  • Systems and methods for managing torque
    Patent number: 10112613
    Abstract: A method of managing torque at a vehicle standstill includes outputting torque from a powertrain to satisfy a driver torque demand. The method also includes, in response to a nonzero torque demand resulting in vehicle standstill, applying a friction brake to maintain the vehicle standstill and substantially reducing output torque of the powertrain during friction brake application. The method further includes satisfying driver torque demand using the powertrain and releasing the friction brake in response to the driver torque demand deviating from the nonzero torque demand by more than a predetermined amount.
    Type: Grant
