AC #2030 – 采埃孚对抗晕车问题，起亚的分离声区技术，氢燃料突破？

大家好，我是约翰•麦克罗伊，欢迎收看Autoline 中国，我们的节目将为您呈现汽车领域最重要最前沿的行业新技术。

采埃孚对抗晕车问题
有人担心乘坐自动驾驶汽车的人会因为对车辆移动更敏感而晕车。这就是为什么供应商采埃孚已经创建了一个防止晕车发生的解决方案。它采用电液控制的阻尼器使车辆尽可能保持水平。该系统连接着汽车上的摄像头和传感器，因此可以提前检测道路瑕疵。每个车轮都单独控制，以确保乘客尽可能少得感觉到颠簸。车辆收集的道路数据也可以发送到云端，并分发到道路上的其他连接车辆。

通用汽车的动态燃油管理系统
有关通用汽车在新款雪佛兰索罗德和GMC西亚皮卡上提供的动态燃油管理系统，我们已经获得了更多信息。他们称之为DFM，是一种汽缸停用系统。它是5.3升V8发动机的标准配置，配备8速自动变速箱，而不是6速。DFM也配备在10速自动变速箱的6.2升V8发动机上。与先前可用的主动燃油管理系统（AFM）不同，DFM可以使发动机仅在2个气缸上运行，并且可根据发动机负载在任何气缸组合上运行。该系统主要通过软件运行，由于需要停用升降机和电子操作的油电磁阀，因此该系统包含机械部件。在美国EPA测试周期中，DFM将这些卡车的燃油经济性提高了5％，这对于并非很大的研究投资来说是一项重大改进。目前通用汽车拥有该技术的独家许可，但并未提及这将持续多久。

接下来…… 供应商麦格纳创造了一种可防止车门被猛烈关闭的新技术。

起亚的分离声区技术
起亚正在展示其分离声区技术的下一代版本。该系统可使车辆中每个乘客在不使用耳机的情况下收听不同的音乐。并且车内没有其他人能听到你在听的内容。这种扬声器具有减少或增加音频声波的技术，这可消除每个座椅中听到的声音重叠，类似于噪音消除系统。这不仅适合公路旅行的家庭，而且也是乘坐共享的一个很好的功能，这样乘客就可以听到他/她想要听的任何东西。起亚表示，该功能距离在车上实现还有一到两年的时间。

麦格纳的智能技术
供应商公司Magna刚刚推出了一项使乘客更容易上车的新技术。它被称为SmartAccess，您可以通过按下按钮或挥动您的手来打开车门。即使在风吹过时，动力门也能够保持在原位不会关上。 它还具有障碍物检测功能，可防止门撞击人或物体。另一个优点是SmartAccess消除了对门把手的需求，为设计师提供了更多的造型自由。

接下来…… 一项新技术可能对电动汽车构成威胁。

氢燃料突破？
澳大利亚联邦科学与工业研究组织（CSIRO）表示，他们在制氢方面取得了突破性进展。他们使用易于运输的液氨，然后使用具有独特膜的模块化单元将氢气与氨气分离。

请注意，氨的化学成分是NH3，因此每个分子的氢含量高于水（H2O）。

模块化单元可以在加油站或其附近使用，因此您可以在现场制氢。与氢气不同，氨易于运输或输送。这一突破可以真正利于打开燃料电池汽车市场。它可能对电动汽车中使用的电池构成真正的威胁。

Hello, I’m John McElroy, welcome to Autoline China, the show that covers some of the most important new technologies in the automotive industry.

ZF FIGHTS MOTION SICKNESS
There’s a concern that people who ride in autonomous vehicles will experience motion sickness because they’re more aware of vehicle movement. That’s why the supplier ZF has created a solution to prevent it from happening. It uses electro-hydraulically controlled dampers to keep the vehicle as level and as still as possible. The system is connected to cameras and sensors on the car, so it can detect road imperfections ahead of time. And each wheel is individually controlled to make sure the passengers feel as little as possible. The road data the vehicle collects can also be sent to the cloud and distributed to other connected vehicles on the road.

GM’S DYNAMIC FUEL MANAGEMENT SYSTEM
We’ve got more information on the Dynamic Fuel Management system that General Motors is offering on the new Chevrolet Silverado and GMC Sierra pickups. DFM, as they call it, is a cylinder deactivation system. It’s standard on the 5.3 liter V8 engine with the 8-speed automatic transmission, not the 6-speed. And it’s on the 6.2 liter V8 with the 10-speed automatic transmission. Unlike the Active Fuel Management system, or AFM, that was available previously, DFM can have the engine running on only 2 cylinders. And it can operate on any combination of cylinders depending on engine load. The system primarily operates via software, but requires deactivation lifters and electronically operated oil solenoids, so there are mechanical components. DFM improves the fuel economy of these trucks by 5% on the United States EPA test cycle, which is a significant improvement for not a lot of investment. General Motors has an exclusive license on the technology, but will not say for how long.

Still to come…the supplier Magna creates new technology that stops car doors from being slammed shut.

KIA’S SEPARATED SOUND ZONE TECHNOLOGY
Kia is showing off the next-gen version of its Separated Sound Zone technology. The system allows each passenger in the vehicle to listen to different music without using headphones. And no one else in the car can hear what you’re listening to. The speakers feature technology that reduces or increases audio sound waves, which negates the overlapping of sounds heard in each seats, similar to noise cancellation systems. Not only is this perfect for families on a road trip but it’s also a great feature for ride sharing, so a passenger can listen to whatever he or she wants. Kia says the feature is another one or two years away before it will show up in its vehicles.

MAGNA’S SMARTACCESS TECHNOLOGY
The supplier company Magna just introduced new technology that makes it easier to get in your car. Called SmartAccess, it allows you to open car doors with a push of the button or just by waving your hand. The powered doors are able to stay in place even when the wind blows and won’t slam shut. It also features obstacle detection that prevents the door from hitting people or objects. Another benefit is SmartAccess eliminates the need for door handles, which gives designers more styling freedom.

Coming up next…a new technology could be a threat to battery electric cars.

HYDROGEN FUEL BREAKTHROUGH?
Australia’s Commonwealth Scientific and Industrial Research Organization or CSIRO, says it’s developed a breakthrough in making hydrogen. It uses liquid ammonia which can easily be shipped and then uses a modular unit with a unique membrane to separate the hydrogen from the ammonia.

Remember, the chemical composition of ammonia is NH3, so each molecule has more hydrogen than water, or H2O.

The modular units can be used at or near a refueling station, so you can make hydrogen on-site. Unlike hydrogen, ammonia can easily be shipped or piped, and this breakthrough could really help open the market for fuel cell cars. And it could be a real threat to the batteries used in electric cars.

And with that we wrap up this edition of Autoline China, thanks for watching and please join us again next time.
