METHOD AND APPARATUS FOR DETERMINING LOCKING FORCE OF LIMITED-SLIP DIFFERENTIAL, AND READABLE STORAGE MEDIUM

WIPO Patent Application WO/2024/011970

A1

Provided in the present application are a method and apparatus for determining a locking force of a limited-slip differential, and a readable storage medium. The method comprises: after a target vehicle is started, and on the basis of a preset adhesion coefficient, determining a pre-pressing force, which is pre-applied to a clutch plate corresponding to a target limited-slip differential by the target limited-slip differential when the target vehicle has not skidded; measuring, in real time, the wheel speed difference between a left wheel and a right wheel, which are controlled by the target limited-slip differential; when the target vehicle skids, and on the basis of the wheel speed difference, determining a feedback pressing force by using a feedback control means; and determining the sum of the pre-pressing force and the feedback pressing force to be a locking force of the target limited-slip differential. In the method and apparatus, a pre-pressing force is pre-applied when a target vehicle has not skidded, such that even when a certain driving force is applied, a low-adhesion-side wheel of the target vehicle does not skid.
