VEHICULAR COOLING SYSTEM FOR FORWARD CAMERA MODULE

A vehicular vision system includes a camera module mounted at an in-cabin side of a windshield of a vehicle. The camera module includes a temperature sensor. An airflow source of a heating, ventilation and air conditioning (HVAC) system of the vehicle is in fluid communication with a vent at an interior portion of the vehicle. When circuitry of the camera module is electrically operated, and when the vehicular vision system controls the HVAC system to direct airflow via the vent along a portion of the camera module, heat generated by the circuitry of the camera module during operation of the circuitry is dissipated. The vehicular vision system controls the HVAC system to direct airflow via the vent along the portion of the camera module responsive to an output of the temperature sensor being indicative of the circuitry of the camera module operating outside of a set operating temperature range.
