B2.0 Driver Demonstration Mode

Selecting Demo from the main menu starts a demonstration mode that shows the various lights, display

screens, and sounds produced by the DIU – along with a brief explanation of their meaning – for the conﬁ gured

features. Pressing the down ( ) arrow button advances through the screens. The up ( ) arrow button has

no functionality in this mode. The mode may be exited at any time by pressing the OK button.

NOTE: This mode can only be entered while the vehicle is not moving. Also, while in the demonstration

mode, if the vehicle begins to move, the demonstration mode terminates.

If a screen is associated only with a conﬁ gurable feature, and that feature is not conﬁ gured, then that screen

will not be shown in the demonstration mode.

The screens presented to the driver in the demonstration mode are shown with the following text: “Error!

Reference source not found.”

B3.0 Following Distance Alerts (FDAs)

One of the features of the Bendix

Wingman

ACB system is the Following Distance Alert (FDA). A proprietary

system combining vehicle speed, forward vehicle speed, distance, and driving scenario, FDAs are used to

provide the driver with distance alerts which are intelligent, in that they will give appropriate distance alerts for

the given situation. They alert the driver to objects far ahead in highway and country road driving situations

while not over-alerting in dense city trafﬁ c.

The radar sensor uses the DIU to communicate the FDA alerts to the driver. This system can be conﬁ gured

through Bendix

ACom

Diagnostics software (version 6.3 or higher), for use by a ﬂ eet as a driver training

tool with or without coordinating the data made available by Wingman ACB. In addition to being a reminder

of when a driver may be dangerously close to the vehicle ahead, the following distance alerts may also be

conﬁ gured to reinforce safe following distance habits taught by the ﬂ eet.

The FDA is based on the following interval between the host vehicle and the object ahead. In other words,

this is the time required by the host vehicle to travel forward and reach the object’s current location. With the

exception of the volume, the FDA may not be adjusted by the driver through the DIU. A qualiﬁ ed technician

must connect to the vehicle through the diagnostic port and run ACom

Diagnostics (version 6.3 or higher),

in order to change the conﬁ guration. The volume can not be turned all the way down, but other adjustments

may be made by the ﬂ eet. See Section B1.3 for more details on volume adjustment.

The FDA system is intended only to alert the driver about following distance. For more information on alerts

for forward objects with high relative velocities and sudden decelerations, see Section B4.0: Impact Alert.

Only objects detected in the vehicle's lane, traveling in the same direction, are considered valid objects for the

FDA. For more information on stationary objects, see Section B5.0: Stationary Object Alert.

See Section 5.4: Conﬁ guring Bendix Wingman ACB Following Distance Alerts.

Appendix B

The driver is always responsible for the control and safe

operation of the vehicle at all times. The Bendix Wingman

ACB system does not replace the need for a skilled, alert

professional driver, reacting appropriately and in a timely

manner, and using safe driving practices.
