Intelligent driving vehicle active lane changing system considering intelligent traffic flow

Abstract

The invention relates to an intelligent driving vehicle active lane changing system considering intelligent traffic flow. The system comprises a camera, a radar, a wheel speed sensor, an IMU assembly,a communication module, a GNSS module, an ECU module, an HMI module and a motion execution module. A lane changing comprehensive decision-making method comprises the steps: acquiring motion information of a host vehicle and the environmental vehicle, acquiring road basic information, judging the motion gain of lane changing, calculating the corresponding longitudinal minimum safety distance, judging whether the lane changing behavior greatly influences the traffic flow or not, and the like. According to the invention, on the basis of a traditional minimum safety distance model, under the conditions of different roads such as a straight road and a bent road, the influence of the road curvature on the minimum safety distance model is considered, the influence of the lane changing behavior on the traffic flow of the target lane is comprehensively considered, the lane changing system and a comprehensive decision model are established, a feasible decision basis is provided for lane changing of the intelligent networked automobile, and finally a comprehensive lane changing control method which is more comprehensive, more economical and more efficient is obtained.

Description

technical field [0001] The invention relates to an active lane-changing system for intelligent driving vehicles considering the flow of intelligent vehicle groups, in particular to an active lane-changing decision-making system and a comprehensive lane-changing decision-making method for intelligent vehicle groups. Background technique [0002] With the rapid development of information and communication technologies such as cloud computing, big data, and the Internet of Things, we have now entered the era of the Internet where everything is connected. development changes. As one of the traditional manufacturing industries, the automobile industry is also constantly transforming and upgrading in the direction of "smart manufacturing" and "Internet +".

Problems solved by technology

[0004] Lane changing is a driving behavior that often occurs in traffic. When the traffic flow is small, reasonable lane changing behavior will help the vehicle to obtain a higher driving speed; and when the traffic flow is large, the lane changing behavior may seriously affect the driving of the traffic flow. Speed, reducing road capacity, unreasonable lane changing behavior may even cause serious traffic accidents
