Abstract
A serial data communication system and protocol for communicating data on a serial data bus in a vehicle. The serial data communication system includes a serial data bus connected to a plurality of electronic devices in a vehicle. Each of the electronic devices includes an encoder for encoding bits of information and a decoder for receiving data and decoding the received serial data. The present invention provides for a communication protocol for communicating data on the serial data bus including the steps of providing serial data to be transmitted onto the serial data bus in the vehicle. The serial data is encoded with a pulse width varying as a function of a time, and the time-based variable pulse width is assigned to groupings of at least two data bits to code each of the data bit groupings. A series of coded data bit groupings are transmitted onto the serial data bus in the vehicle, and the electronic devices may receive and decode the encoded data signals to decipher the data.
