Title:
VEHICLE AND COUPLING LOCK CONTROL METHOD AND SYSTEM FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2018/214715
Kind Code:
A1
Abstract:
Provided is a coupling lock control system for a vehicle. The vehicle has a plurality of wheels, the plurality of wheels are configured as at least one set of wheel pairs, and each set of wheel pairs comprises a first wheel (11a) and a second wheel (11b) connected to the same coupling lock (10). After a locking instruction for the coupling lock (10) is obtained, the wheel speeds of the first wheel (11a) and the second wheel (11b) connected to the same coupling lock (10) are obtained. Based on the difference between the wheel speeds of the first wheel (11a) and the second wheel (11b), the difference between the wheel speeds of the two wheels is obtained; based on the ratio of the greater value to the lower value of the wheel speeds of the first wheel (11a) and the second wheel (11b), the ratio of the wheel speeds of the two wheels is obtained; and the locking control of the coupling lock (10) is performed based on the difference between and the ratio of the wheel speeds of the two wheels, thereby enabling the coupling lock to lock quickly and safely, and preventing gear collisions and excessive wear. Further provided is a coupling lock control method for a vehicle.
