Scaleo Chip and IFP Energies Nouvelles Roll Out OLEA in a Plug-in Hybrid Car

June 23, 2014

Scaleo chip and IFP Energies nouvelles (IFPEN) unveiled "FlexHybrid powered by OLEA", a plug-in hybrid electric vehicle (PHEV) driven by OLEA microcontrollers.

According to a release from the company, Scaleo chip has recently introduced OLEA, its new family of powertrain microcontrollers embedding two technologies surpassing the current market solutions: AMEC (Advanced Motor Events Control) and SILant (Safety Integrity LeveL agent) technologies provides hardware flexibility, timing events predictability, processing performance, functional safety and design cycle reduction.

IFPEN noted it has activities covering the fields of energy, transport and environment. Among these domains of expertise and know- how, IFPEN has an experience and technologies on the improvement of internal combustion engines and powertrain electrification, development of control laws and energy optimization algorithms. Based on its work on fuel economy analysis, IFP Energies nouvelles has recently released an eco-driving mobile application for the general public.

Scaleo chip, IFPEN, Continental and CEA added they partnered within the NextSTEP program (Next Solution for Thermal and Electrified Powertrain), to demonstrate the ability of Scaleo chip's OLEA microcontroller's to control the plug-in hybrid electric vehicle, called FlexHybrid. This program was also actively supported by Bpifrance, the French public investment bank.

Within the NextSTEP program, three powertrain electric control units (ECU's) using the new OLEA microcontrollers were designed: the first ECU handles the spark ignition engine and automated manual gearbox controllers, the second ECU includes the power converters and electric motor controllers, and the third ECU hosts the hybrid vehicle supervisory controller, the transmission control law and the electronic/electrical components manager. A rapid prototyping tool chain enables automated software and hardware code generation for the embedded cores and the programmable logic of the OLEA microcontrollers. This code generation flow allows complex algorithms porting from MATLAB/Simulink models.

"Our strong and fruitful partnership with IFPEN has concluded with this first prototype car which demonstrates all the benefits of OLEA from end-to-end integration: silicon, software, and system in a vehicle" says Bruno Paucard, President and CEO of Scaleo chip. "Moreover, it provides to OLEA customers fast application development and scale-up with implementation examples in ECU design, software development, AMEC development and calibration with OLEA".

According to Gilles Corde, program director at IFPEN, "Working with a leading technology company on a very innovative product such as OLEA, generated a strong motivation on IFPEN researchers. We designed a modular OLEA-based electronic control unit which runs our algorithms dedicated to the plug-in hybrid vehicle control. We were able to contribute to a tangible innovation that emphasizes our ability to support OLEA technologies. IFPEN is proud of this rewarding collaboration with Scaleo chip and this successful project marks the beginning of a longer-term partnership between our two companies."

Scaleo chip is a fabless semiconductor company.

IFP Energies nouvelles (IFPEN) is a public research and training player.
