Abstract

The invention relates to a drive-by-wire chassis control method and device, a controller and a storage medium. The method comprises the steps of obtaining at least one piece of fault information related to the drive-by-wire chassis based on working parameters of the drive-by-wire chassis; determining a hazard factor matched with the fault information, wherein the hazard factor is used for representing the occurrence probability and the hazard degree of the hazard event; based on the fault information related to the drive-by-wire chassis and the hazard factors matched with the fault information respectively, safety factors corresponding to the drive-by-wire chassis are obtained through calculation; and determining a target fault level corresponding to the drive-by-wire chassis according to the safety factor, and generating drive-by-wire chassis control information matched with the target fault level, thereby automatically performing level division on the current overall fault, and automatically executing different processing strategies for different fault levels. By adopting the method, the harm caused by the fault can be effectively evaluated, the fault can be accurately handled, and the potential safety hazard can be eliminated.

Description

technical field [0001] The present application relates to the technical field of automatic driving, and in particular, to a control method, system device, controller, storage medium and computer program product of a wire-controlled chassis. Background technique [0002] With the rapid development of automobile intelligence, intelligent driving technology has been widely used in various work scenarios. The safety and reliability of intelligent driving vehicles is a key factor for the commercialization of intelligent driving vehicles. [0003] Intelligent driving vehicles are mainly transported by wire-controlled chassis equipped with intelligent driving system. As a collection of intelligent driving system actuators, wire-controlled chassis can execute the commands of intelligent driving system safely and stably, especially when applied to L4 level. The drive-by-wire chassis of autonomous vehicles above and above needs to have fault monitoring and processing capabilities, so...
