According to the present invention, the improved apparatus provides a feedback control system for regulating an explosive-mixture forming device of a vehicle having an engine, accelerator pedal means for controlling the speed of the engine, a drive train including a drive shaft, a flywheel on the drive shaft, a gearbox having a plurality of gear stages, and a wheel assembly including at least one driven wheel. The apparatus includes first sensor means for detecting deflection of the accelerator pedal means, second sensor means for detecting the angular velocity of the drive shaft flywheel, third sensor means for detecting the torque of the drive shaft, fourth sensor means for detecting the angular velocity of the at least one driven wheel of the wheel assembly, and fifth sensor means for detecting the identity of the gear stage in use in the gearbox. The apparatus further includes feedback control means for attenuating vibration in the vehicle drive train, the feedback control means including data processing means for interpreting the parameters detected by the first, second, third, fourth, and fifth sensor means to monitor torsional vibrations in the drive train, and regulator means for controlling the explosive-mixture forming device to vary the quantity of explosive-mixture formed to vary thereby the torque of the engine so that vibration due to torsional rigidity of the drive train is lessened substantially.
