Embodiment Construction

[0032] At present, when testing the TCU, it is usually necessary to develop a corresponding test script, and then complete the test by running the test script.

[0033] However, the test script not only has a long development cycle, but also consumes a large amount of work. For some simple functional tests, the time consumed is often longer than that of manual testing. Moreover, the logic language of the test script is complicated, and when there are problems in the script itself, it is difficult to manage and find the problem.

[0034] In view of the above problems, the embodiment of the present invention provides a vehicle hardware-in-the-loop test method. When using the method to test the controlled object, the corresponding test information can be read when receiving the test instruction of the controlled object. Furthermore, the read test information can be identified, that is, the input parameters corresponding to the implementation of the basic driving conditions and th...

Abstract

The invention relates to a vehicle HIL test method, device and system. The method may comprise that when a test control instruction relates to a controlled object is received, corresponding test information of the controlled object is read according to the test control instruction, the test information includes identification information corresponding to a basic driving condition and parameter values corresponding to the basic driving condition, the parameter values include first and second values, the first value represents value information required by an input parameter corresponding to thebasic driving condition, and the second value represents value information of a target parameter under the basic driving condition of the vehicle, and the read test information is identified; and thevehicle is controlled to enforce the basic driving condition according to the parameter values in the test information. Thus, vehicle members can be tested more conveniently.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a vehicle hardware-in-the-loop testing method, device and system. Background technique [0002] In the process of vehicle development, testing the various components of the vehicle is an essential operation. Among them, the hardware-in-the-loop test method has high real-time performance, and is usually used to test the control functions of each controller in the vehicle. [0003] Taking the transmission controller (TCU) as an example, when using the hardware-in-the-loop test method to test the TCU, it is usually possible to use the TCU as a black box, input corresponding data into the TCU according to the test requirements, and obtain the output data of the TCU . According to the obtained output data, analyze whether each function of the TCU is normal. [0004] At present, when using the hardware-in-the-loop test method to test the TCU, it is necessary to develop a cor...
