In addition to an increasing need for safety and efficiency, the issue of environmental sustainability characterizes the modern world of mobility. Even today, cars are equipped with a variety of sensors. Smart Systems can combine the supplied data with further information and thus reduce the tendency to fail on the part of the driver. At the same time they enable optimal steering and navigation. In the future, everyone on the road will be able to communicate with other drivers (“car to x communication”).
Safety in traffic
A big help in traffic safety can be given by assistance systemsthat, for example, warn the driver of people or animals on the road in darkness or under conditions of poor visibility, since the risk of a serious accident remains much higher at night. However, these systems are still too expensive for use in the mass market and at the moment their use is limited to vehicles in the upper and luxury class.
Along with other partners in the cluster, Robert Bosch GmbH has developed far-infrared sensors that can be produced at a reasonable price and yet provide high resolution images. Here the company consistently focuses on established and lowpriced CMOS production technology (Complementary Metal Oxide Semiconductor) and the integration of micro-optical components in its sensor systems.
Mobility: resource-saving and low in emissions
Sensors such as those in diesel particle filters can clearly contribute to reducing emissions and complying with exhaust standards that are becoming stricter all the time. Sensors that measure internal cylinder pressure promise more efficiency and therefore optimal combustion methods. With their help, diesel and gasoline engines can become perceptably more economical. However, these sensors must be robust as well as reasonably priced. And that is exactly what silicon carbide technology offers and it is being further developed by the leading cluster for use in motor vehicles.
“Microsystem technology is an engine of innovation for more safety and environmental protection in automobile construction. The next step in development in the cluster of microTEC Südwest is the close coupling of this technology with the Internet of Things and Services to realize new mobility concepts.”

High resolution thermal imaging saves lives in trafficmoreclose
Along with other partners of the cluster, the Robert Bosch GmbH company has developed a platform technology for cost-efficient far-infrared image sensors. For the first time, this project addresses high volume production of competitive thermal imaging sensors. The development draws technologically on processes and functional materials with consistent CMOS production compatibility, in order to achieve function and cost goals.
Newly developed technological processes make a lower noise and low-stress construction possible on a silicon basis. The combination of microassembly techniques on a wafer level and concepts for the improvement of thermic insulation of the image elements are the building blocks for the high functionality and sensitivity of new cost-efficient far-infrared arrays. The development is suitable for high volume uses in, for example, automotive night-sight (pedestrian protection), security technology (surveillance), as well as for innovative products in industrial, processing, environmental and medical
An important contribution to environment-friendly mobilitymoreclose
The vision of a kind of mobility that goes easy on resources and produces minimal pollutants is the driving force behind the development and provision of cost-effective sensors for use under harsh environmental conditions. These should, on the one hand, enable an improved concept of combustion engines and, on the other hand, assure reliable monitoring of those parts relevant to emissions in the exhaust system.
For the pressure sensor in the engine compartment, Robert Bosch GmbH has developed assembly and packaging with a high potential for cost reduction. Functional proof of the soot particulate sensor for monitoring the diesel particulate filter has already been offered and fulfills expectations for the required sensitivity. The superior characteristics of the silicon carbide material are specifically used to produce such sensors in microsystem technology at a low cost. Silicon carbide is extremely resilient and is thus ideally suited to the rough conditions in the field of mobility.
