Control apparatus controlling opening and closing member for vehicle

A control apparatus controlling an opening and closing member for a vehicle, the control apparatus comprising:

• an electronic control unit (ECU) configured to:
• output a motor control signal, the motor control signal being for supplying driving electric power to a motor;
• set an advance angle value, the advance angle value being for advancing a phase of the motor control signal when an assist opening and closing operation is performed as compared to when an automatic opening and closing operation is performed;
• and
• perform the automatic opening and closing operation, which causes the opening and closing member of the vehicle to automatically open and close with driving force of the motor, and the assist opening and closing operation, which causes the opening and closing member to open and close in such a manner that the driving force of the motor assists a manual operation force applied to the opening and closing member,
• wherein, at the assist opening and closing operation, in a case where a moving speed of the opening and closing member is large, the ECU is configured to set the advance angle value to be larger as compared to a case where the moving speed of the opening and closing member is small.
