摘要： A plurality of control systems mounted on a vehicle such as an automobile, and provided for different controlled objects are respectively made of control computers. These control computers are linked by a common data bus. These computers exclusively execute, for example, an engine control, a transmission control, a brake control, a suspension control, and a auto drive control. The data bus is further connected to a diagnosis computer. Each control computer detects a signal from the sensor provided corresponding to each controlled object, and outputs the detect signal to the data bus. Each control computer executes the logical operation for its control on the basis of its detect signal and various data transferred to the data bus. The diagnosis computer supervises an operating state of each control system on the basis of the data transferred to the data bus. When an abnormality is detected, the diagnosis computer stores this data in a large-capacity memory, and displays the abnormality.

摘要： An air flowrate measuring apparatus with a heat wire measures the flow rate of the air flowing through the intake pipe of an engine. The apparatus has a temperature sensitive element which has a specific temperature-resistance characteristic and is disposed in the intake pipe. Constant heating voltage is applied to this element in response to a start signal, thus heating the element. When the temperature of the element rises to a specified value, the application of the voltage is stopped. At the same time, a pulse signal whose width corresponds to the period of applying the voltage is generated. The signal is supplied to an interface circuit through a drive circuit driven by a reference voltage which has been also used to control the heating voltage. The interface circuit comprises two wave-shaping circuits. The first wave-shaping circuit has a filter means of a small integration time constant. The second wave-shaping circuit has a filter means whose integration time constant is large enough to remove noise from the input signal.

摘要： An engine control system has a heater and a temperature measuring element with a temperature-resistance characteristic. The heater and element are provided in the intake pipe of an engine. Heating, which initiated by a start pulse signal generated by an engine control unit in synchronism with engine rotation is supplied to the heater through a transistor. When the heater temperature has reached a reference temperature preset in accordance with the intake air temperature measured by the element, a comparator generates an output to deenergize the heater. The period of supplying the heating power is represented by a pulse signal from a flip-flop. This pulse signal is supplied as an airflow measurement signal to the engine control unit. The engine control unit calculates the basic fuel injection quantity and determines if the starting of the pulse signal received by the control unit falls within a predetermined period from the starting of the start pulse signal. If the starting has fallen outside the predetermined period, the output signal is considered to have been generated in response to a noise signal. In this case, a normal output signal next to the output signal generated in response to the noise signal is corrected.

摘要： A system for controlling the operating condition of an engine in which a temperature sensing element constitutes an airflow measuring device disposed in an intake air passage of the engine. The temperature sensing element is supplied with a heating current in response to a start pulse signal produced with every one-half period of each combustion cycle of the engine. A comparator delivers an output signal when a reference temperature set on the basis of the air temperature measured by an auxiliary temperature sensing element is reached by the temperature of the temperature sensing element. A pulse signal indicative of the time interval between the generation of the start pulse signal and a rise in the output signal of the comparator is delivered as an airflow measurement signal. The average airflow quantity responsive to one combustion cycle of the engine is detected, and a correction factor K is calculated from the difference between two airflow rate data measured in each combustion cycle and the average airflow quantity. Based on the correction factor K, the injection quantity, injection timing and the like are calculated.

摘要： A control system for an engine has a temperature sensitive element as part of a device for measuring the air flow in an air intake manifold to the engine. Further, a first pulse signal is generated, corresponding to the rotation of the engine, for controlling the setting of a flip-flop. A transistor is conducted in the set state of the flip-flop to supply a heating electric current to the element. The element supplied with the current is raised to the temperature that corresponds to the air flow in the manifold. When the temperature of the element is raised until the specified temperature difference to the air temperature (measured by a sub temperature sensitive element) is set, the temperature difference is detected by a comparator, and the flip-flop is reset by the detection signal. A pulse-shaped signal corresponding to the set state of the flip-flop is produced as a measurement output signal, supplied as one detection signal of the operating state of the engine to an engine control unit, and the current to the element is controlled to be supplied by the pulse-shaped signal.
