ied their equipment failures and found that more
than three quarters of failures were categorized
as random.
A random failure is one that is not proceeded by notable deterioration. It could be due to
a component with a hidden defect that finally
surfaces, or a mis-operation of the equipment.
Fleets can help lower random failure modes
through processes such as driver training on
defensive, or comprehensive, pre- and post-trip
checklists. But once in operation, fleets currently
cannot anticipate these failures.

Telematics functionality
of today
Paccar's full-service leasing group, PacLease,
provides Kenworth and Peterbilt trucks to fleets
across the U.S. Each of the company's 3,500 units
communicates critical conditions to dispatch in
real time. The fleet maintenance manager can
either communicate with the customer's dispatcher or, in some cases, the

be monitoring 50 to 100
sensors in various parts of the power unit alone
(not to mention additional sensors monitoring
trailer information).
Since tires are one of the biggest operating
costs, they are closely monitored. Take an overinflated tire for example (See Fig. 1). Overpressure
can only come from incorrect filling of the tire
with air. Simply reducing some pressure will
directly increase tire life and save money. The
intervention stops a failure cascade in its tracks.
A side benefit is that this level of knowledge
dissuades drivers from many types of behaviors that encourage random
failures in the first place.
This type of communication
is the simplest and most basic
application of telematics.

parameters, and review updates provided by the OEM.

The next example goes a step
further by addressing a potentially catastrophic situation.
In this case, the driver receives
active communication and
suggestions on how to handle
the issue from the system.

the vehicle. It also generates automatic interventions, so the driver knows what is happening.
The engine itself detects a problem and executes
a protective routine to derate the power to extend
life (See Fig. 2). The driver then has the ability to
get to a location where the problem can be dealt
with correctly.
Finally, the system tells the driver to make
certain checks that might solve the problem. But
if not, it locates the nearest authorized service
center (See Fig. 3).
The system also informs the driver that it will
take some time for the "check engine" light to
turn off, once the system verifies the condition is
resolved (See Fig. 4).
There are several parts of this solution that
should be highlighted.
