Abstract

An automatic starting system for the internal combustion engine of a vehicle includes a settable clock device in parallel with a remote control receiver, a plurality of relays and timed, thermal switches, a thermal switch flasher and a solenoid coupled to the throttle-gas pedal linkage of the vehicle. The relays and timed, thermal switches are arranged to couple current from the battery of the vehicle to the starter and to provide a variety of circuit paths depending upon the particular conditions existing within the vehicle. The flasher alternately energizes and deenergizes the solenoid which is mechanically coupled to pump the gas pedal when the engine is cold, before the time that battery current is coupled to the starter. A number of safety features such as a hood safety switch, an overspeed switch, a temperature switch and a low oil pressure switch, are provided in order to prevent damage to the vehicle and to prevent injury to others.

Claims
