Abstract

The invention provides a lane changing path planning method and device, an intelligent driving automobile and a storage medium, and relates to the technical field of intelligent driving control. The lane changing path planning method comprises the following steps: after obtaining road information of a target vehicle in a driving process, generating a pre-lane changing path under a lane coordinate system according to the road information and driving state information of the target vehicle; and mapping the pre-lane-changing path to a map coordinate system to obtain a target lane-changing path which can be used for guiding a target vehicle to change a lane. On one hand, safe, comfortable, efficient and intelligent lane changing under different vehicle speeds, different lane widths and different road curvatures is achieved. On the other hand, in the lane changing process, due to the fact that the lane changing compression ratio is adjustable, compared with a traditional path changing method, on the basis that tangential continuity and curvature continuity are guaranteed, the track is slow and adjustable, and a private lane changing style can be configured; the lane changing track is smooth, and the time and space consistency is good.

Description

technical field [0001] The present invention relates to the technical field of intelligent driving control, in particular to a lane-changing path planning method and device, an intelligent driving vehicle and a storage medium. Background technique [0002] Intelligent driving is the product of the deep integration of the automotive industry with new-generation information technologies such as artificial intelligence and high-performance computing platforms, and is an upgrade of the automotive industry. More and more automobile OEMs, suppliers, and technology companies are shifting their research and development focus to automotive intelligent driving technology, taking advantage of their respective advantages, seizing opportunities for industrial upgrading, and entering the autonomous driving industry. [0003] Due to the complexity and challenge of lane-changing scenarios in autonomous driving are much higher than those in lane-keeping conditions, there are few designs invo...
