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 the 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 processor is configured to generate a lane departure signal based on a combination of the vehicle position, the preceding road structure, the yaw signal, the roll signal, the longitudinal acceleration signal and the lateral acceleration signal.
