Reliably Solving Complex Measurement TasksReliably Solving Complex Measurement Tasks with vMeasure exp
vMeasure exp is a flexible measurement software solution that provides you with efficient support in the laboratory, at the test stand, during test drives and endurance tests. With vMeasure exp, you can conveniently record physical values, internal ECU signals as well as signals sent via the vehicle bus. To provide an informative interpretation of the recorded data, the position data (GPS) and video data of the route traveled are also required. Typical tasks of the measurement engineer include measuring OBD signals to ascertain the status of the control unit.
With vMeasure exp, you can record all of this data simultaneously and efficiently. In just a few clicks, you create the measurement configuration, set up the measurement windows and get started with the actual measurement tasks. To make it easy to set up the measurement, configuration tools for the hardware of third-party manufacturers, such as CSMconfig by CSM, are integrated in vMeasure exp. For flexible data recording, use the multi-recorder concept with comprehensive trigger options as well as pre-trigger and post-trigger times.
Advantages
- Time-synchronous acquisition of physical values, ECU-internal data, video, GPS as well as bus data
- Practically no limitations in executing a measurement task, due to the high measurement data throughput.
- Complex calculations can even be performed during the measurement, regardless of the sampling rates of the input signals. This simplifies the analysis of
measurement results significantly – both during and after the measurement. - Extensive function library: the “eMobilityAnalyzer function package” enables, for example, the use of predefined formulas without requiring programming
or scripting skills - MDF files are indexed on the local workstation for fast, convenient retrieval of measurement data
- Flexible, individual storage of recorded channels by multi-recorder concept enables efficient measurements and allows you to focus on relevant signals
- Diagnostics support by measurement of OBD-II
Functions
- Intuitive configuration of signal sources to be recorded and of the bus systems to be connected
- Comfortable sharing of measurement projects
- Simple creation of formulas for virtual signals via a graphic interface, with functions from the function library, with MATLAB / Simulink, C-DLL or custom functions
- Simultaneously measure the analog physical values, the ECU, the bus systems and record the environment using
a camera and position data - Storage of measurement data in the standardized ASAM MDF4 format, even with file sizes over 4 GB
- Live view of measurement values even if there are no current measurements makes it easy to check the wiring and sensors as part of the measurement configuration
- Signal display over time in various windows, user-definable panels or in XY display
- Manual investigation of signal processes by means of zoom, search functions and measurement cursor
- Insertion of comments for off-line analysis
- Exporting of signals from measurement data along with synchronized video
- Data export to ASCII, Excel and MATLAB
- Convenient insertion of window content or entire display pages in Word and PowerPoint by means of drag & drop accelerates the documentation
Highlights Version 5.0
- Acquisition of rapidly sampled measurement signals (up to 1MHz)
- Online calculation e.g. power calculation of a threephase e-motor with 1MHz sampling frequency of voltage and current
- PTP accurate synchronization of interfaces, measurement modules of CSM and other measurement techniques with the Vector Time Synchronization Service (VTSS)
- Enhanced trigger functionality for high data rates and fast measurement signals
- New functions in the eMobilityAnalyzer library: Harmonics, Inverter Efficiency, PWM Power Analysis
eMobilityAnalyzer Function Library
The new eMobilityAnalyzer function library is the centerpiece of scalable measurement solutions in the high-voltage area. The voltage and current signals acquired decentrally by CSM measurement modules at sampling rates of up to 1 MHz can be used to calculate relevant characteristics of the powertrain, HV components and the electrical system online.
