Example Embodiment

[0076] Example 1

[0077] like figure 2 As shown, the interface automatic testing method of the vehicle controller provided by the first embodiment of the present invention includes:

[0078] Step 201: Obtain a database container file, and generate a test case and a test output file according to the database container file.

[0079] The invention is based on WinForm, after acquiring the database container file, the CAN message parsing algorithm is used to generate the test case, and the test output file is generated according to the database container file. Before generating the test case, it is necessary to process the database container file to generate the CAN message attribute configuration table. The CAN message attribute configuration table mainly includes the ID, signal length, termination bit, variable precision, and offset of the CAN message. , the maximum and minimum values ​​in the physical sense, the situation of sending and receiving, and the number of messages...

Abstract

The invention provides an interface automatic testing method and device for a vehicle control unit. The method comprises the following steps of acquiring a database container file, and generating a test case and a test output file according to the database container file; acquiring a software interface define file, and establishing a corresponding matching relation between the software interface define file and the database container file; and acquiring a program to be tested associated with an interface to be tested in a project to be tested, building a test platform according to the test case, the test output file and the corresponding matching relation, for reference input information, using the test platform to run the program to be tested, and generating a test result for the program to be tested. The embodiment of the invention is optimized based on a traditional interface test platform, a manual link is optimized into automatic generation, a test environment is automatically built, thereby shortening the test period and ensuring the accuracy of CAN (Controller Area Network) message parsing and packing, and improving the quality of vehicle control unit software.

Description

technical field [0001] The invention relates to the technical field of testing, in particular to an interface automatic testing method and device for a vehicle controller. Background technique [0002] Pure electric vehicles use CAN (Controller Area Network, Controller Area Network) as the main network to transmit data, control the main modules such as battery management system, motor controller and vehicle controller, and the CAN bus transmits data in units of messages , so the correct parsing and packaging of CAN messages is very important. However, in the operation process of thousands of CAN messages, errors cannot be avoided, so it is necessary to configure an interface test platform specially for the vehicle controller software. Traditional interface testing requires multi-step manual modification of the .dbc file (database container file), manual matching of the software interface and the variables involved in the .dbc file, and the need to manually build a test envi...
