Abstract: A self-cleaning lens system disposed adjacent a camera is disposed. The system may incorporate a piezoelectric (PZT) lens system having a first PZT element secured to a first peripheral portion of the lens element, which may be responsive to an alternating current (AC) signal applied to the first PZT element. An AC signal may excite the first PZT element to cause shear displacements in opposite longitudinal directions and to create an oscillating shear motion for the first PZT element. The oscillating shear motion may cause an oscillating rotational movement of the lens element that removes the environmental element from a surface of the lens element.

Abstract: A forward facing camera module is configured to, based on an image including a predetermined field of view (FOV) in front of the vehicle: determine a first distance between the vehicle and a first cyclist. A blind zone radar sensor module is configured to: determine a second distance between the vehicle and a second cyclist within a predetermined area on a side of the vehicle based on radar signals transmitted within the predetermined area. A first and second distance modules are configured to generate first and second signals when the first and second distances are decreasing, respectively. An output control module is configured to, when at least one of the first signal and the second signal is generated while a turn light for the side of the vehicle is activated, selectively generate at least one of an audible output and a visual output within a passenger compartment of the vehicle.
