摘要： In a communication type navigation system that downloads maps, the present invention provides a map data transmission method that can reduce time before guiding is started. A map provision server searches for a traveling route connecting a starting place corresponding to current position information received from an on-vehicle terminal and a destination corresponding to destination information. The server generates guidance information for guiding the vehicle along the searched traveling route and generates a route vicinity map along the traveling route. The server generates traveling route information comprising the searched traveling route and the guidance information, and plural map information blocks into which the route vicinity map containing map information is divided along the traveling route, assigns transmission priority levels to the map information blocks, and transmits the map information blocks according to the transmission priority levels after transmitting the traveling route information.

摘要： In the case of collecting samples, it is difficult to select a representative point of a target area. Thus, the samples are collected from certain positions, resulting in generation of variations of data. The target area is specified on an image to extract features from the target area. Further, clustering is performed for the features on a feature space to obtain representative features, and the obtained representative features are extracted as sampling points.

摘要： A map display method whereby the contents of a road map displayed can be easily and clearly grasped regardless of the running conditions of a vehicle.In a summarized map displayed on a display screen 10, an area including a vehicle position 11, a destination 13 and a guide route 12 between them is displayed in simplified fashion. At a position far from the destination, as shown in FIG. 2A, a summarized map of a wide area is displayed and objects including a road 14 and a facility 15 are limited to a greater degree. With the approach of the vehicle position 11 to the destination 13, as shown in FIG. 2B, the contraction scale is decreased and a summarized map of a middle area is displayed, while at the same time increasing the objects displayed. With a further approach of the vehicle position 11 to the destination 13, as shown in FIG. 2C, a narrower area is displayed in summarization, while at the same time displaying substantially all the objects, thereby making it possible to grasp the neighborhood of the destination 13 in detail.

摘要： According to the present invention, the highly accurate control can be realized in a system for performing the driving control of a vehicle using map data. A car information system 10 for controlling a driving control unit group 50 is located in a vehicle so that the driving control of the vehicle is performed. The car information system includes, a map DB 100 for storing map data, a support area management table 110 in which each kind of attribute data of the map data is associated with information for identifying a field-researched area (support area), and a control unit 200 for estimating an area through which the vehicle travels. The control unit uses a support area management table 110 to judge whether or not attribute data included in the estimated area is associated with the support area. If it is judged that the attribute data is associated with the support area, the control unit performs the driving control of the vehicle by use of the map data, whereas if it is judged that the attribute data is not associated with the support area, not performing the driving control of the vehicle by use of the map data.
