摘要： 이발명은아이들시의엔진회전수제어방법에관한것이다. 자동차에시동이걸리면엔진제어부가제1 목표회전수로아이들속도조절부를구동시키고, 배터리전압, 냉각수의온도및 변속기의오일온도를측정하여해당하는설정값들과비교한다. 배터리전압이제1 전압보다크고냉각수의온도가제1 온도보다크며오일의온도가제2 온도보다큰 경우, 이러한제1 구동상태가제1 설정시간동안유지되면목표회전수를제1 목표회전수에서제2 목표회전수로변화시켜아이들속도조절부를구동시킨다. 또한제2 목표회전수로아이들속도조절부를구동시키는상태에서, 배터리전압이제2 전압보다작거나상기제1 구동상태를위한조건들이하나라도만족되지않는경우에는목표회전수를제2 회전수에서제1 회전수로변화시켜아이들속도조절부를구동시킨다. 이와같이차량구동상태에목표회전수를변화시켜엔진제어를수행함에따라, 엔진변화및 외부영향변화가발생한경우에도아이들시의엔진회전수가목표회전수에바로도달함에따라응답성이향상되고, 연비가향상된다.

摘要： PURPOSE: In a connector failure of an intake air sensor, an engine stall is prevented caused by an inconformity of an intake air amount and fuel amount. CONSTITUTION: An air amount is measured sensed by an air amount sensor(30). A modelling process of the measured air amount is carried out as an air amount by an engine rpm and throttle opening degree(31). It is decided whether it is within a predetermined time(C1) after engine start(32). If it is within the predetermined time(C1), it is decided whether it is below the least air amount to prevent an engine stall or whether it is above the most air amount to determine failure(33). If the modelling air amount is not below the least air amount to prevent the engine stall and is not above the most air amount to determine failure, it is not failure counted with the measured air amount(34). If the modelling air amount is below the least air amount to prevent the engine stall and is above the most air amount to determine failure, it is not failure counted with the modelled air amount(35).

摘要： PURPOSE: A driving method for an engine by using a cam sensor is provided to start and drive the engine regardless of failure in operation of a crankshaft position sensor. CONSTITUTION: After starting an engine, traveling state of a vehicle is decided. A tolerance error in a falling edge and a rising edge of a cam sensor is compared with an established value. In case of the tolerance error under the established value, normal operation of the cam sensor is decided. In case of an error in a crankshaft position sensor, a time for one tooth is calculated in an ECU(Electronic Control Unit) by using a signal from the cam sensor while controlling fuel injection and ignition. Therefore, the fuel injection and the ignition are performed by using the cam sensor according to failure in the crankshaft position sensor. Thus, reliability on the vehicle is improved.

摘要： PURPOSE: Detecting device and method for the malfunction of a valve are provided to check the operation of the valve according to the operation of a cam sprocket and a crank sprocket by each stroke of an engine. CONSTITUTION: An electronic control unit receives an engine output, battery voltage, and the temperature of cooling water from a vehicle speed sensor, a voltage sensor, and a water temperature sensor to decide the operation state of a vehicle. In case of a normal operation state of the vehicle, input of signals from a cam sensor and a crank position sensor is decided. By input of the signals, errors in the cam sensor and the crank position sensor are detected. In case of detection of the errors, a second alarming instrument is operated. In case of normal states of the cam sensor and the crank position sensor, the electronic control unit receives first and second signals from the crank position sensor and the cam sensor. Then, the first signal corresponding to an elevating terminal and a lowering terminal of the second signal is detected for deciding an order of a tooth on a crank target wheel generating the first signal. In case of the order of the tooth of the crank target wheel located within a normal range, the normal operation of the vehicle is decided. Otherwise, malfunction of the vehicle is decided for operating the second alarming instrument.
