【摘要】：靈活燃料發(fā)動機作為新能源汽車的一種,目前正在全球普及,以巴西及北美應(yīng)用最為廣泛,普通的汽油發(fā)動機經(jīng)過電子控制系統(tǒng)的重新設(shè)計匹配就可以作為靈活燃料發(fā)動機使用,因此靈活燃料發(fā)動機電子控制系統(tǒng)的開發(fā)匹配成為靈活燃料汽車開發(fā)的首要任務(wù)。 相比于傳統(tǒng)汽油機電子控制系統(tǒng),靈活燃料發(fā)動機電子控制系統(tǒng)更加復(fù)雜,主要表現(xiàn)在發(fā)動機ECU需要自行學習目前汽車油箱中燃料的乙醇含量,并由此確定發(fā)動機的運轉(zhuǎn)參數(shù)。不同的燃料,發(fā)動機工作的各個參數(shù),如點火角、充氣效率、噴油量等也隨之不同,這就決定了發(fā)動機控制軟件需要標定的參數(shù)至少是傳統(tǒng)汽油機的兩倍以上,工作量也隨之增加一倍。 傳統(tǒng)的汽油發(fā)動機電子控制系統(tǒng)開發(fā)需要約12個月時間,開發(fā)費用依據(jù)設(shè)計變更的多少基本在400-500萬人民幣之間。項目目標既有客戶的要求,同時還有國家法規(guī)的強制要求,可以說開發(fā)難度很大,對于一些性能的要求帶有強制性,例如尾氣排放污染物控制性能,沒有任何緩沖的余地。 出于汽車市場發(fā)展的需求和技術(shù)進步的要求,整車制造企業(yè)給予各類車型的開發(fā)時間大致相同,不會因為一個單獨功能模塊的復(fù)雜而延長整個車型的開發(fā)時間,這就使得靈活燃料類發(fā)動機電子控制系統(tǒng)的開發(fā)時間被限制為同傳統(tǒng)汽油發(fā)動機電子控制系統(tǒng)開發(fā)一樣的12個月,同樣的時間內(nèi)完成兩倍以上的工作量,造成開發(fā)任務(wù)非常繁重,開發(fā)工作的進行不能有任何的延遲。由于開發(fā)工作量的增加,研發(fā)費用為1000萬人民幣左右。 靈活燃料發(fā)動機控制系統(tǒng)相比傳統(tǒng)汽油機電子控制系統(tǒng)的復(fù)雜性,決定了其項目管理的復(fù)雜性,需要協(xié)調(diào)更多的資源,同時需要更多并行使用資源的計劃出現(xiàn)。相比與傳統(tǒng)的汽油發(fā)動機電子控制系統(tǒng)開發(fā),在同樣的時間內(nèi),完成兩倍的開發(fā)工作量,是一個巨大的挑戰(zhàn)。而高昂的開發(fā)費用即帶來了良好的企業(yè)收益也帶來了巨大的潛在風險,一旦項目開發(fā)失敗,對于供應(yīng)商和客戶來說,企業(yè)的損失都是巨大的。如何把項目管理的理論良好的運用在該類開發(fā)項目中,控制費用,節(jié)約成本,降低風險,提高開發(fā)質(zhì)量成為一個難題,這也本文研究的主要方向。 本文針對國內(nèi)某整車企業(yè)的靈活燃料汽車電子控制系統(tǒng)開發(fā)進行項目管理的研究,綜合利用項目管理理論,對如何按時按質(zhì)的完成該類項目進行研究。著重研究項目計劃的制定,以期為類似項目的開發(fā)提供參考依據(jù)。
[Abstract]:Flexible fuel engines, as one of the new energy vehicles, are now gaining popularity in the world, with Brazil and North America being the most widely used vehicles. Ordinary gasoline engine can be used as a flexible fuel engine by redesigning and matching with electronic control system, so the development and matching of electronic control system of flexible fuel engine becomes the most important task in the development of flexible fuel vehicle. Compared with the traditional electronic control system of gasoline engine, the electronic control system of flexible fuel engine is more complex. The main manifestation of this system is that the engine ECU needs to learn the ethanol content of the fuel in the fuel tank and determine the engine operating parameters. Different fuel, various parameters of engine work, such as ignition angle, inflatable efficiency, fuel injection amount, etc., which determines that the engine control software needs to calibrate at least twice as many parameters as the traditional gasoline engine. The workload doubled. It takes about 12 months to develop the traditional electronic control system of gasoline engine, and the development cost is between 4 million and 5 million RMB according to the design change. The goal of the project has not only the requirements of customers, but also the mandatory requirements of national laws and regulations. It can be said that the development is very difficult, and some performance requirements are mandatory, such as the emission control performance of exhaust gas, there is no room for buffering. In view of the demand of the development of the automobile market and the requirements of technological progress, the development time given to all kinds of models by the whole vehicle manufacturing enterprise is roughly the same, and the development time of the entire vehicle model will not be prolonged because of the complexity of a single functional module. This limits the development time of the flexible fuel engine electronic control system to the same 12 months as the traditional gasoline engine electronic control system development, with more than twice the amount of work done in the same time. The development task is very heavy, and there can be no delay in the development work. As a result of the development workload increases, the research and development expense is about 10 million RMB. Compared with the traditional electronic control system of gasoline engine, the complexity of flexible fuel engine control system determines the complexity of project management. Compared with the traditional gasoline engine electronic control system development, in the same time, to complete twice the development workload, is a huge challenge. And the high development cost not only brings the good enterprise income but also brings the huge potential risk. Once the project development fails, for the supplier and the customer, the enterprise's loss is enormous. How to apply the theory of project management to this kind of development project, to control the cost, to save the cost, to reduce the risk and to improve the quality of the development becomes a difficult problem, which is also the main research direction of this paper. In this paper, the project management of the flexible fuel vehicle electronic control system in a domestic vehicle enterprise is studied, and how to finish the project on time and according to the quality is studied by using the project management theory. Study the project plan in order to provide reference for the development of similar projects.
