Scheduling OTA updates
Generally speaking, the process
for enacting OTA updates is fairly
straightforward, Mallela said. With
Navistar, any fleet manager with
programming rights can initiate the
remote updates. New engine calibrations
are periodically added to
the OnCommand Connection dashboard
for all customers. Those software
updates also can be initiated
by fleets when they so choose. Once
approved by the fleet manager, the
driver then receives an in-cab alert
via the dash and can select when to
initiate the update.
" When a new engine software/calibration
is released, the fleet manager
can approve the update to a select
truck, a subset of trucks, or all trucks
in the fleet, " Mallela added.
Once approved, the software
is downloaded over the cellular
network onto the vehicle. When this
is complete, the driver is notified
through a dash alert that a software
update is available. The driver can
then perform the update at his or her
convenience by approving the update
on the dash.
" The fleet manager has complete
visibility of the process: vehicles
awaiting download, downloads in
progress, calibrations in progress,
calibrations refused/deferred, and
vehicles that are up to date, " Mallela
added. " In fact, customers can initiate
parameter changes, things like
adjusting throttle pedal and cruise
control speeds, specific to some or
all of their fleet vehicles, whenever
they choose. "
planned maintenance event, " he
said. " If it's a warrantable update that
could prevent something serious like
the engine derating, it could be in the
fleet's best interest to update during
the driver's next stop. "
For Navistar, giving fleet managers
complete control over the OTA
process
is critical, according to
Mallela. " We designed our system to
provide the fleet manager and drivers
complete control of the process
to perform the updates based on
their convenience and schedule, " he
said. " The fleet manager can authorize
the update to select vehicles or
an entire fleet. Once the update is
downloaded onto the vehicle, the
driver can approve the calibration
and start the update process at his
or her convenience. "
Volvo recently introduced Driver
Display Activation, which moves
the activation step into the cab and
the hands of the operator, adding
flexibility and another option over
having to call a Volvo Action Service
agent to initiate a remote update,
Murickan noted.
" Having the latest updates and
change settings is easily and quickly
accessible, " she added. " Updates
which previously required trucks
to be taken out of operation to have
them hooked up to a laptop at the
dealership are now updated in a few
minutes remotely when the truck is
parked for dispatching, or the driver
is taking a break. These features have
also gained the drivers' appreciation,
as they maximize productive driving
time, allowing [drivers] to earn more
money. And what we see today is
" Whether it's an engine, ADAS,
transmission, or other major
component, the OE provides
the applications that can push
these updates over the air. "
Lee Lackey, product manager, Noregon
On the other hand, given the
current state of OTA technology, fleet
managers do need to consider OTA
updates on a case-by-case basis to
determine when to schedule them,
Lackey cautioned. " If it's a minor
update that won't affect the truck's
safety or performance, fleets can
wait until scheduled downtime or
even have it done during the next
only the beginning; customers can
expect more features to be introduced,
and parameter updates will
become more dynamic and enable
the truck to adapt automatically to
local conditions. "
If the light-duty side of the industry
is any indication, minor OTA updates
may soon become a relatively routine
occurrence for fleets.
