Abstract

The invention discloses an unmanned automobile test fault object simulation system in the technical field of unmanned driving test, and the system comprises a steel frame structure which is fixed above a lane; the track is fixed to the top of the steel frame structure, and a load moving assembly is arranged on the track; and the fault object system is located on the lane and connected with the load moving assembly, and the fault object system can be driven by the load moving assembly to move along the track and perform fault object motion simulation in combination with the rotation motion of the fault object system. According to the invention, the load moving assembly is arranged on the steel frame structure, so that the influence on the road surface is less, and various motion forms can be conveniently simulated.

Description

technical field [0001] The invention relates to a fault object simulation system for unmanned vehicle testing, belonging to the technical field of unmanned driving testing. Background technique [0002] Unmanned vehicle testing is a professional field that has emerged along with the development of unmanned vehicles, and it is also an important channel connecting the development and commercialization of unmanned vehicles. With the advancement of unmanned driving technology and the improvement of safety and reliability requirements for unmanned driving, the testing of unmanned vehicles has become an important direction of industry development. [0003] At present, there are two main methods of testing driverless cars, one is the "test field test" in a closed area, and the other is the "road test" on the actual road. Among them, there are various road conditions in the "on-road test", including highways, urban roads, country roads and other road surfaces, which cannot provide ...
