It is a transmission means for transmitting to the in-vehicle device 4.

  The in-vehicle device 4 used in combination with the remote engine starter 3 is configured as an independent ECU (Electronic Control Unit). The ECU communicates with an engine ECU 11 that controls the engine 10 and an air conditioner ECU 13 that controls an air conditioner 12 (air conditioner in the vehicle interior) via an in-vehicle LAN such as CAN. As shown in FIG. 2, the in-vehicle device 4 includes a processing unit 14 composed of a microcomputer, a memory 15, a sensor input unit 16, a wireless communication unit 17, a GPS processing unit 18, an in-vehicle LAN communication unit 19, an interface unit 20, and a power supply unit 21. Etc.

Detection signals or detection values are input from the sensor 31 and the remaining fuel amount sensor 32, respectively. The position information sensor 24 detects the current position of the vehicle separately from the GPS processing unit 18. Instead of the position information sensor 24, the current position of the vehicle may be acquired from the in-vehicle navigation device. Moreover, you may acquire the present position of a vehicle based on the position data of base station 5a, 5b, ... when the radio | wireless communication part 17 connects to the mobile telephone network 5. FIG.

The vehicle interior temperature sensor 26 detects the temperature in the vehicle interior. The exhaust gas sensor 27 detects the amount of gas components (contaminants) such as HC, CO, and NOx in the exhaust gas. The noise sensor 28 detects environmental noise around the vehicle and vehicle noise generated by itself. The engine speed sensor 29 detects the engine speed. Instead of the engine speed sensor 29, the engine speed may be acquired from the engine ECU via the in-vehicle LAN.

  The surrounding space sensor 30 detects whether or not the vehicle is in a closed space such as a garage (garage) by distance sensors provided at the corners, both sides, and the roof of the vehicle. The battery remaining amount sensor 31 detects the remaining capacity of the battery. The remaining fuel sensor 32 detects the remaining amount of fuel. The remaining capacity of the battery and the remaining amount of fuel may be obtained from another ECU via the in-vehicle LAN.

  Next, the operation of this embodiment will be described with reference to FIG. The terminal device 2, the communication device 7 of the remote engine starting device 3, and the wireless communication unit 17 of the in-vehicle device 4 can communicate with each other via the mobile phone network 5. When the user starts the engine of the vehicle by remote control, a transmission operation from the terminal device 2 to the remote engine starter 3 is performed. As a result, a vehicle engine start request is transmitted from the terminal device 2 to the remote engine starter 3. When receiving the engine start request, the vehicle information acquisition unit 8 of the remote engine starter 3 detects and notifies the vehicle information indicating the vehicle surroundings including the current position of the vehicle and the state of the vehicle itself to the in-vehicle device 4. Request that.

  The in-vehicle device 4 can receive an incoming call to the wireless communication unit 17 even when the ignition switch is turned off. When receiving the vehicle information notification request, the processing unit 14 of the in-vehicle device 4 detects the current position of the vehicle by the GPS processing unit 18 or the position information sensor 24. Further, the temperature outside the vehicle compartment is detected by the outside temperature sensor 25, the environmental noise around the vehicle is detected by the noise sensor 28, and whether or not the vehicle is in a closed space such as a garage is detected by the ambient space sensor 30. . Furthermore, the relevance to the public vehicle (bus, emergency vehicle, etc.) and the conformity of the exhaust gas regulations stored in advance in the memory 15 are read out. The in-vehicle device 4 transmits a notification response including the detected or read vehicle information to the remote engine starting device 3.

  The control means 9 of the remote engine starter 3 sets control parameters based on the received vehicle information. The control means 9 reads the restriction data applied at the current position of the vehicle from the database 6 and obtains the possible idling state continuation time defined in the restriction information. Depending on the applicable regulatory information, when the temperature outside the passenger compartment (temperature) is above or below the specified value, for public vehicles such as buses, emergency vehicles such as ambulances, and vehicles that comply with exhaust gas regulations For example, the restriction may be relaxed so as to increase the duration, or application of the duration may be excluded. The control means 9 sets the idling continuation time (control parameter) within a range that does not exceed the idling state continuation possible time defined in the regulation information related to idling, including such exceptions.

  The control means 9 reads map data around the current position of the vehicle from the database 6 and determines whether or not the current position of the vehicle is an area where vehicle noise due to idling is a problem. Here, areas where vehicle noise due to idling is a problem are residential areas, areas close to libraries and nurseries, and areas where vehicle noise due to idling is not a problem are busy areas, areas along main roads, and the like. Further, the control means 9 determines whether or not the detected noise level around the vehicle (the own vehicle noise is not included because the engine is stopped) is lower than a specified value. This is because even if the map data indicates a downtown area or a main road area, there may actually be a quiet area.

  When the control means 9 determines that the current position of the vehicle is an area where the vehicle noise is a problem or the noise level around the vehicle is lower than a specified value, the air conditioning capability in the vehicle interior causing the noise and the engine at idling At least one of the upper limit value of the rotational speed and the upper limit value of the vehicle noise during idling (both are control parameters) is set to be lower than the specified value.

  The control means 9 reads the exhaust gas restriction amount during the idling period defined in the restriction information related to idling, and sets the exhaust gas restriction amount (control parameter) that can be discharged during idling within a range not exceeding the exhaust gas restriction amount. In this case, if it is determined that the current position of the vehicle is in a residential area or the vehicle is in a closed space such as a garage, the exhaust gas limit amount that can be discharged during idling is set lower than a specified value. When it is determined that the vehicle is in a closed space such as a garage, transmission of an engine start command signal may be prohibited.

  When the setting of the control parameter is completed, the remote engine starter 3 transmits the control parameter to the terminal device 2. The terminal device 2 includes a display unit, and displays the received control parameter on the screen. For example, “The idling operation duration is 5 minutes due to regulations”, “The capacity of the air conditioner is reduced because the vehicle is in a residential area”, “The engine is started because the vehicle is in a narrow space,” It was not possible. "

  The remote engine starter 3 transmits the engine start command signal and the set control parameter to the in-vehicle device 4. When receiving the start command signal, the processing unit 14 of the in-vehicle device 4 requests the engine ECU 11 to start the engine and starts the engine. The engine speed during idling operation is suppressed to be equal to or lower than the upper limit value of the engine speed determined by the control parameter. Further, the air conditioner ECU 13 starts the operation of the air conditioner 12. The air conditioning capability during idling operation can be suppressed below the air conditioning capability determined by the control parameter.

  The in-vehicle device 4 transmits a start result indicating whether or not the engine 10 and the air conditioner 12 have started normally to the remote engine starter 3, and the remote engine starter 3 transmits the start result to the terminal device 2. The terminal device 2 displays the start result on the screen. This display is, for example, “the engine has started normally”, “the air conditioner has started operation”, or the like.

  After the engine is started, the vehicle-mounted device 4 continuously (for example, periodically) detects vehicle information such as the temperature outside the vehicle compartment, the temperature inside the vehicle cabin, the remaining battery capacity, and the remaining fuel amount to the remote engine starter 3. The remote engine starting device 3 transmits the vehicle information to the terminal device 2. The terminal device 2 displays the vehicle information useful for the user on the screen.

  The processing unit 14 instructs the engine ECU 11 to stop the engine when the idling continuation time received from the remote engine starting device 3 has elapsed after the engine is started. The processing unit 14 also detects the exhaust gas amount of the vehicle by the exhaust gas sensor 27 during the idling operation after starting the engine, and the engine ECU 11 also detects when the accumulated amount reaches the exhaust gas limit amount received from the remote engine starting device 3. To stop the engine.

  The processing unit 14 detects the noise level by the noise sensor 28 even after the engine is started. This noise level includes environmental noise and vehicle noise due to engine start. Therefore, the processing unit 14 obtains vehicle noise by subtracting the noise level detected before starting the engine from the detected noise level. When the obtained vehicle noise level is higher than the received vehicle noise upper limit value, the processing unit 14 instructs the air conditioner ECU 13 to lower the air conditioning capability, or instructs the engine ECU 11 to lower the engine speed. . If the vehicle noise level is still higher than the upper limit value of the vehicle noise, the engine is stopped.

  When the engine 10 is stopped, the in-vehicle device 4 transmits an engine stop notification to the remote engine starter 3, and the remote engine starter 3 transmits the engine stop notification to the terminal device 2. The terminal device 2 displays an engine stop notification on the screen. This display is, for example, “the engine has been stopped because the idling operation has reached 5 minutes”, “the engine has been stopped because the exhaust gas amount during the idling operation has reached the limit value”, and the like.

  According to the present embodiment described above, the remote engine starting device 3 provided in the center receives vehicle information including the current position of the vehicle from the in-vehicle device 4 when receiving an engine start request by remote operation, Based on this, various control parameters that affect the environment are set. The in-vehicle device 4 starts the engine according to the start command signal received from the remote engine starter 3, and controls the idling operation according to the control parameter. With this configuration, the engine can be started and the idling operation thereafter can be performed while reducing the influence on the environment without the user setting the control parameter himself / herself.

  The control means 9 may set at least one of the control parameters indicating the idling duration, the air conditioning capacity in the vehicle interior, the upper limit value of the engine speed, the exhaust gas limit amount that can be discharged, and the upper limit value of the vehicle noise. By setting the idling duration and / or exhaust gas limit amount, the in-vehicle device 4 controls the idling operation time according to the control parameter, so that it conforms to the regulations (laws and regulations) concerning idling applied at the current position of the vehicle. Can do.

  Further, the vehicle noise can be reduced by setting at least one of the air conditioning capability in the passenger compartment, the upper limit value of the engine speed, and the upper limit value of the vehicle noise. The database 6 of the remote engine starter 3 stores map data that distinguishes between regions where vehicle noise due to idling is a problem and regions where it is not a problem. The control means 9 sets the air conditioning capability in the passenger compartment, the upper limit value of the engine speed, or the upper limit value of the vehicle noise according to which region the current position of the vehicle belongs to or according to the detected vehicle noise level. . As a result, the vehicle noise during idling can be reduced only when the vehicle is parked in an area where vehicle noise is a problem, and it is possible to avoid unnecessarily restricting temperature adjustment and warm-up operation in the passenger compartment.

If the obtained vehicle noise level is higher than the upper limit value of the vehicle noise, at least one of the upper limit value of the air conditioning capacity and the engine speed in the passenger compartment is reduced, and the control parameter whose setting has been changed is set. It transmits to the vehicle equipment 4. The in-vehicle device 4 instructs the air conditioner ECU 13 to decrease the air conditioning capacity or instructs the engine ECU 11 to decrease the engine speed according to the control parameter. This feedback control is continuously executed.

  The control means 9 measures the elapsed time from the time when the start result indicating that the engine has started normally from the in-vehicle device 4 is received.
