ABSTRACT:
A control unit controls a sliding door that opens and closes an opening in a vehicle body by moving with respect to the vehicle body. The control unit includes a drive motor that switches between a low-speed mode for moving the sliding door with a relatively high torque at a low velocity and a high-speed mode for moving the sliding door with a relatively low torque at a high velocity, a rotary sensor that detects the position and velocity of the sliding door with respect to the vehicle body, and a control unit that compares the velocity of the sliding door with a threshold velocity when the sliding door reaches a first predetermined position and sets the drive motor to one of the low-speed mode and the high-speed mode depending on the result of comparison.
