Problems solved by technology

[0004] 1. Since the AGV of the prior art can only realize simple motion modes such as forward, backward, and spot steering, the switching efficiency is low during the lane switching process
[0005] 2. The lane switching method of the prior art needs to stop the AGV in the current lane first, and cannot realize lane switching in the continuous driving state

Abstract

The invention discloses a navigation method and device for switching lanes, and relates to the technical field of computers. A specific embodiment of the method includes: according to the expected attitude and current attitude of the target vehicle, determining the switching path for the target vehicle to switch from the current attitude to the expected attitude; according to the expected attitude, current attitude and speed parameters of the target vehicle, obtaining the The current attitude is switched to the speed planning trajectory and the displacement planning trajectory of the desired attitude; through the switching path, the speed planning trajectory and the displacement planning trajectory, the left wheel planning speed and the right wheel planning speed of the target vehicle are determined. This embodiment plans the switching path and the speed of the left and right wheels according to the current attitude of the target vehicle, the target attitude and the preset speed parameters, without stopping the target vehicle to achieve smooth lane switching, and improves the efficiency of lane switching.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a navigation method and device for lane switching. Background technique [0002] When a large-scale automated guided vehicle (Automated Guided Vehicle, AGV) is running, some lanes are prone to congestion. If the adjacent lane has a faster passing speed, it is necessary to switch the AGV in the congested lane to the adjacent lane . In order to achieve this goal, in the prior art, it is necessary to first park the AGV in the current lane, and then make the AGV turn 90 degrees in situ, park, go straight, park, and then turn 90 degrees to switch to the adjacent lane. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1. Since the AGV in the prior art can only realize simple motion modes such as forward, backward, and spot steering, the switching efficiency is low during lane switc...
