摘要： A method to operate a clutch device in an electro-mechanical transmission mechanically-operatively coupled to an internal combustion engine and at least one electric machine includes, in response to a failure condition detected within a flow control device configured to facilitate flow of hydraulic fluid for operating the clutch device, selectively preventing the flow of hydraulic fluid from entering the flow control device and feeding the clutch device. Synchronization of the clutch device is initiated when the clutch device is intended for activation, and only if the clutch device is synchronized, the flow of hydraulic fluid is selectively permitted to enter the flow control device to activate the clutch device.

摘要： A method is provided to detect the presence of hydraulic line pressure in a hydraulic control system in an electromechanical transmission. The method includes determining an estimated hydraulic line pressure of the hydraulic control system based upon an input flow and an output flow of hydraulic fluid. The input flow and output flow are regulated with a pressure control device, which is energizable on operator demand. A pressure detection device is fluidly connected to the pressure control device to detect the presence of hydraulic pressure. An override module is applied to the estimated hydraulic line pressure to determine a corrected hydraulic line pressure. The override module sets the corrected hydraulic line pressure to predetermined values based on the operating state indicated by the pressure detection device. The override module corrects for an over-estimation of hydraulic line pressure in operating conditions such as low environmental temperatures.

摘要： A system includes a friction element having a driving mechanism and a driven mechanism. At least one of the driving mechanism and the driven mechanism is configured to rotate. A drive unit is configured to provide a torque to at least one of the driving mechanism and the driven mechanism. A control processor is configured to diagnose a friction element failure based on a slip speed, which is the difference between rotational speeds of the driving mechanism and the driven mechanism. The control processor is further configured to induce a slip condition as part of a shift process and diagnose the friction element failure if the derived slip speed is substantially zero after inducing the slip condition.

摘要： A vehicle includes a pump configured to output fluid at a commanded pressure when driven by a motor. A first hydraulic device is operably connected to the pump and configured to operate in response to receiving fluid at a first pressure. A second hydraulic device is operably connected to the pump and configured to execute a shift command in response to receiving fluid at a second pressure. A control processor is configured to control the commanded pressure in accordance with a priority scheme. That is, the control processor is configured to direct at least a portion of the commanded pressure from the first hydraulic device to the second hydraulic device for a duration of a shift command based on the priority scheme and redirect at least a portion of the commanded pressure to the first hydraulic device upon completion of the shift action.
