Monitoring method for motor vehicle controller, e.g. brake system, involves defining reference parameter for measured signal during test phase, detecting error if signal value varies in opposition to it

摘要

The monitoring method involves defining a reference parameter for the measured signal value during a test phase and detecting an error if the signal value varies in opposition to it. The control parameter is the braking pressure in at least two wheel brakes. An Independent claim is also included for an arrangement for monitoring a motor vehicle controller with at least two control loops that regulate a control parameter at two different points depending on a demand value and actual values measured by sensors.
