TailGUARD™ for refuse collection vehicles
4.2 Why use TailGUARD™ and not a camera system?
At first glance, a camera that provides the driver of a refuse collection vehicle with an optical image of the area behind
the vehicle would appear to be superior to the ultrasonic-based detection principle used by TailGUARD™.
On closer consideration, however, TailGUARD™ offers decisive benefits, particularly where refuse collection vehicles
are concerned:
„
A camera system requires good light conditions. Adequate lighting is only available during daylight hours, however.
TailGUARD™, on the other hand, always functions equally well whatever the conditions: in daylight, at dawn and
dusk, and even in the dark.
„
With a camera system, while reversing the driver must always keep an eye on both the monitor with the detailed
camera image and the rear-view mirror. This divided attention creates additional stress, and can lead to mistakes
in recognising the situation behind the vehicle. With TailGUARD™, as well as a simple optical signal, the driver is
alerted by additional acoustic warning signals. This enables the driver to visually focus on the rear-view mirror.
„
With a camera system, the driver must himself identify any relevant objects in the camera image. The
TailGUARD™ system automatically recognises both moving and stationary objects.
„
TailGUARD™ also detects and measures the distance to objects in the immediate vicinity of the rear of the vehicle,
and indicates the distances between them, which is something that camera-based systems are not capable of.
„
With a camera system, the driver has to actively decide when to brake and then perform the action. TailGUARD™
on the other hand, can autonomously brake the vehicle when it approaches an object.
„
While the cameras optics need to be regularly cleaned, TailGUARD™ does not require any maintenance.
4.3 Retrofitting TailGUARD™: Requirements for the refuse
collection vehicle
Here are the most essential requirements that have to be fulfilled by the vehicle:
„
Suitable locations for installing the ultrasonic sensors:
• It can be a problem with refuse collection vehicles to find suitable installation locations for the ultrasonic sensors
depending on the installed lifting and tipping system.
• Generally, however, at least two sensors can be successfully installed and configured in such a way as to
provide satisfactory monitoring of the area behind the vehicle.
• In extreme cases, however, special rear-mounted superstructures may mean that it is not possible to use
TailGUARD™ for monitoring the area behind the vehicle. In case of doubt, it is therefore advisable to check
the installation possibilities by conducting tests beforehand to pinpoint suitable positions for the sensors (see
Chapter 7).
„
Supply voltage:
• All vehicles with a 24 V supply voltage can be fitted with the system.
• Vehicles with a 12 V on-board electric system can only be fitted with the system if a permanent supply voltage of
more than 11.5 V is assured.
