Abstract:
1. A method for monitoring an abnormal state of a vehicle using a clustering technique, comprising: transforming, using a hardware computing device, Control Area Network (CAN) data collected from an Electronic Control Unit (ECU) mounted on the vehicle, into coordinates on a distribution map in a multidimensional space, in accordance with a range of the coordinates on the distribution map; analyzing, using the hardware computing device, the distribution map to thereby determine a number of clusters to be formed, and selecting the determined number of initial center points for forming the clusters; clustering, using the hardware computing device, the coordinates on the distribution map based on the initial center points, to thereby generate the clusters; extracting, using the hardware computing device, at least one piece of data from each of the clusters, and calculating, for each cluster, a state feature using a difference between maximum and minimum values of an attribute of the at least one piece of data; and monitoring, using the hardware computing device, a current state of the vehicle based on current CAN data of the vehicle and the state features of the generated clusters, including
