| 摘 要： | 文章利用trucksim重型汽车动力学仿真软件,对六轮双轴重型汽车在低附着路面左右车轮附着系数不一致情况下进行紧急制动的行驶工况进行了仿真研究。研究结果表明在低附着路面进行紧急制动时,对制动轮进行制动压力控制,有ABS控制的重型汽车比没有ABS控制的重型汽车具有更好地行驶稳定性。但在低附着路面上,有ABS控制的重型汽车比没有ABS控制的重型汽车的制动距离增加了很多,这对重型汽车的行车安全性非常不利。

| Abstract: | In this paper,the dynamic simulation software trucksim is used to simulate the emergency braking of six wheel double axle heavy truck under the condition of inconsistent adhesion coefficient of left and right wheels on low adhesion road.The results show that the heavy-duty vehicle with ABS control has better driving stability than the heavy-duty vehicle without ABS control.But on the low adhesion road,the braking distance of heavy vehicles with ABS control is much longer than that of heavy vehicles without ABS control,which is very unfavorable to the driving safety of heavy vehicles. |
