Vehicle stability control method and device, equipment and storage medium

Abstract

The invention discloses a vehicle stability control method and device, equipment and a storage medium. The vehicle stability control method comprises the steps of determining vehicle stability demandparameters in a target time period based on a vehicle driving state in the target time period; determining road stability boundary parameters in the target time period based on a current road state; determining a vehicle stable state in the target time period based on the vehicle stability demand parameters and the road stability boundary parameters; and controlling the vehicle driving state basedon the vehicle stable state. According to the embodiment, the vehicle stable state in the target time period is judged by comparing the road stability boundary parameters with the vehicle stability demand parameters, and the vehicle driving state is adjusted and controlled according to the vehicle stable state. The problem of dangerous consequences such as insufficient control or excessive correction possibly caused by passive control of a traditional vehicle stability control scheme is solved, the vehicle is prevented from being in an unstable state, and it is ensured that the vehicle is always in a safe driving state.

Description

technical field [0001] Embodiments of the present invention relate to vehicle control technology, and in particular to a vehicle stability control method, device, equipment and storage medium. Background technique [0002] With the development of intelligent technology and electronic control technology, people have higher and higher requirements for vehicle driving safety, and the traditional passive stability control system can no longer meet people's needs. [0003] Most of the traditional vehicle stability control schemes are passive control schemes. Only after the vehicle has already experienced an unstable state, for example: the stability requirement exceeds the boundary, causing the vehicle to drift or skid or roll over, can the vehicle be remedied type control. In addition, traditional vehicle stability control schemes only control vehicle instability based on yaw rate or center of mass sideslip angle deviation information. [0004] The scheme of controlling the ve...

AI Technical Summary

Problems solved by technology

In addition, traditional vehicle stability control schemes only control vehicle instability based on yaw rate or center-of-mass sideslip angle deviation information

[0004] The scheme of controlling the vehicle after the vehicle has already appeared in an unstable state may cause dangerous consequences such as insufficient control or overcorrection

According to the yaw rate or the center of mass side slip angle deviation information to control the vehicle instability state, it is easy to cause the vehicle to deviate from the existing driving road

Therefore, the traditional vehicle stability control scheme cannot effectively control the instability state of the vehicle.
