Abstract
Description
Technical Field

[0002] V2X technology refers to the information exchange of vehicles with the outside world, including vehicle-to-vehicle (V2V), vehicle-to-infrastructure (V2I), vehicle-to-network / cloud (V2N), and vehicle-to-pedestrian (V2P). Through this technology, vehicles can obtain the status information of traffic participants on the road, perceive the surrounding environment, and achieve interconnection of all things. This function can enhance the autonomous driving ability, improve driving safety, and reduce traffic accidents.
[0003] With more and more vehicles equipped with V2X functions, the testing of V2X functions has become increasingly important. Currently, most of the tests for V2X functions are carried out by means of hardware-in-the-loop (HIL) simulation testing. In the actual site, at least two vehicles are used to cooperate with the actual test. Since GPS positioning devices need to be installed on at least two vehicles, there is a problem of high cost of HIL simulation testing. In actual vehicle testing, due to the existence of errors, it is very difficult to repeat the test of the same scenario more than twice. Therefore, there are problems such as low authenticity, low test repeatability in actual vehicle testing, and inability to simulate extreme working conditions. Summary of the Invention

The embodiments of the present application will be described below with reference to the accompanying drawings.
[0041] As Figure 1 shown is a flowchart of a method for V2X simulation testing provided by an embodiment of the present invention. The method includes:
[0042] Step 101, set the test scenario of the V2X simulation test, the case information and relative position information of the simulation test case corresponding to the test scenario, and receive the first absolute GPS information and vehicle information sent by the vehicle to be tested. The first absolute GPS information is the initial absolute position information of the vehicle to be tested, the vehicle information is the vehicle information of the vehicle to be tested, and the relative position information is the relative position information of the simulation test case relative to the vehicle to be tested;
[0043] Step 102, obtain the second absolute GPS information according to the relative position information and the first absolute GPS information. The second absolute GPS information is the absolute position information of the simulation test case;
[0044] Step 103: Send the first absolute GPS information, vehicle information, second absolute GPS information, and use case information to the vehicle to be tested, and cooperate with the vehicle to be tested to conduct V2X simulation testing based on the first absolute GPS information, vehicle information, second absolute GPS information, and use case information.
[0045] In the embodiments of the present invention, V2X can be roughly divided into: V2V (vehicle-to-vehicle) and V2I (vehicle-to-infrastructure) according to different test scenarios. The simulation testing device accepts the operations of the simulation testers, sets the test scenarios for V2X simulation testing, and the use case information of the simulation test cases corresponding to the test scenarios. Specifically: if the test scenario is V2V, the simulation test case is a simulated vehicle, and the use case information is the driving speed, heading angle, vehicle status of the simulated vehicle, and the relative position information of the obstacles perceived by the simulated vehicle; if the test scenario is V2I, the simulation test case is an RSU (road side unit), and the use case information is the test map information and the relative position information of the obstacles perceived by the RSU.
[0046] The vehicle to be tested obtains the GPS information of the vehicle through the local GPS device. This GPS information is absolute position information, that is, the first absolute GPS information, and sends the first absolute GPS information to the simulation testing device. Since the simulation testing device is installed on the vehicle to be tested, the simulation testing device sets the first absolute GPS information as the absolute position information of the simulation testing device, which can save the setting of the GPS device on the simulation testing device. The simulation testing device sets the relative position information between the simulation test case and the vehicle compartment to be tested according to the needs of the simulation testing, and converts the relative position information into the second absolute GPS information based on the first absolute GPS information.
[0047] The simulation testing device sends the first absolute GPS information, vehicle information, second absolute GPS information, and use case information to the OBU of the vehicle to be tested through the OBU (on-board unit) to achieve information synchronization, and cooperates with the vehicle to be tested to conduct V2X simulation testing based on the first absolute GPS information, vehicle information, second absolute GPS information, and use case information.
[0048] In an embodiment of the present invention, a test scenario for V2X simulation testing is set, as well as use case information and relative position information of a simulation test case corresponding to the test scenario. The first absolute GPS information and vehicle information sent by a vehicle to be tested are received. Second absolute GPS information is obtained according to the relative position information and the first absolute GPS information. The first absolute GPS information, vehicle information, second absolute GPS information, and use case information are sent to the vehicle to be tested, and V2X simulation testing is carried out in cooperation with the vehicle to be tested according to the first absolute GPS information, vehicle information, second absolute GPS information, and use case information. This enables V2X simulation testing to be carried out without installing a GPS device for obtaining position information on the simulation testing device. At the same time, the simulation test cases are virtually generated by the simulation testing device, which also facilitates repeated simulation testing.

[0051] Step 202, obtain a second UTM projection coordinate (x virtual , y virtual ) = (x + a, y + b) according to the relative position information (a, b) and the first UTM projection coordinate (x, y);
[0052] Step 203, convert the second UTM projection coordinate into second absolute GPS information (lati , long virtual , long virtual ) according to the formula, where

The first absolute GPS information is the initial absolute position information of the vehicle to be tested, the vehicle information is the vehicle information of the vehicle to be tested, and the relative position information is the relative position information of the simulation test case relative to the vehicle to be tested.

The second absolute GPS information is the absolute position information of the simulation test case.
[0056] A simulation test module 303 is configured to send the first absolute GPS information, vehicle information, second absolute GPS information, and case information to the vehicle to be tested, and cooperate with the vehicle to be tested to perform V2X simulation testing according to the first absolute GPS information, vehicle information, second absolute GPS information, and case information.

The simulation test device accepts the operation of the simulation test personnel, sets the test scenario of V2X simulation testing, and the case information of the simulation test case corresponding to the test scenario. Specifically: if the test scenario is V2V, the simulation test case is a simulation vehicle, and the case information is the driving speed, heading angle, vehicle state of the simulation vehicle, and the relative position information of the obstacles sensed by the simulation vehicle; if the test scenario is V2I, the simulation test case is an RSU (road side unit), and the case information is the test map information, the relative position information of the obstacles sensed by the RSU.
[0058] The vehicle to be tested obtains the GPS information of the vehicle through the local GPS device.

Since the simulation test device is arranged on the vehicle to be tested, the simulation test device sets the first absolute GPS information as the absolute position information of the simulation test device, and the GPS device on the simulation test device can be omitted. The simulation test device sets the relative position information between the simulation test case and the vehicle compartment to be tested according to the needs of the simulation test, and converts the relative position information into the second absolute GPS information according to the first absolute GPS information.
[0059] The simulation test device sends the first absolute GPS information, vehicle information, second absolute GPS information, and use case information to the OBU of the vehicle to be tested through the OBU (On-Board Unit) to achieve information synchronization, and cooperates with the vehicle to be tested for V2X simulation testing according to the first absolute GPS information, vehicle information, second absolute GPS information, and use case information.
[0060] In an embodiment of the present invention, the test scenario of V2X simulation testing and the use case information and relative position information of the simulation test case corresponding to the test scenario are set, and the first absolute GPS information and vehicle information sent by the vehicle to be tested are received. The second absolute GPS information is obtained according to the relative position information and the first absolute GPS information, and the first absolute GPS information, vehicle information, second absolute GPS information, and use case information are sent to the vehicle to be tested, and V2X simulation testing is cooperated with the vehicle to be tested according to the first absolute GPS information, vehicle information, second absolute GPS information, and use case information. This enables the V2X simulation testing to be carried out on the simulation test device without installing a GPS device for obtaining position information.
