3. INTRODUCTION
 The main target for this project is that, cars can run reverse automatic
braking due to obstacles when the sensor senses the obstacles.
 The braking circuit function is to brake the car automatically after
receiving the signal from the sensor.
 Need of Automatic Reverse Braking
 Benefits to the Customers

4. LITERATURE SURVEY
 The Reverse Alert System was first developed by Surveillance Guard
Corporation (SVG). It was the world’s first aftermarket automatic
braking system that can be fitted to any vehicle.
 This system begins with ultrasonic sensors that were fitted at rear of
the vehicle. These sensors detected an object at 1.6m, a signal was
sent to a solenoid located at the front of the vehicle.
 The Reverse Alert Technology was installed on following vehicles:
• Two Ford Ranger Light Commercial Vehicles (1 x 1.6m and 1 x 2.5m
systems) and;
• Two Hino Trucks (both equipped with the 1.6m system) – EWP and
Line Truck.

5. METHODOLOGY
Fig. (a) Block Diagram of an Intelligent Reverse Braking System.

6.  IR transmitter transmits ultrasonic waves continuously.
 When a car gets too close to an obstacle, the ultrasonic waves reflect
back which is then received by the IR receiver.
 This control unit switches ON the solenoid valve. These complete
processes are electronic based which require electric supply.
 A continuous supply of compressed air through tank is supplied to
solenoid valve.
 When signal from control unit is received by solenoid valve,
compressed air is supplied to pneumatic single acting cylinder.
 Then the piston moves forward and consequently brake is applied to
the wheel. This stops the car and accident is avoided.

7. COMPONENTS AND
DESCRIPTION

System.

8.  A control unit supplies the power to the IR sensors. A 24V DC
supply is required for IR sensors.
 Sensor unit consist of IR transmitter for generating the
ultrasonic rays and IR receiver to receive ultrasonic rays when
they reflect back from the obstacle and is then sent to control
unit.
 The control unit then determines the distance of obstacle from
the car and if the distance is within certain range it sends
signal to solenoid valve.
 A continuous supply of compressed air is required by solenoid
valve to operate the brakes whenever needed.
 It converts the mechanical energy from motors and engines
into the potential energy through compressed air.
 When flow from the input port enters into the cylinder, due to
the pressure force the piston moves forward to compensate the

9.  Once the pressure from the input port is withdrawn, due to
spring in the cylinder the piston moves backward. Hence for
reverse motion, no force is required.
 This completes the braking processes. The brake is
continuously applied till signal from IR receiver is obtained.

10. ADVANTAGES
• Simple design.
• Less operating force is required.
• Greater safety in Reverse Braking.
• Automated operation.
• Can be used in running as well as Parking Mode.
• Quick response and easy operation.

11. LIMITATIONS
• Relatively low accuracy.
• Proper maintenance and checkup required before use.
• Creates Noise.
• Preferred for light weight operations.

12. FUTURE SCOPE
 The actual importance for the safety increases the value of this
system.
 Automobile industries are about to launch various intelligent
braking systems to increase the safety of customers.
 National and international organizations evaluate Motorcycle
ABS as an important factor to increase safety and reduce
motorcycle accident numbers.
 The European Commission passed legislation in 2012 that
made the fitment with ABS for all new motorcycles above
125cc to be mandatory from 1st January 2016.

13. CONCLUSION
 The Intelligent reverse Braking System, if executed in auto it
deflects heaps of mishaps and can spare human lives and property.
 Execution of such a propelled framework can be made mandatory
like wearing of safety belts with the goal that mischances can be
deflected to some degree.
 The fate of car security is more than simply building up another
innovation; it is moving the way to deal with wellbeing.
 INTELLIGENT BRAKING SYSTEM approach speaks to a huge
movement from the conventional way to deal with wellbeing, yet it
