  • Patent number: 7280915
    Abstract: A CPU of a navigation device includes a clock unit, a continuous driving time measurement unit that measures continuous driving time from a traveling start time, a course stage prediction unit, and a presenting information controller. The course stage prediction unit selects based on the traveling start time, a first transition determination reference time for transition from a “first stage” to a “middle stage” from prepared data of the first transition determination reference time and a second transition determination reference time for transition from the “middle stage” to a “last stage” from prepared data of the second transition determination reference time. The course stage prediction unit then predicts a course stage by comparing the continuous driving time with the selected transition determination reference times. Depending on the predicted course stage, the presenting information controller presents information convenient for a driver in the predicted course stage.

  • Patent number: 7088266
    Abstract: A map image display device is configured and arranged to improve operability by enabling a map image of a location distant from a currently displayed map image to be appropriately displayed with a simple operation. The map image display device displays names that are subject to a user's input command superimposed on a map image, and, if one of the displayed names is specified, switches the map image to be displayed to a map image in the vicinity of the specified name. At this time, the map image display device selects as the name to be superimposed on the map image at least one distant map name that is not included in the map image to be displayed, and displays that selected distant map name superimposed in the map image peripheral part corresponding to the bearing from the center of the map image to be displayed.

  • Patent number: 7047198
    Abstract: An audio input device calculates respective degrees of coincidence between a user's vocalizations and recognition terms in a voice dictionary by speech recognition and extracts a recognition term having the highest degree of coincidence from the voice dictionary. Further, the audio input device outputs a command to operate one of installations, such as radio, CD player, air conditioner, etc. The audio input device includes a remote controller for transmitting signal waves to the installations equipped with receivers to carry out remote control of the installations. In operation, the larger the installation which the remote controller is directed to has a receiving intensity of the signal wave detected byte receiver, the larger the audio input device makes an extraction weight of the recognition terms concerned with the installation, in the voice dictionary.

  • Patent number: 6581005
    Abstract: A vehicle position calculation apparatus and method are provided to correct a vehicle position to be located on a map route. The vehicle position calculation apparatus has a vehicle position measuring section measuring a vehicle position, a road data supply section supplying road geometrical data including a line segment and a closed region correlated with a road on a map, and a vehicle position correcting section correcting the vehicle position on the map by using the road geometrical data. The position correcting section locates the vehicle position by itself on the map as a corrected vehicle position, in response to a relatively positional relation between the vehicle position and the road geometrical data. In such a correction, the vehicle position correcting section can correct the vehicle position to be in alignment with a point on corresponding one of position correction shapes, or it can correct the vehicle position onto a traveling link generated in response to the road geometrical data.
