Problems solved by technology

However, for the vehicle early warning function of the OBU, there are many bottlenecks in the actual vehicle outdoor road test:
[0005] First, the overall test cycle is long, requiring more engineers and drivers to participate, and the test cost is high, resulting in low test efficiency;
[0006] Second, C-V2X has many functional scenarios, and many complex scenarios are difficult to achieve, such as high-stress scenarios with hundreds of vehicles;
[0007] Third, certain scene tests have safety threats and are difficult to carry out, such as red light warning, vehicle forward collision warning, blind spot warning, etc.
[0008] Fourth, in the vehicle environment during the test, it is difficult to have a good development and debugging environment, which leads to a long period of time to solve the problem after the test fails.
[0009] Based on the above situation, there are many bottlenecks in the testing of the on-board early warning function of vehicles at present, and it is difficult to simulate various complex road conditions, resulting in fewer scene samples for early warning testing and imperfect early warning testing, resulting in low test accuracy and high cost. Long cycle and low efficiency

Abstract

The invention provides a vehicle-mounted early warning test method and device based on a sand table, a computer and a storage medium. The method comprises the steps : acquiring at first sand table position information and first speed information of a main test vehicle on the sand table; converting the position information of the main test vehicle on the sand table into first positioning information based on satellite positioning; converting the first speed information of the main test vehicle into second speed information based on satellite positioning; acquiring driving information of a remote test vehicle; and according to the first positioning information, the second speed information and the driving information of the remote test vehicle, performing early warning judgment and detection based on an early warning algorithm, and sending an early warning signal to the test terminal. The position and the speed of the main test vehicle on the sand table are mapped into position information and speed information based on satellite positioning, so that the vehicle-mounted unit can make early warning judgment according to the position information and the speed information based on satellite positioning, generates an early warning signal and sends the early warning signal to the test terminal, and the test terminal receives the early warning signal.
