Motorcycles are probably not the first
thing that leaps to mind upon the
mention of mission-critical applications
for wireless technology. But in World
Championship Grand Prix racing (Moto
GP), the prototype machines hurtling
around the track are largely dependent
on an Engine Control Unit (ECU). This
little black box communicates wirelessly
with software that optimizes engine
braking, traction control, shifting, and
a stunning number of other precise
functions in accordance with every
section of the track.
The necessity of the ECU was made
apparent several weeks ago at the
Estoril track in Portugal, where Ducati
rider Nicky Hayden was essentially
riding a horse without reins for the
duration of the race. Evidently a stray
radio signal interfered with the ECU’s
transponder, throwing its electronic
calibrations out of phase around the
circuit. Basically, as Hayden said after
the race, “the bike didn’t know where it
was on the track.”
This brings to mind all kinds
of questions about frequency
coordination and RF shielding. Actually,
it’s surprising this type of mishap does
not happen more often, given the fact
that racetracks tend to have just a
few wireless frequencies in operation
during events.
The essential nature of the ECU is
a particularly salient point this year in
the Moto GP, as another class of racers
known as Claiming Rule Teams (CRT, an
old acronym we know well) has entered
the fray. During these tough economic
times, it’s hard to find enough factorybacked
teams willing to pony up the
cash to keep racing in Moto GP. So now
the field has been opened to a hybrid
breed of bikes that most significantly
will lack the ECU component.
CRT racers pose quite a hazard to
faster, more precise bikes that have
factory backing. When the leaders
of the pack need to pass a cluster of
slower riders, you’re asking for trouble.
In a demanding environment where
bikes are traveling upwards of 200
miles per hour, it’s critical that a team
has invested in an ECU. And following
that, the ECU must communicate with
the real-time race data crunched by
software back in the pit. That ECU
represents the expertise, training, and
scientific marvel that can make or break
a racing team.
Maybe you’ve noted that some
of your competitors seem to lack an
ECU. But more importantly, have you
discovered what drives your ECU? And
have you communicated that data and
those advisories to your team?
As we head into InfoComm this month,
every company has a plan to make the
most of the show. Just make sure you’ve
calibrated your ECU properly. Education
and training, networking, and product
discovery are all important components
that can either give you the inside line or
send you hurtling wide at the corners.
