Abstract
A method for controlling a vehicle power train that includes a heat engine connected to the transmission of the vehicle by a clutch controlled between an open position and a closed position of the transmission by a computer of the transmission exchanging information with a computer of the heat engine. The method includes sending, in order to shut down the engine before the clutch is opened when the vehicle is in motion, the kinematic chain being closed and the injection interrupted, a message from the computer of the transmission to the computer of the engine at a first moment in time so as to synchronize an opening of the clutch and the closure of an air flap of the engine at a second moment in time subsequent to the first moment.
