Problems solved by technology
When current self-driving vehicles pass through intersections, there is a problem of insufficient vehicle competition
At present, there are relatively mature evaluation systems for the performance of self-driving vehicles on regular roads, such as car following and lane changing, but there is no recognized and effective method for intersection scenarios.

The invention discloses a method for evaluating the performance of an automatic driving vehicle at an intersection, which includes a test vehicle and at least one background vehicle, and includes: acquiring kinematic parameters and motion state response data of the test vehicle passing through the intersection; Data; calculate the safety index and comfort index according to the quantified kinematic parameters; calculate the intelligence index according to the quantified motion state response data; calculate the performance of the test vehicle according to the weighted calculation of the safety index, comfort index and intelligence index composite index. The invention has the beneficial effects of comprehensively evaluating the safety, comfort and intelligence capability of the automatic driving vehicle when passing through the intersection, and provides an automatic driving vehicle intersection performance evaluation system, including a data acquisition device and a data processing device, which can comprehensively evaluate Safety, comfort, and intelligence capabilities of autonomous vehicles through intersections.
Description
technical field [0001] The invention relates to the technical field of automobile automatic driving. More specifically, the present invention relates to a method and system for evaluating the intersection performance of autonomous driving vehicles. Background technique [0002] With the continuous development of automotive technology, the evaluation of autonomous driving capabilities is a major difficulty facing the industry, especially when current autonomous vehicles need to share the road with human drivers. The traffic scene at the intersection is the most common typical scene in daily driving, and it is also a scene with very high traffic complexity. When current self-driving vehicles pass through intersections, there is a problem of insufficient vehicle competition. At present, there are relatively mature evaluation systems for the performance of self-driving vehicles on regular roads, such as car following and lane changing, but there is no recognized and effective ...
