摘要： The present disclosure relates to a vehicle (1) having a torque generating machine (4); and one or more driven wheel (WD). A driveline (6) is provided for transmitting torque from the torque generating machine (4) to said one or more driven wheel. The driveline (6) includes a torque transmitting means (8). A first decoupling mechanism (11) is operable to decouple the torque transmitting means (8) from the torque generating machine (4). The first decoupling mechanism (11) is closed to couple the torque transmitting means (8) to the torque generating machine (4) and is opened to decouple the torque transmitting means (8) from the torque generating machine (4). A second decoupling mechanism (12) is operable to decouple the torque transmitting means (8) from the one or more driven wheel. The second decoupling mechanism (12) is closed to couple the torque transmitting means (8) to the one or more driven wheel and is opened to decouple the torque transmitting means (8) from the one or more driven wheel. A controller (2) is provided having at least one electronic processor for controlling operation of the first and second decoupling mechanisms (11, 12). The at least one electronic processor (P) being configured to determine a target operating speed of the torque generating machine (4), control the operating speed of the torque generating machine (4) in dependence on the determined target operating speed, close the first decoupling mechanism (11) when the operating speed of the torque generating machine (4) at least substantially matches the determined target operating speed and close the second decoupling mechanism (12) after closing the first decoupling mechanism (11). The present disclosure relates to a corresponding method of controlling first and second decoupling mechanisms (11, 12) to control the transmittal of torque from a torque generating machine (4) to one or more driven wheel of a vehicle (1).

摘要： A system and method are provided for hybrid electric internal combustion engine applications in which a motor-generator, a narrow switchable coupling and a torque transfer unit therebetween are arranged and positioned in the constrained environment at the front of an engine in applications such as commercial vehicles, off-road vehicles and stationary engine installations. The motor-generator is preferably positioned laterally offset from the switchable coupling, which is co-axially-arranged with the front end of the engine crankshaft. The switchable coupling is an integrated unit in which a crankshaft vibration damper, an engine accessory drive pulley and a disengageable clutch overlap such that the axial depth of the clutch-pulley-damper unit is nearly the same as a conventional belt drive pulley and engine damper. The front end motor-generator system includes an electrical energy store that receives electrical energy generated by the motor-generator when the coupling is engaged. When the coupling is disengaged, the motor-generator may drive the pulley portion of the clutch-pulley-damper to drive the engine accessories using energy returned from the energy store, independent of the engine crankshaft.

摘要： A control device mounted on a four-wheel drive vehicle includes: a slip ratio calculating unit that obtains a slip ratio of main driving wheels based at least on wheel speeds; a smoothing unit that smooths the slip ratio by filtering; and a driving force control unit that controls a driving force transmission device so that a driving force that is transmitted to auxiliary driving wheels increases as the slip ratio smoothed by the smoothing unit increases. The smoothing unit uses a larger time constant for the filtering when a vehicle speed is less than a predetermined value than when the vehicle speed is equal to or higher than the predetermined value

摘要： The present invention provides improved, real time sensing of pressure supplied to the hydraulic operator of a clutch for a motor vehicle driveline power take off. A proportional sensor in the hydraulic line to the power take off clutch actuator provides a data signal in real time of the actual pressure applied to the clutch actuator. This signal is provided to the power take off control module (PCM) and/or to the transmission control module (TCM). The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.

摘要： A clutch control device is provided for a 4-wheel drive vehicle. The clutch control device includes a 4WD control unit that controls the engagement and release of a friction clutch and a dog clutch which are arranged separately in the two paths. The 4WD control unit has a synchronization speed control unit, and at a time of transition from a disconnected, two-wheel drive mode, in which the friction clutch and the dog clutch are released, to a connected, four-wheel drive mode, in which the friction clutch and the dog clutch are engaged, the synchronization speed control unit reduces a synchronization speed of the dog clutch more during vehicle deceleration than when the vehicle is not decelerating.

摘要： A clutch assembly configured to selectively engage and disengage a power source and a transmission includes an input member configured for coupling to the power source and an output member configured for coupling to the transmission. A clutch pack is engaged with the input member for co-rotation about an axis. A housing is engaged with the output member and with the clutch pack and is further configured to move in a first direction along the axis and in a second direction opposite to the first direction. The clutch assembly includes a cover and a ring member positioned along the axis from the cover such that the cover and the ring member define a movable chamber therebetween configured to receive a hydraulic fluid. The clutch pack is operable to decouple the input member from the output member in response to a pressure of the hydraulic fluid within the chamber.
