An encoded electrical control systems for motor vehicle employs an encoder/transmitter that provides an encoded signal and a receiver/decoder which effectuates control of an associated device only upon receipt of a signal containing the code unique to that specific receiver/decoder. For motor vehicle applications, a secure ignition system is acheived by enclosing the encoder/transmitter in a tamperproof housing associated with the ignition switch assembly. The encoded signal is transmitted when the ignition switch is closed. The receiver/decoder is contained in another tamperproof housing adjacent an ignition system component essential to engine operation, and, only upon receipt of the unique, encoded signal from the transmitter, effectuates a necessary electrical connection to this ignition system component. Operation also may be initiated by an electronic lock in place of the conventional ignition switch.

A secure ignition system for a motor vehicle having an ignition switch and having an ignition system electrical component essential for engine operation, said system comprising: an encoder/transmitter for transmitting a unique, digitally encoded signal in response to actuation of said ignition switch, a first tamperproof housing enclosing at least part of said ignition switch, said encoder/transmitter and the interconnections therebetween, to prevent tampered actuation of said encoder/transmitter, receiver/decoder means, receiving the digitally encoded signal from said encoder/transmitter, for effectuating a necessary electrical connection to said essential electrical component in response to receipt only of said unique, encoded signal, another tamperproof housing enclosing at least part of said essential electrical component, said receiver/decoder means and the interconnections therebetween, to prevent tampered effectuation of said necessary electrical connection, together with another like encoder/transmitter and receiver/decoder means, said other encoder/transmitter transmitting a different unique, encoded signal in response to actuation of said ignition switch to the “engine start”position, and wherein said other receiver/decoder actuates the starter of said motor vehicle in response to reception only of said different encoded signal.
