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 control apparatus includes a digital processor which receives data from a plurality of sensors which monitor conditions of the engine and supply output signals to the processor for controlling various actuators that control energy conversion functions within the engine. Control signals that are produced in response to data processing operations carried out by the processor are generated in accordance with a selective incrementing of engine timing codes that are successively compared with control data supplied by the processor in response to its processing operations. Selected ones of the control signals are employed to generate interrupts that are supplied to a status register. The contents of the status register are combined with the contents of a mask register to supply interrupts to the processor. The interrupts are assigned in accordance with prescribed levels of priority associated with the data processing operations carried out by the processor. Through the medium of the variable engine control codes supplied by the processor through which control signals for the actuators are eventually produced, the time of occurrence of the interrupts in response to the control signals is controllably variable.

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.
