摘要： In an apparatus for controlling an internal combustion engine having a fuel injection control system, the detected number of revolutions is so modified that it becomes higher than an actual number of revolutions when a changing rate of the number of revolutions is larger than a predetermined value and the actual number of revolutions tends upward, and lower than the actual one when the changing rate is larger than the predetermined value and the actual number of revolutions tends downward. The quantity of fuel to be injected is calculated on the basis of the thus modified number of revolutions. According to the present invention, the deceleration shock or surging occurring during the low speed running of an automobile can be effectively diminished without any deterioration of the exhaust gas.

摘要： An altitude decision system and engine operating parameter control system using the same for accurately detecting and correcting for altitude uses three signals, viz, the signal from an engine revolution number sensor, the signal from a throttle sensor for detecting the angle of opening of a throttle valve, and a fundamental fuel injection pulse width signal which is computed by engine operational parameter-computer from inputted signals from a mass air flow sensor and the revolution number detection sensor. Having accurately derived the altitude, the fuel injection pulse rate, the intake air flow and the ignition timing are corrected.

摘要： A detection processing of a rotational number of an engine is executed periodically in synchronism with a rotation of the engine. A calculation processing of an ignition timing correction amount (.DELTA.IGN) is executed periodically in every predetermined time independently on the rotational number detection of the engine. After the engine is accelerated, the ignition timing control of the engine is executed based on the ignition timing correction amount.

摘要： A control apparatus for an automobile is provided with a system manager, which initiates and manages the operation of units for controlling and operating various devices and accessories installed in the automobile. The system manager is coupled with a card unit, in which a card is inserted. Such a card has an identification code ID of a user and a code indicating that the card is registered in advance. The system manager has a list of codes of cards registered. If a card inserted is confirmed to be correct and valid by the ID and the registration code, the system manager executes a predetermined processing operation and produces a set-up instruction signal. Upon receipt of this set-up instruction signal, operations of the control units for the devices and accessories are initiated.
