The invention relates to the technical field of vehicle control, in particular to a main suspension braking consistency automatic adjusting method and device and a tractor, in the driving process, the temperature of each wheel and the response time of a braking air chamber of each wheel are monitored in real time, and the average air pressure response time of each axle is calculated; the average wheel temperature calculated according to the temperatures of all the wheels serves as the due hub normal temperature when the braking force is evenly distributed, the average temperature of the two corresponding wheels of each axle is compared with the hub normal temperature, whether the braking speed of the axles needs to be adjusted or not is judged according to the temperature critical value, and when adjustment is needed, the braking speed of the axles is adjusted according to the temperature critical value. The controller controls the AEBS relay valve to increase pre-inflation or controls the ABS electromagnetic valve to close the valve element to increase the time, braking advancing and delaying of a main vehicle and braking delaying of a trailer are automatically achieved, main trailer braking is adjusted to be in a balanced state, and braking efficiency distribution is balanced.
本发明涉及车辆控制的技术领域,更具体地,涉及一种主挂制动一致性自动调整方法、装置和牵引车,在行驶过程中实时监测各个车轮的温度和各个车轮的制动气室响应时间,计算出各个车桥的平均气压响应时间,将通过各个车轮的温度计算出的平均轮温作为制动力分配均匀时应有的轮毂正常温度,将各个车桥对应两个车轮的平均温度与轮毂正常温度进行比较,以温度临界值来判断是否需要对车桥的制动快慢进行调整,当需要调整时,通过控制器控制AEBS继动阀增加预充气或控制ABS电磁阀关闭阀芯时间增大,自动实现主车的制动提前和延后以及挂车的制动延后,将主挂制动调节至平衡状态,使制动效能分配均衡。
