The invention provides a vehicle turning and overspeed early warning method and a vehicle turning and overspeed early warning system. A road side unit is placed at a curve and periodically broadcasts curve information outwards, and a vehicle-mounted terminal judges whether a vehicle is driven to the curve or not in advance according to own vehicle information and the received curve information; if so, a prompt of a distance to the curve and a speed limit is given in advance; if it is detected that the vehicle is driven into the curve, a curve speed limit prompt is given, whether the vehicle is overspeed or not is detected in real time, and if so overspeed early warning is given out to remind a driver to drive at a safe speed; and when it is detected that the vehicle runs out of the curve, early warning is relieved. By the adoption of the technical scheme, the limiting speed at the curve can be given in advance, the curve entering and exiting of the vehicle can be efficiently and reliably judged, early warning of characters and sounds is given when the vehicle is overspeed, and a selectable simple and convenient scheme is provided for auxiliary driving safety application of the Internet of Vehicles.
本发明提供一种车辆过弯超速预警方法和车辆过弯超速预警系统,通过弯道处放置一个路侧单元,其周期性地向外广播弯道信息,车载终端根据自身车辆信息和收到的弯道信息提前判断车辆是否驶向该弯道;如果是,则提前给出到弯道的距离和限速提示;如果检测到车辆驶入弯道,则给出弯道限速提示并实时检测车辆是否超速,若超速则发出超速预警,提醒驾驶员以安全的速度驾驶;当检测到车辆驶出弯道时,解除预警。采用本发明的技术方案,能够提前给出弯道处的限制速度且能够高效可靠地判断出车辆的进弯和出弯,当车辆超速时给出文字和声音的预警,为车联网的辅助行车安全应用提供了一个可选的简便方案。
