    摘要： In a center apparatus, a feature space projection processing unit performs a feature space projection process for probe data corresponding to a road section which are stored in a current probe data storage unit to extract the feature data, and a change point detecting unit; an event section partitioning unit and an event assigning unit determine a road section corresponding to the feature data, and assign the event information to the determined road section; and an event information distributing unit distributes the event information assigned to the road section. In a vehicle-installed terminal apparatus, a probe data partitioning unit and an orthogonal component decomposition unit performs processes of partitioning and orthogonal component decomposition of the probe data using a feature score vector obtained from the center apparatus, to thereby reduce the probe data to be uplinked.

    摘要： A traffic situation is predicted based on the correlation in the traffic situation between road sections. A base vector generation unit generates the base vectors constituting a feature space representing the correlation between a plurality of links by making a principal component analysis for the necessary time in the past recorded in a necessary time database. A projection point trajectory generation unit records a projection point trajectory of projecting the necessary time in the past recorded in the necessary time database to the feature space in a projection point database. A feature space projection unit projects the necessary time at present to the feature space, and a neighboring projection point retrieval unit retrieves a past projection point in the neighborhood of the concerned projection point from the projection point database, and a projection point trajectory trace unit traces the trajectory of past projection points starting from the retrieved neighboring projection point for a prediction target time width, and an inverse projection unit inversely projects the end point of the concerned trajectory to calculate the predicted value of the necessary time.

    摘要： The invention relates to a method and a control system for controlling an auxiliary device of a vehicle, wherein the auxiliary device is automatically started at a starting time which is determined based on an estimated departure time of the vehicle. In particular, the invention relates to an air-conditioning device which is automatically started for pre-air-conditioning (PAC) based on an estimate departure time of an electric or hybrid vehicle. The invention enables a precise and flexible automatic determination of an activation time of the auxiliary device, wherein determining a time of usage of at least one home appliance of a user of the vehicle; determining a departure time of the vehicle based on the time of usage of the at least one home appliance; and determining a starting time of said auxiliary device based on the determined departure time of the vehicle are determined.
