The invention discloses an automatic test device and method for the vehicle control unit of a new energy vehicle. The device is composed of a tested vehicle control unit, a tool vehicle control unit used for realizing vehicle model data interaction and modification and interactively connected with the tested vehicle control unit, a test module used for program burning, test mode switching and datainteraction between the two vehicle control units, a principal computer used for test process detection control and storage, and a motor test bench used for test condition simulation. The method comprises the following steps: the system is initialized, the principal computer sends a control command to start the tested vehicle control unit, and the tested vehicle control unit controls the runningof a motor through a motor controller of the motor test bench; and test items are started, and the principal computer displays and stores the data of the test items. The test efficiency is improved, and the cost is reduced. The automatic test device and method are easy to operate, and have strong adaptability. The development efficiency of the vehicle control technology is improved, and the vehicle control performance and safety are ensured.
Description
technical field [0001] The invention relates to an automatic testing method for a whole vehicle controller of a new energy vehicle. Background technique [0002] As the core component of the new energy vehicle control system, the vehicle controller plays a key role in the safe and reliable operation of the vehicle. The development of related testing technologies can improve the development efficiency of the vehicle controller, simplify the functional testing process, and improve the delivery efficiency. has an important role. Most of the existing test devices use industrial control boards to test the vehicle controller, the implementation method is complex, the test development is difficult, and the efficiency is low; at the same time, the existing test devices are mostly developed for specific functions, and the adaptability needs to be improved. It is necessary to design an automatic testing device and method for a vehicle controller with low cost, simple implementation a...
