SELF DRIVIRING CAR
ContentsContents
• Introduction
• What is a driverless car ?
• How will the car detect the traffic lights ?
• Technologies making a system fully autonomous
• Control of vehicle
• Automated Guided Vehicle Systems
INTRODUCTIONINTRODUCTION
• 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 systems, more traffic
and more complicated road systems making it more
frequent
What is a driverless car ?What is a driverless car ?
• It is a vehicle that can drive itself from one point to
another without assistance from a driver; in other words,
with an autopilot system
How will the car detect the traffic lights ?How will the car detect the traffic lights ?
• A sensor “actinometer” is used to detect the
intensity of radiation
• Light of different colors will radiate different -2-
intensity of radiation
• Which will be detected by the sensor
• If the detected intensity is of red color or yellow
color then controller will send a command to stop
the vehicle .
• The command will be followed by robot(to convert
the computer command into mechanical input)

• Automated Guided Vehicle
Systems
Anti-lock brakes System (ABS)Anti-lock brakes System (ABS)
• An ABS generally offers improved vehicle control and
decreases stopping distances on dry and slippery surfaces
for many drivers.
Parts of (ABS)Parts of (ABS)
• Speed sensors
• Valves
• Pump
• Controller
Automatic BrakingAutomatic Braking
• Senses an imminent
distance with another
vehicle or a velocity
related danger.
• Responds by either
precharging the brakes or
by applying the brakes to
slow the vehicle without
any driver input.
• Detects by radar, video,
infrared, ultrasonic, GPS
sensors.
• Introduced by Toyota.
Electronic Stability Control (ESC)Electronic Stability Control (ESC)
• A computerized technology
improves vehicle's stability by
detecting and minimizing skids.
• Automatically applies the
brakes.
• Helps to minimize a loss of
control.
• ESC compares the driver's
intended direction to the
vehicle's actual direction
ComponentsComponents
 Wheel-speed sensors
 Steering-angle sensors
 Rotational-speed sensor
Electronic Stability ControlElectronic Stability Control
Cruise controlCruise 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
Autonomous Cruise ControlAutonomous Cruise Control
• Uses either a radar setup
allowing the vehicle to
slow when approaching
another vehicle and
accelerate again to the
preset speed when traffic
allows
Automotive Night VisionAutomotive Night Vision
• Increases a vehicle driver's perception and seeing distance
in darkness or poor weather beyond the reach of the
vehicle's headlights.
Cars currently using A.N.V.Cars currently using A.N.V.
Active systems use an infrared light source
• 2002-2007 Lexus LX 470
• 2009 Lexus LS
• 2006 Mercedes CL-class
• 2009 Mercedes E-class
• 2005 Mercedes S-class
• 2009 Mercedes S-class
• 2008 Toyota Crown Hybrid
• 2002 Toyota Land cruiser Cignus
Lane Departure Warning SystemLane 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.
Adaptive HighbeamAdaptive Highbeam
• Automatically and continuously
adapts the headlamp range to the
distance of vehicles ahead or which
are oncoming.
• The range of the beam can vary
between 65 and 300 meters,
depending on traffic conditions.
Self-parking CarsSelf-parking Cars
• System uses sensors all around the car to guide it into a
parallel parking space
• Lexus LS 460 L 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
than the car
Self driving car
Backup Camera & Parking SensorsBackup Camera & Parking Sensors
• Special type of video camera attached to the rear of a
vehicle to aid in backing up.
• Parking sensors are proximity detectors which can alert
the driver to unseen obstacles during parking.
Control of vehicleControl of vehicle
• 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 is controlled via a computer, which receives instructions
from the driver as inputs and delivers the desired effect by
means of electronic throttle control.
• Therefore, the technology for a computer to control all
aspects of a vehicle is well understood.
AdvantagesAdvantages
• Managing traffic flow to increase road capacity.
• Relieving vehicle occupants from driving allowing them to
concentrate on other tasks or to rest during their journeys.
• To avoid accidents .
• Increasing roadway capacity by reducing the distances
between cars.
• The current location of vehicle can be determine using
global positioning system (G.P.S) .
• Fuel efficient driving, saves 10-15% of fuel
DisadvantagesDisadvantages
• If the vehicle is using internet which is have less security
then From the hackers point of view in some cases the
vehicle can be switched off on the road in rare cases
• Hackers can change the rout which is plotted in the system
in rare cases
• In case of failure of main sensor and backup sensors the
vehicle can create a chance of accident in rare cases
conclusionconclusion
• The driver less car’s technologies improves vehicle's
stability helps to minimize loss of control.
• Driver less cars are designed to minimize accidents by
addressing the main causes of collisions: driving error,
distraction and drowsiness.

Self-parking CarsSelf-parking Cars • System uses sensors all around the car to guide it into a parallel parking space • Lexus LS 460 L 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 than the car
  • 21. Backup Camera & Parking SensorsBackup Camera & Parking Sensors • Special type of video camera attached to the rear of a vehicle to aid in backing up. • Parking sensors are proximity detectors which can alert the driver to unseen obstacles during parking.
  • 22. Control of vehicleControl of vehicle • 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 is controlled via a computer, which receives instructions from the driver as inputs and delivers the desired effect by means of electronic throttle control. • Therefore, the technology for a computer to control all aspects of a vehicle is well understood.
  • 23. AdvantagesAdvantages • Managing traffic flow to increase road capacity. • Relieving vehicle occupants from driving allowing them to concentrate on other tasks or to rest during their journeys. • To avoid accidents . • Increasing roadway capacity by reducing the distances between cars. • The current location of vehicle can be determine using global positioning system (G.P.S) . • Fuel efficient driving, saves 10-15% of fuel
  • 24. DisadvantagesDisadvantages • If the vehicle is using internet which is have less security then From the hackers point of view in some cases the vehicle can be switched off on the road in rare cases • Hackers can change the rout which is plotted in the system in rare cases • In case of failure of main sensor and backup sensors the vehicle can create a chance of accident in rare cases
  • 25. conclusionconclusion • The driver less car’s technologies improves vehicle's stability helps to minimize loss of control. • Driver less cars are designed to minimize accidents by addressing the main causes of collisions: driving error, distraction and drowsiness.
