Adaptive cruise control (ACC) is an automotive system that allows cruise control to adjust a vehicle's speed based on traffic conditions. It uses sensors to detect slower moving vehicles ahead and slow the vehicle down to maintain a safe following distance without driver input. ACC works by slowing or accelerating a vehicle to match the speed of surrounding traffic. It relies on components like an ACC module, engine control module, brake control module and more to function properly. ACC provides benefits like relieving driver stress in traffic, improving safety by avoiding accidents, and increasing fuel efficiency. However, it also has disadvantages like requiring high market penetration to be truly effective and potentially encouraging driver complacency. Future developments could include vehicles that communicate with each other for improved detection

3. Introduction
What is Adaptive Cruise Control?
• Adaptive Cruise Control (ACC) is an automotive feature that
allows a vehicle's cruise control system to adapt the vehicle's
speed to the traffic environment.

4. Why Adaptive Cruise
Control? (ACC)
• Everyday the media brings us the horrible news on road
accidents.
• The death on the street account for more that 17% of total
death around the world.
• Once a report said that the damaged property and other costs
may equal 3 % of the world’s gross domestic product.

5. How does it work?
• If a slower moving vehicle is detected, the ACC system
will slow the vehicle down and control the clearance, or
time gap, between the ACC vehicle and the forward
vehicle
• If the system detects that the forward vehicle is no longer
in the ACC vehicle's path, the ACC system will accelerate
the vehicle back to its set cruise control speed

8. Components
• ACC Module
• Engine Control Module
• Brake Control Module
• Instrument Cluster
• CAN (Controller Area Network)

9. Cruise Switches

10. Advantages
• The driver is relieved from the task of careful acceleration,
deceleration and braking in congested traffics.
• A highly responsive traffic system that adjusts itself to avoid
accidents can be developed.
• Since the braking and acceleration are done in a systematic
way, the fuel efficiency of the vehicle is increased.

11. Disadvantages
• A high market penetration is required if a society of intelligent
vehicles is to be formed.
• Encourages the driver to become careless. It can lead to severe
accidents if the system is malfunctioning.
• The ACC systems yet evolved enable vehicles to co-operate
with each other vehicles and hence do not respond directly to
traffic signals.

12. Future Scope
• Newer models have intuitive brake control. Newer systems have also
eschewed the use of laser and radar for advanced GPS systems, giving
them much more control and much more accurate information.
• The next technological development in adaptive cruise control will be
systems that can send and receive messages to other cars, enabling a
much more reliable system of detection.
• There are also pushes for better intuitive speed control mechanisms.

13. Conclusion
• An independent evaluation reported that ACC systems
would prevent 6% to 15% of all rear-end crashes
World Wide each year
