基于逻辑门限值的汽车ABS控制策略与试验研究
Study on control strategy and experiment of automobile ABS based on logic threshold value
摘要
Abstract
The ABS logic threshold control strategy considering different axle load of front and rear axle as well as braking axle weight transfer is studied.The control of wheel sliding rate is as the main control objective and the control of the wheel angular acceleration is as the auxiliary control objective.The different optimal slip rate range of front and rear wheels are determined through the simulation experiments.Vehicle braking performance is improved in the low adhesion and split road by using the control mode,in which the high brake pressure of the front axle is selected and the low brake pressure of the rear axle is selected.Writing the control strategy program and the control strategy is verified based on driving simulator hardware in loop brake test bench in emergency braking condition of low adhesion and split road.The results show that the control strategy has a good real-time performance and shorten the braking distance,improves the directional stability of the car when braking.关键词
