Abstract
Systems and methods are provided for detecting the departure of a vehicle from a set of land boundaries. A boundary determination component is configured to determine an associated set of lane boundaries for a vehicle. A kinematic sensor is configured to measure at least one kinematic parameter associated with the vehicle. A lane departure warning system is configured to determine if the vehicle is crossing one of the determined set of lane boundaries from the at least one kinematic parameter and provide a response signal if the vehicle is crossing one of the determined set of lane boundaries.
Claims20
A system comprising:
- a boundary determination component configured to determine an associated set of lane boundaries for a vehicle;
- a kinematic sensor configured to measure at least one kinematic parameter associated with the vehicle;
- and
- a lane departure warning system configured to determine if the vehicle is crossing one of the determined set of lane boundaries from the at least one kinematic parameter and provide a response signal if the vehicle is crossing one of the determined set of lane boundaries.
A method for detecting the departure of a vehicle from a set of lane boundaries comprising:
- evaluating an image of a region forward of the vehicle to determine if the vehicle appears to be crossing a lane boundary within the image;
- evaluating data from a kinematic sensor to determine if the vehicle is encountering road features associated with a road boundary;
- determining if the vehicle is departing from the set of lane boundaries according to the determination if the vehicle appears to be crossing the lane boundary within the image and the determination if the vehicle is encountering road features associated with the road boundary;
- and
- providing a response signal when said determination step indicates a lane boundary departure.
A vehicle safety system, comprising:
- a forward looking camera configured to image a region of the road forward of the vehicle;
- an image analysis component configured to identify lane markings within images provided by the forward looking camera;
- a kinematic analysis system configured to provide a determination if data from at least one associated accelerometer is consistent with a road feature representing a lane boundary;
- and
- a lane departure warning system configured to determine if the vehicle is exiting its current lane according to the identified lane markings and the determination provided at the kinematic analysis system and providing a response signal if the vehicle is exiting its current lane.
