摘要： The rate of variation in the rotational period of an engine is determined by the use of a pulse signal generated according to the rotation of an engine crankshaft, and the value of the rate of variation thus determined is compared with a previously set value of judgement of the rate of variation. When the rate of variation is under the judged value, ignition is performed at an advance or retard timing given by calculation; and when the rate of variation exceeds the judged value, an ignition signal is used as a reference crank position signal in place of an ignition command signal obtained by calculation.

摘要： A following control apparatus for an automotive vehicle is disclosed which controls the output of an engine and the brakes of a vehicle so as to maintain a target vehicle separation from a preceding vehicle. A control unit calculates a target drive force for the vehicle and controls the brakes and the throttle valve of the engine so as to achieve the target drive force. In one form of the invention, the target drive force when the vehicle is starting from a standstill is calculated based on the relative speed of the vehicle and the preceding vehicle and the difference between the measured vehicle separation and the target vehicle separation when the measured vehicle separation is at least the target vehicle separation, but is calculated based on the relative speed of the vehicle independently of the vehicle separation when the measured vehicle separation is less than the target vehicle separation. In another form of the invention, the target drive force when the vehicle is starting from a standstill is calculated based on the relative speed of the vehicle and the preceding vehicle and the difference between the measured vehicle separation and the target vehicle separation, with the target drive force being greater when the vehicle speed is less than a predetermined value than when the vehicle speed is greater than the predetermined value.

摘要： A method for reducing knocking in an internal combustion engine providing an improved response to changes of operating conditions of the engine and which is capable of producing precise knocking control under all combinations of operating conditions. The knocking level, load condition and rotational speed of the engine are detected. At addresses of a memory defined by the load and speed of the engine, values are stored which are calculated in accordance with the detected knocking levels, and ones of these values are read out in accordance with addresses corresponding to a present combination of a load condition and engine speed. At least one control parameter, such as the ignition timing, is corrected on the basis of the values read out from the memory and the detected knocking level. The values stored in the memory are changed at predetermined periods bidirectionally.
