The invention belongs to the technical field of automobile active safety, and particularly relates to a prompting device based on vehicle navigation data sharing and a conflict prompting and early warning method. Through cooperation of the satellite positioning navigation host system, the Bluetooth data acquisition module and the cloud data processing platform, vehicle information is accurately acquired and analyzed, conflict risks are accurately judged, and the accident rate is effectively reduced. Because the driver looks at deceleration due to uncertain intention of the opposite side and causes congestion, the method is adopted for early warning, and the driver is informed of the passing direction of the vehicle and the conflict risk level in advance. When no conflict direction risk exists, the driver is slightly reminded, so that the driver does not need to decelerate; when low and medium risk conflicts exist and the vehicle intention is clear or the coping time is sufficient, the reasonable prompt also avoids excessive deceleration, so that the vehicle can stably pass through the intersection, parking is reduced, the traffic capacity of the intersection is improved, traffic jam is relieved, and the utilization efficiency of road resources is optimized.

    本发明属于汽车主动安全技术领域,具体涉及一种基于车辆导航数据共享的提示装置及冲突提示与预警方法。本发明通过卫星定位导航主机系统、蓝牙数据采集模块与云端数据处理平台的配合,精确采集和分析车辆信息,精准判断冲突风险,有效降低了事故发生率。由于过往驾驶员因不确定对方意图而观望减速,造成拥堵,采用该方法进行预警,提前告知驾驶员对车的通行方向和冲突风险等级。当无冲突方向风险时,轻微提醒驾驶员,使其无需减速;存在低、中风险冲突且对车意图较明确或有充足应对时间时,合理提示也避免了过度减速,从而保证车辆稳定通过路口,减少停车,提高了路口通行能力,缓解了交通拥堵,优化了道路资源利用效率。
