Patent number: 9026285Abstract: A battery charging method for a hybrid vehicle and the hybrid vehicle using the same are disclosed. The hybrid vehicle includes an engine and a motor as power source and includes the battery in which electrical energy for driving the motor is stored. The method and system may include: determining whether the battery needs to be charged while the vehicle is stopped; transitioning a transmission to a neutral position (N position) when the battery needs to be charged; starting the engine and engaging an engine clutch to connect the engine with the motor so that the motor generates electrical energy via power from the engine. The electrical energy generated by the motor is then stored in the battery accordingly.Type: GrantFiled: June 27, 2012Date of Patent: May 5, 2015Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Gwang Seob Shin, Yeonho Kim

Patent number: 8790207Abstract: A hydraulic control system of an automatic transmission for a hybrid vehicle provides for simplifying structure of a valve body and improving responsiveness as a consequence of directly controlling hydraulic pressure supplied to friction elements. The hydraulic control system may operate first and second clutches and first and second brakes selectively according to each driving mode, and may include: a first proportional control solenoid valve for selectively supplying forward pressure and reverse pressure supplied from a manual valve to the first clutch; a second proportional control solenoid valve for selectively supplying line pressure supplied from a primary regulator valve to the second clutch; a third proportional control solenoid valve for selectively supplying the line pressure supplied from the primary regulator valve to the first brake; and a fourth proportional control solenoid valve for selectively supplying the forward pressure supplied from the manual valve to the second brake.Type: GrantFiled: June 29, 2011Date of Patent: July 29, 2014Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Gwang Seob Shin, Jong Hyun Kim, Youngchul Kim, Jang Mi Lee, Yeonho Kim, Jaeshin Yi
