This paper presents a programming technique for lhe engine control unit using the real lime as. The software of the engine control unit is composed of one ISR and six tasks. In engine control. some tasks must be executed at the very lime when the engine requires. The real lime as plays a role of the scheduler. so enables to change tasks very fast when the system requires. Using the real time as. the convenience of the programing and the efficiency of the usage of CPU have been enhanced.
