Steering control device

A steering control device comprising a control circuit configured to control driving of a reaction force motor that generates steering reaction force that is given to a steering wheel, dynamic power transmission being not performed between the steering wheel and a turning wheel of a vehicle, wherein:

• the control circuit is configured to request a vehicle control device to stop operation of a powertrain in a case where a vehicle electric power source has been turned on and where exchange of information has been performed with the vehicle control device so as not to follow a preset pattern, the vehicle control device controlling traveling of the vehicle, the powertrain including a traveling drive source of the vehicle;
• the control circuit is configured to determine whether it is necessary to request the vehicle control device to stop start-up of the powertrain of the vehicle by determining whether the vehicle is in a state that is capable of traveling by the dynamic power transmission;
• and
• the control circuit is configured to not request the vehicle control device to stop the operation of the powertrain, even when the vehicle electric power source has been turned on and the exchange of the information has been performed with the vehicle control device so as not to follow the preset pattern, in a case where the control circuit has determined that it is not necessary to stop the start-up of the powertrain based on a result of the determination on whether the vehicle is in the state that is capable of traveling by the dynamic power transmission.
