摘要： A system and method for controlling regenerative braking in a vehicle having an electric motor and a torque-converter clutch may include the step of implementing a regenerative-braking torque request based at least in part on a speed of the motor and a slip of the torque-converter clutch. A motor torque command based at least in part on a deceleration of the motor may be sent to and used to control the motor.

摘要： A system and method for estimating disconnect clutch torque during engine start with the motor in vehicles having an engine selectively coupled to the motor and transmission may be configured to control motor torque based on a clutch torque estimated from a difference in a measured powertrain state and a predicted powertrain state using motor torque as an input. The powertrain states may include, for example, motor speed, turbine speed, engine speed and clutch torque. An adaptive gain may be used to drive the difference between measured and estimated clutch torque toward zero.
