Document Type and Number:
WIPO Patent Application WO/2022/242336
Kind Code:
A1
Abstract:
A differential lock control system and method, and a vehicle. The differential lock control system comprises a controller (101), and a front axle differential lock (102), a central differential lock (103) and a rear axle differential lock (104) which are respectively connected to the controller. The controller is used for: acquiring, in response to having received a first locking instruction, a first traveling speed and a front wheel speed difference of a vehicle, wherein the first locking instruction is used for instructing the front axle differential lock to be locked; when both the central differential lock and the rear axle differential lock are locked, determining whether the first traveling speed and the front wheel speed difference meet a first preset locking condition; and when the first traveling speed and the front wheel speed difference meet the first preset locking condition, controlling the front axle differential lock to be locked. By means of the differential lock control system, a control policy for three differential locks is realized, such that the problem of steering limitations caused by using a front axle differential lock alone is avoided, and the risk of failure due to improper use of the front axle differential lock can also be reduced.
