摘要： A transmission includes four planetary gearsets and five torque transmitting devices operative to provide eight forward speed ratios. At least one of the torque transmitting devices is engaged during two different speed ratios. The torque transmitting device includes a piston partially defining two separate and independently pressurizable chambers. Accordingly, the transmission enables both chambers to be pressurized for speed ratios in which a high torque capacity is required of the torque transmitting device, and only one of the chambers to be pressurized for speed ratios in which a low torque capacity is required of the torque transmitting device.

摘要： The present invention provides a clutch having two pistons, a first piston defining a first, smaller area and a second piston, defining a second, larger area. The separate pistons are independently provided with flows of pressurized hydraulic fluid from first and second independent modulatable control valves. Engagement of the clutch may be rapid by providing hydraulic fluid to the smaller area piston, provide greater engagement force by providing hydraulic fluid to the larger area piston or a combination of speed and force by utilizing modulated or unmodulated flows of hydraulic fluid to both pistons.

摘要： A pressure control apparatus is disposed in a pressure control system for a transmission to set pressure control at a torque-transmitting mechanism. The pressure control apparatus includes a torque-transmitting mechanism control valve, which distributes pressure from a high pressure source to the torque-transmitting mechanism. Also within the pressure control apparatus is a boost valve mechanism, which is effective to control feedback pressure on the torque transmitting mechanism pressure regulator valve thereby controlling the pressure rise at the torque-transmitting mechanism and also permitting a boost pressure to be distributed to the torque-transmitting mechanism when full engagement thereof is required.

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： A vehicle includes an engine, transmission, and controller. The transmission includes a clutch pack, a clutch piston, and a position sensor. The sensor measures a changing magnetic field with respect to the piston, and encodes the measured magnetic field as a raw position signal. The controller receives the raw position signal and processes the raw position signal through a signal processing module to generate a filtered signal attenuating signal noise in the position signal. The controller determines a commanded position of the piston, and calculates separate proportional (P), derivative (D), and integral (I) control terms using the commanded position and filtered position signal. The controller also calculates a feed-forward control term using the commanded position, and a required flow rate for actuating the clutch pack as a function of the PID terms and the feed-forward commanded position term. The controller actuates the clutch pack using the commanded flow rate.
