摘要： An automatic transmission includes a control system for controlling a clutch of the transmission. The control system includes a first variable flow solenoid and a second variable flow solenoid, each in selective fluid communication with the clutch. The first variable force solenoid provides hydraulic fluid within a first pressure range of 0 and 1,000 kPa. The second variable force solenoid provides hydraulic fluid within a second pressure range of 0 and 2,000 kPa. A transmission controller sends an electrical signal having a current between the range of 0 and 1 amp to one of the first and second variable flow solenoids. The pressure output of each of the first and second variable force solenoids is a function of, within their respective first and second pressure ranges, the amplitude of the current of the electrical signal to provide two distinct power gains to the single clutch.

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.

摘要： A method for controlling a clutch assembly includes controlling an actual clutch fill pressure using open-loop pressure controls when an active fill phase is detected, and using closed-loop pressure controls when the active fill phase is complete or when an overfill condition is detected. The method supplies the actual clutch pressure according to a second set of open-loop pressure controls when a step in commanded clutch pressure is detected. The method monitors a fill pressure and time during the step, and applies the clutch pressure according to the closed-loop pressure controls when either value equals a corresponding threshold value. A clutch assembly has a piston for compressing clutch disks to initiate a shift event, an algorithm for controlling the shift event, and a sensor for determining an actual clutch pressure during the shift phases. The algorithm switches between closed-loop and open-loop pressure controls in response to different shift phases.
摘要翻译：一种用于控制离合器组件的方法包括当检测到有效填充相位时使用开环压力控制来控制实际离合器填充压力，并且当主动填充阶段完成时或当检测到过度填充状态时使用闭环压力控制。当检测到指令离合器压力的阶跃时，该方法根据第二组开环压力控制提供实际的离合器压力。该方法监测步骤期间的填充压力和时间，并且当任一值等于相应的阈值时，根据闭环压力控制施加离合器压力。离合器组件具有用于压缩离合器盘以启动换档事件的活塞，用于控制换档事件的算法，以及用于在换档阶段期间确定实际离合器压力的传感器。该算法响应于不同的换档阶段在闭环和开环压力控制之间切换。
