Active Brake Assist 5 (ABA5)

47x d 05.01.002

Overview

Important: The windshield must be clean, unobstructed, and without damage for proper operation of the multipurpose camera. No objects or attachments should be mounted in front of the forward radar and the radar covering should be free of paint, stickers, mud, ice, or snow.

ABA is active when the vehicle is on.

ABA5 uses fused camera and radar signals for improved object recognition, enabling it, in some cases, to recognize potential hazardous situations faster than a driver. If the camera system becomes temporarily disabled, radar signals alone are used.

Active Brake Assist 5 tracks both moving and stationary objects in the vehicle's path and engages in a cascade of actions. ABA5 has the capacity to engage full braking on slower moving vehicles, moving pedestrians, parked vehicles, and stopped traffic as follows:

visual and auditory warnings;
then partial braking;
then full or emergency braking.

ABA5 has the capacity to engage full braking on slower moving vehicles, moving pedestrians, parked vehicles, and stopped traffic. The system may not detect pedestrians or objects in every situation, nor is it a substitute for cautious driving.

Safety Information

Warning: Active Brake Assist 5 (ABA5) is intended only as an aid for a conscientious and alert driver. The driver is responsible for keeping a safe distance from the vehicle in front, for the vehicle speed, braking in good time, and remaining in lane.

ABA5 does not take road and weather conditions into account, nor the prevailing traffic situation. The driver should always adapt driving style to suit prevailing road and weather conditions.

ABA5 is not a substitute for safe driving procedures.

Operate a vehicle equipped with Detroit Assurance Collision Mitigation System as if the vehicle were not equipped with a collision mitigation system.

The Detroit Assurance Collision Mitigation System will not warn of hazards such as animals, oncoming vehicles, or cross traffic.

Failure to drive safely and use the system properly could result in personal injury and/or death and severe property damage.

If your vehicle is equipped with ABA5 it can:

react more quickly than a driver to an object in the vehicle's path of travel;
perform emergency braking; and
react to moving people with a warning and partial and full braking.

Detroit Assurance ABA5 can minimize the risk of a front-end collision with a moving or stationary vehicle and pedestrians. If ABA5 detects the risk of a front-end collision, it issues an audible and visual warning. If the risk persists, ABA5 automatically initiates partial braking of the vehicle. If the driver does not react to the warnings and partial brake application, ABA5 automatically initiates a full brake application.

ABA5 may also detect people who are moving along the edge of the lane.

ABA5 may not detect vehicles driving in a different lane or narrow vehicles, like motorcycles, driving in front of the vehicle.

Brake the vehicle using the service brake if:

an event window with the warning symbol appears on the driver display screen;
an intermittent warning tone sounds; or
an intermittent warning tone sounds and automatic partial braking is initiated.

ABA5 does not automatically adapt to road and traffic conditions. If no visual and/or acoustic warning is issued in a critical situation:

ABA5 has not recognized the danger of the situation;
ABA5 is suppressed; or
ABA5 has failed.

Activating and Deactivating Active Brake Assist

Models made January 2023 and after are equipped with an ABA OFF physical switch option, to support specific operations where an ABA false positive may occur, or conditions where the ABA activation is not required. See Fig..

Fig. 1, ABA OFF Switch

When the ABA function is turned off by the driver the physical switch LED logo illuminates in red, and the ICUC presents a popup warning to the driver showing the ABA not available status. See Fig..

The ABA remains off until the driver deactivates the switch, or after a complete key cycle turns the ABA feature back ON.

Active Brake Assist 5 (ABA5) Collision Warning and Emergency Braking

If there is a risk of collision, ABA5 issues alerts on the driver display, illuminates the ABA indicator lamp, and sounds an audible warning. In addition, the radio and/or hands-free systems like Detroit Connect are automatically muted.

Note: A driver can override ABA during an ABA braking event by backing off the accelerator pedal, then pressing the accelerator pedal to the floor.

If there is a collision risk, ABA engages in the following cascade of warnings:

Issues Warnings : the radio and/or hands free system is muted, the vehicle issues a warning beeping, and an ABA collision warning window, shown in Fig. appears on the driver display.

Fig. 3, First Visual ABA Warning, ICUC
Engages in Partial Braking : ABA brakes the vehicle with around 50 percent of the vehicle's maximum braking power.

The radio and/or hands free system stays muted, the warning beeping continues, and the ABA collision warning, shown in Fig.. continues to appear or, if previously dismissed, reappears on the driver display.
Engages in Emergency Braking : If a driver does not react to the collision warnings or partial brake application, ABA brakes the vehicle with 100 percent of the vehicle's maximum braking power.

The radio and/or hands free system stays muted, the warning beeping shifts to a continuous tone, and the emergency braking warning, shown in Fig. appears on the driver display.

Fig. 4, Second Visual ABA Warning, ICUC
Brakes Release : The radio and/or hands free system is taken off mute, the warning tone ceases, and the notice shown in Fig. appears on the driver display.

The driver should take the first opportunity to safely move the vehicle from traffic. Before continuing, the driver should confirm that the vehicle is in good operating condition and that the load is still properly secured.

Caution: After an emergency braking maneuver has been performed, if necessary, move the vehicle from the area of danger.

Take the first opportunity to safely move the vehicle from traffic to confirm the load is still properly secured and that the vehicle is still in good operating order. Failure to do so may result in personal injury and product or property damage

Always apply the parking brake prior to exiting the vehicle.

ACC and ABA5 Driving Condition Limitations

See Table. for a description of adaptive cruise control (ACC) and ABA5 limitations in specific driving conditions.
