Abstract

A system for mitigating driver distraction and/or drowsiness for a vehicle having a steering wheel and windshield comprises an arm that is adapted for attachment to the vehicle so that the arm is juxtaposed an exterior surface of the windshield and so that it sweeps a portion of the exterior surface of the windshield in front of the steering wheel to provide a motion signal. The system includes a driver distraction and/or drowsiness monitor and a control device responsive to the driver monitor, for operating the arm. The arm preferably is part of a windshield wiper assembly and preferably includes a visual signal and/or an auditory signal. A method for refocusing the attention of a distracted driver uses elements of the system.

Claims

1. A system for mitigating driver distraction and/or drowsiness for a vehicle having steering wheel and a windshield, the system comprising:

a wiper arm attached to the vehicle and adapted to sweep a portion of an exterior surface of the windshield in front of the steering wheel;

means for operating the wiper arm to sweep the exterior surface of the windshield;

one or more electrically activated light emitting devices attached to the wiper arm and visible to a driver seated behind the steering wheel for providing a visual signal when activated that is visible to the driver seated behind the steering wheel to capture the driver'"'"'s attention;

a control device for actuating said means to operate the wiper and for activating the light emitting devices; and

a driver distraction and/or drowsiness monitor for detecting a distracted or drowsy condition of a driver and providing a signal in response to detection of a distracted or drowsy condition of said driver to activate said control device to cause said control device to actuate said means for operating the wiper arm and to activate said light emitting devices for providing said visual signal.

2. The system for mitigating driver distraction and/or drowsiness of claim 1 wherein the wiper arm contacts the windshield so as to produce an auditory signal to supplement the motion signal of the arm and the visual signal of said light emitting devices.

3. The system for mitigating driver distraction and/or drowsiness of claim 2 wherein the wiper arm is part of a windshield wiper assembly.

4. The system for mitigating driver distraction and/or drowsiness of claim 3 wherein said light emitting devices are LEDs.

5. The system for mitigating driver distraction and/or drowsiness of claim 4 wherein the LEDs are attached near a free end of the arm of the windshield wiper assembly.

6. The system for mitigating driver distraction and/or drowsiness of claim 4 wherein the LEDs are attached to a wiper blade sub-assembly of the windshield wiper assembly.

7. A method for mitigating distraction and/or drowsiness of a driver of a vehicle, said vehicle comprising a windshield and a steering wheel, said method comprising:

providing a wiper arm operable by a control device to sweep a portion of an exterior surface of the windshield in front of the steering wheel;

providing one or more electrically operated light emitting devices attached to the wiper arm so as to be visible to a driver seated behing the steering wheel and operable by the control device, said light emitting devices being effective when operated to provide a visual signal that is visible to the driver seated behind the steering wheel to capture the driver'"'"'s attention;

monitoring the driver to detect a distracted or drowsy condition, said monitoring being pefformed by a driver distraction and/or drowsiness monitor producing a signal in response to detection of a distracted or drowsy condition of said driver; and

supplying said signal to said control device to cause said control device to actuate said wiper and to operate said light emitting devices in response to said signal.

8. The method of claim 7 wherein said light emitting devices are operated intermittenly.

9. The method of claim 8 wherein said light emitting devices are LEDs.
