Step 1 (MIL): Early model development phase in MATLAB/Simulink

In the context of model-based software development> Functions of the application are tested in an iterative process

> The model is executed iteratively in Simulink

> Initial parameter calibration is necessary

With the CANape Option “Simulink XCP Server”> CANape can be used as a familiar GUI for the models running in Simulink

> Access to the model running in Simulink via XCP

> CANape projects/configuration can be reused in a later development phase

Use CANape During The Entire Development Process

Solution

CANape Option “Simulink XCP Server”

Advantages:

Algorithms can be optimized in an early development phase

No hardware is available

Full access to all signals/parameters

Use of measurement/calibration window

All CANape features (e.g. measurement analysis, calibration data management, …) can be used

Better usability than in MATLAB/Simulink

Use of captured real data in Simulink

Working with standards

How to use the Simulink XCP Server:

Only one block must be added

Configure Simulink XCP Server

Automatic file generation

A2l

Model explorer

CANape project

Start CANape project within Simulink

Simulink model behave like virtual ECU

Step 2 (SIL): First Rapid Prototyping

Initial development of model is finished> Model testing with real data (online/offline) in real time

> The model is executed on the PC (DLL)

> Parameter calibration with real ECU environment

CANape/vSignalyzer Target and Simulink Coder generates Windows DLL> Visualization and cascading of DLLs via “Algorithm Designer” window in CANape> Connect real data from various sources to the DLL input/output ports

> Measurement and calibration by integrated XCP driver

Use CANape During The Entire Development Process

Solution

CANape/vSignalyzer Target

Advantages:

Model/algorithm can run with real data (online/offline)

CANape acts as interface to real data

No HW and no MATLAB necessary

Model can be used by multiple engineers

The model itself can be measured and calibrated (like an ECU)

No rebuild of the model necessary

All CANape features can be used

Working with standards

How to use CANape/vSignalyzer Target:

Add CANape input/output blocks to the ports of your model

Configure the CANape Target

Generate code/DLL

Add the DLL to CANape and connect the ports to real data

Optional:

Create a device with the generated Simulink DLL & A2L

Measure and calibrate the DLL

Step 3: SIL, HIL and target platform

Model testing on real time hardware and target ECU> Fast modification of ECU algorithm, without complete ECU SW generation/flashing

> HIL on test benches or real car verification

> Final parameter calibration and variant parametrization

DLL execution on real time hardware VN8900> Configuration in CANape execution on external hardware

CANape/vSignalyzer Target DLL as bypass/fullpass solution

Reuse of CANape project/configurations > One calibration tool from step 1 to step 3> Same configuration for final validation in

cars and first model development

Use CANape During The Entire Development Process

Bypassing

16

Fast modification of ECU algorithm or code segments without

complete ECU SW generation

flash re-programming

The existing ECU hardware has insufficient RAM, flash ROM or CPU speed

Possibility to test the new application

Switching between original ECU application and the new algorithm

Compare both under real conditions

Vector´s Solution:

Bypass execution on the PC or on the real-time VN8900 hardware

High-end ECU access with our VX1000 solution

High amount of signals or increased sample rates

Time synchronous write and read

All signal sources in CANape can be used as additional inputs/outputs
