car?
INTRODUCTION
• Self driving cars are also known as autonomous car, driverless car, unscrewed vehicle or robotic car.
• Autonomous vehicles sense their surroundings with techniques such as radar, lidar, GPS, cameras, ultrasonic sensors, laser sensors and computer vision.
HISTORIC EVENTS
• First “Auto-piloting” of an airplane was occurred in 1914.• Ships have been using “Self-steering gear” from 1950s.

What Technologie
sare
used?
Technologies
• Anti-lock brakes(ABS) • Electronic stability control (ESC)• Lane Departure Warning System • Cruise control• Self Parking• RADAR & LIDAR• GPS & Night Vision• Ultrasonic Sensors• Cameras
Components
Wheel-speed sensors Steering-angle sensors Rotational-speed sensor
Anti-lock brakes System (ABS)• An ABS generally offers improved vehicle control and
decreases stopping distances on dry and slippery surfaces for many drivers.
Automatic 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)
• 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
Electronic Stability Control
Adaptive Highbeam
• Automatically and continuously adapts the headlamp range to the distance of vehicles ahead or which are oncoming.
• New generation Mercedes-Benz e-class in spring 2009.
Automotive Night Vision
• Increases a vehicle driver's perception and seeing distance in darkness or poor weather beyond the reach of the vehicle's headlights.
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.
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
Autonomous 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
Backup 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.
Self-parking Cars
• System uses sensors all around the car to guide it into a parallel parking space
• 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.

Advantages
• POLICE: Reduction in the need for traffic police and vehicle insurance.
• SIGNS: Reduction of physical road signage.• CHILDREN & TEENAGERS : Smoother ride.• Reduction in car theft, due to the vehicle's self-awareness.• DISABLED: Enjoy improved mobility with on-call, door-to-door
service in specialized vehicles.• ELDERLY: No longer dependent on driving, aging will have
little to no effect on transportation and independence.• ADULTS: Safely use phones, laptops and tablets. Some will get
jump-start on the work, others will socialize or enjoy a video.• ACCIDENTS: No any accidents, car crashes.
Disadvantages
• Loss of driving-related jobs.• Loss of privacy.• Competition for the radio spectrum desired for the car's
communication.• Hackers can change the rout which is plotted in the system.• Self-driving cars could potentially be loaded with explosives
and used as bombs.• Drivers being inexperienced if situations arose requiring
manual driving.• Software reliability & Liability for damage.
The most effective gain of this system will be control on traffic congestions and avoiding accidents.
So the time is not far ‘2020’ when we are going to have our self controlled vehicles and we say “THE FUTURE OF AUTOMOBILES IS HERE”.
