Navigation systems
First Claim
1. A navigation system for a vehicle, comprising:
- a memory that stores map data including starting points for each of the following special purpose lanes;
passing lanes, which are lanes that are specifically designated within the map data as being used for vehicles to pass other slower vehicles;
climbing lanes, which are lanes that are specifically designated within the map data as being used for vehicles to move slowly uphill; and
lanes for slower traffic, which are lanes that are specifically designated within the map data as being used for vehicles to move more slowly than vehicles in adjacent lanes;
a vehicle position detector that detects a current position of the vehicle;
a receiver for receiving traffic congestion information; and
a controller that;
determines whether the vehicle is within a predetermined distance of an approaching one of the stored starting points based on the detected current vehicle position and the map data;
determines whether a link in which the vehicle is currently traveling is congested based on the received traffic congestion information;
if the vehicle is within the predetermined distance of the approaching starting point, provides guidance regarding a passing lane, a climbing lane, or a lane for slower traffic corresponding to the approaching starting point based on a distance to another vehicle detected by a distance detector mounted on the vehicle; and
does not provide the guidance regarding the corresponding passing lane, climbing lane, or lane for slower traffic if it is determined that the link in which the vehicle is currently traveling is congested.

Abstract
Systems, methods, and programs, store map data including a roadway network, detect a current position of the vehicle, and detect or receive at lest one of a distance to another vehicle, a speed of another vehicle, and traffic congestion information. The systems, methods, and programs determine whether the vehicle is within a predetermined distance of a passing lane, a climbing lane, or a lane for slower traffic based on the detected current vehicle position and the map data. If the vehicle is within the predetermined distance, the systems, methods, and programs provide guidance regarding the passing lane, the climbing lane, or the lane for slower traffic based on at least one of the distance to the other vehicle, the speed of the other vehicle, and/or the received traffic congestion information.

12. A navigation system for a vehicle, comprising:
-
a memory that stores map data including starting points for each of the following special purpose lanes; passing lanes, which are lanes that are specifically designated within the map data as being used for vehicles to pass other slower vehicles; climbing lanes, which are lanes that are specifically designated within the map data as being used for vehicles to move slowly uphill; and lanes for slower traffic, which are lanes that are specifically designated within the map data as being used for vehicles to move more slowly than vehicles in adjacent lanes; a vehicle position detector that detects a current position of the vehicle; a receiver for receiving traffic congestion information; and a controller that; determines whether the vehicle is within a predetermined distance of an approaching one of the stored starting points based on the detected current vehicle position and the map data; if the vehicle is within the predetermined distance of the approaching starting point, provides guidance regarding a passing lane, a climbing lane, or a lane for slower traffic corresponding to the approaching starting point based on the received traffic congestion information; and does not provide the guidance regarding the corresponding passing lane, climbing lane, or lane for slower traffic if a link in which the vehicle is currently traveling is congested.

13. A navigation system for a vehicle, comprising:
-
a memory that stores; map data including starting points for each of the following special purpose lanes; climbing lanes, which are lanes that are specifically designated within the map data as being used for vehicles to move slowly uphill; and lanes for slower traffic, which are lanes that are specifically designated within the map data as being used for vehicles to move more slowly than vehicles in adjacent lanes; and average vehicle speeds for links in the roadway network; a vehicle position detector that detects a current position of the vehicle; and a controller that; determines whether the vehicle is within a predetermined distance of an approaching one of the stored starting points based on the detected current vehicle position and the map data; determines a link that the vehicle is currently traveling on based on the detected current vehicle position and the map data; accesses an average vehicle speed for the currently traveled link from the stored average vehicle speeds; accesses a current speed of the vehicle; determines a speed of another vehicle detected by another vehicle speed detector mounted on the vehicle; if the vehicle is within the predetermined distance of the approaching starting point, provides guidance regarding a climbing lane or a lane for slower traffic corresponding to the approaching starting point; and does not provide the guidance regarding the corresponding climbing lane or lane for slower traffic if the accessed current speed of the vehicle is less than the accessed average vehicle speed for the currently traveled link and the speed of the other vehicle is less than the accessed current speed of the vehicle.
