The invention relates to a vehicle working condition prediction method and a vehicle working condition prediction system based on a Wiener random process. The vehicle working condition prediction method comprises the following steps of: 1) clustering vehicle working conditions of different traffic jam conditions based on actually collected vehicle working condition data; 2) taking the average working condition of different traffic jam conditions as a representative working condition of the corresponding traffic jam conditions, and determining a category of the vehicle jam condition in the current time period according to the representative working condition; and 3) based on the determination result of the vehicle congestion condition, superposing the Wiener random process on the vehicle working condition corresponding to the determination result to serve as the working condition prediction of the next time period. The vehicle working condition prediction method is high in vehicle working condition prediction accuracy rate, does not need to introduce a large number of high-precision sensors, reduces the prediction cost, can carry out the quantitative analysis of the predicted working condition, determines the congestion degree, provides a reliable basis for the urban comprehensive management, and further provides more dimensions for the vehicle driver to select a road.

    本发明涉及一种基于Wiener随机过程车辆工况预测方法和系统,包括以下步骤:1)基于实际采集到的车辆工况数据聚类出不同交通拥堵情况的车辆工况;2)将不同交通拥堵情况的平均工况作为对应交通拥堵情况的代表工况,并根据代表工况判断当前时间段内的车辆拥堵情况的类别;3)基于车辆拥堵情况的判断结果,在判断结果对应的车辆工况上叠加一个Wiener随机过程,作为下一时间段的工况预测。本发明对于车辆工况预测准确度高,无需引入大量高精传感器,降低了预测成本,并可以对预测工况进行定量的分析,确定拥堵程度,为城市综合管理提供可靠依据,也为车辆驾驶员进行道路选择提供了更多维度。
