Sensor test environment cabin for vehicle in-loop test and test method

Abstract

The invention relates to a sensor test environment cabin for vehicle in-loop test and a test method, and the environment cabin comprises a motion control system which is used for providing road load simulation for a test vehicle; a traffic environment simulation system used for providing a traffic environment required by the test vehicle; anillumination weather simulation system, used for providing different required illumination conditions and rainy and foggy weather; and a data management platform, used for controlling and managing the data of each system. The test environment cabin can provide a large number of simulation test environments, the working condition of the sensor is more real, and the test authenticity is improved. According to the test method matched with the sensor test environment cabin, various environment elements of the test scene are combined to obtain a large number of simulation test environments, the test integrity is ensured, and the test authenticity is improved.

Description

technical field [0001] The invention relates to the technical field of vehicle testing, in particular to a sensor testing environment chamber and a testing method for vehicle-in-the-loop testing. Background technique [0002] With the development of autonomous driving technology, vehicle-in-the-loop testing has become an important link to ensure the safety of autonomous driving vehicles. [0003] Usually, the vehicle-in-the-loop test needs to input map data, sensor data, etc. into the test vehicle through virtual simulation, and then test the performance and safety of the vehicle in a relatively large open field. However, the test scenarios used in the traditional vehicle-in-the-loop test are too single, and it is difficult to simulate the sensor performance of the sensing module under real light and rainy and foggy weather or extreme weather such as strong light, resulting in inaccurate test results and poor integrity of the vehicle-in-the-loop test. [0004] When the test...

However, the test scenarios used in the traditional vehicle-in-the-loop test are too single, and it is difficult to simulate the sensor performance of the sensing module under real light and rainy and foggy weather or extreme weather such as strong light, resulting in inaccurate test results and poor integrity of the vehicle-in-the-loop test

[0004] When the test needs to interact with pedestrians and other vehicles, if the test fails, it is easy to cause harm to the vehicle or personal safety, resulting in lower safety of the traditional vehicle-in-the-loop test
