Device for the control of the traveling speed of a motor vehicle

In a device for the control of the traveling speed of a motor vehicle with a gas pedal actuatable by the vehicle driver, the gas pedal producing an electrical signal emitted to the desired value input of an electrical controller, the output signal of which acts on a positioning actuator, the latter being coupled with an element, particularly the throttle valve of the engine of the vehicle, which influences the fuel-air mixture, the instantaneous setting position of the positioning actuator being transmitted as an electric signal to the actual value input of the electrical controller, the improvement comprising

• circuit means for driving one of the inputs of the electrical controller,
• said circuit means for producing a signal for operatively influencing the position of the throttle valve, said latter-mentioned signal is dependent on at least one factor to be monitored,
• said circuit means contains, a control stage, said control stage has
• a desired value input, an actual value input, and an output,
• said output of said control stage is connected with the desired value input of the electrical controller and said desired value input of said control stage is fed with the electrical signal produced by said gas pedal, said actual value input of said control stage is applied with said signal which is dependent on the at least one factor to be monitored, and
• switches means for switching on and switching off, respectively, said circuit means, said switch means is actuatable by complete pivoting of said gas pedal.
