Automobile suspension control system on bumpy road surface

Abstract

The invention discloses an automobile suspension control system on a bumpy road surface, relates to the technical field of automobile manufacturing, and solves the technical problem of insufficient automobile comfort caused by insufficient optimization of an intelligent control method in the prior art. A road condition image in the moving direction of an automobile is obtained in advance through a data acquisition module, a suspension adjustment coefficient is calculated in combination with a suspension interpretation model and the speed and weight of the automobile, and the automobile suspension is controlled according to the suspension adjustment coefficient; the hysteresis between data acquisition and suspension control is overcome, and the stability and comfort of an automobile on a bumpy road surface are improved; in the process of obtaining the suspension adjustment parameters, the two suspension analysis models including the linear fitting model and the artificial intelligence model are provided, the linear fitting model is low in data demand and high in operation speed, the artificial intelligence model is high in precision, and it can be guaranteed that good stability and comfort of an automobile can be guaranteed in different environments.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and relates to an automobile suspension control technology for bumpy roads, in particular to an automobile suspension control system for bumpy roads. Background technique [0002] The automobile suspension system refers to all the transmission devices of the frame, body and axle quality inspection. Its function is to ensure firm connection and effective shock absorption, thereby improving the comfort and safety of the driver and passengers; and the semi-active suspension Systems and active suspension systems are widely used in current cars because they can be adjusted in time according to road conditions. [0003] For active suspension systems and semi-active suspension systems, different control methods have been proposed to improve their performance, including traditional control methods such as PID control and linear state feedback, as well as intelligent control methods such as neural ...
