Vehicle driving early warning method

Abstract

The invention provides a vehicle driving early warning method, and relates to the field of vehicle safety. The method includes the steps that a first signal comprising driving state data of a vehicle at the current moment is sent; a second wireless signal directly sent to the vehicle from other vehicles within a preset range is received, wherein the second wireless signal comprises driving state data of other vehicles at the current moment; by the utilization of the driving state data in the second wireless signal and according to a preset condition, abnormal vehicles which are abnormal in driving are screened out from other vehicles within the preset range; only under the condition that the abnormal vehicles exist, is the probability that the vehicle collides with the abnormal vehicles calculated, and the abnormal vehicles are regarded as dangerous vehicles, when the probability that the vehicle collides with the abnormal vehicles is larger than a preset collision probability threshold value; an alarm is given to a driver of the vehicle under the condition that the dangerous vehicles exist. According to the scheme, the driver can be accurately reminded in time that the vehicle probably collides with other vehicles, the false alarm situation is avoided, and the probability of occurrence of traffic accidents is reduced.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to a vehicle running early warning method. Background technique [0002] During the driving process of the vehicle, traffic accidents often occur when other adjacent vehicles are too fast; especially at high speeds, at night, in poor road conditions, and in 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. [0003] The inventors of the present application found that for collision warning, a low false alarm rate and timeliness of warning are very critical indicators. If the false alarm rate is high (such as frequent alarms), it is easy to cause the driver to be t...

This is not convenient, and it is difficult to accurately maintain the ideal distance between vehicles; at the same time, talking on the phone during driving can easily distract the driver's attention and cause traffic accidents
