Vehicle information interaction system, method for determining position of rear vehicle and automobile

Abstract

The invention provides a vehicle information interaction system, a method and device for determining the position of a rear vehicle and an automobile, and relates to the field of automobile control. The system comprises a visible light wireless communication device, wherein the visible light wireless communication device comprises a transmitting end and a receiving end; the visible light wireless communication equipment takes infrared light as a light source, is independently mounted at the head part and the tail part of the vehicle, and performs data interaction with a whole vehicle controller of the vehicle through a controller of the visible light wireless communication equipment; a plurality of receiving ends are arranged at the tail of the vehicle and are distributed in the horizontal direction. According to the invention, the infrared light is used as the light source, and the vehicle lamp of the vehicle is not used as the light source, so that the efficiency and accuracy of information interaction between vehicles by the visible light wireless communication equipment are improved, and the position of the rear vehicle relative to the vehicle can be accurately determined. The vehicle information interaction system provided by the embodiment of the invention has extremely high practical value.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a vehicle information interaction system, a method and a device for determining the position of a rear vehicle, and an automobile. Background technique [0002] LiFi (Light Fidelity, visible light wireless communication) technology is a new wireless transmission technology that uses visible light waves (such as the light emitted by a light bulb) for data transmission. Invented by Professor Harald Hass. [0003] At present, with the development of autonomous driving technology, the communication between vehicles is particularly important to the driver's driving safety. Although the existing millimeter-wave radar, lidar and on-board camera can identify the distance between vehicles, they cannot provide information for the distance between vehicles. Detailed location information is obtained from the opponent's vehicle, and the recognition accuracy is limited and the cost is high. ...

AI Technical Summary

Problems solved by technology

However, the vehicle lights need to take into account the lighting function when communicating. In this case, due to the illumination range of the lights and the influence of the use environment, the efficiency and accuracy of LiFi technology to achieve information interaction between vehicles are low, and if there are When multiple vehicles exist, the relative position of the rear vehicle cannot be accurately judged by LiFi technology
