STEERING CONTROL DEVICE AND STEERING CONTROL METHOD

摘要

To improve silence in a vehicle interior space in an idle reduction state, a vehicle includes an idle reduction function of stopping the idling of the engine and restarting the engine when the vehicle starts moving. When the engine is in a working state, the clutch is disengaged and control of driving of a turning actuator is performed, and when the engine is in a stop state, the clutch is engaged and the control of driving of the turning actuator is stopped. Furthermore, a disconnected state of the clutch is maintained when idling of the engine is stopped by the idle reduction function.
