An operation determination processing section of a center extracts words included in the utterance of a driver and an operator, reads an attribute associated with each word from a synonym and related word in which an attribute is stored so as to be associated with each word, reads a domain of a candidate or the like for the task associated with the attribute from the synonym and related word in which domains of a candidate for a task associated with the read attribute or domains of a task to be actually performed are stored, totals the domains read for each word for words included in the utterance of the driver or the like, and estimates those related to a domain with a highest total score as the candidate for the task and the task to be actually performed. In this manner, it is possible to estimate the task with high accuracy.

Operating system and method of operating

A vehicle information processing unitcollects vehicle information, which is information relating to the discharge amount of exhaust gas of at least one at any of a predetermined point, a predetermined section, and a predetermined period of time. An ecological traveling history DBaccumulates the vehicle information collected by the vehicle information processing unitfor each point through which the vehicle has traveled. A display devicedisplays the vehicle information accumulated in the ecological traveling history DBby an image on a map including each point for each point through which the vehicle has traveled. Therefore, it becomes possible to allow a driver to recognize previous traveling performance at the point through which the vehicle has traveled, and to more effectively provide the driver with a guide or a motivation to perform ecological traveling, thereby providing a more useful in-vehicle apparatus which allows the driver to perform ecological traveling.

In-vehicle apparatus and information processing center

A navigation devicehaving a function to modify a route comprises an operational object detecting partconfigured to detect a point or a section on the route as an operational object, a fixed point setting partconfigured to set as fixed points two points on the route sandwiching the operational object therebetween, an operational object displacement detecting partconfigured to detect a displacement of the operational object, a path changing partconfigured to change a path of the route depending on the displacement of the operational object while elongating or contracting a line connecting the operational object and the fixed point, and a route re-searching partconfigured to re-search and display an alternate route continuously depending on the changing path.
