DRIVING CONTEXT GENERATION SYSTEM

摘要

In a system, a behavior description generator extracts a feature portion from at least one of segmented behavior-data sequences corresponding to at least one target driving situation included in sequential driving situations, and generates behavior-description information indicative of a description of a driver's behavior associated with the at least one target driving situation. An event description generator sequentially detects traffic events in at least one environmental data sequence indicative of time-series driving environments of a vehicle. The event description generator generates event-description information including a description indicative of each of the detected traffic events. A context description generator extracts, from the sequentially detected traffic events, one target traffic event that is detected immediately adjacent to the feature portion. The context description generator generates context information indicative of a context between behavior-description information and the event-description information about the target traffic event.

1. A driving context generation system comprising:
a discretizer configured to discretize at least one driving behavioral data sequence representing time-series driving behaviors of a vehicle into segmented behavior-data sequences, each of the segmented behavior-data sequences corresponding to one of sequential driving situations of the vehicle; a behavior description generator configured to: extract a feature portion from at least one of the segmented behavior-data sequences corresponding to at least one target driving situation included in the sequential driving situations; and generate behavior-description information indicative of a description of a driver's behavior associated with the at least one target driving situation; an event description generator configured to: sequentially detect traffic events in at least one environmental data sequence indicative of time-series driving environments of the vehicle, each of the detected traffic events having a potential to impact on driver's driving behaviors of the vehicle; and generate event-description information including a description indicative of each of the detected traffic events; and a context description generator configured to: extract, from the sequentially detected traffic events, one target traffic event that is detected immediately adjacent to the feature portion; and generate context information indicative of a context between the behavior-description information generated by the behavior description generator and the event-description information about the target traffic event generated by the event description generator.
