Interconnection air suspension interconnection control system and interconnection mode switching control method

Abstract

The invention discloses an interconnection air suspension interconnection control system and an interconnection mode switching control method, which are characterized in that on the basis of formulating vehicle smoothness and handling stability indexes, the driving working condition of a whole vehicle is judged through an information acquisition unit, so that priority control smoothness or handling stability under the working condition is determined; and the selection of the interconnection mode is determined according to the index size of the smoothness or the control stability. After the information is processed by the central control unit, an instruction is sent to an interconnection state adjusting mechanism in the interconnection air suspension, and switching of interconnection modes is achieved. The problem of contradiction between smoothness and control stability in the interconnected air suspension can be effectively solved, and the comprehensive dynamic performance of the whole vehicle is improved.

Description

technical field [0001] The invention relates to the field of interconnected air suspension control, in particular to an interconnected air suspension interconnection control system and an interconnection mode switching control method. Background technique [0002] The air suspension system is one of the important systems for the safe driving of the vehicle, which can effectively alleviate the local impact of the road on the vehicle. As a derivative structure of the air suspension, the interconnected air suspension can further improve the ride comfort and road friendliness of the vehicle. It has multiple interconnection modes as one of its main features. [0003] However, different interconnection modes have different effects on vehicle ride comfort and handling stability. Therefore, how to adjust the corresponding interconnection mode under different working conditions so as to give full play to the interconnection characteristics of the interconnected air suspension is an ...

AI Technical Summary

Problems solved by technology

Although the coordinated control of interconnection, vehicle height and damping has been realized, the control system is too complicated, and the adjustment and switching of interconnection under different working conditions has not been considered.

[0006] Although the control method of the interconnected air suspension has made great progress with the efforts of many scholars, the problem of the adjustment and switching of the interconnected mode has not been fundamentally resolved.
