Patent number: 8688350Abstract: A hybrid powertrain includes a combustion engine, an electric machine arrangement, a gearbox operable to receive motive power from at least one of the combustion engine and the electric machine arrangement for providing motive power to a load of the powertrain. The powertrain is configurable in operation so that its combustion engine is switchable between an inactive state and an active state. The combustion engine is cranked to switch it from its inactive state to its active state. Application of cranking torque to the combustion engine is controlled in operation to substantially temporally coincide with a gear change in the gearbox.Type: GrantFiled: March 20, 2013Date of Patent: April 1, 2014Assignee: Volvo Technology CorporationInventors: Lars Carlhammar, Svante Karlsson, Helene Panagopoulos

Patent number: 8682562Abstract: This invention relates generally to gas turbine engine thrust scheduling, and more particularly to systems and methods for smoothing thrust inputs to gas turbine engines. In one embodiment, a method for operating a gas turbine engine comprises, upon disengagement of an auto-throttle system, determining a first trim setting corresponding to a TLA setting, determining a second trim setting where the second trim setting reduces to zero during successive manual throttle lever movements, determining a third trim setting comprising a combination of the first trim setting and the second trim setting, and applying the third trim setting to the TLA setting to smoothly transition from auto-throttle to manual operation of the engine while maintaining engine thrust.Type: GrantFiled: May 7, 2010Date of Patent: March 25, 2014Assignee: Rolls-Royce CorporationInventor: Angela J. Shepler

Patent number: 8676417Abstract: A method for managing a threshold increase in output torque capability in a vehicle includes detecting the threshold increase in output torque capability using a controller, and automatically limiting, via the controller, a rate of change of an actual output torque from a transmission of the vehicle in response to the threshold increase. The actual output torque is provided via a traction motor solely using battery power from an energy storage system. The method may include calculating a difference between the threshold increase and the actual output torque, and limiting the rate of change using a rate that is proportional to the difference. A vehicle includes the ESS, a transmission, and a controller. An output member of the transmission is powered using electrical energy from the ESS. The controller manages an increase in output torque capability as noted above.Type: GrantFiled: February 17, 2011Date of Patent: March 18, 2014Assignee: GM Global Technology Operations LLCInventors: Michael Arnett, Alexander K. Rustoni, Sean W. McGrogan, Goro Tamai

Patent number: 8676469Abstract: A vehicle drive motor control system is provided, which, when a vehicle drive motor is in a locked state, may urge a driver to make a switch from actuation of an accelerator to actuation of a brake, thereby preventing thermal damage to coils inside the motor. The vehicle drive motor control system is capable of, when a vehicle drive motor is in a locked state as a result of actuating an accelerator, making the vehicle slowly move backward (or providing other stimulus to the driver) by decreasing a maximum drive torque value. This may effectively cause the driver to make the switch from actuation of the accelerator to actuation of the brake.Type: GrantFiled: January 12, 2012Date of Patent: March 18, 2014Assignee: Suzuki Motor CorporationInventor: Akiyoshi Ohno

Publication number: 20140074372Abstract: An ECU includes a collision determination unit, a condition determination unit, and an output suppression unit. The collision determination unit monitors an acceleration detected by a collision sensor, and determines that a vehicle collision has occurred when the acceleration is greater than a predetermined value. The condition determination unit determines whether or not a vehicular speed absolute value is smaller than a threshold vehicular speed in a determination period lasting from the determination of collision for a predetermined time. The output suppression unit suppresses an output of a vehicle driving force when the vehicular speed absolute value is smaller than the threshold vehicular speed in the determination period.Type: ApplicationFiled: May 12, 2011Publication date: March 13, 2014Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keiji Kaita, Takeshi Hoshiba, Takahiko Hirasawa

Publication number: 20140074353Abstract: A method of controlling a telematics system based on the ignition state of an engine in a vehicle. The ignition state of the engine can alternate between an on state and an off state. The method includes monitoring, by a processor a voltage level on a diagnostics connector from the vehicle and monitoring, by the processor, an indicator of engine activity such as revolutions per minute, from the diagnostics connector of the vehicle. The method also includes determining, by the processor, a condition of the ignition state of the engine of the vehicle based on the voltage level and the indicator of engine activity and changing the operating mode of the telematics system based on the ignition state of the engine. The operating mode of the telematics system can alternate between a first mode and a second mode, in which power consumption is higher than in the first mode.Type: ApplicationFiled: September 12, 2013Publication date: March 13, 2014Inventors: Jin Lee, Albert Bae, Jeff Lim, John Kim
