Problems solved by technology

Generally speaking, the existing research tends to study the driving behavior of vehicles on the road section, and there are few studies on the car-following and lane-changing behavior of vehicles at intersections, and most of the existing research focuses on car-following or lane-changing behavior One of the two, few studies have been able to combine the two in one scenario for research

Abstract

The invention discloses an intelligent vehicle intersection right-handed rotation lane gap selection method and device. The method comprises the following steps: acquiring lane change microscopic information of a target vehicle; calculating a lane changing pressure coefficient of the target vehicle; calculating a critical safe lane changing gap allowing the target vehicle to change into the targetlane; calculating an actual lane changing gap in the target lane; judging a lane changing opportunity; the target vehicle decelerates according to the suggested acceleration to wait for the lane changing opportunity meeting the safe lane changing condition; and repeating the steps until the target vehicle meets the safe lane changing condition, and switching to enter the target lane. The method comprehensively considers the influence of the geometrical characteristics of the front and rear vehicles of the lane changing vehicle, the front and rear vehicles in the target lane and the intersection on the lane changing behavior of the vehicle, determines a more accurate lane changing opportunity point, and gives a suggested acceleration, thereby providing a reasonable judgment and decision basis for the right lane changing behavior of the intelligent vehicle at the intersection, and providing a guarantee for safe and efficient operation of vehicles in the intersection.

Description

technical field [0001] The invention relates to the field of intelligent traffic control, in particular to a method and device for selecting a gap in a right transition lane at an intelligent vehicle intersection. Background technique [0002] With the qualitative leap in computer computing power and the amazing launch of 5G technology, with the help of many precise on-board sensors, vehicles can already obtain accurate driving status data during driving, and can realize interconnection with other vehicles to obtain comprehensive and multi-dimensional information. hierarchical data. Therefore, fully, correctly and rationally mining and using these data can greatly improve the traffic capacity of the traffic system and ensure that vehicles can operate in a stable and safe environment. [0003] The driving behavior of the vehicle can be mainly divided into longitudinal car-following behavior and lateral lane-changing behavior. The car-following behavior mainly considers the b...
