Problems solved by technology
Traditional CAN network testing methods are not fully suitable for CAN network testing of pure electric vehicles
[0006] The existing pure electric control strategy debugging methods have problems such as high cost, dependence on foreign motor battery models, long model configuration time, large gap between model performance and actual performance, and existing network test methods cannot simulate the harsh electromagnetic environment of pure electric vehicles.

Embodiment Construction
[0046] The pure electric vehicle control strategy debugging and network testing method includes the following steps:
[0047] (1) Test the vehicle CAN network communication protocol, including the following sub-steps:
[0048] (1.2) Connect the high-voltage wiring harness and the CAN network wiring harness;
[0049] (1.2) After opening the test software, save the vehicle network data;
[0050] (1.3) Set the CAN bus parameters, then start the bus button to monitor and save the vehicle network data in real time;
[0051] (1.4) After the test, turn off and on the bus, open the vehicle network data file, and obtain the message sending status of each node of the vehicle CAN network, bus load rate, receiving code data length monitoring and message cycle;
[0052] (2) Verify the vehicle control strategy, including the following sub-steps:
[0053] (2.1) Connect the high-voltage wiring harness and the CAN network wiring harness;
[0054] (2.2) After opening the test software, save...

The invention discloses a method for achieving control strategy adjustment and network testing of a blade electric vehicle. The method includes the steps that CAN network communication protocols of the finished vehicle are tested, and control strategies of the finished vehicle are verified. Due to the adoption of the method for achieving control strategy adjustment and network testing of the blade electric vehicle, CAN network data of the finished vehicle can be recorded, all conditions being closer to the real environment of the vehicle and possibly occurring can be simulated, and all kinds of tests of a controller of the finished vehicle can be conveniently and quickly carried out at low cost.
Description
technical field [0001] The invention relates to the technical field of pure electric vehicles, in particular to a method for debugging control strategies and network testing of pure electric vehicles. Background technique [0002] In the development process of pure electric vehicles, in order to shorten the prototype vehicle development cycle and ensure the safety of prototype vehicle debugging, it is essential to conduct control strategy debugging and network testing before actual vehicle assembly. [0003] Because when the development of the control strategy of the pure electric vehicle is completed, the prototype vehicle is generally not yet completed, so the test of the control strategy generally requires the help of the corresponding test system. A complete test system needs to be able to provide various signals required by the vehicle controller, collect various outputs of the vehicle controller, simulate the corresponding status of the vehicle and various systems, and...
