发帖数: 2001 | 1 这些措施, 回头整个想一下逻辑,
问题本身是因为 油门信号 处理不正确,出错
汽车自动就突然来个地板油
为了解决这个问题,加个 刹车override,
好,需要刹车信号.
且慢,又不能所有时候都需要 刹车override,
好吧,再加一个离合器信号.
单搞定一个 油门信号,目前偷油塔这系统都靠不住,
又咋能就确信它的刹车信号和离合信号,车速信号,转速信号都是正确的呢?
东西越加越多,算法越搞越复杂,到时候真不见得就有多可靠
当然所有环节都出错的概率是非常非常低的,
但是这种病急乱投医,加一堆东西上去,
说不定又会搞出些新的failure mode.
到时候,不该override的时候override了,改override时候....
我觉得解决问题还是得找出root cause,
先弄明白油门问题本身是咋回事.
问题不去正面解决，它不会自己消失，
加了brake override，
车突然冲了，踩一下brake，油门强制减到idle，不会出事故了，
（也难说，在高速上突然就这么慢下来，然后停住。。。）
这仍旧不是一辆正常运行的车，
三天两头要来这么踩踩闸，重启一下，谁受得了啊。

标 题: 97:1，Senators vote to override Obama's veto of 9/11 bill
发信站: BBS 未名空间站 (Wed Sep 28 12:39:39 2016, 美东)
Senators voted 97-1 Wednesday to override Obama's decision to scuttle the
bill. The override vote came even as the president and top military
officials warned the measure could put U.S. troops and interests at risk.

发帖数: 9567 | 6 在2002 年，有人研究出了“ brake override system”(中文有人翻译成“刹车优先系

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。
大约在2002年，奔驰买了这个专利就把奔驰车装上了这个brake override system( 刹
车是爷系统 ) 。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。

发帖数: 9567 | 15 如果您在2000 年以前开过车，您应该知道，那时候的车油门踏板是直接连到油门开关
上的，也就是说，你踩的是油门本身。后来，电脑的发展用在了汽车上。油门踏板不再
跟油门开关相连，而是跟电脑相连。你踩的不是油门，是电脑。电脑根据信号，再给油
门开关下命令。所以，问题就大了。首先，油门踏板是否会出问题，是否会卡住。然后
，即使没有卡住，那个sensor 是否坏了。一旦坏了，你踩油门了，车不走。但不会加
速。这个道理很简单：每个车的电脑都有 default setting ，什么意思呢？就是不论
电脑出了什么问题，比如电脑得不到信号，那就死火。断不会有电脑坏了而加速的设置
。但要是油门开关本身卡住了，就像油门踏板卡住一样，那就不能减速了。

发帖数: 4192 | 16 我开奔驰，2009年的C300 Luxury.
车子不动的时候（发动机已热）发现放在P,N挡，发动机转速比放在D挡加刹车要慢，大
概D档1100，P/N 900。我理解P/N档就是idle的速度，为什么刹车踩到底，转速不下去
？发动机转速在运行过程中，好像只和车速有关系。轻踩刹车（一般用来提醒后面的人
不要跟太近，刹车灯亮，我不知道是否trigger这个brake override),发动机转速不变
，车子也没有减很多速度的迹象。下坡踩刹车，只要车速加快，发动机转速一样快。
我就想知道我的车到底有没有brake override。如果有，开车时怎么表现出来的？ |

be accessed in Children's method body via super.
But can they be accessed outside Children's method body?

B b=new B();
now how to access b's overrided String t?

发帖数: 137 | 21 Sure, if you don't override the toString() method in the derived class, you
will inherit one from the base class but that method only has access to fields
defined in the base class.
If you override it, then you can use a base type to refer to the derived type
and the right method will get called:
Derived d=new Derived();
System.out.println(d); //derived
Base b = new Derived();
System.out.println(b);//derived.
These two calls are the same.

Just a minor note - technically a final method is still a virtual method, only
it cannot be overriden (note "virtual" is a different concept than
"overridable"). It could still have an entry in the table, if it overrides a
method from the base class. |

发帖数: 137 | 49 1) Define a variable with the same name in a derived class will "hide" the
variable of the same name in the base class, but it's not called "overidding".
You only override a method, not a variable.
2) Both C++ and Java use static typing, which means the variables are resolved
at compile time. So if if you directly cast your derived class into a base
class, and try to refer to the variable, then the one defined in the base
class will be used. Ex:
class base{
public String value = "Base";
}
