Problems solved by technology

[0005] The above-mentioned first method does not consider the characteristics of the main vehicle and the obstacle target, and adopts a unified division standard for different situations, so the division result is not accurate
The above-mentioned second method relies on the detection of the speed and position of the obstacle target. Since it is difficult to avoid detection errors, the determined results are also inaccurate

Abstract

The invention discloses a method and device for determining a vehicle safe area, electronic equipment and a storage media and relates to the field of intelligent traffic. The method comprises the following specific realization steps: determining the type of an obstacle target within a preset range around a vehicle; searching correspondence relation between type and speed according to the type of the obstacle target, and determining the speed of the obstacle target; and dividing a safe area of the vehicle according to the speed of the obstacle target. The method can improve accuracy of divisionof the vehicle safe area. The scheme can be used in the field of autonomous driving, especially autonomous parking.

Description

technical field [0001] The present application relates to a data field, in particular to an intelligent transportation field. Background technique [0002] At present, two methods are generally adopted for the division of vehicle safety areas. [0003] The first is subjective division. This method divides the forward distance according to the subjective impression, such as 0-3m, 3-6m, 6-12m, etc. [0004] The second is to calculate the safety distance in front of the main vehicle based on the detection of the speed and position of obstacles (such as vehicles, people, objects, etc.). For example, the time to collision (TTC, Time to Collision) distance is calculated to determine the forward safe distance of the main vehicle. [0005] The above-mentioned first method does not consider the characteristics of the main vehicle and the obstacle target, and adopts a unified division standard for different situations, so the division result is not accurate. The above-mentioned se...
