    • The apparatus of the present invention corrects a control target value of ignition timing using a multipoint learned value AGdp(n) for compensating for a change amount of the ignition timing caused by time-dependent change of the engine and a basic learned value AG(i) for compensating for a change amount of the ignition timing caused by a factor other than the aforementioned time-dependent change of the engine. In a multipoint learning range n in which the time-dependent change of the engine influences the ignition timing to a great extent, the control target is corrected using the multipoint learned value AGdp(n) and the basic learned value AG(i). In ranges other than the multipoint learning range n, the control target is corrected using only the basic learned value AG(i). Normally, only the learning of the multipoint learned value AGdp(n) is permitted in the multipoint learning range n, and only the learning of the basic learned value AG(i) is permitted in the ranges other than the multipoint learning range n. When it is determined that there is a possibility that fuel has been fed to a fuel tank, the learning of the multipoint learned value AGdp(n) is prohibited for a subsequent predetermined period (if NO in step S103 or step S104).
    • 本发明的装置使用多点学习值AGdp(n)来校正点火正时的控制目标值,用于补偿由发动机的时间变化引起的点火正时变化量和基本学习值AG(i ),用于补偿由除了上述发动机的时间变化之外的因素引起的点火正时变化量。 在发动机的时间相关变化很大程度上影响点火正时的多点学习范围n中,使用多点学习值AGdp(n)和基本学习值AG(i)来校正控制对象。 在多点学习范围n以外的范围内,仅使用基本学习值AG(i)来校正控制对象。 通常,在多点学习范围n中仅允许多点学习值AGdp(n)的学习,并且在除了多点学习范围n以外的范围内仅允许学习基础学习值AG(i)。 当确定燃料已经被供给到燃料箱的可能性时,多个学习值AGdp(n)的学习在随后的预定时间段被禁止(如果在步骤S103或步骤S104中为否)。

    • A switching element is controlled by a control circuit. When the switching element is in an ON state, a coil current I.sub.L ramps up. When the switching element is in an OFF state, the coil current I.sub.L ramps down. If an output voltage V.sub.out is smaller than a predetermined output voltage value, a control circuit is informed of it. If the coil current I.sub.L rises to a peak current I.sub.LP set by a setting circuit, the control circuit is informed of it. The setting circuit sets the peak current I.sub.LP proportional to an input voltage V.sub.in. The control circuit sets the switching element in the ON state when the output voltage V.sub.out is smaller than the predetermined output voltage value, and sets the switching element in the OFF state when the coil current I.sub.L rises to the peak current I.sub.LP.
    • 开关元件由控制电路控制。 当开关元件处于导通状态时,线圈电流IL上升。 当开关元件处于断开状态时,线圈电流IL下降。 如果输出电压Vout小于预定的输出电压值,则通知控制电路。 如果线圈电流IL上升到由设定电路设定的峰值电流ILP,则通知控制电路。 设置电路设置与输入电压Vin成比例的峰值电流ILP。 当输出电压Vout小于预定的输出电压值时,控制电路将开关元件设置在ON状态,并且当线圈电流IL上升到峰值电流ILP时,将开关元件设置在OFF状态。
