When the driving rear axle assembly is used, the rotating speed and torque of motors of two driving assemblies are controlled through a controller, and the moving working conditions of a left tire and a right tire are adjusted. When a vehicle runs in a straight line, the two motors output power to tires through the transmission shaft system, and the two motors keep synchronous output. When turning is needed, the controller controls different rotating speeds and torque output of the two motors, monitors the difference between the left rotating speed and the right rotating speed in real time, adjusts the controlled rotating speed range, and forms closed-loop control. When the whole vehicle needs to achieve the tank steering function, one motor is locked, the other motor outputs power, and the tank steering function of the whole vehicle is achieved. The driving rear axle assembly is provided with the half axle assembly, the double motors and the double speed reducers, a differential assembly structure in the prior art is omitted, and therefore the cost of the whole vehicle is reduced, the left tire and the right tire are controlled through the controller, and driving coordination is achieved. The invention further discloses a driving control method.

    本发明公开了一种驱动后桥总成,使用时,通过控制器控制两个驱动组件的电机的转速和扭矩,调节左右两个轮胎的移动工况。车辆直线行驶时,两个电机分别通过传动轴系,将动力输出至轮胎,两个电机保持同步输出;需要转弯时,控制器控制两个电机的不同转速和扭矩输出,并实时监控左右转速差,调整控制的转速范围,形成闭环控制;当整车需要实现坦克转向功能时,其中一个电机锁死,另一个电机输出提供动力,实现整车坦克转向功能。驱动后桥总成通过设置半轴总成、双电机和双减速器,取消了现有技术中的差速器总成结构,从而降低了整车成本,通过控制器对左右两个轮胎分别控制,实现了驱动协调。本发明还公开了一种驱动控制方法。
