Backing up assisting system of trailer

Abstract

The invention discloses a backing up assisting system of a trailer. The backing up assisting system comprises a sensor module, a data processing module and an information display prompting module, wherein the sensor module is composed of a camera, a radar and a potentiometer; the data processing module is composed of a data input module, a central processing unit and a video segmentation device; the information display prompting module is composed of a display screen and a buzzer; a transmitting end of the radar, an output end of the camera and the output end of the potentiometer are connected with an input end of the data input module respectively; the output end of the data input module is connected with the input end of the central processing unit; the output end of the central processing unit is connected with the input end of the video segmentation device; the output end of the video segmentation device is connected with the display screen; the output end of the central processing unit is connected with a positive electrode of the buzzer and a negative electrode of the buzzer is grounded. According to the backing up assisting system disclosed by the invention, data acquisition is realized through utilizing a radar plus steering engine innovative approach and reasonably matching and arranging the radar and the camera; a driver can be more effectively assisted by adopting screen segmentation and screen color change, and driving safety is guaranteed.

Description

technical field [0001] The invention belongs to the field of intelligent detection and early warning of driving, and relates to a trailer reversing auxiliary system. Background technique [0002] With the increasing requirements for vehicle driving safety, in terms of reversing assistance, technologies such as vehicle distance measurement technology, image sensing technology, video transmission technology, and safety warning technology have been more and more widely used in vehicles. Reversing auxiliary devices composed of cameras, reversing radars, and display screens have been widely used in passenger vehicles and some commercial vehicles, especially family cars. For drop-and-hook transport vehicles, the joint between the tractor and the trailer is not fully constrained when reversing, and it is difficult for the driver to control the direction of the trailer when reversing. At the same time, the angle of intersection between the tractor and the trailer causes blind spots ...

AI Technical Summary

Problems solved by technology

[0004] However, there are problems in the following aspects in the prior art: the combination, installation position and installation method of the sensors are the main factors affecting the comprehensiveness of information detection, and the prior art has not given sufficient consideration; the display mode of distance information and image information on the display screen It is related to the driver's accurate and fast capture of the response to the situation in the dangerous area. In the synchronous display of information, the existing technology cannot be quickly captured by the driver when a certain direction is a dangerous area; most of the existing technologies provide More detailed reversing information is the goal, and the decision-making still depends entirely on the driver's experience and technical level and cannot be given to the driver as a reference by providing direction prompts
