Adaptive cruise control (ACC) provides assistance to the driver in the task of longitudinal control of their vehicle during motorway driving within limited acceleration ranges. The system controls the accelerator, engine powertrain and vehicle brakes to maintain a desired time-gap to the vehicle ahead.
Among the recent advancements in car safety technologies, the adaptive cruise control feature is one of the most important and useful. It greatly minimizes the pressure of the driver as it helps to control the speed of the car and maintains a safe distance from other cars to avoid a crash. But still, this adaptive control should not be used in bad weather conditions and in tunnels as they might not work efficiently. So, if you want to know all about the adaptive cruise control system in your car, then give some time to watch the following slide show.

Implementation of Doppler Radar Based Vehicle Speed Detection Systemijtsrd
Nowadays, vehicular accidents have been increasing from day to day. Most of them are the cause of over speeding. This thesis describes the Arduino based vehicle speed detection system using Doppler radar. The primary goal of this system is to design of the vehicle speed detector using Doppler radar which is used to reduce the amount of accidents caused by over speeding. In this system, continuous wave CW Doppler radar which is a special case that only provides a velocity output is used as a sensor and the microcontroller is used to calculate the speed of the vehicle. Moreover, the amplifier is used to amplify the voltage level to drive the microcontroller as the sensor output is in micro volts. It is also included LCD display to indicate the speed level. A Doppler radar that can determine the frequency shift that occurs in electromagnetic waves due to the motion of scatters toward or away from the observer through measurement of the phase change that occurs in electromagnetic waves during a series of pulses. The Doppler frequency is negative for objects receding from the radar. The Doppler frequency is positive for objects approaching the radar. This system can be acceptable in real time applications because it is independent of temperature, humidity, noise airflow, dust, light, etc. The results of design are tested and follow through realization. Each of the implementation is evaluated and these evaluations lead to the conclusion that the design is able to achieve high accuracy of the speed. The major components of the design are Doppler radar HB100 , Arduino Uno, LCD display and LM324. C programming language is developed in this system. The results of this work can improve the performance of automobile safety system.

Under Graduation Final Year Project - Design of Steering wheel with anti-fati...Hariharan L
Road users have long been known to fall asleep whilst driving. Driving long hours can induce fatigue causing lack of concentration and occasionally road accidents. Up to 20% of fatal crashes may be linked to driver fatigue. Our model presented a low-cost and simple distributed force sensor that is particularly suitable for measuring grip force and hand position on a steering wheel. The sensor can be used in automotive active safety systems that aim at detecting driver’s fatigue, which is a major issue to prevent road accidents. The key point of our approach is to design a prototype of sensor units, so that it can serve as platform for integrating different kinds of sensors into the steering wheel.
Today, a typical automobile on the road has computer controlled electronic systems, and the most commonly used embedded systems in a vehicle include Airbags, anti-lock braking system, black box, adaptive cruise control, drive by wire, satellite radio, telematics, emission control, traction control, automatic parking, in-vehicle entertainment systems, night vision, heads up display, back up collision sensors, navigational systems, tyre pressure monitor, climate control, etc
Controlling and Reducing of Speed for Vehicles Automatically By Using Rf Tech...IJERA Editor
For vehicle safety and safety for passengers in vehicle is an important parameter. Most of the vehicles get
accident because no proper safety measures are taken especially at curves and hair pin bends humps and any
obstacles in front of the vehicle. This system can be used for the prevention of such a problem by indicating a
pre indication and also reducing the speed of vehicles by reducing the fuel rate of vehicle. As the action is in
terms of fuel rate so the vehicle automatically goes to control and avoids the accidents. At curves and hair pin
bends the line of sight is not possible for the drivers so the special kind of transmitter which is tuned at a
frequency of 433MHZ are mounted as these transmitters continuously radiate a RF signal for some particular
area. As the vehicle come within this radiation the receiver in the vehicle gets activate. The transmitter used here
is a coded transmitter which is encoded with encoder. The encoder provides a 4 bit binary data which is serially
transmitted to transmitter. The transmitter used here is ASK type (amplitude shift keying) which emits the RF
radiation.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

3. INTRODUCTION
The concept of assisting driver in longitudinal vehicle
control to avoid collisions is adaptive cruise control.
When switched on, this device takes up the task of
accelerating or braking to maintain a constant speed.
An “Adaptive Cruise Control” (ACC) system developed as
the next generation assisted the driver to keep a safe distance
from the vehicle in front.
3
5. availability
ADAPTIVE CRUISE CONTROL is a common term used for
enhanced cruise control system.
Depending on car maker ACC can also be called as Active
Cruise Control (BMW), Distronic (MERCEDES), Dynamic
Cruise Control (TOYOTA).
PORSCHE PANAMERA
VOLKSWAGEN
PASSAT
5
6. Working principle
ACC works by detecting the distance and speed of the
vehicles ahead by using radar system.
The time taken by the transmission and reception is the key
of the distance measurement.
The shift in frequency of the reflected beam by Doppler
Effect is measured to know the speed.
Depending on this speed, the brake and throttle controls are
done to keep the vehicle in a safe position with respect to the
other.
6
7. DOPPLER EFFECT
Doppler Effect is the change in frequency of the waves when
there is a relative motion between the transmitting and
receiving units.
The Doppler Effect can be categorize in two ways:-
DOPPLER EFFECT
HIGHER
PITCH
SOUND
LOWER
PITCH
SOUND
7
8. HIGHER PITCH SOUND
In this case the vehicle is speeding towards the stationary
listener.
The distance between the listener and the car is decreasing.
The listener will hear a higher pitch sound from the car,
which means the frequency of sound, is increased.
8
9. LOWER PITCH SOUND
In this case the vehicle is moving away from the listener.
The distance between and the car is increasing.
The listener will hear a lower pitch sound from the car, which
means the frequency of sound, is decreased.
So that is the Doppler Effect in case of sound waves.
9
10. WORKING OF ACC
The gun transmits the waves at a given frequency toward
an incoming car.
Reflecting waves return to the gun at a different
frequency, depending on how fast the car being tracked is
moving.
A device in the gun compares the transmission frequency
to the received frequency to determine the speed of the
car.
10
11. We can design the chip or ACC having an algorithm such that
it will give output only when the input signals are less than
the corresponding safe distance value.
So only when the between the car and the object in front of it
is less then the same distance value the embedded system will
give output to the breaking and the accelerating units.
Thus the safe distance will be kept always.
11
15. sensors
SENSOR is a converter that measure physical quantity and
converts it into signal which can be read by observer or by
instrument.
SENSOR responds to an input quantity by generating a
functionally related output usually in form of electrical or
optical signal.
In this project three type of SENSOR can be used
SENSORS
RADAR
FUSION
SENSOR
LIDAR
15
16. RADAR
It is an electromagnetic system for detection and location of
vehicle.
It operates by radiating energy into free space and detecting
echo signal reflected from an object.
The reflected energy is not only indicative of the presence but
on comparison with the transmitted signal , other information
of target can be obtained.
The currently used “Pulse Doppler RADAR” uses the
principle of Doppler effect in determining the velocity of
target.
16
18. FUSION SENSOR
This include millimeter wave RADAR linked to a stereo type
camera with a 40 degree view angle.
These two parts work together to track the car from non
moving object.
RADAR’s target is the car rear bumper, the stereo camera is
constantly captures all objects in its field of view.
It was first used by Fujitsu Ltd. and Honda.
18
20. LIDAR
LIDAR stands for “Light Detection and Ranging”.
It measure distance by illuminating laser and analyzing the
reflected light.
By measuring the beat frequency between frequency
modulated continuous light wave and its reflection.
It is of low cost and provide good resolution.
Weather condition restrict its use to 30 to 40 meter range.
The first ACC system used LIDAR sensor.
20
22. MICROCONTROLLER
The AT89S51 is a low-power, high-performance CMOS
8-bit microcontroller with 4K bytes of in-system
programmable Flash memory.
The on-chip Flash allows the program memory to be
reprogrammed in-system or by a conventional nonvolatile memory programmer.
The AT89S51 provides the following standard features:
4K bytes of flash, 128 bytes of RAM, 32 I/O lines,
Watchdog timer, two data pointers, two 16-bit
timer/counters, a five vector two-level interrupt
architecture, a full duplex serial port, on-chip oscillator,
and clock circuitry.
22
25. CONTROLLER ACTION
Depending on present traffic situation two type of controller
are possible: SPEED CONTROL and HEADWAY
CONTROL.
SPEED CONTROL: if there is no vehicle presently in front,
then the speed is controlled about a set point just as in
conventional cruise control.
HEADWAY CONTROL: in order to keep a safe distance
between the vehicle’s the headway control is required.
25
27. ADVANTAGE
The driver is relieved from the task of careful acceleration,
deceleration and braking in congested traffic.
A high responsive traffic system that adjust itself to avoid
accident can be developed.
Since the braking and acceleration are done in systematic
way, the fuel efficiency of vehicle is increased.
27
28. disadvantage
Cost of ACC system is very high.
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 accident if the system is malfunctioning.
28
29. Future scope
The advanced version of ACC is known as COOPERATIVE
ADAPTIVE CRUISE CONTROL (CACC).
In CACC preceding vehicle can communicate actively with
the following vehicle so that their speed can be coordinated
with each other.
29
30. conclusion
It will probably take decades but car accident may eventually
become as rare as plane accidents are now.
Road laws have to be changed, up to an extent since the non
human part of the vehicle controlling will become
predominant.
