Abstract

Embodiments of the present application provide a method, apparatus, device, and readable storage medium for planning a travel path. The method includes: acquiring current road environment data in front of the vehicle; setting pass candidate points according to current road environment information and a driving strategy; and determining a current optimal passable path according to the pass candidate points. Setting pass candidate points according to the current road environment information and driving strategy, and then determining the current optimal passable path according to the pass candidate points, can effectively reduce the number of pass candidate points set in all areas directly in front of the unmanned vehicle in the prior art, which is computationally unreachable. The calculation amount of the passing path, thereby reducing the calculation amount of the passing path planning, improving the planning speed of the passing path, and considering the driving strategy of the unmanned vehicle when setting the passing candidate points, so that the planned path can be very good. Coupled driving strategies.

Description

Technical field [0001] The present application relates to the field of driverless technology, and more particularly to a planning method, apparatus, device, and readable storage medium of a pass path. Background technique [0002] With the development of computer technology and artificial intelligence, unmanned vehicles (referred to as unintro) have broad application prospects in transportation, military, logistics warehousing, daily lives. Driving techniques mainly include perception of environmental information, smart decisions of driving behavior, no collision path planning, and portions of motion control of vehicles. Path Planning is a key part of unmanned technology, which is based on environmental data of a perceptual system. The vehicle needs to scale a safe and reliable, from the starting position to the target position in a complex road environment. path. [0003] The existing general path planning method is primarily based on a grid algorithm (English: lattice) planning...
