OLEA T222 FPCU is a safe and real-time automotive control solution. OLEA FPCU T-222 is the industry’s first Field Programmable Control Unit (FPCU), a unique semiconductor architecture defined as a combination of accelerated parallel processing and hardware flexibility for critical real-time control and ASIL D level functional safety. OLEA FPCU is designed to process critical information faster with 100% predictability and accuracy as needed by the next generation of EVs and HEVs.

The OLEA APP INVERTER addresses the need of EV/HEV manufacturers and automotive Tier 1 suppliers for short time-to-market solutions with a quick start into the development of applications for best-in-class control of electric powertrains.

The application is based on the OLEA T222 FPCUs parallel architecture, which allows extremely high-performance real-time control of advanced power electronics and electric motors. It provides efficient and safe torque and speed control using Field-oriented Control (FoC) and variable Space Vector Pulse Width Modulation (SVPWM) algorithms. The modular software can be adapted to a large variety of customer applications, including low- or high-voltage systems, PMSM and WRSM multi-pole/multi-phase motors. The high controller performance supports MOSFET and IGBT power transistors, and is particularly suited to the latest SiC and GaN-based inverter technology. Exploiting the programmable and parallel hardware of the OLEA T222 FPCU chip allows the use of real-time control loops and switching frequencies up to 100 kHz. The application has two independent stacks—one for control and one for functional safety—designed as AUTOSAR complex device drivers. Thus, the application is ready to satisfy the increasing demands of next-generation electric powertrains without software bottlenecks.

To support customers' developments, the OLEA APP INVERTER platform enables a fully integrated model-based design flow along the development cycle, including Model-in-the-Loop and hardware-in-the-Loop simulations, and features easy calibration and validation thanks to its native ASAM standard support.

During this presentation, we will explain and illustrate in depth the algorithm that enables Silicon Mobility to deliver applications that optimize the energy efficiency of EV and HEV powertrains.
