Matching circuitry adapting electric control devices for vehicle accessories - translates signals between vehicle transmission system and control devices using microcomputer under control of external interface

摘要

The circuitry adapts electric/electronic control devices for motor vehicle peripheral devices (1), such as an independent heater, a sun roof, air conditioning system etc. and manufacturing-specific physically and/or logically different vehicle data transmission systems (2). The arrangement includes a microcomputer module (3). This operates as a translator for signal communication between the data transmission system (2) and the respective peripheral device (1) under control of an external peripheral interface (7). The microcomputer module (3) cooperates with the peripheral device (1) via an internal interface (6). ADVANTAGE - Inexpensive and flexible system with unlimited application.
