OnGuardALERT™ Forward Collision Warning System

The following information is for the OnGuardALERT radar-based active safety system that offers forward collision warning (FCW) and braking integration.

OnGuardALERT detects objects ahead and measures the vehicle’s position and speed in relation to other vehicles on the road to warn the driver of a possible collision by providing audible, visual and haptic warnings.

The system will provide a haptic brake pulse and begin to apply the brakes to reduce the severity of rearend collisions.

Safe Vehicle Operation

Multiple factors can affect set following intervals and create additional driving considerations. When operating a vehicle with the OnGuardALERT FCW with brake integration, it is important to remember:

• OnGuardALERT should only be considered as an aid and is not intended to replace driver control over the vehicle at any time.

• When operating the vehicle, always use safe driving techniques. The driver is always the most important element in safe vehicle operation.

• OnGuardALERT is only intended to assist reaction and response time. OnGuardALERT is not a substitute for proper driver braking and should only be considered a driver assistance system.

Unintended Events

The OnGuardALERT FCW is engineered to warn the driver of a potential collision threat so that the driver can react. Radar technology is not perfect; in every system it is possible that an unintended braking event may occur.

In the rare event that the driver experiences a false alert, or unintended braking event, they may experience the following sequence of events:

• Less than 0.4 seconds of braking.

• The vehicle brake lights will illuminate.

• The OnGuardALERT display screen will change to a collision warning (red).

• The OnGuardALERT display screen will change to a collision warning (red) and issue a short audible warning.

• The driver can reapply the throttle and continue driving the vehicle.

System Limitations

The OnGuardALERT FCW brakes for moving and stationary objects located directly in front of the vehicle and does not operate when your speed is less than 15 mph (24 km/h) or over 77 mph (124 km/h). Accordingly, OnGuardALERT:

• Will not react and alert the driver to objects crossing in front of the vehicle or oncoming traffic.

• Should not be relied on to track lead vehicles when traveling through a severe curve or winding road.

• Should not be relied upon to track smaller objects (motorcycles, mopeds, bicycles, pedestrians, etc.)

• Should not be relied on to alert drivers to vehicles in an adjacent lane.

Forward Collision Warning

The OnGuardALERT FCW system assists the driver in recognizing and responding to dangerous driving scenarios that could lead to a rear-end collision. The system responds by sending warnings, automatically reducing engine torque and providing some brake assistance through its integration.

OnGuardALERT’s FCW provides both visual and audible alerts through an in-cab dash display. If a potential collision is developing and the driver does not take action to decelerate the vehicle, OnGuardALERT’s brake integration feature issues a haptic warning (short brake pulse) and automatically dethrottles the engine. When OnGuardALERT begins brake integration, the brake lights will activate.

Operating Modes

Standard Driving Conditions

The OnGuardALERT FCW system will give audible and visual warnings when it detects a possible rear-end collision. FCW is active depending on settings from the manufacturer and will apply brakes if deemed necessary.

Collision Warning and Brake Integration

When an unforeseen event occurs, such as another vehicle entering the travel lane slower than you are, or the gap between you and a moving vehicle in front of you becomes too close, OnGuardALERT will provide an audible alert and the display will show a red outlined vehicle as shown in figure , ref. A.

If the system determines that a rear-end collision is imminent, it will automatically apply the brakes to reduce the vehicle’s speed. The driver may also feel a short brake pulse to warn them of a collision. The driver must also take the appropriate corrective action to avoid dangerous driving situations.

If OnGuardALERT detects a stationary object (such as a disabled car) it will provide an audible alert, followed by a haptic alert and then reducing engine torque and providing some brake assistance. FCW will not be active when vehicle speed is below 15 mph (24 km/h).

System Errors

If the driver receives an OnGuardALERT system error notification, the display will show a yellow icon indicating an error. See figure , ref. B. While your vehicle will still be operable, certain OnGuardALERT functions may not be available.

It is recommended that the driver find a safe place to park and turn off the ignition for approximately three minutes. While stopped, inspect the radar and clear any blockage. This will reboot the systems and may correct the error. If the condition persists, the driver should contact their local Freightliner dealer to review the issue. Any error information should be recorded for troubleshooting purposes.

Detroit Assurance Lane Departure Warning (LDW)

Safety Notes on Lane Departure Warning

The system may be impaired or may not operate in the following situations:

• There is low visibility due to insufficient road illumination, or due to snow, rain, fog, heavy spray, smoke, or other circumstances that limit visibility.

• There is glare due to oncoming traffic, direct sunlight, or reflections from wet road surfaces.

• The windshield in the area of the camera is dirty, misted up, damaged, or covered by a sticker.

• No lane markings or several varied lane markings are present, such as in a construction zone.

• The lane markings are worn, dark, or covered—such as by sand, dirt, or snow.

• The distance from the vehicle in front is too small and prevents the lane markings from being detected.

• The lane markings change rapidly, such as when lanes merge, branch off, or cross.

• Lanes are very narrow or winding.

• Shade conditions on the road surface vary widely.

The driver must adapt their driving style to current conditions. LDW cannot take the road and weather conditions into account, nor the prevailing traffic situation. The driver is responsible for the distance to the vehicle in front, for vehicle speed, braking in good time, and remaining in the lane.

Overview

LDW monitors the area in front of the vehicle using the multipurpose camera mounted at the top of the windshield. When LDW is active and detecting lane markings, it visually and audibly warns the driver if it thinks the vehicle may be leaving the lane unintentionally.

LDW only needs one identifiable lane line to function.

Functions and Activation Conditions for Lane Departure Warning

The Detroit Assurance LDW system is designed to warn the driver as the vehicle crosses the outer boundary of the lane marking. This may differ from other LDW systems which issue a warning as the driver approaches the inside of the lane marking. If the system warns at, or just beyond the outer edge of the lane marking, the system is performing as designed. If the warning does not occur, or occurs after an excessive lane departure, the system may not be operating properly.

Lane departure warning only issues warnings if the speed is above approximately 37 mph (60 km/h).

The lane markings on the driver display screen show the status and state of LDW:

• No lane markings indicate that LDW is off.

• Outlined lane markings indicate that LDW is not ready.

• Solid white markings indicate LDW is on and ready to issue warnings.

• Red lane markings indicate a lane departure is occurring; red lane markings are a visual warning from the LDW system.

In addition to the visual warning, when driving over lane markings unintentionally, the volume of audio equipment like the radio and/or hands-free systems is muted and a ‘rumble-strip noise’ emits from the side of the vehicle driving over the lane markings.

LDW does not issue an audible warning when:

• the turn signals are switched on

• if the driver is braking or accelerating

• if the driver is making a sharp turn

• if a driving safety system such as ABA, stability control, or ACC intervenes.

Activating or Deactivating Lane Departure Warning (LDW)

When the engine is turned on, LDW is automatically activated.

Pressing the LDW OFF switch deactivates LDW for fifteen minutes. The LDW OFF switch may be a physical dash switch, see figure , and/or a digital switch in the ICC5 infotainment panel under ’Digital Switches,’ see figure . When LDW is deactivated, the switch indicator illuminates.

A driver might want to turn off LDW on winding roads or when driving through construction zones or other areas where lane markings are not clear.

LDW is not active if:

• the driver presses the LDW OFF switch;

• the system is searching for a lane.

If there is a system error, the LDW unavailable telltale, see figure , illuminates on the driver display.

Cleaning the Windshield in the Area of the Camera

Make sure that the windshield is always kept clean and unobstructed in the area of the camera.

During rainy or cold weather, the driver should switch on the windshield wiper to clear the windshield and remove snow and ice to avoid incorrect lane detection.

If the area of the windshield is damaged, LDW may not work as intended. If this happens, the windshield must be replaced.

Detroit Assurance Active Lane Assist (ALA)

Active Lane Assist Safety Information

Features in ALA may become inactive under conditions where lane markings cannot clearly be identified. These conditions include:

• low visibility, due to insufficient road illumination or due to snow, rain, fog, smoke, or heavy spray;

• glare from oncoming traffic, the sun, or reflection from other vehicles when the road surface is wet;

• the windshield being dirty, misted up, damaged, or covered in the vicinity of the camera;

• the lane markings being unclear, such as in a construction zone;

• the lane markings being worn, dark, or covered;

• the distance to the vehicle in front being too small and preventing the lane markings from being detected;

• the lane markings changing quickly—lanes branching off, crossing one another, or merging;

• the road being narrow and winding;

• highly variable shade conditions on the road surface;

• an attachment (such as a snow plow) restricting the camera’s view of the lane markings;

• a significant change in load with the vehicle on. Start the vehicle after a significant change in load to have ALA available without restrictions.

ALA cannot take the road, weather conditions, or the current traffic situation into account. The driver is responsible for maintaining a safe distance to the vehicle in front, for vehicle speed, braking in good time, and remaining in the lane.

Active Lane Assist Overview

The LDW/LDP function of ALA detects lane markings on the road surface, warns the driver they may be leaving their lane unintentionally, and, if a driver does not respond to these warnings, moves the vehicle back into the center of the lane. If the driver’s preferred lane position is other than ’center,’ LKA will move the vehicle into the requested lane position after the LDP intervention is complete.

The LKA function of ALA uses micro-steering adjustments to keep the vehicle in the driver’s preferred lane position. It also monitor’s the driver’s steering, and if it senses the driver’s hand’s have been removed, cautions the driver to return their hands to the steering wheel.

Active Lane Assist Activation Conditions

ALA is activated each time the vehicle is turned on.

The LDW/LDP component of ALA is ready to issue warnings and initiate actions as soon as the vehicle reaches 37 mph (60 km/h) and both lane lines are identified and show on the driver display as solid lane markings. LDP requires both lane lines to be identifiable to function; LDW only requires one lane line to function.

LKA is ready to issue warnings and initiate actions when cruise control is active and when the vehicle is driving forward at approximately 15-20 mph (24-32 km/h).

The status of LKA is shown by the color and design of the steering wheel telltales on the driver display screen.

• Blue hands-on steering wheel: LKA is on and actively steering.

• Grey hands-on steering wheel: LKA is on but inactive (due to glare, snow, bad lane lines, etc.).

• Red hands-on steering wheel: auto stop is active.

• Amber steering wheel with exclamation point: There is a problem with the electro-hydraulic power steering system which deactivates LKA.

• Red steering wheel with exclamation point: There is an error with the adaptive power steering (APS) which deactivates LKA or an error with LKA.

• No steering wheel icon: LKA is off or deactivated.

See figure and figure for examples of an LKA status telltale in the driver display.

If the driver takes their hands off the steering wheel for fifteen seconds with Lane Keep Assist (LKA) active, an amber caution pop-up screen appears telling the driver to return their hands to the steering wheel. See figure . After hands are on the steering wheel, the pop-up disappears.

Active Lane Assist Functions and Warnings

ALA works to keep the vehicle within the lane, issues warnings when a driver takes their hands off the steering wheel, and if necessary intervenes to bring the vehicle to a safe stop.

With the driver’s hands on the steering wheel, the LKA feature of ALA engages in micro-steering adjustments to offset side winds, lateral road inclination, and other environmental forces to keep the vehicle in the driver’s preferred lane position. To set the preferred lane position, select ’Quick Access’ > ’Follow Distance/Lane Position.’ Options include:

offset to the right, offset to the left, or center. The default lane position is center.

If the micro-steering of LKA cannot compensate for the sideways movement of the vehicle and the vehicle crosses over the lane markings with no turn signal activation, LDW issues a warning as follows:

• The exceeded lane markings appear in red on the driver display screen.

• The volume of the audio equipment and/or hands-free system is muted.

• A warning rumble strip sound is broadcast from the speaker on the side of the exceeded lane markings.

If the driver does not steer the vehicle back into the lane or activate a turn signal, a warning notification appears on the driver display and LDP intervenes. An acoustic warning sounds while LDP guides the vehicle back into the center of the lane.

LDW does not issue a warning about traveling over lane markings if:

• a turn signal is switched on;

• a driving safety system, such as ABA, stability control, or ACC intervenes.

LDW only issues a visual warning about traveling over lane markings if the driver is braking, accelerating, or making a sharp turn.

In addition to helping keep the vehicle in the desired lane position, LKA monitors the driver’s hands on the steering wheel. If LKA senses the driver’s hands are not on the steering wheel, it issues a series of warnings.

If LKA is active and the driver takes their hands off the steering wheel for 15 seconds, an amber caution pop-up window appears telling the driver to return their hands to the steering wheel. Doing so will cause the pop-up window to disappear. See the figure .

If the driver does not return their hands to the steering wheel, at 30 seconds a red warning pop-up window appears and an acoustical warning starts to sound every five seconds.

If the driver does not return their hands to the steering wheel, at 55 seconds the acoustical warning starts to sound every second.

If the driver does not return their hands to the steering wheel, at 60 seconds the acoustical warning becomes a continuous loud audible warning.

As soon as the driver places their hands on the steering wheel, the LKA visual and audible warnings cease and the hands-off count is reset to zero.

LKA becomes inactive when the driver activates a turn signal.

LKA deactivates with the intervention of LDW/LDP, the deactivation of ACC, and if deactivated by the driver.

Active Lane Assist (ALA) Switches

In a vehicle equipped with an ICC5, there are four possible switches related to active lane assist (ALA): two digital and two physical:

• A physical LDW off switch, shown in figure .

• A digital LDW off switch, shown in figure .

Pressing either a physical or digital LKA OFF switch turns off LKA for the key cycle. The switch light illuminates to show that LKA is off. Pressing the switch or restarting the vehicle turns LKA on.

A driver might want to turn off LDW on winding roads or when driving through construction zones or other areas where lane markings are not clear.
