First series production vehicle with software control

19.12.2014

Siemens has unveiled the first electric series production vehicle with the central elec­tronics and software architecture RACE.

This technology, developed in the research project of the same name, replaces the entire control system with standard hardware and a kind of "operating system for automobiles."


Road to Digital Future: Siemens to Equip StreetScooter Electric Vehicle with Innovative Electronics and Software.

The RACE (Robust and Reliant Automotive Computing Environment for Future eCars) project aims to greatly simplify the increasingly complex electronics architecture in cars. Display panels describe how complex the electronics architecture of today's mid-range automobile is, and how it is changed in terms of failsafe data communication when the vehicle is equipped with RACE (RACE power wiring and information stubs are not included).

This is expected to massively reduce the development time for vehicles. Another advantage is that thanks to the standardized software base, additional functions can be retrofitted more easily and cheaply than before. Vehicle weight will also be reduced substantially.

Together with electric car manufacturer StreetScooter, experts at Corporate Technology, Siemens' global research unit, have equipped a series production vehicle with RACE technology. The abbreviation translates loosely as "Robust and Reliant Automotive Computing Environment for Future ears." A modern mid-range car has about 70 control devices installed in it and many meters of cable.

There are a larger number of different interfaces and software applications in every vehicle that interoperate without a common software base. Currently the parking sensor, navigation and air-conditioning system, for example, each need their own control device, which is connected to other control devices.

The complexity of this architecture, which has grown over the years, will become less and less transparent and thus hinder innovation. In vehicles with RACE technology, there is now only one central processing unit controlling all functions. These are designed with multiple redundancy for reasons of safety. Development time for new vehicles has now been reduced by up to 30 percent thanks to the new capabilities of RACE.


Technology can also be used for trains and Smart Grids
The aim is that new functions should be easy to add in the future as well, in the same way as with Plug & Play on a computer. Today, this is hardly possible. To equip a car retroactively, say with a rear view camera, requires an immense amount of time and effort for testing. The installation and integration of new hardware in the existing communication system is nearly impossible, and the goal is to make this function more easily in the future.

Thanks to RACE, tests for new functions can be integrated and performed digitally; new components will be connected to the RACE computer, for example via Ethernet. The component can be used after downloading the new software onto one of the control processors. Since functions no longer need a permanent connection to a control processor, it will be possible to install, for example, new infotainment or driving and assistance functions in the vehicle, ideally just in the form of software.

Less cable and fewer control devices will also have a positive impact on weight, and make cars less prone to faults. Electric cars in particular will profit from this because it increases their range and reduces running costs. The use of RACE is not, however, restricted to cars. The system architecture is also intended to be transferrable to multiple unit trains, smart grids or other complex systems.

Im Focus: The pyrenoid is a carbon-fixing liquid droplet

Plants and algae use the enzyme Rubisco to fix carbon dioxide, removing it from the atmosphere and converting it into biomass. Algae have figured out a way to increase the efficiency of carbon fixation. They gather most of their Rubisco into a ball-shaped microcompartment called the pyrenoid, which they flood with a high local concentration of carbon dioxide. A team of scientists at Princeton University, the Carnegie Institution for Science, Stanford University and the Max Plank Institute of Biochemistry have unravelled the mysteries of how the pyrenoid is assembled. These insights can help to engineer crops that remove more carbon dioxide from the atmosphere while producing more food.

Im Focus: Highly precise wiring in the Cerebral Cortex

Our brains house extremely complex neuronal circuits, whose detailed structures are still largely unknown. This is especially true for the so-called cerebral cortex of mammals, where among other things vision, thoughts or spatial orientation are being computed. Here the rules by which nerve cells are connected to each other are only partly understood. A team of scientists around Moritz Helmstaedter at the Frankfiurt Max Planck Institute for Brain Research and Helene Schmidt (Humboldt University in Berlin) have now discovered a surprisingly precise nerve cell connectivity pattern in the part of the cerebral cortex that is responsible for orienting the individual animal or human in space.

The researchers report online in Nature (Schmidt et al., 2017. Axonal synapse sorting in medial entorhinal cortex, DOI: 10.1038/nature24005) that synapses in...

Im Focus: Ultrafast snapshots of relaxing electrons in solids

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!

When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...

Im Focus: Quantum Sensors Decipher Magnetic Ordering in a New Semiconducting Material

For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.

Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
