Patent number: 8463492Abstract: A system for controlling air-conditioning in a vehicle includes an input, a sensor, a first offset module, and an evaporator temperature control module. The input receives an input temperature. The first sensor measures a first dewpoint temperature of air adjacent to a windshield of the vehicle. The first offset module generates a second dewpoint temperature based on the input temperature and generates a first offset based on the first and second dewpoint temperatures. The evaporator temperature control module generates a target evaporator temperature based on the first offset.Type: GrantFiled: May 26, 2009Date of Patent: June 11, 2013Assignee: Chrysler Group LLCInventors: Mark A. Hill, Alfred Jeckel, Curt O'Donnell, Mark Bigler, Holgar Krah, Lance Tagliapietra

Patent number: 8301335Abstract: A system for controlling air-conditioning of a vehicle includes an input, an offset generator module, and an evaporator temperature control module. The input receives an input temperature. The offset generator module receives a psychrometric parameter of air inside the vehicle and generates offsets based on the input temperature and the psychrometric parameter. The evaporator temperature control module generates a target evaporator temperature based on the offsets.Type: GrantFiled: May 26, 2009Date of Patent: October 30, 2012Assignees: Chrysler Group LLC, Daimler AGInventors: Mark A. Hill, Alfred Jeckel, Curt O'Donnell, Mark Bigler, Lance Tagliapietra

Publication number: 20100025125Abstract: In a method and apparatus for the operation of a vehicle having a battery with a plurality of series or parallel connected individual cells, a coolant flows through the respective cell housings and/or a battery housing that encloses the entire battery. The coolant is delivered within a coolant circuit by a pump unit, and is thermally coupled with a refrigerant circuit through a heat exchanger. A refrigeration compressor placed in the refrigerant circuit is thermally coupled with the coolant circuit through the heat exchanger, depending on a current ambient temperature and/or a current speed of the vehicle. The speed of the refrigeration compressor may be regulated depending on the current ambient temperature and/or the current speed of the vehicle.Type: ApplicationFiled: August 1, 2008Publication date: February 4, 2010Applicant: Daimler AGInventors: Reyk Bienert, Alfred Jeckel

Publication number: 20060144061Abstract: In a method for operating a climate control system in a passenger compartment of a motor vehicle, the climate control system can be operated in a recirculation mode in which recirculated air is supplied to the passenger compartment or in fresh air mode in which at least a portion of the air supplied to the passenger compartment is fresh air. In its normal operating mode the climate control system is operated in recirculation mode. Upon exceeding a predetermined CO2-threshold value measured in the passenger compartment of the motor vehicle the climate control system is switched to fresh air mode.Type: ApplicationFiled: November 22, 2003Publication date: July 6, 2006Inventors: Sean Badenhorst, Alfred Jeckel, Berthold Johner

Patent number: 6078853Abstract: A device for use in vehicles with electric or hybrid drive for monitoring the air conditioning of a vehicle based on health and energy consumption readings. The device monitors the operation of the air conditioning to determine when differentials between outside and inside temperature are excessive, and/or inside atmospheric humidity is too low and/or air quality is poor. An occurrence of any of these conditions results in the system suggesting to the driver that he should interrupt travel to the desired destination. In addition, if necessary, the device performs a vehicle range estimate as a function of the selected air conditioning operation.Type: GrantFiled: April 16, 1998Date of Patent: June 20, 2000Assignee: DaimlerChrysler AGInventors: Andreas Ebner, Wolfgang Henseler, Juergen Heuberger, Alfred Jeckel, Jan Martin

Patent number: 5603476Abstract: A filter holder assembly is provided for the optional holding in a motor vehicle at a dust filter alone or a dust filter and an absorption filter which is optionally arranged directly downstream of the dust filter. A frame lower part is provided which either holds the dust filter or the absorption filter. When the frame lower part holds the absorption filter, a frame upper part which holds the dust filter is releasably arranged upstream of the frame lower filter.Type: GrantFiled: July 14, 1995Date of Patent: February 18, 1997Assignee: Mercedes-Benz AGInventors: Helmut Merk, Alfred Jeckel, Thomas Dietterle

Patent number: 5221231Abstract: A motor vehicle heating/air-conditioning system of a motor vehicle has a water-removal device arranged in the fresh-air inlet duct, rising from the duct base and comprising a coarse-mesh lattice and a fine-mesh lattice resting against the latter. The water removed is carried away downwardly on the webs of the coarse-mesh lattice to the duct base which forms a water collection point with water drainage. In order to combine a favorable water-removal function with a good air-guidance function, the coarse-mesh lattice facing the incident air represents an air guide with predetermined throughflow and is pleated in a corrugated shape. A channel spanned by the fine-mesh lattice arranged in at least some areas is in each case formed between two upwardly-directed corrugation troughs. The water-removal device is placed in the region of a duct widening provided by a set-back wall portion, such that the water-removal device ends at a distance from the set-back wall portion.Type: GrantFiled: December 20, 1991Date of Patent: June 22, 1993Assignee: Mercedes-Benz AGInventor: Alfred Jeckel

Patent number: 5162019Abstract: Air-permeable and water-permeable baffles in the form of a fine-meshed grill are mounted in front of the upwardly projecting side walls in a motor vehicle fresh-air intake duct in order to improve separation with an inlet grill retaining any coarse impurities and with at least one drainage aperture, located in the area of the lowest point of the fresh-air intake duct, for liquid separated out from the air current. The liquid making its way through the meshes of the grills flows, in the flow vacuum between baffle and side wall at the back of the baffle, downwards to the duct bottom and the drainage aperture.Type: GrantFiled: December 20, 1991Date of Patent: November 10, 1992Assignee: Mercedes-Benz AGInventors: Peter Widmaier, Alfred Jeckel, Rolf Kohler
