  • Patent number: 10166986
    Abstract: A method for operating a drive device for a motor vehicle includes: during a coasting operation of the motor vehicle in which a shifting clutch is open and the internal combustion engine stands still starting the internal combustion engine in a first operating mode with the electric machine and in a second operating mode by at least partially closing the shifting clutch with a coupling torque set at the shifting clutch, thereby operatively connecting the internal combustion engine with at least one wheel, wherein the internal combustion engine is started in the first operating mode when a predictively determined wheel slip predictive value exceeds a wheel slip setpoint value, and wherein when the internal combustion engine is started in the second operating mode the electric machine is used for starting the internal combustion engine and for driving the at least one wheel when a wheel slip actual value exceeds the wheel slip setpoint value.
    Type: Grant

  • Patent number: 9862385
    Abstract: In a method of operating a drive device for a motor vehicle, a clutch is at least partly engaged, while an internal combustion engine of the drive device is inactive during coasting of the motor vehicle and the clutch is disengaged, to crank and thereby start the internal combustion engine with a clutch torque applied to the clutch. The clutch torque is hereby determined from a default wheel slip value which is based on a motor vehicle parameter.

  • Patent number: 6779967
    Abstract: A device for air mass flow control in a gas turbine engine includes at least one inlet duct 1, which can issue into an air duct 2, a counter-pressure duct 3, and a double-action shut-off element, which is connected between the counter-pressure duct 3 and the inlet duct 1 and is responsive to pressure differences between the two ducts to control air flow in the air duct 2.
