Abstract
The invention relates to a method and to an arrangement for eliminating false messages in monitoring systems for electronic devices, especially for sensor circuits in motor vehicles. According to the inventive method, error messages increment a counter and an alarm is triggered when a predetermined position on the counter is reached.

A method for suppressing incorrect messages in monitoring system for sensor circuits for motor vehicles, including using a program running on a processor to perform the steps of:
- monitoring at least one input variable and checking whether the at least one monitored input variable exceeds a limiting value defined for the at least one input variable;
- deriving a fault message when the at least one input variable being monitored exceeds the limiting value defined for that at least one input variable;
- incrementing a counter respectively associated with the at least one input variable in response to the fault message;
- checking the counter to determine whether at least one fault message is present for one of the at least one input variable;
- performing the step of monitoring and checking for the one of the at least one input variable if it is determined that at least one fault message is present for the one of the at least one input variable in said step of checking the counter;
- and
- triggering an alarm only if the counter reaches an alarm limit for the at least one input variable.
An arrangement for suppressing incorrect messages in a monitoring system for sensor circuits for motor vehicles, comprising a microprocessor running a program for executing the steps of:
- monitoring at least one input variable and checking whether the at least one monitored input variable exceeds a limiting value defined for the at least one input variable;
- deriving a fault message when the at least one input variable being monitored exceeds the limiting value defined for that at least one input variable;
- incrementing a counter respectively associated with the at least one input variable in response to the fault message;
- checking the counter to determine whether at least one fault message is present for one of the at least one input variable;
- performing the step of monitoring and checking for the one of the at least one input variable if it is determined that at least one fault message is present for the one of the at least one input variable in said step of checking the counter;
- and
- triggering an alarm only if the counter reaches an alarm limit for the at least one input variable.
