CANape 6.5

Measurement, Calibration, and Diagnostics of ECU's

Download Datasheet | New Features

CANape is a versatile tool ideal for ECU development, calibration, diagnostics and measurement data acquisition.

Features and Advantages

The primary usage area of CANape is the optimal parameterisation (calibration) of ECU's. During the system's runtime, parameter values are calibrated and measurement signals are acquired simultaneously. The physical interface between CANape and the ECU is implemented over the CAN bus using CCP (CAN Calibration Protocol), its successor XCP, or the KWP2000 diagnostic protocol. CANape with its integrated "Diagnostic Feature Set" offers the range of functions of a full-fledged diagnostic tester. Standards were utilized in designing CANape , and this makes it an open and flexible platform for all phases of ECU development.

Functions

The basic functions of CANape include:

Time-synchronous acquisition of measurement data using CCP, XCP, also via CAN, LIN, and FlexRay, plus via extensive external measurement equipment
User-friendly real-time calibration via CCP and XCP
Efficient offline calibration
Flashing of binary files
Diagnostics seamlessly integrated via KWP2000 and UDS
Powerful calibration data management for comparing, merging, and flashing parameter sets
Integrated MATLAB/Simulink models enable calculation during the measurement or in offline analysis
Environment recognition synchronous to measurement data utilizing video, audio, and GPS

Application Areas

CANape is the versatile tool for the development, parameter calibration, and diagnostics of electronic control units. All tasks in this general field can be solved reliably and in a user-friendly way using CANape: Functional development of the software, test bench applications with the ASAM MCD3 interface, test drives for trials, data logging, ECU and vehicle diagnostics, and verification of object recognition algorithms with the Advanced Multimedia Option.

Sample configuration of CANape with various display elements.

CANape can also be used as a diagnostic tester.

The CDM Studio offers extensive possibilities for managing parameter sets. Saved parameter sets can be analyzed, compared, mixed and also be flashed into the ECU.

Measurement Data Acquisition

Using the measurement and calibration protocols CCP and XCP, CANape acquires ECU-internal measurement variables synchronous to ECU operation. The measurement data of the ECU's are recorded synchronous to other measurement data (from the CAN, LIN, or FlexRay bus, GPS, audio, video, or other measuring devices) and can be displayed in a variety of ways.

Features of measurement data acquisition in CANape include:

Several different window types and user-defined panels for graphic display
Virtual signals calculated online from logical relationships between real variables from diverse sources with help of internal script language or MATLAB/Simulink models
Import and export functions for measurement files
Wide variety of triggering options for targeted data logging including pre-trigger and post-trigger times (also for audio and video)
Synchronous acquisition of arrays, characteristic curves, and maps

Evaluation of Measurement Data

CANape offers a multitude of user-friendly options for editing and evaluating the measurement data of earlier measurement runs:

Study of signal responses with any desired level of detail using zoom and search functions and measurement cursors
Signals can be displayed over a time axis or in XY representation
Comments and macros may be added for offline analysis
Arithmetic evaluations using the integrated programming language and/or MATLAB/Simulink models
Use of customizable print templates

Calibration/Parameter Setting

Value displays are specially adapted to specific types of parameters. Values are either displayed alphanumerically or the user may choose graphic representation for characteristic curves and maps. User-defined panels may also be created and used to display and set parameters. The following parameter-setting functions are provided:

The user sets parameter values online in the ECU's memory or offline in CANape's "mirror memory". The offline mode allows the user to set ECU-specific parameters without being connected to the ECU, either before or after a measurement run.
Parameter setting in parallel to measurement data acquisition
Flashing of binary files and parameter sets
Flash kernels are available for many controller types
A parameter set of parameter values valid at the given measurement time can be generated from the measurement file

Database Editors

Different editors are supplied with CANape so that the user can professionally edit the various description files or view them:

Simple creation of the ECU description file in the ASAP2 Editor
Editor for viewing CAN, LIN, and FlexRay description files in DBC format
Editor for viewing LIN description files in LDF format
CANdelaStudio View for viewing CANdelaStudio diagnostic description files

Calibration Data Management (CDM Studio)

The integrated CDM Studio manages parameter sets. A parameter set contains the values of those parameters that are specified in the ECU description file, whereby CANape offers the following functionality:

Parameter sets are saved in symbolic, address-independent parameter set files. This ensures that they can be processed independently of the ECU program level at which they were created.
Visualization and editing of the contents of parameter sets
Multiple parameter sets may be opened simultaneously so that they may be compared, summarized or edited.
Flashing of parameter sets
Support of the XML-based PaCo format, so that supplemental meta-information can be saved for each parameter value, e.g. author, date, and comments

Server-based Calibration Data Management with eASEE.cdm

The data accumulating during calibration (program and data contents, description files, documentation) can be managed in a process-conformant manner in a database with eASEE Calibration Data Management, a standalone software tool, and they can be saved for reuse across projects. The increasing complexity of calibration projects can be mastered by managing all data objects in variants, versions, and configurations.

Diagnostics

The "Diagnostic Feature Set" permits symbolic access to diagnostic functions and data. The diagnostic description file is created with CANdelaStudio . If there is no special diagnostic description file, the generic files supplied for UDS and KWP2000 also enable symbolic access to functions and raw data. As a diagnostic tester CANape offers the following functions:

Selection, parameterization, and execution of diagnostic functions on the diagnostic console, e.g. reading out and displaying ECU identification
Window for displaying and editing the error memory; symbolic display of DTC's and environmental data
Detailed and symbolic representation of the executed diagnostic functions and their results in a Trace Window
Visualization of the chronological flow of diagnostic functions and diagnostic communication between ECU's
Scripts for automating diagnostic sequences
