Abstract

The invention discloses a path planning method and device for an autonomous vehicle, a vehicle and a storage medium. The method comprises the following steps: when the distance between the vehicle anda target intersection in pre-acquired road-level navigation information is within a preset distance range, acquiring the lane position of the vehicle in the current road through a forward-looking camera; according to the turning information corresponding to the target intersection in the road-level navigation information and the lane position of the vehicle in the current road, determining whether the vehicle needs to change the lane or not; when it is determined that the vehicle needs to change the lane, controlling the vehicle to drive to the target lane according to the mapping relationship between the vehicle and each lane line, and determining a path from the target lane to the target intersection according to the distance between the target road sign corresponding to the target intersection and the target intersection and the distance between the vehicle and the target intersection determined by the forward-looking camera. The method is high in transportability, low in cost andhigh in accuracy.

Description

technical field [0001] Embodiments of the present invention relate to the field of automatic driving, and in particular, to a path planning method, device, vehicle and storage medium for an automatic driving vehicle. Background technique [0002] With the development of science and technology, autonomous driving technology has become a hot spot in the automotive industry. Path planning is a key technology for the realization of autonomous driving technology. [0003] At present, global path planning in autonomous driving technology is generally realized through high-precision maps and high-precision positioning. Although high-precision maps have high precision and complete elements, they mainly have the following shortcomings: ① The technology is immature, and there is no unified standard for communication protocols and interface specifications; ② The cost of map acquisition is high, and the map acquisition vehicle needs to be equipped with laser radar, cameras, etc. Senso...
