Navigation systems
First Claim
1. A navigation system for a vehicle, comprising:
- a memory that stores map data including a 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 a passing lane, a climbing lane, or a lane for slower traffic based on the detected current vehicle position and the map data; and
if the vehicle is within the predetermined distance, provides guidance regarding the passing lane, the climbing lane, or the lane for slower traffic based on a distance to another vehicle detected by a distance detector mounted on the vehicle.

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.
