With the integration of connected services, connected vehicles, autonomous driving, mobile devices and third party app development, along with the distributed nature of an in-vehicle infotainment system, testing such systems face many challenges. These are amplified by the global scale of engineering and development efforts.
KPIT brings to you a series of perspectives on In-Vehicle Infotainment – specifically around testing the embedded software that makes up the heart of this subsystem.
Topic 1: Landscape of Infotainment Testing Challenges
Build a configurable test system – A crank waveform generator may be present in some configuration, not necessarily in all
Test system must be able to manage data logger loading and facilitate analysis – Switched Ethernet with 100MBPS, Surround View, Camera interfaces for analysis
Wireless / OTA connections must be facilitated
Back office services are available for testing
Configuration & Setup
Test system to provide a la carte capability when developing executable test cases
Test system must present negligible performance impact on system under test. More important as we see more embedded in-vehicle deployment of Android
Support ECU re-flash for software verification and validation + testing re-flash functionality
Democratize secret sauce
Test case development can be driven by different models . Have appropriate interfaces and processing. – State transition diagrams, State space models, Golden sample executable models, signal processing algorithms etc.
Test case generation usable by SMEs. Not requiring to deeply understand programming test system ( like device drivers, interface to drivers)
Make functional limitation of test systems known to all.
Traceability built simplistically for people to communicate test strategy and execution effectiveness
Real time communication + Aggregation of pass/fail verdicts at various stages of testing
