Abstract

The invention discloses an unmanned vehicle testing system and method, so as to test whether an unmanned vehicle can drive normally in different environments. The unmanned vehicle testing system comprises an unmanned vehicle bench, a simulation testing module and an environment simulation module, wherein a to-be-tested unmanned vehicle is arranged on the unmanned vehicle bench; the environment simulation module is used for generating environment data; the simulation testing module is used for carrying out modeling according to the environment data to obtain a virtual scene, and road surface parameters and image data are transmitted to the unmanned vehicle bench; the unmanned vehicle bench is used for enabling the unmanned vehicle bench to act according to the road surface parameters to simulate the road surface state of the unmanned vehicle during a testing process, and the current speed and attitude data of the to-be-tested unmanned vehicle are acquired. The unmanned vehicle testing system disclosed in the invention is unified with the real world testing environment, the real world is simulated, simulation parameters comprising a weather system, a light system, emergency situationsimulation and road surface parameters are added, and the testing result is more accurate.

Description

Technical field [0001] The invention relates to the field of unmanned vehicle testing, in particular to an unmanned vehicle testing system and method. Background technique [0002] A driverless car is an autonomous vehicle. It not only has the conventional functions of a traditional vehicle, such as acceleration, deceleration, braking, forwarding, turning and reversing, etc., but also environmental awareness, path planning, vehicle control, and intelligence Artificial intelligence such as obstacle avoidance. [0003] Part of the current unmanned vehicle testing is to put the unmanned vehicle in a real site to simulate different environments to test the intelligence of the unmanned vehicle, including obstacle avoidance test, traffic signal test, and some unexpected situations. Such as the sudden rush of pedestrians, irregular driving of other vehicles, test whether the unmanned vehicle can still make accurate judgments and normal driving, but this test is too cumbersome, and it con...
