CES 2015: Toyota opens up hydrogen patents
Toyota used physicist Michio
Kaku to talk about its hydrogen-powered car
It said it took the step in a bid to drive development of cars that use the
alternative fuel source.
The announcement was made soon after it showed off its Mirai hydrogen-driven
car in Las Vegas.
Toyota is one of a record number of car makers attending CES to unveil new
models or connected-car strategies.
Power plan
The patents will be made available free of charge to anyone wanting to use
them. The patent portfolio covers fuel cell stacks, high-pressure hydrogen
tanks, software control systems and the industrial processes involved in
generating and supplying the gas.
"When good ideas are shared, great things can happen," said Bob Carter,
senior vice president of automotive operations at Toyota in a statement.
He added that the first generation of hydrogen fuel cell vehicles, which are
expected to be launched over the next five years, would require "unconventional
collaboration" among car makers, governments, power firms and researchers.
BMW showed off its "active
assist" technology that does away with the need for a driver
While the infrastructure to support electric cars is slowly starting to
appear in many nations, re-fuelling stations for hydrogen powered cars are much
harder to find. By opening up its patents, Toyota hopes to boost the number of
places that fuel-cell powered cars can fill up.
The announcement was made soon after Toyota showed off its Mirai car at the
tech show. The hydrogen-powered vehicle went on sale in Japan in December and
will go on sale in Europe and the US in late 2015.
Toyota's move follows that of Tesla motors which shared its patent portfolio
in 2014.
A total of 10 car firms are attending CES in 2015 - more than ever before.
Some, such as Audi and BMW, are showing off innovations that help drivers park,
avoid crashes or which can take over behind the wheel when cars are on motorways
or major roads.
As a publicity stunt Audi is attempting to let a specially-made A7 drive
itself 550 miles from San Francisco to the tech show. Test drivers and
journalists will be passengers in the car and will take over when the vehicle
passes through towns and cities. Audi said the "piloted driving" system in the
car is almost ready to put in its production models.
Volkswagen unveiled a gesture-controlled in-car entertainment and information
system which used a 3D camera tucked into a compartment by the rear view mirror.
This captures hand gestures activating buttons on touch screens between the
driver and passenger seats.
The Golf R Touch system enables people inside to open and close the sun roof
by with a push gesture.
Some tech firms such as Google
are considering creating their own autonomous vehicles
VW's new cars will also be connectable with smartphones via both Android Auto
and Google Car Play apps by the end of 2015 in the US and Europe, said spokesman
Peter Thul.
It is also continuing to work on autonomous driving and parking technology,
he added.
The presence of so many auto makers is seen as a response to the number of
tech firms that are steadily aiming to get their innovations into cars or, like
Google, produce their own autonomous vehicles.
At its press conference, Nvidia talked about its Tegra X1 processor, which it
claims will have the power to handle the computational needs of futuristic
autonomous cars.
Processing units it demonstrated will be analysing data from sensors or
processing images that appear on screens inside a car to help a driver or to
entertain passengers.
In addition, Qualcomm showed off a concept car powered by Android 5.0 that
handles entertainment and keeps an eye on what is happening on the road.
