ABSTRACT:
The invention concerns a method for propulsion regulation of an automobile in the sense of prevention of undesirable spinning of the driven vehicle wheels whereby, as needed, only one of the wheel brakes is activated or the engine torque is reduced. Thereby is determined in the manner of an adaptive regulation in constant repetition from measured rotational speeds and stored vehicle and engine parameters for each driven wheel according to the relation M.sub.u =.theta.*..DELTA..omega., the excess moment causing the spinning of the wheel concerned and subsequently for each of the driven wheels in accordance with the relation M.sub.red =M.sub.u +k(.DELTA..omega.-s) the reduction moment required to eliminate the spinning/tendency to spin, which reduction moment is caused to be applied, depending on each driving situation, either in form of a brake torque in the correct magnitude and/or in form of a reduction of the engine torque in the correct magnitude.
