  • Patent number: 10214073
    Abstract: Agricultural machines such as sprayers can be improved by providing a control system configured to adjust an engine cooling package fan with variable speeds, to thereby minimize parasitic losses, based on progress of the HVAC system for attaining a desired temperature in the operator cab. In one aspect, as a gap between actual and desired temperatures (temperature differential) in the cab minimizes, the cooling package fan can be variably adjusted to increase or decrease in speed, depending on heating or cooling occurring in the cab, respectively. However, if a temperature of an area in the engine compartment reaches a predetermined threshold, such variable speed control can cease, and the cooling package fan can instead be controlled to cool the area.

    Abstract: A vehicular air conditioner capable of reducing high-frequency sounds generated when an air mix damper is slightly opened and finely adjusting the temperature around the maximum heating position for improving the temperature controllability is provided. The vehicular air conditioner including an air mix damper that adjusts a flow rate of air delivered into a heating passage including a heater core after being passed through an evaporator and a flow rate of air delivered into a bypass passage that bypasses the heater core. In the vehicular air conditioner, a plurality of asperity portions are formed on a distal-end-side surface of the damper in the width direction of the damper, at which the damper is in contact with a seal surface on a unit case at the maximum heating position, and an elastic insulator having a predetermined thickness is attached to the asperity portions to form asperities similar thereto.

  • Patent number: 9403530
    Abstract: An air flow sensor chip-heating control device and method of a diesel hybrid electric vehicle controls whether an air flow sensor installed in an engine intake system of the diesel hybrid electric vehicle performs a chip-heating operation. Particularly, the air flow sensor chip-heating control device performs a chip heating operation of the air flow sensor based on a result obtained by deciding a driving history of an engine when the vehicle enters into a hybrid mode during driving of the engine.

  • Patent number: 9376099
    Abstract: A method and system for the cancellation of transmission shift delay as a function of an optimum target temperature is disclosed. Once the pre-selected optimum target is achieved, the shift delay is cancelled and the transmission is upshifted. Thus the disclosed inventive concept is based on the cancellation of the shift delay on achieving climate control air conditioning comfort targets. Such comfort targets could include one or more of the measured HVAC evaporator temperature, the HVAC discharge temperature, or the in-vehicle cabin temperatures. When a temperature sensor measuring the selected temperature reaches the pre-selected target temperature the shift delay may be cancelled and the transmission may be upshifted, thus maximizing passenger comfort while minimizing fuel consumption. Having the shift delay based upon the achievement of specific measurable comfort targets in the form of target temperatures rather than on a set time period allows optimization between cabin comfort and fuel efficiency.

  • Patent number: 9221318
    Abstract: An air conditioner for a vehicle includes a casing having therein first and second air passages through which outside air and inside air flow respectively. A heating heat exchanger is arranged in the first and second air passages to heat air. First and second air mix doors are arranged respectively in the first and second air passages to adjust a ratio between a flow amount of air passing through the heating heat exchanger and a flow amount of air bypassing the heating heat exchanger. Each of the first and second air mix doors is a slide door in which a plate door body part slides in a direction being applied by its own weight. The second air mix door slides in a sliding direction inclined relative to a sliding direction of the first air mix door by an angle toward a horizontal direction.
