Patent number: 9033850Abstract: A method of operating a drive-train of a vehicle that comprises a combustion engine whose torque for driving the vehicle can be transmitted to a drive output via a transmission, with a hydraulically actuated clutch when the clutch is engaged. An electric machine provides torque which can act upon the drive-train. The clutch is closed by filling the clutch with hydraulic fluid through a circuit by way of a pump which can be driven by the engine and the electric machine. The method is to engage the clutch when the combustion engine is initially off and/or when the electric machine is initially switched off, determining a driving dynamic based on the behavior of the driver and adjusting the speed of the electric machine based on the determined driving dynamic such that the greater the determined driving dynamic is, the more rapidly the clutch is filled by the pump.Type: GrantFiled: September 4, 2013Date of Patent: May 19, 2015Assignee: ZF Friedrichshafen AGInventor: Martin-Joachim Bader

Publication number: 20150134159Abstract: A hybrid vehicle is provided that includes an engine, a reversible electric machine capable of generating and providing electric power, and a clutch for selectively engaging the engine to the electric machine. While the vehicle is traveling, an operator of the vehicle may release (“tip-out”) the accelerator pedal, indicating a desire for a reduction in speed and/or acceleration of the vehicle. If the clutch is engaged during the tip-out, the at least one controller is programmed to disengage the clutch and alter a commanded torque to the electric machine in response to the tip-out of the accelerator pedal to simulate compression braking of the engine. If the vehicle is operating in an electric-only mode of propulsion during the tip-out, and if a state-of-charge of the battery is relatively high, the controller is programmed to activate the engine and provide compression torque to the driveline in response to the tip-out.Type: ApplicationFiled: November 8, 2013Publication date: May 14, 2015Applicant: FORD GLOBAL TECHNOLOGIES, LLCInventors: Rajit JOHRI, Mark Steven YAMAZAKI, Xiaoyong WANG, Wei LIANG, Ryan Abraham McGEE, Ming Lang KUANG
