PROBLEM TO BE SOLVED: To provide more useful information when the information is applied to a drive assist control.SOLUTION: A drive scene discretization means (4) generates a drive scene sequence by segmenting a sequence of drive behavior data relating to vehicle drive behaviors into discrete drive scenes. Action description generation means (5, 6) extracts feature regions that are regions characteristic of the drive scene sequence, and generates action description on which driver's driving actions in drive scenes relating to the respective feature regions. Event description generation means (7, 8) detects traffic events that possibly influence the driver's driving actions from environmental data representing a vehicle drive environment, and generates event description representing the traffic events to correspond to the drive scene sequence. Context description generation means (9) generates context description representing a relation between the action description and the event description for the traffic event detected at latest timing for the feature regions for which the action description is generated. |
