The invention relates to the technical field of steering systems, in particular to a method for restraining steering wheel shaking caused by steering wheel end shaking. A method for restraining steering wheel shaking caused by steering wheel end shaking comprises a steering wheel torque sensor, an EPS controller, an ESP controller, a motor and a wheel speed sensor, and the ESP controller transmits a wheel speed signal detected by the wheel speed sensor to the EPS controller through a CAN bus. Compared with the prior art, the method for restraining steering wheel shaking caused by steering wheel end shaking can accurately recognize steering wheel shaking caused by wheel dynamic unbalance, reverse torque is calculated through a self-adaptive algorithm, shaking is restrained after the reverse torque is output by an EPS motor, the control ability and comfort of a driver to a vehicle are improved, and the steering wheel shaking caused by steering wheel end shaking is restrained. And the influence of jitter on the service life of the EPS system is avoided.
本发明涉及转向系统技术领域,具体地说是一种抑制由转向轮端抖动引起的方向盘抖动的方法。一种抑制由转向轮端抖动引起的方向盘抖动的方法,包括方向盘扭矩传感器、EPS控制器、ESP控制器、电机、轮速传感器,ESP控制器将轮速传感器检测到的轮速信号通过CAN总线传递给EPS控制器。同现有技术相比,提供一种抑制由转向轮端抖动引起的方向盘抖动的方法,能准确识别由车轮动不平衡引起的方向盘抖动,并通过自适应算法计算反向力矩,由EPS电机输出后对抖动形成抑制,既提高了驾驶员对车辆的操控能力和舒适性,又避免了抖动对EPS系统的寿命产生影响。
