2010年，標致使用SR1概念車向公眾展示了它全新的i-Cockpit觸屏系統(tǒng)，該系統(tǒng)可對加熱、通風、導航、音響、網(wǎng)絡連接和路線計算等功能進行控制。第一代系統(tǒng)于2012年正式用于量產車型標致208，而在2015年法蘭克福車展上，標致在Fractal 電動城市轎跑概念車中展示了新一代i-Cockpit系統(tǒng)，而這次的重點在于聲音。
這輛車擁有專屬的“聲音簽名”——是由DJ兼聲音設計師Amon Tobin創(chuàng)造的。當駕駛員用智能手表遠程鎖定系統(tǒng)開啟車輛時，該系統(tǒng)會自動啟動。“電動汽車不是什么新概念，但它有一個問題，那就是它不發(fā)聲，”標致概念車與高級系統(tǒng)主任Matthias Hossann解釋道。
“在法國，如果你說你駕駛的是電動汽車，有的人還會為你可惜，因為他們認為駕駛起來不夠刺激。我們思考了一下這個問題，覺得駕駛電動汽車的確會因為沒有聲音而缺乏一定樂趣。我自己也深有感受，因為就連啟動的時候，你都不知道是不是真的發(fā)動了。”
標致的設計團隊認為，聲音是傳統(tǒng)駕駛體驗的一部分，可以告訴駕駛員速度等信息。“我們認為，通過開發(fā)出某些特定的聲音，我們可以喚起相應的情感、駕駛樂趣，并提高駕駛的精確度，” Hossann表示。
因此，標致為Fractal專門開發(fā)了一些聲音。“GPS是一個很好的例子，” Hossann繼續(xù)說道。很多人都曾體驗過在一條擁擠的道路上錯過轉彎的問題，盡管導航系統(tǒng)的確給出了提示，但這一問題仍有可能發(fā)生。為解決這一問題，F(xiàn)ractal的設計師們使用了方向聲音技術。“我們認為可以讓某些聲音從一個方向（比如右邊）傳過來，提醒駕駛員在300米后向右轉，再加上另外一些從右邊來的聲音，這樣駕駛體驗會更好。”
標致設計團隊從項目一開始就和Tobin合作了。“我們與他分享了設計流程，并討論了工藝、材料、形狀和聲音等問題，”其中包括轉向提示音和警告音等功能性聲音，Hossann表示。
除了展示電動汽車上可以使用某些功能性聲音這一理念之外，這個項目還有一個更實際的用途。歐盟規(guī)定，2019年起賣出的所有電動汽車都必須在速度到達30 km/h (19 mph)的時候發(fā)出警告行人的聲音。
標致團隊認為這是一個為標致電動車開發(fā)一套專用聲音效果的機會。不僅如此，F(xiàn)ractal的設計團隊還將購車人的其他價值評判標準也考慮在內，如關門聲的質量。“這也是我們?yōu)槭裁丛谶@輛車上專門開發(fā)了開關門的聲音，” Hossann表示。
設計師們還考慮到了車輛的個性化需求。“現(xiàn)在的車輛個性化主要是增加些標貼或車身用漆之類的東西。而在未來，你甚至可以像手機一樣使用自己的聲音，如開門聲。”
聲音還被用于車內設計的檢測。“最好的艙內形狀應該是不會產生回聲的。我們并不是畫幾根線，看上去對就行了，我們采用的是參數(shù)設計方法。” Hossann。“我們通過特定算法來定義形狀，這是一種思考事物的新方法。而且這個形狀是無法通過沖壓，碳纖維或注射制模等工藝制成的。”
Hossann指著車門板介紹道：“這就是為什么我們使用大量3D打印技術的原因。車內80%的內飾是用3D打印方法制造出來的。當然因為這是一輛概念車，所以才能這么做，但我們的確相信這個技術會改變未來的汽車行業(yè)。”
“在目前這個階段，我們還很難預測3D打印的生產速度和產量，” Hossann表示，“但對于像裝飾品一類的小東西來說，你可以想象，未來消費者如果希望在某個地方增加點裝飾，那么他就可以去經銷商那里打印出來并裝在車上。
“我們像傳統(tǒng)設計師一樣設計這輛車，但我們幾乎設計了整個思考方式。我們對思考事物和研發(fā)的方法進行了一番大討論。在一輛傳統(tǒng)的汽車上，為了達到一定的隔音效果，就必須在門板上加點泡沫。而在未來，我們可以設計出效率更高的車身形狀，這樣就不用添加隔音材料，還能起到減重的效果。”

Peugeot Fractal demonstrates a new take on sound design
Peugeot used the 2010 SR1 concept to introduce its i-Cockpit touchscreen-based system, designed to control heating and ventilation, navigation, audio, connectivity, and the trip computer. The first-gen system entered production in the 2012 Peugeot 208. The company took the i-Cockpit concept one stage further in the Fractal electric urban coupe concept at the 2015 IAA Frankfurt Show, to include sound.
The concept plays a “sound signature”, created by DJ and sound designer Amon Tobin, which is triggered when the driver opens the car using the smart watch remote locking system. “Behind this concept of an electric car—that is not really new, there was this question that electric cars emit no sound”, explains Matthias Hossann, Head of Concept Cars and Advanced Design at Peugeot.
“In France, sometimes if you say you are driving an electric car, people say they are very sorry for you because they think it is not as exciting to drive an electric car. We thought about that and agree that you lack some pleasure with an electric car because it emits no sound. I have had this experience because even when you start an electric car, you don’t know that it has started.”
The Peugeot design team’s thinking was that sound is part of the conventional driving experience, giving the driver an indication of speed, for instance. “We think that by developing some specific sounds, we can generate some specific emotions, some specific driving pleasure and also a more precise driving experience”, explains Hossann.
As a result, Peugeot has developed some more specialized sounds for the Fractal. “The best example is the GPS," continued Hossann. Most of us have had the experience on a busy road of missing a turn even though the navigation system has given the instruction. The Fractal designers have used directional sound to help. “We think that by developing some sounds that come from one side, for example the right, with a command to turn right in 300 m, followed by some other sound from the right, will give a better driving experience.”
The Peugeot design team has worked with Tobin since the beginning of the project to design specific sounds. “We have shared the design process with him, we have discussed process, material, shape, and sound,” said Hossann. All the functional sounds such as the turning indicators and warning sounds.
As well as presenting the possibility of designing an EV with specific functional sounds, there could be a practical application. All electric cars sold in the European Union from 2019 will be required to make a sound at speeds up to 30 km/h (19 mph) to warn pedestrians of their presence.
The Peugeot team thinks this could be an opportunity to develop a specific sound signature for Peugeot electric cars. In addition, the Fractal design team has tapped into other value judgments that car buyers make about cars, such as the quality of the sound of the door when it closes. “That is why, for example on this car we have developed a sound for opening and closing the doors,” said Hossann.
The designers also considered current personalization of cars, “Personalization today is a lot of adding things like stickers and paint. Tomorrow, you could have the same body, but just personalize the sound like a smartphone such as the door opening.”
Sound has also been used to determine interior design features. “The best shape is an anechoic chamber. In fact we work with parametric design. We don’t design just by drawing every line and making it look right,” said Hossann. "We just work with an algorithm. We define a shape—it’s a new way of conceiving things. This shape is impossible to produce by stamping, or with carbon fiber, or injection molding,”
Hossann pointed to the inner door panel: “That’s why we use a lot of 3D printing. More than 80% of the interior of the car is produced by 3D printing. Again this is possible because it is a concept car, but it’s something that we believe could change the car industry in fact.”
“At this stage it’s difficult to have the speed and the volume”, said Hossann, “But for example for small items like some décor, you can imagine in the future a customer might be able to choose a specific area where they can add some specific décor and have this printed at the dealer and fitted to the car.
“We designed the car like a classical designer, but we almost designed the way of thinking about our car. We had a big discussion about the way of thinking about things and developing them. On a classical car you have a door panel, you add some foam to make the car more soundproof inside. Tomorrow we can imagine having an efficient shape for sound so that you don’t need to add soundproofing material, so you can save weight.”
