Title:
DIGITAL TRANSMISSION AND CONTROL SYSTEM FOR VEHICLES
Document Type and Number:
WIPO Patent Application WO2003015331
Kind Code:
A3
Abstract:
A digital transmission system for replacing complex, many-wire, analog system in vehicles includes a signal bus 1 and optional power bus 4. Uni-directional or bi-directional signal tap lines 2 attach to the signal bus with terminal devices. The signal bus and tap lines terminate in microprocessor devices 3a, 3b, 3c that generate, prioritize, send, receive, and process signals sent through the signal bus and its tap lines. Electro-mechanical, electrical, and electronic devices attach directly or through converters 6a, 6b to the terminating microprocessors. When any terminal device 7a, 7b, 7c, 7d, 7e, 7f generates information, the attached microprocessor generates a signal identifying the device and prioritizing and coding the information generated. The microprocessor then passes this signal to the signal bus and its tap lines. All microprocessors receive and decode the signal, determine its priority, and pass information in the signal to the correct devices in the proper form.
