Control method for a drive system under drive-off conditions

Engine torque (MF) is set to match a driver's requirements or related value. When set, this torque/related value is reduced by a differential amount ( DELTA M) to preserve allowed engine torque (MV) or related value, which is set as a set point value, and a driving motor is triggered so as to release an engine torque in the range of the allowed engine torque. A clutch mechanism adjusts towards engagement.
