[0004] Adopt the first existing judgment method, although the results obtained are relatively accurate, but human subjective judgment requires a lot of labor costs and does not have scalability
However, with the second existing judgment method, although the calculation cost is relatively small, in more complex scenarios, the vehicle cannot drive to the speed limit due to various reasonable reasons, which will cause the second existing judgment method to appear Situation of miscarriage of justice

The invention discloses a method, a device and equipment for evaluating traffic blocking behaviors of a vehicle and a storage medium. The method comprises the following steps: acquiring a reference speed and a reference speed ratio of a main vehicle at each moment in a scene; integrating the average reference speed ratio and the window duration of the main vehicle in each time window in the scene to obtain the traffic obstruction degree of the main vehicle in each time window; and selecting the traffic obstruction degree of the time window with the lowest traffic obstruction degree as the scene traffic obstruction degree of the main vehicle. According to the invention, whether the vehicle has the bad behavior of obstructing the traffic can be accurately judged, the labor cost can be reduced, and the expandability is high.
Description
technical field [0001] The present invention relates to the technical field of automatic driving, in particular to a method, device, equipment and storage medium for evaluating vehicle obstruction traffic behavior. Background technique [0002] In the practice of autonomous driving technology, judging the performance of autonomous driving vehicles in the simulation environment mainly stays in the dimensions of safety and comfort such as whether the vehicle has collided and whether the vehicle has sudden braking. [0003] As for whether the self-driving vehicle has bad behaviors that hinder traffic, there are currently two main methods for judging. Among them, the first is to directly use manual judgment, and the second is to compare the speed of the vehicle with the speed limit in the process of driving. ratio. [0004] Using the first existing judgment method, although the results obtained are relatively accurate, the subjective judgment requires a lot of labor costs and d...
