The invention provides an intelligent path finding method and device in a vehicle driving process, and the method comprises the steps: matching a historical driving track of a vehicle with map road network data, and recording all road nodes passed by the vehicle, the length of each road segment, and the consumed driving time; according to a part of the current driving track of the vehicle, combining with the historical driving track to obtain all candidate nodes which may be the end point of the current driving track, calculating the probability that each candidate node becomes the end point by adopting the Bayesian theorem, and taking the candidate node with the maximum probability as the predicted end point of the current driving; acquiring real-time road condition information of a passing road from the driving position of the current vehicle to the predicted terminal point according to the predicted terminal point; and broadcasting the real-time road condition information in batches according to the distance between the obtained real-time road condition information and the driving position of the current vehicle and the importance degree. According to the invention, advanced reminding and real-time road conditions can be provided for a driver, and the driving safety is effectively improved.

    本发明提供的一种车辆行驶过程中的智能探路方法及装置,包括步骤:将车辆的历史行车轨迹与地图路网数据进行匹配,记录车辆经过的所有道路节点、每段道路的长度和耗费的行驶时长;根据车辆当前行驶的部分轨迹,结合所述历史行车轨迹,得到所有可能为当前行驶轨迹终点的候选节点,并采用贝叶斯定理计算每个所述候选节点成为终点的概率,以概率最大的所述候选节点作为本次行车的预测终点;根据所述预测终点,获取当前车辆的行驶位置到所述预测终点的途经道路的实时路况信息;根据获取的所述实时路况信息距离当前车辆的行驶位置的远近和重要性程度对所述实时路况信息进行分批播报。本发明能为司机提供提前提醒和实时路况,有效提高驾驶安全性。
