Bendix Commercial Vehicle Systems WINGMAN ACB ACTIVE CRUISE W/BRAKING - Manual (Page 10)

10
The driver should be especially careful when approaching
certain types of vehicles or objects. The Wingman ACB
radar may not be able to detect vehicles and objects with
limited metal surfaces (such as recreational vehicles,
horse-drawn buggies, motorcycles, logging trailers, etc.).
NOTE: Entering a curve may reduce the alert time to less
than three (3) seconds.
FIGURE 11 - STATIONARY OBJECT ALERT DISPLAYED
BRAKE OVERUSE ALERT
The Bendix ® Wingman ® ACB system provides a
warning when the system is intervening and using
the foundation brakes excessively. Overuse of the
foundation brakes can lead to the brakes overheating
and a potential loss of braking performance caused
by brake fade.
Using cruise control on downhill runs will
cause this alert to be activated.
Approach grades as you would normally, with the
appropriate gear selected and at a safe speed. Cruise
control should NOT be used on downhill grades.
When the system detects brake overuse, depending on the
vehicle manufacturer, a text message will be displayed on
the dashboard and an audible alert will be activated. The
driver should intervene immediately.
FIGURE 12 - BRAKE OVERUSE WARNING
• Once the brake overuse alert is activated, certain
driver interventions that cancel cruise control – like
stepping on the brake pedal or switching off cruise – will
discontinue the alert. Following an overuse alert, the
driver should not reset cruise control for at least 20
minutes. This gives the brakes time to cool down. If
the driver chooses to reset cruise control during that
20 minute period, Wingman ACB interventions will be
limited to de-throttling and engine retarder only. The
system will automatically disable all Wingman ACB
system foundation brake applications for at least 20
minutes.
• If the system does not detect a driver intervention within
15 seconds after the brake overuse alert sounds, it
will shut itself off and set a Diagnostic Trouble Code
(DTC). The driver will continue to receive alerts, but
ALL Wingman ACB interventions (de-throttling, engine
retarder or brake applications) will be disabled until the
next ignition cycle.
Note: In all cases, the driver still has the ability to
apply the foundation brakes if necessary. The driver
should take care since overheated brakes may reduce
the vehicle’s braking capability.
(See Appendix B7.0).
1.09 WINGMAN ACB DIAGNOSTIC
TROUBLE CODES
The Wingman ACB system is monitored and if any
malfunction is detected, a Diagnostic Trouble Code (DTC)
will be set and the driver will be alerted. The exact alert
given depends on the vehicle manufacturer: refer to your
vehicle operator’s manual and Sections 3 and 4.
1.10 RADAR SENSOR INTERCHANGEABILITY
Many variables must be considered when determining
whether or not the radar sensor can be relocated from one
vehicle to another vehicle. They include, but are not limited
to, the version of the Bendix
® ESP ® stability system used
on the vehicle, the instrument cluster, the vehicle ECU, the
engine and the transmission. Contact the Bendix Tech Team
at 1-800-AIR-BRAKE to determine if this is a viable option.
WARNING: Do not interchange radar sensors
without contacting Bendix
fi rst!
1.11 ALERT VOLUME
For Wingman ACB systems installed on vehicles with alerts
that come directly through the instrument cluster, audible
alert levels are pre-set at the factory and can not be turned
off, nor can the volume be adjusted. However, where
the Bendix
® Driver Interface Unit (DIU) is used, volume
adjustment is permitted.
1.12 POTENTIAL FALSE WARNINGS
In certain unusual traffi c or roadway conditions, Wingman
ACB may issue a false alert. While eliminating all false alerts
is not possible, if false alerts occur too frequently (more
than twice a day), this may indicate sensor misalignment.
Service the system at the earliest opportunity.
Drivers should take into account the road conditions, and
any other factors they are encountering, as they choose
how to react to any alerts they receive from the Wingman
ACB system.
