Abstract: In order to make it possible to simply carry out a realistic test on a vehicle or a sub-system of the vehicle including a control unit that processes the sensor values of a measured quantity , on a test bench, and taking into account the state of the vehicle dynamics, the control unit is switched into a testing mode in order to carry out the test run. Calculated values of the same measured quantity are calculated in a simulation unit and the calculated values of the measured quantity are supplied to the control unit in addition to the detected sensor values of the measured quantity. In testing mode, the control unit ignores the detected sensor values of the measured quantity and omits the plausibility check of the calculated values of the measured quantities.

Abstract: In a method for monitoring a functionality of a first and a second component of a motor vehicle the requirements for the monitoring are as follows: for a valid monitoring of the first component a predetermined operating condition of the motor vehicle must exist; for a valid monitoring of the second component the first component must be functioning properly. According to the method according to the invention, upon impending travel, taking into account navigation data of a navigation assistance system, it is determined whether the prescribed operating condition is expected to exist.
