Vehicle driving assistance method and system during yellow light at intersection, electronic equipment and storage medium

Abstract

The invention discloses an intersection yellow light period vehicle driving assistance method and system, electronic equipment and a storage medium, and belongs to the technical field of intelligent driving. According to the method, the yellow light dilemma of a vehicle at a signal control intersection is taken as a starting point, a current decision-making area model of the vehicle is configured according to the current driving position of the vehicle at an entrance lane of the intersection, and the decision-making area model comprises a plurality of groups of decision-making areas; acquiring boundaries of the multiple groups of decision areas, and judging the position of a certain decision area where a vehicle is located when the yellow light at the intersection is turned on; determining a driving strategy according to the position of the certain decision area where the vehicle is located and the current driving information of the vehicle, and outputting the driving strategy to a vehicle-mounted control terminal and / or a driver; by considering the dynamic variability of the yellow light dilemma and the actual decision possibly made by the driver close to the intersection, auxiliary information is provided for the driver during the yellow light period, and the driver is helped to decide whether to pass through the intersection or not.

Description

technical field [0001] The invention belongs to the technical field of intelligent driving, and in particular relates to a vehicle driving assistance method, system, electronic equipment and storage medium during a yellow light at an intersection. Background technique [0002] Intersections are the main areas where traffic conflicts occur in urban roads. The conflicts between traffic flows not only lead to the decrease of road network traffic efficiency, but also make intersections become urban traffic bottlenecks, and also cause intersections to become accident-prone places. According to statistics, the number of accidents occurring near the intersection accounts for about 18% of the total number of accidents, and the traffic accidents that occur during the yellow light time account for more than 50% of the traffic accidents at the entire signalized intersection. Although the total number of traffic accidents in my country has shown a downward trend over the years, the numb...

Problems solved by technology

[0005] In order to solve or at least partly solve the current problem that the vehicle is caught in the yellow light dilemma when the yellow light signal is turned on, causing potential accident risks, the present invention provides a vehicle driving assistance method during the yellow light at the intersection. The yellow light dilemma is the starting point. According to the current driving position of the vehicle at the intersection entrance, configure the decision area model where the vehicle is currently located. The decision area model includes multiple groups of decision areas; obtain the boundaries of the multiple groups of decision areas, and judge when the When the yellow light at the intersection is on, the vehicle is in a certain decision-making area; by considering the dynamic change of the yellow light dilemma and the decision-making options near the intersection, the driver is provided with auxiliary information during the yellow light to help the driver decide whether to pass intersection
