    • There is provided an ignition timing control device for an internal combustion engine capable of appropriately performing knock learning by performing knock learning adapted to an engine combustion phenomenon. The inventor has found the principle of a knock reduction effect due to ignition retard is that “if a combustion period moves toward the retard side, a cylinder volume during the combustion period increases, resulting in curbing of rise in the temperature and pressure of unburned gas”. An ignition timing control device according to the present invention is capable of new knock learning based on the principle, which learns a “cylinder volume rate”. The cylinder volume rate is a parameter determined from the amount of change in cylinder volume. Even when an operational status changes, learned ignition timing obtained from knock control means can be set to an appropriate value by reflecting the learned cylinder volume rate.
    • 提供一种用于内燃机的点火正时控制装置,其能够通过执行适于发动机燃烧现象的敲击学习来适当地执行敲击学习。 发明人已经发现,由于点燃延迟引起的爆震降低效应的原理是“如果燃烧周期朝向延迟侧移动,则在燃烧期间的气缸体积增加,从而抑制未燃烧气体的温度和压力的升高 “。 根据本发明的点火正时控制装置能够基于学习“气缸容积率”的原理进行新的敲击学习。 气缸容积率是从气缸容积的变化量确定的参数。 即使在操作状态发生变化的情况下,也可以通过反映所知悉的气缸体积速度,将从爆震控制单元得到的点火正时信息设定为适当的值。

    • In an oxygen sensor control apparatus, after start of fuel cut, the weighted average Ipd of corrected values obtained by multiplying the output value of a mounted oxygen sensor by a correction coefficient Kp is obtained as a representative value Ipe, representing the corrected values in the fuel cut period (S19). In the case where the number of times the representative value Ipe is continuously judged not to fall outside a second range (S21: NO) and to fall outside a first range (S23: YES) reaches 10 (a first number of times) (S26: YES), a new correction coefficient Kp is computed (S27). In the case where the number of times the representative value Ipe is continuously judged to fall outside the second range (S21: YES) reaches 4 (a second number of times smaller than the first number of times) (S29: YES), a new correction coefficient Kp is computed (S30).

    • A method for checking a function of an actuator or a sensor of a system, having the following steps: controlling the actuator within a time window if at least one state variable of the system is in a predefined operating range; detecting a system response, with the aid of the sensor, within the time window as a response to controlling the actuator; determining a malfunction of the actuator or of the sensor if the system response differs from a setpoint system response that is expected due to controlling the actuator. A further actuator of the system is controlled during the time window in such a way that the at least one state variable of the system remains in the predefined operating range during the time window. Moreover, a corresponding method for calibrating a sensor or an actuator of a system is described.
