Abstract (en)

[origin: US6131064A] A process for automated vehicle-autonomous detection of a particular traffic situation by continuously detecting an instantaneous vehicle speed onboard a vehicle. The detected vehicle speeds are classified using guidelines which may be based on rigid values or on fuzzy logic relationships, into one or more of a plurality of traffic categories by assigning a weight for that detected vehicle speed to each of the traffic categories. Thereafter, for each traffic category the weights associated with the detected speed values are integrated over time to calculate an integrated result for each traffic category. The integrated results of the traffic categories are then evaluated based on predetermined rules or criteria to generate a probabilistically-based traffic detection value indicating the traffic category representing the vehicles' current traffic situation. The traffic categories and guidelines or membership functions or relationships are defined for use with a particular type of road.
