摘要： When an operation of lowering window glass is conducted to attain a full-opened state and a lock current flows, a lowering operation is invalidated, thereby preventing the lock current from continuously flowing. When a raising operation is conducted under the full-opened state, a power window motor is operated in a direction of closing the window glass, and the in validating state is canceled. In the case where, before the full-closed state is attained, a foreign object is caught and the lock current flows, the same as above is conducted. In a raising operation of closing the window glass, the raising operation under the full-closed state is invalidated, thereby preventing the lock current from continuously flowing. When a lowering operation is conducted under the full-closed state, the power window motor is operated in the direction of opening the window glass, and the invalidating state is canceled.

摘要： A device for detecting failure of a field effect transistor (FET) includes a first FET1 connected in series with a motor M between a power source terminal and ground, a motor control unit 11 for on/off controlling a voltage to be applied to said motor to set normal/reverse operation and stopping of said motor, a gate control unit for on/off controlling a gate voltage to be applied to said FET to control driving of said motor, a voltage applying means VB, R1 for applying a positive voltage at a prescribed voltage level to the current input terminal of the FET; a voltage detecting unit CMP1 for detecting the voltage level of the positive voltage thus applied when said gate voltage is off; and a failure detecting unit 14 for detecting short-circuiting failure of the FET on the basis of a change in the voltage level detected by said voltage detecting unit when said gate voltage is off while said motor stops. In this configuration, failure of the FET for controlling driving of the motor can be detected both when the motor stops and operates.
