DEVICE FOR PROTECTING AN OPTICAL SENSOR, AND ASSOCIATED DRIVER ASSISTANCE SYSTEM AND CLEANING METHOD
First Claim
1. A device for protecting an optical sensor for motor vehicle, the protection device comprising:
- a transparent optical element mounted rotably movable about an axis of rotation, said optical element being configured to be arranged upstream from an optical unit of the optical sensor such that the axis of rotation of said optical element coincides with the optical axis of the optical sensor; and
a motor comprising a rotary shaft configured to rotate about an axis of rotation, the motor being configured to rotate said optical element such that the axis of rotation of said optical element further coincides with the axis of rotation of the rotary shaft of the motor.
