Abstract

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.

Description

Technical field [0001] The present application relates to the field of intelligent control technology, and in particular, to a control method, apparatus, computer device, and storage medium of a multi-bridge distributed electric drive bridge in a vehicle. Background technique [0002] With the development of economic level, more and more vehicles are now in actual production and life applications, bringing great convenience to people. With the improvement of life demand, there are already many vehicles that have developed towards the direction of large-scale, and this trend is the most obvious truck, for example, the existing large traction semi-trailer. Specifically, the traction semi-trailer is the main transportation of my country's goods transport. With the growth of my country's logistics demand, more and more running trucks running on the expressway will bring huge pressure to environmental protection while bringing energy saving. The demand of the row, the new energy bandw...
