    摘要: A method for providing an active engine stop of the engine of a hybrid electric vehicle. The method utilizes the electric machine to oppose the and rapidly stop the rotation of the engine at a controlled rate. The method includes the calculation of an input speed reduction trajectory using the engine speed when the active engine stop request is made and a predetermined speed reduction interval. The predetermined speed reduction interval is preferably less than a time from the active stop request to the shutoff command to the electric machine. The method provides rapid deceleration of the engine, particularly through the powertrain resonance speed, thereby reducing the amount of vibration energy dissipated through the powertrain and vehicle chassis. The method also removes the electric machine torques from the engine prior to achieving zero engine speed in order to avoid imparting a negative engine speed or counter-rotation of the engine. The method preferably comprises a complementary series of software control functions that allow the vehicle to actively stop the engine.

    摘要: An electromechanical transmission includes a rotor supported by a rotor hub that has at least one passage formed therein for providing cooling fluid flow to the rotor. Preferably, cooling fluid is provided to the passage through an orifice to control flow rate. An inner diameter of the rotor is supported by the rotor hub and fluid is pooled by the rotor hub opposite the rotor inner diameter for cooling thereof. Preferably, fluid is thrown by centrifugal force from the rotor hub onto rotor ends and then onto an inner diameter side of stator windings of a stator surrounding the rotor. A method of cooling an electromechanical transmission is also provided.

    摘要: Alternative methods of constructing a vertically offset structure are disclosed. An embodiment includes forming a flexible layer having first and second end portions, an intermediate portion coupling the first and second portions, and upper and lower surfaces. The distance between the upper and lower surfaces at the intermediate portion is less than the distance between the upper and lower surfaces at the first and second end portions. The first end portion is bonded to a base member. The second end portion of the flexible layer is deflected until the second end portion contacts the base member. The second end portion is bonded to the base member.
