Automatic driving underlying system based on UWB positioning technology

Abstract

The invention provides an automatic driving underlying system based on a UWB positioning technology, which can overcome the defects of a visual perception system and improve the accuracy of automatic driving positioning, and comprises a cloud server, a UWB license plate and a vehicle main control module arranged on a vehicle, and a plurality of roadside units arranged on the roadside, the UWB license plate is used for sending UWB license plate data to the road side unit in real time; the road side unit is used for packaging and uploading UWB license plate data and the own number to the cloud server; the cloud server retrieves vehicle information according to a license plate number in the UWB license plate data, retrieves roadside unit position information according to a roadside unit number, finally establishes a mathematical model according to the vehicle information, the roadside unit position information and the UWB license plate data, determines the position and direction of a vehicle, performs path planning, generates a vehicle driving instruction of each vehicle, and sends vehicle driving instruction to the vehicle main control module; and the vehicle main control module is used for controlling the vehicle to run according to the vehicle running instruction.

Description

technical field [0001] The invention belongs to the technical field of automatic driving, and in particular relates to an underlying system of automatic driving based on UWB positioning technology. Background technique [0002] In the prior art, unmanned vehicles use on-board sensors to perceive the surrounding environment of the vehicle, and control the steering and speed of the vehicle according to the road, vehicle position and obstacle information obtained through perception, so that the vehicle can drive on the road. [0003] But there are still many problems in this perception system, the first is the problem of visual recognition. Because visual recognition has extremely strict requirements on light, without suitable light, the visual system cannot recognize the required information, especially at night, the car must be supplemented with lighting, and the image is still blurred after the supplementary light. In order to improve Clarity, often will use a more expensiv...

Problems solved by technology

[0003] However, there are still many problems in this perception system, the first is the problem of visual recognition

Because visual recognition has extremely strict requirements on light, without suitable light, the visual system cannot recognize the required information, especially at night, the car must be supplemented with lighting, and the image is still blurred after the supplementary light. In order to improve Clarity, often will use more expensive camera

Secondly, in order to perfectly perceive the surrounding environment, various sensors must be installed on the car, which greatly increases the cost of car production

[0004] The current unmanned driving technology often writes related programs into the controller inside the car. The amount of calculation is too large, and system loopholes are prone to occur. It is difficult to guarantee that there will be no errors in one day, causing safety hazards.

Therefore, the existing vehicle-mounted sensing system solutions have great limitations.
