とを特徴とする舵角修正装置。 A steering wheel angle sensor that detects the steering angle of the steering wheel, an electric actuator for steering operation that operates based on the detection signal of the steering wheel angle sensor, a yaw rate gyroscope that detects the turning acceleration of the vehicle, and a vehicle speed that detects the vehicle speed. A sensor, a steering angle sensor that detects the steering angle of the vehicle, and a steering wheel angle sensor that outputs detection signals as actuation signals for an electric actuator for steering operation, and calculates a reference turning acceleration based on the detected values of the vehicle speed sensor and the steering angle sensor. The calculated reference acceleration is compared with the actual turning acceleration detected by the yaw rate gyroscope, and the road surface condition is determined based on the comparison result, and the target rudder suitable for the road surface condition is determined based on the actual turning acceleration and the vehicle speed detected by the vehicle speed sensor. The steering angle is calculated, the target steering angle is compared with the actual steering angle detected by the steering angle sensor, and if the actual steering angle exceeds the target steering angle, a signal is sent to the steering control electric motor to return the excess steering angle. A steering angle correction device comprising: an arithmetic and control device that outputs output to an actuator.
