Abstract: 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.

Abstract: A control system for an internal combustion engine having at least one control device that affects an air-fuel ratio of an air-fuel mixture to be supplied to the engine, is disclosed. An air-fuel ratio correction coefficient is calculated for correcting an amount of fuel to be supplied to the engine so that the detected air-fuel ratio coincides with a target air-fuel ratio. An air-fuel ratio affecting parameter indicative of a degree of influence that an operation of the control device exercises upon the air-fuel ratio, is calculated. A correlation parameter which defines a correlation between the air-fuel ratio correction coefficient and the air-fuel ratio affecting parameter is calculated using a sequential statistical processing algorithm. A learning correction coefficient relating to a change in characteristics of the control device is calculated using the correlation parameter. The air-fuel ratio is controlled using the air-fuel ratio correction coefficient and the learning correction coefficient.
