ECU Calibration with CANape

Calibration/Parameter Setting

You can conveniently visualize and modify the various types of parameters in the calibration windows

Representation in parameter setting is either alphanumeric or graphic. User-configurable panels give the user a customized interface for displaying and calibrating characteristic parameters. The following functionality is offered in parameter setting/calibration:

• You can set parameter values either online in the ECU’s memory or offline in the cache of CANape. The Offline mode lets you process ECU parameters before or after measurement without requiring a connection to the ECU.
• Parameter calibration in parallel to measurement data acquisition
• All of an ECU’s parameters can be calibrated in a single window, the Parameter Explorer
• Structures with parameters can be viewed in their entirety in the Parameter Explorer
• Generation of a parameter set based on a specific time point in the measurement file
• Merging of parameter sets to make new version levels and feed the data back into software development via C, H or MATLAB files
• Parameter set files are managed in CDM Studio
• Parameter set files can be loaded, visualized and edited in calibration windows. This also enables batch operations on parameter set files.

Features of measurement data acquisition and visualization in CANape include:

• Various window types and user-definable panels for graphic representation

The VX1000 System is a modular solution with a data throughput of more than 100 MByte/s for measurement and calibration tasks. It can be used in the vehicle, on test benches or in the laboratory. To achieve maximum data throughput with minimal effects on ECU execution times, data is accessed via microcontroller-specific data trace and debug interfaces.

By using the standardized XCP on Ethernet protocol, in addition to interfacing with CANape you can interface to other measurement and calibration tools as well. Depending on the controller used, a measurement may have practically no effect on the controller.

CANape records measured data fully automatically as a stand-alone data logger. The tool acquires internal ECU data synchronous to analog measured data and bus data with the help of prepared measurement configurations.

Data logging made easy

Data loggers are autonomously operating, robust devices that are permanently installed in the vehicle and log measured data over a longer period of study. In combination with a conventional industrial PC on the market, CANape meets all of the preconditions required for use as a data logger:

• Time-synchronous signal logging from a wide variety of sources: ECUs, communication buses, measurement sensors, video, audio and GPS.

• Start of a preconfigured measurement without requiring user interaction.

• Fault-tolerant measurement: if errors occur, measured data acquisition continues or is reset, e.g. in case communication is interrupted.

• You can use trigger conditions to reduce the volume of saved data and start (diagnostic) scripts such as fault memory reports.

• Recording of audio comments during measurement: the driver's voice recorded with a microphone supplies important auxiliary information on the specific driving situation for analysis, and lets the driver keep both hands on the steering wheel.

CANape supports among other things:

• Many common high-resolution radar and video sensors
• LIDAR sensor components such as IBEO HAD, Quanergy, Velodyne
• µEye-cameras from the company IDS Imaging Development Systems as reference camera
• Other cameras with a DirectX driver are also supported
• ADMA gyro system for vehicle dynamics testing from GeneSys Elektronik
• NMEA-compatible GPS receiver

An open interface is available for integrating other systems: the DAIO (Digital/Analog IO) interface for high-performance analog measurement solutions. Users can create the drivers needed for this themselves. In development, Vector can support you with sample programs, a driver generator and other services.

Measuring and calibrating per ASAM MCD3

CANape's automation interface offers functions that enable symbolic access to bus and ECU data. A positive effect is the significant time and cost savings for potential application programs. The functionality of the automation interface is organized into the following areas:

• Setting up devices: all bus and ECU interfaces supported by CANape are available via the automation interface (CAN, LIN, FlexRay, Diagnostics, CCP and XCP)
• Measuring: supported are functions for setting up the measurement configuration, starting and stopping the acquisition process and for accepting the measured data
• Reading and calibrating parameter values
• Diagnostics: setting input parameters, executing diagnostic functions, polling output parameter values, reading fault memory
• Executing scripts

The typical use case for the automation interface is test benches. CANape supports the ASAM interfaces ASAP3 and ASAM MCD 3MC as well as a problem-oriented C-API and a user-friendly, high-performance COM interface. Access to diagnostic data is also via an easy to use interface, which reduces the complexity of a MCD3-D interface to just a few functions.

Overview of your advantages

• CANape's universal interface gives a client application access to key vehicle bus systems and protocols.

Visualize and Parameterize Simulink Models Easily and Efficiently

Conveniently measure and calibrate model parameters. CANape provides access to signals of the Simulink model via XCP on Ethernet and the Simulink XCP Server.

CANape provides you with mature functions for visualizing measured data from various sources – synchronously and with time precision. Option "Simulink XCP Server" lets you link CANape to models in Simulink and use CANape as a parameterization and visualization user interface for Simulink models. Parameter changes are easily made in CANape and transferred to the model. At the model’s runtime, Simulink sends measured data from the model to CANape via the XCP on Ethernet protocol. You access parameters in Simulink exactly as though the application were running in an ECU. Simulink models are computed slower or faster than in real time (dependent on their complexity and processing power). After the computation cycle, you can analyze the data in CANape, adjust model parameters in CANape and then start the next computation cycle.

Overview of Advantages

• Easily visualize signals and parameterize calibration parameters from Simulink models in CANape
• Parameterize your Simulink model (including integrated binary components such as DLLs) from CANape and stimulate it with real generated measured data as an input vector
• Model instrumentation is not needed for measurement or parameterization
• CANape is a tool you can use over the entire ECU development process. This reduces the number of tools you need, software maintenance costs, training requirements, etc.

Application Areas

In the context of model-based software development, functions of the application are checked in an iterative process; the model is executed iteratively in Simulink from MathWorks. The Simulink XCP Server offers all function and software developers a convenient tool for managing parameters and efficiently measuring signals from the Simulink model without instrumentation. The CANape configuration used here can be reused in a later development phase.
