The invention discloses a steer-by-wire uneven road surface road feeling feedback device suitable for different drivers. The device comprises an information acquisition module, a comfort degree calculation module, an information amount calculation module, a weight distribution module and a road feeling feedback torque calculation module. The comfort calculation module is used for calculating an uncomfortable factor for measuring the uncomfortable degree of the driver caused by the road feeling feedback torque; the information amount calculation module calculates an information amount factor used for measuring the size of the uneven road surface type information amount carried by the road feel feedback torque; the weight distribution module is used for determining specific numerical values of an uncomfortable factor and an information quantity factor corresponding to the road feeling feedback torque; and the road feeling feedback torque calculation module calculates a road feeling feedback torque meeting the numerical values of the uncomfortable factor and the information quantity factor based on the rack force, so that unbearable uncomfortable feeling is not caused to a driver under the condition that the road feeling information of an uneven road surface is reserved, and the requirements of different drivers on the comfort degree are met.
本发明公开了一种适用于不同驾驶员的线控转向不平路面路感反馈装置,本装置包括信息获取模块、舒适度计算模块、信息量计算模块、权重分配模块和路感反馈力矩计算模块。舒适度计算模块计算用于衡量路感反馈力矩对驾驶员造成的不舒适程度的不舒适因子;信息量计算模块计算用于衡量路感反馈力矩所携带的不平路面类型信息量大小的信息量因子;权重分配模块用于确定路感反馈力矩对应的不舒适因子和信息量因子的具体数值;路感反馈力矩计算模块基于齿条力计算满足不舒适因子和信息量因子数值大小的路感反馈力矩,实现在保留不平路面路感信息的情况下,不给驾驶员造成无法忍受的不舒适感,并且适应不同驾驶员对舒适程度的要求。
