This document presents information on driverless cars. It discusses how driverless cars will use sensors to detect objects and traffic lights to slow or stop, reducing accidents. Technologies that enable fully autonomous vehicles are described, including ABS, ESC, cruise control, lane departure warning, self-parking. Automated guided vehicle systems are controlled by computers and GPS to determine location and manage traffic flow. While driverless cars could increase road safety, they may also introduce security risks if hackers are able to access vehicle controls remotely.

2. ABSTRACT
 The object of this project is to drive the car with help of
PC. “The car, using a wide variety of sensors will be easily
able to detect pedestrians, objects which will allow the car
to slow or stop suddenly. As a computer is far more precise
and subject to fewer errors than a human, accident rates
may reduce when these vehicles become available to
consumers. This driverless technology would lead to fewer
traffic jams and safer roads.”

Introduction
What is a driverless car ?
How will car detect the traffic light ?
Technologies making a system fully autonomous
Control of vehicle
Automated guided vehicle system

4. INTRODUCTION
Driver error is the most common cause of traffic
accidents.
India contributes 6%of the world’s road accident
deaths.
Cell phones in car, entertainment system, more traffic
and more complicated road systems making it more
frequent.
By this improving technology our car will do the
concentrating for us.

5. What is a driver less car?
 It is a vehicle that can drive itself from one point
another without assistance from a driver, in other
words, with an autopilot system

6. How will the car detect the traffic
lights ?
A sensor “actinometer” is user to detect the intensity
of radiation.
Light of different colors will radiate different to
different intensity of radiation.
 which will be detected by sensor,
If the detected intensity is of red color or yellow color
then the controller will send a command to stop the
vehicle.
The command will be followed by robot(to convert
the computer command into mechanical input)

7. Technologies making a system fully
autonomous
Anti-lock Brakes(ABS)
Electronic stability control(ESC)
 Cruise Control
Lane Departure Warning System
 Self Parking
 Automated Guided Vehicle System

8. ANTI-LOCK BREAKING SYSTEM
An ABS generally offers improved vehicle control and decreases
stopping distances on dry and slippery surfaces for many drivers.

9. SPEED SENSOR
VALVES
PUMP
CONTROLLER

10. A computerized technology improves vehicle’s stability by
detecting and minimizing skids.
 utomatically applies the brakes.
Help to minimize a loss of control.
ESC compares the driver’s intended direction to the
vehicles actual direction
Components:
Wheel-speed sensors
Steering –angle sensors
Rotational –speed sensors

11. CRUISE CONTROL
 Cruise control keeps the car at a constant speed by
taking over the throttle of the car,it also maintain
a set distance between it and the car in front of it.

12. Lane departure warning system
 A mechanism designed to warn a driver when the
vehicle begins to move out of its lane.
 Designed to minimize accidents by addressing the
main causes of collisions, driving error, distraction and
drowsiness.

13. Self-parking
System uses sensors all around the car to guide it into a
parallel parking space
Lexus LS 460l with advance parking guidance system
The driver has to find a parking space Position the car
next to it, and use the in-cabin navigation screen to tell the
car where it should go.
The parking space needs to be 6 feet (1.8 meters)longer
then car

14. Backup camera & parking sensors
Special type of video camera attached to the rear of a
vehicle to a vehicle to aid in backing up.
Parking sensors are proximity detectors which can alert
driver to unseen obstacles during parking.

15. As automotive technology matures, more and more
functions of the underlying engine, gearbox etc are no
longer directly controlled by the driver by mechanical
means.
It controlled via a computer, which receives instructions
from the driver as inputs and delivers the desired effect by
means of electronic throttle control, so that the technology o
computer handle the vehicle.

16. Automated guided vehicle systems
Uses FROG (Free Ranging On Grid) Technology.
FROG vehicles are equipped with a computer that
contains a map of the area.

17. Advantages:
 Managing traffic flow to increase road capacity
 To avoid accidents
 The current location of vehicle can be determine by using G.P.S
Disadvantages:
 If the vehicle is using internet which have less security then
from the hackers point of view some cases the vehicle con be
switched off on the road (rear cases)

18. CONCLUSION
The driver less car’s technologies improves vehicle’s
stability helps to minimize lose of control.
Driver less cars are designed to minimize accidents by
addressing the main causes of collisions, driving error,
distraction and drowsiness
