Intelligent vehicle navigation system and method based on perception and autonomous calculation positioning navigation

Abstract

The invention discloses an intelligent vehicle navigation system based on perception and autonomous calculation positioning navigation, and the system comprises an information storage module, a motor drive module, a positioning module, a perception module and an interaction communication module, wherein the information storage module, the motor drive module, the positioning module, the perception module and the interaction communication module are respectively connected with a central processor. The central processor, the drive module and the positioning module are used for achieving the positioning navigation and movement of an intelligent vehicle, and the perception module is used for achieving the stable control of the intelligent vehicle. The interaction communication module is used for achieving man-machine interaction. The navigation process comprises the steps: obtaining a generalized electronic map; obtaining initial position information of the vehicle and carrying out the positioning correction; obtaining the current position coordinates of the vehicle and target coordinates; and dynamically planning a driving path. According to the invention, the independent perception and feedback control of wheels are employed for the path of a local region and the control optimization, and the overall path planning and navigation are still implemented through a path planning algorithm. The system can monitor and distribute tasks in real time through a cellphone or tablet PC and a wireless network, and achieves the visualization and the real-time control.

Description

technical field

[0001] The invention relates to an autonomous positioning and automatic guided vehicle system. Background technique

[0002] Automatic Guided Vehicle (AGV, Automatic Guided Vehicle) refers to a transport trolley with electromagnetic or optical guidance devices, capable of walking along a predetermined route, with running and parking devices, safety protection devices, and various transfer functions.

[0003] According to different guidance methods, automatic guided vehicles can be divided into fixed path guidance and free path guidance. Fixed path guidance refers to the information medium used for guidance on a fixed route, and the automatic guided vehicle is guided by detecting its information, such as electromagnetic guidance, optical guidance, and tape guidance. The free path guidance means that the automatic guided vehicle can change the driving route at will according to the requirements. This guidance method is to store the working environment informa...
