The invention discloses a vehicle steering-by-wire control method and system, electronic equipment, a vehicle and a medium. The method comprises the following steps: acquiring state information of a driver and a vehicle; the state information comprises a vehicle speed, a steering wheel rotating speed and a vehicle damping coefficient; performing decision processing on the state information through a steer-by-wire active return state decision to obtain an active return state flag bit; if the active return state flag bit is to start active return, determining an active return torque according to the state information; vehicle damping torque is determined according to the vehicle speed, the steering wheel rotating speed and the vehicle damping coefficient; according to the active aligning torque and the vehicle damping torque, active aligning target torque is determined; and driving control is conducted on a motor according to the active return target torque, and vehicle steering is completed. According to the embodiment of the invention, accurate control of vehicle steering can be realized, and the accuracy of active return control is improved. The method can be widely applied to the technical field of intelligent automobiles.

    本发明公开了一种车辆线控转向控制方法、系统、电子设备、车辆及介质。该方法包括:获取驾驶员和车辆的状态信息;所述状态信息包括车辆车速、方向盘转速和车辆阻尼系数;通过线控转向主动回正状态决策对所述状态信息进行决策处理,得到主动回正状态标志位;若所述主动回正状态标志位为开启主动回正,根据状态信息,确定主动回正力矩;根据车辆车速、方向盘转速和车辆阻尼系数,确定车辆阻尼力矩;根据主动回正力矩和所述车辆阻尼力矩,确定主动回正目标转矩;根据所述主动回正目标转矩对电机进行驱动控制,完成车辆转向。本申请实施例能够实现对车辆转向的精准控制,提升主动回正控制的准确度。本方法可以广泛应用于智能汽车技术领域。
