The invention provides a heavy-duty commercial vehicle steering driving hand feeling self-adjusting method and system, and the method comprises a steering load arbitration adjustment step: obtaining a current torque value mean value when the steering of a driver meets a steering compensation condition; the current torque value mean value is compared with a set no-load torque mean value and a set full-load torque mean value to obtain a steering load compensation coefficient; the driver torque corresponding to the current vehicle speed is obtained according to the set basic assistance curve, the product of the driver torque and the steering load compensation coefficient serves as basic assistance for driving hand feeling adjustment, the steering force of the driver is compensated mainly according to the whole vehicle state information, and the characteristics of low-speed steering sensitivity and high-speed steering stability are achieved.
本发明提出一种重型商用车转向驾驶手感自调整方法及系统,方法包括转向载重仲裁调整步骤:当驾驶员转向满足转向补偿条件时,获取当前扭矩值均值;利用当前扭矩值均值与设定的空载扭矩均值及满载扭矩值均值进行比较得到转向载重补偿系数;根据设定基础助力曲线获取当前车速对应的驾驶员扭矩,将驾驶员扭矩与转向载重补偿系数的乘积作为驾驶手感调整的基础助力,本发明主要依据整车状态信息对驾驶员转向力进行补偿,实现低速转向灵敏,高速转向稳重特性。
