VEHICLE NAGIVATION SYSTEM
First Claim
1. A computer readable medium encoded with computer executable instructions, the computer executable instructions executable with a processor, the computer readable medium comprising:
- instructions executable to receive position data;
instructions executable to receive navigation information comprising a preselected navigation route generated by a navigation system;
instructions executable to calculate a state value based on the position data and the navigation information;
instructions executable to determine a state value limit based on at least one of a current velocity of a vehicle, a regulatory limit, and a roadway limit; and
instructions executable to output a control signal when the state value fails to exceed the state value limit.

Abstract
A navigation system may include a positioning device for generating a position data signal, a geographical data storage device for generating a digital map data signal, a processing device for generating navigation information based on the position data signal and the digital map data signal, and a turn control device for generating output signals to activate and/or deactivate turn signals of the vehicle and/or to enable an autonomous vehicle control system to perform a driving maneuver. The turn control device may analyze the navigation information to detect when the distance to an approaching turn fails to exceed a predetermined limit or when the turn has been completed or bypassed. The turn control device may analyze the navigation information and a velocity data signal generated by a velocity sensing device to detect when the time to the approaching turn fails to exceed a predetermined limit.
