Embodiment 1

[0041] In this embodiment, a method for generating a vehicle controller environment model is provided, such as figure 1 As shown, including the following process:

[0042] (1) According to the controlled object of the whole vehicle, configure the controlled object model. The controlled object model here is a physical model, and the controlled object includes one or more of motors, batteries, transmitters, clutches, gearboxes, accessories, complete vehicles, and road conditions. Road conditions are related to automatic testing It is used in conjunction with the test case. If you choose to manually set the test case during the test, you do not need to add the road condition model.

[0043] (2) Configure the virtual controller and select the input and output signals. The virtual controller includes one or more of the engine management system (EMS), transmission controller (TCU), motor controller (MCU), and battery management system (BMS). The pure electric vehicle may not add ...

Embodiment 2

[0049] This embodiment provides a method for generating the environment model of the vehicle controller. The in-the-loop frame diagram of the environment model is as follows figure 2 shown.

[0050]The environment model generating method in the present embodiment is used in the case that the vehicle environment model needs to be established in the model-in-the-loop test, by writing a script function in matlab with M language, and adding and calling the module in the simulink library to automatically generate the environment by command The model is then applied to the model-in-the-loop test. Using the method in this example to figure 2 The environment model part in the software is automatically generated, and the tester selects the module to be generated through the GUI interface and configures the corresponding parameters.

[0051] The automatic generation method of environment model includes the following steps:

[0052] 1) Controlled object model configuration. The con...

Embodiment 3

[0074] In this embodiment, a vehicle controller environment model generation system is provided, such as Figure 4 shown, including

[0075] Controlled object configuration unit: configure the controlled object model according to the vehicle controlled object;

[0076] Virtual controller configuration unit: configure the virtual controller and select input and output signals;

Abstract

The invention provides a whole vehicle controller environmental model generation method. The method comprises steps: according to a whole vehicle controlled object, a controlled object model is configured; a virtual controller is configured, and input and output signals are selected; a test use case is set, and a driver operation signal is simulated; signals received and sent by the whole vehicle controller are processed; and a generation address is selected, and the environmental model is generated. According to the method of the invention, the whole vehicle environmental model can be generated automatically, a model building process is greatly simplified, model building difficulties are reduced, model accuracy is improved, a tester can be freed from high-load work of simulation environment model building, the tester can really focus on the model simulation test work, and the whole test cycle is shortened.

Description

technical field [0001] The invention relates to the field of vehicle controller testing, in particular to a method and system for generating a vehicle controller environment model. Background technique [0002] As the international community pays more and more attention to energy security and environmental protection issues, countries have increasingly stringent requirements on vehicle emissions. Reducing dependence on energy and realizing energy conservation and emission reduction has become an urgent problem to be solved for the sustainable development of the world economy. Hybrid vehicles and pure electric vehicles have become the development trend of today's automobile industry. Gasoline-electric hybrid vehicles combine the motor and the engine to achieve reasonable energy-saving and emission-reduction effects for various working conditions. Hybrid functions such as idling stop, motor starting, intelligent charging, regenerative braking, motor assist, and electric crawl...
