Patent number: 9376099Abstract: 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.Type: GrantFiled: July 12, 2013Date of Patent: June 28, 2016Assignee: Ford Global Technologies, LLCInventors: Manfred Koberstein, Tina Maurer, Stephen R.

Patent number: 8944201Abstract: An operator's cab for a shuttle car including a cab frame, a window assembly, and a pressurization system. The cab frame defines an interior chamber and an opening. The window assembly includes a pane and a pane seal. The pane is coupled to the cab frame such that the pane covers the opening and encloses the interior chamber. The pane seal is positioned between the pane and the cab frame. The pressurization system provides a positive pressure in the interior chamber relative to the surrounding environment. The pressurization system includes a blower and a motor for driving the blower. The blower is in fluid communication with the interior chamber.Type: GrantFiled: February 9, 2012Date of Patent: February 3, 2015Assignee: Joy MM Delaware, Inc.Inventors: James Krellner, Ronald K. Dickey, David P. Paich

Patent number: 8944145Abstract: A vehicle seat air-conditioner includes a seat on which an occupant sits, a heat exchanger that adjusts the temperature of a conditioned gas, a blower that supplies the conditioned gas to the seat, a seat covering layer provided on a surface of the seat and facing the seated occupant, and a flow channel provided on an underside of the seat covering layer that pass the conditioned gas that is introduced by the blower. The vehicle seat air-conditioner is adapted to convey heat of the conditioned gas to an occupant side of the seat covering layer by directly blowing out a portion of the introduced conditioned gas to the occupant side of the seat covering layer, and to perform heat exchange with the occupant side of the seat covering layer by circulating a portion of a remainder of the conditioned gas through the flow channel.Type: GrantFiled: September 30, 2010Date of Patent: February 3, 2015Assignee: Honda Motor Co., Ltd.Inventor: Hidenori Esaki

Patent number: 8931547Abstract: A vehicle air conditioning system includes an electric powered refrigerant compressing device, an evaporator, an electric heater, an air temperature determining component, a cabin interior temperature controlling component, an upper limit electric power setting component, and an electric power distribution controller. The evaporator receives refrigerant from the compressing device. The heater is downstream of the evaporator in an air passageway. The determining component determines a first air temperature upstream of the evaporator and a second air temperature between the evaporator and the heater. The controlling component sets a vehicle interior discharge air temperature at a position downstream of the heater to a target temperature. The power setting component sets an upper limit for power supplied to the compressing device and the heater.Type: GrantFiled: June 8, 2011Date of Patent: January 13, 2015Assignee: Nissan Motor Co., Ltd.Inventors: Tzu-Hsiang Yen, Takayoshi Matsuoka, Takafumi Uehara

Patent number: 8931545Abstract: A heat exchanger arrangement is provided for an internal-combustion engine having a heat engine, which converts hot steam of a working medium by way of an expansion device to kinetic energy. The working medium, that can be delivered by a pump, can be heated in a first heat exchanger by a coolant and in a second heat exchanger by an exhaust gas of the internal-combustion engine. In the delivery direction, the working medium first flows through the first heat exchanger and, subsequently, through the second heat exchanger. The exhaust gas can flow through the first heat exchanger.Type: GrantFiled: March 18, 2009Date of Patent: January 13, 2015Assignee: Bayerische Motoren Werke AktiengesellschaftInventors: Raymond Freymann, Wolfgang Strobl, Walter Huebner, Andreas Obieglo, Peter Doemeland, Norbert Kraus, Juergen Becker, Michael Hoetger, Christian Goebel, Goeran Gensicke
