Abstract

The invention discloses a lane departure judging and early warning system for an automobile on a high-way. The lane departure judging and early warning system comprises distance measuring radars, an embedded single-chip computer and an alarm. According to the lane departure judging and early warning system disclosed by the invention, lane departure is judged for a travelling vehicle according to a relative distance between the vehicle and a guardrail; the structure is simple and reliable, and is not liable to be disturbed or influenced by factors, such as weather, road surface conditions, signs and markings; and a lane departure behavior of the driven vehicle, caused by unconsciousness of a driver, such as distraction and tiredness, can be identified in time, and an alarm is given to prompt the driver. The occurrence of lane departure accidents can be reduced and avoided effectively, and the driving safety of the driver is improved.

Description

technical field [0001] The invention relates to the field of on-vehicle control, in particular to a judgment and early warning system for vehicles departing from a lane on an expressway. Background technique [0002] With the continuous development of automobile technology, the functions of auxiliary driving systems for automobiles have been continuously expanded, which has greatly improved the safety factor and comfort of vehicles. Lane departure systems have become one of the high-tech systems currently being developed by most vehicle manufacturers. First, the system can improve the safety factor of the vehicle, effectively prevent driver distraction and fatigue driving, etc., so as to achieve the purpose of preventing traffic accidents. However, the structure of the current lane departure system is relatively complicated and the cost is relatively high. [0003] Therefore, the above-mentioned problems of the prior art need to be solved urgently. Contents of the inventi...
