Measurement and Vehicle Data Acquisition
The collection of physical measurement data from components, systems, and vehicles is often a critical step in the development process.
For example, these measurements verify whether components are sufficiently dimensioned or whether safety-critical mechanisms activate in a timely manner.
This requires data from a wide variety of sources to be acquired, visualized, and stored. Time synchronization and the handling of large amounts of data play a key role here.
Highlights
- Compact and robust: Durable housings and a high protection class make it possible to use the devices in road tests.
- High-voltage-safe measurement: Appropriate measurement technology for high-voltage applications ensures the safety of people and property.
- Coordinated, scalable system: A comprehensive solution consisting of hardware and software for individual requirements.
- High data rates and synchronous acquisition: Precise measurement, whether for highly dynamic voltage spikes or temperature values in the sub-decimal range.
Analog Measurement Technology
Not only digital measurement values from control units and vehicle electrical systems, but also analog measurement parameters from various sensors must be acquired and evaluated. Temperatures, current, voltages, mechanical loads, and rotational speeds are just a few examples of relevant physical values. Choose from a range of customizable measurement technologies depending on your measurement setup and specific requirements.
HV-Safe Measurement
Measure voltages and currents directly and safely on high-voltage components of the electric powertrain. For the electrification of various vehicles, testing in high-voltage environments is mandatory. Not only are parameters for efficiency and power calculation relevant, but also physical measurement values, such as those essential for the operational safety of electric vehicles. Furthermore, especially in high-voltage batteries, temperature and humidity must be measured inside precisely and in a high-voltage-safe manner.
Measurements During Road Testing
Compact design, high mechanical robustness, and an appropriate protection class are crucial for use in harsh driving test environments, as the focus is on measurement under real-world conditions. Various physical values as well as vehicle and bus signals are acquired synchronously to obtain a consistent overall picture of system behavior or component performance. At the same time, large amounts of data must be recorded without loss and stored efficiently, even at high data rates.
Test Bench Measurements
When measurements are performed on a test bench or in a laboratory, the focus is on reproducible measurement conditions and in-depth analysis. Under the prevailing conditions, measurements can be taken with high precision and under controlled circumstances. The close integration of data acquisition, visualization, and post-processing supports faster interpretation of the measurement results. The seamless integration of measurement systems into existing test bench architectures with automation and control systems is also essential for their successful use.
