A federal mandate to require backup cameras in all vehicles, expected Feb.
29, will be a bonanza for suppliers of collision-avoidance equipment.
But the mandate also could provide an unintended boost to the infotainment
industry.
If automakers install display screens for backup cameras in entry-level
vehicles, they could add no-frills applications for navigation, audio and
hands-free phone calls.
Auto shoppers are snapping up connected-car features, and General Motors in
January demonstrated the feasibility of a no-frills infotainment system when
it announced plans to equip the 2013 Chevrolet Sonic RS with MyLink.
The National Highway Traffic Safety Administration has been working on its
backup safety rules since 2007, when Congress ordered it to establish
standards. Backup accidents cause an average of 292 fatalities and 3,000
serious injuries per year, according to federal statistics.
This month NHTSA is expected to instruct automakers to equip vehicles with
video cameras that detect pedestrians behind the vehicles.
In a rule-making notice published in 2010, NHTSA tentatively concluded that
"rearview video systems are the most effective technology available today."
The agency's notice also hinted at some guidelines. A rear-facing camera
should be able to scan an area 10 feet wide by 20 feet deep behind the
vehicle, and the driver should be able to view it on a video screen.
The Insurance Institute for Highway Safety has endorsed this approach. "For
the near term, it seems like videos are the best solution," said David Zuby,
the organization's chief research officer. "Cameras appear to be eminently
feasible."
More expensive
Assuming annual light-vehicle sales of 16.6 million units, NHTSA estimates
it would cost $1.9 billion to $2.7 billion to equip new vehicles with rear-
facing cameras.
That's a revenue opportunity for collision-avoidance technology suppliers
such as Robert Bosch GmbH, Autoliv Inc., Continental AG, TRW Automotive,
Denso Corp. and others.
While video cameras are expected to cut the death toll, they are more
expensive than other detection systems, NHTSA acknowledged.
Video systems installed in vehicles without existing display screens
currently cost consumers $159 to $203 per vehicle.
In a vehicle that already has a visual display--say, for route navigation--a
video camera system would cost consumers $58 to $88, according to NHTSA.
While these are estimates, they appear to be good ballpark estimates.
For example, Gentex Inc. markets an autodimming rearview mirror with a video
display for less than $100 to automakers, said Craig Piersma, the company's
director of product marketing. The company has been shipping its backup
assist unit since 2007.
While the cost seems feasible, NHTSA must resolve some major issues. A key
question is whether regulators could adopt a fail-safe approach to collision
avoidance.
Before backing up, motorists typically check video displays, then rearview
mirrors. But studies have shown that motorists can overlook a child or
pedestrian who wanders behind the car after they glance away from the video
screen.
Piersma argues that a Gentex-style rear mirror is the best location for a
video display because motorists instinctively check the mirror when they
back up. Thus, they are less likely to overlook an obstacle detected by the
video camera.
Extra safeguards
In the long run, Piersma and others endorse a belt-and-suspenders approach
that would sound an audible alarm if the camera detects an obstacle.
Originally, NHTSA recommended that automakers start phasing in backup
monitors in the 2013 model year. Because the proposed regulations are a year
behind schedule, that deadline seems likely to be delayed.
Meanwhile, with backup cameras and nav screens on low-end cars, the
infotainment industry would get a boost. For example, Chevrolet Sonic owners
will be able to make hands-free phone calls, listen to MP3 music and get
route guidance by linking their phones to the vehicle's MyLink infotainment
system.
GM hasn't announced pricing yet. But if subcompact cars are required to have
display screens for backup cameras--along with the rest of the vehicle
fleet--it's only a matter of time before infotainment becomes a universal
feature. | l*****g

我的车就有这个，但是不是所有情况都十分准确，所以还是自己扭头看心里有底。

而且我总觉得，平时依靠惯了各种高科技的，倒车影像，雷达之类，碰到个啥都没有的
车就抓瞎了。

哪里有卖那种倒车时候大叫“请注意，倒车，。。。”的东西？
我倒车时候都要按喇叭，有时候觉得很不好意思 | R***a

但是平趴有摄像头方便的多。

其实很好解决 把外侧反光镜换成有曲面的就行了 不知道为啥美国的反光镜不仅不曲还
放大 想没有盲区都不行
