Abstract: A first circuit energizes a steering assist actuator to electrically assist steering of a driver. A second circuit is provided in a same housing as the first circuit and energizes a positional actuator to move a steering position. A controller operates the first and second circuits to control operations of the steering assist actuator and the positional actuator. The controller changes a priority between the first circuit and the second circuit in a start period, in which the steering control device is started, a normal operation period, in which the steering control device is operated normally, and a stop period, in which the steering control device is stopped. The priority includes at least one of an order of operating the first circuit and the second circuit, output allocation between the first circuit and the second circuit, and output magnitude between the first circuit and the second circuit.
