Problems solved by technology

For the three-axle passenger car with air suspension system, the manufacturer generally adopts the ECAS (Electronic Control Air Suspension) control system with axle load control to realize it. The system collects the pressure signal on the pressure sensor, controls the suspension airbags of the drive axle and the follower axle to inflate and deflate, thereby adjusting the pressure in the airbags of the two axles, and realizes the axle load transfer between the drive axle and the follower axle. The manufacturer can according to the vehicle According to the requirements of working conditions, through the ECAS control system, the air bag pressure of the driving axle is increased, and then the axle load of the driving axle is increased, and the ultimate driving force of the driving axle is increased. However, the use of the ECAS control system with axle load control will make the The cost of the whole vehicle increases a lot, and at the same time, the circuit connection and gas circuit connection of the ECAS control system with axle load control are relatively complicated, which reduces the production efficiency

Abstract

The invention discloses a tri-axle load distribution control system, and relates to the technical field of automobile control systems. According to the tri-axle load distribution control system, when a limit axle load of a drive axle needs to be enlarged, the pressure of an air bag of an auxiliary axle is decreased to a specified value, the axle load of the auxiliary axle is transferred to the drive axle, the relative pressure in the air bag of the auxiliary axle is controlled, the axle load of the auxiliary load is limited, the problem that a large number of loads of the drive axle are transferred to the auxiliary axle due to a height valve or an ECAS is solved, the service life of the auxiliary axle is prolonged, and tire wear of the auxiliary axle is reduced; the tri-axle load distribution control system has the advantages of being simple in structure, easy and convenient to install, low in production cost and high in production efficiency.

Description

technical field [0001] The invention relates to the technical field of automobile control systems, in particular to an axle load distribution control system for a three-axle passenger car. Background technique [0002] At present, customers who use passenger cars often put forward higher requirements on the driving force and gradeability of the vehicle when the vehicle is fully loaded, but a large gradeability needs to correspond to a large ultimate driving force, and a large extreme driving force requires matching Axle load, and currently there are laws and regulations in many countries that clearly set limit requirements for the axle load of the drive axle of a three-axle bus, which often contradicts the requirement for the vehicle to provide a large driving force. For the three-axle passenger car with air suspension system, the manufacturer generally adopts the ECAS (Electronic Control Air Suspension) control system with axle load control to realize it. The system collec...
