A throttle regulator for the throttle of a combustion engine of an automotive vehicle for controlling the traction slip or the speed. The throttle regulator comprises two devices influencing the position of the throttle in an adding manner. The first device is operated by the driver such as by means of a pedal, and the second device is a servomotor operated on the basis of an electronically formed signal, with the basic position of the second device corresponding to a mid-position wherein the position of the throttle is influenceable both in the closing and in the opening directions. A first signal is electrically provided which corresponds to the throttle position. The first signal is compared to a reference signal provided by control electronics and an output signal is applied to the servomotor until the first signal and the reference signal conform to one another.
