Claim Text:
1. A method of controlling a vehicle with a hybrid powertrain having an engine with a rotatable crankshaft, a drive axle operatively connected to and driven by the crankshaft, and an electric motor/generator operatively connected to the crankshaft, the method comprising: monitoring, via an electronic controller, engine torque in a first direction of rotation and braking torque in an opposite second direction of rotation; monitoring, via the electronic controller, vehicle deceleration rate; monitoring, via the electronic controller, vehicle speed; controlling, via the electronic controller, the motor/generator to stop rotation of the crankshaft when the vehicle speed is non-zero if a percentage braking torque is greater than a predetermined percentage braking torque and the vehicle deceleration rate is greater than a predetermined threshold vehicle deceleration rate; and wherein the percentage braking torque is based on the monitored braking torque and the engine torque.
