Abstract

The invention provides a vehicle collision analysis method and device, and the method comprises the steps: carrying out the analysis of the driving tracks of a current vehicle and an environment vehicle, and obtaining a possible collision range; and judging whether the new driving tracks of the two vehicles are overlapped with the collision range or not in the driving process of the current vehicle so as to determine whether the two vehicles have the collision risk or not. Thus, the analysis result of the collision risk can provide a basis for adjusting the driving decision under the conditionthat the current vehicle may collide with the environmental vehicle, and the safety of the automatic driving process of the vehicle is improved.

Description

technical field [0001] The present application belongs to the technical field of automatic driving, and in particular relates to a vehicle collision analysis method and device. Background technique [0002] In related technologies, it is usually analyzed whether the trajectories of the self-driving vehicle and other vehicles in the environment intersect at each moment, or whether the body coverage area overlaps, and judge whether there is a risk of collision between the self-driving vehicle and other vehicles in the environment, which cannot be determined. The range where there is a risk of collision cannot provide a basis for timely adjustment and decision-making of self-driving vehicles. Contents of the invention [0003] In view of this, the purpose of this application is to provide a vehicle collision analysis method and device to solve the technical problem that related technologies cannot determine the range of possible collision risks. The disclosed technical soluti...
