摘要： A spark timing control system includes an engine state detecting device for detecting a state of an internal combustion engine. A vehicle vibration (acceleration) detecting device serves to detect a vibration (acceleration) of a vehicle in a longitudinal direction with respect to the vehicle. A target vehicle vibration (acceleration) value calculating device serves to calculate a target vehicle vibration (acceleration) value on the basis of one of results of detections by the engine state detecting device and the vehicle vibration (acceleration) detecting device. A control quantity setting device serves to set a control quantity of a spark timing so as to control the result of detection by the vehicle vibration (acceleration) detecting device at the target vehicle vibration (acceleration) value by use of an optimal feedback gain which is determined according to a dynamic model of the engine. Following conditions are also taken into account: rough road; fuel-cut; transmission-gear; low load.

摘要： In a heater control of an oxygen sensor, a heater control circuit (80) is rendered fully conductive at 100% duty initially to supply full power to a heater (26) until the resistance value of the heater (26) reaches a predetermined initial value corresponding to a predetermined temperature. Then, the duty of the heater control circuit (80) is feedback controlled so that the heater temperature becomes a target value until the internal resistance of the oxygen sensor (S) reaches a target temperature, and further, after the internal resistance of the oxygen sensor S reaches the target temperature, the duty of the heater control circuit (80) is feedback controlled so that the element temperature of the sensor S becomes a target value.
