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. |
