Abstract

An in-vehicle system for determining whether a vehicle has moved off of a main roadway and into an exit lane. A navigation unit determines that an exit is approaching on a first side of the vehicle, and a camera obtains image data regarding lane markings and exit signs in response to a notification that the exit is approaching. An image processor identifies predetermined patterns among the lane markings, including V-shaped patterns or Y-shaped patterns. The system determines that the vehicle has moved into the exit lane in response to an identification of one of the predetermined patterns on a second side of the vehicle opposite the first side of the vehicle. The system may verify its determination based on recognition of an exit sign on the second side of the vehicle.
