Navigation-based early warning method, terminal devices and server

Abstract

The invention provides a navigation-based early warning method, terminal devices and a server, which is applied to a vehicle early warning system. The vehicle early warning system comprises a first terminal device, a second terminal device and the server. The method comprises the steps that the first terminal device reports the position information of a first vehicle to the server; the position information of the first vehicle is used by the server to determine the status information of at least one second vehicle; the distance between the second vehicle and the first vehicle is within a preset range; the status information, which is transmitted by the server, of at least one second vehicle is received; the second vehicle in the blind zone of the first vehicle is determined, wherein the distance between the second vehicle and the first vehicle is less than safety distance; and when at least one second vehicle is in the blind zone of the first vehicle, and the distance between the second vehicle and the first vehicle is less than safety distance, an early warning alert is issued. According to the embodiment of the invention, the second vehicle can be precisely identified, wherein the distance between the second vehicle and the first vehicle is less than safety distance; and corresponding measures are taken in time to reduce traffic accidents.

Description

technical field [0001] The invention relates to the technical field of electronic navigation, in particular to a navigation-based early warning method, terminal equipment and a server. Background technique [0002] Currently, navigation devices are widely used in vehicles. During the driving process of the vehicle, because the driving speed is generally fast, it is necessary to obtain the road condition information of the driving section in real time through the navigation device, such as the number of vehicles in the section, the driving speed and other information, so that the vehicle driver can according to the current road condition Information is analyzed to improve driving safety. For example, vehicle drivers can perform operations such as turning and decelerating according to the current road condition information. However, due to factors such as complex roads, many intersections, a large number of driving vehicles, and vehicles in motion that do not participate in v...
