  • Publication number: 20240140525
    Abstract: In a detection method for detecting an end position of a mechanism portion of a turning device, detection of a limit position of a steering angle in a direction of a torque value is started when the torque value of the mechanism portion loaded by at least one of a drive force from an actuator and steering torque to the mechanism portion exceeds a first threshold. The limit position continues to be detected by storing a peak value of the steering angle in the mechanism portion as the limit position while the torque value of the mechanism portion is between the first threshold and a second threshold. The stored limit position is regarded as the end position indicated by the torque value when the torque value of the mechanism portion exceeds the second threshold.
