Device and method for personalized guidance for vehicle speed on acceleration lane

Abstract

The invention discloses a device for the personalized guidance for the vehicle speed on an acceleration lane. The device comprises a visual camera, a digital image processor, a millimeter-wave radar,a data processor and a display screen. The invention further discloses a guiding method. The visual camera collects the information of a vehicle entering the accelerating lane, the digital image processor processes the information of the vehicle to obtain the vehicle model information, and the millimeter-wave radar collects the speed of the afflux vehicle, the distance between the millimeter-waveradar and the afflux vehicle, the speed of a rear vehicle on a traffic lane and the distance between the rear vehicle and the millimeter-wave radar; the data processor processes the information collected by the millimeter-wave radar to obtain the remaining distance of the afflux vehicle and the relative distance between the afflux vehicle and the rear vehicle, and the data processor also receivesthe vehicle model information sent by the digital image processor, compares the vehicle model information with an optimal speed curve in a database to determine a difference grade, and outputs a reminding signal through the display screen according to the difference grade. According to the present invention, the personalized guidance is carried out on the afflux vehicles, and the afflux risk is reduced.

Description

technical field [0001] The invention relates to the technical field of traffic safety facilities, in particular to a device and method for personalized guidance of vehicle speed in an acceleration lane. Background technique [0002] With the development of the national economy, the number of car ownership has also increased rapidly. While road traffic safety has been paid attention to, drivers' individual demands on vehicles and roads are also rapidly increasing. Because different drivers have different driving habits and driving styles, traffic safety facilities sometimes cannot meet the needs of different drivers, which in turn affects the driving rhythm of drivers. Drivers will require that the road traffic safety reminder device not only meet the safety requirements, but also meet the driving habits and styles of different drivers in the process of guiding the driver. With the continuous development of intelligent transportation systems, the safety reminder devices for...
