1. A steering control device for controlling electricity supply to a turning motor generating a turning force for turning a turning wheel of a vehicle and that (i) calculates a target angle of a shaft depending on a steering state of a steering wheel and (ii) executes a feedback control to cause an actual angle of the shaft to follow the target angle, the shaft rotating in conjunction with a turning operation of the turning wheel, which is isolated from dynamic power transmission with the steering wheel,
the steering control device comprising a memory and a processor programmed to execute:
a first processing to alter the target angle independently of the steering state of the steering wheel; and
a second processing (i) to calculate a turning state amount for a guide monitor function by reducing or removing an influence of an alteration of the target angle by the first processing on the actual angle of the shaft and (ii) to display the calculated turning state amount on a display of the vehicle to assist a driver during traveling of the vehicle.
