Model Based Development of Seating Comfort System

Customer:

Tier-1 supplier for automotive and industrial products.

During the Model Based Development of their latest Seating ECU, our customer was confronted with a unique challenge related to controller memory.
For this project, the customer created floating point library model which occupies a large part of on-chip memory, because of the ‘double’ data type.
Since this new Automotive Seating ECU featured some very advanced seating comfort and control functions, floating point library modeling turned out to be an inefficient method with respect to on-chip memory consumption.
To resolve this issue within time and budget constraints, the customer was on a look out for an embedded software partner with in-depth expertise in Model Based Development.

During the technology workshops, our automotive software development team and the customer agreed to convert the floating point models into fixed point models.
Since there were multiple blocks of models that required the conversion, our embedded software developers also started working on the automation tool to make the entire process more efficient.
Our automotive software team leveraged the in-house designed automation tool for all the future releases.
Due to Automation of the whole process, the development time was reduced from several days to a 2-3 day process.
The tool ensured automation of the following steps:
- Model Initialization file creation.
- Interface Files Creation.
- Fixed point code based Model creation.
- Code generation.

Our automotive software development team’s pro-active approach helped us to identify the scope of automation. This ensured reduction in the turnaround time for the new releases.
The automation tool reduced the overall process time by around 80% and has substantially improved the accuracy of the work products.
As per the client requirement, with minimal changes, the tool can be reused across multiple MATLAB/Simulink projects.
