Patent number: 9211855Abstract: When the fuel supply to an internal combustion engine has stopped due to a vehicle starting to decelerate or the like, and the speed of the vehicle is greater than a predetermined speed, then a controller causes a power generator to operate in a first power generating mode. The controller charges a capacitor by using regenerative power that is output from the power generator to supply power from the power generator to the capacitor via a DC-DC converter. When the stopping of the fuel supply to the internal combustion engine is cancelled as a result of the engine revolution speed reaching a predetermined revolution speed (for example, an idling revolution speed) in conjunction with the speed of the vehicle dropping to the predetermined speed, the power generator can be kept in the first power generating mode.Type: GrantFiled: June 25, 2014Date of Patent: December 15, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Yasuhiro Hara, Hideto Yamamoto, Tomohiro Arakawa
