Abstract:
A vehicle-hold control method is used to hold an engine-powered vehicle from rolling backward on a road gradient during an engine start. The engine shuts down when the vehicle is stopped following operation of the vehicle under engine power. The engine is re-started during an engine cranking interval as vehicle wheel brakes are applied. The brakes are released in response to detection of pre-calibrated engine speed characteristics.
