Electronic Control Engine Calibration System Based On CCP

As society grows and technology advances,people are increasingly demanding the car, in addition to becoming more intelligent in terms of performance required in addition,many countries have formulated relevant standards in Emission standards.As electronics is regarded as one of the most important method for reducing the exhaust emissions and improving the power performance and economical efficiency,people pay more and more attention to the development and study of engine electronic control technology.Whether the parameters are calibrated well determines the engine’s performance to a great extend.It is essential in the course of developing of the engine.A multifunctional,flexible and convenient calibration software system plays an important role to the development of all the electronically controlled system.Aiming at the overseas authoritative ASAP criterion and the CCP which is multifunctional and canonical inside it,a new calibration system for electronically controlled engine is developed.The system is mainly composed of data processing module,the calibration platform software and communication convert module.In the data processing module,Firstly,we mainly analysed the A21 documen which are based on the ASAP standard, and parsed out the every parameter inside the engine.Secondly,designed a versatile PC calibration platform, which includes three parts that is namely, engineering manager, A2l editor and workspace.It’s easy to read each parameter in the bottom of ECU when we measure the engine parameters by the platform.Also,we can modify the parameters according to the actual situation,and then download to ECU,in oder to fix the parameters of the engine.At the same time,A2l editor can add or remove the engine variables. In the PC and the underlying electronic control unit communications,CCP is used as the communication protocol of ECU and PC machine.At the same time, the scalability and versatility of systme is greatly improved because of CCP’s address-based communications.Also,intelligent calibration system is studied,then intelligent and optimal calibration method is analysed,which plays a basic role in the theory development of calibration system later.
