Zusammenfassung:A vehicle includes a vehicle frame and an optical device mounted on the vehicle frame. A first temperature sensor senses ambient air temperature surrounding the vehicle frame, a second temperature sensor senses a temperature of a lens of the optical device, and a humidity sensor senses moisture content of air proximal to the lens. An exhaust directs gas at the lens in response to the sensed ambient air temperature, the sensed lens temperature, and the sensed moisture content.
