Patent number: 10029539Abstract: An air conditioning device for vehicle includes a refrigeration cycle including a compressor for sucking, compressing and discharging a refrigerant, a condenser for condensing the high-temperature and high-pressure refrigerant discharged from the compressor, an expansion valve for decompressing the refrigerant condensed in the condenser and an evaporator for evaporating the refrigerant through heat exchange between the refrigerant reduced in pressure by the expansion valve and surrounding air. This air conditioning device for vehicle increases an operation rate of the compressor more than that before a vehicle speed drops below a first permitted vehicle speed higher than a fuel cut recovery vehicle speed when an air conditioner is on, at which the compressor is actuated, when the vehicle speed drops below the first permitted vehicle speed during the deceleration of a vehicle associated with a fuel cut.Type: GrantFiled: April 30, 2013Date of Patent: July 24, 2018Assignee: NISSAN MOTOR CO., LTD.Inventors: Tetsuya Fuke, Tadashi Iwamoto, Takashi Watanabe, Yugo Motegi, Tetsuya Furumaya

Patent number: 9259992Abstract: A vehicle air conditioner control system has an air conditioning device has a compressor, a condenser, an expansion valve, and an evaporator, a compressor running rate control device, a deceleration fuel cutoff executing device, and a fuel supply recovery executing device that cancels cutoff of fuel supply and recovers fuel supply at a higher vehicle speed during vehicle deceleration fuel cutoff period with air-conditioner ON than during vehicle deceleration fuel cutoff period with air-conditioner OFF. The compressor running rate control device increases the compressor running rate for a predetermined period just before a fuel supply recovery time with air-condition ON during the deceleration fuel cutoff period more than during non-execution of the deceleration fuel cutoff, and subsequently decreases the compressor running rate at or just before the fuel supply recovery time with air-condition ON equal to or less than during non-practice of the deceleration fuel cutoff.Type: GrantFiled: June 14, 2012Date of Patent: February 16, 2016Assignee: Nissan Motor Co., Ltd.Inventors: Yugo Motegi, Tadashi Iwamoto, Takashi Watanabe, Tetsuya Fuke, Tetsuya Furumaya

Patent number: 8939869Abstract: Depression of an accelerator pedal by a vehicle operator in an operating condition in which fuel economy is deteriorated, is restrained. An actual opening degree of the accelerator pedal and a reference guide value of the accelerator pedal opening degree which allows a vehicle to accomplish both acceleration performance and fuel economy performance in a current operating condition are indicated in a display section together. In a case where a current gear ratio of a transmission is deviated from an optimal gear ratio of the transmission which is determined based on an operating condition of the vehicle, the reference guide value is changed such that engine output of the vehicle is decreased.Type: GrantFiled: June 6, 2012Date of Patent: January 27, 2015Assignee: Nissan Motor Co., Ltd.Inventor: Tetsuya Fuke

Patent number: 7006852Abstract: There is provided a power save processing method to be performed by a communication terminal capable of concurrently establishing communication links with a plurality of slave communication terminals, which reduces the transition time and provides an increased power save operation time. When a power save operation is performed at a plurality of slave communication terminals having asynchronous communication links established with the master communication terminal, the master communication terminal sets a communication start time and a communication duration for each communication link such that the communication slots used for the communication links are huddled together so as to span one continuous range, assuming that the communication links all have the same communication cycle. In accordance with the parameters thus set, the master communication terminal Negotiates with the plurality of slave communication terminals.Type: GrantFiled: September 30, 2003Date of Patent: February 28, 2006Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masaaki Morioka, Yoshitaka Arase, Tetsuya Fuke, Wataru Tachibana
