The German city of Stuttgart played host to the Automotive Testing Expo where over 300 companies attended to show off their new technologies in the areas of car testing, evaluation and quality control. Here are some of the highlights.
The GPS-aided gyro system Automotive Dynamic Motion Analyser (ADMA) from GeneSys has been developed to measure car dynamics and driver assistance parameters in the automotive sector.
The new generation of ADMA has an output rate of 1000 Hz, data latency of less than 1 millisecond and various CAN-Bus and Ethernet interfaces. The company says the new DELTA function enables centimetre-accurate measurements between several vehicles in real-time.
The ADMA permits measurement of motion such as acceleration, velocity, position, rotational, position angle and slip angle of the vehicle. With ADMA3.0 new functions are available. The firmware options GeneSys has created are activated via the uploading of a license code to the ADMA.
OROS Noise and Vibration Testing Systems showed its range of NVH solutions.The company designs and manufactures noise and vibration testing systems, dedicated solutions and provides associated services.
Its says its analysers are flexible enough to handle automotive NVH testing measurements in different test environments; laboratory, in-vehicle or production. From two to 32channels, the instruments can be cascaded up to 1000 channels in distributed configurations or large channel count systems.
Yokogawa launched its DL350 ScopeCorder - a compact, portable combination measuring instrument. TheYokogawaDL350 ScopeCorder can be used for capturing, displaying, recording and analysing a variety of electrical and physical parameters in industry sectors including automotive, electronics, energy, transport and mechatronics.
Like other models in Yokogawa’s ScopeCorder family, the DL350 combines features of a general-purpose oscilloscope and those of a high- performance data recorder in a single, portable instrument.
Unlike some portable measuring solutions Yokogawa says it adds high levels of precision and accuracy to field measurements, isolated inputs for measurements at high voltage levels and long-memory capabilities.
A key feature of the DL350 ScopeCorder, which is not offered by other portable instruments, is its plug-in modularity, which allows it to be configured to suit a variety of user applications. Whether carrying out straightforward high-precision voltage measurements or handling a blend of signals coming from such things as current probes, temperature sensors, gauges, accelerometers and serial buses, the DL350 can deliver, without extra boxes or cables. This flexible input capability is achieved by incorporating two slots which are populated with any of 18 different types of user-swappable input modules. This means, for example, that four isolated 16-bit voltage inputs can be measured at speeds of one Megasample/sec alongside 16 temperatures or two separate CAN or LIN buses each containing 60 signals.
DSA exhibited its new wearable SmartMDI and SmartGlasses human machine interface equipment for improved diagnostic accuracy. The company says modern cars are highly complex and can be configured individually based on customer requirements. This diversity of variants poses challenges for factory logistics and production assembly lines. The DSA SmartMDI enables direct connection of vehicles to central production data and diagnostics servers in order to carry out independent flash and coding processes.
Modern human machine interfaces (HMI), such as SmartGlasses can be used for worker guidance during assembly and diagnostics as well as quality control processes. SmartWatches, tablets and smartphones can be customised to the manufacturer’s requirements and integrated into the system.
National Instruments (NI) presented its end-to-end automotive testing software for both Advanced Driver Assistance Systems (ADAS), and powertrain and chassis systems.
NI says it developed its system to help automotive engineers navigate the future of smart, self-driving vehicles, as a bid to remove complex, costly, and time consuming traditional testing methods.
The solution can simulate and test ADAS, V2X connected technology, infotainment, powertrain, and body and chassis hardware and software as fully integrated systems rather than discreet, disparate subsystems. The software is flexible and future-proof with a breadth of I/O, system-wide timing and synchronisation capabilities, and software-first adaptability to meet automotive test demands from concept through to production.
Chronocam showed its latest vision technology for connected vehicles and devices designed to replicate the human eye. The company is developing event-based computer vision technology to address the need for visual sensing and processing in autonomous vehicles, connected devices, security and surveillance systems. The vision sensors and systems replicate the functions of the human eye, helping to address the limitations of conventional vision sensors by enabling real time sensing of the relevant dynamic scene context and acquiring only what is necessary. Chronocam’s vision solutions set a new benchmark for computer vision performance with unprecedented speed, dynamic range, sensor level video compression and power efficiency, at the same time.
