    • In a speed control system for vehicles, a speed difference calculation circuit calculates an absolute value of a time difference between a predetermined period of time corresponding with a desired speed and an instant period of time corresponding with the actual speed, an acceleration calculation circuit calculates an absolute value of a time difference between the respective instant periods of time, and a correction signal generator calculates a sum of the absolute values in consideration with the actual speed when each sign of the calculated time differences is positive or negative and calculates a difference between the absolute values in consideration with the actual speed when respective signs of the calculated time differences are opposite to each other. The signal generator selectively produces correction signals related to the calculated sum and the calculated difference. A distribution circuit produces a control signal in response to the respective correction signals, and an actuator controls the opening angle of the engine throttle in response to the control signal.

    • A vehicle speed control system includes a first generator for producing an operation signal upon closure of a set switch at a desired vehicle speed and receipt of a timing signal from a second generator responsive to the actual vehicle speed, the operation signal disappearing in response to one of the subsequent timing signals. A first calculator calculates a first time difference between predetermined and instant time periods respectively defined by the desired and actual vehicle speeds, and a second calculator calculates a second time difference between the respective instant time periods. A third generator produces a correction signal defined by the second time difference during generation of the operation signal and produces another correction signal defined by the sum or a difference of the time differences in relation to identical or opposite signs of the time differences after disappearance of the operation signal. A distribution circuit is responsive to one of the correction signals to produce an output signal relative to the sign of the second time difference such that an actuator controls an engine throttle opening angle.

    • An apparatus for controlling an ignition coil of internal combustion engines including a power transistor connected to the primary winding of an ignition coil for controlling the energization and deenergization of the primary winding in response to a signal applied to the base of the power transistor. A feedback circuit, including a constant voltage diode, a capacitor and a resistor, is connected between the collector and base of the power transistor. When the power transistor becomes conductive from a nonconductive condition, a collector current of the power transistor flows through the capacitor and constant voltage diode due to the Miller integrator effect and the transition from nonconduction to conduction of the power transistor is made gradual thereby reducing a voltage generated in the secondary winding of the ignition coil. On the contrary, when the power transistor becomes nonconductive from the conductive condition, the constant voltage diode is rendered conductive due to a high voltage generated at the collector of the power transistor to allow a base current to flow and in turn to allow a collector current thereby preventing breakdown of the power transistor.

    • PURPOSE:To increase torque output by performing feedback control of ignition timing by detection and discrimination of knocking when an engine is not in a specific running condition and by performing ignition timing control set in accordance with the engine condition when it is in a specific running condition. CONSTITUTION:When an engine is running, it is judged first whether the engine is in a specific running condition (at the time of low rotation when the engine temperature is low as under the predetermined value or the number of engine rotation is less than the predetermined value) or not in an ignition angle setting circuit 11, and if the engine is in the specific running condition, the ignition timing is set to a lead angle value determined by the number of engine rotation and air in-take negative pressure. While when it is not in the specific running condition and knocking signal is given from a knocking discriminating circuit 9, a lead angle value is obtained by subtracting a step lead angle value from the present lead angle value theta. When the lead angle value is over the maximum lead angle value thetamax which is set previously, it is se to the lead angle value thetamax. When it is below the set lead angle value thetap which is set in accordance with the running condition, it is set to the lead angle value thetap.
