Creo Dynamics technologies are fully complementary to the audio competences of Faurecia Clarion Electronics which include smart headrests, active surfaces, tuning algorithms and digital sound enabling an immersive sound experience and personalised sound bubble.
"Creo Dynamics’s unique technologies will contribute to position Faurecia Clarion Electronics, our newly created Business Group, as a full acoustic system provider delivering optimised sound performance, personalised comfort and lower-weight. Using both active and passive solutions, we will transform the user experience inside the cockpit by providing a truly immersive sound," said Yann Brillat-Savarin, Executive Vice-President Group Strategy, Faurecia.
"The interest shown by Faurecia is a strong signal that Creo Dynamics has built up world-class capabilities. Combining our competence in automotive acoustics and Active Noise Control with Faurecia will bring unique new solutions to the market," said Magnus Titus, Faurecia CEO.
Founded in 2010 and based in Linköping, Sweden, Creo Dynamics provides innovative solutions in acoustics, fluid dynamics and smart structures to customers in various industries, primarily automotive and aerospace. Through its unique expertise in automotive acoustics and control algorithms, the company develops state-of-the-art active noise control for vehicle interiors.
At the CES Las Vegas 2019, Faurecia and Creo Dynamics demonstrated an individual noise control solution to enhance the comfort and privacy of the sound experience by creating a personalised sound bubble. This was achieved by using Creo Dynamics’s virtual microphone technology combined with Active Noise Control algorithms in the headrest’s sound system.
With its graphical, voice, touch, and gesture-based controls, EB GUIDE allows the development of customised user interfaces for different brands from a single source. The software toolkit is among the most feature-rich HMI software solutions in the industry.
"EB GUIDE provides a sophisticated HMI framework and HMI development environment for automotive series production. The 2D and especially the 3D features of EB GUIDE meet all the technological and visual requirements that Volkswagen IVI and cluster user interfaces have," said Gunnar Wegner, Head of HMI Development at Volkswagen. "One key characteristic of EB GUIDE is that it excellently fits in with the Volkswagen HMI development process. Plug-ins seamlessly integrate with Volkswagen's skinning and internationalisation process. EB's HMI toolchain is perfectly suited for multi-user editing and HMI integration in our large team of developers. Volkswagen HMI Development takes on high requirements and expectations at every level. The substantial contribution EB GUIDE helps us meet these continuously."
"EB GUIDE is the ideal HMI development platform for car makers with large project scopes, such as Volkswagen," said Martin Schleicher, Executive Vice President at Elektrobit. "Our HMI products enable Volkswagen to use and customize the many versions and variants of its operating functions across all brands. All models, animations, widgets and modules that were developed for a specific brand or model can be easily used for other brands and platforms.”
EB GUIDE helps to save time and increases the productivity of HMI development teams by consequently applying a model-based approach to the HMI development process including prototyping, specification, implementation and maintenance. Instead of developing software, HMI developers design the HMI with EB GUIDE's desktop tools and execute it with EB GUIDE's run-time components which are specifically engineered to run on automotive devices. HMI developers can focus on maximising the user experience. EB GUIDE lets them instantly test their changes on the desktop PC and quickly deploy them to the target device.
EB GUIDE is the only HMI development platform in the market that enables developers to implement intuitive graphical 2D or 3D user interfaces with voice, touch, and gesture control features. It is the result of more than 15 years of experience in HMI software development. EB GUIDE was originally developed for the automotive industry but is also used in other sectors such as mechanical engineering, automation, and medical industry.
Fields of electromagnetic interference often form where electric current flows. When the flow is powerful, in high-performance electric powertrains, for example, the strength of these fields increases, and they can disrupt the signal flow in microprocessors and transmitter-receiver systems. One proven remedy is the encasement of electric components in housings made of a conductive metal. So far, aluminum has been the main tried-and-tested material for this. But its use substantially increases the proportion of aluminum in electric vehicles.
This doesn’t just impair driving dynamics and vehicle range. Costs also rise because the tools used to produce the aluminum housings have limited durability. Due to their lack of conductivity, significantly lighter plastics have not been considered as materials so far. But experts from Freudenberg Performance Materials and Freudenberg Sealing Technologies have teamed up to develop processes that can equip plastics with conductive coatings or nonwovens. Early lab tests show excellent values for electromagnetic shielding: up to 99.999999%.
There are basically two technical approaches to achieving good shielding in the frequency range of 150 kHz to 100 MHz – a spread especially relevant to the drivetrains of electric vehicles. One of them relies on a specific effect: Electromagnetic waves striking conductive surfaces can be almost entirely deflected. A second approach is to weaken electromagnetic waves at relatively high frequencies in the interior of a material – absorption is the term used to describe this effect. Two processes developed by Freudenberg combine the two effects. The processes offer specific benefits that depend on the size of the component, among other factors.
Freudenberg Performance Materials has developed a nonwoven that is treated with a special galvanic process. It totally encases individual nonwoven fibres with a copper surface, covered by another material layer to prevent corrosion. Since these nonwovens are produced as endless metered product, the technology is especially suited for components with large surfaces produced in the preforming process. Housing covers for traction batteries are one example.
The trimmed nonwoven can then be inserted and compressed into the tool with the pre-product – which is necessary anyway. An inseparable bond is formed during the setting process. Due to the low density of the nonwoven, an extremely small quantity of the material – a mere 60 grams – is consumed per square metre. That is less than the corresponding weight of normal printer paper. Combined with a lighter-weight plastic carrier material, the result is weight savings of up to one-third compared to aluminum housings. This represents about a 5-kilogram reduction in the weight of a battery housing cover.
For the shielding of fairly small components, Freudenberg Sealing Technologies has developed coatings that deflect electromagnetic waves from their surfaces. The plastic component is coated with an aqueous dispersion whose plastic matrix contains filler offering a high level of electric conductivity. One alternative is to apply the dispersion to a plastic film, which is in turn integrated into the injection molding tool. In this process, the highly conductive coating lies inside, so it is well protected from mechanical damage.
Long-term tests on material samples show that such coatings display very good aging behaviour even at 120°C and completely meet the requirements of the LV 124-2 test standard. The standard sets industry-wide testing processes and boundary values for electrical components permitted for use in cars. The protective coating, the plastic housing and its seal create a unit whose parts are ideally coordinated with one another. Freudenberg Sealing Technologies offers these solutions under the phrase “Seal & Shield.”
Whatever process is used, neither the coating nor the use of the nonwoven impairs the mechanical properties of the plastic component. This is crucial where the vehicle’s electrical components such as motors or batteries are installed in a way that they can be damaged in an accident. But the acoustic and vibration-related behaviours of a component are determined exclusively by the easily calculable properties of the plastic.
In some applications, it is important for the absorption to account for the lion’s share of electromagnetic shielding. This especially applies to the housings for radar sensors that operate in the 77-gigahertz frequency range. If the housing surface were to deflect radar waves, the result could be signal distortion. Freudenberg Sealing Technologies has developed a composite material that can be processed using injection molding and, based on early measurements, exhibits much higher absorption rates than commercially available plastics.
It is not just Freudenberg Performance Materials and Freudenberg Sealing Technologies that are teaming up to develop lightweight materials that offer electromagnetic shielding. The two sister companies collaborate with Freudenberg Technology Innovation, the Freudenberg Group’s main research unit, on the selection of appropriate test procedures and on material development.
"Demand for cabin and occupant monitoring are accelerating growth in the global automotive image sensor market," said Thilo Rausch, Product Marketing Manager at OmniVision. "Our new OV2778 image sensor enables these applications in mainstream vehicles by providing the best value with high sensitivity across all lighting conditions."
The OV2778 is built on OmniVision's 2.8-micron OmniBSI-2 Deep Well pixel technology, which delivers a 16-bit linear output from a single exposure with best-in-class low-light sensitivity. With the second exposure, the dynamic range increases to 120dB, which minimises motion artifacts. With leading low-light performance, this sensor is ideally suited for in-cabin applications. Additionally, with an integrated RGB-IR, 4x4 pattern color filter and external frame synchronisation capability, the OV2778 yields top performance across varying lighting conditions.
This image sensor is AEC-Q100 Grade 2 certified for automotive applications. It also benefits from the large installed base of its predecessor, enabling the OV2778 to be easily integrated into existing automotive platforms.
OV2778 samples are available now, along with a plug-and-play automotive reference design system that can be connected to any vehicle for rapid development. This image sensor will be demonstrated at the Auto Shanghai trade show.
In production, these images are powerful tools in numerous use cases in training and qualification, planning of workstations at the assembly line, or quality control. In all applications, the technology keeps modestly in the background. No extensive IT expertise is required to use these applications efficiently.
Thanks to VR, planners in construction, plant engineering, logistics and assembly can now assess new production areas completely virtually together with production staff and test new processes in 3D. This type of planning is based on digitised factory data available in 3D.
For several years now, the BMW Group has been digitally capturing its actual plant structures with special 3D scanners and high-resolution cameras to an accuracy of just a few millimetres. This provides a three-dimensional image, or scatter plot, of production areas and does away with the complex, digital reconstruction of structures and manual on-site recording. When planning future workstations or entire assembly halls, the BMW Group’s business units now combine existing data with a virtual library of shelves, mesh boxes, small load carriers and around 50 other particularly common operating resources.
At its Production Academy, the BMW Group trains managers, production planners, process leaders and quality specialists on the principles of lean production. As key communicators, training participants then pass on this knowledge on the shop floor. For about 18 months now, AR goggles have been used in training sessions for engine assembly units.
Visualisations guide participants through all process steps and give specific information. Participants can work at their own pace, determining the speed of the training via voice control. Three people can go through the AR training at the same time, after receiving quick guidelines from a trainer who supervises their progress.
Previously, a trainer had to work with one person at a time, while with the new system this number has increased to three. Surveys among participants and evaluations of their learning success have shown that there are no differences in quality compared to conventional training courses.
The engine assembly training can also be easily adapted to other screw joint processes – thanks to an authoring tool developed by the BMW Group for designing training programs. Setting up a new training program with this software is quick and easy: To complement real images, the relevant points of interest are determined at a regular PC and then set with the aid of AR goggles, and that’s all. In the course of 2019, this software will be made available to all interested staff via the self-service portal.
Checking a complex part weighing up to 25 tons, such as a press tool for the production of body parts, can take a lot of time. But speed is an issue: If the inspection takes place at Goods Receipt, an incompletely delivered tool can be returned even before being transferred to an interim storage site.
The process is simple: Staff at the Munich location of the BMW Group Toolmaking and Plant Engineering unit mount a standard tablet on a tripod. The built-in camera of the tablet produces an image of the tool. Then, an AR application superimposes this image with the CAD construction data of the tool ordered. Based on an average of 50 criteria, such as drill holes and other clear surface features, the staff can see whether all production specifications have been implemented.
In the event of minor deviations, it may make sense to rework the tool on site – because the early detection of the issue leaves sufficient time before the tool has to be sent to the assembly area for completion with further components.
Later this year, the toolmaking unit in Munich will completely convert the incoming goods inspection of delivered tools to the AR application. The tedious comparison between CAD data on the screen and the actual tool will then be a thing of the past.
The BMW Group also applies target/actual comparisons at its Munich plant. Using an AR application, specialists use pre-series vehicles to check the maturity of construction concepts and the correct installation position of components in these vehicles. The system makes it possible, for instance, to determine whether a side wall (fender) has the right dimensions, an exhaust system is installed in the correct position, or all the necessary parts have been mounted.
Visualisation of relevant CAD data only takes a few seconds. Data from several parts can be combined as desired and superimposed on the camera image of the tablet PC. An algorithm calculates the best fit, i.e. the ideal position of individual components in relation to each other, and highlights important design features. The application developed jointly with the Fraunhofer Institute for Computer Graphics Research provides important information as to whether any adjustments, be it in vehicle design or manufacturing processes, are necessary before a model can go into series production.
The future Singapore Additive Manufacturing TechCenter Hub, supported by the Singapore Economic Development Board (EDB), will serve as the regional hub for the company’s Mülheim TechCentre and aims to unlock the potential of additive manufacturing, also known as 3D printing, for customers in Singapore and across Asia Pacific. thyssenkrupp first launched a dedicated TechCenter for additive manufacturing in Mülheim an der Ruhr, Germany in 2017, with capabilities to deliver the full spectrum of the additive manufacturing value chain.
“thyssenkrupp has always been at the forefront when it comes to innovation in engineering,” said Dr. Donatus Kaufmann, member of the Executive Board of thyssenkrupp AG and responsible for Technology and Innovation. “We have made great strides with our Additive Manufacturing TechCentre in Germany. Establishing a hub in Singapore now reflects our commitment to bring our transformative innovations closer to the Asia Pacific region to meet our customers’ needs.”
Dr. Kaufmann also added that the Singapore Hub not only strengthens thyssenkrupp’s presence and operations in Singapore and Asia Pacific, but also “gives us the opportunity to benefit from Singapore’s innovation ecosystem and to serve new customers in the Asia Pacific region.”
Additive manufacturing in Asia Pacific is expected to grow to more than $5.5 billion by 2025 and Singapore is certainly fertile ground for the innovation to grow. The Research, Innovation and Enterprise 2020 or RIE2020 Plan of Singapore, which is the country’s roadmap for research and development, includes additive manufacturing as one of the key enablers that will support the country’s push for leadership in advanced manufacturing and engineering.
thyssenkrupp's TechCentre Hub in Singapore, together with the existing TechCentre in Germany, will focus on innovations around additive manufacturing solutions in metal and plastic technologies for customers in automotive, capital goods, chemical, mining and other heavy industries. It will provide a complete range of additive manufacturing services from part identification diagnostics, project delivery to training and capability building. The TechCentre Hub will also host additive manufacturing engineers who will work together with their colleagues in Germany to develop various products and solutions leveraging on this innovation.
In the Autopilot settings menu, a driver can press the Customise Navigate on Autopilot button which will now display three additional settings – Enable at Start of Every Trip, Require Lane Change Confirmation, and Lane Change Notification.
Through the Enable at Start of Every Trip setting, Navigate on Autopilot can be set to automatically turn on each time a driver enters a navigation route. Once enabled, anytime a driver is on a highway and uses Autopilot with a location plugged into the navigation bar, the feature will be on by default.
If a driver selects ‘No’ to Require Lane Change Confirmation, lane changes will happen automatically, without requiring a driver to confirm them first. Drivers can elect to get notified about an upcoming lane change by receiving an audible chime as well as a default visual prompt. Additionally, all cars made after August 2017 will also have the option to have their steering wheel vibrate for the alert as well.
Each of these notifications are meant to provide drivers with the opportunity to check their surroundings and determine whether they want to cancel the lane change before it’s made. Cancellations can be made by moving the car’s turn signal or by pressing the lane change cancellation pop-up notification on the car’s touchscreen. This feature does not make a car autonomous, and lane changes will only be made when a driver’s hands are detected on the wheel. As has always been the case, until truly driverless cars are validated and approved by regulators, drivers are responsible for and must remain in control of their car at all times.
Through Tesla’s internal testing and Early Access Programme, more than half a million miles have already been driven with the lane change confirmation turned off. The automaker consistently reviews data from instances when drivers took over while the feature has been in use, and has found that when used properly both versions of Navigate on Autopilot offer comparable levels of safety. The company has also heard overwhelmingly from drivers in the Early Access Programme that they like using the feature for road trips and during their daily commutes.
These new settings will be available to customers who have purchased Enhanced Autopilot or Full Self-Driving Capability. They will begin to roll out via an over-the-air software update to customers in the US, and will be introduced in other markets in the future pending validation and regulatory approval.
The expert team at the startup/analysis centre has already firmly established polymer 3D printing in the craft-scale R8 factory at the Bölllinger Höfe. They develop ideas for new or optimised tools in close collaboration with their colleagues on the production line.
The team under project manager Waldemar Hirsch design the tools on site and print them on the 3D printer. During a one-week workshop last December, the expert team trialled the use of this fast, convenient service for volume production in the factory. They identified several hundred applications where printed auxiliary tools offer substantial savings potential.
“By establishing a separate specialist department for 3D printing, we are professionalising this already successful project. Even more employees will be able to benefit from the experienced expert team and the custom auxiliary tools in the future,” said Helmut Stettner, the Neckarsulm plant manager.
Audi is also using the project to actively drive cultural change. The employees on the production line are directly involved in the development process for the 3D-printed tools.
Hirsch gives top priority to focussing on the employees and their needs. “When designing a prototype, it is very important to us that we fulfill our colleagues’ wishes exactly,” he said. “Our goal is to provide our Audi colleagues the 3D-printed tool as quickly as possible, thus supporting them in their daily work.”
The process is another building block in the company’s digital transformation. For Audi it marks an important step in the evolution of production into a modern smart factory. The use of the futuristic technology enhances flexibility and efficiency in addition to enabling the products to be customised as suggested by the employees.
“The decision to establish the new department supports the creation of a cross-site network. Ultimately the entire Volkswagen Group will benefit from the expertise in Neckarsulm,” said Stettner.
