PURPOSE:To prevent the damage of a motor by stopping the driving of a window glass opening/closing motor in the case of the 'on' period of a window glass opening/closing switch becomes the specified value or more. CONSTITUTION:When a switch on/off judging part 6 judges a switch 1-1 to be on, a timer 7 starts clocking the time, and a motor control part 4 drives a motor 2-1, and when the judging part 6 judges the switch 1-1 to be off, the control part 4 stops the motor 2-1. When the on state of the switch 1-1 continues, a switch abnormality judging part 8 judges whether or not the clocking time of the timer 7 is the specified value or more. In the case of being the specified value or more, the control part 4 stops the driving of the motor 2-1, and an LED control part 5 blinks an LED 3-1 and emits an alarm. Further when an occupant turns the switch 1-1 off, the control part 5 changes the LED 3-1 into the continuously lighted state. The same control is applied to a switch 1-2. The motor is thereby kept from being overloaded so as to prevent overheat, damage, and the like. |
