- 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

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.
