Embodiment Construction

[0048] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0049] The test method for fault handling of the vehicle controller in the embodiment of the present invention is used to test how the vehicle controller handles these faults after triggering battery and motor-related faults. The test method fully simulates the vehicle controller in different scenarios ( Fault handling under working conditions).

[0050] Such as figure 1 As shown, the testing method of the fault handling of the vehicle controller of the embodiment of the present invention includes:

[0051] Step 101, triggering one or more faults respectively under various preset simulated real vehicle scenarios;

[0052] Step 102, obtaining the first processing data of the vehicle controller for the triggered fault in each simulated real vehicle scena...

Abstract

The invention provides a method and a device for testing the failure processing of a vehicle control unit, relating to the technical field of automobile testing. According to the method and the device, the problem of incomplete testing cover degree of relevant tests of the vehicle control unit in the prior art is solved. The method comprises the following steps: respectively triggering one or more faults in multiple preset simulated real vehicle scenes; acquiring first processing data aiming at a trigger failure of the vehicle control unit in each simulated real vehicle scene; and detecting whether the processing, aiming at the trigger failure, of the vehicle control unit is correct according to the first processing data. According to the scheme, multiple failures can be simultaneously triggered, and the comprehensive testing of multiple simulated real vehicle scenes is realized, so that the testing cover degree is increased, the real vehicle testing risk is reduced, the product quality is guaranteed, and the satisfaction degree of a consumer is increased.

Description

technical field [0001] The invention relates to the technical field of automobile testing, in particular to a testing method and device for fault handling of a vehicle controller. Background technique [0002] At present, when testing related to vehicle controller faults, more attention is paid to the test after a single fault is triggered in a single scenario, and even some faults are not tested. However, when the vehicle is actually running, failures may occur in any scenario, and multiple failures may occur at the same time. Therefore, only a single fault triggering in a single scenario is tested, and the test coverage is not complete, so that the product quality cannot be guaranteed. The resulting vehicle may have security vulnerabilities that endanger the safety of users. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a testing method and device for fault handling of the vehicle controller, so as to solve ...
