TECHNOLOGY REPORT
Software-based data analysis is the key to Sumitomo's Sensing Core
technology that can detect road conditions, tire air pressure and even
potential wheel detachment.
While both these problems would show up as slippage, a
Sensing Core system samples conditions every 20 milliseconds
and can therefore determine between poor road conditions
- which show up as transient events - and tire wear,
which appears as a more gradual decrease over time.
Another use case: wheel detachment warning
A Sensing Core system can detect other potential problems,
Yamamoto said, including torsional force that could cause
YURA in EV Era
We are moving the frontier of electric vehicle Technology.
With our leading-edge technology in electrical, electronic
distribution system of automobiles, we are now leading
the development of core parts for electric vehicles.
We work for new possibilities
and prepare a better tomorrow for our partners.
wheel detachment, the load on the tire and the degree of tire
friction occurring on a circuit.
" Detachment is not something that we deal with here in North
America, but in left-hand drive countries, because of the crown
of the road, when they're actually breaking braking, they're going
in an opposite force from the direction that the lug nuts are
torqued, " Johansen said. " It's a serious issue in some left-hand
drive countries, where the wheel lug nuts get loose, and the
whole wheel comes off. So, that's one of the features that has
been a key focus for us in China and in Asia, primarily. "
Sumitomo is focused on different regions for different applications,
Johansen said.
" There's a strong synergy between Sensing Core and electric
vehicles and, in the future, towards autonomous vehicles, "
he said. " The U.S. is really the third-largest market for that, so
right now, we've been working with China. We've [also] got
relationships with car makers in Japan. The U.S. has the largest
size of fleet management, and this software can also be
used from a maintenance standpoint for the operator of the
fleet to be able to track pressures, track wear, take a look at
any other conditions that may signal that a vehicle needs to
go down for service, something to take care of before it actually
becomes a roadside event. "
