    摘要: The object of the invention is to provide a low-priced engine control apparatus having a single CPU configuration which can be used for knocking detection and engine control as well, including: an A/D conversion unit which samples, at a predetermined cycle, analog signals of knocking detected and output from a knock sensor; an A/D converter for converting a sampled analog signal to a digital signal in a predetermined conversion time per A/D conversion; a frequency analysis unit which analyzes digital signals upon A/D conversion; a knocking judgment unit which judges the presence of knocking on the basis of a result of the frequency analysis; and a CPU which includes an ignition timing arithmetic unit which executes arithmetic calculation for controlling ignition timing corresponding to knocking on the basis of the judgment so as to ensure an optimum engine control in response to knocking. The predetermined cycle in A/D conversion unit is defined by a period of time which allows for the A/D converter to execute A/D conversion N times, with N being an integer greater than or equal to 2.

    摘要: In order to ensures a stable reduction of noise level at all times, in the steps of switching input voltage with a switching element 10, smoothing the voltage of rectangular wave obtained by switching with a reactor L and capacitor Cf and outputting it, the voltage obtained by dividing the output voltage is compared with the sawtooth wave output from a sawtooth wave generator 14 by a comparator 12. When the switching signal in response to the result of this comparison is applied to the switching element 10, the counter 16 is actuated synchronously with the vertex of the sawtooth wave to perform opening/closing operation of the switch SW1. The time constant of the time constant circuit comprising a R0 and C is adjusted according to whether a resistor R1 is present or not, and the signals of frequencies f1 and f2 coming out of the sawtooth wave generator 14 are sequentially switched to be sent to the comparator 12. The peak of the switching noise is diffused in the frequency range by sequential selection of switching frequencies, and noise level is reduced by diffusion of noise energy.
