Control system and method for oxygen sensor heater control |
摘要 |
The present disclosure provides a control system for a heating element used in an oxygen sensor. The control system comprises a rate module that periodically determines a rate of change of current through the heating element and a temperature adjustment module that periodically compares the rate of change and a rate value. The temperature adjustment module selectively adjusts an operating temperature of the oxygen sensor between a normal temperature and a remedial temperature lower than the normal temperature based on the comparison of the rate of change and the rate value. The present disclosure also provides a related control method for the heating element. |
