摘要

The control device 110 comprises a timer module 114 and a central processing unit (CPU) 120 and is connected to a crankshaft position sensor 102. The CPU 120 is designed to recognize interrupts on each edge of a position signal that is received from the crankshaft position sensor 102, and to detect the engine position when the interrupt is received. The CPU 120 also initiates ignition and injection based on the detected engine position. The control device 110 is characterized in that it deactivates and activates interrupts from the timer module 114 on the basis of a detection of the predetermined event. In particular, the CPU 120 deactivates the generation of interrupts from the timer module 114 as soon as the motor position is detected, and activates the receipt of an interrupt generated by the timer module 114 when the predefined event occurs. The present invention results in fewer interrupts and less load on CPU 120, which in turn leads to better performance of controller 110.
機(jī)譯：控制設(shè)備110包括定時(shí)器模塊114和中央處理單元（CPU）120并且連接到曲軸位置傳感器102.CPU 120被設(shè)計(jì)成識(shí)別從曲軸位置接收的位置信號(hào)的每個(gè)邊緣上的中斷 傳感器102，并在接收到中斷時(shí)檢測發(fā)動(dòng)機(jī)位置。 CPU 120還基于檢測到的發(fā)動(dòng)機(jī)位置啟動(dòng)點(diǎn)火和噴射。 控制設(shè)備110的特征在于，它停用并基于預(yù)定事件的檢測來激活來自定時(shí)器模塊114的中斷。 特別地，只要檢測到電機(jī)位置，CPU 120就停用來自定時(shí)器模塊114的中斷的產(chǎn)生，并且當(dāng)發(fā)生預(yù)定事件時(shí)，激活由定時(shí)器模塊114產(chǎn)生的中斷的接收。 本發(fā)明導(dǎo)出較少的中斷和較少的CPU 120負(fù)載，這反過來導(dǎo)致控制器110的更好性能。
