Abstract
A vehicle system for a hybrid electric vehicle that implements a transmission clutch support mode during a stop of the vehicle includes a hybrid powertrain, a brake system, a clutch and a controller. The hybrid powertrain includes an internal combustion engine and an electric motor that provides motor torque to a driveline for propelling the vehicle. The brake system selectively provides brake torque to drive wheels based on application of a brake pedal. The clutch opens and closes to engage the powertrain with the driveline. The controller initiates clutch support mode and determines whether a brake pedal release has been detected; commands a brake hold that maintains brake pressure of the brake system subsequent to detection of the brake pedal release; and commands the clutch to move to an engaged position while cancelling the brake hold resulting in concurrent blend-out of the brake torque and blend-in of the motor torque.
