  • Publication number: 20220204077
    Abstract: A steering control device is provided to output a vehicle steering control signal to a wire-controlled vehicle. The wire-controlled vehicle generates a vehicle steering feedback signal corresponding to the vehicle steering control signal. The steering load drive unit is configured to feedback a steering feel to an operator. The response discrimination unit obtains a steering angle command, a steering angle feedback, and a vehicle velocity according to the vehicle steering control signal and the feedback signal, and performs a Fourier transform to obtain a steering angle gain and a steering angle phase to identify a response characteristic of the wire-controlled vehicle. The steering angle feedback, vehicle velocity, steering angle gain, and steering angle phase are inputted into a steering system model to simulate a steering load of the wire-controlled vehicle, and the steering load is inputted to the steering load drive unit to generate the steering feel.
