发帖数: 777 | 2 Yea, I think that's why my friend said I should push the brake at first and
then push the cluch or change to nuetral.
When the car is in nuetral gear, the gas pedal can't control the car. I
think that's why we should change to neutral gear when the car is out of
control. |

发帖数: 2233 | 6 "engine brake"是换到1/2档的时候engine会自己制动，和刹车无关
如果车自己加速停不下来，先换空档，再踩刹车是正道
有些车（比如video里的Jetta等德国车）踩刹车会自动切断油门(brake override)，所
以也可以省掉换空档这一步
没有brake override的车，譬如toyota这种情况，就得换空档列
另外不能pump brake，一定要死死踩住不松，松一下之后真空没了也会刹不住的 |

发帖数: 7583 | 9 其实我一直想说，要车真的在路上失控了，除了换空挡踩刹车之外，还要同时亮紧急灯
，免得后面的车没留意你减速了撞上。 |

发帖数: 2218 | 10 1) engine brake不是１／２档的时候才有，本质上是engine的某种机制使它变成＂耗
能＂而不是＂供能＂的部分， 加上传动部分不分离，会使车子减速。大下坡的时候３
档，４档都可以用来控制速度（减），只是在用低档的时候（１／２档）, 刹车效果更
明显。
2) ＂如果车自己加速停不下来，先换空档，再踩刹车是正道"
这个肯定很少见，基本上自动车都要踩刹车才能进空档的吧，反正我的车是这样的；手
动车，换档肯定要踩clutch，但是换进空档，是不是一定要踩clutch，我都不记得了，
以前那辆手动车还是７年前的事了；现在有的那些semi－automatic，我还真没开几次
。all in all， 如果车子进空档，没有什么secondary的控制，我觉得是个很危险的设
计。
注意听那个video １＇４２＂处，he said, " put your foot on brake HARD, put
car on neutra......"
3) 这个video里没有说明＂pump the brake＂是什么意思，可能给人理解后面的＂put
foot on brake HARD" 造成 |

发帖数: 2218 | 11 not necessarily, I tried that on both manual car and automatic car before.
The parking brake of manual car worked well just like a pedal brake, but the
parking brake of automatic car was weak since it was not the intended
function anyway. |

发帖数: 2233 | 12 偶说的是自动车
手动车，可以一级级换下去。。。
大多数自动车可以直接换空档
有些车开的时候换成倒档都可以，不怕伤车的话可以去试试，呵呵 |

发帖数: 2218 | 17 The pedal brake gets "assisting" power, while the parking brake does not.
The parking brake is not meant for braking when moving, I am not sure it
would damage the car if one ever use it. |

发帖数: 777 | 18 手动档换进空档也是要踩clutch的~
我不懂车,但总觉得空档挺危险的~
今天中午同事给我的练习是半坡起步,但不能利用手刹控制,汗啊~我就在那儿滑~
每天午饭时间都是惊魂时刻~哎~ |

发帖数: 2218 | 19 ok, it jogs some of my memory. I don't think cars of automatic transmission
would allow entering neutral without pedaling the brake (or by some other
mechanics), it is just too dangerous because the shift stick can be knocked
into neutral accidentally and the car is out of control.
But, I just didn't have much time spent with those semi-automatics. |

发帖数: 188 | 20 thanks for explanation. I heard using parking brake when moving is not good
for the car, at least the brake may be worn out faster. In some rare cases
when I forgot to release the parking brake before driving and recognized
later, even if the speed waslow and the time was short, I felt very sorry
for the car ... |

发帖数: 188 | 21 Are you sure? I think manual car can change into neutral without stepping
on the clutch, although it is necessary to push the clutch when changing to
any other gear. |

发帖数: 777 | 22 My friend told me if you keep going and forget to release the parking brake
for a long time, the car will inflame. I don't know if it's true.

发帖数: 2218 | 24 You are right about not releasing the parking brake, it is like tapping
pedal brake all the time while driving. Anyhow, I think most of us did it
once or two at least in our "driving career". For a manual car, if the
parking brake is on, you will very likely to notice it.

挂”住，不死车，就行了，呵呵。。。 |
