Abstract

The invention provides a hill start assisting system for a load-carrying vehicle and a control method thereof. The system comprises a two-position three-way solenoid valve and a control module connected with the two-position three-way solenoid valve. The two-position three-way solenoid valve is in series connection with a loop between a hand-braking handle and a relay valve. The relay valve is connected with a parking brake. According to the method, hill start assistance is conducted on the vehicle through the hill start assisting system. By the adoption of the system and the method, automatic coordination of clutch engaging and hand braking release through the hill start assisting system is achieved, the phenomenon of slide or flameout of an AMT vehicle during hill start is avoided, and smooth and steady start of the vehicle on a ramp is achieved; safety and simplicity are achieved, and engineering realization is easy; the system and the method can be applied to design of any hill start assisting control system of the load-carrying vehicle carrying an AMT, so that the pavement adaptability of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle slope control, in particular to a slope start assist system for a load-carrying vehicle and a control method thereof. Background technique [0002] With the continuous growth of energy transportation, commodity circulation and population flow, my country's commercial vehicles have developed rapidly in recent years. As a high-tech product that reduces the labor intensity of drivers and improves vehicle safety, automatic transmissions will be The opportunity of the rapid development of automobiles has been more and more applied. Based on the national conditions of a large number of manual transmissions equipped with commercial vehicles in my country, AMT transmissions have become an important direction for the advancement of transmission automation technology in my country and play a pivotal role. [0003] The starting operation process of the AMT gearbox is the same as that of the manual gearbox. W...
