    摘要: An electric drive module (EDM) configured to generate and transfer drive torque to a driveline for propulsion of an electric vehicle. The EDM includes a gearbox assembly, an electric motor having a rotor and a stator, and a thermal management system. The thermal management system includes a fluid circuit configured to supply a fluid to the gearbox assembly, the rotor, and the stator, and a pump configured to direct the fluid through the fluid circuit. A valve is disposed on the fluid circuit and configured to selectively move between (i) a closed position where the fluid is not supplied to the stator, and (ii) an open position where the fluid is supplied to the stator for cooling thereof.

    摘要: A system for providing pressurized hydraulic fluid includes an engine driven main pump and an electrical motor driven auxiliary pump. The auxiliary pump provides hydraulic fluid at line pressure to shift control subsystems during a vehicle launch while the main pump provides hydraulic fluid to cooler or lubrication subsystems during the vehicle launch. A pressure regulation valve regulates the pressure of the hydraulic fluid from the main pump. Once the main pump reaches a critical speed, the main pump provides hydraulic fluid at line pressure to the hydraulic control system and the auxiliary pump is turned off.

    摘要: An electro-hydraulic park control system includes a park piston and a park control valve disposed in a valve body of a transmission of a vehicle and configured to control a supply of hydraulic fluid pressure to control the park piston and to operate such that (i) no single element failure of the transmission will cause the transmission to shift from a park state to a non-park state or (ii) to shift from a drive, reverse, or neutral state to the park state, (iii) the transmission is able to remain in the non-park state and remain in or transition to the neutral state when a controller of the transmission is malfunctioning while the transmission is operating in the drive, reverse, and neutral states, and (iv) the transmission is able to quickly transition to the park state while an engine/motor driven pump of the transmission is off or not running.

    摘要: In a multiple mode continuously variable transmission having a variator, a planetary gear assembly, a low mode brake that grounds a first component of the planetary gear assembly to provide lower operating speeds and a high mode brake that grounds a second component of the planetary gear assembly to provide higher operating speeds, the method of providing a mode upshift comprising the steps of adjusting the ratio of the variator from a low ratio to a high ratio, releasing the low mode brake while simultaneously engaging the high mode brake during a torque phase of the shift and reducing the variator ratio from a high ratio to a low ratio during the inertia phase of the shift, thereby eliminating torque interruption and providing a constant torque output.

    摘要: A stepper motor assembly includes a unipolar winding stepper motor, four drivers, and a transmission control module. The stepper motor has four coil parts. Each driver has a transistor connected to one of the coil parts. Each driver is operable to drive a phase of the stepper motor, where first and second phases are opposites of each other and third and fourth phases are opposites of each other. The transmission control module houses the four transistors. A transmission is also disclosed that includes the disclosed stepper motor assembly.

    摘要: A variable flow orifice for a hydraulic control system in a transmission includes a shape memory alloy that selectively increases and decreases the size of an orifice. The deformation of the shape memory alloy, and therefore the size of the orifice, is a function of the temperature of the transmission. During cold conditions the orifice size is increased and during normal operating conditions the size of the orifice is decreased.
