Embodiment 1

[0025] This embodiment provides a vehicle controller testing device for an electric vehicle, which is used to test the vehicle controller 70 to be tested, such as figure 1 As shown, it includes a main control module 10, a simulation control module 20 and a fault judgment module 30, wherein:

[0026] The inside of the main control module 10 is preset with a control model and a battery management system simulation model; the control model is used to simulate the wake-up signal of the vehicle controller to be tested, and the battery management system simulation model is used to simulate the battery Running state: the main control module 10 can be realized by a computer with a processor chip, and the control model and battery management simulation model can be realized by software. In actual implementation, the same operating environment as that of the battery management system can be built, and the actual software packages and program packages in the battery management system can...

Embodiment 2

[0035] In the electric vehicle controller testing device provided in this embodiment, the main control module 10 is realized by the cooperation of the upper computer 11 and the real-time computer 12, and the two are connected through Ethernet. like figure 2 As shown, the simulation control module 20 is realized by the vehicle control simulation cabinet, and also includes a fault injection sub-module 22, and the fault injection sub-module 22 sends a battery fault simulation signal to the main control module 10; the battery management system The simulation model simulates the operating state of the battery at fault corresponding to the battery fault simulation signal, and feeds back the simulated battery operating state data to the vehicle controller 70 under test. By adding the fault injection sub-module 22, simulating possible faults of the battery during the operation of the electric vehicle can make the test results of the vehicle controller more complete and closer to real...

Abstract

The invention provides a whole car controller test device of an electric car. The device comprises a main control module, a simulation control module and a fault judgment module, wherein a control module and a battery management system simulation model are preset in the main control module, the battery management system simulation model can be matched with a simulation signal transmission board card in the simulation control module, and thus signal transmission between the main control module and a whole car controller to be tested is ensured. The fault judgment module tracks and records signal transmission and feedback results between the main control module and the whole car controller to be tested, the quantity of sensors and the quantity of wiring harnesses are greatly reduced, each interface does not need to be tested artificially, and a test result can be directly reflected via a software model. The test period can be greatly shortened, and the working strength of operating personnel and the operation cost are reduced.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a test device for a controller of an electric vehicle. Background technique [0002] In recent years, with the development of the economy and the improvement of people's living standards, people's consumption needs have begun to upgrade, and the demand for housing, cars, and the environment has become higher and higher. As an emerging travel tool, electric vehicles have It consumes less energy, takes into account both excellent power and a comfortable driving environment, and is widely recognized for its zero emissions to the environment. Therefore, in order to better promote the electric vehicle industry, it is necessary to conduct a large number of tests on the various performance and reliability of the most important vehicle controller in electric vehicles to ensure the safety and durability of the vehicle. [0003] At present, the most common method for vehicle m...
