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.

A sensor cleaning system for a vehicle is disclosed. In particular, the sensor cleaning system has anti-freezing and defrosting functions. The sensor cleaning system includes: an air tank configured to store compressed air; a heating element disposed in the air tank and configured to apply heat to the air tank; and a controller configured to operate the heating element when a preset condition is satisfied.

A sensor cleaning system has anti-freezing and thawing functions in an air-jet sensor cleaning system. The sensor cleaning system includes a distributor having a channel into which compressed air is introduced and having a plurality of exits. The distributor is configured to distribute the compressed air from the channel to each of the exits. A valve of the system is formed integrally with the distributor and is capable of being opened or closed to allow or prevent supply of the compressed air through each of the exits. A heating element of the system is configured to apply heat to the distributor and a controller is configured to operate the heating element when a preset condition is satisfied.

A method of controlling a HVAC system of a vehicle includes repeatedly sensing an area of a window of the vehicle that is not covered by frost with a sensor positioned adjacent the window. When the sensed area not covered by frost is less than an area threshold value, a HVAC controller controls the HVAC system to operate in a defrost mode. When the sensed area not covered by frost is equal to or greater than the area threshold value the HVAC controller controls the HVAC system to operate in a cabin heating mode. The HVAC controller automatically switches the HVAC system from the defrost mode to the cabin heating mode when the sensed area not covered by frost increases to a value that is equal to or greater than the area threshold value.

An air intake of an air conditioning system a motor vehicle having a fresh air duct configured to receive fresh air, a recirculated air duct configured to receive air from a passenger area of the motor vehicle, and an air outlet configured to channel the fresh air or the air from a passenger area of the motor vehicle to a blower. The air intake also has a valve disposed in the housing and rotates about a rotational axis between a first position and a second position.

A device for cleaning an optical lens of a parking assistance camera includes at least one inner annular body and at least one outer annular body. The at least one outer annular body is configured such that the fluid chamber is closed with respect to surroundings of the device when the at least one outer annular body is in the resting position. The at least one outer annular body is configured such that the fluid chamber is open with respect to the surroundings of the device such that when said at least one outer annular body is in the cleaning position, a fluid introduced into the fluid chamber exits the fluid chamber in the direction of the optical lens. The at least one fluid supply element opening into the fluid chamber is disposed on the at least one inner annular body.
