Test method and test device for vehicle active safety early warning system

Abstract

The invention relates to a test method for a vehicle active safety early warning system. The test method comprises the steps of collecting and storing data; collecting the panoramic video information and the vehicle state information during the actual driving process of a vehicle; adding the panoramic video information and the vehicle state information into the synchronous time information to form a test scene; storing the test scene in a storage device; reproducing the test scene; inputting the test scene in the storage device into a to-be-tested vehicle active safety early warning system at a test site; conducting the function test: namely testing the logic function of the to-be-tested vehicle active safety early warning system. According to the technical scheme of the invention, the test method and the test device for the vehicle active safety early warning system are high in test precision, strong in reliability and low in test cost. The consistency of the real vehicle road test and the off-line test is guaranteed. Meanwhile, the fault reason of a product can be effectively analyzed.

Description

technical field [0001] The invention relates to the field of testing of vehicle-mounted products, in particular to a testing method and testing device for an active safety warning system of a vehicle. Background technique [0002] With the development of global urbanization and the popularization of automobiles, traffic safety issues have attracted more and more attention and attention. Among them, due to subjective factors such as the driver's inability to fully observe the surrounding conditions of the vehicle, fatigue driving, or distraction of the driver, traffic accidents of lane departure are likely to be caused. With the rapid development of automotive electronics, automotive active safety warning integrated products that integrate the functions of Surround View System (SVS: Surround View System) and Lane Departure Warning (LDW: Lane Departure Warning) are more and more valued by automobile manufacturers. Automobile active safety refers to avoiding or reducing accide...

AI Technical Summary

Problems solved by technology

If the test site or road is used to verify the function / performance of the real vehicle active safety warning system, it will take a lot of manpower and material resources, and there are many disadvantages: it is necessary to purchase or rent a test vehicle, and the test cost is high; the real vehicle test work The strength is high, and the instrument panel or central control panel of the vehicle needs to be disassembled. road test; long-term repeated road tests on real vehicles can easily lead to fatigue of testers, misuse and misjudgment, and affect the reliability of the test; To reproduce the state of a specific test scenario, the consistency of the test results is very poor; different and changing test scenarios also bring difficulties and challenges to the testing process
