Road condition pre-identification system for vehicle suspension control based on Internet of Vehicles

Abstract

The invention discloses a road condition pre-identification system for vehicle suspension control based on the Internet of Vehicles. The vehicle-mounted terminal ECU and the short-distance communication module perform two-way communication to determine whether the driving direction information in the other party's vehicle information data string is consistent with the own vehicle. Consistent, among all vehicles traveling in the same direction as the own vehicle, judge whether the other vehicle is in front of or behind the vehicle according to the position information in the other vehicle information data string, generate road condition prediction information, and combine the road condition prediction information The road irregularity information and the curvature radius information of the curved road at the preset distance from the position of the vehicle in the vehicle are sent to the vehicle control module of the vehicle; the present invention can transmit the necessary data such as the road condition information ahead to the vehicle suspension The control part is used to solve the hysteresis problem of real-time suspension control and improve the suspension control performance of the whole vehicle.

Description

technical field [0001] The invention relates to a road condition pre-identification system, in particular to a road condition pre-identification system applied to vehicle suspension control based on Internet of Vehicles. Background technique [0002] The identification of road conditions plays an irreplaceable role in the control of vehicle active and semi-active suspensions. Today's working condition identification has two types: real-time working condition identification and working condition pre-identification. Among them, the real-time working condition identification is an identification method in which the vehicle-mounted sensor collects data and the vehicle-mounted processor performs real-time calculation on the collected data to obtain the working condition identification result. Real-time working condition identification has a high dependence on sensor accuracy and processor performance, and at the same time, the lag problem of real-time identification cannot be av...

AI Technical Summary

Problems solved by technology

[0004] In view of the above-mentioned existing real-time operating condition discrimination system’s high dependence on sensors and processors and the problem of lag, and the above-mentioned existing hybrid bus driving condition prediction method based on the Internet of Vehicles has limitations and the above-mentioned existing Internet of Things-based The problem that the pre-identification method of the working condition of the vehicle is expensive and difficult to establish, the present invention proposes a road condition pre-identification system suitable for vehicle suspension control based on the Internet of Vehicles, which is simpler and easier to arrange and implement, that is, to solve the problem of It solves the hysteresis problem of real-time working condition identification and enables information sharing
