A method for avoiding error messages due to maintenance work on a vehicle, which are generated by a monitoring unit if one or multiple operating parameters of a monitored vehicle system are outside of a predefined, admissible value range. Accordingly, the general driving operation is monitored with the aid of a vehicle's own sensor system with respect to a maintenance state and, if a maintenance state is established, the admissible value range be automatically extended or at least one operating parameter is ignored during monitoring.

1. A method for avoiding error messages due to maintenance work on a vehicle, the method comprising: detecting, using a sensor system, whether the vehicle is in a maintenance state, wherein a monitoring unit for monitoring a reliability performance of a vehicle system generates the error messages when one or multiple operating parameters of the vehicle system are outside a predefined admissible value range, and wherein the monitoring unit generates the error messages irrespective of whether the vehicle is in the maintenance state; andperforming, if the maintenance state has been detected by the sensor system, at least one of (i) automatically extending the admissible value range, and (ii) increasing an error latency time of at least one operating parameter. 2. The method of claim 1, wherein the maintenance state is detected with at least one of a wheel speed sensor, a gear position sensor, an ignition switch sensor, and an engine speed sensor. 3. The method of claim 2, wherein the vehicle system is a brake system of the vehicle, and wherein the at least one operating parameter is at least one of a brake pressure, a brake piston path, and a pump run time of a hydraulic pump. 4. The method of claim 1, wherein the vehicle system is a brake system of the vehicle, and wherein the at least one operating parameter is at least one of a brake pressure, a brake piston path, and a pump run time of a hydraulic pump. 5. The method of claim 1, wherein a threshold value which represents a limit of the value range is modified so that the value range is extended. 6. A control unit for avoiding error messages due to maintenance work on a vehicle, comprising: a sensor system that detects whether the vehicle is in a maintenance state, wherein a monitoring arrangement for monitoring a reliability performance of a vehicle system generates, irrespective of whether the vehicle is in the maintenance state, the error messages when one or multiple operating parameters of the vehicle system are outside a predefined admissible value range; anda control arrangement to perform, if the maintenance state has been detected by the sensor system, at least one of (i) automatically extending the admissible value range, and (ii) increasing an error latency time of at least one operating parameter. 7. The control unit of claim 6, wherein the maintenance state is detected with at least one of a wheel speed sensor, a gear position sensor, an ignition switch sensor, and an engine speed sensor. 8. The control unit of claim 7, wherein the vehicle system is a brake system of the vehicle, and wherein the at least one operating parameter is at least one of a brake pressure, a brake piston path, and a pump run time of a hydraulic pump. 9. The control unit of claim 6, wherein the vehicle system is a brake system of the vehicle, and wherein the at least one operating parameter is at least one of a brake pressure, a brake piston path, and a pump run time of a hydraulic pump. 10. The control unit of claim 6, wherein the control arrangement extends the admissible value range by modifying a threshold value which represents a limit of the admissible value range.
