- ARS 2-X (adaptive cruise control)
- 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:
- Basic function:
- The social aspects of ARS 2-X:
- No risk compensation
- Consumption reduction
- The comfort of the system allows the driver to maintain his attention span over long distances
- The driving style of the ARS 2-X driver becomes more foresighted and mindful of distances
- ARS 2-X vehicles increase the traffic flow
- - Main area of use: Highways and expressways
- - Speed range: 30 ...... 180 km/h
- - Automatic brake: max. 20% of full braking
- - Additional functions: - Speed limiter - Audible information about moving and stationary objects
- (even when ARS 2-X is switched off)
- Information that the ARS 2-X provides for the driver: - Ideal distance - Detects the vehicle in front - Actual distance from the vehicle in front - Ideal speed - Speed of the vehicle in front - Insufficient distance warning
- - Warning when the system is switched off automatically
- 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 incorrec
- Examples:
- - Late reaction to vehicles cutting in front
- - Detection reliability not 100% (see the example of negotiating curves)
- Take this opportunity for yourself and your customers

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
