摘要： PURPOSE:To prevent generation of impossible running condition, by allowing a predetermined variable range of a learning control quantity to concide with a conversion data range of an operational unit of a control circuit in a control device for giving a control output quantity with a learning control quantity and a fundamental control quantity. CONSTITUTION:MPU3 in a control circuit 2 receives data for computing a fundamental injection quantity from a rotation sensor 7 and an intake air pressure sensor 10 of sensors 1 so as to compute the fundamental injection quantity. Then, it computes a learning control quantity with data from an O2 sensor 8 and operates an injection quantity with use of both the control quantities as a parameter. When an interruption factor is generated during execution of the above main routine, MPU3 decides whether or not it is a timing for feeding a control output to a member 6 to be controlled, that is, injection valves 18-1-18-n, and if it is such a timing, MPU3 sets data corresponding to an operated injection quantity in a counter 16. After completing such an output processing, MPU returns to the main routine. Thus, in the event that learning data becomes erroneous because of electric noise, etc., there is no possibility of creation of impossible running condition.

摘要： PURPOSE: To enable to properly illuminate according to running spped by a method wherein the luminous intensity of head lights is controlled with controlling signals based on the predetermined running speed versus luminous intensity pattern at the controlling device which automatically controls the illuminating power in accordance with the running speed of the vehicle.
CONSTITUTION: When a normally closed switch 8 automatically controlling the illuminating range of the head lights 3 and 4 is off, the data about running speed is obtained by the signal of a running speed sensor 1 due to the automatic control signal of an automatic control switch 9. The pulse of a duty ratio, which is calculated from said data, is sent to a driving circuit 15 in order to light lamps with high beam by the illuminating power according to the running speed at that time. Furthermore, when no signal from a steering switch 2 is generated, the angle to be change θ is calculated from the characteristic relation of running speed data and numbers of pulses and directional signal in proportion to the deviation of the angle Δθ are given to optical axis controlling actuators 16 and 17 in order to vertically control the optical axes of the head lights 3 and 4 according to the running speed.

摘要： PURPOSE:To ensure optimum ignition time control at any time by a method wherein during the time when a power supply decreases at start-up an engine or a revolving rate is low, ignition is controlled by a fixed ignition signal froma rotary sensor instead of a computing ignition signal in a normal operation.

At the device 1, an optimum ignition time is computed in accordance with a fixed program. A computing ignition signal is generated from a computing ignition signal set-up circuit 4 based on the above computed results. Further, a fixed ignition signal generating circuit 5 is incorportated to generate a fixed ignition signal commanding supply and interruption of a current from the output of the rotary sensor 2 to an ignition coil of an ignition device 8. Ignition signals from both generating circuits 4 and 5 are selected by a duplexer 7 and fed to the ignition device 8. For example, in case a rotating speed of an engine is low, a fixed ignition signal is selected and fed into the ignition device 8.
