This technology relates to a condensation reduction system for a sensor. The system may comprise a sensor cover, wherein the sensor cover is configured to house one or more sensor components, a flexible, external chamber, and a conduit. The external chamber may be communicably coupled to an interior of the sensor cover via the conduit configured such that during an increase of pressure of gas within the sensor cover the gas flows to the external chamber via the conduit and during a decrease in the pressure of gas within the sensor cover the gas flows from the external chamber to the sensor cover via the conduit.

A method and apparatus of adaptive climate control in a vehicle heating, ventilation, air conditioning (HVAC) system includes setting an initial climate condition for one or more zones in a vehicle passenger compartment based upon an occupant of the one or more zones. One or more inputs are monitored, and the climate conditions are changed for at least one of the one or more zones based upon the received one or more inputs. Data relating to the applied changed climate conditions for that occupant is stored.

An apparatus for cleaning air may include conditioning equipment; an input unit which receives an air cleaning command operating the conditioning equipment; and a controller which executes an air cleaning control regardless of a turn on/off of the conditioning equipment according to the air cleaning command to operate the conditioning equipment.

A moisture detection and regulation system is disclosed for a vehicle interior component having a section of material with a moisture absorbent material structure. The system includes a sensing device configured to detect a level of moisture in the section of material. The system also includes a moisture removal element configured to dissipate moisture from the section of material. The system additionally includes an electronic controller fixed to the vehicle structure and in operative communication with each of the sensing device and the moisture removal element. The controller is configured to receive a signal from the sensing device indicative of the detected level of moisture in the section of material and activate the moisture removal element when the detected level of moisture is equal to or greater than a predetermined threshold level of moisture. A vehicle having such a moisture detection and regulation system is also disclosed.

A vehicle defogging and demisting system includes an air handling system, a first humidity sensor adjacent a second row vehicle window, a second humidity sensor adjacent a third row vehicle window and a controller. The controller is configured to defog and demist the second row window in response to a first data stream received from the first humidity sensor and the third row vehicle window in response to a second data stream received from the second humidity sensor. A method of defogging and demisting second and third row vehicle windows of a motor vehicle is also provided.

A method includes: predicting, by a computer device, a time a user will start driving a vehicle; determining, by the computer device, freezing conditions; determining, by the computer device, a time to start a deicing system of the vehicle based on the predicted time and the determined freezing conditions; and generating, by the computer device, an output to start the deicing system at the determined time. A system includes: a windshield wiper that is selectively driven by a windshield wiper motor; a wiper sensor configured to detect an amount of deflection of the windshield wiper from a baseline position; and a computer operatively connected to the windshield wiper motor and the wiper sensor, the computer being configured to: actuate the windshield wiper motor; receive data from the wiper sensor while the windshield wiper motor is actuated; and determine a thickness of ice on a windshield based on the received data.

Systems and methods are provided for implementing a heating, ventilation, and air conditioning (HVAC) system, and processing circuitry configured to determine to enter a drying mode, retrieve a parameter of the HVAC system for the drying mode, and cause the HVAC system to activate the drying mode to direct thermal energy to a particular portion of the vehicle based on the retrieved parameter.

A system and method of selecting air intake between 100% fresh air mode and 100% recirculated air mode for optimum heating/cooling performance, fuel economy and/or high voltage (HV) battery power consumption is disclosed. The system and method includes a partial recirculation control strategy in which the air inlet door is moved progressively to any position by taking into account cooling/heating loads and cabin fogging probability. As cooling/heating loads increase the air inlet door moves toward 100% recirculation mode. As fogging probability increases the air inlet door moves toward 100% fresh air mode. By selectively choosing a position between 100% recirculation and 100% fresh air, fuel economy and/or HV battery power consumption is optimized without compromising passenger comfort or causing fogging on interior glass surfaces. In cooling applications the compressor load is minimized and air conditioning performance is improved due to the reduced evaporator cooling load. The direct result of this improvement is increased fuel economy in the case of the internal combustion vehicle, reduced engine on time in the case of the hybrid electric vehicle (due to reduced HV battery power consumption), and reduced HV battery power consumption in the case of the hybrid electric vehicle (HEV) and the electric vehicle (EV). In heating applications, as the heating load is reduced the fuel economy of the internal combustion (IC) engine will be improved, the engine on time is reduced in the case of the HEV, and HV battery power consumption is reduced in the case of the EV.

A method for controlling air conditioning devices in a transportation vehicle wherein, upon the recording of an operator's air conditioning need and a conversion of the need into an air conditioning function for an air conditioning device, the implementability of the air conditioning need is compared with an influencing variable measured by a sensor. In response to the air conditioning need being recognized as implementable, information asserting this fact is issued to the operator. An apparatus for performing the method.
