  In step S1, the vehicle ECU 2 determines whether the temperature in the vehicle can be lowered more quickly if ventilation (introducing the outside air into the vehicle) is performed based on the temperature in the vehicle, the outside air temperature, the set temperature, and the like. Then, it transfers to step S2, performs the said crime prevention external air introduction process or the said normal external air introduction process, and will complete | finish (end) if it determines with it not being possible.

  In step S <b> 2, the vehicle ECU 2 drives the opening / closing body driving device 3 so that the window glass 7 is in the preset open position, and the process proceeds to step S <b> 3. The preset open position is set at an intermediate position of the open / close section of the window glass 7.

  In step S3, the vehicle ECU 2 determines whether or not a person has been detected by the human sensor 5, and if it is determined that no person has been detected, the process proceeds to step S4 and will be described later if it is determined that a person has been detected. The process proceeds to step S5.

  In step S4, the vehicle ECU 2 determines whether or not to end the ventilation. When it is determined that the ventilation is to be ended, the vehicle ECU 2 proceeds to step S6, and when it is determined that the ventilation is not to be ended, the vehicle ECU 2 returns to step S3. In the present embodiment, the vehicle ECU 2 determines whether or not ventilation (introducing outside air into the vehicle) can quickly reduce the temperature in the vehicle from the temperature in the vehicle, the outside air temperature, the set temperature, and the like. If it is determined that it cannot be performed, it is determined that ventilation is to be terminated. In addition, the vehicle ECU 2 determines that the ventilation is to be ended if any stop condition is satisfied, for example, a signal to stop the engine is input from the remote controller 8.

  On the other hand, in step S5, the vehicle ECU 2 drives the opening / closing body driving device 3 so that the window glass 7 is closed by a preset amount, and proceeds to step S7. Note that the preset amount at this time is set so that the window glass 7 does not reach the fully closed position.

  In step S7, the vehicle ECU 2 drives the opening / closing body driving device 3 so that the window glass 7 is opened by a preset amount, and the process proceeds to step S4. Note that the preset amount at this time is set so that the window glass 7 is at the preset open position.

  If the vehicle ECU 2 determines that the ventilation is finished in step S4, in step S6, the vehicle ECU 2 drives the opening / closing body drive device 3 so that the window glass 7 stops at the fully closed position, and the process ends (end).

Next, the operation of the above-described vehicle interior temperature control system will be described.
For example, when the air conditioner 4 is in cooling operation when the engine of the vehicle 1 is stopped, when the owner of the vehicle 1 operates the operation switch of the remote controller 8 from home, a control signal is output (transmitted) from the remote controller 8. Then, the engine is started by the vehicle ECU 2 to which the control signal is input, and the cooling operation of the air conditioner device 4 is started.
