Patent number: 8784263Abstract: A hybrid driving apparatus includes a diesel engine outfitted with an exhaust brake, and a clutch between the diesel engine and a hybrid motor. The exhaust brake is shiftable between an operational state and a non-operational state, and a switch is operable to change the exhaust brake from the non-operational state to the operational state. The switch is configured to automatically change the exhaust brake which is in the operational state while the vehicle is turned on to the non-operational state when the vehicle is turned off. The clutch is automatically changed from an engaged condition, in which the diesel engine and the hybrid motor are connected, to the disengaged condition, in which the diesel engine and the hybrid motor are disconnected, when the vehicle decelerates while the exhaust brake is in the non-operational state.Type: GrantFiled: November 22, 2011Date of Patent: July 22, 2014Assignees: Aisin Seiki Kabushiki Kaisha, Aisin Technical Center of America, Inc.Inventors: Tomoya Takahashi, Kazuhiro Irie, Kazushi Konno

Patent number: 6651450Abstract: If a motor breaks down, an appropriate measure is taken according to the type pf the breakdown. If the breakdown is judged to be due to abnormal energization of the motor by electrical abnormality judgment means, a drive source for a hybrid compressor is secured while preventing an engine for traveling from stopping by compressor operation continuation means. If it is judged that the driven state of the motor is abnormal, the hybrid compressor is disconnected from the engine to protect the engine from mechanical abnormality of the hybrid compressor.Type: GrantFiled: February 20, 2002Date of Patent: November 25, 2003Assignee: Zexel Valeo Climate Control CorporationInventors: Masahiko Tamegai, Kazuhiro Irie

Patent number: 6375436Abstract: A hybrid compressor achieving simplification in the structure and capable of driving the compression unit with ease is provided. An electromagnetic clutch unit (40) is provided at a rotating shaft (11) projecting out on one side of a compression unit (10) and an electric motor unit (70) is provided at the rotating shaft (11) projecting out on the other side of the compression unit (10), so that an electromagnetic clutch unit (40) in the prior art can be utilized directly. At the same time, since the electric motor unit (70) is provided at the rotating shaft (11) projecting out the other side of the compression unit (10), the electromagnetic clutch unit and the electric motor unit are set at the same rotating shaft (11) and the compression unit (10) and the electric motor unit (70) are positioned next to each other to reduce the torsional torque generated at the rotating shaft (11).Type: GrantFiled: June 8, 2000Date of Patent: April 23, 2002Assignee: Zexel CorporationInventors: Kazuhiro Irie, Yukio Sakurai, Yasutaka Negishi, Masahiko Tamegai
