occur which has a detrimental influence upon comfort and transmission life in order to counteract such oscillating shifts it is possible to proceed as shown in fig4 the electronic control device routinely determines in step 80 the position u03b1 of the throttle valve the motor vehicle speed v f and the actual transmission ratio i actual of the transmission or the variable speed unit in step 92 the system examines whether the actual transmission ratio differs from the transmission ratio shift range i u by less than a limit value if that is the case then in step 94 the system examines whether the change with respect to time d u03b1 dt of the accelerator pedal position u03b1 is above an accelerator pedal threshold value ps if that is the case then in step 96 the accelerator pedal value is held constant for a predetermined time the target rotational speed of the motor n target is subsequently calculated in step 98 then in step 100 the target transmission ratio i target of the transmission is calculated on the basis of the motor vehicle speed and the target rotational speed of the engine in step 102 the transmission ratio is changed in the direction i target or is adjusted to i target the system thereafter returns to step 90 if it is established in step 92 that the actual transmission ratio is different by a larger amount than limit value gw from the transmission ratio shift range the system immediately jumps to step 98 if it is established.
