Context

Driving assistant: What for ?

A driving assistant is used by its users to share : ● Traffic lights ● Speed camera (mobile or fixed)● Traffic incidents● Etc.

Genymobile is building many of the next gen driving assistants running on Android, transforming them into full IVI systems.

Doing this means :● Tons of modifications in Android● Sweat● Blood● Tears● Etc.

This presentation aims at giving you our feedback on this specific use case.

Android Modifications

What do we modify and why ?

A driving assistant is not a smartphone : ● Different screen size and orientation● No multitask● Always works● Needs to be fast (real fast)● Reliable● Specific functionnal need (boot on plug, boot time, etc.)● Absolute security

There is some difference with AOSP implementation :● Android is multitask by nature● Android always works (sort of...)● Android is fast (but not enough)● Android is reliable !● Android is also secure !

Android Modifications

What do we modify and why ?

So what did we modify : ● The bootloader● The boot sequence● The Linux Kernel● The Android Framework

○ Zygote○ Dalvik○ System event handlers○ Crash Handlers○ GPS / A-GPS ○ Android UI○ Wi-Fi removing○ OTA○ File system encryption○ File system perception from a computer

● Security

IVI Adaptations

Adaptations to the vehicule environment

Android is a smartphone/tablet operating system so we had to adapt some features for the specificities of the vehicule environment :

● User Interface ● User interactions● Device input methods● Energy saving policy

Genymobile is building many of the next gen driving assistants running on Android, transforming them into full IVI systems.

Android benefits

What are the benefits in using Android ?

Considering the huge amount of work we putted in OS customization, here are some of the key benefits of using Android :

● It's still a Linux● Features● Quick project● Ecosystem● Capacity de deliver a full product at each sprint● OS Customization possibility● CE Experience● Dev community

On a end user perspective, the biggest benefit of using Android is clearly its ecosystem and the consummer electronic experience it gives.

On a OEM perspective, the huge developper community is clearly something that is to be regarded as a huge benefit.

Android for IVI ?

Is Android a good choice for IVI solutions ?

Few numbers : ● 5 out of 10 top purchase decision for car is IVI related (GFK)● Software represent between 35 to 80 % of the added value of a car (Spectrum

IEEE)● More than 1 million Android activations per day

Pro-Android : ● CE experience, smartphone influenced● Ecosystem : tons of applications, developers and a market place ● Development costs are low

Cons-Android : ● No standard - GENIVI supported - IVI stacks yet ● Not as supported and used in IVI world yet● Dependent on Google

Different approaches

What could be done differently ?

We could have buid the solution using different appraoches : ● Use GENIVI Linux base and develop everything on top of it● Use GENIVI Linux base and virtualizing Android ● Use Custom Linux to host a container with Android inside● Use Custom Linux and virtualize applications from different OS
