Abstract
A method and apparatus is used in a motor vehicle to serially communicate data between two or more communication nodes coupled to a data bus. Each communication node receives and transmits information on the data bus. Signals representative of operation of the vehicle are received directly by nodes and encoded for transmission to one or more other nodes via the data bus. The signals, which may for example originally be in parallel format, are encoded into serial digital data for data bus transmission. Each bit of the serial digital data is formatted into subbits of unequal duration. A designated module then receives and decodes the serial digital data for information or control purposes. Preferably the subbits progressively increase in duration with one working embodiment having three subbits of seven (7), eight (8) and nine (9) microseconds, respectively, to define a bit time of twenty four (24) microseconds.
