The project is developed to avoid the human errors while taking a reverse extensively used for parking the vehicle. In this project we use ultrasonic sensors which can efficiently detect the obstacles and the solenoid valve perfectly controls the braking system by using Arduino programming. This project has reduced the tension of the driver and also reduced the cost involved in the concern. The project has been designed to perform the required task by taking minimum time.

2. OBJECTIVE
 In this world, automation of various systems have been designed to
reduce the human error and time required to complete a task. Vehicles,
particularly four wheelers are very difficult to drive in the reverse
direction.
 For this purpose we have developed AUTOMATIC REVERSE
BRAKING SYSTEM (ARBS) which includes ultrasonic sensor,
solenoid valve ,flow control valve, spring operated single acting piston
cylinder arrangement .
 The main objective of our project is to provide comfortness to the driver
and automation of the vehicle can erase away the human errors.

3. LITERATURE REVIEW
 “International Journal of Science and Research (IJSR)” A journal was
published by “Divya Thakur and A. P. Thakare” (Electronics and
Telecommunication department, Maharashtra, India), January 2015
The journal was based on FPGA (field programmable gate array). FPGA
which act as a controller logic is designed with the help of FSM (Finite State
Machine). We have replaced FPGA by using valves and piston cylinder
arrangement (i.e. FGPA is replaced by pneumatic circuit).
 Volvo is all set to launch its new XC60 SUV which will sport laser assisted
braking which will be capable to sense a collision up to 50 mph and apply
brakes automatically.

4. PROJECT DESCRIPTION
 The ultrasonic sensors are placed at the rear end. The sensors are turned
ON when the reverse gear is engaged. When the sensor senses any
obstrucles, it switches ON the solenoid valve using Arduino
programming.
 The solenoid valve operates the pneumatic cylinder. The flow control
valve controls the flow of air to the pneumatic cylinder. The pressurised
air can be obtained by a compressor or an air tank.
 The spool change in solenoid valve operates the double acting pneumatic
cylinder .The pneumatic cylinder subsequently pulls the brake lever.
Hence the vehicle is bought to static position.

13. MERITS AND DEMERITS
MERITS:
 Brake cost will be less.
 Free from wear adjustment.
 Less power consumption.
 Less skill drivers is sufficient to operate.
 It gives very simplified operation.
 Installation is simplified.
DEMERITS:
 Additional weight to vehicle
 Sensor may not work in winter season

14. CONCLUSION
 The project is developed to avoid the human errors while taking a
reverse extensively used for parking the vehicle. In this project we
use ultrasonic sensors which can efficiently detect the obstacles and
the solenoid valve perfectly controls the braking system by using
Arduino programming.
 This project has reduced the tension of the driver and also reduced
the cost involved in the concern. The project has been designed to
perform the required task by taking minimum time.
