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。
丰田开发新磁铁
用于电动机的磁体必须能够在高温下保持磁化。稀土金属能够帮助加热,这就是为什么高达30%的磁铁使用的元素是稀土。然而,这些元素可能会很昂贵。而且,中国在这些稀土材料市场上占主导地位。2010年,日本汽车制造商认为中国正在阻止他们获得他们所需的稀土材料。这也就是丰田开发一种不使用稀土的新磁体的主要原因,也是钕的需求量高达50%的一个重要原因。磁体将首先用于电动助力转向电机。在接下来的10年里,该公司将致力于在电动汽车中使用磁铁。
避免脏空气
我们已经看到各大城市都考虑禁止内燃机作为减少污染的一种方式,但在内燃机汽车被禁止或电动汽车替代其之前,高度拥挤的地区将继续存在空气质量问题。现在供应商海拉正与BreezoMeter公司合作,BreezoMeter公司提供实时的空气质量数据,以便司机了解空气在他们周围的肮脏程度。如果某个区域特别恶劣,系统会向司机发出警告,甚至提供一条镇内污染较少的备用路线。或者,在汽车启动之前,可以将最干净的路线编程到导航系统中。
接下来继续……大陆集团开发可检测路况的轮胎。
CONTINENTAL的概念轮胎
美国大陆航空集团展示了几款可适应不同路况的概念轮胎,称为ContiSense和ContiAdapt。它们使用传感器来监测花纹深度和温度,通过导电橡胶将信号发送到车内的接收器。它可以提醒司机轮胎是否过度充气或充气不足,并警告爆胎。将来,传感器将能够检测道路状况。车轮中的微型压缩机和可变宽度的轮辋将改变轮胎的压力并调整接触面的尺寸以满足任何路况条件的需要。用于低滚动阻力的高压和小接触面可以转变为用于湿滑路面的低压和大接触面。
DENSO 开发新视觉传感器
供应商Denso开发了一种新型视觉传感器,可在夜间驾驶时提高安全性。它采用专为弱光使用而设计的特殊镜头和固态成像设备,以帮助检测其他道路使用者,行人和标志。这使得自动紧急制动在夜间能展现更好的性能。日本电装的传感器可以在新的丰田Alphard和Vellfire货车上使用,这些货车主要在日本销售。
接下来我们将探讨,为什么越来越多的汽车制造商对开发无人驾驶飞机产生兴趣。
越来越多的汽车制造商对客运无人机有兴趣
乘客无人机可能是交通不便地区的终极解决方案。你可以飞过去。这个概念是想让无人机成为电动并且是自动的,这样可以使无人机保持安静,并且免去乘员需要驾驶员执照的麻烦。
目前保时捷刚刚宣布有兴趣开发自己的无人驾驶飞机。其实保时捷并非唯一感兴趣的汽车制造商。戴姆勒投资了一家名为Volocoptor的德国无人机公司。中国汽车制造商吉利收购了美国无人机公司特拉弗吉亚。 而大众汽车旗下的Ital Design也正在设计一架搭载空客的无人驾驶飞机。
这些无人机的第一次测试将在大约两年后开始,预计大约十年后它们将变得非常普遍。这就是为什么越来越多的汽车制造商对此开始感兴趣。
那今天的节目到这里就结束了。感谢您收看Autoline中国。
Hello, I’m John McElroy, welcome to Autoline China, the show that covers some of the most important new technologies in the automotive industry.
TOYOTA DEVELOPS NEW MAGNETS
The magnets used in electric motors must be able to maintain magnetization at high temperatures. Rare earth metals are able to help with heat and that’s why up to 30% of the elements used in magnets are rare earths. However, these elements can be expensive Also, China dominates the market for these materials. In 2010 Japanese automakers felt that China was preventing them from getting the rare earth materials they needed. That’s a key reason why Toyota developed a new magnet that does not use some rare earths and also the amount neodymium needed by up to 50%. The magnets will first be used in electric power steering motors. And within the next 10 years, the company is aiming to use the magnets in electric vehicles.
AVOIDING DIRTY AIR
We’ve seen major cities consider banning internal combustion engines as a way to reduce pollution, but until they are banned or when EVs take over, highly congested areas will continue to have air quality problems. Now supplier Hella is teaming up with BreezeoMeter, a company that provides real-time air quality data, to keep drivers aware of how dirty the air is around them. If an area is particularly bad, the system sends a warning to the driver and even provides an alternate route through a less polluted part of town. Or the cleanest route can be programmed into the navigation system before the car ever takes off.
Still to come…Continental develops tires that can detect road conditions.
CONTINENTAL’S CONCEPT TIRES
Continental is showing off a couple of concept tires that can adapt to different conditions. Called ContiSense and ContiAdapt they use sensors to monitor tread depth and temperature, which sends signals through electrically conductive rubber to a receiver in the car. It can alert drivers to over- or under-inflation, and can warn of a puncture. In the future, the sensors will be able to detect road conditions. Micro-compressors in the wheel and a variable-width rim will change the pressure of the tire and adjust the size of the contact patch to meet the needs of any condition. High pressure and a small contact patch for low-rolling resistance can change to low pressure and a large contact patch for slippery roads.
DENSO DEVELOPS NEW VISION SENSOR
The supplier company Denso has developed a new vision sensor that improves safety while driving at night. It uses a unique lens designed for low-light use and a solid-state imaging device to help detect other road users, pedestrians and signs. This allows automatic emergency braking to perform better at night. Denso’s sensor is available on the new Toyota Alphard and Vellfire vans, which are primarily sold in Japan.
Coming up next…why more and more automakers are interested in developing passenger drones.
MORE AUTOMAKERS INTERESTED IN PASSENGER DRONES
Passenger drones could be the ultimate solution to areas with bad traffic. You could fly right over it. The idea is to make these drones electric so they’re quiet, and autonomous so you don’t need a pilot’s license.
Now Porsche just announced it’s interested in developing its own passenger drone. And it’s not the only automaker. Daimler invested in a German drone company called Volocoptor. The Chinese automaker Geely bought the American drone company Terrafugia. And Ital Design, which is owned by Volkswagen, is designing a passenger drone with Airbus.
The first tests of these drones will start in about two years and they’re expected to become quite common in about a decade. And that’s why more and more automakers are starting to get interested.
But that wraps up today’s report, thanks for watching Autoline China.
