Diagnostic system for multiplex on-board network of motor vehicle based on stored reference values for comparison with actual operating conditions

摘要

The outputs of sensors (4,5,6) for, e.g. speed,engine RPM and brake pressure, are connected to a data bus (7) connected to a memory (3) which stores reference values for engine, motor and drivers performance for diagnosis by an on-board processor (8) and/or a computer (1). If both are present current conditions can be processed by the processor with the computer drawing on the stored information for detailed diagnosis
