Drive anti-skid control method and vehicle

Abstract

The invention provides a drive anti-skid control method and a vehicle. The drive anti-skid control method includes the steps that the current control stage of a vehicle in a drive anti-skid state is determined; the current road adhesion coefficient of the vehicle is determined; according to the current control stage and the current road adhesion coefficient, the maximum torque permitted by the road surface is determined; and according to the maximum torque permitted by the road surface, the drive anti-skid required torque is output, wherein the drive anti-skid required torque is used for conducting drive anti-skid on the vehicle. By the adoption of the provided drive anti-skid control method, the response speed can be increased, robustness is enhanced, and control accuracy can be improved.

Description

technical field

[0001] The present application relates to the field of automobiles, and more particularly, to a driving slip control method and a vehicle. Background technique

[0002] The four-wheel independent drive electric vehicle has four independently controllable power sources, which can quickly and accurately control the driving force according to the current vehicle and road conditions, and has become the development trend of the next generation of electric vehicles.

[0003] The national 973 / 863 plan has listed the key technology of four-wheel independent drive, especially the dynamic control technology (ABS / ASR / ESC) as a major special project for many years in a row. Four-wheel independent drive is listed as a major common key technology for key funding. China's FAW, BYD, BAIC and other enterprises in China, as well as Japan's Toyota, Germany's Volkswagen, and American General Motors, are also intensively preparing technical reserves for key technologies of four-...
