ABSTRACT:
An apparatus for controlling the traveling speed of a motor vehicle with an electrical control unit acted upon by a speed dependent signal, which unit compares the then present actual speed with a desired speed fed into a storage memory unit, and upon a deviation of the actual speed from the desired speed, a deviation signal dependent on the magnitude of the deviation is transmitted to a control stage, the latter influencing the ratio of the fuel-air mixture which is fed to the vehicle motor, as well as a manual operatively switchable circuit for acceleration of the vehicle to the desired driving speed stored in the storage memory unit. A differentiating stage is provided an input which is fed with the speed dependent signal. The output signal of the differentiating unit influences the deviation signal directly or indirectly in the sense of a decrease (compared to a deviation signal were the differentiating unit absent). Means for the additional time dependent variation of the output signal of the differentiating unit are provided of such type that with increasing time from the moment of turning on the manually operative switchable circuit, the output signal of the differentiating unit changes in the sense of increasing the acceleration.
