SYSTEMS AND METHODS TO DEFOG A VEHICLE GLASS SURFACE

A vehicle including a front windshield, a sensor, a camera, an HVAC unit and a processor is disclosed. The sensor is configured to detect a humidity level at the front windshield, and the camera is configured to capture an image of a target vehicle glass surface. The processor is configured to determine that the humidity level is greater than a predefined threshold based on inputs obtained from the sensor. The processor further obtains the image from the camera responsive to determining that the humidity level is greater than the predefined threshold, and detects a presence of fogging on the target vehicle glass surface based on the image. The processor additionally determines a fogging level on the target vehicle glass surface based on the image, and controls an HVAC unit operation based on the fogging level to defog the target vehicle glass surface
