Abstract

The invention provides a vehicle travel early-warning method, relating to the field of vehicle safety. The method comprises the following steps: transmitting a first signal containing the traveling state data of the vehicle at the moment; receiving a second wireless signal transmitted to the vehicle directly from other vehicles in a preset range, wherein the second wireless signal contains the traveling state data of other vehicles at the moment; screening exceptional vehicles in exceptional traveling from other vehicles in the preset range according to the traveling state data in the second wireless signal and the preset conditions; only in the existence of exceptional vehicle, calculating the collision probability between the vehicle and the exceptional vehicle, and regarding the exceptional vehicle of which the collision probability with the vehicle exceeds the preset collision probability threshold as a dangerous vehicle; and in the existence of dangerous vehicle, sending an alarm to the driver of the vehicle. By adopting the scheme, the driver can be accurately reminded of possible collision with other vehicles in real time, and false alarm is avoided, so that the occurrence probability of traffic accidents is reduced.

Description

[0001] This application is a divisional application of an invention patent application with the application date of January 26, 2014, the application number 201410039014.4, and the title "A Method for Early Warning of Vehicle Driving". technical field [0002] The invention relates to the field of vehicle safety, in particular to a vehicle running early warning method. Background technique [0003] During the driving process of the vehicle, traffic accidents often occur when the speed of other adjacent vehicles is too fast; especially in the case of high speed, night, poor road conditions, and poor weather conditions (such as foggy, rainy or snowy days) The probability of traffic accidents is greatly increased. For this reason, some schemes have been proposed in the prior art to calculate the collision probability between vehicles based on vehicle GPS position data and other data, and to provide early warning in the case of a relatively high collision possibility.
