Adaptive cruise assisted driving system test field and scene planning method

Abstract

The invention discloses an adaptive cruise assisted driving system test field and a scene planning method. The test field is divided into a central area and surrounding roads; a middle city road runsdirectly through the test field to divide the central area of the test field into an upper part and a lower part; the middle city road is intersected with a cross road to divide the central area of the test field into four parts; a green area is located on the upper left; an open test area is located on the upper right; a lake area is located on the lower right; a the building area is located on the lower left; an avenue area is arranged on one side of a main road of the building area; a roundabout is arranged at the entrance of the main road; a multi-directional/one-way traffic light is arranged at the intersection of the main road; a tunnel in the middle of the city road on the lower right; and a one-way traffic light is arranged on the city road at the lower part. The test field can carry out ACC system test in a compact field, and the test efficiency is high; the scene planning is highly targeted and the considered content is comprehensive; the planned scene covers the current ACCmainstream technology, and has high practicability.

Description

technical field [0001] The technology relates to the field of automobile auxiliary driving systems, especially the planning and design of the test scene of the adaptive cruise system. Background technique [0002] At present, the research on related technologies of intelligent networked vehicles is the strategic development focus of various countries. There are two main development ideas in this field. One is represented by Internet companies such as Google and Baidu. They are taking the road of direct research and development of unmanned driving technology; It is the road of assisted driving. At present, according to the SAE classification method, assisted driving is basically divided into six levels of L0-L5, which are the assisted driving stage (DA), the partial automatic driving stage (PA), the conditional automatic driving stage (CA), and the highly automatic driving stage (HA). ), fully automatic driving stage (FA) 5 levels. At present, the assisted driving system m...

AI Technical Summary

Problems solved by technology

At present, some work has been carried out on the technical test of the system in China, but it is only limited to some roads with simple working conditions (and currently there are few cities open to road tests), and there is no special scene planning, which is not targeted enough; in addition There are a few closed comprehensive testing grounds in China, which mainly serve for the testing of unmanned driving technology, and the testing tasks are heavy and the testing schedule is tight.
