A device and method for personalized guidance of vehicle speed in an acceleration lane

Abstract

The invention discloses a device for individually guiding vehicle speed in an acceleration lane, which comprises a visual camera, a digital image processor, a millimeter-wave radar, a data processor and a display screen. The guidance method is also disclosed. The visual camera collects the vehicle information entering the acceleration lane, and the digital image processor processes the vehicle information to obtain the vehicle type information; the millimeter-wave radar collects the speed of the incoming vehicle, the distance between the millimeter-wave radar and the incoming vehicle, and the driving speed. The speed of the rear vehicle on the road, the distance between the rear vehicle and the millimeter-wave radar; the data processor processes the information collected by the millimeter-wave radar, and obtains the remaining distance imported into the vehicle and the relative distance between the imported vehicle and the rear vehicle; the data processor also receives The model information sent by the digital image processor is compared with the optimal speed curve in the database to determine the difference level, and a reminder signal is output through the display screen according to the difference level. The present invention provides personalized guidance to incoming vehicles, reducing the risk of incoming vehicles.

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...

But this process is often more difficult for novice drivers

In addition, at this stage, the quality of drivers in our country is uneven. Some drivers do not accelerate or observe when they merge, but they force them to merge. At the same time, this may also endanger the driving safety of vehicles on the main lane.
