Abstract

The invention discloses a trajectory deviation rectification method and device and an automatic driving guide vehicle. The trajectory deviation rectification method comprises the steps: when it is detected that an autonomous guide vehicle is in a deviation route state, determining the driving wheel speed and the driving wheel center distance value of the vehicle; based on the driving wheel speed and the driving wheel center distance value, determining a trajectory deviation rectification parameter; and controlling the autonomous guide vehicle to perform deviation rectification operation according to the trajectory deviation rectification parameter so as to return to a preset trajectory route. According to the invention, the technical problem that in the prior art, wheels of an automatic guided vehicle are prone to slipping in the navigation process, and derailment of the vehicle is prone to being caused is solved.

Description

technical field [0001] The invention relates to the technical field of vehicle control, in particular to a track deviation correction method and device, and an automatic driving guided vehicle. Background technique [0002] In related technologies, a large number of automatic guided vehicles have begun to be used in logistics transportation and factory automation production. At present, after planning the driving route of the automatic guided vehicle, it will control the automatic guided vehicle to navigate according to the planned route. The navigation methods of the automatic guided vehicle include : Tape navigation, two-dimensional code inertial and SLAM (referring to real-time positioning and map construction) navigation. At present, the automatic guided vehicle is controlled by visual SLAM navigation, so it has high flexibility, high automation, and high obstacle avoidance. favored by more and more fields. However, if the current visual SLAM navigation method operates ...
