Abstract
The invention relates to a motor vehicle comprising a fully automatic transmission, of the type in which a management unit (20) controls the operation of the engine (10) as a function of torque demand information from a throttle pedal (24), and of the type in which the engine management can be modified as a function of information transmitted by a transmission (16) control unit (22) to the engine (10) management unit (20), characterized in that for certain phases of operation of the vehicle, the transmission (16) control unit (22) inhibits the action of the torque demand information, for which it substitutes an engine management command to which the management unit (20) is subordinated.
