Detects the outdoor temperature (outside air temperature). The outside air temperature sensor 22 is communicably connected to the air conditioner ECU 20 via a one-to-one communication line or the like, and a detection signal corresponding to the detected outdoor temperature is input to the air conditioner ECU 20.

The air conditioner ECU 20 is an electronic control unit that performs various controls related to the air conditioner 10. The function of the air conditioner ECU 20 may be realized by any hardware, software, or a combination thereof. For example, a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), an auxiliary storage device, and the like. It may be configured around a microcomputer including an I / O (Input-Output interface) and the like. Hereinafter, the same applies to the engine ECU 40 and the body ECU 80. The air conditioner ECU 20 includes, for example, an air conditioner control unit 201 as a functional unit realized by executing one or more programs stored in a ROM, an auxiliary storage device, or the like on a CPU.

The air conditioner control unit 201 operates and controls the air conditioner 10 according to a set state such as a set temperature and a mode (a plurality of outlet modes or defroster modes depending on a combination of outlets). Specifically, the air-conditioning control unit 201 operates and controls the air-conditioning device 10 so that, for example, the room temperature becomes a set temperature based on the detected values of the room temperature sensor 21, the outside air temperature sensor 22, and the like. Further, the air-conditioning control unit 201 starts the air-conditioning device 10 in response to the air-conditioning start request from the remote control support control unit 402, which will be described later, and operates the air-conditioning device 10 in response to the setting contents included in the air-conditioning start request. Take control.

The air conditioner ECU 20, the engine ECU 40, various ECUs including the body ECU 80, and the DCM90 are communicably connected to each other through, for example, an in-vehicle network based on a communication protocol such as CAN (Controller Area Network).

The engine 30 (an example of a drive device) is a drive force source for the vehicle 2, and is also a drive force source for the compressor in the refrigeration cycle of the air conditioner 10, specifically, the air conditioner 10. Under the control of the engine ECU 40, the engine 30 operates by burning gasoline, light oil, or the like supplied from a fuel tank (not shown) via a fuel pump (not shown) in a cylinder. The engine 30, specifically, various actuators incorporated in the engine 30 (fuel injection device for injecting fuel, ignition device for igniting gasoline injected into the cylinder, electric power for changing the opening / closing timing of intake and exhaust valves). The motor, etc.) is communicably connected to the engine ECU 40 via a one-to-one communication line or the like, and operates in response to a control command transmitted from the engine ECU 40.

The engine ECU 40 is an electronic control unit that performs various control processes of the engine 30 including a starter (not shown).

The engine control unit 401 responds to an operation state by the driver of the vehicle 2 (for example, the accelerator opening, a selected shift stage of a transmission (not shown), etc.), an environmental state around the vehicle 2 (for example, outside air temperature), and the like. The operation of the engine 30 is controlled. For example, the engine control unit 401 starts the engine 30 when the ignition switch (IG switch) is turned on (IG-ON) or when an engine start request is input from the outside. Specifically, the engine control unit 401 switches a relay (not shown) for energizing the starter to a connected state to drive the starter, and appropriately controls the fuel injection device and the ignition device according to the cranking by the starter. By doing so, the engine 30 is started.

The remote control support control unit 402 transmits an engine start request and an air conditioning start request to the engine control unit 401 and the air conditioning control unit 201, respectively, in response to the start request received from the terminal 200 via the center server 100. As a result, the engine 30 and the air conditioner 10 are started. Further, the remote operation support control unit 402 transmits an engine stop request and an air conditioner stop request to the engine control unit 401 and the air conditioner control unit 201, respectively, when a predetermined end condition is satisfied after the engine 30 and the air conditioner 10 are started. By doing so, the air conditioner 10 and the engine 30 are stopped. For example, the remote control support control unit 402 starts from the start itself of the engine 30 and the air conditioner 10 as an end condition, and when the start operation time included in the start request or a predetermined set operating time elapses, the air conditioner 10 and the air conditioner 10 and The engine 30 may be stopped. Further, for example, when the remote control support control unit 402 determines that the room temperature is included in the start request or has reached a preset set temperature after the start of the engine 30 and the air conditioner 10 as an end condition. In addition, the air conditioner 10 and the engine 30 may be stopped. Further, for example, when the remote control support control unit 402 receives a signal from the terminal 200 via the center server 100 that the operation of stopping the engine 30 and the air conditioner 10 has been executed by the DCM 90 as an termination condition. In addition, the air conditioner 10 and the engine 30 may be stopped.

The function of the remote control support control unit 402 may be provided in the air conditioner ECU 20, or may be provided in another ECU capable of communicating with the air conditioner ECU 20 and the engine ECU 40 through an in-vehicle network based on a communication protocol such as CAN. ..

The vehicle information transmission unit 403 acquires vehicle information input from various sensors and the like from a RAM buffer and the like, and transmits the vehicle information to the center server 100 via the DCM 90. In the present embodiment, the vehicle information transmission unit 403 receives information corresponding to the output signals input from the shift sensor 50 and the PKB switch 60 in response to the vehicle information acquisition request received from the center server 100 by the DCM90, that is, the vehicle. Information regarding the shift position information of the transmission (not shown) of 2 and information (PKB operation information) regarding the presence / absence of operation of the parking brake (not shown) of the vehicle 2 are transmitted to the center server 100 via the DCM90.

The shift sensor 50 detects the shift position selected by the transmission (an example of the power transmission device) mounted on the vehicle 2. In the case of an automatic transmission, the shift position of the transmission includes, for example, P range, D range, N range, R range and the like. In the transmission, the shift position determines whether the power of the engine 30 is transmitted to the drive wheels or not. Therefore, the shift position information can be transmitted from the engine 30 to the drive wheels by the transmission (transmission possible). Or any state where transmission is not possible). The shift sensor 50 is communicably connected to the engine ECU 40 through, for example, a one-to-one communication line or an in-vehicle network based on a communication protocol such as CAN, and an output signal corresponding to the detected shift position is input to the engine ECU 40. ..

The PKB switch 60 outputs an ON signal or an OFF signal corresponding to the operating state (either the operating state or the releasing state) of the mechanical or electric parking brake (an example of the rotation blocking device) mounted on the vehicle 2. .. The PKB switch 60 is communicably connected to the engine ECU 40 through an in-vehicle network based on a communication protocol such as a one-to-one communication line or CAN, and an output signal (ON signal or OFF signal) corresponding to the operating state of the parking brake is output. ) Is input to the engine ECU 40.

The vehicle speed sensor 70 detects the vehicle speed of the vehicle 2. The vehicle speed sensor 70 is communicably connected to the engine ECU 40 through, for example, a one-to-one communication line or an in-vehicle network based on a communication protocol such as CAN, and an output signal corresponding to the detected vehicle speed is input to the engine ECU 40.

The body ECU 80 is an electronic control unit that drives an actuator (for example, a door lock motor) that locks and unlocks the door of the vehicle 2 to control the locked / unlocked state of the door of the vehicle 2. The door of the vehicle 2 includes a side door for passengers to get in and out of the vehicle 2, a back door for accessing the luggage compartment, a trunk lid, and the like. Hereinafter, the state in which the vehicle 2 is locked means a state in which all of the plurality of doors of the vehicle 2 are locked, and the state in which the door of the vehicle 2 is unlocked means that at least one of the plurality of doors is locked. It means the unlocked state.

For example, the body ECU 80 receives an unlocking signal in the RF (Radio Frequency) band wirelessly transmitted from the electronic key to the vehicle 2 by a tuner (not shown) mounted on the vehicle 2. The door of the vehicle 2 is unlocked in response to a command from the verification ECU (not shown) that performs the authentication process.

Further, for example, the body ECU 80 is from a collation ECU that performs authentication processing by exchanging a wireless signal with the electronic key when a user carrying the electronic key operates a trigger switch provided on the door or the like of the vehicle 2. The door of the vehicle 2 is unlocked in response to the command.

Further, for example, the body ECU 80 periodically outputs the locked / unlocked state of the door of the vehicle 2, that is, the state information regarding whether the door is locked or unlocked, to the engine ECU 40 or the like through an in-vehicle network such as CAN. ..

The DCM90 bidirectionally communicates with the center server 100 through, for example, a predetermined communication network NW1 (hereinafter, the same applies to the communication network NW2) including a mobile phone network or an Internet network having a large number of base stations as terminals. It is a device. As described above, the DCM90 is communicably connected to various ECUs such as the air conditioner ECU 20, the engine ECU 40, and the body ECU 80 through an in-vehicle network such as CAN.

The center server 100 is interposed between the vehicle 2 and the user's terminal 200, and controls the remote operation of the vehicle 2 by the user using the terminal 200, specifically, the vehicle 2 based on the remote operation from the terminal 200. Controls the start of the engine 30. The center server 100 includes a communication device 110 and a processing device 120.

The communication device 110 is controlled by the processing device 120 (specifically, the communication processing unit 1201), and both of the vehicle 2 (specifically, the DCM90) and the terminal 200 via the communication networks NW1 and NW2. It is a device that communicates in the direction.

The processing device 120 executes various control processes in the center server 100. The function of the processing device 120 may be realized by any hardware, software, or a combination thereof, and is centered on one or more server computers including, for example, a CPU, RAM, ROM, auxiliary storage device, I / O, and the like. It may be configured in. The processing device 120 includes, for example, a communication processing unit 1201 and a vehicle information acquisition unit 1202 as functional units realized by executing one or more programs stored in a ROM or an auxiliary storage device on a CPU. It includes a determination unit 1203 and a remote operation control unit 1204.

The communication processing unit 1201 controls the communication device 110 and transmits / receives various signals (control signals, information signals, etc.) to and from the vehicle 2 and the terminal 200.

The vehicle information acquisition unit 1202 (an example of the information acquisition unit) transmits a vehicle information acquisition request requesting acquisition of vehicle information to the vehicle 2 via the communication processing unit 1201 and thereby via the communication processing unit 1201. Acquire the vehicle information received from the vehicle 2. Specifically, the vehicle information acquisition unit 1202 provides shift position information indicating a power transmission enable / disapproval state of a transmission that transmits power from the engine 30 of the vehicle 2 to the drive wheels via the communication processing unit 1201, and the vehicle 2 Information (PKB operation information) regarding the operating state of the parking brake that prevents the rotation of the drive wheels of the vehicle is acquired.

The start permission / rejection determination unit 1203 (an example of the permission / rejection determination unit) is based on the shift position information and the PKB operation information acquired by the vehicle information acquisition unit 1202, and the engine 30 based on the start request received from the terminal 200 by the communication processing unit 1201. Determine whether to allow the start of. For example, when the transmission of the vehicle 2 cannot transmit the power of the engine 30 to the drive wheels and the parking brake is operating, the start permission / rejection determination unit 1203 starts the engine 30 based on the start request. to approve. The transmission of vehicle 2 cannot transmit the power of the engine 30 to the drive wheels when the shift position information indicates, for example, the P range or N range of the automatic transmission, or the neutral position of the manual transmission. Corresponds to the state. On the other hand, the start permission / rejection determination unit 1203 starts when the transmission of the vehicle 2 is in a state where the power of the engine 30 can be transmitted to the drive wheels, or when the parking brake is not operating, that is, is released. Do not allow the engine 30 to start on demand. The transmission of the vehicle 2 drives the power of the engine 30 when the shift position information indicates, for example, the position corresponding to each shift stage of the automatic transmission, the D range, the R range, or the manual transmission. It corresponds to the state where it can be transmitted to the wheel. As a result, the start of the engine 30 is permitted in a situation where the vehicle 2 starts to move, such as when the transmission of the vehicle 2 can transmit the power of the engine 30 to the drive wheels or when the parking brake is not operating. It is possible to prevent the engine 30 from starting.

The remote control control unit 1204 (an example of the control unit) controls the start of the engine 30 based on the start request received from the terminal 200 by the communication processing unit 1201. For example, the remote control control unit 1204 communicates when a start request is received from the terminal 200 by the communication processing unit 1201 and when the start permission / rejection determination unit 1203 permits the start of the engine 30 based on the start request. A start request is transmitted to the vehicle 2 via the processing unit 1201 to start the engine 30 and the air conditioner 10. On the other hand, in the remote control control unit 1204, even when the start request is received from the terminal 200 by the communication processing unit 1201, the start of the engine 30 based on the start request is not permitted by the start permission / rejection determination unit 1203. Do not start the engine 30. Then, the remote control control unit 1204 transmits a notification that the engine 30 cannot be started to the terminal 200 through the communication processing unit 1201.

The terminal 200 performs a remote control regarding the start of the vehicle 2 by transmitting a start request of the engine 30 or the like in response to a predetermined operation input from the user. The terminal 200 is, for example, a mobile terminal such as a smartphone or a tablet terminal owned by the user of the vehicle 2. Further, the terminal 200 may be a stationary terminal owned by the user of the vehicle 2, such as a desktop computer terminal. The terminal 200 includes a communication device 210, a processing device 220, and a touch panel display (hereinafter, simply referred to as “display”) 240.

The communication device 210 is a device that bidirectionally communicates with the center server 100 through the communication network NW2 under the control of the processing device 220 (specifically, the communication processing unit 2201 described later). For example, LTE (Long). Term Evolution) module.

The processing device 220 performs various control processes on the terminal 200.

It includes a permission / rejection unit 1203, a remote operation control unit 1204, and a start request canceling unit 1205.

The start request canceling unit 1205 is the start request (in operation) when the engine 30 is started and is in operation based on the start request, when the vehicle 2 is running, or when the vehicle 2 is likely to run. The start request that triggered the start of a certain engine 30) is canceled (disabled). When the vehicle 2 runs as it is without stopping the engine 30 started based on the start request, the start request may be held in a valid state. For example, there is a case where the effective time is specified in the start request. In this case, with respect to the vehicle 2 parked after traveling for a time shorter than the effective time of the specified start request, the engine 30 based on the start request held in an effective state contrary to the intention of the user. The start can be done. On the other hand, the start request canceling unit 1205 cancels the start request in such a case and prevents the engine 30 from starting based on the start request.
