阅读:706发布:2020-12-08

专利汇可以提供Controller for vehicle专利检索,专利查询,专利分析的服务。并且PURPOSE: To prevent complexity of a program and obtain a high speed process by dividing a data processing unit into a data processing section for calculating an output value and an event processing section for judging flow of the data process, and making both processes by means of individual processors at the same time.
CONSTITUTION: A multi CPU system is composed of a CPU 3 for event processing, a CPU 4 for calculation process, a CPU 5 for input/output processing. An air quantity sensor signal, and an oxygen sensor signal are inputted by the CPU 5 for the input/output processing and also a crank angle sensor signal via an I/O circuit 9, and then each data is inputted in a common memory 7 after processing and the output value subjected to secondary processing through the calculation process is read from the common sensor 7 and outputted to an injector or the like. A specified input data is read in the CPU 4 for the calculation process, and an output value for control is calculated by the calculation process, so as to store it in the common memory 7. Furthermore, the specified data and time data are read in the CPU 3 for the event process, and a flag data is calculated by the calculation process so as to store it in the common memory 7.
