Abstract

The invention relates to a site-in-the-loop test system and test method oriented to the vehicle-road cooperation technology, and belongs to the technical field of vehicle-road cooperation test. The system comprises a perception fusion layer, a data transmission layer and an application layer, and point cloud data are recorded and played back to form a virtual test environment; and according to the method, the tested vehicle can interact with the virtual vehicle in the virtual test environment in the site, various extreme scenes are repeatedly drilled, so that the test method with consistency and repeatability is constructed, a convenient, efficient and low-cost test scheme is provided for the V2X to-be-tested vehicle/equipment, and the test result is closer to the performance in the real environment.

Description

technical field [0001] The invention belongs to the technical field of vehicle-road coordination, and in particular relates to a site-in-the-loop testing system and a testing method for vehicle-road coordination technology. Background technique [0002] Vehicle-road coordination technology is a technology that uses vehicle-mounted and roadside nodes to form a proprietary network to collect and transmit relevant information such as vehicle attitude and road conditions to enhance the perception of the automatic driving system. It has become one of the key technologies for fully automatic driving. one. [0003] Vehicle-infrastructure collaboration technology emphasizes the synergy between the vehicle and the outside world; at present, the test equipment and testing methods of vehicle-road collaboration technology still remain on single-node performance and functional testing. During testing, laboratory tests and simple site-to-point functional tests are usually the mainstays. ...
