Abstract

Examples of the present invention disclose an auxiliary driving method, device, equipment and storage medium.This method includes: the diagnostic information of each sensor and actuator of the target vehicle in real time, and the diagnostic information of the software functions of each module; according to the diagnostic information of each sensor and the actuator, and the diagnostic information of each module software function, determine the instanceThe failure of the target vehicle auxiliary driving function; according to the failure of the target vehicle auxiliary driving function, determine the auxiliary driving strategy of the target vehicle, and continue to assist the driving in accordance with the auxiliary driving strategy.The above technical solutions improve the stability and fault tolerance of the auxiliary driving system.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of automobile driving, and in particular, to a method, device, device, and storage medium for assisting driving. Background technique [0002] With the advancement of science and technology, the assembly volume of automotive assisted driving systems has grown rapidly. For a multi-sensor multi-function assisted driving system, each functional module has an independent diagnostic function. When any sensor in the assisted driving system fails, the assisted driving function will be withdrawn immediately to reduce the responsibility of the OEM, which leads to the problem of low stability of the assisted driving system. SUMMARY OF THE INVENTION [0003] Embodiments of the present invention provide an assisted driving method, device, device, and storage medium, so as to improve the stability and fault tolerance of the assisted driving system. [0004] In a first aspect, an embodiment of th...
