Embodiment 2

[0055] This example gives the specific steps involved in LABCAR operation when using the electric vehicle vehicle controller method in the LABCAR system:

[0056] S1. Configure the environment required for model operation, and add the I / O interface of the model; the environment is generally Solver, Fixed, and Tasking mode;

[0057] S2. Click Add module to add the vehicle controller model. Before that, you need to put the .mdl file and the underlying file in the same folder. When importing the vehicle controller model, it will be imported at the same time. Signar conversion modules appear under the RTPC column, and you can add Convert electrical signals into physical signals;

[0058] S3. Add and configure the hardware board required for the test. The specific operation is: add the board configuration file HWC and configure it, double-click Hardware, click the right button of RTPC and Add Item to add Domain. For example: add the power control board ES1391-PWR, which is used to...

Embodiment 3

[0073] The electric vehicle vehicle controller test system provided in this embodiment can be applied to a system composed of a test host computer interface, a LABCAR system and a vehicle controller, wherein the test host computer interface sends the preset content of the required test to LABCAR system; the LABCAR system receives the preset content of the required test sent by the test host computer interface, and generates the corresponding electrical signal required for the operation of the vehicle controller; the vehicle controller receives the electrical signal sent by the LABCAR system , and generate the corresponding control signal according to the electrical signal; the LABCAR system collects the control signal generated by the vehicle controller, and performs closed-loop control according to the control signal, and at the same time, feeds back the simulation operation result to the test host computer interface in real time .

Abstract

The invention provides an electric automobile vehicle controller test method and system, including: configuring an operation environment required by a model, and adding an I/O interface of the model; adding a vehicle controller model required by test and files corresponding with operation; adding and configuring hardware board cards required by test, and simulating load output signals based on test signal demands through pulling up or pulling down a resistor; configuring a CAN channel based on test demands; connecting I/O ports of software and hardware modules; and downloading compiling to form files required by test and perform test. In test, in dependence on test signal demands, and through pulling up or pulling down a resistor, a load output signal can be simulated, which requires no purchase of a load test card, reduces test cost, obtains a wider adjustable range of resistance values and allows a greater coverage rate of simulatable load output signals. Test contents can be compiled, so that data information of vehicles under specific conditions can be obtained; meanwhile, high voltage does not exist in test, which avoids potential safety hazards to a great extent.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a method and system for testing a vehicle controller of an electric vehicle. Background technique [0002] Electric vehicles refer to vehicles that use vehicle-mounted power supplies as power, drive vehicles with motors, and meet the requirements of various road traffic safety regulations. Because electric vehicles have less impact on the environment than traditional vehicles, they are widely considered to be one of the main ways to solve problems such as vehicle exhaust pollution and oil energy shortages. The power system of an electric vehicle is mainly composed of a power battery, a power battery manager, a drive motor, a starter motor controller, and a vehicle controller. The vehicle controller is the core of the electric vehicle control system, responsible for the control, coordination and monitoring of the overall operating status of the vehicle. Its main functions includ...
