摘要： When normal operation is detected by a self-interruption signal source and a first transistor is on, if an on-signal is inputted to an IN terminal, a second transistor is turned on and a third transistor is turned off. Accordingly, an IGBT is turned on. In this state, if an abnormality is detected by the self-interruption signal source, the second transistor is turned off and the third transistor is turned on. Accordingly, a gate terminal of the IGBT is connected to an emitter terminal via the first and third transistors, and charges accumulated by gate capacitance of the IGBT are rapidly discharged. Consequently, if a comparator detects that a collector voltage of the IGBT has exceeded a predetermined voltage, the first transistor is turned off, and a gradual interruption, in which the charges accumulated by the gate capacitance are gradually released by a resistor, is performed.
摘要翻译：当通过自中断信号源检测到正常操作并且第一晶体管导通时，如果将ON信号输入到IN端子，则第二晶体管导通，并且第三晶体管截止。因此，IGBT被导通。在该状态下，如果由自中断信号源检测到异常，则第二晶体管截止，第三晶体管导通。因此，IGBT的栅极端子经由第一和第三晶体管连接到发射极端子，并且由IGBT的栅极电容累积的电荷被快速放电。因此，如果比较器检测到IGBT的集电极电压已经超过预定电压，则第一晶体管被截止，并且由栅极电容累积的电荷逐渐被电阻器释放的逐渐中断被执行。

摘要： Methods and devices are described that utilize skip fire techniques to rapidly meet requests for transitory changes in the output of an engine. Specifically, the fraction or percentage of the working cycles that are fired can be changed during a transitory event so that the engine delivers the desired transitory engine output. Once the transitory event is over, normal engine operation may be restored. The described techniques are useful in a variety of applications that require a relatively quick, but transitory, reduction in engine output to meet vehicle control requirements. One particularly useful application is during transmission shift events. Other representative applications include: loss of traction events, stability control events, wheel hop prevention events, etc.

摘要： The invention concerns a method for controlling at least one of a fuel supply and an air supply to an internal combustion engine (1), in a fuel supply section thereof, such that an A/F-ratio is adjusted automatically to a desired level. Moreover, the method is activated at a speed close to a cut-out speed threshold (52) where the engine speed will fluctuate around the threshold (52) and the method comprises the steps of : receiving engine speed data on rotational speed from the engine (1), briefly changing the A/F ratio, comparing engine speed data that are essentially unaffected by the brief change to engine speed data that are affected by the brief change to evaluate the impact on the engine speed fluctuation resulting from the brief change, adjusting the A/F ratio in the same direction as the brief change if the engine speed data affected by the brief change indicates an increase in acceleration after combustion/s, and adjusting the A/F ratio in the opposite direction to the brief change if the engine speed data affected by the brief change indicates a decrease in acceleration after combustion/s.
