Einrichtung, insbesondere in Fahrzeugen, zur leitungsgebundenen, bidirektionalen Übertragung von elektrischen Signalen

摘要

The bidirectional signal transmission system for use in road vehicles has a primary side module (10) that connects with a secondary side module (30) via a transmission stage (20). A user switch (5) provides an input that is transmitted to control a load (31) and sensor signals operate a stage (31) to provide feedback to the primary side controller (11). The process may be a seat adjustment control operation. The primary side contains a power driver stage (13) that provides the necessary change from dc to ac voltage. Built into the secondary side is a time control circuit (38) that determines when the sensor is read.
