Abstract
A vehicle powertrain with engine start-stop characteristics is capable of maintaining a vehicle stationary on a roadway with a gradient when wheel brakes are applied to stop the vehicle as the engine is shut down. Vehicle creep and vehicle launch is achieved as the engine is re-started following detection of a brake release signal based on engine speed.
