Method and device for monitoring a computing element in a motor vehicle
First Claim
1. A method for monitoring a computing element in a motor vehicle, the computing element including program modules for influencing the operating performance of said motor vehicle, the method comprising the steps of:
- utilizing said computing element with the aid of said program modules to generate at least one output quantity for controlling at least one function in said motor vehicle in dependence upon at least one input quantity;
selecting at least one of said program modules or at least a part thereof for monitoring the correct function of the computing element;
running through the at least one selected one of said program modules or the at least one selected part thereof or a copy thereof in said computing element on the basis of test data; and
, comparing the result of the test data computation to a pregiven result for fault detection.

Abstract
A method and an arrangement for monitoring a computing element in a motor vehicle are suggested. The computing element generates, with the aid of the program modules, at least one output quantity for controlling at least one function in the motor vehicle in dependence upon at least one input quantity. At least one program module or at least a part thereof is selected for monitoring the correct function of the computing element (12). This at least one selected module or the at least one selected part thereof or a copy is run through in the computing element (12) on the basis of test data and the result of the test data computation is compared to a pregiven result for fault detection.
