ABSTRACT:
A device for reducing longitudinal dynamic instabilities of vehicles, in particular back and forth movements of cargo (load) and the uncontrolled periodic feeding of gas having, for the purpose of damping, a differentiation device (8) which differentiates an electric signal of the engine speed of rotation, preferably a voltage. The output signal of the differentiation device feeds a limiter-amplifier (9), the output signal of which, in its turn, intervenes in the deflection of a setting device (4) which acts on the fuel-air mixture of the engine. With this device, a deflection of the setting device takes place which counteracts periodic disturbing changes in speed of rotation while, upon an intended change in position of the setting device by the gas pedal, no perceptible additional effect is exerted on the setting member.
