Toyota recalling more than half of Priuses ever sold to fix software glitch

Toyota Motor Corp., the world’s largest automaker, will recall more than
half of the Prius vehicles ever sold to fix a software glitch that could
slow down or bring the car to a halt.
The recall involves about 1.9 million vehicles produced globally since March
2009, spokesman Brian Lyons said. As of last year, worldwide deliveries of
the Prius line of vehicles exceeded 3.6 million units since its release in
1997, according to the Toyota City, Japan-based company.
While the top seller of hybrid cars is headed for record profit this fiscal
year, driven by the weaker yen, Toyota continues to face recalls that have
damaged its reputation as a quality leader. The company called back more
vehicles than any automaker in the U.S. in each of the last two years,
according to the National Highway Traffic Safety Administration.
“My impression is Toyota is recalling more often, even with very minor
flaws” with its vehicles, said Yuuki Sakurai, the Tokyo-based president of
Fukoku Capital Management Inc. “Toyota learned its lesson from the big
recalls in 2009 and 2010.”
A flaw with the software in the Prius’s hybrid system may cause some parts
to overheat in certain driving situations such as accelerating from a stop,
Lyons said. This can lead to the car entering a failsafe mode, where it can
still be driven while at reduced power. In limited cases, the hybrid system
could shut down and cause the vehicle to stop.
Toyota hasn’t received any reports of accidents or injuries related to the
software problem, Lyons said.
Toyoda’s Efforts
President Akio Toyoda has spent years trying to restore his company’s
quality standing after recalling more than 10 million vehicles for problems
related to unintended acceleration in 2009 and 2010. The 56-year-old
grandson of Toyota’s founder hasn’t announced any new car plants since
January 2012 to avoid a repeat of over-expansion that he said was to blame
for those recalls.
Toyota has been the auto industry’s hybrid leader, having built three
generations of the main Prius model and adding derivatives such as the Alpha
wagon, also known as the v, since 2011. The recall announced today involves
only the third generation of the main Prius model, Lyons said.
Aside from the Prius, Toyota said it will recall about 260,000 other
vehicles in the U.S. That campaign involves a separate issue with the 2012
and 2013 model years of the Toyota Tacoma pickup, the Lexus RX 350 sport
utility vehicle and the 2012 Toyota RAV4 SUV.
Software Issues
A software issue with those models can cause their stability, anti-lock
braking and traction controls to intermittently turn off, though the
standard braking operation in those vehicles would remain fully functional,
according to a statement on the company’s U.S. website.
The recall follows Toyota forecasting that profit for the year ending March
31 will surge to a record 1.9 trillion yen ($18.5 billion).
The company has set a target of selling an unprecedented 10.32 million
vehicles in 2014 after leading General Motors Co. and Volkswagen AG in
global deliveries for a second straight year in 2013.
Worldwide deliveries for Toyota, including those of subsidiaries Hino Motors
Ltd. and Daihatsu Motor Co., rose 2.4 percent to 9.98 million units last
year. Volkswagen and its MAN SE and Scania AB heavy-truck units followed
with 9.73 million sales, the Wolfsburg, Germany-based carmaker said last
month. GM was third in the industry with 9.71 million.
Toyota isn’t alone in emphasizing quality. U.S. automakers including
Detroit-based GM are cracking Japanese brands’ dominance in fielding cars
with leading quality and reliability, Consumer Reports said last year. While
models from Toyota and Honda Motor Co. held the top three spots in the
magazine’s annual auto-reliability survey released in October, GM’s GMC
and Buick posted gains and Volkswagen’s Audi luxury brand made the top five.

咖喱程序员搞出来的更多是功能上烂,bug多
但还没有丰田那么烂
1,67条函数复杂度超过50,而在这67条函数中还有12条复杂度超过100,达到“非可维护
”级别,意味着一旦发现缺陷(Bug)也无法修复,因为实在太复杂,修复缺陷的过程
中会产生新的缺陷。其中最复杂的一条函数有超过1300行代码,146个可能执行路径—
—正好用于根据各传感器数值计算节气门开关角度。
2,包含了超过一万一千个全局变量
3,丰田辩称他们遵循的不是行业规范,而是丰田内部编程规范。这一规范与行业规范的
吻合程度达到50%。但是Barr认为根据他的调查,两个规范之间吻合度小于10%,甚至有
若干规范条目相互冲突。后来发现丰田的代码甚至没有遵循丰田内部规范,当然比起别
的问题这个已经无关紧要了。
4,MISRA C拥有超过100条规范,NASA的调查只使用了到其中35条进行校对,发现丰田
程序里超过7000处违规代码,Barr使用全部条目,对照结果是丰田的程序拥有超过
80000处违规代码。
5,在2008年款凯美瑞中使用了3比特长的EDAC。Barr认为是为了节省成本,否则应该使
用5比特长。
6,还有值得一提的是,汽车相关的软件行业有那么几家操作系统供应商,早已形成了
一套成熟标准称为OSEK。各供应商开发的符合OSEK认证的操作系统至少都能达到一定的
质量
。但丰田选用的操作系统却没有通过认证
7,NASA在他们的调查中重点排查堆栈溢出的可能性。于是NASA问丰田,丰田的回复是
最坏的情况下4KB堆栈只写入了41%的数据,换句话说发生溢出的可能性非常低。NASA直
接取信了这个数字并没有再深入调查。但Barr他们发现丰田的回答有严重低估,实际上
最坏的情况会达到94%,而且还不算递归。丰田在代码中使用了递归
………………

不是没收到,而是收到了不往这上面靠
例如软件缺陷导致自动加速怪到脚垫上,然后又怪到踏板上
反正总之就是不承认是软件缺陷引起的
这一次我想一样是如此,就是为了说明没人投诉,凸显所谓的reliable,弄不好背后投
诉都一大箩筐了
国内自动加速撞车死人的,丰田都说是车主自己操作失误,一分钱不赔

Not just Prius!
http://www.cbc.ca/news/world/toyota-canada-recalls-39-000-vehic
The voluntary recall in Canada also includes a total of 25,577 of the
following vehicles sold in the country (Toyota Canada didn't provide a
breakdown of the number of each make):
■2012 Toyota Rav 4.
■2012-2013 Toyota Tacoma.
■2012-2013 Lexus RX350.
Toyota said a software problem in these vehicles can cause the vehicle
stability control, anti-lock brake and traction control functions to
intermittently turn off.
