Abstract:
A vehicle-mounted navigation system which detects a current position of a vehicle, searches for a route to a set destination, and guides the vehicle along the thus-retrieved route, the system comprising:an input device which enables a user to enter commands; a detour request receiving device connected to said input device, wherein said detour request receiving device receives a detour request entered from the input device by the user; a final-point-of-detour receiving device connected to the detour request receiving device, wherein said final-point-of-detour receiving device receives a final point of a segment around which the user requests to make a detour and sets the final point as a final point of detour, after having received the detour request; an alternative path search device connected to said final-point-of-detour receiving device, wherein said alternative path search device searches for an alternative path interconnecting the current position of the vehicle to the final point of detour, after having received the final point of detour; and a detour link device which interconnects the final point of the detour to the destination, or to an original route.
