摘要: 为了避免由于路面附着系数过低或突变而导致的车辆摆尾等事故,可为车辆增设路面附着系数在线辨识模块,提升车辆主动安全性能。建立路面附着系数辨识模型,基于递推最小二乘法,实现路面附着系数的在线辨识;考虑路面附着系数的影响,提出差动制动控制策略;通过Simulink/Carsim联合仿真,验证所提出差动制动控制策略的优越性。结果表明,修正后的控制策略提高了车辆差动制动性能,提高了车辆的行驶稳定性。

关键词: 车辆工程, 附着系数, 差动制动, 控制策略, 行驶稳定性

Abstract: In order to avoid the resulting wagging tail and other accidents that caused by the low adhesion or variation of the road surface, an online identification module for the tire-road friction can be added to the vehicle to improve the vehicle active safety performance. An online identification module for tire-road friction was designed based on the recursive least squares method. And then differential braking strategies were analyzed based on the tire-road friction. The proposed strategy was validated by Simulink/Carsim co-simulation, and the results show that the modified strategy improves the control accuracy of differential braking and driving stability .

Key words: vehicle engineering, tire-road friction, differential braking, control strategy, driving stability
