Embodiment Construction

[0044] The invention helps to solve the problem that motor vehicle drivers cannot timely grasp the driving status of the vehicle in front or the current road condition information due to visual limitations, including distance and obstacles, and assists the road driving of the motor vehicle. The invention satisfies the driver's demand for real-time traffic information in front during the driving process of the vehicle through vehicle position information perception and prediction and information dissemination and display through inter-vehicle communication, and pre-brakes for the driver and detours in advance Provide a reference to improve the driving safety of drivers, and can significantly reduce road congestion or alleviate road congestion. The present invention transmits the vehicle GPS information obtained by the vehicle to the surrounding vehicles through the vehicle wireless transmission equipment, and the vehicles that receive the position information, through calculatio...

Abstract

The invention discloses a vehicle density sensing system and a vehicle density sensing method based on inter-vehicle communication. By sensing and predicting the vehicle position information, spreading and displaying of information is realized based on the inter-vehicle communication, the demand of a driver on the front real-time traffic information in the vehicle running process is satisfied, and reference is provided for the driver to brake and move around in advance, thus the driving safety of the driver is improved, and the road congestion can be obviously reduced or alleviated. According to the invention, vehicle GPS (Global Position System) information obtained by a vehicle is spread to the surrounding vehicles via a wireless vehicle transmission device, each vehicle which receives the position information can known the positions and the density information of other vehicles in a certain range around by performing calculation and comparison, so that an auxiliary reminding function for judging of the driver in the driving process is realized.

Description

technical field [0001] The invention belongs to the technical field of network communication, relates to a method for monitoring motor vehicle running conditions or current road conditions, and relates to a vehicle density sensing system based on inter-vehicle communication and a sensing method thereof. Background technique [0002] With the development of society and economy, the popularity of vehicles is getting higher and higher, and driving has become the choice of many people. During the driving process, if the driver can understand the conditions of the surrounding vehicles, he can make predictions and reduce the occurrence of accidents. At the same time, understanding the traffic conditions of vehicles on nearby roads can help drivers choose roads and reduce road congestion. It can be seen that an excellent vehicle density sensing method can help drivers drive better. [0003] Several existing vehicle perceptions are mainly reflected in the following schemes: 1) The...
