摘要： A vehicle includes a powertrain system and a friction braking system, the powertrain system including a hybrid transmission operative in one of a fixed gear operating range state and a continuously variable operating range state to transmit torque between an input member and a torque machine and an output member coupled to a driveline. A method for operating the vehicle includes monitoring operator inputs to an accelerator pedal and a brake pedal, monitoring vehicle speed, maintaining the transmission in a present operating range state subsequent to the operator disengaging the accelerator pedal absent the operator engaging the brake pedal, transitioning the transmission device to a continuously variable operating range state subsequent to the operator disengaging the accelerator pedal and the operator engaging the brake pedal, executing regenerative braking by controlling the torque machine to react torque through the transmission to brake the vehicle through the driveline when the operator engages the brake pedal and the speed of the vehicle is greater than a first threshold, and disabling the regenerative braking when the operator disengages the brake pedal and subsequently reengages the brake pedal when the speed of vehicle is less than a first threshold and greater less than a second threshold.

摘要： A control method for a hybrid powerplant includes receiving a pre-transition signal, and selectively adjusting a combustion torque of an engine of the powerplant between a first torque value and a second torque value prior to a deactivation transition period based on the pre-transition signal, wherein the second torque value is less than the first torque value. The method further includes selectively adjusting an electric drive torque of an electric machine of the powerplant prior to the deactivation transition period based on the pre-transition signal and the combustion torque. The selectively adjusting the electric drive torque includes adjusting the electric drive torque such that a sum of the combustion torque and the electric drive torque is equal to a desired drive torque of the powerplant during a pre-transition period prior to the deactivation transition period. A related control system is also provided.
