The document discusses real-time vision systems for intelligent vehicles. It describes an Automotive Collision Avoidance System (ACAS) that incorporates forward collision warning (FCW) and adaptive cruise control (ACC) to allow for hands-free driving. The system uses radar, cameras and GPS to detect vehicles and road conditions to control braking and throttle for collision avoidance and maintaining distance between vehicles.

3.  Everyone like to have a mobile held in one
hand talking to others while driving car.
 Serious accidents occurs.
 There comes thought about having a
intelligent vehicles which helps hands free
driving.

4.  Accidents due to careless driving risked many
lifes.
 To avoid this work put forward by delphi-
delco electronic systems & general motor
corporation.
 Also called automative collision avoidance
system.

5. ACAS
 Automotive collision avoidance system.
 Acas program has a highly focused goal of developing a
FCW system that is seamlessly integrated into the
vehicle infrastructure.
 It incorporates the combined ACC & rear end CW
functionality.

6. FCW
 It is the forward collision warning system.
 It included the forwarded looking radar sensing
system.
 This reduces the need for driver to carry out manual
operations.
 Vehicle’s braking and throttle systems.

8.  It is the adaptive cruise control system.
 Approaches are:
 (a) vision based road prediction.
 (b) GPS based road prediction.
 (c) radar based scene tracking.
 (d) yaw rate based road and host state
estimation.

12.  The most important part of the ACC system is
the digitized GPS.
 Global positioning satellite systems (GPS) are
navigation tools which allow users to
determine their location anywhere in the
world at any time of the day.

13. BRAKE CONTROL system
The braking control system includes
ABS,stability enhancement,and traction control
features
The brake system will be respond to ACC
braking commands

14. THROTLE CONTROL SYSTEM
The system maintains the vehicle speed in
response to the speed set by the driver or in
response to speed requested by the ACC function
The ACC controller controls the throttle and
brake actuators to have effective brake and
throtle control

15. FCW modes
FCW with ACC In this mode the FCW does not
expect the ACC to provide any
inactive braking.
In this mode the FCW warning
algorithm takes into account the
FCW with ACC braking function that the ACC can
active provide. An alert is produced if
the ACC braking authority is
inadequate to prevent a collision.

18. ACC off The ACC system is not functional. This is
entered whenever the ignition is on and the
ACC is turned off.
Standby The system is waiting to take control of the
without throttle and brakes. This is entered when
speed set both ignition & ACC are turned on. System
can be activated by pressing set button. After
vehicle has reached a minimum speed.
Standby with Waiting to take control of throttle & brakes.
speed set. A set speed is established before.
Maintaining ACC attempts to reach & hold a specified
speed. speed.here set speed can be increased or
decresed by pressing resume/accel or
set/coast buttons

19. Maintaining Here ACC system attempts to reach and
headway hold specified headway. Set can be
increased or decreased by pushing or
tapping on resume/accel or setr/coast
buttons.
Manual Here driver is pushing on the throttle to
throttle force the vehicle to go faster than cruise
override control function would command.
Under Here ACC has reduced the vehicle speed
minimum below a certain cruise speed as a slow
speed while vehicle is ahead. ACC will not cause the
active. vehicle to accelerate. Driver get message to
control of vehicle.

20.  Conveniently manages vehicle speed &
headway gap.
 Complements vehicle styling.
 Makes cruise control more usable in more
traffic conditions resulting in more relaxed
driving experience.
 Operates under wide range of environmental
conditions (dirt, ice, day, night, rain or fog)
 Low false alarm rate.

21.  Radar-based sensing for optimal
performance.
 Sensor hidden behind front grill or fascia.
 Best available detection & tracking
performance.
 Manages vehicle speed & headway gap using
throttle control & limited braking.
 Automatically notifies driver of a blocked
sensor via displayed message.
 Excellent following distance & speed control.

22.  Improving the ratio of correct recognition
instances versus false positives.
 Interested in improving performance by sensor
fusion.
 GPS & digital maps can help tasks such as lane
following, particularly during visibility conditions.
 Developments in telematics solutions.
 Vehicle-vehicle & vehicle – road communication
enables exchange of information regarding
vehicle speed, acceleration, heading direction &
speed limit.

23.  In the field of automobiles.
 For the purpose of safety driving.
 Developments in telematics solutions.
 For the development of more sensors used in
this purpose.
 For the field of robotics.
 For speed controlling purpose.

24.  The development of robotics have lead to the
ACAS program.. On the completion of this
program, we get more intelligent vehicles.
The phase of driving will also change ; a hand
free driving.
