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.
本发明公开了一种于加速车道对车速进行个性化引导的装置,包括视觉摄像头、数字图像处理器、毫米波雷达、数据处理器和显示屏。还公开了引导方法,视觉摄像头采集进入加速车道的车辆信息,数字图像处理器对该车辆信息进行处理得车型信息;毫米波雷达采集汇入车辆车速、毫米波雷达与汇入车辆的距离、行车道上后车速度、后车与毫米波雷达的距离;数据处理器对毫米波雷达采集的信息进行处理,得汇入车辆的剩余距离以及汇入车辆和后车的相对距离;数据处理器还接收到数字图像处理器发送来的车型信息,经过与数据库中最优速度曲线进行对比,确定差异等级,并根据差异等级通过显示屏输出提醒信号。本发明对汇入车辆进行个性化引导,降低了汇入风险。
