资深又见大※※。拉黑。

看来你爸妈没有教过你什么叫做礼貌

牛B都是自己造的，自己造不出，就别酸葡萄了。

欣然采纳丰田前来舔沟的变速箱，就是因为爱信价钱比 ZF 8HP90 便宜 20% ， 服务态度还更好，开放研发成果给前来临幸的嫖客

最为奖励，途锐车上的导航影音系统 RNS850 （哈曼.贝克的系统） 也打赏给爱信的比利时工厂代工

还是那句话，牛B ，就别出来卖！ 本帖最后由 原版咕咚 于 2013-10-27 20:02 编辑

这个代码也可能是白人写的吧。

"We found many big mistakes in the Toyota analysis that NASA relied on."

丰田给源码啦？

途锐用的变速箱 AL-1000 是丰田旗下爱信精机跪进给大众集团的，丰田自己连 Lexus LS-460 和皇冠 Majesta 用的 8AT 都是这个箱子减功能降扭矩的太监版，纯粹是给大众舔沟的

要召回就赶紧召回啊，爱信卖一个罚俩,

小弟，先想办法让大众把咱们途锐变速箱那个什么环扣给召回了吧，这个是要自己的命的呀！

哪那么多功夫操别人家的心？

意思就是一些美国的嵌入式专家检查和测试了丰田的控制系统源代码（似乎是2005年 凯美瑞L4-第四代？）之后，发现存在内存管理错误，会导致某些关键性的变量对位失序。——这应该是此前沸沸扬扬的丰田车意外加速问题的原因。

丰田的软件有问题，一个有经验的软件工程师，开过，感觉都能感觉出来，例如，某些型号凯美瑞空调的车内循环开关逻辑混乱，经常导致不可预料的开关行为。

黄种人，在逻辑理性严谨方面，似乎先天不如白种人。

所以，车的电子控制功能，还是适量为好。 本帖最后由 巨大防抖 于 2013-10-27 19:26 编辑

但是只能证明车有可能自动加速，那刹车也就碰巧失灵了？（本句为本人观点，非引文翻译） 本帖最后由 一九七八 于 2013-10-27 19:11 编辑

意思就是皇军粗大事了

戏剧性的一幕啊！

什么脚垫，什么nasa权威鉴定皇军无缺陷，什么米国陷害阴毛论。。。这下皇军不会真的现国际大眼，把忠心耿耿的慰安妇后代伪军一起卖了吧？

Toyota Case: Single Bit Flip That Killed

MADISON, Wis. — Could bad code kill a person? It could, and it apparently did.

The Bookout v Toyota Motor Corp. case, which blamed sudden acceleration in a Toyota Camry for a wrongful death, touches the issue directly.

This case -- one of several hundred contending that Toyota's vehicles inadvertently accelerated -- was the first in which a jury heard the plaintiffs' attorneys supporting their argument with extensive testimony from embedded systems experts. That testimony focused on Toyota's electronic throttle control system -- specifically, its source code.

The plaintiffs' attorneys closed their argument by saying that the electronics throttle control system caused the sudden acceleration of a 2005 Camry in a September 2007 accident that killed one woman and seriously injured another on an Oklahoma highway off-ramp. It wasn't loose floor mats, a sticky pedal, or driver error.

An Oklahoma judge announced that a settlement to avoid punitive damages had been reached Thursday evening. This was announced shortly after an Oklahoma County jury found Toyota liable for the crash and awarded $1.5 million of compensation to Jean Bookout, the driver, who was injured in the crash, and $1.5 million to the family of Barbara Schwarz, who died.

During the trial, embedded systems experts who reviewed Toyota's electronic throttle source code testified that they found Toyota's source code defective, and that it contains bugs -- including bugs that can cause unintended acceleration.

"We've demonstrated how as little as a single bit flip can cause the driver to lose control of the engine speed in real cars due to software malfunction that is not reliably detected by any fail-safe," Michael Barr, CTO and co-founder of Barr Group, told us in an exclusive interview. Barr served as an expert witness in this case.

A core group of seven experts, including four from Barr Group, analyzed the Toyota case. Their analysis ultimately resulted in Barr's 800-plus-page report.

In Toyota's own view, though, the automaker had been already exonerated when the National Highway Traffic Safety Administration closed its probe of Toyota models in February 2011. The NHTSA decision came after NASA investigated Toyota's electronic throttle control system and found no electronic causes of unintended acceleration during a 10-month review.

But not everyone in the embedded systems industry thinks NASA had enough time to come up with a complete report. Perhaps more significantly, in its report, NASA itself did not rule out the possibility of software having caused unintended acceleration.

The group of seven experts was given the task of picking up where the NASA investigation left off.

"We did a few things that NASA apparently did not have time to do," Barr said. For one thing, by looking within the real-time operating system, the experts identified "unprotected critical variables." They obtained and reviewed the source code for the "sub-CPU," and they "uncovered gaps and defects in the throttle fail safes."

Further, the team ran simulations in the Green Hills Simulator. "This confirmed tasks can die without the watchdog resetting the processor." His group also independently checked worst-case stack depth. "We found many big mistakes in the Toyota analysis that NASA relied on."

The experts demonstrated that "the defects we found were linked to unintended acceleration through vehicle testing," Barr said. "We also obtained and reviewed the source code for the black box and found that it can record false information about the driver's actions in the final seconds before a crash."

It's important to note Barr Group testimony led to a billion-dollar economic-loss settlement by Toyota last December. Because of that settlement, details of the technical discoveries made back then by the experts were not made public until the Oklahoma trial. The economic-loss settlement resolved hundreds of lawsuits claiming vehicles depreciated after the company issued recalls related to faulty acceleration. Toyota still faces lawsuits claiming injury or death related to the recalls.

Task X death
Now that the experts' testimony and findings have been made public through the Oklahoma trial, let's get into details. What defects were found in Toyota's electronic throttle control systems?

Barr said that the 2005 Camry L4 source code and in-vehicle tests by the experts confirmed that some critical variables are not protected from corruption, and sources of memory corruption are present. He believes that Toyota's engineers sought to protect numerous variables against software- and hardware-cause corruptions, but they failed to mirror several key critical variables, and they made no hardware protection available against bit flips.

Stack overflow and software bugs led to memory corruption, he said. And it turns out that the crux of the issue was these memory corruptions, which acted "like ricocheting bullets."
