Finished car controller test platform and control method

Abstract

The invention discloses a finished car controller test platform. The finished car controller test platform comprises a platform main controller, a data collection card, a signal excitation board card, a CAN (controller area network) communication board card, a display card and a display device, wherein the platform main controller is used for transmitting an excitation signal which is transmitted to a finished car controller to a finished car controller to be tested via a BOB connecting board through the signal excitation board card and the CAN communication board card, the response and feedback signal of the finished car to be tested is collected by the data collection card and the CAN communication board card and is displayed on the display device by the display card through the BOB connecting board, and the BOB connecting board is connected with the finished car controller to be tested through a plug-in. The invention also provides a control method of the finished car controller test platform. The finished car controller test platform and the control method can be widely used for verifying the control strategy of the finished car controller of different pure electric car types, so that the reliability of the control strategy on a real car can be guaranteed, the test efficiency of the finished car control strategy is improved, the development period of the control strategy is shortened, and the success in developing the finished car controller is guaranteed.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a vehicle controller test platform and a control method using the platform. Background technique [0002] As a key component of a pure electric vehicle, the vehicle controller's control strategy is the core command system of the vehicle's operating mechanism, issuing vehicle driving mode commands, component action commands, monitoring the operating status of each component, and so on. It is not only related to the normal operation of the vehicle, but also to the safety of the vehicle and personnel. Therefore, it is particularly important to test the control strategy of the pure electric vehicle. [0003] At present, the test of the control strategy of the vehicle controller is generally to install the vehicle controller on the real vehicle, and gradually discover the defects and other problems in the design of the vehicle control strategy during the debugging process...

AI Technical Summary

Problems solved by technology

This kind of test is not only time-consuming, but also inefficient. At the same time, the wiring of the real vehicle is intricate and the space is small, resulting in repeated and lengthy processes for finding and solving problems, and even some hidden problems are not easy to be found.

Moreover, it is not easy to organize and analyze the debugging test data in the real vehicle debugging stage, and it is not easy to accumulate development experience, resulting in a long test cycle and low test efficiency for the vehicle control strategy.
