Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a method for interconnecting a new energy vehicle electric control training platform with an actual vehicle. Background technique [0002] The new energy vehicle electronic control training platform is a platform used in the development of new energy vehicles for controller software development and control strategy teaching. In different scenarios, due to the different controlled objects, the training platform will be derived into various types, such as vehicle controller (VCU) electronic control training platform, battery management system (BMS) electronic control training platform, motor control Controller system (MCU) electronic control training platform, body controller system (BCM) electronic control training platform, etc. [0003] The electric control training platform generally consists of the following parts: system controller, signal simulation unit, sensor...

AI Technical Summary

Problems solved by technology

After the training platform is designed, it can only be used in a single scenario, and the cost is relatively high

[0009] 3. The above two types of training platforms are generally only used to simulate a subsystem

Accurate simulation signals require high-precision models, and high-precision models inevitably require a lot of calculations and actual vehicle calibration work. Limited by the computing power of computers and the level of calibration personnel, the dynamic response and accuracy of boundary signals are actually very low. Difficult to guarantee or high cost

[0011] 5. It is difficult to directly apply the control algorithm developed based on the training platform environment to the real vehicle for inspection

In order to apply to the real vehicle, it needs to spend a lot of energy on the verification and debugging of the interface

[0012] The above problems are rooted in the separation between the controller operating environment generated by the training platform and the real vehicle environment.
