标题:1104622辆!因安全问题,特斯拉在华启动最大规模召回
根据《缺陷汽车产品召回管理条例》和《缺陷汽车产品召回管理条例实施办法》的要求。日前,特斯拉汽车(北京)有限公司、特斯拉(上海)有限公司,向国家市场监督管理总局备案了召回计划。具体如下:
特斯拉汽车(北京)有限公司、特斯拉(上海)有限公司自2023年5月29日起,召回生产日期在2019年1月12日至2023年4月24日期间的部分进口Model S、 Model X 、Model 3及国产Model 3 、Model Y汽车,共计1104622辆。
本次召回范围内的车辆,没有允许驾驶员选择能量回收制动策略;同时,对驾驶员长时间深度踩下加速踏板的情况可能没有提供足够提醒。以上因素叠加可能增加长时间误踩加速踏板的概率,可能增加碰撞的风险,存在安全隐患。
据悉,本次召回活动是在国家市场监督管理总局启动缺陷调查情况下开展的。受调查影响,特斯拉汽车(北京)有限公司、特斯拉(上海)有限公司计划通过汽车远程升级(OTA)技术,为召回范围内的车辆推送新开发的功能,以降低因长时间深踩加速踏板导致速度过快引起的碰撞风险。功能包括:(1)在不具备能量回收制动强度选择的车辆上,提供选项以允许驾驶员选择能量回收制动强度;(2)调整车辆能量回收制动策略的出厂默认状态;(3)在驾驶员长时间深度踩下加速踏板时发出提醒。
Tesla Dismisses Chinese Investigation on SUA Cases By Recalling 1,104,622 BEVs

Costas Lakafossis was the engineer who announced a feasible explanation for sudden unintended acceleration (SUA) episodes. After investigating several cases, he found out that the Autopilot software made the car behave in a way that induced pedal application errors. It seems China's State Administration for Market Regulation (SAMR) heard him and started an investigation. Tesla decided to prevent it by filing a recall for 1,104,622 BEVs.
That includes all vehicles the
American BEV maker
has sold in China since January 12, 2019. Imported units of the
Model S, Model X, Model 3, and Model Y are included,
as well
as the Model 3 and Model Y made at Giga
Shanghai.
Why doesn't the recall list all vehicles Tesla ever sold in China
since August 2013? The explanation seems to be related to
the "energy
regenerative braking strategy."
According to SAMR, all units in the recall do not allow the driver
to select the strategy they prefer the car to follow. While it
could seem that the recall relates only to that point, the Chinese
regulator also clarified that these
vehicles "may
not provide enough reminders when the driver depresses the
accelerator pedal deeply for a long time. The superposition of the
above factors may increase the probability of mistakenly stepping
on the accelerator pedal for a long time, which may increase the
risk of collision and pose a safety hazard." This
is supposedly the cause of several crashes
in China and
elsewhere in which the drivers sustain that the brakes
failed.
At Auto Shanghai 2021, Zhang Yazhou became world-famous when she
jumped on top of a Tesla Model 3 to protest against her vehicle's
defective brakes. She wore a T-shirt that
said "Brakes
Lost Control" and "Invisible
Killer" in
Chinese. Yazhou was arrested for "disturbing
public order" and
later sued by Tesla for "reputation
infringements."
On November 5, 2022,
6:42 AM local time in Chaozhou, a Tesla Model Y driver, identified
only as Zhan, was apparently trying to park his car in front of the
cement store he runs in that city when the Model Y started
accelerating. It drove for 2.6 kilometers (1.6 miles) at high
speed, hitting several vehicles and killing two people, until a
final crash made it stop for good. Tesla said the data in his car
indicated he had the right foot on the accelerator pedal all the
time. Zhan denied that, stating he kept his
foot "on
the brake pedal all along" until
he "was
on the verge of colliding with the tricycle."
On February 17, a Tesla Model 3 was out of control in Ruian. It
went from near miss to near miss until it crashed the back of a
bus. The driver was taken to the hospital in bad condition, and the
passenger reportedly died in the crash. Apart from these cases in
China, a Tesla Model 3 also experienced a similar
situation on
December 11, 2021, at around 9 PM in the 13e arrondissement in
Paris. The crash injured 21 people and killed one. The taxi driver
is suing the American BEV maker.
In all these cases, Tesla later said that the accelerator pedal was
pressed instead of the brake pedals. That led Chinese Tesla owners
to install cameras to film the pedals. The idea was to prevent the
company from accusing them of pressing the wrong ones should they
experience similar SUA incidents. The new Chinese recall may help
to avoid them.

When Lakafossis
discovered that Tesla vehicles brake and
accelerate on their own when drivers are trying to park, he linked
that to a break in the feedback loop sequence that helps us
automate actions in open-loop control. Instead of preventing
Autopilot from doing that, the engineer and accident investigator
proposed to have Tesla include Brake Transmission Shift Interlocks
(BTSIs) in its vehicles. That would demand the driver to step on
the brakes to shift from drive (D) to reverse. Currently, these
BEVs allow the driver to shift gears without stepping on the brake
pedal.
Considering this was a voluntary recall that Tesla filed to escape
the SAMR investigation,
the company may have found a different way to solve SUA incidents.
Instead of following Lakafossis' recommendation to use BTSI, it
will allow its vehicles to select how they want to recover energy
from braking and warn drivers if they press the accelerator pedal
for a long time. This alert alone may help drivers realize they are
stepping on the wrong pedal – hopefully in time to avoid a
tragedy.

Lakafossis told me that having a creep mode as standard would
probably help avoid these SUA
incidents, which always happen when the involved Tesla drivers
are trying to park. It would make these people aware that they need
to step on the brake pedal, as they would do in any conventional
automatic car. This is probably what the regenerative braking
strategy will allow Tesla owners to select. Too bad if they choose
the wrong regenerative mode, but at least the car will warn them
that they are stepping on the accelerator instead of the
brakes.
I discussed this situation with a software expert, who told me
that "there
is no data showing that unintended acceleration is predominantly
caused by sustained pressing of the
accelerator." In other words, it would be
nice if what Tesla states
caused the crashes could be confirmed by third parties. This
specialist made a very pertinent
question: "If
you suspect the computer of defectively commanding acceleration,
why would you trust what it tells you about the pedal position it
is basing that behavior on?"

In their opinion, "there
is a multi-decade history of the car companies and NHTSA blaming
drivers for pressing the wrong pedal, even though their arguments
are based on a case in which the car DID accelerate due to a design
defect, and there have been recalls for design defects that led
cars to accelerate on their own since then." Despite that, they
also think using BTSIs "can help with that, and should be enforced
for all vehicles."
Lakafossis told me
that "this
is pure speculation, probably based on the flawed theory about
negative spikes." According to the accident
investigator, "there
is absolutely nothing that points toward this theory. It has been
investigated many times, always with negative
results." For
Lakafossis, "it
all boils down to neuroscience." "I can't think of any other
possible explanation."
Let's hope that the Chinese recall solves this once and for all –
and that it is applied to BEVs worldwide as well. The recall will
be performed by over-the-air
(OTA) updates, which makes that even more straightforward. That
will work as an excuse for some people to argue it is not a recall.
Still, only those more worried about their investments than about
safety will ignore that any repair or update related to saving
lives configures a recall. This
one in China definitely fits that
bill.
