Oxygen sensor heater control methods and systems |
摘要 |
A control system for an oxygen sensor heater is provided. The control system includes a passive heater control module that generates a heater control signal at a first duty cycle and measures a resistance of the oxygen sensor heater. An exhaust gas temperature mapping module maps the resistance to an exhaust gas temperature. An active heater control module generates a heater control signal at a second duty cycle based on the exhaust gas temperature.
