Abstract

The invention provides a method for preventing two-axle tires from being abraded and a whole vehicle control unit and system. The method comprises the steps that a front road condition and a vehicle load are obtained, an air spring arranged at a second axle is controlled to be deflated in advance before a vehicle enters a downhil, the distance between the second-axle tires and a vehicle frame is adjusted so as to adjust the loads of the second-axle tires; after the vehicle goes downhill, the loads of the first-axle tires and the second-axle tires can be kept consistent, and the abrasion of the second-axle tires caused by overweight loads is reduced; a first axle tire pressure and a second axle tire pressure are obtained, air inflation or deflation of an air spring arranged at the second axle is controlled according to the first axle tire pressure and the second axle tire pressure so as to adjust the distance between the second axle and a vehicle frame, so that the second axle tire load is adjusted, and the first axle tire load and the second axle tire load are in a balanced state; the load of the second-axle tires can be flexibly and adaptively adjusted according to vehicle conditions and road conditions, and abnormal rapid abrasion of the second-axle tires is reduced.

Description

technical field [0001] The present application relates to the technical field of automobile chassis adjustment, in particular to a method for preventing tire wear on a second axle, a vehicle control unit and a system. Background technique [0002] Existing vehicles with double front axles often have tire wear on the second axle during use, that is, the tires on the second axle wear faster than the tires on the first axle. Abnormally rapid wear of the tires on the second axle will affect the service life of the tires on the second axle, and users need to replace them frequently Second-axle tires will cause increased user costs and market complaints, and will also cause greater safety hazards to vehicle driving safety. The tire wear on the second axle is accelerated. The fundamental reason is that the suspension attitude of the second axle is relatively fixed and difficult to adjust. Increased tire load or uneven load on the tires on the first and second axles will easily cau...
