    • A control apparatus for electrically operating a throttle valve adapted to adjust the amount of air drawn into an internal combustion engine to adjust the position of the throttle valve. The position and operating condition of an accelerator pedal are electrically detected to generate a signal in accordance with the accelerator position to drive an actuator adapted to operate the throttle valve, and also a desired throttle position established by the signal, the detected actual position of the throttle valve and the operating condition of the accelerator pedal are suitably compared and examined, thus monitoring to see whether the detection of the accelerator position is not faulty, whether the throttle valve is controlled to follow the desired throttle position and so on and thereby performing a safe control by using a substitute desired position upon occurrence of a faulty condition. Also, during the period of acceleration/deceleration, a driving signal is generated to operate the throttle valve to suit the engine operating condition. Further, when the actuator steps out of synchronism, an evacuation control is performed.

    • 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.

    • This apparatus measures and detects the air-flow taken into an intake pipe of an internal combustion engine, and includes an air-flow detecting sensor. The air-flow detecting sensor comprises a support frame made of heat-resistant insulation material, a heating line supported by the support frame on the upper side when viewed from the direction in which the air-flows, a heat-controlled heating current, and a resistance line also supported by the support frame on the lower side when viewed from the direction in which the air-flows which has a temperature characteristic.

    • An improved fuel injection control apparatus, in which a reference pressure is provided to a pressure regulator, for simplifying the fuel supply system by preventing the fuel quantity injected from injection valves into an engine from being influenced by variations in the air intake pressure. A pressure regulating device disposed in a fuel supply pipe between a fuel pump and the fuel injection valve regulates the pressure of fuel supplied from the fuel pump to the fuel injection valve so that the pressure is proportional to the predetermined pressure, without returning fuel from the injection valve to the fuel tank. An intake pressure detecting device detects the pressure in the intake pipe, and a fuel injection quantity correcting device corrects the fuel injection quantity according to deviations of the fuel pressure regulated by the pressure regulating device from a proper value due to the differential pressure between the pre-determined pressure of the pressure regulating means and the intake pressure. Accordingly, he fuel injection quantity injected from the injection valve is corrected based on the operating condition of the engine due to the variation of the intake pressure. As a result, the fuel supply system is simplified.

    • A traction control system controls the engine torque so as to prevent wheel slip during acceleration. The system has an electric control unit ECU which detects the state of wheel slip on the basis of the deviation of the drive wheel speed from a target drive wheel speed computed in accordance with signals from various sensors such as drive wheel speed sensors, trailing wheel speed sensors, shift position sensor for sensing the shift position in an electronic control transmission ECT, engine speed sensor and accelerator sensor for sensing the amount of operation of accelerator. The ECU computes, in accordance with the state of the slip, a limit drive torque which does not allow surplus wheel slip during acceleration. The ECU also updates the limit drive torque depending on whether the surplus slip takes place on drive wheels, and detects also the amount of operation of the accelerator so as to inhibit updating of the limit drive torque when the detected amount of operation of accelerator is below a value corresponding to a limit throttle opening, whereby the engine is controlled such that the drive torque applied to the drive wheels is maintained below the limit drive torque.
