Business Context

The client a multinational manufacturer of passenger cars, light commercial vehicles, components and production systems wanted to develop a control software for its Model year 2019 architecture. The OEM wanted to cover requirements of all functionalities within the architecture with failure mode analysis.

KPIT’s Approach and Solution

KPIT developed a complete framework and process for System & Function Requirement development and ensured that the framework was developed keeping in mind HIL and Vehicle Level Testing. In addition to the framework, KPIT provided insights to mitigate design failures and enhance performance.

Vehicle Function Development

  • Studying the requirement document, understanding the function behavior
  • Preparing function block diagram & Defining working conditions and functional requirements
  • Defining/Updating diagnostic and recovery requirements
  • Feeding the Output as Vehicle function requirement document in DOORs

System DVP&R Development

  • Detail study of the calibrated parameters and threshold affecting the function behavior
  • Identifying test objective for each requirement (to be tested) and preparing test cases
  • Clearly specifying the acceptance criteria for each test cases

Conducted System DFMEA that included;

  • Creating a DFMEA document, with RPN number calculated for all the malfunction
  • Providing recommendation for design changes

System Architecture Diagram included;

  • Architecture System Boundary & EE requirements

Customer Benefits and Impact

  • KPIT worked on 40+ complex functionalities simultaneously ranging from engine, transmission to drive line
  • KPIT took complete ownership of the system requirement development from offshore, and provided consultation to bring performance enhancements in the design
  • Systematic reviews and collaboration with multi-functional teams at every step of the system engineering process ensured transparency and robustness
  • Key resources with INCOSE* certification ensured superior quality delivery
  • Achieved high level customer satisfaction in the deliverables with delivered defect density of zero

Subject Matter Expert – System Engineering, KPIT

“DFMEA is a key activity in the System Requirement Development. Main challenge is to have a resource pool with
experience from embedded to quality processes. KPIT arranged for DFMEA brain storming sessions with the Cross
functional team including System Engineers and other stake holders i.e. control engineer, Quality engineers etc. for
finalizing the Cause & Effect analysis, Failure detection strategy, Control decision for mitigation, Severity rating , Occurrence rating , and Detection rating etc.”
