Sun load on a cabin of a vehicle is determined without a sun load sensor by affixing a relative humidity/temperature sensor to an inside of a windshield of the vehicle. The relative humidity/temperature sensor includes a relative humidity sensor that senses relative humidity of air at the relative humidity sensor, a temperature sensor that senses temperature of the air at the relative humidity sensor and a glass temperature sensor that senses temperature of glass of the windshield. A controller determines the sun load based on readings from the relative humidity/temperature sensor of relative humidity of the air at the relative humidity sensor, temperature of the air at the relative humidity sensor and temperature of the glass of the windshield.

An air condition and lamp control system based on a light sensing of a vehicle may include an illumination sensor configured to detect an amount of irradiation of light irradiated into an interior side of the vehicle to be distinguished in a left and a right, an air condition controller configured to receive a left input voltage and a right input voltage according to the amount of irradiation of light detected by the illumination sensor and to independently compensate for left and right interior temperatures, a voltage amplifier configured to sum the left input voltage and the right input voltage which are transferred from the illumination sensor and to amplify the summed voltage to an amplified voltage, and a lamp controller configured to receive the amplified voltage amplified by the voltage amplifier, to compare the amplified voltage and a prestored lamp operation voltage, and to drive a lamp apparatus.

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.

A vehicle air conditioning apparatus is provided that can prevent temperature variations of the air after the heat exchange in a radiator to reliably control the temperature of the air supplied to the vehicle interior. During the heating operation and the heating and dehumidifying operation, target degree of supercooling SCt when target air-blowing temperature TAO is a predetermined temperature or higher is set to SCt1 that is greater than SCt2 when the target air-blowing temperature TAO is lower than the predetermined temperature. When amount of air Ga supplied from indoor fan 12 is lower than a predetermined value, the target degree of supercooling SCt is corrected, which is set such that the degree of supercooling is lower than target degree of supercooling corrected when the amount of air Ga supplied from the indoor fan 12 is a predetermined value or higher.

An exterior vehicle heating system for melting snow and ice is provided. The exterior vehicle heating system comprises a vehicle having a plurality of wheels with each wheel having a tire, each wheel mounted within a wheel well, and each wheel well having a front side and a rear side. A heat pump is mounted within the vehicle with the heat pump generating heated air. A solar system is mounted to the vehicle with the solar system powering the heat pump. A series of tubing extends from the heat pump to an area adjacent the wheel wells, the wheels, and the tires. Upon activation of the heat pump, the heated air travels from the heat pump to the area adjacent the wheel wells, the wheels, and the tires.

Content capture and distribution systems and techniques are described. In an example, radio frequency signals that carry content are captured by one or more antennas of a content capture system. The content is converted from radio frequency signals the carry the content into an internet protocol format by the content capture system. The converted content is transmitted by the content capture system via a network transfer protocol (e.g., HTTP) for receipt by a content distribution system via a network. The converted content is configured by the content distribution system for streaming via a network streaming protocol. The content is then streamed by the content distribution system via the network using the network streaming protocol for receipt and rendering by at least one client device.

An air conditioning system for motor vehicles includes an air conditioner case having a left path, a right path and a rear seat path. A temperature door is configured to adjust a volume of a cold air or a hot air. A main blower is configured to blow the cold air or the hot air and an air volume distribution door is configured to control opening degrees of the left path and the right path. A rear seat auxiliary blower is configured to increase a volume and a pressure of the cold air or the hot air flowing through the rear seat path. A control unit is configured to, when an air volume distribution ratio of the main blower is changed, correct an opening position of the air volume distribution door and compensate a change in an air volume distribution ratio of the left path and the right path.

An air conditioner for a vehicle includes: a compressor that compresses refrigerant for conditioning air in a vehicle cabin and defines a refrigeration cycle; a detecting section that detects a thermal load of air-conditioning in the vehicle cabin; and a control section that controls a rotational speed of the compressor such that the thermal load detected by the detecting section satisfies a predetermined air conditioning request in the vehicle cabin. In case where the air conditioning request is satisfied by controlling the rotational speed of the compressor, the control section periodically switches between a reference rotational speed and a low rotational speed that is lower than the reference rotational speed in order to maintain a state where the air conditioning request is satisfied. The reference rotational speed is a rotational speed within a predetermined range that includes the rotational speed at which the air conditioning request is satisfied.
