Abstract

The embodiment of the present invention provides a driving behavior optimization method and device, which determines the distance between the own vehicle and the adjacent vehicle according to the current position of the own vehicle and the current position of the adjacent vehicle, and determines the headway of the own vehicle in combination with the current speed of the own vehicle ; If the headway of the car is greater than the critical headway, calculate the ratio of the current speed of the car to the preset speed limit value, so as to determine the driving state of the car according to the ratio, and feed back the driving state of the car to the driver , so that the driver can optimize the driving behavior. The method and device can effectively optimize the driving behavior of the driver by monitoring the driving state of the driver in real time without relying on a large number of auxiliary vehicle equipment or roadside equipment, the application cost is low and easy to promote, and can be widely used in road traffic management In the work, it is beneficial to reduce the potential hidden dangers of road traffic accidents, which in turn is conducive to improving the operational efficiency and safety of road traffic.

Description

technical field [0001] The present invention relates to the technical field of intelligent transportation, and more specifically, to a driving behavior optimization method and device. Background technique [0002] With the continuous increase of expressway mileage, the traffic safety situation of expressways is also relatively severe. In recent years, traffic accidents on expressways have accounted for a large proportion of all road traffic accidents and are showing an upward trend. At the same time, due to the high speed of vehicles on expressways, the severity of injuries in traffic accidents is often relatively large. According to the analysis of the causes of expressway traffic accidents, most of them are traffic accidents where the following car is too close or the driving speed is too high, so that the rear car cannot stop safely when the front car brakes and the rear-end collision occurs. [0003] In view of this, it is urgent to provide a driving behavior optimizati...
