METHOD FOR CONTROLLING AN AUTOMATIC GEARBOX FOR A MOTOR VEHICLE

摘要

A method for controlling an automatic gearbox for a motor vehicle having at least two different drive train states The method comprises the following steps: determining the minimum deceleration force requirement that needs to be achieved by the drive train state depending on the speed of the vehicle, the longitudinal acceleration and the resistive forces experienced by the vehicle, then taking a decision in order to authorise 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.
