Description

Technical Field

[0001] The present application relates to the field of automobile testing, and in particular to a vehicle local event testing method, device, equipment, medium and automobile. Background Art

[0002] Vehicle local events refer to functions of the vehicle's internal control system or internal network used to monitor or respond to specific conditions or operations. They usually do not need to obtain data from external devices or servers and take action. Their triggering usually only involves the collaborative work between multiple controllers and the vehicle's segmented wake-up strategy, so that the vehicle's internal functions can be quickly processed and managed. With the in-depth development of vehicle electrification, the types and demands of vehicle local events continue to increase. The interactions between their complex types and related functions have problems such as interaction logic errors, controller failure or abnormal response, and poor hardware stability of parts causing vehicle power supply. Therefore, how to effectively and reasonably test the vehicle's local events and ensure that local events are reliably triggered under various conditions is a top priority for ensuring vehicle stability.

[0003] The existing vehicle local event testing method can only be carried out manually, that is, the tester manually triggers different types of local events one by one. This testing process is not only inefficient, but also prone to missed tests and wrong tests due to the defects of manual testing itself. At the same time, some local events need to be tested in combination with the special mechanism of the controller, and manual testing is more difficult at this time. For example, the process of the local event of automatic battery insulation is: the vehicle T-Box is woken up regularly after the whole vehicle sleeps for a hour, and the sub-segment wake-up mechanism is triggered when the battery pack temperature is judged to be lower than the threshold, and only a certain bus is pulled up and the battery pack insulation function is started through the controller. The manual test of this local event requires the tester to wait for a hour and create a low temperature environment to reduce the battery pack temperature. After the function is triggered, it is also necessary to manually judge whether the sub-segment wake-up mechanism is triggered normally, and manually judge the dormancy of the whole vehicle after the battery pack completes the insulation. The testing process is very labor-intensive, material-intensive and time-consuming. Therefore, how to carry out automated testing of vehicle local events is still a problem that needs to be solved in the existing technology. Summary of the invention
