Abstract
In a method of preventing vibration noise in change-speed gearboxes, in particular of motor vehicles, with an electronic control of the ignition and the fuel measuring control of the internal combustion engine which is variable timewise as a function of events, the internal combustion engine is controlled as a function of the occurrence of gearbox vibration noise in order to change the combustion process of the said internal combustion engine so that no irregularities occur in the rotational vibration behavior.
