Navigation system
First Claim
1. A navigation device for use with an information center that receives probe information transmitted from the navigation device, the information center configured to store limiting information for specifying a content of the probe information to be transmitted in accordance with predefined factors, specify a predefined factor corresponding to the navigation device, select the limiting information based on the specified predefined factor, and transmit the selected limiting information to the navigation device, the navigation device comprising:
- a receiver that receives the limiting information;
a controller that;
collects probe information; and
selects only the probe information specified by the limiting information for transmission to the information center; and
a transmitter that transmits the selected probe information to the information center.

Abstract
A navigation system includes an information center and a navigation device installed in a probe vehicle. The information center stores limiting information for specifying a content of probe information in accordance with predefined factors, specifies a predefined factor corresponding to a navigation device, selects the limiting information based on the specified predefined factor, transmits the selected limiting information to the navigation device, and receives the corresponding probe information transmitted from a navigation device. The navigation device receives the limiting information from the information center, collects probe information, selects only the probe information specified by the received limiting information for transmission to the information center, and transmits the selected probe information to the information center.
