METHOD OF OPERATING A DRIVE DEVICE AND CORRESPONDING DRIVE DEVICE |
| 摘要 |
In a method of operating a drive device, a probe temperature of an exhaust gas exhaust gas probe in an exhaust tract is measured, as the exhaust gas probe is heated by a probe heater. A temperature growth value representative of an increase in temperature of the exhaust gas probe is determined during heating of the exhaust gas probe, and the presence of a defect of the probe heater is recognized, when the temperature growth value deviates from an input value. |
