Abstract
The invention proposes a method and apparatus for monitoring operating and/or driving parameters of a motor vehicle, whereby the measured data for monitoring the operating and/or driving functions supplied by a sensor are checked by the control function in dependence on the inclination angle of the motor vehicle in the longitudinal or transverse direction of the vehicle. If a specified limit for the inclination angle is exceeded, the error message is suppressed if the detected error occurs only briefly. Error messages relating to the fluid level in the tank cooling-water compartment, engine compartment, and transmission compartment can therefore be suppressed. The error is output only when an actual error exists the remains for a longer period of time. In an alternative embodiment of the invention, it is provided that error messages also be detected and evaluated as a function of dynamic driving parameters such as rotational speeds and/or accelerations. A preferred application is in off-road vehicles.
