Autonomous driving vehicle lane selection method and system, and vehicle

Abstract

The invention provides an autonomous driving vehicle lane selection method and system and a vehicle. The autonomous driving vehicle lane selection method comprises the steps of obtaining road information ahead of the vehicle; judging whether the road ahead of the vehicle is a ramp narrowing road according to the road information; if so, before the vehicle drives into the ramp narrowing road, selecting a target lane from the ramp narrowing road according to a driving rule; and controlling the vehicle to change lanes to the target lane. According to the autonomous driving vehicle lane selectionmethod provided by the invention, the priority driving target lane of the autonomous driving vehicle can be planned when the autonomous driving vehicle drives on the expressway ramp, thereby avoidingthe danger of collision with other vehicles caused by a large lateral deviation of the autonomous driving vehicle driving on the ramp due to inaccurate positioning of a map; and the target lane selection planning mode conforms to the driving habit of people.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a lane selection method, system and vehicle for an automatic driving vehicle. Background technique [0002] Self-driving cars refer to: through the cooperation of visual sensors, laser radars, millimeter-wave radars, ultrasonic radars, monitoring devices and positioning systems, etc., it is possible to automatically operate the vehicle without any active human operation and save the driver from the heavy load. Freed from vehicle operation. It uses technologies such as computers, sensors, information fusion, communication, artificial intelligence and automatic control to plan vehicle travel routes in real time and arrive at preset locations. [0003] If the self-driving vehicle encounters road changes during driving, such as (when there are obstacles in front of the road, the ramp becomes narrower, the ramp becomes wider, the ramp diverges, and the ramp merges and intersects)...

AI Technical Summary

Problems solved by technology

[0003] If the self-driving vehicle encounters road changes during driving, such as (when there are obstacles in front of the road, the ramp becomes narrower, the ramp becomes wider, the ramp diverges, and the ramp merges and intersects), it needs to change lanes. In related technologies, according to the surrounding The speed and distance of the vehicle or obstacle can be used to judge whether it is possible to change lanes. However, due to road changes, if the driving path is not planned reasonably, it may lead to frequent lane changes, which poses a high safety hazard.
