    摘要: A vehicle having an electric powertrain includes a control system for executing a driveline stability control method. A host machine determines vehicle speed prior to an electric-only (EV) mode or EV mode shift/transition, filters an initial motor torque command to the traction motor via a notch filter as a function of vehicle speed to generate a filtered motor torque command, and controls the motor during the EV mode or transition using the filtered motor torque command. The notch filter may have a center frequency and/or a damping coefficient tunable to changing vehicle speed. A control system for the vehicle includes the host machine, a notch filter, and optionally a vehicle speed-based active damping module. The host machine controls the motor during the EV mode or transition using the filtered motor torque command from the filter, and may provide the damping control during the EV mode or transition.

    摘要: A powertrain for a hybrid vehicle includes a clutch interconnecting an internal combustion engine and an electric motor. The electric motor is coupled to a manually operated gearbox operable in at least one electric only drive position and at least one hybrid drive position. A latch is coupled to the clutch and is moveable between a closed position inhibiting the clutch from interconnecting the internal combustion engine and the electric motor when the gearbox is disposed in the electric only drive position, and an open position allowing the clutch to interconnect the internal combustion engine and the electric motor when the gearbox is disposed in the hybrid drive position.

    摘要: A vehicle has a multi-gap magnetorheological fluid (MRF) clutch connecting rotatable input and output members, and includes a drum connected to the output member and a rotor connected to the input member. The drum contains a magnetically-permeable stator and a magnetic core, while the rotor has a magnetically-permeable member extending axially into the drum to define an outer working gap in conjunction with the stator and an inner working gap in conjunction with the magnetic core. MR fluid fills the working gaps, and a magnetic field generator or electromagnet induces a magnetic field when electrical current is passed through a field coil therein to change an apparent viscosity of the MR fluid. The inner and outer working gaps have a predetermined inner to outer gap thickness ratio balancing the slip power dissipation per unit volume in each of the working gaps.
