Traffic congestion detection apparatus and vehicle control apparatus

摘要

A traffic congestion detection apparatus includes a traveling information acquisition unit for acquiring traveling information relating to a traveling state of a vehicle, and a traveling zone determination unit for determining which one of at least three zones including a central zone of a congestion area the vehicle is traveling in, based on current traveling information acquired by the traveling information acquisition unit.

主权项

1. A vehicle control apparatus, comprising:
a traffic congestion detection apparatus mounted on a vehicle and which comprises:
a traveling information acquisition unit which acquires traveling information relating to a traveling state of the vehicle;a traveling zone determination unit which determines which one of a tail zone, a central zone, and a restoration zone of a congestion area the vehicle is traveling in, based on current traveling information acquired by the traveling information acquisition unit;a traveling information analysis unit which performs multivariate analysis on a plurality of items of travel information acquired by the traveling information acquisition unit, calculating at least two variables at different times based on an average, a standard deviation, kurtosis, skewness, and average speed difference of the vehicle speed obtained at the different times, and determining a region to which the calculated variables belong, as a zone in which the vehicle is traveling, the region is one of plural regions which correspond to the tail zone, the central zone, and the restoration zone; anda driving assist unit which assists driving of the vehicle based on a result of the determination by the traveling zone determination unit, wherein the tail zone is a zone where the vehicle exhibits a tendency to decelerate, and corresponds to a zone where the vehicle has just entered the congestion area, and the central zone is a zone where the vehicle exhibits stable speed variation, and corresponds to a central zone of the congestion area, and the restoration zone is a zone where the vehicle exhibits a tendency to accelerate, and corresponds to a zone where the vehicle is about to get out of the congestion area.
