US Patent 12094132 Vehicular vision system

A vehicular vision system includes a sensor disposed at a vehicle and having a field of sensing exterior of the vehicle. The sensor captures sensor data. Electronic circuitry of an electronic control unit (ECU) includes a processor for processing sensor data captured by the sensor. Responsive to the vehicle being parked, captured sensor data is processed at the ECU to determine a topography of the environment at the parked vehicle. The ECU, responsive to determining the topography at the parked vehicle determines presence of a hazard of the topography. The ECU, responsive to determining presence of the hazard, notifies an occupant of the vehicle of the hazard prior to the occupant exiting the parked vehicle.
