Abstract

The invention discloses a driving path planning method and device for an intelligent vehicle, belonging to the field of intelligent transportation. Including: obtaining initial lane line information and the driving speed of the smart car, the initial lane line information is determined according to the lane lines in the captured road image, the road image is an image of the driving road in front of the smart car ; According to the pre-calibrated delay time and the driving speed, adjust the initial lane line information to obtain target lane line information; determine a target driving path according to the target lane line information. The invention adjusts the initial lane line information according to the pre-calibrated delay time and driving speed, and can eliminate the lane line information error caused by the delay time, thereby improving the driving safety of the smart car.

Description

technical field [0001] The invention relates to the field of intelligent transportation, in particular to a driving path planning method and device for an intelligent vehicle, and an intelligent vehicle. Background technique [0002] A smart car refers to a vehicle with functions such as automatic recognition of road obstacles, automatic alarm, automatic braking, automatic maintenance of a safe distance, automatic maintenance of a safe speed and / or automatic cruise. Each smart car is equipped with a smart car system, which can plan the driving path in real time according to the actual road environment, and control the smart car to drive according to the planned driving path. Among them, the smart car system generally includes a vision module, a path planning module and an underlying control module. [0003] In related technologies, the planning process of the smart car system for the driving path includes: the vision module takes a road image of the road ahead of the smart ...
