    摘要： A method and apparatus to control an electro-mechanical transmission during a shift event, including identifying a fault in an off-going clutch, is provided. The method includes deactivating an off-going torque-transfer clutch, monitoring slippage of the off-going torque-transfer clutch, and limiting a change in operation of an electrical machine operatively connected to the transmission until the slippage of the off-going torque-transfer clutch exceeds a threshold. Limiting a change in operation of the electrical machine comprises limiting an output torque of the electrical machine, comprising limiting a time-rate change in the output torque and limiting a magnitude of the output torque. The limit of the change is discontinued when the slippage of the off-going torque-transfer clutch exceeds the threshold.

    摘要： A method of regulating operation of a hybrid transmission in a vehicle includes determining a desired transmission state using a first module, generating transmission control signals based on the desired transmission state using a second module and receiving at least one transmission parameter signal at the second module. An actual transmission state is determined based on the at least one transmission parameter signal at the second module. Whether a fault is present within the hybrid transmission control system is determined based on the desired transmission state and the actual transmission state at the first control module.

    摘要： An electrically variable transmission (EVT) selectively establishes various EVT modes and a neutral mode. The EVT includes a source of pressurized fluid, fluid-actuated clutches, various solenoid-actuated valves including trim valves and blocking valves adapted to control a flow of pressurized fluid to the clutches to establish the transmission operating modes, and an electronic control unit (ECU). The ECU actuates different combinations of the solenoid-actuated valves to establish the different transmission modes. The solenoid-actuated valves are configured in such a manner as to provide the EVT with one or more default operating modes in the event the ECU temporarily loses electrical power. Depending on the particular configuration, the default modes can be the neutral mode alone, or the neutral mode combined with one or more of the EVT modes, with the EVT modes enabled by providing one or both of the blocking valves with a latching feature.
