Beidou navigation-based sweeping vehicle double-driving-mode control system

Abstract

The invention relates to a Beidou navigation-based sweeping vehicle double-driving-mode control system. The system comprises an intelligent decision-making unit used for coordinating and commanding the driving and the operation of a sweeping vehicle, and provided with a mode switching switch used for selecting a driving mode; an environment sensing unit used for acquiring the road condition information near the periphery of the vehicle body of the sweeping vehicle; a beidou positioning terminal used for providing the positioning and the route navigation for the vehicle; a V2I communication device used for carrying out information interaction with traffic lights, and providing the traffic light time information for the intelligent decision-making unit; a drive-by-wire brake unit used for receiving and executing an unmanned driving mode braking instruction of the intelligent decision-making unit; a drive-by-wire steering unit used for receiving and executing an unmanned driving mode steering instruction of the intelligent decision-making unit; a remote monitoring unit used for receiving the real-time environment information and sending a control instruction to the intelligent decision-making unit; and a battery pack used for supplying power to the whole system. Compared with the prior art, the system has two switchable driving modes, and is accurate in unmanned driving effect.

Description

technical field [0001] The invention relates to the field of unmanned driving, in particular to a dual-driving mode control system for sweeping vehicles based on Beidou navigation. Background technique [0002] The navigation methods of unmanned smart cars can be divided into laser radar navigation, visual navigation, Beidou navigation and so on according to the different sensor forms. Lidar navigation can scan the distance information of roads and obstacles in the direction of the vehicle through laser scanning; visual navigation mainly collects image information of the road ahead through cameras; Beidou satellite navigation system is a satellite navigation system independently developed and operated by China. The satellite positioning information of the vehicle is collected through the Beidou positioning terminal. Compared with other types of navigation methods, the Beidou satellite navigation system is safer to use and has higher positioning accuracy. At present, the Be...

Problems solved by technology

Most of the existing sweeping vehicles use manual driving to ensure the normal work of the sweeping vehicles. There is no complete automatic driving technology applied to the slow-moving vehicles such as sweeping vehicles. With the development of society, the number of motor vehicles on the road increases. The combination of safe driving and efficient operation has become a big problem
