交通堵塞、交通事故和尾氣排放問題，都是人們的心頭大患，因此汽車行業(yè)面臨的一大隱性挑戰(zhàn)就是如何為全社會開發(fā)合適的技術(shù)，并加以應(yīng)用。
數(shù)據(jù)表明，2013年洛杉磯的駕駛員平均在交通擁堵中所花費(fèi)的時(shí)間為90小時(shí)。同年，美國因交通事故死亡的人數(shù)為3.3萬人，而甚至連尾氣排放都能導(dǎo)致死亡。
“這個(gè)數(shù)據(jù)讓我很震驚：從全球來看，道路交通污染直接導(dǎo)致5.3了的萬人死亡，大多數(shù)是尾氣煙塵造成的，”大陸公司執(zhí)行董事HelmutMatschi表示。“這個(gè)數(shù)字非常高，會讓我們懷疑繼續(xù)生產(chǎn)汽車是否還有意義？但答案顯然是肯定的。”
在底特律科博會展中心的AVL劇場，也就是2015SAE全球年會的會場，Matschi是周二早上的主題演講嘉賓。
汽車互聯(lián)技術(shù)有助于降低事故率，減少交通擁堵，并降低排放。
“過去的汽車無法通過互聯(lián)網(wǎng)相連，而今天，越來越多的汽車可以聯(lián)網(wǎng)。未來的汽車將會成為萬物互聯(lián)網(wǎng)絡(luò)（IoE）的一部分，” Matschi說。
大陸汽車集團(tuán)電子地平線（eHorizon）戰(zhàn)略的下一步計(jì)劃，就是基于IoE概念進(jìn)行研發(fā)。
目前所生產(chǎn)的eHorizon平臺主要依賴于傳感器和地圖數(shù)據(jù)，于2012年首次推出。eHorizon的客戶之一為商用卡車制造商Scania。使用其車輛的車隊(duì)運(yùn)營商通過使用這一產(chǎn)品，可以提早對下一段行駛路線中發(fā)生的變化做出調(diào)整。該系統(tǒng)的一個(gè)主要優(yōu)勢就是可以幫助用戶降低燃油消耗。
“這個(gè)系統(tǒng)已經(jīng)幫助我們節(jié)約了3%的燃油。借助（基于傳感器的）靜態(tài)eHorizon平臺，我們至今已經(jīng)節(jié)約了2300萬加侖柴油，相當(dāng)于實(shí)現(xiàn)了239噸二氧化碳的減排成果，” Matschi稱。今年晚些時(shí)候，將會有另外4家重型卡車的OEM在其生產(chǎn)的車輛上使用大陸汽車的eHorizon。
大陸汽車新推出的Dynamic eHorizon是一個(gè)基于云平臺的產(chǎn)品。大陸汽車與IBM、思科和位置云公司Here聯(lián)手開發(fā)，將數(shù)字地圖變成了一個(gè)高度精準(zhǔn)、實(shí)時(shí)更新的信息載體。
“做到了這一點(diǎn)，我們就能在安全度、舒適度和排放這些方面實(shí)現(xiàn)很多提升，” Matschi表示。DynamiceHorizon還支持其他科技，包括駕駛員輔助系統(tǒng)、導(dǎo)航系統(tǒng)和增強(qiáng)現(xiàn)實(shí)平視顯示器等。
但這些先進(jìn)技術(shù)都會增加軟件的復(fù)雜程度。
“軟件的需求越來越高，” Matschi指出，一輛常見的豪華車可能裝有160個(gè)以上傳感器、多達(dá)100個(gè)ECU、以及170多個(gè)的執(zhí)行器。“再加上未來車間互聯(lián)的可能性，不同電子元件之間的信息通訊還將更加密切。”
通過行業(yè)合作，我們可以實(shí)現(xiàn)這一目標(biāo)。
“如果我們能夠像現(xiàn)在這一齊心協(xié)力，提升駕駛的舒適度和安全性，并減少二氧化碳排放，那么汽車還將會在未來的道路上繼續(xù)行駛。” Matschi說。

Continental's Matschi: mobility is changing
Traffic gridlock, accident fatalities, and vehicle emissions are not good things. So the underlying challenge for the auto industry is to develop and use technologies appropriately for society.
Data shows that in 2013, Los Angeles drivers spent 90 hours stuck in traffic. That same year there were 33,000 fatalities on U.S roads. Even vehicle emissions caused death.
“This was really for me a surprising (statistic): Globally, 53,000 fatalities were directly attributed to road traffic pollution, mostly because of exhaust fumes," said Helmut Matschi, Executive Board Member at Continental. "That’s a real high number. So that could lead to the question: Does it really make sense to work further on cars? But clearly for us the answer is yes.”
Matschi was the Thursday morning keynote speaker in the AVL theater inside Detroit’s Cobo Center at the 2015 SAE World Congress.
A connected vehicle could help reduce accidents, traffic congestion, and emissions.
“In the past, vehicles had no access to the Internet. Today, more and more vehicles have Internet access. Tomorrow, the vehicle will be part of the Internet of Everything (IoE),” according to Matschi.
The next evolution of Continental's electronic Horizon (eHorizon) strategy underscores the concept of IoE.
The current production version of eHorizon relies on sensors and map data. Launched in 2012, fleet operators using Scania commercial trucks can adjust to changes in an upcoming route early. A major benefit is reduced fuel consumption.
“This has already saved three percent of fuel. With that static (sensor-based) eHorizon, we have up to now saved 23 million gallons of diesel. When we convert this into CO2, that’s an equivalent of 239 tons,” said Matschi. Continental’s eHorizon will be used by four other heavy-duty truck OEMs later this year.
Continental’s new Dynamic eHorizon is cloud-based. In collaboration with IBM,Cisco, and the location cloud company Here, it turns the digital map into a highly precise and up-to-date information carrier.
“With that we can enhance a lot of activities on the safety side, on the comfort side, (and) emissions side,” said Matschi. Dynamic eHorizon also supports other technologies, including driver-assistance systems, navigation systems, and augmented-reality head-up displays.
All of these various advanced technologies add software complexity.
“The software demand is increasing and increasing,” said Matschi, noting that a typical luxury vehicle can have more than 160 sensors, up to 100 ECUs, and more than 170 actuators. “And with the possibility of connectivity there is even more interest that different electronics communicate with each other.”
Industry partnerships can bring it all together.
“In order to enhance the driving comfort, to have safer driving, and to reduce CO2, if we stick together as an industry--as we do--then we are ready for vehicles, which are always on for future mobility,” said Matschi.
