  • Why advanced ITS and

    Safety Systems?

    �Building Ideal VehiclesVehicles

    ○Safer &

    ○ More comfortable

  • Why Advanced ITS & Safety

    Systems? contd.

    � Insert Road Accident Deaths graph from

    Toyota Presentation

  • Why Advanced safety systems? contd.

    � Road accidents continuously rising all

    over the world

    � India accounts for 6% of world deaths

    though it has just 1% of vehicle though it has just 1% of vehicle

    population

    � About 90,000 deaths every year in India

    due to road accidents

  • Safe Vehicles

    Stages of accidents Roles of 3 elements

    � Safe Driving

    � Accident avoidance

    � Collision prediction

  • How do we achieve safety?

    �Extensive use of electronic,

    information and

    communication technologies communication technologies

    �To devise solutions to

    problems which automobiles

    have created- emission and

    safety.

  • � Basic functions of vehicle:

    � Traveling

    � Stopping &

    � Turning

    � ITS (Intelligent Transport System)

    increases vehicle functionality

  • Vehicle Functionality

    � Increasing vehicle functionality means

    �Advancing “Information Service Functions “ that integrates vehicles with telecommunication vehicles with telecommunication systems &

    � “Driving Assist Functions” that use communication and sensing technologies to create intelligent vehicles.

  • Advancement of Information

    Service Functions � Information Service Functions add to

    basic vehicle functions of traveling, stopping and turning the function of � Connecting the vehicles to the Society at

    largelarge

    ○ by use of communication and

    ○ sensing technologies

    � Since traffic safety cannot be ensured by just by controlling individual vehicles BUT interaction of individual vehicles with the entire traffic

  • Information Service Functions

    � Information Service Functions include

    � Car Navigation and

    � Telematics

    � Vehicle Security� Vehicle Security

    � Route Search

    � Operator Service

  • Car Navigation

    � Advanced Car Navigation Systems

    include

    � Road Maps

    � Suggestions on routes based on past � Suggestions on routes based on past statistical data and driving histories

    � Real time information on traffic congestion, accidents, traffic restrictions, parking , etc.

    � Predicting required travel time

  • Telematics

    � Advanced telematics to realize the harmonious coexistence of vehicles and society

    � Route guidance to avoid traffic congestion using advanced technologies to predict road traffic conditions using advanced technologies to predict road traffic conditions

    � On demand entertainment system

    � Emergency call Service tying up with Police and Fire Service

    � Car security to track vehicle thefts

  • Night View

    � System supports driver’s vision at night

    � Near infrared light to display light to display road surface, fallen objects, pedestrians, etc.

    � Display on lower part of the windshield

  • Different views of low beam, main beam and active night vision with infrared light source.

  • Intelligent Parking Assist

    � Ultrasonic sensors used to detect parking space

    � Driver can park the car without any steering operation, just using brakessteering operation, just using brakes

  • Lane keeping Assist Function

    � Lane deviation Alarm

    � Alerts driver with a buzzer and display

    � Applies a small counter steering force to keep it in lanekeep it in lane

  • Lane keeping assist function contd.

    � Lane keeping assist

    � Constantly applies a small counter steering force to help vehicle stay in the middle of the road

  • Pre Crash Safety

    � High performance radar at the front to detect

    vehicles and obstacles

    � Stereo Camera capturing 3 dimensionally

    objects’ positions and distance from the objects’ positions and distance from the

    vehicle

    � Near infrared

  • Driver Monitoring system

    Detection of Facial Width

    Detection of Position Facial Features

    Computation of Facial Center

    Computation of degree of Direction in which Driver’s face is looking based on Detection of Left side & Right side of the face.

    � Camera mounted on steering column & image processing

    computer is used to detect the directions of driver’s face.

    � If the system detects that the driver is not facing forward

    when there is possibility of a collision, it will warn the driver

    more rapidly than if the driver was facing forward.

  • Driver Monitoring system

    � Warns the driver with Buzzer & Warning Light.

    � If driver still does not react, then driver is

    physically warned through application of pre

    crash brakes.

  • Rear Pre Crash Safety
