AI Technical Summary

Technical Problem

The height adjustment of existing commercial vehicle air suspension relies on manual operation and cannot adapt to road conditions in real time, resulting in insufficient driving stability and fuel economy.

Method used

By acquiring road point data in real time, conducting validity checks and identifying road condition types, building multi-dimensional correlation charts, and dynamically adjusting the suspension height to suit different road conditions, automatic suspension adjustment is achieved.

Benefits of technology

It improves the vehicle's driving safety and comfort, reduces power loss, adapts to complex road conditions, and improves overall performance.

Abstract

The invention discloses a dynamic adjusting method, device and equipment for a vehicle air suspension and a medium. Comprising the following steps: acquiring road point data in real time, including position coordinates, slope values and curvature values; the road points corresponding to the verified effective slope values are first-class look-ahead points, the road points corresponding to the verified effective curvature values are second-class look-ahead points, and road condition type recognition is conducted on all kinds of look-ahead points; searching an end point of the road section in the multi-dimensional association chart by taking the target effective look-ahead point as a starting point; and based on the road condition information of the starting point and the ending point, executing a suspension dynamic adjustment strategy corresponding to the road condition type according to a predefined control rule. According to the embodiment of the invention, a set of data acquisition-processing-decision-execution full-process intelligent suspension adjusting system is constructed, the precise adjustment gets rid of the limitation of manual adjustment, the safety and comfort of vehicle driving are remarkably improved, and the problems that the manual adjustment of the suspension lags behind and cannot dynamically adapt to road conditions in a traditional commercial vehicle scene are solved.
