摘要： 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.

摘要： PURPOSE:To ensure a smooth and high-accuracy control for the constant-speed traveling of vehicles, by avoiding the lowering of accuracy for the width value of the control signal of the fuel supply amount although the period of the timing signal is reduced to an increment of the traveling speed. CONSTITUTION:The timing signal generating circuit 130 produces the gate signal and the latch signal in response to the clock signal. Thus the counters 171-173 of the car speed calculator circuit 170 perform an up-counting each. Then the counters 172 and 173 apply the binary signal having a period difference of ¦T1-Tm¦ to the latch circuits 177 and 178, and the code signal showing the minus is applied to the correction signal generating circuit 190. On the other hand, the counters 183a-183c of the acceleration counter circuit 180 perform an up-counting each. Thus the counters 183a and 183b send the binary signal of the period difference ¦Tm-1-Tm¦ to the latch circuits 186a and 186b. This binary signal is then applied to the circuit 190 as a binary signal.

摘要： PURPOSE:To reduce failures in a simple structure by providing a rotatable member with respect to a housing and a fixed rotation-blocking means. CONSTITUTION:When an automobile which has been running at a constant speed comes to an upward slope, the speed is decreased from the predetermined speed. When a pinion gear 27 which is provided on the output side of a motor 11 is rotated with an electromagnetic coil 46 being conducted, a flat gear 28 and a large driving gear 30 are rotated. When the gear 30 is rotated, a planetary gear 33 (differential gear), whose rotating shaft is a shaft 32 which is fixed to the said gear 30, rotates and at the same time revolves around a large differential gear 36 on the output side and a large differential gear 37 on the clutch side. In this case, since the rotation of a clutch plate 40 is stopped by the acceleration of an electromagnetic clutch 12 and the gear 37 does not rotate, the gear 36 rotates differentially with respect to the gear 37, thereby an output rotary shaft 17 is rotated. A throttle valve is driven via an output arm of an electric actuator 7, the speed of the automobile becomes the desired value. In this method, the failures are reduced.
