用線控駕駛的感覺

　　當(dāng)你進(jìn)入汽車時，你知道該期待什么。將有一個方向盤，你可以改變車輛的方向，一個齒輪桿設(shè)置齒輪，和兩個或三個踏板在地板上，你按加速和制動的汽車，并在模型與手動變速器，脫開離合器，以便您可以改變齒輪。停車制動器通常位于前排座椅之間的地板上，有助于確保車輛靜止。它不必是這樣：一些最早的汽車有加速器踏板，你側(cè)身移動，這使許多有意義的顛簸的道路上的時間。那么，為什么大多數(shù)汽車的設(shè)計模式已經(jīng)持續(xù)了一百年或更長時間呢？

　　一個顯而易見的解釋是互操作性。作為汽車控制布局的標(biāo)準(zhǔn)模式出現(xiàn)，已經(jīng)熟悉這一模式的客戶在下一輛車上堅持使用它。第二個原因更為微妙。標(biāo)準(zhǔn)控制布局的許多元素出現(xiàn)是因為它們是使機(jī)械連接變?yōu)殛P(guān)鍵機(jī)構(gòu)的物理力所必需的最簡單的機(jī)械連接方式。想一個齒輪齒條式轉(zhuǎn)向系統(tǒng)，使駕駛員手搖汽車進(jìn)入右前輪位置，或物理節(jié)流機(jī)構(gòu)連接油門踏板的蝶閥化油器。

　　As automobiles have become more complex and demands for comfort and safety have increased， the driver’s role in directly controlling the underlying workings of a vehicle have become increasingly mediated by other mechanisms. Human muscle power has been amplified by hydraulic systems to ease steering and braking; engines have become closely managed for greater efficiency and lower emissions by complex electronic systems; and even the driver’s driving intent， expressed as the angle of the steering wheel and the set of the accelerator， have been mediated by vehicle stability control and similar systems that stop the driver pushing the vehicle beyond its dynamic limits. You may think you are in the driver’s seat， but， in fact， you are in a partnership with complex systems that express a set of decisions made by automobile engineers in R&D labs miles away and years ago.
