Abstract: A steering operation control apparatus and steering operation control method capable of suppressing an unintended rotation of a steering wheel with a simple configuration. The steering operation control apparatus includes a steering control portion configured to control a steering actuator configured to operate a steering mechanism configured to drive a steering target wheel, and a reaction force control portion coupled with a steering wheel and configured to control a reaction force actuator configured to provide a reaction force. The reaction force control portion has a function of outputting a stop position maintaining signal required for the reaction force actuator to maintain a present position of the steering wheel to the reaction force actuator when a driver is detected to get out of or get into a vehicle. This aspect just feeds the stop position maintaining signal for maintaining the present position of the steering wheel to the reaction force actuator.
