A method for reminding a user to change lanes

Abstract

The invention relates to the technical field of a vehicle-mounted system, solves the problem that, in the prior art, when an accident occurs ahead, a driver cannot know the reason for the road congestion ahead but only gets stuck in traffic, and provides a method for reminding a user to change lanes. The method comprises the following steps: when a first vehicle meets an accident ahead and an automobile data recorder is started to record the accident, a first vehicle-mounted server of the first vehicle determines the position of the first vehicle according to vehicle positioning information; the first vehicle-mounted server sends the position information to a cloud server; the cloud server determines a second vehicle, a second vehicle-mounted server of which is started, in the vehicles in a preset range behind the first vehicle according to the position information of the first vehicle; the cloud server receives the record of the accident and sends the record to the second vehicle-mounted server of the second vehicle; the record is played through a video displayer of the second vehicle; and the cloud server generates a reminding information, and sends the reminding information to an intelligent terminal of the user, the vehicle of which is about to drive in the preset range.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted systems, in particular to a method for reminding users to change lanes. Background technique [0002] With the rapid growth of China's economy, the number of cars in China is increasing at a rate of millions every year, and cars have entered thousands of households. There are more and more functions in the car. However, when the car is driving, when there is an accident or obstruction in front, the vehicles behind cannot see it and can only be blocked by the vehicles in front. In this way, Passengers or the driver in the rear will be irritable and so on. [0003] Therefore, when there is an accident in the front in the prior art, the rear vehicle can only be blocked in the rear, and the driver can't know what causes the phenomenon that the road conditions are congested in the front, and can only be blocked on the road. Contents of the invention [0004] The embodiment of the present in...
