Patent ID: 7617034

Claim:
A control apparatus for controlling an opening/closing body that opens and closes an opening in a vehicle body by moving with respect to the vehicle body, the control apparatus comprising: a drive motor that switches between a low-speed mode for moving the opening/closing body with a relatively high torque at a low velocity and a high-speed mode for moving the opening/closing body with a relatively low torque at a high velocity; a position sensor that detects the position of the opening/closing body with respect to the vehicle body; a velocity sensor that detects the velocity of the opening/closing body; and a control unit that compares the velocity of the opening/closing body with a threshold velocity when the opening/closing body 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, wherein the control unit sets a target velocity of the opening/closing body to a high target velocity for moving the opening/closing body in the high-speed mode, and the control unit sets a target velocity of the opening/closing body to a low target velocity for moving the opening/closing body in the low-speed mode.
