Overview of the Reverse Smart AEB
The Reverse Smart Autonomous Emergency Braking (AEB) device is designed to reduce
incidents of large vehicles impacting workers, members of the public or objects whilst
reversing manoeuvres are taking place.
The Reverse Smart system will only operate once the vehicle is placed in reverse gear.
When the system radar sensors detect a worker/member of the public or an object that is
within the danger zone behind the vehicle, the unit will immediately and automatically
activate the vehicle brakes –without any driver input required.
This device actively protects the vehicle and personnel working at the rear of the vehicle
without interfering with the vehicles’intended daily operation.
The driver should complete all required checks to ensure there are no persons or objects
behind the vehicle prior to reversing.

REVERSE SMART AEB.
NOTE: The Reverse Smart system is only in operation when the vehicle is in
“reverse gear”. The only way to deactivate the entire system is to take the vehicle
out of reverse gear.
ACTIVATING THE REVERSE SMART SYSTEM
When the vehicle is started the Reverse Smart system will sound an audible alarm and red
flashing lights will be displayed to indicate the system has been turned on, at this stage the system
has NOT been activated.
To activate the Reverse Smart system the driver must place the vehicle in reverse gear; green
lights on the display unit will indicate the system has now been activated.
HOW THE REVERSE SMART SYSTEM WORKS
When the Radar located on the rear of the vehicle detects a person/object within the rear danger
zone, the Reverse Smart system will automatically apply the vehicle brakes. The vehicle brakes
will only be held for a short period of time (approximately 3-5 seconds); at the same time the visual
display and audible proximity alarms (See Radar Operation Section 4) located in the cabin will be
alerting the driver to the presence of a person/object behind the vehicle. The closer the vehicle
comes to the person/object the more insistent the audible proximity alarm sounds and the brighter
the flashing lights on the display unit.
The driver should park the vehicle and make it safe before exiting the cabin to complete a visual
check of the surrounding area. Once the area is clear the driver may continue the task. Once the
vehicle is placed in reverse gear the Reverse Smart system is again activated.
Note: Once the short period of time outlined above has elapsed, the vehicle brakes will be
released, and the driver is able to continue the reversing manoeuvre. The visual display and
audible proximity alarms will continue to alert the driver of the presence of the person/object
behind the vehicle.
WARNING: the brakes will not be automatically applied again whilst the person or objects
are still being detected by the radar.
For the brakes to automatically apply again, any person/objects must be removed from the
detection zone –ensuring the visual display and audible proximity alarms aren’t sending any
warning alarms, and NEW persons/objects have entered the detection zone.

SLEEP MODE OPERATION
In situations where the driver is fully aware of the person/object behind the vehicle, for example,
trailer, waste disposal bins etc. and does not want the vehicle brakes to automatically apply, the
“braking”component of the Reverse Smart system can be put into a timed “Sleep” mode (30
seconds –2 minutes) by depressing the LARGE RED BUTTON on the visual display (as shown
below). In “Sleep”mode the visual display and audible proximity alarms will still operate whilst
the vehicle is in reverse, but the brakes will not be applied until the “Sleep” mode timer has
expired.
“Sleep”mode can be activated at any time during a reversing manoeuvre.
The LARGE RED BUTTON will “Flash” whilst they system is in SLEEP MODE.
Example of “Sleep” Mode –Large Red Button.

RADAR OPERATION
1 Introduction
The Radar utilises FMCW (Frequency Modulated Continuous Wave) radar system technology
and is designed to detect people and objects in blind spots, significantlyreducing collisions. They
detect stationary and moving objects, providing the driver with in-cab visual and audible warnings
–alerting the driver whose attention cannot be focused on all risk areas. The Radar works
effectively in harsh environments and in poor visibility including darkness, smoke, fog and dust.
Drivers of the vehicle to which the Reverse Smart system is fitted must be made fully aware of
how to interpret the system so they will not be distracted by or rely completely on it. Distraction
can cause collisions.
The system is intended as an aid only. The driver must still concentrate on driving the vehicle,
obeying all traffic and local regulations and continuing to use his/her own training, senses and
other vehicle aids, such as mirrors, as if the system were not in place. Nothing removes the
responsibility of the driver to operate the vehicle in a proper and lawful manner.
2. Object Detection Capability
The radar is detecting objects beyond the immediate danger zone behind the vehicle.
On some occasions objects beyond the immediate danger zone may actually set off the
systems alarm, and will apply the vehicles brakes.
There is no detection of objects or part of an object closer than approx. 0.3m to the sensor.
Object detection between approx. 0.3m to 1.3m from the sensor requires a minimum relative
speed of around 2km/h between the object and sensor. Same for re- detection of objects after
a stationary condition.
The radar beam angle has a 120° horizontal angleout to the maximum designated width. The
vertical angle is 12°. Both angles are symmetrically perpendicular to the sensor front surface.
All dimensions for detection of objects are nominal and vary significantly depending on many
parameters. For more details, see Section 3 “Factors Influencing the Detection of Objects”
below.
An object will cause a detection alert in less than 0.5 second.
After turning on the power the system takes around 6 secondsto be active. Timefrom standby
to active state is less than 0.2 second.
Notes:
For distances below 1.3m (detection with relative speed only) or below 0.3m (no detection) the
space covered in general by radar systems is very small so this system might not be a suitable
solution.
The Reverse Smart system is not affected if multiple systems are operating in the same area
or on the same vehicle, even if they are installed in close proximity with overlapping detection
ranges.
Tip: The Radar detection is generally better when there is relative speed between the sensor
and the objects.

3. Factors Influencing the Detection of Objects
The Reverse Smart Radar shares in principle the advantages and limitations of all radar-based
systems when compared to other sensing technologies. In general, it can reliably detect most
objects in most environmental conditions such as dirt, dust, rain, snow, sun, fog, darkness,
acoustic noise, mechanical vibration, electromagnetic noise or similar.
However, there are some occasions when an object could stay undetected. Radar works on the
principle of line of sight and relies on some of the electromagnetic energy transmitted by the
sensor being reflected back from the object to the sensor. If an object does not reflect enough
electromagnetic energy back to the sensor it will not be detected.
In the case where there are multiple objects in the detection area at various distances and/or
angles, the sensor detects the closest object, which is the most important one for collision
avoidance.
The object properties, location and direction are key influences in determining if an object is
detected or not. The influencing factors are listed below:
Size: Larger surfaces are detected better than smaller surfaces. If there are small and large
objects in the detection area, the smaller object might only register in Detection Zones closer
to the sensor.
Material: Metal is detected better than non-metal materials, e.g. wood, plastic.
Surface: A smooth and solid surface is detected better than rough, uneven, porous,
fragmented or liquid surfaces, e.g. bushes, brick work, gravel, water.
Shape: A flat object is better detected than a complex shape. Variation in relative location
and direction can influence detection significantly.
Angle: An object facing directly towards the sensor (perpendicular, orientation head on to the
sensor) is detected better than an object that is located towards the edges of the detection
area or at an angle.
Distance: An object closer to the sensor is better detected than one that it is further away.
Relative speed to sensor: Detection is better if there is a relative speed between object and
sensor.
Ground condition: Objects on flat, mineral material ground are better detected than on rough
or metal surfaces.
Weather conditions: Dense dust or very strong rain or snowfall will reduce the detection
capability.

4. Display
The display should be mounted so the vehicle driver has good visibility in all environments and
situations. The display should be fixed in a suitable location in line with current
legislation/regulations.
The base is fixed to the display with a keyway locking method and locked with a machine screw.
The base can be separated from the display by removing the screw and sliding back and down if
the display is used for any flush mounting.
The base has a self-adhesive pad applied for mounting e.g. on the dashboard. Additional drilling
and fixing with screws may be required in some applications.
The neck is adjustable in all directions up to 30° and is secured with a locking nut. Locking nut
should only be tightened by hand and excessive torque should be avoided. The volume is
adjustable from 65 to 90dB measured at 1m distance.

4.1 Initial System Power Up and Test
Once the sensor and display are installed and connected, power should be applied to test correct
system operation. On power up, the display will go through its self-test by sounding the buzzer
and illuminating the Status Light red and all Zone Lights. After about 5 seconds only the Status
Light should show red colour. When the activation input becomes active (e.g. reverse gear is
selected to apply power to the activation input) the status light turns green and the system is in
detection mode. Check the system is operating correctly in an open area with no obstructions.
If the display indicates an error mode (see Section 4 “Display”) check Section 5 “Error States” for
possible resolutions. If any or allof the Zone Lights remain constantlylit, check for any obstruction
in the detection area, which may be detected by the sensor, and remove it. If the systemis working
as described, follow Section 6 “Testing and Maintenance”.

5 Error States
If the display shows an error state (see Section 4 “Display”) check for the following potential issue
below. If the error is resolved the display will return automatically after a few seconds and the
self-test to normal operation.
ERROR
ACTION
Sensor or extension cable not connected.
Check all connectors are plugged together
fully.
No data connection between sensor and
display.
Check for damage on connectors and cable.
No power connection to sensor.
Check for damage on connectors and cable.
CAN communication error with sensor.
Cable is routed or system is installed too
close to an electric noise source in vehicle.
Try to relocate affected part of the system.
Data corruption in sensor.
Consult Reseller for advice.
The Radar cannot self-diagnose potential sensor detection issues caused by the build-up of ice,
dirt, mud, heavy rain or immersion in water, which may impede system performance.
6 Testing and Maintenance
6.1 Vehicle Owner/Driver Instructions
1. The Reverse Smart system is intended as an “Object Detection System”and should not
be relied upon as the primary defence for the safe operation of the vehicle. It is an aid to
contribute in conjunction with other established safety programs and procedures to ensure
a safe operation of the vehicle in relation to surrounding persons and objects.
2. Testing and inspection of the system should be carried out at each major vehicle service
as recommended by the vehicle manufacturer and in accordance with the procedure
outlined in Section 6.2. The owner of the vehicle is responsible for consulting with the
driver to ensure the Reverse Smart System is working as intended.
3. Drivers using this equipment should check the system is in good working order as part of
the daily pre-start inspection of the vehicle.
4. Improved safety depends on the proper function of this product in conformance with these
instructions. It is necessary to read, understand and follow all instructions received with
the Reverse Smart system.
5. The Reverse Smart system for object detection is intended for use on commercial vehicles
and machinery equipment. Correct installation of the system requires knowledge of
vehicle electrical systems and procedures along with proficiency in installation.

6.2 Maintenance and Testing
Procedure:
1. Clean the sensor housing of any accumulation of dirt, mud, snow, ice or any other debris.
2. Visually inspect the Sensor and Display to ensure they are securely attached to the vehicle
and are not damaged.
3. Visually inspect the system’s cables to ensure they are properly secured and not damaged.
4. The location of the test should ensure the area in front of the sensor is clear of obstacles and
is larger than the detection range of 4meters.
If any of the following tests fail, follow the fault finding guidance in Section 4.1 “Initial System
Power Up and Test” of the installation guide.
For the following tests, the driver requires objects to be placed in the detection area or an assistant
(to observe the display indications).
5. Activate the System (ensure the vehicle cannot move) to ensure the Status Light is illuminated
constant green on the display within less than 7 seconds.
6. If the display shows any of the 5 Zone Lights activated, this indicates there are likely to be one
or more objects in the detection area interfering with thetest. Move the vehicle to a clear area
and proceed.
7. Verify each detection zone’s distance: Starting from the outside of the detection area, the
driver should check several points along the centre line of the detection width down to around
0.4m distance from the sensor. The display should show the detection alerts via the lit Zone
Lights, the buzzer pulsing speed and, if the trigger output is used, the connected device or
function. The driver should note down the distance at which each detection zone is activated
and if it is in line with the installed system or the configuration for this vehicle.
8. Close detection behaviour: Verify objects in between 0.3m and 1.3m distance are only
detected if they move relative to sensor. All Zone Lights except for red should be constantly
active. The red colour Zone Light should stay active for systems covering more than 1.1m
distance with the closest detection zone 1.
9. Very close detection awareness: Verify objects less than 0.3m from the sensor are not
detected. All the Zone Lights and buzzer output should switch off after less than 3 seconds
with only the Status Light remaining illuminated constant green.
10. Similar to the previous tests the driver should scan all the edges of the detection area
according to the installed system or configuration for this vehicle. The driver should note down
the detected locations and check if they match with the detection area set when the Reverse
Smart System was installed on this vehicle.
More frequent inspections should be performed in cases where:
The vehicle is operating in a particularly dirty or harsh environment.
The operator has reason to suspect the system is not working or has been damaged.
