8.1 DETECTION DEVICES
8.1.1 Introduction
Detection devices are used to assist various vehicle systems in recognising situations,
objects and/or signals.
These devices can use different ways of detecting for example, by using a camera or
a radar sensor.
Camera’s for example, can be used to monitor activity in and around the vehicle during
cornering or while reversing the vehicle.
Radar sensors are used to detect objects and/or movement. An example of such a
radar sensor is the AEBS/ACC sensor.
8.1.2 AEBS/ACC sensor
Introduction
Both Adaptive Cruise Control (ACC) and Advanced Emergency Braking (AEBS) use a
radar sensor to detect objects in front of the vehicle.
NOTE: This AEBS/ACC sensor can detect objects up to 150 metres in front
of the vehicle. The AEBS/ACC sensor measures speed, distance and lateral
position of the object or vehicle in front.
The radio emission of the AEBS/ACC sensor is way below legal limits and
therefore in no way harmful to the driver or any other person.
To determine what 'relevant' objects are, all objects are divided in three categories:
– Moving in the same direction.
– Moving in the opposite direction.
– Stationary.
NOTE: The AEBS/ACC sensor does not react to objects moving away from
the vehicle (overtaking vehicles, for example). This is because the distance
between the vehicles is increasing rather than decreasing.
The AEBS/ACC sensor is located behind a cover plate (A) in the grille of the vehicle.
