- 1. ANURADHA ENGINEERING COLLEGE,CHIKHLI DEPARTMENT OF MECHANICAL ENGINEERING SEMINAR ON Adaptive cruise control (ACC) SEMINAR BY:- ATHARV DIPAK KULKARNI UNDER GUIDANCE OF :- Prof. A.S.PATIL
- 2. CONTENTS:- • Introduction • Why adaptive cruise control • How does it work? • Physical Overview • Components • Cruise Switches • Advantages • Disadvantages • Conclusion • Reference
- 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)
- 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
