摘要： PROBLEM TO BE SOLVED: To converge a rotational speed to a target rotational speed in a short time when an engine is started. SOLUTION: The electronic control unit (ECU) 10 of an engine 1 performs either of an intake air amount rotational speed control controlling an engine rotational speed to a target rotational speed by adjusting the opening of the electronic throttle valve 16 of the engine according to the rotational speed in starting the engine, and an ignition timing rotational speed control controlling the engine rotational speed to a target rotational speed by adjusting the engine ignition timing. The ECU controls a throttle opening in the intake air amount rotational speed control and an ignition timing in the ignition timing rotational speed control by a feedback control based on a deviation between the target rotational speed and an actual rotational speed, and sets feedback control constants in the feedback control according to the deviation of the rotational speed and a time change rate. Thus, since the change rate of the engine rotational speed can be set properly, the engine rotational speed can be converged to the target rotational speed in a short time without causing overshoot.

摘要： PROBLEM TO BE SOLVED: To diagnose deterioration in a sensor precisely regarding an apparatus for diagnosing deterioration in the sensor for vehicles, in which the response speeds differ, depending on the active state.
SOLUTION: The apparatus for diagnosing deterioration in the sensor diagnoses deterioration, with respect to an oxygen concentration sensor, or the like, provided at the exhaust passage of an internal combustion engine. A sensor, such as the oxygen concentration sensor, changes the response time, depending on the temperature and allows the response speed to be faster, the higher the temperature is. The oxygen concentration sensor, having these characteristics, have a relatively high response speed at high temperatures, even if it has deteriorated, so that the difference in the response speed, as compared with a normal sensor becomes small, making accurate determination difficult. Therefore, the apparatus for diagnosing deterioration in the sensor diagnoses deterioration in an inactive state, in which the difference between the response speed of the normal sensor and that of a deteriorated sensor appears marked; namely, when the temperature of the sensor is low, diagnosing of deterioration is conducted. As a result of this, diagnosis of deterioration can be carried out with high accuracy.
