    摘要： Sensors detect parameters. Control units control vehicle equipments in accordance with the detected parameters. In each of the control units, at least one of the detected parameters and internally produced data is converted into serial data as communication data, and serial data is converted into other form data.

Each of the serial interfaces includes a connection terminal connected to the transmission medium, an input terminal and an output terminal both connected to the associated control unit. Each of the serial interfaces inputs serial data from the associated control unit via its input terminal and outputs the inputted data to the transmission medium via its connection terminal. Each of the serial interfaces inputs serial data from the transmission medium via its connection terminal and outputs the inputted data to the associated control unit via its output terminal.

    摘要： A communication system includes a plurality of separate transmission units. A common signal line connects the units. A token is transferred from a first of the units to a second of the units during one sequence. The token is a right to output data to the common signal line. When the token is rejected by the second unit, the token is retransferred from the first unit at maximum a predetermined number of times during that sequence to the second unit. When the retransferred token is rejected by the second unit, the token may be transferred from the first unit to a third of the units during that sequence. In a next sequence, said predetermined maximum number of times said token is retransmitted to said second unit is then reduced.

    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 method generally applicable to those control systems of the engine such as an ignition system, fuel injection system, etc., which are controlled to optimum operation in accordance with engine operating conditions. Angular pulses are generated each time the output shaft of the engine rotates a predetermined angular amount. These angular pulses are counted from the occurrence of a position pulse which is generated at a predetermined angular position of the output shaft of the engine. A central processor is employed to calculate a first angular position at which an electric device for the engine is to be controlled. The central processor also calculates a time interval between the first angular position and a second angular position at which one of the angular pulses is to be provided just before the first angular position. When the angular pulse counting reaches a value corresponding to the second angular position, fixed frequency clock pulses are then counted. When the calculated required time interval has passed as determined by counting the fixed frequency clock pulses, the electric device is controlled.

    摘要： Disclosed is an azimuth determination apparatus attached to a motor vehicle for determinating the forward direction of the vehicle. The azimuth determination apparatus includes an azimuth sensor for generating orthogonal first and second signals indicative of the forward direction of the vehicle. Two azimuth vectors are obtained on the basis of the orthogonal first and second component signals, first components of the two azimuth vectors being maximum and minimum. The determination is made in terms of the fact that the difference between second components of the two azimuth vectors is below a predetermined value. In accordance with the determination, the orthogonal first and second component signals are corrected on the basis of said two azimuth vectors so that the accurate moving direction of the motor vehicle can be obtained irrespective of the remanence of the vehicle.
