Offline Platform

What is VEOS?

MS Windows-based

Simulation (and integration) platform

Simulates “Virtual ECUs”

Simulates other models

(e.g., Functional Mockup Units)

No real time (faster, slower, pause)

C code debugging possible

… and more

“yet another platform” (plus extras)

VEOS – A flexible and fast Simulation and Validation Platform

7

PC-based simulation platform for virtual ECUs, plant and environment models

Supports Simulink, C Code, C++ Code, AUTOSAR, and 3rd party models using

FMI standard

Provides possibilities to co-simulate even with proprietary simulators (e.g.

RTMaps, ADTF)

Interfaces to standard calibration and test tools (XCP, XIL-API)

Step-by-Step debug during run time.

FMI: Functional Mockup Interface

One tool-chain for SIL and HIL testing

Too many Tests for SIL? Scalability with Cluster Simulation

Example: Adaptive Cruise Control Test Drive

General Structure: Simulation Cluster

Manager Node: Distributes test

cases, handles measurement

data

Execution Node: Loads test

case, executes SIL test, collects

measurements

Example:

Maneuver: ACC with Cut-In
