Problems solved by technology

However, the high-precision map can only reflect the direction, width and type of the road, but not the undulations of the road. Therefore, the control parameters cannot be accurately determined based on the high-precision map; The coverage and update frequency cannot meet the availability and accuracy of the information required for suspension control

Abstract

The embodiment of the invention discloses a suspension control parameter adjusting method and device, electronic equipment and a storage medium. The method comprises the following steps: acquiring a current wheel position of a target wheel of a target vehicle and a pre-stored historical driving record; wherein the historical driving record comprises recorded fluctuating information of recorded fluctuating roads passed by the target vehicle in historical driving; determining whether the current wheel position is in a recorded fluctuating road or a near area of the recorded fluctuating road; and if yes, predicting a next driving position of the target wheel, determining next position fluctuation data of the next driving position based on the recorded fluctuation information, and adjusting suspension control parameters based on the next position fluctuation data. According to the technical scheme, the accuracy of the obtained suspension control data can be improved, the suspension is effectively controlled, and the vehicle can run more stably.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle control, and in particular, to a method, device, electronic device, and storage medium for adjusting suspension control parameters. Background technique [0002] One of the purposes of suspension control is to reduce the impact of road undulations on vehicle body vibration, especially for semi-active suspension or active suspension, the characteristics of road undulations determine the selection of control parameters. [0003] In the prior art, a high-precision map is generally adopted, the road conditions are simply understood through the high-precision map, and a control reference is determined according to the road conditions. However, the high-precision map can only reflect the direction, width and type of the road, but cannot reflect the fluctuation of the road, so the control parameters cannot be accurately determined based on the high-precision map; The coverage and f...
