ICUC Vehicle Operations: Vehicle
Settings
The ICUC Vehicle Operations menu has a submenu
called Vehicle Settings. Settings and controls for ve-
hicle features installed on the vehicle can be found
here. These may include:
•
Cruise Control (See Fig. 3.19 .)
•
Transmission (See Fig. 3.20 .)
•
Attention Assist
•
Engine Idle Adjust (See Fig. 3.21 .)
•
Optimized Idle
See Fig. 3.13 . Many of these may also be accessible
under the Quick Access Systems menu.
Cruise Control
Settings for cruise control include setting the over-
speed and underspeed in mph or kph and setting the
following distance in seconds. For full instructions on
standard Cruise Control, see
Chapter 7 Driver Assis-
tance Features.
Transmission
The Transmission vehicle settings menu allows the
driver to turn Creep Mode and eCoast on or off.
Creep mode is a DT12 Transmission feature that
helps the driver move the vehicle at slow speeds by
slipping the clutch to reduce torque to the wheels. It
is designed to improve maneuverability in situations
like parking, docking, and slow traffic.
To activate Creep mode for the first time within the
current driving cycle, press the accelerator pedal to
launch the vehicle, thereby fully engaging the clutch.
Stopping the vehicle with the service brake will not
cause the vehicle to exit Creep Mode. While in
Creep Mode, a lower gear may be selected and the
transmission can be upshifted or downshifted with
the shifter stalk.
The eCoast feature is standard on DT12 engines. On
a downslope the clutch will momentarily disengage
so the vehicle maintains momentum while the engine
idles. Engine rpms will drop to 600 in eCoast mode.
Input from the driver will cause the vehicle to exit
eCoast mode.
For a fuller coverage of Creep and eCoast mode see
Chapter 17 Automated and Automatic Transmis-
sions.
Attention Assist
The Attention Assist feature is intended to support
the driver by calling attention to drowsy driving be-
havior and thereby encouraging rest.
The Attention Assist feature estimates the driver’s
attention level based on lane keeping and steering
behavior and activity levels in using turn signals, re-
tarder, and kick down operations.
When attention levels drop below a certain threshold,
an audible warning will sound, a visual warning will
appear on the ICU, and lane departure warnings will
be activated if previously disabled.
Engine Idle Adjust
This feature allows the increase or decrease of the
base engine idle speed. Increasing the base engine
idle might be necessary to generate enough power to
operate accessories.
The following conditions must be met to the engine
idle speed to be adjusted:
•
Engine is running
•
Vehicle is at a standstill
•
Transmission is in neutral
Optimized Idle
Optimized Idle reduces idle time by automatically
stopping and restarting the engine. Besides saving
fuel, it helps keep the batteries charged while main-
taining engine and cab temperature.
The following conditions must be met for the opti-
mized idle to function:
•
Vehicle in neutral gear
•
Park brake set
•
