Intercommunication system for vehicle
First Claim
1. An intercommunication system for a vehicle, comprising:
- map information outputting means for outputting a map of a road on which a subject vehicle travels;
navigating means for outputting a traveling direction and a current position of the subject vehicle on the map;
judging means for judging on the basis of outputs from said map information outputting means and said navigating means whether a vehicle speed of the subject vehicle is suitable for passing a shape of a road ahead of the subject vehicle;
communication means for transmitting a traveling condition of the subject vehicle to another vehicle when said judging means judges that the vehicle speed of the subject vehicle is unsuitable based on an output from said judging means and for receiving a traveling condition of the another vehicle transmitted from the another vehicle; and
alarm means for giving an alarm to a driver of the vehicle based on the received traveling condition of the another vehicle.

Abstract
An intercommunication system for a vehicle is disclosed including a judging mechanism for detecting whether a corner exists ahead of a subject vehicle in a traveling direction on a road based on outputs from a navigating mechanism and a map information outputting mechanism in a navigation system. It is judged whether the vehicle speed of the subject vehicle is excessive or an overspeed for safely passing through a detected corner. If the vehicle speed of the subject vehicle is an overspeed, the speed of the vehicle is reduced through an automatic vehicle speed control mechanism and/or an alarm means which alerts the vehicle driver of the overspeed condition. A mechanism is also provided for detecting whether another vehicle is traveling through or approaching a detected corner. If another vehicle is detected, when the subject vehicle reaches a position which is a predetermined distance short of the corner, intercommunication between the subject vehicle and the other vehicle passing through the corner is initiated pertaining to the vehicle speed, the traveling direction and the like through the communication means, so that the subject vehicle can safely and reliably pass by the other vehicle.

-
map information outputting means for outputting a map of a road on which a subject vehicle travels; navigating means for outputting a traveling direction and a current position of the subject vehicle on the map; judging means for judging on the basis of outputs from said map information outputting means and said navigating means whether a vehicle speed of the subject vehicle is legal for passing a section of a road ahead of the subject vehicle; communication means for transmitting a traveling condition of the subject vehicle to another vehicle when said judging means judges that the vehicle speed of the subject vehicle is illegal based on an output from said judging means and for receiving a traveling condition of the another vehicle transmitted from the another vehicle; and alarm means for giving an alarm to a driver of the subject vehicle based on the received traveling condition of the another vehicle. - View Dependent Claims (16, 17, 18, 19, 20)
