Publication number: 20150134171Abstract: A control device is configured to control an engine to be started and stopped such that when a hybrid vehicle is required to output a vehicular required power smaller than an engine starting threshold value the control device operates to stop the engine and use only a motor generator to cause the vehicle to travel and when the vehicular required power exceeds the threshold value the control device operates to start the engine and use both the engine and the motor generator to cause the vehicle to travel. The engine starting threshold value is set to be higher when at least one of an amount of lifting the intake valve and a working angle on the intake valve controlled by a VVL device provided to the engine is small than when at least one of the amount and the angle is large.Type: ApplicationFiled: October 30, 2014Publication date: May 14, 2015Inventors: Yoshikazu Asami, Toshikazu Kato, Ryuta Teraya

Publication number: 20150134161Abstract: A hybrid electric vehicle includes an engine and an electric machine, both capable of providing propulsion power. A clutch is configured to selectively couple the engine to the electric machine. At times, the vehicle may be subject to excessive loads, such as a large amount of weight in the vehicle or the vehicle towing another object. At least one controller is programmed to engage the clutch and start the engine in response to a load of the vehicle exceeding a predetermined threshold and a release of the brake pedal while the vehicle is stopped and in drive. This increases available engine torque prior to vehicle launch in anticipation of an upcoming acceleration demand.Type: ApplicationFiled: November 11, 2013Publication date: May 14, 2015Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Mark Steven YAMAZAKI, Wei LIANG, Xiaoyong WANG, Rajit JOHRI, Ryan Abraham MCGEE, Ming Lang KUANG

Patent number: 9028366Abstract: A hybrid vehicle in which at least two shift ranges can be selected for a single running direction includes an engine, a motor generator, an EHC raising the temperature of a catalyst for cleaning up an exhaust gas from the engine, and an ECU. While the vehicle is running, if the engine is stopped and, of the two shift ranges, a shift range where larger decelerating force is produced by regenerative braking of the motor generator has been selected, the ECU causes the EHC to raise the temperature of the catalyst using electric power generated by the motor generator.Type: GrantFiled: February 16, 2011Date of Patent: May 12, 2015Assignee: Toyota Jidosha Kabushiki KaishaInventor: Keita Hashimoto

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: 9022165Abstract: A method of controlling a fluid pump to supply lubricating fluid to a plurality of fluid requiring components in a hybrid vehicle powertrain includes selecting a component-required flow rate for each respective component using a determined operating speed and torque for that respective component. Once the each component-required flow rate is selected, the system flow rate is set to the maximum component-required flow rate of the plurality of component-required flow rates. The fluid pump is then commanded to supply fluid to each of the plurality of fluid requiring components at the system flow rate.Type: GrantFiled: July 3, 2012Date of Patent: May 5, 2015Assignee: GM Global Technology Operations LLCInventors: Jy-Jen F.
