ABSTRACT:
Method and device for controlling a motor in a powered seat, wherein one of normal and reverse drive signals from manual or auto switch is detected by a central processing unit, which in turn provides a first period of time defined between one point when the motor starts to drive in normal direction and another point when the normal drive of the motor is stopped, and a second period of time defined between one point when the motor starts to drive in reverse direction and another point when the reverse drive of the motor is stopped, and then, a motor torque switch element brings resistor in electrical connection with the motor terminal, only druing one of those first and second periods of time.
