D5 fails AEB test

This was posted on another LR forum by a Swedish owner and confirmed something many owners of Disco Sports have been expressing concern about

Google translate will change to English but it basically found over 15kmh AEB was ineffective Shocked

Land Rover's new Discovery was equipped with car bombs.
But failed to brake at all.
After the car of the year jury's big car bomb test, Land Rover has launched an internal survey of its cars.

Land Rover Discovery had tougher. Despite the fact that the car is equipped with a car boot system, the test car failed to brake the balloon car at 15 km / h or higher. The test group made another test that went even worse.


Yep, got it.

I guess we all know that "AEB" is Autonomous Emergency Braking which relies on forward facing cameras.

For what it's worth Land Rover say:-

Quote:
The AEB system will not operate if:

Dynamic Stability Control (DSC) is switched off.

The vehicle's speed is below 3 mph (5 km/h) or above 50 mph (80 km/h).

The detected object is not identified as a vehicle.

The AEB system may not operate if:

The vehicle is negotiating a bend.

The forward-facing cameras are dirty or obstructed.

Visibility is impaired due to severe weather conditions (for example, heavy rain, fog, snow, etc.).


I'm not sure which vehicles have AEB, certainly the Velar, Discovery 5 & possibly the Discovery Sport.

if I've got this right, it will detect a pedestrian when you're doing 51mph but will happily run them over ?

The DS was the first to receive it along with the pedestrian airbag which hasn’t made it onto other models.

As said there has been a lot of doubts about the AEB on the DS amongst owners.

Quote:
The Autonomous Emergency Braking (AEB) system uses forward-facing cameras to detect real vehicles, plus other certified Euro NCAP target objects. It is not designed to detect any other objects, including non-industry approved targets.


Quote:
In order for the AEB system to operate, it must be able to detect a clear image of the object and be able to determine its movement. If either of these does not occur, the AEB system may not operate.


From the above it appears that AEB works for real vehicles & NCAP targets which have to be moving.

It appears that it won't recognise a stationery pedestrian, and it is not apparent that it will recognise a moving pedestrian.

I am afraid that now all vehicles are designed to meet "statutory" legislation rather than the real world.

I'm not talking about LR now.... I'm just saying that then many manufacturers use misleading advertising, we continually see advertisements where they use pedestrians to talk about these novel security systems

The tests do use a pedestrian simulation which is supposed to have radar and IR similarities to a real pedestrian.



To be honest, I think even if the system reduces the impact t speed appreciably it is a good thing. Yes, a full stop before impact would be ideal but better to be hit at 10mph than 30mph, for example.
