Hy-HIL : new test platform for the development of hybrid vehicle

다국어 초록 (Multilingual Abstract)

D2T, RENAULT, IFP, LMS and G2ELAB launched together the HyHIL project, a new test platform for the development of hybrid vehicles. HyHIL uses a suite of generic tools, such as D2T’s MORPHEE 2 automation system, to reproduce and assess the complex architecture of hybrid vehicles in a unique and flexible way.
Combining an IC engine with an electric motor is complex: it increases the number of parameters to be calibrated during the development. This means increased time and cost, while the market demand is asking for their reduction. HyHIL helps to solve this problem by defining the best architecture of a hybrid powertrain at the early stages of development. The platform evaluates hybrid powertrain concepts and the benefits of different levels of hybridization in an engine test bed, thanks to real-time simulations developed with LMS’ AMESim simulation platform and executed by D2T’s MORPHEE 2 automation system.
MORPHEE 2 executes real time models required to simulate both hybrid vehicle and driver. The MORPHEE 2 flexibility allows switching easily between the three hybrid architectures retained for this project:
- "Pure thermal" mode, with simulation of an alternator-starter.
- "Stop & Start" mode, with simulation of the engine’s frequent stop/start phases.
- "Hybrid" mode, with simulation of electric propulsion, energy recovery during deceleration phases and battery recharging.
These architectures have been tested over several standard driving cycles (NEDC, FTP, Artemis, etc.) using an energy supervisor developed by IFP which is sufficiently generic not to require specific calibration.
The results obtained on the engine test bed were compared to results obtained on a real vehicle; the simulation proved to be a very realistic representation.
Simulation, with the use of an environment such as AMESim and MORPHEE 2, offers a real way to assess complex powertrains without the need to manufacture the powertrain or even the complete car.
