The invention relates to the technical field of vehicles, and provides an anti-lock control method for a multi-axle vehicle. The method comprises the following steps: S1, acquiring driving state information of wheels, wherein the driving state information comprises a slippage degree, a wheel speed deceleration and a wheel speed vector; s2, under the condition that the slippage degree and the wheel speed deceleration meet the first condition, the ABS adjusting device enters a pressure reduction mode; s3, under the condition that the wheel speed vector meets a second condition, the ABS adjusting device enters a pressure maintaining mode; s4, under the condition that the slippage degree and the wheel speed vector meet a third condition, the ABS adjusting device enters a pressurization mode; and S5, anti-lock control is conducted on the multi-axle vehicle according to the pressure reduction mode, the pressure maintaining mode and the pressure increasing mode. According to the method, the problem that some wheels are easy to lock due to the deviation of empirical values and load distribution in the prior art is solved, the adaptability and the braking safety of the whole vehicle chassis can be greatly improved, and the braking performance of the vehicle is further improved.
本发明涉及车辆技术领域,提供一种多轴车辆防抱死控制方法。该方法包括如下步骤:S1、获取车轮的行驶状态信息,行驶状态信息包括滑移程度、轮速减速度和轮速矢量;S2、在滑移程度和轮速减速度满足第一条件的情况下,ABS调节装置进入减压模式;S3、在轮速矢量满足第二条件的情况下,ABS调节装置进入保压模式;S4、在滑移程度和轮速矢量满足第三条件的情况下,ABS调节装置进入增压模式;S5、根据减压模式、保压模式和增压模式对多轴车辆进行防抱死控制。本发明解决了现有技术中由于经验值和载荷分布的偏差,产生某些车轮易抱死的问题,本发明可以大幅度增加整车底盘的适应性及制动安全性,进而提升了车辆的制动性能。
