ABSTRACT:
A servo control system is used to supply a command position signal to control the throttle opening of the engine, and hence vehicle speed. To permit increase of amplification without instability of the positioning control loop when sensing throttle position and feedback of the throttle position error signal, the feedback signal is degressively nonlinearly related to absolute throttle position in order to match the nonlinear throttle position-torque characteristics of automotive type internal combustion engines. The non-linear relation is obtained with a minimum of external connections by connecting a resistor to a source of fixed supply which is connected to the slider of a potentiometer having one terminal unconnected and the other terminal connected to ground or chassis. Only two supply lines to the throttle positioning sensor are needed, namely one for the resistor to a source of supply and the other for the variable resistor take off from the slider.
