Abstract:
1. A system for detecting departure of a vehicle from a lane on a road, the system comprising: a processor; an imaging sensor in electrical communication with the processor, the imaging sensor generating a vehicle position signal corresponding to the vehicle position relative to the lane and a preceding lane structure corresponding to a direction of the lane in front of the vehicle; an inertial sensor assembly in electrical communication with the processor, the inertial sensor assembly generating a yaw signal and roll signal corresponding to a yaw angle and roll angle of the vehicle, the inertial sensor assembly generating a lateral acceleration signal corresponding to a lateral acceleration of the vehicle; wherein the lateral acceleration signal, the yaw signal and the roll signal from the inertial sensor assembly are used in conjunction with preceding lane structure information from the imaging sensor to predict departure from the lane.
