Distributed type horizontal interconnection air suspension control system and method

Abstract

The invention discloses a distributed type horizontal interconnection air suspension control system and method, a sprung mass sensor mechanism, a front axle sprung mass sensor mechanism and a rear axle sprung mass sensor mechanism collect corresponding information and send the information to a corresponding first single chip microcomputer, second single chip microcomputer and third single chip microcomputer respectively, and after the information is processed by the single chip microcomputers, a sprung mass roll angle theta, a front axle unsprung mass roll angle theta <t1> and a rear axle unsprung mass roll angle theta <t2> are obtained respectively and transmitted to a CAN bus through corresponding CAN bus modules; a control mechanism obtains the three roll angles, the result value of theta (theta-theta <t1>) and theta (theta-theta <t2>) are calculated, the result values are compared with 0, and front and rear axle interconnection state closing signals are generated; an execution mechanism obtains interconnection state control signals from the CAN bus and executes the signals; according to the distributed type horizontal interconnection air suspension control system and method, each mechanism is connected with respective single chip microcomputer and CAN bus module, the mechanisms are connected by the CAN bus, the installation positions are free and various, and excellent information shareability and extensibility are provided.

Description

Technical field [0001] The invention relates to an air suspension installed on a vehicle, in particular to a control system of a transversely interconnected air suspension. Background technique [0002] The horizontal interconnected air suspension connects the air springs on both sides of the coaxial line through a pneumatic pipeline, and the connection and closing of the pneumatic pipeline is controlled by the opening and closing of the interconnected solenoid valve. When the interconnection solenoid valve is opened, the interconnection state is turned on. When the road is impacted by unevenness, the exchange of gas in the interconnected air spring can alleviate the impact of the road and reduce the torque carried by the body. When the interconnection solenoid valve is closed, the interconnection state is closed. When the vehicle is turning at a high speed, the influence of the interconnection gas circuit on the body posture can be eliminated, and the operation stability of the ...
