ABSTRACT:
In an electronic speed control circuit for automotive vehicles, a memory capacitor is connected at one end thereof to a speed signal generator and at the other end thereof to the gate of a field effect transistor to memorize a command speed signal. The electronic control circuit comprises a setting circuit for momentarily applying a constant voltage to a common junction between the gate of the field effect transistor and the memory capacitor. The setting circuit includes a second field effect transistor whose source is connected to a constant voltage circuit and whose drain is connected to the common junction between the memory capacitor and the first-named field effect transistor and a manual control circuit connected to the gate of the second field effect transistor to normally connect the gate of the second field effect transistor to the ground and to momentarily connect the constant voltage circuit to the gate of the second field effect transistor upon actuation of the manual control circuit.
