Abstract
A method is proposed for the control and regulation of a drive system of a motor vehicle having one electronic transmission control for an automatic transmission and connected therewith an electronic engine control for a prime mover. In a coasting operation of the drive system, during a change over of a transmission element from an open to a closed or a slipping state during a coupling procedure of the transmission or a regulation procedure of the transmission element, rotatory masses of the engine are regulated and accelerated under control so that a vehicle deceleration is less than a presettable tolerance value.
