Dummy head for automotive engineering on show at SENSOR + TEST

5th May 2017
Alice Matthews

New hardware and software products for research, test and development requirements in the automotive industry will be presented by IPETRONIK at the SENSOR + TEST 2017 exhibition (Nuremberg, 30th May to 1st June 2017) in hall 1, stand 1-240. The spectrum ranges from an innovative dummy head for climatic/acoustic engineering to a specially developed measuring system for safe HV measurement in electric and hybrid vehicles through to the ETH gateway CLFD box, a highly compact and multi-channel, modular interface module.

With ARCOS 1.5, IPETRONIK is also exhibiting a modular high-performance data logger system for fleet trials.

IPEacoustic head – climatic/acoustic engineering for vehicles
With the development of the IPEacoustic head, IPETRONIK is further extending its expertise in the field of vehicle climatic/acoustic engineering. This innovative dummy head, which has a wedge-shaped design, features a binaural microphone arrangement for aurally compensated noise recording as well as a third microphone in an acoustically neutral measuring position. 0.5" microphones with IEPE or 200V power supply are used. The IPEacoustic head allows climatic/acoustic tests to be conducted reproducibly in the vehicle – with an identical installation position. The head provides space inside its torso for a noiseless high-performance PC for online measurement data processing with IPEmotion. The dummy head is compatible with standard acoustic measuring systems.

Solutions for e-mobility – measurements in the HV system up to 850VDC/900A
HVshunt2 is a new, specially developed measuring system for safe HV measurement in fleet trials of electric and hybrid vehicles. The recording of voltages, currents and temperatures in the HV environment of vehicle batteries is a key measurement application. With the new HVshunt2 as a further development of the established HVshunt, the measuring range for current measurement up to ±900A has been extended via a current transformer with an accuracy of ±0.2%. Thanks to the pre-assembled customer-specific cables with HV connectors, the module facilitates tool less and safe integration into the HV on-board power supply, which in turn permits short periods for the instrumentation and disassembling of the test vehicle.

Multi-channel interface module – ETH gateway CLFD
With the new ETH gateway CLFD box, the company has a highly compact and multi-channel, modular interface module, whose 16 CAN high-speed inputs, two FlexRay, eight LIN channels can be connected to the IPEmotion measurement software. This gateway gives users a significant advantage in their practical work inside the vehicle. Where in the past various dual and quad CAN or LIN interfaces had to be attached to the PC via USB, there is now only one Ethernet connection to the application laptop. This allows alternating users to quickly and easily (via an RJ45 connector) access the on-board power supply and by importing corresponding description files (e.g. OBD, DBC, Autosar, A2L, Fibex) to perform multi-channel CAN, LIN, FlexRay traffic and signal-based measurements.

ARCOS 1.5 – Modular high-performance data logger for fleet trials
Thanks to its modular concept, high processing power, data storage capacity and reliability, the ARCOS 1.5 data logger system is a suitable solution for demanding tasks in vehicle fleet trials. The modular system architecture offers users a high degree of flexibility and investment protection, since the logger can be optimally adapted according to the particular measurement task. Thanks to the modular design with plug-in modules, it is possible to extend the number of bus interfaces for CAN, CAN FD, LIN, FlexRay, ETH, MOST in line with demand. Accordingly, the system also logs large on-board power supply topologies with numerous bus networks and control units using the most important protocols such as CCP and XCP.

Test drives which for example require validation by assistance systems or aim at recording the behaviour and field of vision of the driver can be implemented using multiple USB cameras and up to eight IP cameras. The data are stored on CF cards and via SATA interfaces with a large memory depth of up to 1TB in Raid 10. The wireless communication is implemented via a plug-in module with globally operating 3G modems, GPS, Glonass and Baidu position data acquisition and modular W-LAN modules with 2.4GHz bandwidth. The absolute special feature of the ARCOS 1.5 hardware platform is the option of switching over the operating mode. For logger operation, Linux normally runs on the device as an operating system. Alternatively, it is possible – by swapping the removable storage medium – to operate the same hardware as Windows logger with the IPEmotion software as the application system for control units. With ARCOS 1.5, every customer is equipped also for catering to future measurement tasks with new requirements.

Other trade fair highlights
The Mx-STG2 6, a measurement module from the X-LINK module series with six high-speed DMS inputs up to 100kHz, and IPEmotion 2017 R1, the latest version of IPETORNIK's measurement data logging software with functions for bus analysis and vehicle acoustics in addition to the integration of CAETEC hardware, go to complete the range of products exhibited by IPETRONIK at Sensor + Test 2017.
