Problems solved by technology

This has led to many problems in the testing of vehicle-road coordination vehicle-mounted unit software
First, in the stage of software integration, there is no mature test tool; the complexity of the PC5 interface interaction data itself makes the construction of test data quite cumbersome and difficult
Second, in the field test stage, the test environment may be highways and complex urban traffic scenarios. In addition, various extreme scenarios, such as collisions, etc. are considered; this brings many limitations and dangers to the field test

Embodiment 1

[0072] According to the system of a kind of vehicle-mounted unit testing software provided by the present invention, comprise:

[0073] Module M1: convert the relevant parameters specified in the C-V2X data interaction standard corresponding to traffic participants into real traffic scene data by referring to the preset proportional relationship through the simulation test program;

[0074] Module M2: Classify and send the converted real traffic scene data to the function library inside the on-board unit OBU in a preset format;

[0075] Module M3: The function library inside the on-board unit OBU converts the converted real traffic scene data into PC5 interface data format according to classification, and pushes it to the V2X application.

[0076] Specifically, the module M1 includes:

[0077] Module M1.1: According to the selected test scenario, set and initialize the relevant parameters specified in the C-V2X data interaction standard corresponding to the traffic participan...

Embodiment 2

[0133] Embodiment 2 is a modification of embodiment 1

[0134] The software framework of the present invention and system are made up of two parts:

[0135] 1) The function library (static library or dynamic library) residing in the on-board unit OBU;

[0136] 2) A simulation test program residing in a test terminal (such as a PC).

[0137] 1. The man-machine interface mainly presents the speed, heading, and position relationship of traffic participants; the man-machine interface can be realized as a host program interface. The test terminal is the operating carrier of the man-machine interface program and the simulation test program (that is, the simulation test data generation program). The function library of the on-board unit device plays the role of the V2X module. While receiving the data generated by the simulation test program, it simulates the V2X module interface and pushes the PC5 interface data to the V2X application program.

[0138] 2. The principle of the man...

Embodiment 3

[0158] Embodiment 3 is a modification of embodiment 1 and / or embodiment 2

[0159] work process:

[0160] 1) The tester selects the test scene through the man-machine interface, and sets the initial position, speed, heading and other parameters of the traffic participants. After that, click Start Test. During the test, the testers fine-tuned the speed, heading and other parameters of the traffic participants.

[0161] 2) The simulation test program periodically updates the relevant parameters of the traffic participants according to the initial setting parameters.

[0162] 3) The simulation test program generates latitude and longitude information according to the screen coordinate conversion, encapsulates other relevant parameters, and generates structured classification data according to the types of traffic participants and equipment types.

[0163] 4) The simulated test program encodes the structured classification data and sends it to the on-board unit OBU.

[0164] 5...

Abstract

The invention provides a system and a method for testing software by a on-board unit. The system comprises a module M1, a module M2 and a module M3, wherein the module M1 is used for converting related parameters specified in a C-V2X data interaction standard corresponding to a traffic participant into real traffic scene data through a simulation test program by referring to a preset proportionalrelation; the module M2 is used for sending the converted real traffic scene data to a function library in the OBU in a classified manner in a preset format; and the module M3 is used for converting the converted real traffic scene data into a PC5 interface data format according to classification by a function library in the OBU and pushing the converted real traffic scene data to a V2X application program. The test of the vehicle-road cooperative application scene is realized through a pure software method, the risk is reduced, the efficiency is improved, and the cost is saved.

Description

technical field [0001] The present invention relates to the field of vehicle-infrastructure collaboration, in particular, to a system and method for testing software of a vehicle-in-vehicle unit, and more specifically, to a software testing device for C-V2X vehicle-infrastructure collaboration, a C-V2X vehicle-infrastructure system for a vehicle-in-vehicle unit. A testing method for collaborative application scenarios. Background technique [0002] GB / T 31024 defines the data interaction standard between vehicle-infrastructure units, roadside units, and vehicle-mounted units in the field of vehicle-road coordination. The connotation of interactive data is very rich. This has led to many problems in the testing of vehicle-road coordination vehicle-mounted unit software. First, there is no mature test tool in the software integration stage; the complexity of the PC5 interface interaction data itself makes the construction of test data quite cumbersome and difficult. Second, ...
