Optical signal transmission system for an automotive vehicle

摘要

An optical signal transmission system for an automotive vehicle by which a number of electric signals generated from switches arranged on the steering wheel are transferred to other controllers optically and digitally for control the necessary vehicle operating conditions with high reliability, without producing electrical noise even while steering wheel is being turned. The optical signal transmission system of the present invention comprises optical transmission devices including an electricity-to-light converting means, a light-transmitting ring, a light-to-electricity converting means, in addition to a digital circuit including an encoder, decoder, etc.
