Patent number: 11335922Abstract: An energy conversion system includes an energy converter, a cold generator, and a liquid water obtainer. The energy converter is configured to convert energy of a source from one form to another form and generate heat and water vapor. The cold generator is configured to generate cold using the heat generated by the energy converter. The liquid water obtainer is configured to condense the water vapor using the cold to obtain liquid water. Accordingly, the water vapor generated from the energy converter can be cooled efficiently. Therefore, efficiency in obtaining the liquid water can be improved compared with a case where the water vapor is cooled by open air.Type: GrantFiled: December 17, 2019Date of Patent: May 17, 2022Assignees: DENSO CORPORATION, TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takuya Fuse, Kazutoshi Kuwayama, Hisao Nagashima, Kazutoshi Nishinakamura, Manabu Orihashi, Masakatsu Tsubouchi

Patent number: 10220826Abstract: A drive control apparatus includes a motor control unit and a gear shift control unit, and controls a power transmission system including first and second motors and a gear shift mechanism. When the gear shift mechanism is changed from a first gear stage to a second gear stage during deceleration of the vehicle, the motor control unit controls the first motor to be at a target rotation speed determined based on a gear ratio of a second power transmission gear and a rotation speed of an output shaft, and controls a second motor such that required brake torque is generated by the second motor. The gear shift control unit controls the gear shift mechanism so as to be in a neutral state in which power is not transmitted between an input shaft and the output shaft, until a rotation speed of the first motor becomes the target rotation speed.Type: GrantFiled: June 29, 2016Date of Patent: March 5, 2019Assignee: DENSO CORPORATIONInventors: Tomohiro Saito, Hiroshi Okada, Yukihiro Jo, Kazutoshi Nishinakamura

Patent number: 8731760Abstract: A vehicle driving system control apparatus includes a regeneration control section that performs a regeneration control when a vehicle is decelerated. In the regeneration control, the regeneration control section drives at least one of a first motor generator and a second motor generator with a power of an axle so as to charge a battery with an electric power generated with the at least one of the first motor generator and the second motor generator. The regeneration control section selects a mode of the regeneration control by controlling engagement and disengagement statuses of first to third clutches in correspondence with at least one of a target energy regeneration amount, a required brake torque and a vehicle speed.Type: GrantFiled: December 24, 2012Date of Patent: May 20, 2014Assignee: Denso CorporationInventors: Kazutoshi Nishinakamura, Hiroshi Okada, Tomohiro Saito, Hiroyuki Usami, Hitoshi Noguchi
