Abstract

The invention discloses a vehicle and a differential lock anti-skid control method and system thereof. The method includes the following steps that the wheel speed of each wheel in the multiple wheelsof the vehicle is acquired; the vehicle speed of the vehicle is calculated according to the wheel speed of each wheel; according to the vehicle speed of the vehicle and the wheel speed of each wheel,the slip rate of each wheel is correspondingly obtained; and according to the slip rate of each wheel, locking or unlocking control is conducted on each differential lock of the vehicle, differentiallock anti-skid control conducted in the high-speed traveling and steering processes can be achieved, and vehicle stability is guaranteed.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a vehicle differential lock anti-slip control method, a vehicle differential lock anti-slip control system and a vehicle. Background technique [0002] Vehicles in the related art generate control signals according to the state of the differential lock switch and the state of the vehicle speed, and drive or prohibit the operation of the differential lock according to the generated control signal, so as to realize automatic control of the differential lock and avoid human factors. Differential lock rattle problem. [0003] But the problem is that the differential lock is kept unlocked when the vehicle is at high speed and turning, and the vehicle may slip, which will affect the stability of the vehicle. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. For this reason, the firs...
