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.

1. An interactive vehicle control system comprising:a sensor mounted on a vehicle for detecting a specific physical parameter that relates to the vehicle or to driving of the vehicle and for outputting a detection signal; discriminating means for inferring, from said detection signal, with a degree of reliability, existence of at least one specific condition to be considered in vehicle control, said physical parameter relating to said one specific condition; output means for outputting a question for confirmation of said specific condition when the degree of reliability determined by said discriminating means lies within a predetermined range; input means for inputting a user's answer to said outputted question; decision making means for, based on said user's answer, determining whether or not said specific condition actually exists; and execution means for executing a vehicle control operation in accordance with a result of the determination by said decision making means.
