Controller for controlling element temperature of exhaust gas sensor |
摘要 |
A controller for controlling a temperature of an element disposed in an exhaust gas sensor is provided. The exhaust gas sensor further comprises a heater for heating the element. The controller comprises a control unit. The control unit performs response assignment control to determine a duty ratio of energization of the heater. In one embodiment, the response assignment control uses a switching function that specifies a response of the element temperature to a target temperature. The energization duty ratio is determined based on the integral of the switching function. In one embodiment, the element temperature of the exhaust gas sensor is estimated. The control unit determines the energization duty ratio of the heater based on the estimated element temperature. The element temperature may be estimated based on the temperature of exhaust gas.
