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 travel route evaluation system is provided which is capable of enhancing the driver's consciousness of traveling on the a recommended route, in order to improve a degree of attainment of purposes, such as suppression of a fuel consumption and shortening of a required time, that would be obtained by presenting the recommended route. The system includes: a route setting unit for setting a recommended route from a departure point to a destination, based on traveling environment information associated with a traveling environment of a vehicle and map data, a ratio calculation unit for calculating a recommended route travel ratio which is a proportion of the recommended route in a traveled route on which the vehicle traveled; and an evaluation information acquisition unit for acquiring evaluation information based on the recommended route travel ratio.

Travel route evaluation system and travel route evaluation program

An inattentive state determination device includes an observed amount acquiring means for acquiring information on the driver's line of sight and at least one of either information on driving operations or information on the traveling state as an observed amount; and an inattentive state determining means for determining the inattentive state of the driver based on the stochastic relationship between the inattentive state and the observed amount as well as the observed amount acquired by using the observed amount acquiring means. In addition, the inattentive state determining means calculates the probability that the driver is driving inattentively and determines that the driver is driving inattentively when the calculated probability exceeds a threshold.

Inattentive state determination device and method of determining inattentive state

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 fuel economy driving assistance apparatus includes advice provision means for providing a driver with driving advice that contributes to improvement of fuel economy of a vehicle; driving tendency estimation means for estimating a driving tendency of the driver in each driving situation; and advice mode changing means for changing a mode of the driving advice, according to the driving tendency of the driver estimated by the driving tendency estimation means.

A route searching apparatus includes a travel route accumulation unit, an algorithm selection unit to select route searching algorithms to meet the preference of a user based on the accumulated travel routes, and a route searching unit to perform a route search up to a destination by using the selected algorithms. Preferably, the algorithm searching unit searches for each of the travel routes accumulated in the accumulation unit by means of several algorithms, calculates, for each algorithm, a match rate between the searched route and the actual travel route, and selects an algorithm of the highest match rate. Also, it is preferable that a condition common to roads avoided by the user is extracted from the accumulated travel routes, and a route search is performed by adjusting search costs so as to make such roads less prone to be selected.

A fuel consumption saving drive supporting device which calculates a mileage of each driver and informs each driver of advice based on an increase or a decrease of the calculated mileage is disclosed. The fuel consumption saving drive supporting device extracts a drive operation of the driver or a drive condition of a vehicle of the driver for increasing the mileage, and informs the driver of the advice in the drive operation or the drive condition corresponding to the extracted drive operation or the extracted drive condition.

Fuel consumption saving drive supporting device

The invention provides an information providing device and an information providing system which can provide suitable destination information according to the utilization situation of a user. The information providing device is an information providing device mounted on a vehicle and provides information on potential destinations. An information providing unit which provides information on a potential destination in accordance with the performance of electronic payment at a destination after traveling assistance is provided. By providing this information on a potential destination, a potential destination can be selected on the basis of information on a destination for which traveling assistance has actually been provided and which has been utilized, information on the potential destination can be provided, and information on a suitable potential destination according to the actual utilization situation of a user can be provided.

Apparatus and methods are described for assisting a requestor to identify and reserve a resource that meets the need of the requestor's request. For example, a request can be augmented using augmentation data, such as current position and requestor preferences, and resources are located and ranked according to their match against the augmented request. A person who is the requestor may engage in another attention demanding task, such as driving a car, while resources well matched to preferences are located. Preference data may be determined from social network data, a preference file, and/or other sources.

A driving diagnosis apparatus temporarily records a diagnosis result of the user before changed when a user is switched, and starts to diagnose the user after changed. Accordingly, since driving status of each user is independently diagnosed, the diagnosis result is proper. Further, when a driving distance of the vehicle is smaller than a threshold, the diagnosis result of a driving interval is not recorded so that the driving interval is removed from an object of giving a point. Influence to environment is also considered in evaluation of the driving status. Accordingly, in the driving diagnosis apparatus and a driving diagnosis system for diagnosing driving status and for evaluating a driver based on the diagnosis result, the diagnosis and the evaluation are properly performed.
