摘要： In a detecting apparatus for indicating engine revolutions or vehicle speed, a counter is provided to count up, for a predetermined period of time, the number of pulses produced by an angle sensor. To improve the accuracy of the measurement, the time width during which the pulses are counted can be varied in accordance with a rotational speed of the engine. In this way, a larger measurement time period is provided at lower speeds than at higher speeds.

摘要： An electronic engine control apparatus controls the engine on a basis of the outputs of the digital processor which arithmetically processes output signals from plural sensors for detecting the operating conditions of the engine. Whether or not a pulse to be generated in timing with the rotation of the engine has been generated within a preset period of time, as specified by the digital processor, is checked. If the pulse is generated, a timer for measuring the preset period is cleared. If the pulse is not generated within the preset period, a signal indicating the stopping of the engine is generated, whereby an interrupt signal is generated to cause the digital processor to process the interrupt.

摘要： An electronic control apparatus for an internal combustion engine having engine parameter data sensors, an input/output unit, actuators and a data processing unit carries out a prescribed scenario for starting the engine. The starting sequence begins with the operation of a starting subsystem having a switch the state of which controls the operation of the starter motor. The starter motor is caused to be engaged and a set of initialization procedures are carried out by the data processing unit and input/output unit in dependence upon the state of the switch in the starting subsystem. These initializing procedures include engine operation control calculations as well as system preset steps. During this time, prescribed interrupts which would otherwise be delivered to the data processing unit from the input/output unit are inhibited. However, once the engine has been started, the interrupt inhibit is removed and the system operates under normal conditions.

摘要： A method of electronically controlling the operation of an internal combustion engine is effected on the basis of results of arithmetic operations of digital control quantities derived from detected operating conditions of the engine through digital processing operations. The digital processing operations are subdivided into a number of tasks in dependence on the control functions to be performed. In addition, these tasks are subdivided into a plurality of priority levels. The memory has a task control block having run or execution flag areas in response to the priority levels and start request flag areas in response to the tasks, the start request flag areas being classified in accordance with the levels, in order to make it easy to correct, alter or add tasks. An order for starting the execution of the task is always controlled in accordance with the condition of the run flags and the start request flags.

摘要： An apparatus for controlling the operation of an internal combustion engine having a carburetor, especially, the air-fuel ratio and the rate of exhaust gas recirculation, controls the air-fuel ratio of the air-fuel mixture supplied to the engine in the steady operating condition of the engine on the basis of predetermined data determined relative to the engine crankshaft rotation speed and intake vacuum and stored previously in a memory. A three-way catalyst is used to purify engine exhaust gases, and an output signal from an O.sub.2 sensor in the exhaust system is fed back for the control of the air-fuel ratio in the engine exhaust gases. A circuit is provided to check whether this feedback control is normally carried or not. The air-fuel ratio of the air-fuel mixture supplied to the engine in an unsteady operating condition of the engine is controlled by regulating the amounts of fuel and air supplied to the engine while bypassing the carburetor, on the basis of the sensed values of the intake vacuum, engine crankshaft rotation speed and engine temperature and also depending on the throttle valve position. For the control of the rate of exhaust gas recirculation, an upper limit and a lower limit of the rate of opening of a recirculation rate regulating valve are determined on the basis of the sensed throttle valve opening, and other predetermined data determined relative to the engine crankshaft rotation speed and intake vacuum is read out from the memory to limit the rate of opening of the recirculation rate regulating valve.

摘要： A control system for controlling the opening degree of a solenoid valve provided in an air or fuel supplying system for engine to thereby control the air/fuel ratio of the gas mixture being supplied to the engine. This control system includes a device for accumulating the number of revolutions of the engine from the time the engine starts. When the accumulated value reaches a predetermined value, it is decided that the warming-up of engine is completed. Then, the output of the O.sub.2 sensor for detecting the oxygen O.sub.2 concentration in the exhaust gas is fed back to thereby perform the closed loop control for the air/fuel ratio. Before the accumulated value reaches the predetermined value, the closed loop control is performed without use of the output of the O.sub.2 sensor.
