Development of an engine control unit: Implementation of the architecture of tasks

Electronic devices in automotive area have been used on large scale and a control unit is mandatory for greater engine efficiency. By performing the spark advance and injection timing correctly in internal-combustion engines, an engine control unit improves drivability and helps to reduce fuel consumption. This paper presents an automotive engine control unit development considering the architecture of tasks. Flowcharts for the algorithms are proposed. The results can be used for an electronic control unit firmware development, also, experimental results using a microcontroller and a JimStim board are presented to validate the theoretical approach.
