Problems solved by technology

However, the detection function of this detection method is limited. If there is no error in the software logic itself during the detection process, but the data that the software logic relies on is tampered with or the data output by a certain component that it relies on is wrong, if the software logic is still used to detect The software function of the vehicle is prone to false detection of software functions, which will affect the location of the fault point and subsequent maintenance

Abstract

The embodiment of the invention discloses a vehicle software fault detection method and device, equipment and a storage medium. The method comprises the steps of obtaining a detection identifier of ato-be-detected software function; determining a corresponding detection logic according to the detection identifier; detecting the to-be-detected software function based on the detection logic; outputting a current detection result; comparing the current detection result with a predetermined theoretical result of the to-be-detected software function; and determining an actual detection result of the to-be-detected software function according to a comparison result. The problem that false detection can be easily caused due to the fact that the to-be-detected software function needs to be detected according to the data on which the software logic depends or the output data of corresponding hardware in the prior art is solved, and the effect of improving the detection accuracy of the to-be-detected software function is achieved. Meanwhile, hardware participation is not needed, implementation is easy, and vehicle maintenance is further facilitated.

Description

technical field [0001] The embodiments of the present invention relate to vehicle technology, and in particular to a vehicle software fault detection method, device, equipment and storage medium. Background technique [0002] A vehicle is a complex mechanical system consisting of thousands of parts with complex functions. In the stage of vehicle development and use, the software logic is used to detect whether the various software functions of the vehicle are normal. [0003] In the prior art, when detecting vehicle software function faults, the legality check of parameters and the monitoring of the running cycle of software functions are often used to determine whether the software is faulty during operation. However, the detection function of this detection method is limited. If there is no error in the software logic itself during the detection process, but the data that the software logic relies on is tampered with or the data output by a certain component that it relie...
