The invention relates to a control method and device for a multi-axle distributed electric drive axle in a vehicle, computer equipment and a storage medium, and the method comprises the steps: recognizing a workable drive axle in the multi-axle distributed electric drive axle, obtaining the priority of the workable drive axle according to the accumulated mileage of the vehicle and a preset axle priority adjustment rule, obtaining the total request torque of the vehicle and the motor rotating speed of the workable drive axle, and obtaining the distribution torque corresponding to the workable drive axle according to the total request torque, the motor rotating speed of the workable drive axle and the priority of the workable drive axle, so that the output torque of the workable drive axle is controlled. In the whole process, the priority of the working drive axle can be changed according to the driving mileage of the vehicle, it is guaranteed that a transmission system and tires are evenly abraded, and the control over the multi-axle distributed electric drive axle in the vehicle can be reasonably and effectively achieved.
本申请涉及一种车辆中多桥分布式电驱动桥的控制方法、装置、计算机设备和存储介质,其中,方法包括:识别多桥分布式电驱动桥中可工作驱动桥,根据车辆累计行驶里程以及预设车桥优先级调整规则,获取可工作驱动桥的优先级,获取车辆的总请求扭矩以及可工作驱动桥的电机转速,并根据总请求扭矩、可工作驱动桥的电机转速以及可工作驱动桥的优先级,获取可工作驱动桥对应的分配扭矩,以控制可工作驱动桥的输出扭矩。整个过程中,能根据车辆行驶里程,改变可工作驱动桥的优先级,保证传动系统和轮胎磨损均匀,能够合理且有效实现对车辆中多桥分布式电驱动桥的控制。
