the vehicle’s brakes. The driver must apply additional braking, when necessary, in order to maintain a safe
distance from the vehicle ahead.

E4.1 Collision Mitigation Braking (CMB)
If a collision is likely to occur, and the collision mitigation feature activates the foundation brakes, the tone
of the alert will typically change and the display will be as shown below. The driver must immediately act to
potentially avoid, or lessen the severity of, a collision.

E5.0 Stationary Object Alert (SOA)
Stationary Object Alert (SOA) is an alert given to the driver when the radar detects a sizeable, non-moving
metallic object in the vehicle's path of travel. To reduce the number of false detections, such as bridges and
overhead signs, a set of filters are put in place so the SOA will not warn on every stationary object. Typically
the SOA is ready to alert the driver whenever the vehicle is moving above ten (10) mph / 16 kph, but some OEs/
fleets may select higher minimum speeds.
The SOA can be configured to be on or off through the display.
If a SOA is issued – up to three (3) seconds before a potential impact – the DIU will very briefly send out an
alert identical to a very brief FDA Level 2: continuous tone and two (2) yellow LEDs, with the display image
switching between the two shown below.

E6.0 Stationary Vehicle Braking (SVB) Alert

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, Wingman
Fusion 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; 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, but although that figure is
typical, some OEs/fleets may select higher minimum speeds. The driver should be especially careful when approaching
certain types of vehicles or objects. The Bendix® Wingman® 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.

E7.0 ACB (Active Cruise Control with Braking) Icon
The ACB icon appears in the upper left-hand corner of the DIU’s screen to indicate to the driver that the active

Once the driver sets cruise, the DIU will display the set speed and the ACB icon as shown below.

system is still engaged and ready to intervene.

E8.0 Brake Overuse Alert

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.
Call the Bendix Tech Team at 1‑800‑AIR‑BRAKE (1‑800‑247-2725), option 2, for troubleshooting assistance.

Cruise Control should NOT be used on downhill grades. Grades should be approached normally, with the
appropriate gear selected and at a safe speed.
To guard against foundation brake overuse by the active cruise control with braking feature of the Bendix® Wingman®
Fusion™ system, the frequency of foundation brake interventions is monitored. If the system detects a situation where
the brakes are being applied too frequently by the system in a given time period, the brake overuse alert will activate.
This is designed to help prevent overheating of the brakes, which may lead to brake fade and reduced vehicle braking
capability. In this situation, the Brake Overuse Alert (BOA) will flash a message requesting driver intervention. Also, an
audible alert will sound and a blue LED will blink on the Bendix Driver Interface Unit (DIU™), as illustrated below:

This alert will continue for 15 seconds, during which time the driver should step on the brake or turn off cruise
control using the cruise control on/off switch.

WARNING: After a BOA, for a period of time (typically 20 minutes), the Wingman
Fusion system will not use the foundation brakes when intervening. The system
will be limited to de-throttling the engine and applying the engine retarder. 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.

•

The time period for this mode is measured from the time the BOA was activated and lasts
approximately 20 minutes.

•

NOTE: The driver will continue to receive all three alerts (Following Distance, Impact, and
Stationary Object).

•

Additionally, the DIU message will change to “ACB Braking Overuse” and the blue LED will
remain lit, as shown below:
