Interactive vehicle control system

An interactive automatic transmission control system comprising:

• sensor means mounted on a vehicle for inferring, with a degree of reliability, that a vehicle is now running uphill or downhill at an angle of inclination greater than a predetermined angle;
• output means for outputting a question for confirmation of the inference by said sensor means when the degree of reliability lies within a predetermined range;
• input means for inputting a user's answer to said outputted question;
• and
• automatic transmission control means for outputting a down-shift command to an automatic transmission when it is confirmed by said user's answer that the vehicle is actually running uphill or downhill.

An interactive vehicle automatic transmission control system comprising:

• sensor means mounted on a vehicle for inferring, with a degree of reliability that a vehicle is now running on a slippery road;
• output means for outputting a question for confirmation of the inference of existence of the slippery road by said sensor means, when the degree of reliability is within a predetermined range;
• input means for inputting a user's answer to said outputted question;
• and
• an automatic transmission control means for outputting a down-shift command to an automatic transmission when it is confirmed by said user's answer that the vehicle is actually running on the slippery road.

An interactive navigation system comprising:

• a current position sensor for detecting current position of a vehicle;
• route-finding means for determining a drive route from the current position detected by said current position sensor to a predetermined destination;
• inference means, that receives during driving a detection signal from said current position sensor, for inferring from the detection signal, with a degree of reliability, that the vehicle has been diverted from the drive route determined by said route-finding means;
• a speaker that outputs a machine voice question by which said inferred diversion can be confirmed, when the degree of reliability is within a predetermined range;
• a microphone that inputs a user's voice answer to said question;
• final decision making means for, based on said user's voice answer, determining whether or not the vehicle has actually been diverted from the drive route;
• and
• position correct means for correcting vehicle position on a map in accordance with a result of determination by said final decision making means.

An interactive navigation system comprising:

• a current position sensor for detecting current position of a vehicle;
• route-finding means for determining a drive route from the current position detected by said current position sensor to a predetermined destination;
• inference means for inferring, with a degree of reliability, a traffic jam on the drive route which has been determined by said route-finding means and along which the vehicle is currently driven;
• a speaker that outputs a machine voice question by which said inferred traffic jam can be confirmed, when the degree of reliability is within a predetermined range;
• a microphone that inputs a user's voice answer to said question;
• and
• final decision making means for, responsive to said user's voice answer, determining whether or not there is actually a traffic jam on the current drive route;
• wherein said route-finding means determines another drive route to the destination which detours the traffic jam, when said final decision making means confirms the traffic jam on the current drive route.
