  • Publication number: 20150149010
    Abstract: An engine start using an electric motor during a vehicle travel is performed by increasing an output torque of the electric motor in a slip state where a second frictional engagement element 3 connecting the electric motor 1 and a driving wheel slips. A controller determines a requested acceleration amount from a depression amount of an accelerator pedal. When the requested acceleration amount is significant, a different torque increment characteristic is applied, compared to a case where the requested acceleration amount is not significant. Thus, the internal combustion engine starts in a high response depending on the requested acceleration amount input by the driver, thereby improving a vehicle acceleration response.

  • Patent number: 9033850
    Abstract: 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.

    Abstract: A hybrid vehicle operates in an electric-drive-only mode and one or more modes using an internal combustion engine. A control pedal is movable to respective positions by a driver for indicating a desired vehicle motion. A controller selectably activates the engine according to instantaneous values of a variable wheel output demand and a variable pull-up threshold. The pedal position is converted to a respective instantaneous wheel output demand in response to an initial value from a mapping relationship that is modified in response to a difference between the initial value and the variable pull-up threshold. The pull-up threshold may preferably be dynamically determined according to a state of charge of a battery for powering the electric drive. The modification to the wheel output demand preferably reduces the slope of the mapping relationship near the pull-up threshold to reduce pedal position sensitivity in a region near the dynamically varying pull-up threshold.

    Abstract: A vehicle includes a starter motor, an engine having an output mechanically coupled to the starter motor, a transmission having an input, and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and the output of the engine, and at least one controller. The at least one controller is programmed to initiate an engine start based on driver demand. The controller is further configured to enable pressure to the clutch for the engine start if driver demand is less than a calibratable torque value or enable the starter motor for the engine start if the driver demand is greater than a calibratable torque value. The controller may lock the clutch to the output of the engine in response to the speed of the engine being approximately equal to the speed of the electric machine.

  • Publication number: 20150112523
    Abstract: A vehicle includes an engine having a crankshaft, a transmission having an input, and an electric machine mechanically coupled to the transmission input. The vehicle further includes a clutch configured to mechanically couple the electric machine and engine crankshaft, and at least one controller. The at least one controller, in response to an engine start condition and subsequent partial engagement of the clutch, outputs a torque command for the electric machine to increase the speed of the crankshaft to a speed of the electric machine before commanding fuel injection of the engine. The torque command is based on driver demanded torque and a change in speed of the crankshaft caused by changes in pressure to the clutch.

    Abstract: A vehicle is provided with a powertrain including an electric motor, an internal combustion engine, and a turbocharger. The vehicle further includes a controller programmed to apply a variable filter to engine torque commands that are responsive to driver demand. The filter affects commands having a rate of increase greater than a predetermined threshold such that corresponding rates of increase in both engine torque and turbocharger speed are limited to respective rates less than the maximum available levels in order to reduce a surge in engine output emissions. The controller additionally issues commands for motor torque such that overall powertrain torque satisfies the driver demand.
