Cruden’s ePhyse Net


Cruden is presenting a new interfacing package that allows its automotive OEM and race team customers to run their vehicle models natively, in co-simulation with any of its simulators, at the Vehicle Dynamics Expo 2012.

Simulations created in vehicle modeling packages such as Vi-Grade, IPG CarMaker, veDYNA, CarSim and SIMPACK can now be plugged and seamlessly integrated through their Simulink S-functions. This new ePhyse Net external physics package saves time on compiling code and also saves costs by eliminating the need for the Real Time Workshop conversion package.

Maarten van Donselaar, CEO of Cruden commented, “A big advantage of ePhyse Net is that third party libraries such as Bosch ESP can be used since there is no need to compile code. Customers also have the choice to start with Cruden’s own Simulink Vehicle Model and we still support compiled MATLAB/Simulink-based models using Real Time Workshop and our basic ePhyse package.”

At the expo, Cruden will also provide more information on its extremely detailed customer vehicle model (CSVM). It is built up in MATLAB/Simulink and runs Pacejka 6.1 based tire models that include temperature and pressure dependency and supports dynamic rolling radius. Thanks to the model’s open architecture users can easily modify, add or replace sub-systems.

You can find Cruden at booth V1484, at the Vehicle Dynamics Expo 2012. For full details, go to
