Abstract
Abstract A remotely controlled automobile engine starting control system which includes a radio transmitter remotely located from a radio receiver and the control circuit, the actuation of the control circuit from the transmitter initiating the timing of two preselected periods, the first of which controls the actuation of the automobile ignition and engine cranking systems until such time as the engine is started and the second of which controlling the period which the engine will run after actuation of the radio transmitter. The system further includes various safety features to preclude theft of the automobile as a result of the engine running and a system for initiating the energization of the accessory circuitry to permit energization of, for example, the air conditioning or heating system.
