Abstract
Abstract The disclosure describes an electrical control system for controlling essentially every function of a vehicle. In a preferred embodiment, the invention comprises a single harness formed of an electrical signal transmission path and an electrical power transmission path connected to a source of electrical power, control means for applying coded control signals to the electrical signal transmission path, and receiving means connected to the electrical signal and power transmission paths for receiving said coded electrical signals to selectively activate electrical switching means to operate desired load devices for performing selected vehicle functions.

Claim 1
Independent Claim
315 words
In a system for controlling substantially all electrical components of a self-propelled vehicle comprising a source of electrical power, improved apparatus comprising: a harness comprising an electrical power transmission path connected to said source of electrical power, a timing signal transmission path, and an information signal transmission path; means for generating a series of time-spaced clock pulses having a predetermined polarity that define counting states which occur in cycles; means for conducting said clock pulses on said timing signal transmission path; means for receiving each of said clock pulses and for generating a first series of information pulses having said predetermined polArity, each of said information pulses occurring during a predetermined one of said counting states in each cycle; means for transmitting said first series of information pulses over said information signal transmission path; counting means connected to said information signal transmission path for counting information pulses, means for generating a first output signal in response to the counting of the first series of information pulses; means for operating a first one of said components in response to said first output signal; means for receiving each of said clock pulses and for generating a second series of information pulses having said predetermined polarity, each of said second series of information pulses occurring during another predetermined one of said counting states in each cycle; means for transmitting said second series of information pulses over said information signal transmission path; means for generating a second output signal in response to the counting of the second series of information pulses; means for operating a second one of said components in response to said second output signal; means for generating and transmitting over said information signal transmission path reset pulses having said predetermined polarity which are coincident with two consecutive clock pulses; and means for detecting said reset pulses and for generating a signal which resets said counting means.

Claim 3
Dependent Claim
68 words
Apparatus, as claimed in claim 1, wherein the means for detecting comprises: first flip-flop means for producing one predetermined output state in response to a first reset pulse; gate means for producing an output pulse in response to the one predetermined output state and a reset pulse; and second flip-flop means for producing a second predetermined output state in response to said output pulse from the gate means.
Claim 4
Dependent Claim
89 words
Apparatus, as claimed in claim 2, and further comprising apparatus for terminating the generating of the first output signal by the means for generating, said apparatus comprising: third flip-flop means for producing one predetermined output state in response to the second predetermined output state; second gate means for producing a second output pulse in response to the one predetermined output state of the second flip-flop means and the second predetermined output state; and fourth flip-flop means for terminating the first output signal in response to the second output pulse.
