Patent number: 7677050Abstract: A control device for a fan motor (7) which cools a condenser (6) of a vehicle air conditioner includes a temperature sensor (12) which detects a temperature of an air that has passed through an evaporator (10) of the vehicle air conditioner; and a controller (2). The controller (2) functioning to calculate a reference value (Ds) of an airflow generated by a rotation of the fan motor (7); calculate a correction value (DUP, DUPT) of the airflow on the basis of the detected air temperature (Tair); set a target airflow (TDR) on the basis of the reference value (Ds) and correction value (DUP, DUPT) of the airflow; and control the rotation of the fan motor to effect the target airflow (TDR).Type: GrantFiled: January 18, 2005Date of Patent: March 16, 2010Assignee: Nissan Motor Co., Ltd.Inventors: Shigeyuki Sakaguchi, Makoto Fukubayashi, Yoichiro Nakahara, Tomofumi Furukawa

Patent number: 5944256Abstract: A vehicular air conditioner comprises a controller, a solar sensor and a room temperature sensor. The controller includes a correcting section where a detected solar intensity and/or a detected room temperature is corrected by a first-order lag filtering process. The controller executes an air conditioning control on the basis of the corrected solar intensity and/or room temperature so that the change of the air-conditioning state is fitted in accordance with feeling of vehicle occupants.Type: GrantFiled: May 23, 1996Date of Patent: August 31, 1999Assignee: Nissan Motor Co., Ltd.Inventors: Masashi Arai, Makoto Fukubayashi, Nobuyuki Kawai

Patent number: 5553775Abstract: An air conditioner system for a vehicle having an occupant compartment which includes a driver's occupying area and a front passenger's occupying area. The system includes a vent duct adapted to conduct a conditioned air. The vent duct defines a first passages opening to the driver's occupying area and a second passage opening to the front passenger's occupying area. First and second vent valves are disposed within the first and second passages, respectively. First and second actuators are drivingly connected to the first and second vent valves. A first sensor is so constructed and arranged as to detect insolation magnitude within the driver's occupying area and generate a first sensor signal indicative of the detected insolation magnitude within the driver's occupying area.Type: GrantFiled: November 22, 1994Date of Patent: September 10, 1996Assignee: Nissan Motor Co., Ltd.Inventors: Keno Kato, Ikutaro Noji, Masashi Arai, Makoto Fukubayashi

Patent number: 5349826Abstract: An air conditioning apparatus for an automotive vehicle comprises: a compressor (101) driven by an engine (101) for compressing a refrigerant; an evaporator (103) for evaporating the refrigerant compressed by the compressor; engine speed commanding section (104) for outputting a first command signal to drive the engine at a first engine idle speed when the compressor is not actuated and outputting a second command signal to drive the engine at a second engine idle speed higher than the first engine idle speed when the compressor is actuated; an after-evaporator temperature sensor (105) for detecting air temperature Immediately after the evaporator; an external air temperature sensor (106) for detecting external air temperature; and an inhibiting section (107) for inhibiting the engine speed commanding section from outputting the second command signal, when after-evaporator temperature is lower than a predetermined temperature and further external air temperature is lower than another predetermined temperatureType: GrantFiled: September 2, 1993Date of Patent: September 27, 1994Assignee: Nissan Motor Company, Ltd.Inventors: Nobuyuki Kawai, Ikutaro Noji, Makoto Fukubayashi

Patent number: 5216895Abstract: In an engine idle speed control system associated with an air conditioner provided with an evaporator for evaporating a refrigerant compressed by a compressor actuated or deactuated by an engine near an evaporator freeze limit temperature, the engine idle speed is increased under consideration of thermal load applied to the compressor whenever the compressor is being actuated. The compressor 21 is deactuated when the temperature of air having passed through the evaporator 22 drops below a predetermined value, and actuated when the same temperature rises beyond another higher predetermined value. Whenever the compressor 21 has been deactuated, the time interval between the deactuation and the actuation of the compressor is measured. If the measured time interval is relatively short, since this indicates a relatively high thermal load applied to the compressor, the engine idle speed is increased.Type: GrantFiled: September 3, 1992Date of Patent: June 8, 1993Assignee: Nissan Motor Co., Ltd.Inventors: Nobuyuki Kawai, Ikutaro Noji, Makoto Fukubayashi, Shozo Nakayama, Naoki Nakada, Kazuhiro Ishigami, Kazuya Takahashi

Patent number: 5014522Abstract: An automotive air tempering apparatus for use in an automotive vehicle having a duct through which air is directed into a passenger compartment. The apparatus comprises an air chilling unit including an evaporator provided in the duct and a compressor having a displacement variable for supplying a controlled amount of refrigerant to the evaporator for chilling the air in the duct. A control unit controls the displacement of the compressor to bring the refrigerant temperature to a target value when air is introduced into the duct from the atmosphere. The control unit controls the displacement of the compressor to bring the chilled air temperature to a target value when air is introduced into the duct from the passenger compartment.Type: GrantFiled: April 17, 1990Date of Patent: May 14, 1991Assignee: Nissan Motor Co., Ltd.Inventors: Ikutaro Noji, Masaki Kaiju, Hideyuki Sakamoto, Makoto Fukubayashi
