Abstract

A method for controlling an automatic gearbox for a motor vehicle having at least two different drive train states. The method includes: determining minimum deceleration force requirement that needs to be achieved by the drive train state depending on speed of the vehicle, longitudinal acceleration, and resistive forces experienced by the vehicle, then taking a decision to authorize or prohibit the drive train state for which the minimum deceleration force requirement has been calculated depending on the deceleration force setpoint, the current drive chain state, and the minimum force achievable by the drive train state in question.
