  First, when the mode selection switch 31 is operated by the driver under the standby state in step S1 and the operation mode is selected in step S2, one of the opening / closing switches 22a to 22d and 27b to 27d is turned on in step S3. It is determined whether it has been turned on, that is, whether it has been operated. If it is determined in step S3 that any one of the opening / closing switches 22a to 22d and 27b to 27d has been operated, it is determined in step S4 whether the operated opening / closing switch is a driver seat, that is, the DR opening / closing switch 22a. If it is determined that the DR open / close switch 22a has been operated, it is determined in step S5 whether or not the power window motor 14a in the driver's seat is operating.

  On the other hand, if it is determined in step S4 that the open / close switch operated in step S3 is an open / close switch other than the driver's seat, whether or not the operation mode selected by the mode selection switch 31 in step S6 is the lock mode. If it is determined that the lock mode is selected, the routine returns to step S1. If it is determined that the lock mode is not selected, the routine proceeds to step S5, and in step S5, the power window motor 14b other than the driver seat is selected. , 14c, 14d are determined.

  In the following step S5, it is determined whether or not any of the power window motors 14a to 14d is operating when the open / close switch is operated in step S3, and any of the power window motors 14a to 14d is operating. If there is, the operation of the power window motors 14a to 14d is stopped in step S7, and the routine is returned. That is, when the open / close switch is operated while the power window motors 14a to 14d are in operation, the operation is determined to be a stop operation, and the operation of the power window motors 14a to 14d is stopped.

  On the other hand, if the power window motors 14a to 14d are not in operation in step S5, the process proceeds to step S8, and it is determined whether or not the open / close switch operated in step S3 is for the driver's seat. If it is determined in step S8 that the power window motor 14a is for the driver's seat, it is determined in step S9 whether or not the auto switch 24 is turned on, that is, whether or not the auto switch 24 is activated. In step S10, the driver's seat power window motor 14a automatically operates. On the other hand, if it is determined in step S9 that the auto switch 24 is not operated, the driver seat power window motor 14a is determined in step S11. 14a is manually operated.
