Device for reducing longitudinal dynamic instabilities of vehicles
First Claim
1. In a system for reducing longitudinal dynamic instabilities of vehicles, in particular back and forth movements of cargo and uncontrolled repetitive application of fuel, the system having means for adjusting the deflection of a setting device for the fuel-air mixture which is to be fed to an internal combustion engine of the vehicle, the improvement wherein said system further comprises:
- means responsive to the rotational speed of the engine for providing an electric signal; and
whereinsaid deflection adjusting means comprises differentiation means for differentiating said electric signal of the engine rotational speed and a limiter-amplifier which is connected to the output of said differentiation means, said adjusting means providing a deflection of the setting device in response to an output signal of said limiter-amplifier.

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.
