AI Technical Summary

Problems solved by technology

However, traditional motion planning operations mainly estimate the difficulty of completing a given path from the curvature and velocity of the path, without considering the characteristic differences of different types of vehicles
In general, the same motion planning and control is applied to all types of vehicles, which may not be accurate and smooth in some cases

Abstract

In one embodiment, unmanned control is provided for the unmanned vehicle to change from a source lane to a target lane. Using the topology map, select a reference node in the source lane. With respect to the reference node, determine in the source lane the earliest node at which it is first possible for the vehicle to change lanes, and determine in the source lane the last node after which it is no longer possible to change lanes. Determines the range of source lanes in which the vehicle can change lanes.

Description

Technical field [0001] Embodiments of the present disclosure generally relates to the operation of unmanned vehicles. More specifically, embodiments herein relate to the use of the vehicle based on the lane change guidance to operate unmanned FIG. Background technique [0002] Vehicle operating in an autonomous mode (for example, unmanned) can be occupants, especially the driver freed from some of the responsibilities associated with driving in. When operating in the autonomous mode, the vehicle onboard sensors may be used to navigate to various locations, thereby allowing the vehicle to travel or, in some cases without any passengers with minimal human interaction. [0003] Motion planning and control is the key to the operation of unmanned. However, the conventional motion planning mainly operating speed and estimated from the curvature of the path to complete a given path difficulty, without considering the difference in characteristics of different types of vehicles. Typicall...
