Vehicle fault processing method and device, vehicle and medium

Abstract

The embodiment of the invention provides a vehicle fault processing method and device, a vehicle and a medium. The method comprises the following steps: determining a sensing direction and sensing redundancy corresponding to the sensing direction for a plurality of preset sensors, wherein the sensing redundancy is the redundancy degree of the sensing information output by the sensors in the same sensing direction; acquiring fault state information of the sensors; generating a risk score level corresponding to the perception direction according to the perception redundancy and the fault state information; and executing a corresponding fault strategy according to the risk scoring level. According to the embodiment of the invention, the sensing direction and the sensing redundancy can be determined according to the sensors of the vehicle, and the driving risk is determined and the corresponding fault strategy is executed according to the fault state information of the sensor, so that whether corresponding fault processing needs to be executed or not is prevented from being judged by an artificial experience method, the problems of omission, no inheritance of logic between vehicle models and the like can be effectively avoided, and the driving safety is improved for vehicle sensing hardware of different vehicle models and different functions.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle fault handling method, device, vehicle and medium. Background technique [0002] Vehicles work in a variety of scenarios, and vehicle designs for different working conditions are also very different. Autonomous driving will continue to improve existing vehicles in various fields. [0003] During the use of the vehicle, it is inevitable that hardware failures will occur. At present, when there is a problem with the vehicle's perception hardware, the main solutions include: 1. Do not do emergency treatment for related failure risks. 2. Design simple emergency mechanisms based only on possible failures. 3. The logic formulation of the processing mechanism depends on the experience of people or relevant development engineers. [0004] None of the above three solutions can meet complex autonomous driving conditions, and may even bring safety hazards to the autonomous ...
