Anybody know if there is a minimum speed that activates the auto breaking system on Volvo fh or is it operational all the time when moving?

I found this:
‘‘The system shall be active at least within the vehicle speed range of 15km/h up to the maximum design speed of the vehicle, and at all vehicle load conditions, unless manually deactivated as per paragraph5.4.below.’’
It’s from unece.org/fileadmin/DAM/tra … 131r1e.pdf
‘‘Uniform provisions concerning the approval of motor vehicles with regard to the Advanced Emergency Braking Systems (AEBS)’’ by the UN.
So my guess would be 15km/h

Thanks for the link.
Anyone know anything specificly about volvo fh? I can’t find anything on their website about the activation speed.

Sigh, I don’t understand why you really want to know but here’s a link to a 660 page handbook/manual, if you dare:

Why not call your local Volvo dealer or service and ask them (I doubt they will know)
Having just done a little test, +15mph it’s active, below 15mph inactive…

I would hope that if I contacted a main dealer they would know! Why wouldn’t they?
The reason I want to know is somebody I know just stoved one in the back of another vehicle at low speed and there is whispers from higher up that the driver had it de-activated (something the driver denies) but as it was a low speed smash it made me wander about it because I’m sure someone told me about it only working over a certain speed …

Now the above statement changes it,
Do you mean they had turned the Anti-collision braking off, the abs/aebs works all the time, unless lead is out, VEB is + - 15mph, So which system…
odr.chalmers.se/bitstream/20.50 … 257388.pdf , Page 4
Volvo’s AEBS uses a radar and a camera to keep track of the objects ahead of the HGV [10]. A radar system
can measure the distance and velocity to the tracked objects with high accuracy, but is not as accurate when it
comes to determining angles or object type. A camera on the other hand, can determine angles and object
type, but only give a rather rough estimation of the distance. If both the radar and the camera are tracking an
object, and they agree on the values of the longitudinal and lateral position as well as velocity of the object,
their information can be fused. Through the fusion, the advantages of radar and camera can be combined to
acquire a clearer picture of the surroundings and thereby reduce the risk for misinterpretations. Thus, fusion
makes the collected data more precise and trustworthy. Altogether, the sensor can keep track of several objects
where some are radar only objects, some are camera only objects and some are fused objects. The functionality,
advantages and limitations of the radar is further described in Section 2.3.
2.1.2 Limitations of the system
…
There are several ways in which the system can be deactivated. First of all, there is a button that the
driver can simply push to turn it off. If the sensors are misaligned or covered in some way, e.g. by snow, rain or
dirt, and thus have limited functionality, the system is automatically turned off and the driver will be informed
about this. The driver can also perform a so called acceleration pedal kickdown, which is when the driver gives
full gas and then also an extra push to the acceleration pedal. This action deactivates the system for 15 seconds.
However, if there has been a kickdown for more than one minute, the system is reactivated. Moreover, the
system is deactivated if there have been three interventions from AEBS. Reactivation is performed when the
HGV visits a service center.
^^^Now keep in mind this is a ‘‘Master’s thesis in Engineering Mathematics and Computational Science and Applied Physics’’ so it’s only as accurate as the author’s research

Not sure what VEB is? Engine brake?
But I found an official Volvo video yesterday that clearly states that the AEBS only activates above 15kph.
It’s was claimed by management that the driver deactivated the AEBS by the switch on the dash…
Not sure if the legality of turning it off or not? I guess it’s now illegal to turn it off as the system has to be fitted under EU law?
Anyway if he crashed under the activation speed it wouldn’t have stopped the accident.
