Slide 1: 2/2/2009 “ Hand free Driven Car ” “ TECHNOLOGY :- The spice of Life ” By -: Navneet Maurya Slide 2: 2/2/2009 Introduction Definition - : Hands free is an adjective describing equipment that can be used without the use of hands. All of us like to drive our car with a mobile in one hand, talking to the other person. But we shouldn’t.
Because here any mistake means,
‘ No Turning Back ’! Slide 3: 2/2/2009 So, There comes the tomorrow’s technology. Hand free driven car. Slide 4: 2/2/2009 History The history of autonomous vehicles starts in 1977 in Japan. It achieved speeds of up to 30 km/h, by tracking white street markers.
In the 1980s a vision-guided Mercedes-Benz robot van, designed by Ernst Dickmanns at the University der Bundeswehr, Germany, achieved 100 km/h.
In 1995, Dickmanns´ re-engineered autonomous S-Class Mercedes-Benz took a 1600 km trip from Munich to Copenhagen and back, using computer vision and transputers to react in real time. The robot achieved speeds exceeding 175 km/h, with 95% autonomous driving. Again it drove in traffic, executing manoeuvres to pass other cars.
In 1995, the Carnegie Mellon University Navlab project achieved 98.2% autonomous driving on a 5000 km "No hands across America" trip. This car, however, was semi-autonomous by nature: it used neural networks to control the steering wheel, but throttle and brakes were human-controlled. Slide 5: 2/2/2009 Existing Technologies In order to drive a car, a system would need to: Understand its immediate environment (Sensors)
Know where it is and where it wants to go (Navigation)
Find its way in the traffic (Motion planning)
Control of vehicle (Actuation)
Arguably, 2 1/2 of these problems are already solved: Navigation and Actuation completely, and Sensors partially, but improving fast. The main unsolved part is the motion planning. Slide 6: 2/2/2009 Sensors Sensors employed in driverless cars vary from the minimalist ARGO project's monochrome stereoscopy to mobileye's inter-modal (video, infra-red, laser, radar) approach.
Self-Steering GPS System for Cars Slide 7: 2/2/2009 Navigation The ability to plot a route from where the vehicle is to where the user wants to be has been available for several years Slide 8: 2/2/2009 Motion Planning This system helps to finds its way in traffic Slide 9: 2/2/2009 Control of vehicle Automatic Stability Control (ASC): It control the vehicle automatic. Slide 10: 2/2/2009 Work done in simulation While developing control systems for real cars is very costly in terms of both time and money, much work can be done in simulations of various complexity. Slide 11: 2/2/2009 Recent Projects Fully autonomous vehicles
Assistance systems There are three approaches for the Recent Projects : Slide 12: 2/2/2009 Fully Autonomous Vehicles They require a car to drive itself to pre-set target using un-modified infrastructure.
Vehicles for paved roads:
The 800 million Euro EUREKA Prometheus Project on autonomous vehicles (1987-1995).
The third competition of the DARPA Grand Challenge held in November 2007.
Free-ranging military vehicles:
There are three cluster activity relating to free-ranging. Some of these projects are military-oriented.
US military DARPA Grand Challenge
European Land-Robot Trial (ELROB)
The Israeli Military-Industrial Complex Slide 13: 2/2/2009 Pre-built Infrastructure The following projects were conceived as practical attempts to use available technology
Dual mode transit - monorail
Automated highway systems
Free-ranging on grid
Electric vehicles locate themselves using readings & recalibrating themselves occasionally using a "maze" of magnets embedded in the environment Slide 14: 2/2/2009 Dual mode transit - monorail Centrally managed, fully computerized transport system Slide 15: 2/2/2009 Automated Highway Systems An effort to construct special lanes on existing highways Slide 16: 2/2/2009 Driver-assistance Driver-assistance mechanisms are of several distinct types,
Systemic Slide 17: 2/2/2009 Warn or inform the driver about events that may have passed unnoticed Sensorial-informative Slide 18: 2/2/2009 Actuation-corrective Anti-lock braking system (ABS)
Traction control (TCS)
Four wheel drive (AWD)
Electronic Stability Control (ESC)
Dynamic steering response (DSR) Slide 19: 2/2/2009 Systemic Automatic parking
Follow another car on a motorway
Nissan's "Distance Control assist"
Death Brake Slide 20: 2/2/2009 In film In 1989 film Batman
In 1994 film Time cop
In 2000 film The 6th Day
In 2004 film I, Robot
In 2004 Tarzan -The wonder car This technology is very known in film industrie. Slide 21: 2/2/2009 Conclusion As we are going searching and searching new technology we becomes a member advance society.
As we found new technology for the “Hand free Driven Car”,
which made our life more easier that finally means: - “Technology- The spice of Life” Slide 22: 2/2/2009 Thank You
