Embodiment Construction

[0022] specific implementation plan

[0023] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

[0024] The lane selection system for self-driving vehicles of the present invention includes a vehicle-mounted terminal and an information service terminal, and the vehicle-mounted terminal includes a data collection module and a path planning module, such as figure 1 shown.

[0025] The data collection module should be able to collect vehicle location information and vehicle speed information, and send them to the information service terminal.

[0026] The information service terminal includes an information processing module. By receiving the vehicle speed information of the vehicle that can send data information, the traffic flow speed information in the whole area is obtained to form a real-time traffic flow speed information database. speed And send it to the path planning module of the vehicle terminal according to...

Abstract

The invention provides a lane selection method for autonomous driving. The processing steps are as follows: 1, the initial point, the ending point and the driving area of a road path are determined, and each road section and each lane are divided; 2, the vehicle speed of each lane is acquired, the average vehicle speed is calculated, and a real-time information database is built; 3, the average vehicle speed is sent to a vehicle-mounted terminal, and lane-level road path planning is carried out based on the shortest time; 4, when the changed real-time average vehicle speed enables the planned driving lane to be changed, according to the average speed difference between the lanes and the distance information between the vehicle position and a front intersection, whether to change a lane for driving is considered comprehensively; and 5, if lane changing can be carried out, the newly-planned lane is tracked for driving, and if not, the originally-planned lane is used for driving. Lane selection is carried out according to the real-time vehicle flow speed and the position information between the vehicle and the intersection, the driving lane is corrected automatically in real time, and the vehicle can be autonomously driven to avoid a congested road.

Description

technical field [0001] The invention belongs to the field of information fusion technology and intelligent information processing technology, and in particular relates to a lane selection method for an automatic driving vehicle. Background technique [0002] With the development of driver assistance technology, autonomous driving technology is increasingly becoming a topic of concern. Autonomous vehicles have higher requirements for path planning than traditional vehicles, and they need to be accurate to the lane level. At the same time, how to actively avoid congested road sections according to real-time traffic flow conditions has become a new problem faced by the autonomous vehicle path planning system. [0003] Patent Document 1 (CN104880193A) discloses a lane-level navigation system and its lane-level navigation method. According to vehicle positioning information and destination information, according to the current vehicle congestion index and the average driving spe...
