PURPOSE:To eliminate any influence of a road surface or the like as well as to control a body vibration, by controlling an engine so as to make it come within the rotational variation limit value that is obtained in converting the acceleration variation limit value by a converting device having the conversion value where the engine rotational variation measured by a rotational variation measuring device is learned and created. CONSTITUTION:A difference between the body acceleration variation converted by a conversion device 102 of the engine speed variation measured by a rotational variation measuring device 100 and another body acceleration variation measured by an acceleration variation measuring device 101 is detected by a difference detecting device 104. And, the converted value of the conversion device 102 is altered by an altering device 106 on the basis of output of the difference detecting device 104. And, when a different quantity is more than the specified value, control over the altering device 106 is stopped by a stopping device 103, and it is not adopted as value for learning. An engine controlling device 105 sets the engine rotational variation measured by the rotational variation measuring device 100 to a range within the rotational variation limit value obtained in converting the acceleration variation limit value by the altering device 102 having the converted value learned and created like this.
