  • Patent number: 10647176
    Abstract: An air conditioner ECU transmits a communication message in a format for controlling a stepper motor. Since a stepper motor and a DC motor are controlled by a communication message in respective predetermined formats, the DC motor cannot be controlled with the communication message transmitted by the air conditioner ECU. Therefore, the sub ECU relays the communication message transmitted by the air conditioner ECU and drives the actuator. The sub ECU converts the communication message transmitted by the air conditioner ECU into control information corresponding to a predetermined format of each actuator and drives each actuator based on the converted control information.

  • Patent number: 9981525
    Abstract: A heater core is disposed to be inclined with respect to an airflow direction so that a first header tank unit is displaced downstream of a second header tank unit in the airflow direction. Therefore, when a first air mixing door blocks a first heating portion, an air stagnates between a downstream lateral portion of the first heating portion and a second partition wall downstream of the first heating portion, and the air is unlikely to be heated downstream of the first heating portion. Likewise, the air is unlikely to be heated upstream of a second heating portion in a second airflow passage. Therefore, a maximum cooling performance of a vehicle air conditioning unit can be restrained from being deteriorated due to a heat from a heater core.

  • Publication number: 20140305626
    Abstract: A method is provided for determining an air flow in a vehicle air conditioning system that comprises an inlet; a plurality of outlets; at least one air duct for guiding air from the inlet to the outlets, each air duct being characterized by a predetermined flow resistance coefficient; at least one flap characterized by a flow resistance based on a degree of opening of the flap; and a fan for creating an air flow from the inlet to an outlet. The method comprises determining a total equivalent flow resistance between a predetermined location in the system and an interior of the vehicle, wherein flow resistances are treated as resistances in an electric circuit, and a total equivalent flow resistance is determined. Treating a pressure drop as equivalent with a voltage drop, the air flow can be determined, as the pressure is equal to the resistance times the flow squared.

  • Patent number: 8800644
    Abstract: A system and method for environmental management of a vehicle automatically operates a vehicle climate control system to defog a vehicle windshield, while still operating at or near environmental comfort guidelines determined by a vehicle occupant. The method may be executed by an HVAC control system that is configured with a preprogrammed algorithm to operate an HVAC to achieve the desired results. A number of sensors can provide inputs to the control system, which can also receive inputs from a number of manual overrides operable by an occupant of the vehicle. The preprogrammed algorithm is configured to act on the various inputs to operate the HVAC to strike an appropriate balance between occupant comfort and windshield defogging.

  • Publication number: 20140131026
    Abstract: A vehicle air circulating system comprises a controller, an interior condition sensor attached to the controller, an instrument panel, and a deployable register assembly attached to the controller and pivotably attached to the instrument panel. The register assembly includes a first register and a second register and is movable between a closed position in which the first register is recessed within the instrument panel and is thus obstructed and an open position in which the first register is deployed. The second register remains unobstructed whether the register assembly is in its closed or open position. The deployable registers provide directional control for pull down conditions. Once the desired conditions are achieved, the deployable registers lower into the instrument panel and the other registers provide a larger opening to direct the air overhead at lower velocities keeping the vehicle cabin cool while not blowing in the direction of the occupants.
