The invention discloses a vehicle control method and a vehicle. The vehicle control method comprises the steps that the first wheel speed of a left front wheel, the second wheel speed of a right front wheel, the third wheel speed of a left rear wheel, the fourth wheel speed of a right rear wheel and the transmission shaft rotating speed of a transmission shaft are obtained; obtaining a first vehicle speed of the first axle according to the first wheel speed and the second wheel speed; obtaining a second vehicle speed of the third axle according to the third wheel speed and the fourth wheel speed; the average speed between the second axle and the third axle is obtained according to the transmission shaft rotating speed and the rear axle speed ratio; the slipping state of the vehicle is determined according to the first wheel speed, the second wheel speed, the third wheel speed, the fourth wheel speed, the first vehicle speed, the second vehicle speed and/or the average vehicle speed; the vehicle is controlled to execute the differential control strategy according to the slipping state, the vehicle control method can solve the problem of slipping between axles or between tires, the utilization rate of driving force of the vehicle is increased, tire abrasion is reduced, and combination and separation of a differential lock are controlled through an electromagnetic valve.
本发明公开了一种车辆控制方法和车辆,所述车辆控制方法包括:获取左前轮的第一轮速、右前轮的第二轮速、左后轮的第三轮速、右后轮的第四轮速以及传动轴的传动轴转速;根据第一轮速和第二轮速获得第一车轴的第一车速;根据第三轮速和第四轮速获得第三车轴的第二车速;根据传动轴转速和后桥速比获得第二车轴与第三车轴之间的平均车速;根据第一轮速、第二轮速、第三轮速、第四轮速、第一车速、第二车速和/或平均车速确定车辆的打滑状态;根据打滑状态控制车辆执行差速控制策略,采用该车辆控制方法可以解决车轴间或轮胎间发生打滑的问题,增加车辆的驱动力的利用率并减少轮胎磨损,并且通过电磁阀控制差速锁的结合和分离。
