” described in the scope of claims is realized.

  In the above-described embodiment, a plurality of functions including remote operation of the in-vehicle device belong to any of the four areas where the remaining capacity of the in-vehicle battery 50 is divided by the three threshold values SH1, SH2, and SH3. However, it may be limited in a stepwise manner depending on which of the three regions divided by at least two threshold values, and more than four threshold values. It is good also as applying to what uses. Moreover, although the priority of each of the plurality of functions is set with a pattern as shown in FIG. 2B, it may be set with another pattern.

  In the above embodiment, the vehicle door lock and the window closing are cited as the remote operation for enhancing the security of the vehicle. However, the indoor curtain is closed, the inside of the vehicle is photographed by the camera, and the warning mode using the intrusion sensor 48 is used. You may include a set of In addition, lighting operations such as lighting were cited as remote operations for the convenience of vehicle users, but defogger operation, defroster operation, route search to the next destination, side brake release to prevent freezing Etc. may be included.

  Furthermore, the system of the above embodiment includes an in-vehicle device 10 installed in a vehicle, an operation terminal 12 carried by a vehicle user, and a service center 14 for information management when performing remote operation of in-vehicle devices. However, the present invention is not limited to this, and may be applied to a system including the in-vehicle device 10 and the operation terminal 12 that do not have the service center 14.

It is a block diagram of the system which is one Example of this invention. It is a figure showing the priority of the various functions set in the system of a present Example. It is a flowchart of an example of the control routine which an onboard equipment performs in the system of a present Example.
