Case Study
AUTOSAR Migration and Integration of
TCM ECU for a Japanese Tier-1
About the Client
The client is Japan’s leading technology group with presence in over 15 countries. This tier1 specialises in designing, manufacturing
and diagnostics of embedded systems in small to medium production run vehicles.
Business & Technology Context
The Tier1 had to supply an AUTOSAR based Transmission
Control Module (TCM) ECU (Engine Control Unit) to a Europe
based OEM’s new production program. The existing ECU was
designed on legacy architecture and the client wanted to
migrate to AUTOSAR compliant ECU. Few legacy components
Validation
were to be retained from the existing architecture. Therefore,
ECU
components. This led to a communication issue between
different components. Tier-1’s expertise was in ECU development but migration required AUTOSAR software expertise.
Tier-1 scouted for a partner who could cater to other requirements of TCM ECU like integration of OEM specific modules,
development of complex device drivers, etc.

KPIT was a natural choice, as it is one of the largest AUTOSAR service providers with a proven track record of successfully implementing
AUTOSAR and allied services to 20+ OEMs and Tier1s.
KPIT has successfully enabled AUTOSAR migration of complex ECUs for multiple production programs. Hence, the Tier1 trusted KPIT for
this engagement.
KPIT’s Solution
After initial system analysis & feasibility study, KPIT experts designed an architecture that could seamlessly support AUTOSAR and
non-AUTOSAR components.
KPIT had to re-architect the application to make it AUTOSAR compatible. The components of this re-structured application had to be
integrated with Basic Software (BSW), Run Time Environment (RTE), and Microcontroller Abstraction Layer (MCAL).

One of the critical parts of this project was the way the application was split for CPU load balancing. Tier1s large application was strategically
split depending on its functionality and criticality into seven Operating System Tasks. This design helped reduce the processor load & thus
the overall ECU performance.
KPIT also provided the following solutions:
• Development of Complex Driver for external solenoid, external EEPROM, external watchdog and integration
• Development of Flashloader
• Bootmode integration
• Development of Tier1 Specific ECU State Manager
• Configuration and Integration of Diagnostic Modules
• Integration with OEM Specific compatibility modules
• Complete Testing with tools provided by OEM

Key Success Factors and Client Benefits
KPIT’s integration and migration services were the highlight of this project. Tier-1 found a single AUTOSAR success partner in KPIT with its
comprehensive services around AUTOSAR basic software. This ensured that the AUTOSAR basic software was perfectly integrated with the
migrated application software. It was not just the stack but the services that ensured success. After all AUTOSAR is all about execution.
