Abstract
A correct commutation is realized even if a communication error occurs due to a change in an actuator drive current. An electronic control unit that includes a communication section outputting a control signal and that can transmit the control signal to an actuator connected to the electronic control unit via a power line, includes an actuator operation detection section. When the actuator operation detection section detects an actuator operation, the communication section retransmits the control signal at timing of detecting the actuator operation.
