When the cruise control is in effect, the throttle can still be used to
accelerate the car, but once the accelerator is released the car will then
slow down until it reaches the previously set speed.
不会自动加速，只会匀速或减速。 |

WASHINGTON - Some Toyota owners say they're still having trouble with
unintended acceleration after their recalled cars were repaired, and the
Transportation Department said Wednesday it is looking into their complaints.
The complaints raise new questions about whether Toyota's remedy will solve

Not one day after a high-profile incident involving a Prius taking off on
its owner in Southern California, we're hearing reports that another one of
Toyota's popular hybrids has suffered unintended acceleration in New York.
This time, instead of the car eventually succumbing to the will of its
braking system, it crashed into a stone wall. Fortunately the owner was
reportedly just pulling out of her driveway in Harrison, NY and the car only

sudden acceleration tends to stem from operator error. If the reports of

be nothing and no one left to blame but the driver.

发帖数: 14557 | 9 That is right.
What I was saying is that, by knowing when to push or release the gas pedal,
one can put a car at the right gear. For example, when cruising at the
speed of around 40mph, a car could be at the 4th gear or at the 5th gear (
assuming the car's top gear is 5th). If I don't expect any need to
accelerate, I would put my car at the 5th gear. The trick is to accelerate
to a speed higher than the set speed and then let go the gas pedal a bit. |

是的话就是我说的那两个可能
"The key is acceleration. If a vibration exists when coasting or at a
sustained speed, it's balance, bent wheel, tire, etc, but if under
acceleration, inner CV joints worn providing the motor mounts aren't
completely shot changing the driveline angle." |

发帖数: 2045 | 48 Recall is for floor-mat trapping pedals, which according to NHTSA official
report was the only problem in Toyota vehicles. Government found no problem
with brake or electronic throttle.
The report (Feb 2011) found that ALL Unintended Acceleration can be stopped
simply by stepping on the brake. One conclusion is the most likely cause of
some acceleration complaints is "pedal misapplication" (I call it just
stupidity).
This is Audi in the 80's all over again.

发帖数: 1807 | 49 请版上的大牛帮忙把把关，上周一辆车hit and run了我的车，我当时抄了车牌，报警
，警察根据我的描述判了对方的责任，今天警察局告诉我，对方司机已经找到，证实了
他的车和我的车有刮蹭，警察给了他俩ticket，同时把对方保险信息告诉我，让我通知
保险公司，现在唯一要注意的是，对方的保险公司和我一样是geico，听说geico有时候
很极品，会尽力从索赔者描述找找flaw，然后把责任改成50-50，万能的车版是我索赔
的依靠，我把我的事故描述发给大家看看，麻烦大家帮我找找碴，前10个包子答谢。顺
利拿到赔偿，另外有双簧包答谢。
先是我的中文描述：
晚上8点左右，我开车从东面的入口进入一个十字路口，当时我怀孕的妻子在车上，我
要左转，这个路口有两条左转lane，我在右边的左转lane，并在整个事件中一直保持在
同一条lane上，我将转到南边的通路，南边通路有两条lane，所以我左转完之后，我仍
然在右边的lane，当我进入路口的时候，左转绿灯一直在亮，在我已经完成左转，进入
南面的路口并开始知直行的时候，一辆从西边入口进入十字路口的车开始右转，打算转

大家仔细看文章,里面说得很清楚:Could electronic systems or electromagnetic
interference cause unintended acceleration in Toyota vehicles?
实际上这个study只是说明了,电子系统故障或电磁干扰不会造成自动加速,并没有否定
踏板卡住会造成自动加速的事实.实际上这种机械问题造成的自动加速,是不可能被否定
的,因为就是铁证如山的事实.
继续看:Now, this doesn't mean that we haven't asked Toyota to accept
responsibility for known mechanical causes of unintended acceleration. We
have. |
