US Patent 11483514 Vehicular vision system with incident recording function

A vehicular vision system includes a camera module having an imaging array and spectral filtering at the imaging array. With the camera module attached at an in-cabin side of a vehicle windshield, the imaging array of the camera module views through the windshield and forward of the equipped vehicle. Image data captured by the imaging array is provided to and processed at an ECU for at least two driving assist systems of the vehicle. The captured image data is temporarily saved in volatile memory. Responsive to occurrence of an emergency event, image data captured by the imaging array of the camera module is saved in non-volatile memory. The captured image data saved in non-volatile memory includes (i) captured image data temporarily saved in volatile memory prior to the occurrence of the emergency event and (ii) image data captured for a period of time after the occurrence of the emergency event.
