Control device for vehicle

A control device for a steer-by-wire vehicle,

• the steer-by-wire vehicle comprising:
• a power supply device;
• and
• actuators operated by electric power supplied from the power supply device,
• the actuators comprising:
• a turning actuator configured to turn a wheel of the steer-by-wire vehicle;
• and
• a reaction actuator configured to apply a reaction torque to a steering wheel of the steer-by-wire vehicle,
• the power supply device comprising:
• a main power supply;
• and
• a backup power supply configured to supply the electric power to the actuators when an abnormality occurs in the main power supply,
• the control device being configured to execute:
• turning control that turns the wheel by controlling the turning actuator according to a steering operation of the steering wheel;
• reaction torque control that applies the reaction torque to the steering wheel by controlling the reaction actuator according to the steering operation of the steering wheel when the electric power is supplied from the main power supply to the actuators;
• and
• power suppression processing that stops control of the reaction actuator when the electric power is supplied from the backup power supply to the actuators.
