請參照圖4，本發明之一實施例的引擎迴轉訊號調變裝置100，其中訊號處理部4用以依據調變控制訊號來調變訊號B並將特徵波形W2提前，例如調變成訊號B”，其中訊號B”的特徵波形W’較訊號B的特徵波形W2提前出現。訊號處理部4亦可調變將特徵波形延遲(圖未示)。訊號處理部4調變特徵波形提前或延遲的程度是依訊號處理部4所接收到的調變控制訊號來決定。 Referring to FIG. 4, an engine rotation signal modulation device 100 according to an embodiment of the present invention, wherein the signal processing unit 4 is configured to modulate the signal B according to the modulation control signal and advance the characteristic waveform W2, for example, into a signal B. The characteristic waveform W' of the signal B" appears earlier than the characteristic waveform W2 of the signal B. The signal processing unit 4 can also modulate the characteristic waveform by delay (not shown). The degree to which the signal processing unit 4 adjusts the characteristic waveform advance or delay is determined by the modulation control signal received by the signal processing unit 4.

圖5為本發明之另一實施例之引擎迴轉訊號調變方式的示意圖。波數與波形僅為示意之用，本發明不限於此。原始的引擎迴轉訊號R為一交流訊號。經濾波及整流後的引擎迴轉訊號A已轉換成方波脈衝訊號，此時的引擎迴轉訊號尚未經訊號處理部4處理。 FIG. 5 is a schematic diagram of a method for adjusting a rotary signal of an engine according to another embodiment of the present invention. The wave number and waveform are for illustrative purposes only, and the invention is not limited thereto. The original engine gyro signal R is an ac signal. The filtered and rectified engine revolution signal A has been converted into a square wave pulse signal, and the engine rotation signal at this time has not been processed by the signal processing unit 4.
請參照圖5，本發明之一實施例的引擎迴轉訊號調變裝置100，其中訊號處理部4用以依據調變控制訊號來調變訊號A的脈波數目。以引擎迴轉訊號A為例，引擎迴轉訊號A一個周期有12個脈波(圖示為2個周期共24個脈波)。經過訊號處理部4調變後可產生一個周期多於12個脈波的訊號，例如訊號C一個周期有24個脈波(圖示為2個周期共48個脈波)，或是少於12個脈波的訊號(圖未繪示)。即訊號處理部4可對訊號的脈波數目進行調變。12個脈波或24個脈波在此僅為舉例說明之用，本發明不限於此。脈波數目最少需1個以上，視引擎點火控制需要而定，本發明對此不加以限定。調變增加引擎迴轉訊號A一個周期中的脈波數目可令迴轉訊號成份分割的更細，對於訊號的時間控制能更精細。 Referring to FIG. 5, an engine rotation signal modulation device 100 according to an embodiment of the present invention, wherein the signal processing unit 4 is configured to modulate the number of pulses of the signal A according to the modulation control signal. Taking the engine rotation signal A as an example, the engine rotation signal A has 12 pulses in one cycle (the figure shows 24 pulses in 2 cycles). After the signal processing unit 4 is modulated, a signal with more than 12 pulses can be generated. For example, the signal C has 24 pulses in one cycle (there are 48 pulses in 2 cycles), or less than 12 Pulse signal (not shown). That is, the signal processing unit 4 can modulate the number of pulses of the signal. 12 pulses or 24 pulses are used herein for illustrative purposes only, and the invention is not limited thereto. The number of pulse waves needs to be at least one or more, depending on the needs of the engine ignition control, which is not limited by the present invention. Modulation increases the number of pulses in one cycle of the engine's rotary signal A to make the segmentation of the rotary signal component finer, and the timing control of the signal can be finer.

For example, it is converted into a signal C', in which the characteristic waveform W" is earlier than the characteristic waveform W of the signal C. Now. The signal processing unit 4 can also modulate the characteristic waveform W by delay (not shown). The degree of advancement or delay of the modulation characteristic waveform W by the signal processing unit 4 is determined by the modulation control signal received by the signal processing unit 4. In practical applications, for example, when a characteristic waveform is detected by an ignition circuit or a capacitor discharge ignition device, the discharge ignition operation is started. Therefore, the advance or delay of the modulation characteristic waveform can affect the timing of the engine ignition.

Referring to FIG. 7, the engine rotation signal modulation device 100 picks up the engine rotation signal R sent from the crankshaft position sensor 10 to the electronic control unit (ECU) 9, and generates an output signal F and transmits it to the capacitor discharge. Ignition device 7. The capacitor discharge igniting device 7 generates an ignition waveform according to the received output signal F to send electric energy to the spark plug 8 for discharge ignition. The engine rotation signal R is a signal from the crankshaft position sensor 10 that senses the crankshaft itself or senses a synchronous rotating member with the crankshaft. The type and arrangement of the crankshaft position sensor 10 of the present invention are not limited.
基於上述，本發明的實施例至少具有以下其中一個優點。由於本發明之實施例之引擎迴轉訊號調變裝置採用訊號處理部，可調變引擎迴轉訊號的脈波數目、脈波寬度、提前或延遲特徵波形或將第一特徵波形改成第二特徵波形等至少其中之一種調變方法，因此至少具有較精密的調整方式、較高的適用性、及較佳的匹配性的其中一個優點。 Based on the above, embodiments of the present invention have at least one of the following advantages. The engine rotary signal modulation device of the embodiment of the present invention uses a signal processing unit to adjust the pulse wave number, pulse width, advance or delay characteristic waveform of the engine rotation signal or change the first characteristic waveform to the second characteristic waveform. At least one of the modulation methods, and therefore at least one of the advantages of a more precise adjustment method, a higher applicability, and a better matching.
