INTRODUCTION
This seminar is based upon HANDFREE DRIVING. It was named the Automotive Collision Avoidance Systems (ACAS) field operation program to build the tomorrow’s car. It uses  latest  technologies  of radar sensing to prevent collision. Video imaging to track its path, and uses DGPS for locating the position  of the vehicle on the road. It completely utilized the latest  technologies  in  Robotics as obstacle sensing, tracking and  identification.

3. DEFINITION
All of us would like to drive our car with a mobile held in one hand, talking to the other person. But we should be careful; we don't know when the car just before us apply the break and everything are gone. A serious problem encountered in most of the cities, National Highways, where any mistake means no 'turning back'! There comes the tomorrows technology; Hand free driven car. Initializing the modern technological approach in Robotics.

4. What is the need for safety precaution????
All around the world almost 45% of the accidents occur by mistakes of the driver. In some cases the driver is engaged in some other affair than driving. In USA the highways are so crowded that in some situations mistake on the part of one person on the road can lead to serious accidents. Most of these accidents are fatal., some even risk their life by their careless driving. This was the main reason behind this idea work put forward by the Delphi-Delco electronic systems and General Motors Corporation. It was called the Automotive Collision Avoidance Systems (ACAS) field operation program

ACAS
It is the Automotive Collision Avoidance System.
Aimed at integration of the latest technology Forward Collision Warning (FCW) and Adaptive Cruise Control (ACC).
Now the Field Operation tests are being carried out.

FCW
It is the Forward Collision Warning
system.
It uses the long range forward-looking
radar sensor.
It incorporates the single active
forward-looking radar sensor augmented
with yaw rate sensor

FORWARD LOOKING RADAR
The radar uses 76GHz signals.
Identifies the track up to 150meters for
any stationary or moving obstacle.
Reduce the need for drivers to manually adjust speed
with Headway Alert automatically manages
vehicle speed to maintain a time gap (following distance) set by the driver.

ACC
The Adaptive Cruise Control (ACC)
Detects and tracks motor vehicles in its forward path,
Maintains the selected cruise speed when there is no vehicle limiting its forward motion,
Maintains a selected headway between the host vehicle and a lead vehicle, which is traveling slower than the selected cruise speed and thus limiting the forward motion of the host vehicle.

FORWARD VISION SENSOR
The forward vision sensor to provide lane tracking to help distinguish in-path from out-of-path targets
a video camera mounted behind the windshield of the vehicle to estimate road shape, lane width, vehicle heading and lateral position in the lane.
Uses a 233MHz Pentium MMX processor.
Adequate road shape estimate of at least 75 meters ahead of the vehicle

ROAD MAP DATABASE & GPS
Road map database fed to the CPU of the vehicle.
The information from the DGPS + road map database fused in DATAFUSION SYSTEM.
It provide data of path and position of the vehicle.

17. BRAKE AND THROTTLE CONTROL
Data from ACC + radar sensor fused and fed to processor.
Processor data controls actuators.
For speed less than cruise speed, the driver is informed.

BENEFITS
Conveniently manages vehicle speed and headway gap.
Cruise control more useable in most traffic
conditions resulting in a more relaxed driving experience.
Operates under wide range of environmental conditions (dirt, ice, day, night, rain, or fog).
Low false alarm rate.

24. CONCLUSION
Robotics is the part of Electronics Engineering , which exploits each aspect of Electronics and Mechanical Engineering. The development of robotics have led to the ACAS program. On the completion of this program vehicles will change the phase of driving; a “hand-free” driving.
