Embodiment Construction

[0033] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0034] The system can use a device supporting a dedicated short range communication protocol (Dedicated Short Range Communications, DSRC) (hereinafter referred to as a DSRC device). The main hardware is composed of equipment carrying vehicle, DSRC equipment, GPS receiver, antenna, computer, touch screen, etc. The vehicle is the carrier of other equipment and provides 12V DC power supply, and the DSRC equipment is used to complete the reliable sending and receiving of wireless data. Power supply, the DSRC device is connected to the GPS receiver using the RS232 serial port communication and the high-gain diversity fiberglass omnidirectional antenna with the SMA interface. The communication between the DSRC device and the computer is connected through the RJ45 network cable, based on the Socket interface, including the IP address and Port number, ...

Abstract

Disclosed is a lane changing and overtaking assisting method and system based on inter-vehicle communication. The method is characterized in that inter-vehicle communication is built among different vehicles, information support is provided for lane changing and overtaking is provided for drivers of the vehicles through information interaction, the inter-vehicle communication is achieved through short-range communication protocols, when a driver triggers a lane changing and overtaking event, a system identify and process the event and transmits the same to a specified vehicle, and the vehicle received the event restores the event and displays the same as prompt information which can be identified by the driver of the specific vehicle. The system comprises an event identifying module, an event processing module, a wireless communication transceiving module, an event restoring module, a user interface module, and a hardware system formed by a wireless communication device, a positioning device, an antenna, an information processing system and a touch screen. By the method and the system which can be normally used under conditions of bad weather and bad vision, driving safety can be increased effectively.

Description

technical field [0001] The invention belongs to the technical fields of vehicles and information, and relates to a lane-changing and overtaking auxiliary system based on wireless communication between vehicles that can effectively improve driving safety. Background technique [0002] In the traffic accidents caused by changing lanes and overtaking, most of the reasons are due to the inability to recognize the surrounding environment of the vehicle well during the lane changing process, such as the limitation of the visual distance, the influence of severe weather such as heavy fog and heavy rain, etc. , making it very dangerous to change lanes and overtake. At present, there are many existing technologies for assisting lane change and overtaking: 1. Based on video detection technology. However, since the camera is sensitive to illuminance and weather, it is easily disturbed by dust and cannot make good judgments when the vehicle speed is too high, so the lane-changing assis...
