BENDIX Intellipark Service Data page 3

Proper integration of the Intellipark EPB system by
the vehicle OEM provides the following vehicle driver
assistance functions:
• Assists in mitigating driver error of leaving the vehicle
unparked while not present to control the vehicle
• Assists in mitigating driver error of attempting to unpark
while not in control of the vehicle
• Reduces the likelihood of damage in a drive-away with
the trailer parking brakes applied (Auto Trailer Brake
Release – if enabled [refer to the vehicle manufacturer])
The Bendix Intellipark
®
(EPB) system cannot detect issues with other
components of the park brake system, such as the
spring brake chambers. Accordingly, drivers and
maintenance personnel must perform inspections and
maintenance on the park brake system in accordance
with established procedures. For proper operation of
the Intellipark EPB system, all other components of the
park brake system must be functioning as designed.
Improper use of the Intellipark EPB system can result
in an unsafe park state, causing property damage,
serious injuries, or death. Drivers must be responsible
for the safe operation of the vehicle at all times. The
Intellipark EPB system does not replace the need for
a skilled driver, reacting appropriately and in a timely
manner, and using safe driving practices.

VEHICLE OPERATION FEATURES
NOTE: Refer to the applicable operator's manual on
B2Bendix.com for further details on vehicle features and
interlocks.
• Towing Vehicle: Single-Button Park: The Intellipark
EPB system provides the ability to park all units of a
combination vehicle with a single input. This feature is
similar to the single-button park feature of the Bendix
MV-3 dash control valve. Upon pulling the yellow
®
switch of the Dash Electronic Control Unit (DECU), the
Park Valve Module (PVM) will exhaust the air from the
power unit and towed unit channels. The behavior of
this feature is modified if the vehicle is moving. See
the section titled Exhaust-at-Speed for more details.
• Towing Vehicle: Independent Trailer Air Control: The
Intellipark EPB system provides the ability to charge
or evacuate the trailer supply (red) line independent of
the state of the power unit spring brakes. This feature
allows operation of a vehicle with towing provisions
as a solo vehicle, supports coupling and uncoupling
operations, and allows trailer emergency brake control.
Upon pulling the red switch of the DECU, the PVM
will exhaust the air from the towed unit channel, with
no change in state of the power unit (yellow) channel.
Upon pushing the red switch of the DECU, if the trailer
air charge interlocks have been satisfied, the PVM will
deliver air to the towed unit channel, with no change
in state of the power unit (yellow) channel.
• Towing Vehicle: Independent Trailer Air Charge
Interlock: The Intellipark EPB system provides the
ability to restrict the air charge function of the trailer
based on inputs from the vehicle, including the service
brakes and ignition switch. This feature is intended to
help mitigate the possibility of release of the trailer park
brakes without a driver in control of the vehicle, while
allowing the trailer(s) to be charged with the power
unit parked. This functionality supports coupling and
PRO
™
uncoupling operations, including pre-trip inspections
for some types of combination vehicles.
