Abstract
A vehicle includes a powertrain and an electric parking brake. A controller activates the electric parking brake in response to the powertrain transitioning to an off state that inhibits production of propulsive torque during an ignition cycle when a vehicle speed is less than a predetermined speed and in a presence of conditions that inhibit the powertrain from transitioning to an on state that permits production of propulsive torque.
