Judgment method for preventing sudden lane change of back vehicle after overtaking passenger vehicle and device

Abstract

The present invention discloses a judgment method for preventing the sudden lane change of a back vehicle after overtaking a passenger vehicle and a device. The device comprises an image acquisition module, an LCD monitor, an alarm module, a storage hard disk and a digital signal processor. The method comprises the following steps that a lane image is collected through a camera, firstly whether a vehicle in a left side lane is in an overtaking state is judged, on the above condition, combined with a front lane vehicle travelling state, if only a left front side lane in front lanes has a vehicle or the distance of the vehicle in the left front side lane is smaller than the distance between the front vehicle in an own lane and an own vehicle, which means that the vehicle which overtakes the own vehicle has the possibility of lane change, a system device emits an alarm, and the image of the lane change overtaking vehicle is stored in the storage hard disk at the same time. According to the device and the method, the traffic accident in the overtaking and lane change process of the back vehicle can be effectively prevented, the technical content and ability of road passenger transport safety management are improved practically, and the purpose of improving native road passenger transport safety and the operational efficiency of road passenger transport and maintaining sustainable development is achieved.

Description

technical field [0001] The invention relates to the field of passenger vehicle driving safety, in particular to a method for judging passenger vehicles from overtaking and changing lanes and an early warning device thereof. Background technique [0002] In recent years, with the rapid development of my country's road transport industry, road traffic accidents have also remained high, causing a large number of personal casualties and property losses, especially for each large-scale road passenger vehicle traffic accident, causing even greater losses. The impact on society is also particularly serious. How to effectively control or eliminate the occurrence of passenger car unsafe accidents is becoming more and more urgent. [0003] As we all know, the driving behavior of bus drivers is the primary condition to ensure the safety of passenger vehicles. Through careful analysis of the causes of highway passenger traffic accidents, we found that quite a few of them are directly o...

Problems solved by technology

Through careful analysis of the causes of highway passenger traffic accidents, we found that quite a few of them are directly or indirectly related to the speeding lane change and lane grabbing of the drivers of the vehicles behind. operation, resulting in conflicts and disputes and traffic accidents such as rear-end collisions, side collisions, and even rollovers

[0004] At present, passenger vehicles only rely on the driver's subjective cognition to make predictions in order to prevent the vehicle behind from overtaking and suddenly changing lanes. Changing lanes, as a bus driver, it is difficult to grasp the intention of overtaking vehicles; second, in the face of illegal overtaking behavior by overtaking drivers, in many cases, bus drivers are forced to adopt emergency measures and cannot take effective measures in advance; third After the accident, it cannot provide effective and intuitive judgment basis for the traffic control department
