Engine electronic control unit (ECU) receives the signals from the sensors, and gets the current engine status. Then depending on the signals, the ECU calculates fuel injection rate, injection timing and quantity. Accordingly the actuators which are driven by ECU carry out the better fuel control. Whether the vehicle could work efficiently and reliably almost dependents on the engine ECU is normal or not. One way to test engine ECU is using load box which can diagnose and calibrate the faults. This paper chooses CAN bus to realize the communication between ECU and load box because of its widely using and well function. This paper formulates the CAN bus communication protocol which meets the needs of load box test, and designs the CAN communication module and signal input /output module. MPC5633 made by Free scale is used as the micro controller unit (MCU) in ECU. Through the experiments showed in paper proves the testing programs of ECU control can realize the function requirements.","PeriodicalId":368130,"journal":{"name":"2011 Fourth International Conference on Intelligent Computation Technology and Automation","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128395372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With this as the object, optimal tool orientation planning methods for five-axis machining of blisk are studied in this paper. Machining processes and tool path generation methods are first presented according to the structural characteristics of the blisk. Then the feasible region of tool orientation for planned CC point is determined by partitioning the unit sphere formed by all possible tool axis vectors and interference checking. Based on the simplified feasible region, constrained optimization method is used to get optimal tool orientations along the tool path.
