Safety warning method based on vehicle speed detection

Abstract

The invention discloses a safety warning method based on vehicle speed detection. The safety warning method comprises the steps of obtaining the position of a target vehicle and the first speed of thetarget vehicle within the preset range of the position where a user vehicle is located; calculating the time when the target vehicle arrives at the position of the user vehicle according to the position of the target vehicle and the first speed of the target vehicle; when the time when the target vehicle arrives at the position where the user vehicle is located is smaller than a preset first timethreshold value, sending a first safety prompt to the target vehicle; when the time that the target vehicle arrives at the position where the user vehicle is located is smaller than a preset second time threshold value, obtaining the second speed of the target vehicle within the preset range of the position where the user vehicle is located, wherein the first time threshold value is larger than the second time threshold value; judging whether the target vehicle decelerates or not according to the first speed of the target vehicle and the second speed of the target vehicle; and when it is determined that the target vehicle does not decelerate, sending a second safety prompt to the target vehicle.

Description

technical field [0001] The invention relates to the technical field of driving safety, in particular to a safety warning method based on vehicle speed detection.
