METHOD AND APPARATUS TO OFFLOAD OFFGOING CLUTCH TORQUE WITH ASYNCHRONOUS ONCOMING CLUTCH TORQUE, ENGINE AND MOTOR TORQUE FOR A HYBRID POWERTRAIN SYSTEM |
摘要 |
A powertrain includes an electromechanical transmission mechanically-operatively coupled to an internal combustion engine and an electric machine adapted to selectively transmit mechanical power to an output member. A method for controlling the powertrain includes commanding a shift from a first operating range state to a second operating range state, identifying an off-going clutch, controlling torque output from said electric machine to offload reactive torque transmitted through said off-going clutch, selectively applying an oncoming clutch to offload reactive torque transmitted through said off-going clutch, and reducing a clutch torque capacity of said off-going clutch when said reactive torque transmitted through said off-going clutch is substantially zero.
