This presentation basically talks about the anti collision technology which is particularly implemented in cars in which cars are developed with anti collision technology which reduces the collision between them.
ANTI COLLISION DEVICES
THE CONCEPT OF CRASHLESS CARS
Anti Collision Device(ACD)
A train collision preventing system
Invented by Konkan Railways, over a period
of 90 days.
Meets the challenges of Railway Transport
India the only country to possess such a
Based on radio communication,
Microprocessors and GPS Technology.
Enables trains to automatically assess each
other’s course and prevent an imminent
Also prevents side and rear end collisions.
Intel 80386 Microprocessor , integrated
radio modem works on real time operating
The ACD Network
Works on engine battery system, and also powered by solar
technology, if required.
A Network of ‘on-board’ (Locomotive and Guard) and
‘track-side’ (Station, Level Crossing, Loco shed, Repeater
and Sensor-based) ACDs that work on the principle of
‘Distributed Control Systems’.
ACDs interact en-route with each other through radio
communication within a radial range of 3 Kms.
On-board computers use input from GPS system for
determination of Train location, Speed, Course of travel and
Mobile and stationary components of ACD
exchange information and take decisions
based on train working rules.
If 2 ACDs are deemed to be at a risk of
ACD system activates automatic braking
Detection & Prevention of Head-on, Rear-end
and Side Collisions – A UNIQUE feature even
when a train is not protected by a signal, as in a
‘Train Approach’ Warning for road users at
Level Crossings both manned and unmanned.
Station Approach Warning to Drivers - Can
result in saving of manpower.
Manual SOS functionality available for Drivers,
Guards and Station Masters.
Auto Brake Test – Generating braking
Efficacy Of ACDAnalyzed For Indian
82 % train collisions ‘preventable’ by this
system, during the analysis period of five
Rest cases ‘non preventable’, based on
Phenomenal increase in the volume of
trains running on the same track.
Next generation automotive safety
technology to make driving safer and faster.
Leading car makers already offering
advanced technologies in top-end cars.
Heavy investment- key obstruction in
making it popular.
Also a possibility of robotic vehiclesdriverless cars.
Anti-lock Braking Systems(ABS)- improve
steer ability and hasten deceleration.
Traction Control System(TCS)- improving
overall vehicle control.
Enhanced Stability Control(ESC)- prevention
of de-alignment.- results in 30% less single
Latest technology uses the above in
addition to some newer techniques.
Use of sensors, cameras , radars to monitor
incoming and surrounding traffic.
Networking between the
cars’ computers to take
Collision Warnings- cruise
A long-distance, 77-gigahertz, microwave radar
sensor monitors out to 400 to 650 feet ahead.
Shorter-range, 24-gigahertz, radar unit scans
several tens of meters up front.
Wide-angle video cameras recognize objects
about 130 to 165 feet away
Warning system in case of danger- prepares for
Automatic Braking &
Lane Departure Systems
System automatically hits the brakes or steers
cars back into their lanes to avoid accidents
Use of laser beams to look for reflections from
objects upto25 feet away.
In case of driver’s inaction, applies brakes
Warning the drivers in case of drifting from
lane- appropriate braking to re-align the car.
Blind Spot Cameras- cameras on the
outside of the vehicles that can identify
objects normally hidden from view.
Use side-mounted ultrasonic or radar
