摘要： A clutch assembly with a clutch input, first and second clutch outputs, a first clutch pack between the clutch input and the first clutch output, and a second clutch pack between the clutch input and the second clutch output. A clutch spring is positioned in the clutch assembly to engage the first clutch pack so that rotary power is normally transmitted from the clutch input, through the first clutch pack to the first clutch output. Disengagement of the first clutch pack occurs automatically when the second clutch pack is engaged to transmit rotary power between the clutch input and the second clutch output.

摘要： A drive module includes a Ravigneaux gearset, first and second input shafts, shift member, and differential. The first planet gears of the gearset can engage the first sun gear and the second planet gears, which can engage the second sun gear. The first input shaft can rotate with the second sun gear and receives torque from a first motor. A first gear can be coupled to the carrier of the Ravigneaux gearset for rotation therewith and meshingly engages the differential input. The second input shaft receives torque from a second motor and is drivingly coupled to the differential input. When the shift member is in a first position, the shift member drivingly couples the first sun gear to a first differential output. When the shift member is in a second position, the shift member couples the first sun gear to a housing to prevent rotation of the first sun gear.

摘要： An electric drive module and a method for switching a drive module between a torque vectoring and at least one propulsion mode are provided. A controller can switch the drive module to the torque vectoring mode when a first set of conditions is met and can switch to one of the propulsion modes when either a second or a third set of conditions is met. The first set can include: torque requested by an operator is less than or equal to a first demand threshold; and a vehicle velocity is greater than or equal to a first velocity threshold. The second set can include: the vehicle velocity is less than a second velocity threshold; and a vehicle lateral instability is less than or equal to an instability threshold. The third set can include: the torque requested by the operator of the vehicle is greater than a second demand threshold.

摘要： The present disclosure relates to a method for controlling an application of regenerative brake torque to a plurality of wheels of at least one of a hybrid electric vehicle or an electric vehicle, to avoid brake instability. The method may involve sensing variables such as an angle of a steering wheel of the vehicle, a speed of the vehicle, a brake pedal rate as an operator engages a brake pedal, and a wheel slip of each of the front and rear wheels. A commanded lateral acceleration may be determined representing a steady state lateral acceleration that the vehicle would reach at an actual vehicle speed and with a presently sensed steering wheel angle. The application of regenerative brake torque can then be controlled based on the sensed wheel slips relative to at least one predetermined wheel slip limit. The predetermined wheel slip limit is determined based at least in part on the determined commanded lateral acceleration.

The planetary differential assembly is configured to provide a 50-50 torque split between the first and second output sun gears. The first axle shaft is coupled to the first output sun gear for rotation therewith. The second axle shaft is coupled to the second output sun gear for rotation therewith.

摘要： A park lock having an actuator assembly for pivoting a pawl relative to a dog ring. The actuator assembly has a first linear actuator, a locking mechanism, a first biasing spring and a second linear actuator. The first linear actuator has a first output member that is movable along a movement axis that is parallel to a pivot axis of the pawl. The locking mechanism is configured to selectively couple the first output member and a cam for common movement along the movement axis. The first biasing spring is configured to move the cam along the movement axis relative to the first output member when the locking mechanism decouples the cam from the first output member. The second linear actuator is configured to move the cam along the movement axis and against the first biasing spring when the cam is decoupled from the first output member.

摘要： A method is described for estimating longitudinal velocity of a vehicle on a road surface. The method includes obtaining a measured value of vehicle acceleration, which is dependent on longitudinal acceleration of the vehicle and vertical acceleration of the vehicle when a slope of the road surface is non-zero. The method includes determining an initial estimate of the slope. The method includes determining a difference between the initial estimate of the slope and a prior estimate of the slope and, based on the difference, setting a current estimate of the slope to be equal to the initial estimate or the prior estimate. The method includes estimating the longitudinal velocity of the vehicle based on the current estimate of the slope and the measured value of vehicle acceleration. The method includes controlling at least one wheel of the plurality of wheels based on the estimated longitudinal velocity of the vehicle.
