A method for controlling operation of an intelligent vehicle navigation (IVN) system includes a system controller receiving path planning data for a desired route of a vehicle, and using the path planning data to identify a low/connectionless (LNC) area with limited/no wireless service within the desired route. The IVN system retrieves historical trip data including a duration of time traversing the LNC region for a statistically significant number of previous trips traversing the LNC region; the IVN system constructs a probability distribution of these travel durations. The IVN system tracks a time interval during which no wireless signal is received from the vehicle after the vehicle outputs the last wireless signal before entering the LNC area. A driving event is predicted in response to the no-signal time interval exceeding a predetermined threshold within the probability distribution. The system controller responds to the predicted driving event by transmitting the alert to the third party entity.
用于控制智能车辆导航(IVN)系统的操作的方法,包括:系统控制器接收车辆的期望路线的路径规划数据,以及使用该路径规划数据识别在期望路线内具有有限/没有无线服务的低/无连接(LNC)区域。IVN系统检索历史行程数据,包含对于统计显著数量的穿过该LNC区域的先前行程而言穿过LNC区域的持续时间;IVN系统构造这些行程持续时间的概率分布。IVN系统跟踪时间间隔,在所述时间间隔期间,在进入LNC区域之前车辆输出最后一个无线信号之后,没有无线信号从车辆接收。响应于无信号时间间隔超过概率分布内的预定阈值,预测驾驶事件。系统控制器通过将警报传输到第三方实体而对预测驾驶事件做出响应。
