When 1 minute has passed in step S37, the blowing and swinging are stopped in step S38, and the blowing amount set in steps S26 to S28 and the swinging state set in steps S29 to S36 are stored.

In step S39, it is judged whether or not the operation stop signal from the air conditioner 13 is received. If the operation stop signal of the air conditioner 13 is not received, after the sleep operation mode is selected in step S40. It is determined whether or not a predetermined time, 8 hours in the present embodiment, has elapsed. If 8 hours have elapsed, the sleep mode is canceled in step S41, and the process proceeds to the main routine. Therefore, it is possible to eliminate the inconvenience of forgetting to cancel the sleep mode and operating the vehicle in the absence of anyone.

When the operation stop signal of the air conditioner 13 is received in step S39, the process proceeds to step S42. In step S42, the difference T between the air volume number T2 set in the air volume memory in steps S26 to S28 and the air volume number T1 calculated this time is calculated, and in step S43 the air volume number T1 is set to T2. In step S44, the air volume memory stores the air volume number stored in the air volume memory in step S42.
The air volume number added with the air volume difference T calculated in step S45 is set, and the air flow is started with the air volume number of the air volume memory calculated in step S44 in step S45, and is set in step S29 to step S36 in step S46. Oscillate.

In step S47, it is judged whether or not two hours have passed in the present embodiment for a certain period of time after receiving the operation stop signal of the air conditioner 13, and if two hours have passed, the operation is stopped in step S48. Then, shift to the main routine. If two hours have not elapsed in step S47, it is determined in step S49 whether or not the signal from the air conditioner 13 has been received. When the environmental information signal from the air conditioner 13 is received, the process proceeds to step S39. , Step S39
Through step S49, air is blown at an air volume corresponding to the room temperature detected by the air conditioner 13.

Although the environmental information signal from the air conditioner 13 is room temperature in the present embodiment, it may be a discomfort index calculated from the room temperature and humidity, or other environmental information.

In this embodiment, the operation is started immediately after receiving the operation stop signal from the air conditioner 13, but when the temperature rises from the temperature when the air conditioner 13 is stopped, a predetermined temperature rises. It may be configured to start the operation.
