Libraries Description

OLEA® LIB is a library of advanced software optimized for OLEA® and dedicated for the control of Hybrid (HEV) and Electric Vehicles (EV). OLEA® LIB is packaged into three levels of integration selectable upon the application needs. Libraries comes as building blocks available as Reference and Target Models Toolbox for MATLAB Simulink, or as HDL pre-defined blocks, and tuned for best used of AMEC FLU. Models out of OLEA® LIB are directly usable within OLEA® COMPOSER for MiL simulations and automatic code generation. By using OLEA® LIB, developer's reduce drastically the time required to optimize algorithm's porting on OLEA® while improving drastically performance, quality and safety of their system
