“Satellite navigation was a telematics killer application that the automotive industry couldn’t exploit,” says Dave Marples, chief scientist for systems developers Technolution.
Telematics basically marry computers and (wireless) telecommunications technologies, but auto manufacturers often narrow this down to navigation systems when applied to ‘vehicle telematics’.
A big problem for automotive manufacturers is the speed of development in electronics. Systems installed in vehicles are outdated while the vehicle is still relatively young. In-vehicle systems need to be ‘updatable’ to take advantage of developments in telematics services and the infrastructure behind them.
Marples, who is also chief architect of the Global System for Telematics (GST) project, says ‘nomadic devices’ – not built into the vehicle – are one solution to this obsolescence problem. The device could be a handheld computer, or even a super satellite navigation (SatNav) system that establishes a connection with the vehicle’s computer systems.
“We came up with the term ‘nomadic device’ because we didn’t want to constrain what that device did and what it looked like,” says Marples. “In some ways, we were looking for the telematics equivalent of the DIN slot [where you insert] the car radio.”
“SatNav is a computation platform in your vehicle that is more powerful than the PC you had on your desktop five years ago,” notes Marples. The speedy development of a mass market for SatNav illustrates the potential for telematics – and the lessons for the automotive industry.
Most people already carry mobile phones and they will not want to carry two small computers – one dedicated to the car. Five years ago, companies were trying to get consumers to carry PDAs in their pockets. Instead, mobile phones have increasingly included PDA-style applications.
“The mobile phone has its own power supply, it can do things independently of the vehicle, and because it tends to be on the person, it is in the safe cell in the middle of the vehicle,” explains Marples. It would also mean that older vehicles could use eCall, the emergency call service that is activated manually by vehicle occupants or automatically via in-vehicle sensors following a crash.
The downside of the mobile phone as a nomadic device is the need for a complicated communication link between the vehicle and the phone, a link which is open to disruption. “One of the biggest discussion areas in GST was what the communication link between the nomadic device and the machine would look like,” explains Marples who is also professor of telecommunications at Sterling University, Scotland.
The EU-funded GST project ended in Spring 2007. It has helped to shape a framework – a common design language – that will enable the development of telematics applications running in vehicles from a range of manufacturers, and enable vehicles from different manufacturers to communicate or share data. But it will probably be ten years before we know GST’s long-term impact, Marples suggests.
The GST research teams looked at the development of the overall architecture for end-to-end telematics; the certification requirements of the telematics industry; payment and billing systems; and telematics’ system security.
It also coordinated three projects that looked at specific telematics applications: ‘Rescue’ (preparing the standardisation necessary to develop a fully integrated incident response chain across Europe); ‘Enhanced Floating Car Data’ (using vehicle systems as floating traffic sensors to monitor vehicle performance and congestion levels on the roads); and ‘Safety Channel’ (a cost-effective broadcast mechanisms to communicate safety information to drivers).Money matters, and so do standards
GST made one issue clear. The in-vehicle telematics systems of the future will not be devoted to single proprietary applications. While they understand the long-term need for standardisation, automakers’ desire to capture a share of the lucrative mobile communications revenues led them to develop proprietary telematics solutions. But the penny has dropped.
Automakers now recognise they will have to design systems that run multiple applications, notes Marples. “I don’t think people had really accepted this until we started GST. People paid lip service to the idea, but it is not the same thing as saying that they would do something about it.”

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
