Patent number: 5991683Abstract: The present invention prevents a decrease in efficiency due to energy circulation in a power transmission path in a power output apparatus having an engine and a motor as power source. In the power output apparatus, a planetary gear 120 has a sun gear shaft linked with a generator MG1, a ring gear shaft linked with a motor MG2, and a planetary carrier linked with an output shaft of an engine 150. The power output apparatus carries out a control procedure to avoid energy circulation, which goes through the planetary gear 120, the motor MG2, and generator MG1, and the planetary gear 120, and thereby prevent a decrease in efficiency. The energy circulation occurs when the motor MG2 converts the power output from the engine 150 to electric power and the generator MG1 carries out power operation with the regenerated electric power.Type: GrantFiled: March 13, 1998Date of Patent: November 23, 1999Assignee: Toyota Jidosha Kabushiki KaishaInventors: Toshifumi Takaoka, Takahiro Nishigaki, Masakiyo Kojima, Hiroshi Kanai, Kenichi Nagase, Shinichi Abe, Yukio Kobayashi, Katsuhiko Yamaguchi, Osamu Harada

Patent number: 5604304Abstract: A memory stores and holds both the number of crankshaft angle pulse signals occurring after detecting a reference portion when an engine stops and data relating to whether the reference portion which is supposed to be next detected upon re-start of the engine is a reference position of the camshaft. When the engine is re-started, it is determined whether a reverse rotation of the crankshaft across the reference position happened by comparing a predetermined value with the total obtained by adding the number of pulse signals stored in the memory and the number of pulse signals occurring until the reference portion is first detected again. When such reverse rotation happened, the reference position of the camshaft is shifted by 360.degree. CA. Therefore, regardless of whether such reverse rotation across the reference position happened or not, the engine timing cycle is again precisely synchronized.Type: GrantFiled: March 27, 1996Date of Patent: February 18, 1997Assignee: Nippondenso Co., Ltd.Inventors: Naoki Kokubo, Koji Sakakibara, Koichi Kamabora, Kenichi Nagase

Patent number: 5018362Abstract: An automotive air conditioner controller for controlling the operation of an automotive air conditioner employing a variable displacement compressor capable of gradually or continuously varying its displacement. While the engine of the automobile is idling, the automotive air conditioner controller adjusts the displacement of the compressor to or near to the maximum, varies desired idling speed of the engine according to required cooling ability, and adjusts the actual idling speed of the engine to the desired idling speed. Thus, the engine operates at an improved fuel consumption rate without reducing the cooling ability of the automotive air conditioner.Type: GrantFiled: November 28, 1989Date of Patent: May 28, 1991Assignee: Nippondenso Co., Ltd.Inventors: Kenichi Nagase, Hiroshi Haraguchi, Toshiaki Mizuno, Takayuki Kamada
