An electronic steering apparatus of a vehicle may include: a reaction torque generation unit configured to generate a command reaction torque based on a steering condition of a driver; and a reaction torque control unit configured to receive the rack force and the vehicle speed, tune the road sensitivity according to the vehicle speed, set a road sensitivity torque by applying a gain based on the reaction sensitivity, reflect the road sensitivity torque in a command reaction torque, and output a final reaction torque to the driving motor. An electronic steering apparatus of a vehicle of the present invention may tune a road-dependent reaction sensitivity by applying a band-pass filter to a rack force estimate according to a vehicle speed, thereby providing a driver with a reaction feeling based on road characteristics.
一种车辆的电子转向装置,可包括:反应扭矩生成单元,配置为基于驾驶员的转向条件来生成指令反应扭矩;以及反应扭矩控制单元,配置为接收齿条力和车辆速度,根据车辆速度调谐道路灵敏度,通过施加基于反应灵敏度的增益来设置道路灵敏扭矩,将道路灵敏扭矩反映在指令反应扭矩中,并向驱动电机输出最终反应扭矩。本发明的车辆的电子转向装置可以根据车辆速度通过向齿条力估计值施加带通滤波器来调谐取决于道路的反应灵敏度,从而给驾驶员提供基于道路特性的反应感觉。
