Abstract

The invention relates to a typical bend area seamless communication method under a V2X (Vehicle to Vehicle and Vehicle to Infrastructure) environment, and belongs to the field of traffic information perception and communication. The method comprises the following steps that: extracting people, vehicle, road and environment information in a bend, processing data, establishing a vehicle bend collision avoidance safe distance equation and an attraction factor model; judging whether a relative distance Dr between a front vehicle and a rear vehicle is smaller than the safe distance or not; judgingthe evaluation level of a degree of safety; and according to judgment, determining whether a communication mode is switched or not and whether a collision avoidance system is started or not. By use ofthe method, the influence of multiple factors on the driving operation of a driver is fully considered, a reference basis is provided for the judgment of seamless communication, and travelling safetyis improved.

Description

technical field [0001] The invention belongs to the field of traffic information perception and communication, and mainly relates to a seamless communication method in a typical curve area in a V2X environment. Background technique [0002] Curve driving technology is an important driving technology for the driver. There are obstacles in the curve driving, and people, vehicles and the environment are the four main factors that affect driving safety. There is a delay in the driver's understanding of the instant situation and emergencies entering the curve, which can easily lead to the occurrence of curve driving accidents. In view of this, finding a more effective way of communication and interaction, increasing the data transmission rate, receiving real-time curved road condition information in advance, accurately and comprehensively, and prompting the driver to take corresponding preventive measures will largely avoid traffic accidents. Accidents happen. Therefore, there ...
