聪明的人总是有的!在2002年,有人研究出了“brakeoverridesystem”(中文有人翻译成“刹车优先系统”,其实override在这里不是“优先”,而是“霸道”。更确切的翻译应该是“刹车是爷”。爷来了,孙子们都给我让路!)。这是什么意思呢?就是:只要你踩刹车,不论油门信号是什么,供油系统立刻把油减小到最小,专业词汇叫“怠速”,英文叫idle,就是发动机的转速在你不给油门的时候,小于这个转速,发动机就会死火。大于这个转速,发动机耗油太多,浪费。怠速一般是550---750转/分钟。这个差异取决于发动机里边的惯性轮的重量。
凭记忆,我知道大约在2002年,奔驰买了这个专利就把奔驰车装上了这个brakeoverridesystem(刹车是爷系统)(太幽默了)。2003年,美国车,比如Chryslers也买了这个专利把新车安装了这个系统。接着,宝马、大众(vw)等欧洲其它车也都安装上了这个系统。如果你买的是2010年的日本车,除了Nissan外,其它的车都没有这个系统。2011年以后,美国可能不允许在美国卖车,除非安装了这个系统。
关于刹车优先系统的发展历史,以及截至2010年,这个系统在北美市场常见车包括丰田上的配置状况,鄙人找到这样一份资料:
The technology was first used in the BMW 750 in the late 1980s as a performance enhancement for heel-and-toe race-style driving , in which a driver uses the heel and toe of one foot to control two pedals at the same time. Every BMW built since 2001 has had brake override. Chrysler was the next manufacturer to use brake override in its 2003 models. These days, several car manufacturers use the technology, with more soon to follow.
简单归纳,这个技术的先驱是宝马,80年代末已开始使用。至2001年,所有宝马车型均已配备这项技术。克莱斯勒(如前面提到,鄙人老师所说,克莱斯勒总是豪不犹豫地使用新技术,却永远造不出好车)于2003年开始使用该项技术。
As of early 2010, quite a few new cars come equipped with brake override systems, but the systems aren't universal. President Barack Obama's administration recommended, but did not require, that manufacturers include the system in new cars as a response to a massive recall of Toyota models with acceleration issues.
Manufacturers with brake override in at include pioneer BMW as well as Chrysler, which has the systems in 97 percent of its vehicles (only the PT Cruiser doesn't have it). Audi, Mercedes-Benz and Volkswagen also have at least some models that use the technology. By the end of March 2010, all new Hyundais will have brake override, and by the end of 2010, all vehicles from Toyota, Lexus and Scion will use it, too.
到2010年,宝马之外,克莱斯勒配备该项技术的车型达97%(仅PT Cruiser除外)。奥迪,奔驰,大众,也有至少部分车型配备该技术。至2010年底,所有现代新车都将配备该技术,丰田所有车型,包括丰田,凌志和Scion,也将全部配备该技术。
作为对丰田踏板门事件的响应,总统奥巴马办公室建议所有汽车制造商采用该技术,但并未提出硬性要求。
对照一下,看这位阎某人都是怎么满嘴放炮的。
发动机怠速取决于进气量多少,是由电脑控制的。惯性轮决定怠速,只有丫在国内修过的“内燃机”才是这样的吧。 |
