1. ARS 2-X function
ARS 2-X is a completely new type of cruise control system that
supports the driver while driving. However, ARS 2-X does not
relieve the driver of their responsibility or reduce the pleasure of
driving.
ARS 2-X is an extension of the normal cruise control function that can
not only keep the speed constant, but will automatically adjusts the
speed to the flow of the traffic in front.
The system may be operated like a normal cruise control:
Whenever you press the accelerator, the car accelerates
Whenever you brake, the system will switch off
The driver is relieved of routine work (such as, taking note of the
maximum speed limit, reading the speedometer, estimating the distance
from the vehicle in front, and constantly regulating these parameters with
the accelerator and brake pedals) during NORMAL DRIVING.
The driver has time to observe the traffic in front, to decide on a driving
strategy, and to react in sufficient time to critical situations. This is the
reason why driving with ARS 2-X is less tiring and is safer and far more
enjoyable.
Basic function:
•
As long as the road is free in front of the vehicle, the ARS 2-X
keeps the set speed constant.
•
If the vehicle approaches a slower-moving vehicle in front, it adapts
the speed to the vehicle ahead and then maintains the selected
time-distance (in seconds) from this vehicle.
•
When the road becomes clear again, the vehicle again accelerates
back to the set speed.

•
The set speed can be selected in 5 mph (10 km/h) increments
(irrespective of the speed at which the vehicle is currently traveling)
•
The ranging cruise control includes the possibility of limited brake
actuation. This allows you to adapt the speed comfortably and
relatively quickly by use of the finger controls. The limited braking
will also prevent the vehicle from traveling unintentionally faster on
roads with a gradient.
2. Benefits to the customer
•
•
•
•
•
Relaxed driving
Less fatigue
Driving with better anticipation
Noticeable on every journey
Active safety improvements thanks to driving more attentively and
with more awareness of distances
• The many benefits of the ARS 2-X can also be seen in the comments
from the assessments of drivers (see below)
• The best arguments, favoring ARS 2-X can be experienced by
DRIVING with the system
3. How drivers assess the ARS 2-X based on their own
EXPERIENCE

I’m enthusiastic about it – I want this function!
Very pleasant
Helpful and stress-reducing
I needed half an hour to get used to this completely new driving
experience.
Before I drove with the ARS 2-X, I thought I wouldn’t need
something like that.
I’ll never again drive too slowly. Whenever the traffic situation
permits, I’ll drive at exactly the speed I want to drive at.

I’ll never again drive too fast. As soon as I see a speed limit, I’ll
adjust my desired speed and I’m sure that I won’t exceed the limit
through lack of attention or driving downhill.
Never again will I maintain an insufficient distance from the car in
front, so I’ll avoid getting penalty points on my driver’s license.
It doesn’t get on my nerves so much when I have to drive behind a
slower vehicle.
My wife feels much more comfortable as a passenger since I’ve
been driving with the ARS 2-X.
It’s a real contribution towards active traffic safety – I’m more
relaxed and more attentive than before.
I always notice the benefits of this system when I’m driving.
ARS 2-X is a must for everyone who drives outside of towns

5. Limitations of the system
The ARS 2-X is an innovative driver assistance system that can support
but not replace the driver.
The driver’s sensory organs and data processing capacity cannot be
reproduced by today’s technology, which is the reason a system like
ARS 2-X can only support and cannot replace the driver.
- No reaction to stationary obstacles
- There may be incorrect reactions, but these can be recognized in time
by the driver and remedied.
Examples:
- Late reaction to vehicles cutting in front
- Detection reliability not 100% (see the example of negotiating curves)

6. Tips for optimum use of the ARS 2-X
• Always set the set speed to the speed that you would drive at if there
were no vehicle in front of you.
• When a vehicle cuts in front of you, drive directly up to the vehicle.
• When approaching exits, reduce the set speed to allow the ARS 2-X
to slowly decelerate the vehicle.
• If you approach a vehicle at very high speed, reduce the set speed in
good time.
• If the ARS 2-X accelerates the vehicle too slowly, take the opportunity
to briefly harmonize the system with the accelerator pedal.
• If you must brake yourself, immediately after braking activate the
Resume function in order to reactivate the system to the previous set
speed.

Appendix:
The constant tasks of the drivers and the influence of ACC:
•
Anticipating the traffic and road situation
•
Speed selection
- Noting the maximum permissible speed
- Adapting the speed to the driving and traffic situation
- Performing the control task
• Selecting and calculating the ideal distance
- Estimating the distance
- Regulating the distance, taking into account the maximum speed
•
Deciding on the ideal driving trajectory
- Performing the ideal / actual adaptation,
or regulation (steering)
The tasks written in gray are largely taken care of by the ARS 2-X.
