The invention discloses a steering-by-wire system road feeling compensation method suitable for an uneven road surface. An information acquisition module, a steady-state torque calculation module, a dynamic torque compensation module and a road feeling feedback torque calculation module are included. The information acquisition module acquires road adhesion coefficients and uneven road information and sends the road adhesion coefficients and the uneven road information to the dynamic torque compensation module, the steady-state torque calculation module calculates steady-state torque, the dynamic torque compensation module calculates dynamic torque, and the road feeling feedback torque calculation module calculates final road feeling feedback torque. The road feeling feedback torque is designed to be in a form of superposition of the steady-state torque and the dynamic torque, the steady-state torque is used for providing vehicle state information and road surface attachment conditions for a driver, the dynamic torque is used for providing uneven road surface information for the driver, and therefore comprehensive road feeling information is provided for the driver; and the safety of driving on an uneven road section can be improved.
本发明公开了一种适用于不平路面的线控转向系统路感补偿方法,包括信息获取模块、稳态力矩计算模块、动态力矩补偿模块和路感反馈力矩计算模块。信息获取模块获取路面附着系数和不平路面信息并发送给动态力矩补偿模块,稳态力矩计算模块计算稳态力矩,动态力矩补偿模块计算动态力矩,路感反馈力矩计算模块计算最终的路感反馈力矩。本发明将路感反馈力矩设计成稳态力矩和动态力矩叠加的形式,使用稳态力矩为驾驶员提供车辆状态信息和路面附着情况,通过动态力矩为驾驶员提供不平路面信息,从而为驾驶员提供全面的路感信息,有助于提高在不平路段行驶时的安全性。
