ABSTRACT:
A modulated vehicle cruise control system includes a source of vacuum, a servo transducer or control unit connected to the source of vacuum, an engine throttle position servo connected to the servo, a speed sensor and a logic circuit or command module. A modulator is disposed in series with and between the control unit and the source of vacuum. The modulator limits opening movement of the engine throttle by modulating communication of vacuum to the servo to prevent inefficient engine operation.
