The invention discloses a mountainous area curve vehicle early warning method based on vehicle-infrastructure cooperation, which comprises the following steps: firstly obtaining real-time information of a vehicle, broadcasting a BSM in real time, then obtaining MAP map information of a road side terminal RSU, carrying out vehicle HV map matching on the vehicle according to the MAP map information, and subdividing the curve into two independent early warning areas, when the vehicle is located in one early-warning area, if a vehicle exists in the other early-warning area, an early-warning mechanism can be triggered, the vehicle on the other side can also trigger the early-warning mechanism at the same time, and the two-way early-warning design can warn a driver of the existence of the vehicle in the opposite direction of the curve in advance; driving risks caused by factors such as inattention, illegal road-occupying driving and a curve sight blind area are effectively reduced, the design not only fits the driving habit and cognitive logic of a driver, but also remarkably reduces the strict requirement for vehicle positioning accuracy in a mountainous area through scientific setting of an early warning area, and the driving safety is improved. The method is more suitable for complex and changeable actual roads and natural environments in mountainous areas.
本发明公开了一种基于车路协同的山区弯道车辆预警方法,该发明先获取车辆的实时信息,并实时广播BSM,再获取路侧终端RSU的MAP地图信息,根据MAP地图信息对车辆进行本车HV地图匹配,将弯道细分为两个独立的预警区域,当本车位于其中一个预警区域时,若另一预警区域内有车辆存在,即会触发预警机制,另一侧的车辆也会同时的触发预警机制,这种双向预警设计,能够提前向驾驶员警示弯道对向车辆的存在,有效减少因注意力不集中、违规占道行驶、弯道视线盲区等因素引发的驾驶风险,此设计不仅贴合驾驶员的驾驶习惯和认知逻辑,还通过预警区域的科学设定,显著降低了对山区车辆定位精度的严格要求,更加契合山区复杂多变的实际道路和自然环境。
