EU-recognized Bosch “eco-innovation” uses navigation data to achieve benefits that can for the first time be used as credits to offset CO2 fleet emissions
Bosch system proactively manages the battery charge state in hybrid vehicles and facilitates optimized energy recovery
Cash-value benefits for vehicle fleets
Bosch has now received EU approval for a system for hybrid vehicles that the EU considers “an innovative technology for reducing CO2 emissions”. The system uses navigation data to adjust the vehicle's battery charge state. The technology that the EU Commission furthermore described as an “eco-innovation” thus provides a benefit that can be used as a credit to offset the passenger car fleet emissions of the respective automobile manufacturer.
Hybrid vehicles, in contrast to conventional vehicles, are able to recuperate some energy during braking by using their electric motor as a generator to charge the battery. Since a sufficient amount of energy must always be kept available in the battery for electrical driving, it is not always possible to fully exploit the potential of braking energy recuperation in hybrid vehicles. This is particularly the case on long downhill stretches of road or when the brakes are applied very frequently. In such situations, the battery becomes “too full” too soon if it has not been sufficiently depleted beforehand.
Navigation data optimizes the aggregate energy consumption Using topographical navigation data such as uphill and downhill gradients and curve radii, the innovative Bosch system is able to determine which sections of the route are suitable for recovering braking energy. A long time before the vehicle reaches these sections, the system adjusts the level of battery charge based on the navigation data so that optimum recuperation will be possible. “With the intelligent link between extended navigation data and special powertrain control algorithms, we ensure that both fuel consumption and CO2 emissions are reduced significantly,” says Dr. Michael Bolle, Executive Vice President Engineering of the Bosch Car Multimedia division.
Within the scope of EU certification, this Bosch development is considered a CO2-reducing measure. By linking the navigation system to the hybrid vehicle's driving strategy, the Bosch system provides a per-vehicle benefit that can be used as a credit to offset the fleet emissions of the respective carmaker – it can therefore also avert penalties that would be imposed when the legally prescribed average CO2 emission limit is exceeded.
Investment in traffic infrastructure a requirement for future mobility
Technical potential of traffic management not exploited
Exploratory field tests of solutions and concepts in Germany
Berlin – Franz Fehrenbach, the chairman of the supervisory board of Robert Bosch GmbH, is calling for more investment in an intelligent infrastructure to facilitate future mobility. “The transportation of the future must be realized in Germany first. To enable this, we need more investment – and more sensible investment – in our mobility infrastructure,” Fehrenbach said at the 30th German Logistics Congress in Berlin. Above all, Fehrenbach sees the country lagging behind considerably in the area of traffic infrastructure. Catching up will involve not only bridge repairs and the construction of more freeways, he said. It will also require investments in infrastructure to be oriented toward the fundamental trends in mobility. According to him, electrification, automation, and connectivity are placing new demands on infrastructure. One of these is efficient traffic management. A first step toward this could be made by implementing a road toll, he explained. “The potential offered by traffic management as well as the other technical possibilities of a networked traffic infrastructure are currently still being ignored in public debate,” Fehrenbach said. Instead, the argument is centering on the question of scope and how the revenue generated by a vignette-based road toll system should be used.
Germany: exploit opportunities offered by trend towards connectivity Fehrenbach believes that the global trend toward digital connectivity will also fundamentally transform mobility – and with it, traffic. “We must make Germany a hub for this technology. In order to do this, we need the necessary infrastructure,” he said. The shape of future traffic flow – whether of people or goods – is still to some extent the subject of research. However, the mobility trends of the future are already clear. “Achieving electrified, automated, and connected mobility will only be possible if we create the necessary technological conditions and framework in advance,” Fehrenbach continued. This includes, for example, interfaces between renewable energy and alternative powertrains, telematics services, and the efficient management of traffic flows. “With a modern, integrated system, Germany could further extend its expertise in the realm of intelligent traffic management.” The limited discussion surrounding the topic of a road toll is thus disappointing, he said.
Mobility concepts are an export opportunity In particular, the megacities that are emerging worldwide need new mobility concepts. “Intelligent, resource-conserving, and hence sustainable mobility could be the next big export opportunity for Germany,” Fehrenbach said. However, Germany has up to now been lacking the necessary infrastructure to “field test” new concepts and solutions, he argued. “The role of infrastructure as a vehicle of innovation has been fundamentally underestimated. This has been demonstrated in the discussions about investment priorities and their financing.”
Competition: engine of progress rather than threat to it Fehrenbach currently sees considerable potential for efficiency in many of Germany’s markets and sectors. He believes that in some areas, a lack of competition, state intervention, and over-regulation could be leading to a lack of transparency, inefficiency, and undesirable market developments. “Competition is perceived as a threat rather than as an engine of progress,” Fehrenbach emphasized. Only by strengthening the principles of Germany’s social market economy will the country’s future as an industrial location be assured. “Competition as a core element of a social market economy guarantees progress, growth, and thus prosperity.”
Shaping the future: no letting up now With respect to the coalition negotiations between the Christian Democrats and the Social Democrats, Fehrenbach pointed to the great need for reform which continues to exist in Germany. He warned against letting Germany’s momentarily strong economy divert attention away from the real challenges. “If we let up on shaping the future now, we will fall behind globally.”

Managing the future information flood economically and safely
Efficient human-machine interface is key to progress
Close link between driver, coach fleet operator and client for greater efficiency and speed
Greater efficiency, more traffic, more information, new technical functions – a development with which freight forwarders, coach operators and their drivers are confronted more and more frequently. This calls for new technical solutions that commercial vehicle manufacturers must already explore today to be able to offer them to their customers tomorrow. As a leading global supplier of automotive technology, Bosch has applied its indepth expertise and mapped out a vision for the instrumentation of the driver workplace of the future – a vision that has become a reality people can experience, touch, and try out.
The model on display at the Kortrijk Busworld shows how the technical innovations interact with information management designed by Bosch in a futuristic setup. "Our visitors will experience a realistic view of how a driver can manage the great variety of information, communication and new functions in the workplace," says Theo Drijfhout, Vice President of the Business Unit for Professional Systems at Bosch Car Multimedia. "Above all, we want to make things easier for the driver." This is what the Bosch experts call "Driving Convenience". A crucial element in this is the instrument cluster, working in concert with a central control unit and all its peripheral systems.
Variety managed by electronics The commercial vehicle of the future will feature a wide array of information, communication options and functions. For fleet owners and drivers alike, this will offer greater economy, improved flexibility, enhanced safety and more convenient functions. What is more, the information and communication variety will grow significantly by the end of the decade: This will be driven by features including the integration of such assistance functions as driver drowsiness detection, driving lane detection and emergency braking systems, along with the integration of smartphones, new telematics services, software apps and even region- and OEM-specific functions.
Structured vehicle operation That is why the developers have placed a strong focus on structured information and communication in the Bosch model. In this mock-up, the various functional units are networked via a central control unit and can thus communicate with one another and with the driver. At the same time, the central head unit also provides for communication to the outside world – into the cell phone network, through internet access or via Car-to-X communication with the infrastructure and/or other vehicles.
An interactive instrument panel in the driver's range of activity To make this great variety of information a real driver benefit, however, it must be properly organized, clearly arranged and easy to use. The displays on the dashboard are focused on a large, freely programmable instrument cluster located directly within the driver's field of vision. It includes traditional round instruments, functional displays along with graphics for route planning or video sequences, e.g. from a reversing camera or a night vision system. The information offer displayed is flexibly adapted to each driving situation – important information appears large in the foreground of the instrument cluster, less important information is displayed smaller in the background, while user functions and such secondary information as route descriptions appear on the central display. This is where the driver can access the desired functions via customized user interfaces.
Connected systems Another element in the new system is based on smartphone integration. In addition to its original functions for mobile telephony and internet communication, the phone also controls a number of individual functions. When the central head unit detects the smartphone, it automatically activates the personal adjustments of the seat position, outside rearview mirrors and personal radio station preferences.
Another function very important for the driver is connected route planning. The fleet control center sends out the daily route with information on all intermediate stops via wireless communication. During the trip, the route is automatically adapted to any changes in traffic conditions and delays that occur are reported back. Because the system is connected with the digital tachograph, it knows when the driver has to take a break as specified by law. Working together with the navigation system, this new system is also able to recommend attractive restaurants to the driver and can even automatically reserve a parking space for the overnight stay.
The coach cabin of the future In our increasingly networked multimedia society, future infotainment in coaches will also provide access to individual information offers in addition to the centrally managed entertainment program. Today, many passengers already bring their own tablets or smartphones along with them. Thus, in order to provide total travel enjoyment, it’s important to make it possible for passengers to use their own devices and to provide them with direct internet access as well as local content on the vehicle server using dedicated server and router solutions. This new trend is known as "bring your own device".
Using such vehicle servers, the coach operator can offer the passengers films, electronic magazines or interactive games and photos from the last stop, either on individual tablets or via the cabin monitors. Just like a tour guide, the driver can manage the different entertainment functions centrally and have safety information displayed right at the beginning of the trip, control the audio and video contents, allocate access privileges to individual passengers and provide access to the internet. Once these settings have been made before the trip begins, the driver can then concentrate completely on the most important task: safe driving. As a result, the Bosch model study is an enlightening and inspiring look at the future of mobility and communication.
Integration of infotainment devices thanks to simple Plug and Play
At Busworld 2013, Bosch will present a new Multimedia Coach System with a special focus on safety and connectivity
Contemporary infotainment for travel coaches and minibuses plays an increasingly important role for vehicle fleet operators. In this context, the systems and components used for information and entertainment are specially designed to meet the needs of the coach industry. Nowadays, this includes interfaces for connectivity and data exchange as well as individually developed audio, video and navigation systems and on-board monitors made for use in coaches. This promises both entertainment and greater convenience – for an unrivaled multimedia experience and first-class travel enjoyment.
First-class multimedia navigation system for coaches For the first time at Busworld 2013 in Kortrijk, Bosch will feature a prototype of their latest Multimedia Coach System, a multimedia and navigation system for infotainment in luxury-class coaches with a head unit that is easily and intuitively operated via touchscreen.
In addition to Bluetooth connectivity for safe phone use and audio streaming, the newly designed system is equipped with a twin tuner, an integrated MP3- and WMA-compatible CD drive and AUX and USB slots to complete the range of available audio sources. It also includes the top-notch CAD 12 CAV cabin control unit, which – in addition to a DVD drive specially developed for the automotive environment and its own radio tuner – also offers further front panel connections for best passenger entertainment. The Multimedia Coach System’s navigation map appears on the cabin monitors so that passengers can track the route and see additional information along the way. It is also possible to display different camera views. In this case, the driver can see the back-up camera or the door monitor on his screen, for example, while the passengers can watch videos or so-called scenic views as an alternative to the navigation map.
In addition to a microphone for hands-free telephone use, it is possible to connect up to three more microphones, including a new Bosch wireless microphone. As another component in the new system network, the CPA amplifier ensures a rich sound experience in the passenger cabin. And finally, a DVB-T tuner, a DVD changer or a DAB+ box for digital radio reception can also be added optionally to the system.
Coach Communication Center for the EvoBus Group To equip the coaches of the EvoBus Group, Bosch has developed a multimedia unit with a multi-channel audio/video distribution system and a 24-volt radio-navigation unit. The system includes a digital twin tuner for crystal-clear AM/FM radio reception and features a USB port on the back as well as an additional video input to accommodate the connection of an external video camera, for example.
The Coach Communication Center’s commercial-vehicle-specific navigation also takes legal and physical limitations into account when selecting the route. To do so, different attributes of the coach, such as its height and width, for example, are compared with the information on the height of underpasses or the width of winding roads stored in the map data. This makes sure that coaches will not be routed through small villages with very narrow streets and saves the driver from having to make complicated U-turns.
New Classic Line components for minibuses and coaches Bosch offers a new series of different components from its renowned Clas-sic Line to meet the differing infotainment system needs of minibuses, city buses and coaches. The four different units have been specially designed to withstand the constraints and severe conditions of professional use in commercial vehicles. The MR12 bus radio, specially designed for use in minibuses, is a 12-V device with an integrated tuner and all the other popular options to provide the convenient hook-up of CE components via inputs on the front panel. The more sophisticated CAD12 offers a maximum in terms of CE connectivity, which translates as the largest feature range currently available on the market. It has been developed as an integrated high-end audio system for minibuses and is also equipped with a DVD drive specially developed for the automotive environment that can stand up to the more stringent requirements of use in commercial vehicles.
In a nutshell: At the Kortrijk show, Bosch will present a complete range of audio, video and navigation devices for best communications in minibuses, long-distance and luxury coaches alike. This includes comprehensive multimedia solutions as well as components and systems specially designed for use in coaches with separate sound zones for the driver and the passengers.
