Disclosed is a destination input device for use in a vehicle navigation system that determines a drive route from a current position to a destination. The device includes a CD-ROM disc storing a plurality of destinations which are categorized into several groups. The user inputs his or her own behavioral schedule or purpose of travel today through a microphone or a touch panel on a display. The display is controlled by a CPU to provide a group selection menu representing a predetermined combination of the groups, in accordance with the inputted user's behavioral schedule. The user selects a specific one of the groups appearing on the displayed group selection menu, so that the display is controlled to provide a destination input menu representing a plurality of destinations included in the selected group, so that the user may readily select and input a desired destination from among those appearing on the displayed destination input menu.

Destination input device in vehicle navigation system

An interactive navigation system includes a navigation processing unit, a current position sensor, a speaker, a microphone and a display. When it is preliminary inferred, based on receipt of a detection signal from the sensor, that a vehicle has probably been diverted from a drive route determined by the navigation processing unit, a machine voice question is produced through the speaker for confirmation of the inferred probability of diversion. A driver or user in the vehicle answers the question, which is input through the microphone and analyzed to be affirmative or negative, from which a final decision is made as to the vehicle diversion. In a preferred embodiment the question is spoken by a personified agent who appears on the display. The agent's activities are controlled by an agent processing unit. Communication between the agent and the user improves reliability and accuracy of inference of any vehicle condition which could not be determined perfectly by a sensor only.

Interactive vehicle control system

A device is mounted in a vehicle which allows one or more of personified agent or imaginary living body to appear before a driver or passengers in the vehicle for communication therewith. A current status sensor (,) detects predetermined vehicle current status data, and a memory (,) stores study data in response to entry of the latest current status data. One of a plurality of communication programs stored in a program table (,) may be selected in accordance with the current status data and/or the study data. An agent control unit (,) controls activity of the agent in accordance with the selected communication program. The determined agent activity is outputted through a display (,) and a speaker (,) for communication with the driver.
