ABSTRACT

Android Auto is a telematics standard developed by Google to allow mobile

devices running the Android operating system (Lollipop and later) to be operated in

automobiles through the dashboard’s head unit. Android Auto was announced on June 25,

2014, at Google I/O 2014.

The standard will offer drivers control over GPS mapping/navigation, music

playback, SMS, telephony, and web search both touchscreen and button-controlled head unit

displays will be supported, although hands-free operation through voice commands will be

emphasized to ensure safe driving. Compatible apps include Google Maps, Google Play

Music, MLB at Bat, Pandora Radio, Spotify, Songza, Stitcher, iHeart Radio.

Android Auto is part of the Open Automotive Alliance, which was announced on

January 6, 2014, and is a joint effort with 28 automobile manufacturers and mobile tech

supplier Nvidia. The first cars supporting Android Auto will be released in late 2014.

The aim of Android Auto is to extend the functionality of an Android mobile

device in an automobile to the dashboard's head unit. In order to use the system, users must

be running Lollipop on their mobile device and must own a vehicle supporting Android

Auto. The driver's Android device connects to the vehicle via USB cable.Rather than running

its own operating system, the head unit will serve as an external display for the Android

device, which runs all of the software, by presenting a car-specific user interface built into

Lollipop.

INTRODUCTION

Android is proven developed platform for many devices,at present we are having so

many devices that are running over android platform like mobile phones,tablets,tvs and

android wears like watches and google glass.

Traffic in present days increasing rapidly.Usage of cars also increasing day by day on

an average,we use cars 1hr per day and a smart phone user checks his mobile phone 125

times per day.It would be more interactive if we combine these two.

A recent survey gives a report that 25% of the accidents are happening to due to the

usage of mobile phones while driving.We use mobile phone while driving for attending

incoming calls and making out going calls and reading and replying for messages.These cases

distract the driver from driving the car so because of this reason most of the accidents are

happening.

A solution for this problem is to integrate the mobile phone and the car,building a

platform that support both the car and the mobile phone this could be done with the mobile

phone.

Smart phones that are used mostly based on IOS and Android.Apple’s IOS has

developed a platform for this solution by introducing car play.Now it’s turn for the

GOOGLE’s Android.

Google has Extended the mobile platform to the car using ANDROID AUTO.This

android auto is integrated with the cars in-car IVI system so that user can interact with the

mobile phone with the car’s display.so that user can perofrom all his operations without

taking the phone in to the hand.

Android auto is supported with target sdk as Android 5.0 Lollipop and above and the

cars also needs to upgrade their systems that support Android auto.

So they have formed an OAA(Open Automative Allicance) where the automobile

manufacturers and the software companies work collaratively to develop a platform that

support both the devices.

OVERVIEW

Google has started working with auto manufacturers for building the platform.It has

several releases.

PROTYPING IN 2005

Prototyping is the process of building a model of a system. In terms of an information

system, prototypes are employed to help system designers build an information system that

intuitive and easy to manipulate for end users. Prototyping is an iterative process that is part

of the analysis phase of the systems development life cycle.

During the requirements determination portion of the systems analysis phase, system

analysts gather information about the organization’s current procedures and business

processes related the proposed information system. In addition, they study the current

information system, if there is one, and conduct user interviews and collect documentation.

This helps the analysts develop an initial set of system requirements.

Prototyping can augment this process because it converts these basic, yet sometimes

intangible, specifications into a tangible but limited working model of the desired information

system. The user feedback gained from developing a physical system that the users can touch

and see facilitates an evaluative response that the analyst can employ to modify existing

requirements as well as developing new ones.

SEND 2 CAR IN 2007

You can send a place in Google Maps to your car using the Send to Car feature.This

feature's only available for certain participating car manufacturers.

Add your car

1. Go to https://www.google.com/maps/sendtocar.

2. Click Sign in and enter your account information.

3. Click Add car or GPS device.

4. Select your car type from the dropdown menu. For example, “Audi” or “Nissan.”

5. Type in your account ID provided by your car manufacturer in “Account ID” field. Your

ID can be found by signing into your car manufacturer’s website.

Click to see an example.

6. [Optional] Type a name of your car to remember it more easily.

7. Click OK.

Send a place to your car or navigation device

1. Open Google Maps.

2. Search for a place.

3. Click Send to car in the card that appears below the search box.

4. Confirm the place and device details in the dialogue box that appears. Click the picker

with your default car/device to change between saved cars/devices. You can rename the

place if you want.

5. Click Send.

6. Follow the prompts in your car or on your device to see the place.

AUDI EARTH IN 2009

Google and Audi take Google services in the car to the next level.Introduced Google

Earth into the car for Navigation using Internet.

Nowadays, it seems like everything is connected to the Internet: mobile phones,

laptops, netbooks, portable game consoles, personal navigation devices. Think of how

applications such as Google Maps for mobile have changed the way you find locally relevant

businesses or addresses, or real-time traffic along your route. We can even get online from

35,000 feet while on an airplane, or while traveling at 300 km/h on a train. Google has

worked with the automotive industry to bring services like Local Search into cars in the past -

now we're teaming up with Audi to bring an entirely new type of technology into the car:

Google Earth

PLACES API IN 2010

Google has begun opening up access to a new Application Program Interface (API)

called the Places API. Developers building apps that include a "check in at this place" feature

can use the Places API to search across all the places users might check in for basic

information like business name, address, phone number and other descriptive information.

That information will be editable by the businesses listed and no caching of data is allowed,

so apps will have to ping Places regularly for real-time data.

These are the cloud based solutions.

In 2014 Google has introduced ANDROID AUTO .

ARCHITECTURE

The Architecture of Android auto is a bus type architecture.Android auto protocol is

used to communicate the phone with auto.In the phone all the API’S are placed that are

required to communicate with the car like Media API,Notification API,Voice API,Messaging

API,these are integrated with the car play services.In tha car Input,Display,Audio,Sensors are

configured with the same play services.For performing an action with android auto the

required signals are exchanged between the phone and the car.

Signals are transferred from phone to the car with the usb.The data bus which is

required to transfer the data for the operation is enabled and the other buses are

disabled.Android auto service in the phone transfers the data with auto protocol and android

auto receiver library in the car accepts the input and perform operations.

IMPLEMENTATION

NAVSTEP:

Navstep is the first step that was taken to integrate the smart phone to the car.Here in

this step we need two devices one is smaller which can be our smartphone and the other is

larger more probably a car’s display,for this choose a Tablet.

In the NAVSTEP transfer of data should take place between the smartphone and the

tablet.Bluetooth can be used to transfer the data from the mobile phone to the tablet since

they are very close and are placed side by side.

Navigation data has been transferred from the mobile phone to the smart phone using

cloud.Smart phone sends the data to the cloud and tha tablet receives the data from the cloud.

This was the first step taken by the developers.

NAVCAST:

It is some what more than the NAVSTEP.It transfers audio and picture data from the

smart phone to the tablet.To work with low latency,it is not possible to transfer data with the

Bluetooth so we need a new type of data transfer,it can be with DATACABLE.

Here when we transfer the data from tablet to the smart phone we need to do Full off

screen Rendering which makes more sense while transferring the data.For performing this it

should be fast and latency should not increase for this purpose we have choosen data transfer

through DATACABLE.

We have used the USB here for higher throughput.

This is the second step taken by the developers.

ANDROID AUTO:

From here onwards the actual building of the android auto takes place.Here all the

application stack that is present in the car’s display needs to be send to the smart

phone.Which is the turning point of the development.

In this step places the smart phones audio,messaging and maps on to the car’s display

this could be done by developing a special mode that support both the smartphone and tha

car’s display this is what known as android auto.

There are some apk’s which could support both the smart phone and the car’s

display.And developers are allowed to use these apk’s for development. This will project the

smartphone messaging,audio,maps,contact&dialing on to the car’s screen.

We can upgrade the android apk from the GOOGLE PLAY.This was the third step

taken by the developers.

IN-CAR:

This was the last step in the development. Partnership with the car manufacturers. For

this they have formed and OAA(open automotive alliance) where car manufacturers and

software developers work each other for developing a secured platform.In the OAA around

30 car manufacturers actively participated for developing the car’s system that support

android auto.Volvo is the first company that released the first car that support android auto in

October 2014. Thus android auto deployed on to the car

APPLICATIONS

Android auto comes with many exiting features.It gives almost all the phone’s features to the

car.So that it will give both entertainment and services to the user.

Android Auto is not an embedded operating system, but rather a “projected” system, which

means that smartphones using Google’s Android operating system can be plugged into the

car and operated using the car’s controls and display screen.

As of now Android auto has 5 exiting features for the users.

1.MESSAGING

2.CALLING

3.MEDIA

4.GOOGLE MAPS

5.GOOGLE NOW

These are the 5 features that Android auto provides to its users.

1.MESSAGING

Messaging is the dangerous activity that should not be done while driving,it is the

major reason for most of the accidents.To avoid that Android auto comes with speech out and

talk back technology by which user can read the messages and reply to them without

removing hands from the steering.

When an incoming message is recieved a pop up will be seen on the car’s display,it

will asks the user to read the message or not,if user allows it to read the message then it will

speak out the message.After that user can ask for reply in two ways.One method is using

voice recognizer and the other by pressing the push button on the steering then he can dictate

the message to the system,after the dictation also it will read out the message and re-confirm

the dictated message.After the approval from the user it will send the message to a particular

contact.

Android auto comes with builtin Hangouts messaging application and developers are

allowed to extend their messaing applications that support android auto.

2.CALLING

Calling is also a main cause for accidents,When we attempt a call while driving the

drivers attention is distracted from the driving so to avoid that Android auto has introduced a

safe way to attempt calls while driving.

A pop will be shown when user recieves an incoming call then user can attempt that

in two ways,One with voice recognition by speaking ‘Lift the call’/’Reject the call’,or else a

button is present on the car steering to lift or reject the call.

After lifting it will directly turn on the speaker and voice is listned by the car’s

speakers.By this user can have concentration on driving rather than the call.

User can also call to a particular contact in his phone by using the voice commands.

3.MEDIA

Android auto has introduced this feature for entertainment purpose.By using media

user can listen to the music in his phone and listen to a radio station by using radio

applications.

Google play music comes in as a default music application,user can also install his

own applications that support android auto.

User can listen to Radio stations by installing some radio applications in his phone

that support andoid auto.

Here also user can access to media in two ways,through voice commands by speaking

‘listen to music’ or by tapping on the screen or the button that is present on the steering.It will

display all the compatible applications in his phone user can pick of his choice.

All the transport controls for music are present on the car steering itself so that he can

play, pause,next, previous,forward, backward a song without removing hands from the

steering.User can access to them with the touch screen on the car’s display also.

4.GOOGLE MAPS

Google maps is the exiting feature of Android auto.Google has completely redesigned

the maps for android auto to fit for the horizantal aspect ratio.

Google Maps is much easier & more visible on a large screen-front & center-on the

mount of dashboard.

It uses car’s Gps,Compass,Gyroscope sensors and wheel speed for displaying

directions more accurately.

User can give his inputs in two ways here,by voice commands he can just tell

‘navigate to a particular place’ and he can select the destination from the touch panel of the

car display.

Google maps in android auto gives directions more accurately and precisely.Biggest

advatages of Google maps, is it uses Fused Location provider.

5.GOOGLE NOW

Google now comes into your rescue whenever you want by just speaking ‘ok

google’.You can ask almost everything google.By using Google now you can always be

connected to google knowledge graph. It is one way of providing inputs to android auto.

By using Google now you can ask to navigate somewhere, call to somebody,message

to any one, play music in your phone, ask anything related to Google knowledge graph like

‘what’s the weather today’ and everything like Google now in your phone.

Google now will be activated at anytime, anywhere, any place to guide the user.

ADVANTAGES

It avoids road accidents upto some extent.

Perform any operation without touching the phone.

More accurate driving directions.

Easy to develop applications for android auto.

Integrated in car itself no external device required.

Continued support by the manufacturers and developers.

DISADVANTAGES

Not supported with the Android mobile phones before Android L.

Not supported to the existing car systems.

Can not play videos.

No other notifications are displayed except the android auto specific notifications

SUMMARY AND CONCLUSION

Android auto is a new trend in the technology.It extends the android platform to the

cars.It is mainly developed to avoid road accidents that occur by the usage of mobile phones

while driving.Android auto is developed by considering all the aspects that are to satisfy user

and not to violate the rules of cars.It is more easy to develop applications for android

auto.Android auto is open source every one can develop applications on their own.
