6.1 The three standard applications
The following three sensor configurations are the standard applications for TailGUARD™ for Truck & Bus:
The following conditions apply here:
„
15° sensors are installed as the respective exterior sensors. A 15° bend in their housings cause them to point
slightly inwards towards the middle of the vehicle. They monitor the area between the outer edge and the middle
of the vehicle. Using the outer edge of the vehicle as a detection limit is crucial to allow parked vehicles or other
obstacles that are close to the path of travel to be passed unhindered, and to prevent them from being identified as
objects behind the vehicle.
„
A third ultrasonic sensor with a straight housing (0°) is positioned in the middle of the vehicle for better monitoring
of this area.
„
All the ultrasonic sensors have a club-shaped, relatively flat detection field.
„
If a sensor is installed upright, it monitors a horizontal plane at the height of its installation position.
„
If it is installed in a horizontal position, it monitors a vertically oriented plane. This enables it to also detect objects
behind the vehicle that are considerably above or below its installation height.
Further details about the standard installation of the ultrasonic sensors can be found in Section 7.3 of the system
description for TailGUARD™ for Truck & Bus.
