而每一款汽車的設計作為一個系統(tǒng)的工程，是相對獨立的過程，很多跨國汽車公司早在幾十年前就已經(jīng)打破了這種相對的獨立，將設計的每一個過程凝練提升，形成一個個模塊，按照系統(tǒng)的方法組織起來，定義為汽車設計流程。在以后的新車設計中，將每一個過程融入了這種既定的設計模式，按部就班地推進，控制著汽車的每一個非常詳細的設計過程，從而順利高效地完成設計。在國內(nèi)，一汽、二汽、上汽等大的汽車企業(yè)集團都已經(jīng)建立起了比較完善的產(chǎn)品設計流程，在國內(nèi)愈演愈烈的汽車產(chǎn)品競爭中，這些企業(yè)的產(chǎn)品競爭力有著明顯的優(yōu)勢，產(chǎn)品更新速度快，質(zhì)量可靠，深得用戶的信賴，可見研發(fā)流程的建立對企業(yè)的重要意義。伴隨著汽車車身造型的設計與修改要求日趨增高，參數(shù)化設計更符合和貼近現(xiàn)代CAD中的概念設計和并行設計思想，并可提高設計與分析的柔性，因此車身模型的參數(shù)化設計經(jīng)成為車輛制造行業(yè)發(fā)展的必然趨勢。參數(shù)化設計是以一種全新的思維方式來進行產(chǎn)品的創(chuàng)和修改設計的方法。目前傳統(tǒng)的手工造型方法已被建立在各種先進的造型建模軟件基礎上的計算機輔助造型方法所取代，參數(shù)化設計技術能夠快速吸收國外汽車車身設計的先進技術，快速響應市場，提高我國自主設計開發(fā)汽車的能力，提高汽車產(chǎn)品競爭能力。隨著汽車技術的發(fā)展，汽車的舒適性不斷提高以滿足人們的要求。汽車車門是車上相對獨立的總成，車門設計不但關系到汽車的實用性，對汽車也有很大的裝飾作用。因此車門的設計也越來越講究，而且使用越來越多的網(wǎng)絡和電控技術。從1957年新中國的第一輛汽車正式生產(chǎn)下線，中國汽車在20世紀中期經(jīng)歷了漫長的緩慢發(fā)展階段，在經(jīng)過2003年和2006年的兩輪爆發(fā)式增長后，開始步入平穩(wěn)增長階段。2009年嚴峻的宏觀經(jīng)濟形勢下，中國汽車行業(yè)的發(fā)展面臨著前所未有的挑戰(zhàn)與機遇，同時也受到來自各個方面的沖擊。中國要想從汽車制造大國發(fā)展成為汽車產(chǎn)業(yè)強國，就必須在汽車產(chǎn)品的研發(fā)上取得突破。歐美日的汽車企業(yè)之所以能夠如此強勢，與他們幾十年甚至上百年的技術革新與經(jīng)驗積累是分不開的，翻開他們汽車產(chǎn)業(yè)發(fā)展的歷史，我們都能夠清晰的感受到他們相同的企業(yè)發(fā)展脈
