A key heat transfer fluid (HTF) in automotive applications is monoethylene glycol (MEG) mixed with water in varying ratios. At low temperatures this fluid becomes viscous. Peter Huber Kältemaschinenbau’s Unimotive range of temperature control units are specifically designed and built so that this increasing viscosity does not affect either the temperature control or the flow control. Testing encompasses safety evaluations including material flammability tests, stress and load analyses and temperature-dependent assessments. Huber’s temperature control systems, coupled with the accurate flow control of HTF, results in reliable and repeatable results. This not only enhances the overall quality and safety of automotive components but also ensures precise engineering outcomes for manufacturers.

Leading the green way

The automotive sector is a leader in technological innovation and progress. The sector is driving ever-improving efficiencies and implementing green energy solutions. Sustainability and energy conservation have been at the core of engineering design and execution at Huber since the company started in 1968. The company’s dedication to sustainability is reflected in its use of natural refrigerants in all models, with options including refrigeration systems that use CO₂ as a refrigerant with set-points as low as -45°C. Products are fabricated using high-quality, recyclable materials that promote longevity and reduce waste. It is attention to details like this that Huber believes sets it apart and demonstrates the company’s commitment to sustainable manufacturing.

CO₂-based automotive temperature control technology 

Its latest achievement in sustainable innovation, the Unimotive GL (Green Line) series, sets a new benchmark in environmentally friendly refrigeration, according to the company. Operating with CO₂, this series provides a 100% eco-friendly alternative to systems using synthetic refrigerants. Designed specifically for automotive applications, the Unimotive GL series facilitates direct operation with water-glycol solutions, offering an extensive temperature range (in the XT variant) from -45°C to 150°C.

Attaining such an elevated temperature using water/MEG as an HTF is achieved by passively and safely pressurising the HTF circuit. In the event of a power failure, the pressure is safely lowered without the use of active components.

The series supports diverse applications, including temperature simulation tests, material durability evaluations and stress/load testing for functional automotive components. Since its adoption in the refrigeration field in the 19th century, CO₂ has proven to be highly effective. With no ozone depletion potential (ODP = 0) and a minimal global warming potential (GWP = 1), it significantly reduces environmental impact. Additionally, CO₂’s large-scale natural availability eliminates energy-intensive production processes. Its non-flammable, non-toxic and chemically inert properties make it an ideal choice for sustainable engineering solutions.

For the XT variant, with temperatures reaching up to 150°C, the carbon footprint remains minimal across the lifecycle – from production to operation and beyond.

Progress and sustainability

As automotive manufacturers integrate these eco-friendly systems, they contribute to both technological progress and environmental preservation. Huber’s principles of quality, performance, reliability and repeatability are coupled seamlessly with ecological responsibility — which Huber says is a testament to the brand’s enduring legacy and forward-thinking ethos. In summary, Huber’s eco-friendly temperature control technology goes beyond machinery and metrics. It is a catalyst for reshaping the automotive landscape sustainably.

At Automotive Testing Expo 2026 in Stuttgart, Mayr Power Transmission will present its portfolio for test stand technology.

Automotive drivetrain test stand technology is evolving significantly, and shaft couplings that compensate for misalignment remain key components in these systems.

Based on the ROBA DS steel disk pack coupling, Mayr Power Transmission has introduced the ROBA DS Type 9120, a lighter aluminum version. Compared with the previous steel model, the aluminum design reduces the outside diameter by up to 10mm. Depending on the size and configuration, its mass and rotational inertia are reduced to about 40-60% of the steel version while maintaining comparable performance density.

The coupling is designed for rotational speeds of up to 32,000rpm. Its lightweight construction, low rotational inertia and high performance density provide practical operating advantages. The design balances rigidity and flexibility to minimize restoring forces within the drivetrain. In addition, a balance quality of G 2.5 at 5,000rpm supports smooth, low-vibration operation, helping to maintain high measurement accuracy throughout the speed range.

As standard, the coupling features manufacturing tolerance IT6. A nickel-plated surface, disk packs made of stainless steel and galvanized connecting screws provide comprehensive corrosion protection. Backlash-free shaft connections via shrink disk hubs or external shrink disk hubs ensure reproducible measurement results. The coupling is compatible with all common torque transducers as standard.

With its modular design, the ROBA DS 9120 can be configured with a range of connection options and components to suit different applications, from high-performance research and development test stands to end-of-line production testing.

In addition to coupling technology, the company will present its portfolio of safety brakes for test stand applications. Test stands for automotive drives frequently include vertical axes and linear movements that must be reliably secured, whether during ongoing test operation, during maintenance work or in the event of a fault.

The ROBA guidestop profiled rail brake acts directly on the moving masses of vertical axes, clamping them in position without backlash and with high rigidity. It is available in hydraulic, pneumatic and electromagnetic versions and is compatible with common linear guide systems.

The ROBA linearstop piston rod brake is designed to secure linear motion on round rods. Operating on the fail-safe principle, the brake remains engaged when de-energized and is intended for dynamic emergency braking applications. The product range includes six sizes with braking forces from 70-17,000N.

The ROBA-stop M series also provides a robust motor brake for compact protection directly at the drive motor. As a holding brake, it clamps reliably and holds the system in position; as a dynamic brake, it brings the load to a standstill in the shortest time possible.

Smart modules for intelligent monitoring

The ROBA brake-checker module provides sensorless monitoring of safety brakes while also supplying them with power.

By analyzing current and voltage signals, the module detects the brake’s switching status and can issue an early warning if the brake may no longer release reliably under existing operating conditions. This supports predictive maintenance and helps users identify critical factors such as insufficient supply voltage, improperly sized power lines, increased coil temperature or excessive air-gap wear.

When combined with the ROBA gateway module, the system can be integrated into networked environments. Brake data can be continuously accessed via ethernet and displayed on a dashboard for monitoring and analysis.

This allows anomalies in the test process to be identified early, supports planned maintenance and helps reduce unplanned downtime. The system can also be integrated into remote maintenance and monitoring platforms.

“VDA 4.1 is the result of listening closely to our customers’ needs,” said Mike Weglarz, ATI’s executive director for software products. “Engineers told us they needed greater flexibility in how they view and compare data across multiple monitors, native access to CAN and LIN bus trace data without switching tools, and smarter ways to collaborate on large MDF4 datasets across distributed teams. VDA 4.1 addresses all of this – and more.”

One of the key features is the floating and dockable workspace. Pages and tabs can be freely undocked into independent windows and repositioned across multiple monitors. Panel pages enable side-by-side views of graphs, data grids, GPS maps and CAN/LIN bus trace data simultaneously. Chain cursors link navigation across all open windows in real time, significantly improving multiscreen analysis workflows for rapid MDF4 file analysis.

VDA 4.1 introduces native display of CAN and LIN bus messages recorded within MDF4 files, complete with message filtering, a time slider and cursor synchronization with trace pages. Furthermore, engineers can now inspect raw bus traffic correlated directly with measured signals inside the single VDA 4.1 application – eliminating the need for a separate CAN analysis tool.

ATI’s new software includes a new dashboard page and live gauges. The new page type hosts circular and linear gauges, data lists and text boxes that can be locked once configured and linked to trace page cursors. VDA 4.1’s dashboard provides a quick view of different data and a professional, presentation-ready data view purpose-built for test debriefs and live review sessions.

It also comes with optional Vision Enterprise integration. VDA 4.1 integrates fully with the forthcoming optional Vision Enterprise (VE) 1.0 collaboration platform, which will provide centralized MDF4 file storage, powerful 21-criteria metadata search, folder notifications, tag/property editing and upload/download with progress tracking. Vision Enterprise is available as a separately licensed add-on and is expected to launch later this year.

In terms of performance and reliability, more than 30 targeted bug fixes address stability across calculated channels, MDF file handling, GPS visualizer with KML export, layout reapplication and ASCII export.

Vision Data Analyzer 4.1 is available as a subscription-based software license for 64-bit Windows 10 and Windows 11. Site licenses for corporate volume deployments are available on application. The soon-to-be-launched Vision Enterprise collaboration module requires a separate VE server license.

“For engineering teams already using ATI Vision data acquisition hardware, VDA 4.1 is the natural next step,” noted Peter Knivett, executive VP for commercial at ATI. “And for teams using any MDF4-compatible datalogger, VDA 4.1 offers a professional-grade analysis environment at a price point that is highly competitive with far more complex toolchains. The combination of flexible workspace, CAN/LIN trace viewing and optional future Vision enterprise collaboration makes this a compelling choice for control system development teams.”

VDA 4.1 is designed for test engineers, calibration engineers, data analysts and validation teams at OEMs, Tier 1 suppliers and engineering service providers. It supports automotive powertrain, chassis, EV/HEV and ADAS development, as well as heavy truck and bus, agricultural, marine, aerospace and off-highway applications – wherever ASAM MDF4-format test data is used.

Piezoresistive absolute pressure sensors are suitable for recording static and dynamic pressures. They have long been used in the automotive industry for engine and powertrain development, where high accuracy is required. To enable this degree of precision at elevated temperatures, the sensor needs additional cooling.

The 4017A…W set from Kistler includes the water-cooled 7547A adapter and the 4017A pressure sensor with an M8x0.75 threaded connection. The 4017A is around 25% smaller than the 4049B water-cooled sensor, making it easier to use in space-constrained engine applications. The adapter’s low mass and optimized cooling channels improve cooling efficiency, helping to extend sensor life and reliability. A welded heat shield keeps the sensor within its operating temperature range in hot environments, and the lower weight reduces sensitivity to engine vibration.

The modular design of the 4017A…W set allows the sensor and adapter to be easily replaced. For cleaning, the 4017A can be disconnected from the adapter and reattached as needed. Its oil-filled, media-separated measuring cell provides high compatibility with gaseous media, along with strong measurement accuracy and stability (≤1% FSO), supported by digital temperature compensation.

Kistler’s PiezoSmart technology enables automatic recognition of the miniature absolute pressure sensor by DS-compatible amplifiers, reducing the risk of incorrect setup and configuration. The system also uses model-based digital temperature compensation to adjust the output signal in real time according to sensor temperature, improving accuracy and response. In addition, it allows for continuous monitoring of sensor temperature.

When Hyundai Mobis required a reliable test solution to verify its Hybrid eCall system, the company selected Anritsu for its proven expertise in automotive communication testing.

As the automotive industry transitions from the conventional eCall emergency call system operating on 2G and 3G networks, where vehicles automatically contact emergency services in the event of an accident, to the next-generation (NG) eCall system using 4G networks, Hybrid eCall is crucial in bridging the gap.

Hyundai Mobis has adopted Hybrid eCall and overcome significant challenges, including acquiring test equipment, mastering the advanced 4G and 5G mobile protocols required for call initiation, and addressing the limitations of network simulation environments in the early stages of development.

Anritsu’s eCall Tester MX703330E and Signalling Tester MD8475B provided an effective solution to these challenges. By establishing a comprehensive test environment and using automated conformance testing and log analysis functions, Hyundai Mobis promptly identified the root causes of operational issues. Furthermore, sharing the test environment between the development and verification teams improved consistency, reliability and operational efficiency.

Hyundai Mobis integrates Hybrid eCall functionality into its data connectivity unit (DCU). Conformance testing is conducted to EU regulations and ETSI (European Telecommunications Standards Institute) standards to verify the system’s functionality across various network conditions as well as ensuring interoperability with public safety answering points (PSAPs).

In addition, Hyundai Mobis was required to design test scenarios, perform error analysis, prepare detailed test reports and develop technical verification documents necessary for certification. These processes were supported by Anritsu’s simulation and functional testing capabilities.

There were two primary reasons why the company selected Anritsu’s test solution.

First, it enables comprehensive Hybrid eCall testing with an all-in-one tester. Previously, separate testers were required to verify Hybrid eCall, NG eCall and eCall. By integrating Anritsu’s MX703330E software-based tester with the MD8475B hardware tester, all three types of eCall functionality can be tested using a single solution. This integration reduced initial investment requirements and operational workload, improving overall verification efficiency.

The second reason was enhanced collaboration and efficiency using the same test environment as the development team. This alignment facilitated accurate issue reproduction and streamlined root cause analysis. Additionally, Anritsu’s clear setup documentation contributed to more efficient software updates and debugging activities.

With Anritsu’s technical support, Hyundai Mobis teams gained early access to the MX703330E, MD8475B and beta firmware versions. This enabled them to verify Hybrid eCall‑related software updates prior to official release, and perform conformance testing during the development stage.

Anritsu’s test solution also helped Hyundai Mobis build expertise in 4G and 5G mobile communications and Session Initiation Protocol (SIP) signaling. Analyzing the operation of the SIP using the sequence log feature provided a practical understanding. Furthermore, the setup procedures were based on the provided manuals, and network simulations were repeatedly conducted with on-site support and phone consultations with Anritsu’s staff. With this support, the teams steadily acquired the knowledge of mobile communications required for eCall verification.

The teams also needed to simulate various network conditions. Using the handover and cell configuration features of the MX703330E and MD8475B, including signal strength control, ECL settings and service controls, they were able to effectively reproduce real-world network conditions. This enabled prompt and effective software verification.

Since implementing Anritsu’s test solution, compatibility between the DCU and the test environment has remained consistently high. The teams experienced no notable issues when integrating the product with existing hardware. The test environment was configured efficiently, and stable operation was achieved from the initial stage of deployment.

Hyundai Mobis has been able to conduct reliable, repeated testing in the laboratory, building a normal testing environment. It has also automated conformance testing and network simulations. Test scenarios were created using Anritsu’s SmartStudio Manager (SSM) MX847503A, which supports the generation of rapid and reliable test results, thereby contributing to improved development efficiency and product quality.

When issues arise, reviewing the sequence and message logs of the tester allows immediate determination of whether the problem is due to device settings or the hardware itself. This enables the verification team to provide accurate and timely feedback to the development team, reducing the time required for root cause analysis and problem resolution.

During the implementation process, Anritsu supported the teams from the program installation stage, which allowed them to establish the test environment smoothly. One unexpected issue was that the USIM card initially provided for the device was not compatible with performing the test eCalls required for functionality verification. Anritsu promptly provided a compatible USIM card, allowing the verification activities to continue without interruption. No additional compatibility issues were observed with the existing DCU verification setup.

Another challenge was the provision of a reporting tool, including testers’ logs. The initial conformance test reports could not be presented as objective evidence to certification bodies and relevant departments, necessitating further improvements. In response, Anritsu updated the reporting tool to create highly reliable reports that included logs from the MX703330E. As a result, verification results could be presented more clearly and convincingly.

Anritsu’s tester is stable and reliable, enabling the Hyundai Mobis teams to focus on analyzing hardware issues during the verification processes. On-site support and telephone and email communication from Anritsu – along with the manuals provided by Anritsu’s representatives – enabled the Hyundai Mobis teams to acquire the skills to operate the tester.

With Anritsu’s technical support, Hyundai Mobis plans to expand automation within its verification processes.

Beyond the eCall functions, the Anritsu test solution supports verification capabilities, including SMS transmission and throughput measurement. Although the details of these functions are still being finalized, Hyundai Mobis hopes to use them to increase the value of the equipment by broadening the scope of verification, enabling a more multifaceted analysis of product performance and, ultimately, contributing to the development of even higher-quality products.
