INTRODUCTION:

• The SafeTexter is a new and innovative step to automotive safety.

• The SafeTexter is a way of protecting people from accidents due to texting while driving.

• The SafeTexter will change the future.

TODAY’S SITUATION

• One of the biggest issues that has arisen

• Texting while driving • Statistics

• 2011• 23% of all collisions involved cellphones accidents.

• Equivalent to roughly 1.3 million collisions.• 6 times more than driving while intoxicated

GOAL AND OBJECTIVE

• Goal

• Limit phone usage while driving.• By limiting the incoming and outgoing texts, as well as limiting

the application usage that can cause a distraction.• Using the on-board sensor of the cellphone to speak to the

vehicle and perform certain tasks.

• Objective

• Make driving safer by limiting the driver from cell phone usage.

TASKS

• Understand how a vehicle’s operation can be manipulated through an FPGA, and get a background on the android app development process.  

• Configure the FPGA and android app to interact with each other and the vehicle through Bluetooth and relay circuitry. 

• Test that the vehicle starts at the appropriate time and that the app correctly blocks access to specified functionalities of the user’s phone. 

• Demonstrate that the vehicle will start only when the app is connected and actively blocking access to social media/texting. 

• Document the progress and degree of success of the project.

OUR APPROACH• FPGA to control the vehicle starting system.

• Android application to utilize Bluetooth interactions with the FPGA

• When the Bluetooth is connected:• The vehicle will be able to start

• The user's cellphone will lock certain functionalities of the phone.

• Keypad to bypass SafeTexter• In the event the user does not have their phone

• In the event the cell phone is low on battery with no way to charge

• If the phone comes disconnected during vehicle operations• User will be warned and a timer will start

• If the issue is not resolved within the given time, then the fuel pump will become disconnected

• The vehicle will act as if it was out of gas.

THE DESIGN• Hardware Side

• FPGA Board• Add-on Bluetooth component

• Add-on keypad component..

• Relays

• Software Side• Android ADT

• JAVA language

HW: PLACEMENTS

HW: RELAY CONFIGURATION

HW: STARTER CONFIGURATION

HW: FUEL PUMP CONFIGURATION

SOFTWARE SIDE• Two types of window activities

• Teenager side• Hidden program that runs on the background

• Locks functionality to text messaging and social media when paired to the SafeTexter module.

• Text messaging with be “turned off” by setting s SMS-listener to a high priority and canceling the broadcast temporarily.

• To block social media, the app will need to utilize a custom launcher to control access to them.

• Parent side• Settings and configurations

• Sets keypad code

• Turns the SafeTexter module on or off.

HW COMPONENTS: NEXYS 3 FPGA BOARD

HW COMPONENTS: PMODBT2 BLUETOOTH

USE CASE: STATE DIAGRAM

RELATED WORK

• Only one application in existence that uses hardware

• Doesn’t actually block any applications

• Others do exist but are reliant on GPS tracking and a speed over 20 mph

• This leads to problems if you are a passenger in a vehicle as well

• Also doesn’t work correctly in slow traffic
