Claim 16:
17. A control device that controls a torque transmission device, the torque transmission device including an actuator that operates by being energized and a torque transmission portion that is switched to a transmission state or a non-transmission state by the actuator operating, and configured to transmit a torque between a first transmission portion and a second transmission portion when the torque transmission portion is in the transmission state, the control device comprising a processor configured to:
calculate a target transmission torque that is a torque to be transmitted between the first transmission portion and the second transmission portion;
determine that an operating mode is an engagement mode when the target transmission torque increases over time, determine that the operating mode is a release mode when the target transmission torque decreases over time, and determine that the operating mode is a steady mode when the target transmission torque does not change over time;
control the actuator based on the operating mode determined,
perform feedback-control of the actuator based on the target transmission torque,
set a gain used for the feedback-control,
calculate a duty based on the gain,
output the duty calculated as an output duty,
control energization of the actuator based on the output duty, and
shift to a control stop mode that causes the processor to stop the feedback-control of the actuator when a predetermined stop condition is satisfied in a case where the processor determines that the operating mode is the steady mode, and
store an integral calculation value in the feedback-control immediately before the processor stops the feedback-control of the actuator when shifting to the control stop mode, and then restarts the processor performing the feedback-control of the actuator by using the integral calculation value stored when a predetermined restart condition is satisfied.
