Problems solved by technology

[0002] Traveling by car has become a trend. When traveling by car, the driver will inevitably have problems such as fatigue driving or inattention during the driving process, which will cause the vehicle to deviate from the normal driving lane and easily collide with other vehicles. Big security risk
[0003] In addition, compared with the past, more and more people have obtained driver's licenses, resulting in a lot of novice drivers. Novice drivers are often relatively unfamiliar with their skills, unable to realize whether their driving trajectory is correct in time, and may just be distracted for a while. lead to traffic accidents

Abstract

The invention discloses a mobile terminal-based lane deviation forewarning method and system, comprising: step S10, acquiring boundary line data of a lane which a vehicle is currently on; step S20, calculating an axis position of the lane, a forewarning line position and an axis position where the vehicle is currently located, according to the boundary line data and current body width of the vehicle; step S30, judging whether a distance between the axis position where the vehicle is currently located and the forewarning line position reaches a forewarning value or not, if yes, executing step S40, and if not, executing step S10; step S40, sending out driving path forewarning information.When a vehicle departs a lane and potential safety hazards are posed, a driver is reminded in time to adjust a driving path of the vehicle, thus avoiding traffic accidents.

Description

technical field [0001] The invention relates to the field of early warning of mobile terminals, in particular to a method and system for early warning of lane departure based on mobile terminals. Background technique [0002] Traveling by car has become a trend. When traveling by car, the driver will inevitably have problems such as fatigue driving or inattention during the driving process, which will cause the vehicle to deviate from the normal driving lane and easily collide with other vehicles. greater safety hazard. [0003] In addition, compared with the past, more and more people have obtained driver's licenses, resulting in a lot of novice drivers. Novice drivers are often relatively unfamiliar with their skills, unable to realize whether their driving trajectory is correct in time, and may just be distracted for a while. It will lead to the occurrence of traffic accidents. Contents of the invention [0004] The purpose of the present invention is to provide a lan...
