Abstract. Every motorist dreams of a car that will take the stress out of parking by finding a
suitable space and then maneuvers itself into the space with minimal assistance from the driver.
This paper describes a parking helper device using ultrasound sensors, mounted on the car, to
monitor both sides of the street for a suitable parking space, and when a large enough parking
space is detected, the helper instructs the driver to stop the car and guides him/her via a display
screen and voice about steering maneuvers which will ultimately result in the car being properly
parked in the given parking space. Ultrasound sensors mounted on the front and rear bumpers of
the car will ensure that a safe distance is maintained to other vehicles and objects and the driver
will need to operate only the accelerator and the brake pedals. A warning signal sounds if the
vehicle gets too close to other objects in the parking space.

In highly populated areas it can be difficult to find available parking spots. In
addition to traffic rushing by and multiple drivers competing for the same space,
another challenge is that parking spaces are tight and difficult to maneuver into. This
paper presents design and implementation of a device called “Parking Helper” which
can detect a parking space and then instruct the driver to park into the space with
minimum effort. The Parking Helper can be used as a tool to help people with
disability, beginner drivers, and even just for the fun of it. When a driver wants to
park, he or she switches the system ON to start the parking process. Ultrasonic sensors
are used to detect the space and the system calculates the size of the space and
compares it with the size of the car. After that the driver is informed through LCD
screen and speakers to stop the car and follow the steps which lead him or her to park
the car in the parking space safely and with minimum effort. In addition, the device
gives the driver a warning message when the vehicle gets too close to other objects in
the parking space.
