    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: 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: Slip across a torque converter of an automotive powertrain is estimated using powertrain operating parameters throughout a powertrain operating cycle for use in powertrain control and diagnostic operations. Slip across the torque converter is estimated and is periodically updated in accordance with an adaptive control procedure to maintain model accuracy over time. The slip is estimated for both torque converter coupling and torque multiplication scenarios, with the greater of the estimates identified as indicating current slip. Current slip is applied to generate actual transmission gear ratio which is compared to commanded gear ratio when a transmission shift maneuver is not in process to identify transmission solenoid fault conditions, and which is applied for precise transmission shift enhancement control during a transmission shift maneuver.
