Title:
LOCKER DIFFERENTIAL CONTROL METHOD AND SYSTEM FOR ALL-TERRAIN VEHICLE, MEDIUM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2022/135099
Kind Code:
A1
Abstract:
The present application relates to the technical field of vehicle control, and provides a locker differential control method and system for an all-terrain vehicle, a medium, and a vehicle. The method comprises: receiving a terrain mode request signal from an ESP, wherein the terrain mode request signal is used for indicating a terrain mode currently selected by a vehicle; and according to pre-configured matching relationships between different terrain modes and different locker differential states, controlling each locker differential of the vehicle to operate in a locker differential state matching the currently selected terrain mode, wherein the locker differential state comprises a locked state and an unlocking vehicle speed limit-free state of the locker differential. According to the present application, the interaction between the all-terrain mode and the electric control locker differential system is established, so that the electric control locker differential system corresponds to different locking strategies and unlocking vehicle speed limits according to the all-terrain mode to adapt to different road condition requirements, so that the electric control locker differential performance in an off-road mode can be fully exerted.
