A steering control device for a drive-by-wire vehicle is used for outputting a vehicle steering control signal to the drive-by-wire vehicle, and the drive-by-wire vehicle generates a vehicle steering feedback signal corresponding to the vehicle steering control signal. The steering load driving unit is used for feeding back a steering feeling to an operator. The response identification unit obtains a steering angle command, a steering angle feedback and a vehicle speed according to the vehicle steering control signal and the vehicle steering feedback signal, and performs 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, the vehicle speed, the steering angle gain and the steering angle phase are input into a steering system model to simulate a steering load of the drive-by-wire vehicle, and the steering load is input into a steering load driving unit to generate a steering feeling.
一种用于线控车辆的转向控制装置,用以输出一车辆转向控制信号至线控车辆,线控车辆对应车辆转向控制信号产生一车辆转向反馈信号。转向负载驱动单元用以反馈一转向感受至一操作者。响应鉴别单元根据车辆转向控制信号及车辆转向反馈信号取得一转向角命令、一转向角反馈以及一车辆速度,并进行傅里叶转换以取得一转向角增益及一转向角相位,以鉴别出线控车辆的一响应特性。将转向角反馈、车辆速度、转向角增益及转向角相位输入至一转向系统模型中,以模拟线控车辆的一转向负载,且转向负载输入至转向负载驱动单元中,以生成转向感受。
