K1.9 HOW A DRIVER INTERACTS WITH THE BENDIX® WINGMAN® FUSION™ SYSTEM
Table K2 illustrates how the Bendix® Wingman® Fusion™ system will respond to various actions a driver may take when
using the Fusion system on the road.

The driver is always responsible for the control and safe operation of the vehicle at all times. The Bendix
Wingman Fusion system does not replace the need for a skilled, alert professional driver, reacting appropriately
and in a timely manner, and using safe driving practices.

How a Driver Interacts with the Bendix Wingman Fusion System (1.4)
If the driver does this:

Expect the Wingman Fusion system to do this:

Steps on the brake. (During a collision
mitigation event.)

The driver is always in control and is able to apply full braking power.

Steps aggressively on the accelerator.
(During a collision mitigation event.)

The driver is always in control. His/her actions override any Fusion
system actions. Note: If cruise control is engaged, it will be overridden
until the accelerator is released; then cruise control will resume the
original set speed automatically.

Steps on the brake. (When in cruise.)

Cruise control will be cancelled.

Steps on the accelerator.
(When in cruise.)

Cruise control will be overridden until the accelerator is released; then
cruise control will resume the original set speed automatically.

Switches on the cruise control.

Nothing. The active cruise control with braking feature will not engage
until the driver sets the cruise control speed.

Switches off the cruise control.

The active cruise control with braking feature will turn off; the collision
mitigation feature remains active and ready to intervene. The driver will
continue to hear all alerts as needed.

Sets the cruise control speed.

The active cruise control with braking feature is automatically activated.
The vehicle maintains a set speed and following distance behind the
vehicle ahead.

Covers or blocks the radar.

The Bendix Wingman Fusion system performance will be diminished or
even disabled when the radar is blocked. An audible and/or visual alert
will notify the driver of this condition. The driver should remove the radar
blockage and the Wingman system performance will return to normal.

Uses normal cruise control “+/-” switch.

Vehicle speed increased (+) or reduced (-) to achieve the new set speed
while actively maintaining following distance with the vehicle ahead, if one
is present within 500 feet (152 m).

Presses the Lane Departure Warning
(LDW) enable/disable switch.

The LDW system alerts will be suppressed for 15 minutes.

THE FORWARD VEHICLE DETECTED ICON
When cruise control is switched on and set, and a vehicle
ahead is detected by the radar, the detected forward vehicle
icon – or similar – will illuminate on the vehicle dashboard.
This is an indication to the driver that the Bendix Wingman®
Fusion™ system is actively managing the distance between
the driver and the forward vehicle, and may intervene
automatically, if needed.

K1.11 LANE DEPARTURE WARNING
DIU STATUS SCREEN ICONS
See Figure K11. In the case of vehicles that use a Bendix™
Driver Interface Unit (DIU™), the top right corner of the
display is used to show an icon. For other OEM displays,
see the vehicle manual to find the method used to show
the system status.
During Start-Up – System Busy

See Figure K10 for examples.

The first symbol shows when the LDW
system is initializing.
Normal Operation
The LDW system is actively seeking
lane-markings.

ADJUSTING THE CRUISE CONTROL SPEED

This symbol appears when the LDW
system is actively tracking lanemarkings on both sides of the current
lane.

The vehicles' cruise control speed can be set using the
switch(es) provided by the vehicle manufacturer. When
adjusted, the set speed will typically be indicated on the
vehicle dash, message center, or speedometer.

This symbol indicates that the system
is currently tracking lane-markings on
the left only.

Figure K10 - Forward Vehicle Detected Icons

K1.10 FOLLOWING DISTANCE
Following distance refers to the time gap, measured in
seconds, between the driver and the vehicle ahead. The
actual physical distance between the two will vary based
on the speeds of both vehicles; however, the set gap will
remain the same for all set cruise speeds.

FOLLOWING DISTANCE
ADJUSTMENT SWITCH
This Wingman Fusion system feature has an option
that allows the driver to adjust the following-distance
or time‑gap. Feature availability is determined by the
vehicle manufacturer. The switch has an increase or
decrease function. Pressing increase (+) will provide a
larger following distance, measured in seconds. Pressing
decrease (-) will provide a shorter following distance.

This symbol indicates that the system
is currently tracking lane-markings on
the right only.

System Status

If none of the LDW status icons shown in Figure K11 appear
on the DIU screen – and the driver has not pressed the
LDW disable switch (see Section 2.3) – this indicates that
the system using the Bendix™ AutoVue® FLC-20™ camera
has detected a DTC and the system should be serviced
at the earliest opportunity. See Figure K12.
DTC Set
If no LDW status symbol is shown
– and the driver has not applied the
LDW disable switch – this indicates
that the system has detected a DTC.

K1.12 BENDIX® WINGMAN® FUSION™
SYSTEM COLLISION MITIGATION
FEATURE OPERATION

IMPACT ALERT (IA)/
COLLISION MITIGATION BRAKING (CMB)

Whenever the vehicle is traveling above 15 mph / 24 kph,
the Bendix® Wingman® Fusion™ system collision mitigation
feature is ready to intervene, if needed. It does not
require cruise control to be set. The collision mitigation
feature of the Wingman Fusion system will alert the driver
automatically, and apply the vehicle’s brakes if a collision
with the detected forward vehicle is likely to occur. The
driver must immediately act to potentially avoid, or lessen
the severity of, a collision.
Collision mitigation is ready to intervene as long as no DTCs
are active in either the brake system, the Fusion system,
or any other contributing vehicle system.

AUTOMATIC FOUNDATION
BRAKE APPLICATIONS
The vehicle automatically manages foundation braking
priorities among the various vehicle systems that use the
foundation brakes, such as the Bendix Wingman Fusion
system, Bendix® ESP® (Electronic Stability Program),
Bendix® ATC (Automatic Traction Control), and Bendix®
ABS (Antilock Braking System).

K1.13 ALERTS AND WARNINGS

The Impact Alert (IA)/Collision Mitigation Braking
(CMB) is the most severe warning issued by the
Bendix Wingman Fusion system. This alert indicates
that a collision with the detected forward vehicle
is likely and the driver must immediately act to
potentially mitigate, or lessen the severity of, a
collision.
The IA/CMB is ready to alert the driver whenever the
vehicle is moving above 15 mph / 24 kph.
When activated, the IA/CMB will sound and a visual
message/icon typically appears on the dash screen or
Bendix™ Driver Interface Unit (DIU™) display. The actual
sound/display method varies by vehicle manufacturer.
NOTE: The IA/CMB is typically accompanied by automatic
brake interventions. The Fusion system will apply the
vehicle’s brakes. The driver must apply additional braking,
when necessary, to maintain a safe distance from the
vehicle ahead.
See Figure K13 for an example of an Impact Alert Icon.

The Fusion system operates differently compared to other
cruise control/forward collision warning systems. It is
important that the driver fully understands the system’s
features, especially the alerts and warnings.
Three important warnings provided by the Bendix Wingman
Fusion system are the Following Distance Alert (FDA),
Impact Alert (IA), and Stationary Object Alert (SOA). The
driver will be alerted by any of the three warnings, whether
or not the cruise control is activated.
See Appendix B, Sections 3.0–5.0, for more information
about how DIUs communicate alerts.
Figure K13 – Example of Impact Alert Icon

All Red LEDs Illuminated

Any audible and/or visual alert by the system
means that the vehicle is too close to the vehicle
or object ahead, and the driver must immediately
act to potentially avoid, or lessen the severity of, a
collision.

FOLLOWING DISTANCE ALERT (FDA)
Object Detected

The FDA is ready to alert
the driver whenever the
time between the vehicle
and the detected forward
vehicle is less than oneand-a-half (1.5) seconds*
and decreasing. Once the
audible alert is given, the
driver should increase the
distance between his/her
vehicle and the vehicle
ahead until the audible
alert stops.

Object Detected

STATIONARY OBJECT ALERT (SOA)

Stationary Object Alert (SOA) – The Bendix® Wingman®
Fusion™ system will give up to a three (3) second
alert to the driver when approaching a detected,
sizable, metallic (radar-reflective), stationary object
in the same lane of travel. This alert indicates that
a collision with a stationary object is likely and the
driver must immediately act to potentially avoid, or
lessen the severity of, a collision.

Object Detected

The FDA is ready to alert
the driver whenever the
vehicle is moving above
5 mph / 8 kph.

continues to decrease, the
driver will hear more rapid
audible alerts. When the
FDA reaches its highest
level, typically a red LED
also illuminates on the
instrument cluster. The
FDA may be accompanied
by a visual alert.

The SOA is ready to alert the driver whenever the vehicle
is moving above 10 mph / 16 kph. The driver should be
especially careful when approaching certain types of
vehicles or objects. The Fusion system radar may not be
able to detect 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.

STATIONARY VEHICLE BRAKING (SVB)

BRAKE OVERUSE ALERT

Stationary Vehicle Braking (SVB) – When a large,
stationary, metallic object in a vehicle’s lane of
travel is definitively identified as a vehicle, the driver
is notified up to 3.5 seconds before impact. If the
driver does not take action to address the potential
impact that caused the alert, the Bendix® Wingman®
Fusion™ system can automatically engage the brakes
to assist the driver in reducing the severity of or
potentially avoiding a collision with that stationary
vehicle. If the system cannot definitively identify
the stationary object as a vehicle — for example, if
the vehicle is not a licensed motorized vehicle, or
certain types of trailers — the driver will get up to
3.0 seconds of alert to address the situation ahead,
but no automatic braking will be applied. Stationary
Vehicle Braking is most useful when approaching a
line of stopped traffic or a stalled vehicle that is not
immediately recognized by the driver.

The SVB is ready to alert the driver whenever the vehicle
is moving above 15 mph / 24 kph. The driver should be
especially careful when approaching certain types of
vehicles or objects. The Fusion system radar may not be
able to detect vehicles with limited metal surfaces (such as
recreational vehicles, horse-drawn buggies, motorcycles,
logging trailers, etc.). NOTE: Entering a curve may reduce
the alert time.

The Bendix Wingman Fusion 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.

Grades should be approached 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 K18 – 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.

DRIVER INTERVENTION

Figure K17 – Stationary Vehicle Braking (SVB) Alert Displayed

If the driver chooses to reset cruise control during that
20 minute period, Fusion system interventions will
be limited to de-throttling and engine retarder only.
The system will automatically disable all Wingman
Fusion 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 Fusion
system interventions (de-throttling, engine retarder
or brake applications) will be disabled until the next
ignition cycle.

Appendix K

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).

The Bendix Wingman Fusion system has the ability to
warn the driver if the vehicle’s speed exceeds the posted
legal limits. The Overspeed Alert & Action is enabled
when the vehicle is traveling greater than 5 mph / 8 kph
from the posted limit. The driver should immediately
reduce speed to the posted legal limit.

LANE DEPARTURE WARNING
(LDW) ALERT

The Bendix® Wingman® Fusion™ system has the ability
to warn the driver if the vehicle is not tracking in the
intended roadway path. In most vehicle applications the
LDW system is enabled above 37 mph. The driver should
immediately correct the vehicle tracking and maintain the
correct position in the lane.
