“Automotive connectivity marks the start of a new era - until now, cars were isolated from their surroundings, but in the future the two will interact,” Wolf-Henning Scheider
“We are bringing the mechatronic world and the digital world together,” Wolf-Henning Scheider
20 years ago, the internet revolutionized computing. Over the next few years, it will revolutionize the car. Bosch is making cars an active part of the internet – and bringing drivers a range of benefits. “A connected car is always going to be a better car,” says Wolf-Henning Scheider, the member of the board of management of Robert Bosch GmbH with responsibility for the Automotive Group. By networking vehicles, Bosch is improving the comfort, safety, and efficiency of tomorrow's mobility. At the same time, Bosch is bringing the fascination of the digital world onto the streets of the physical world. In this, the company is pursuing three strategic objectives. First, Bosch is making the internet an intuitive in-car experience. Second, Bosch is connecting cars to the internet and creating driver assistance functions with added value. And finally, Bosch is networking cars with traffic infrastructure. “Connectivity is about more than just being able to surf the net on the open road,” says Scheider. Bosch is hard at work on all the necessary technologies and has already brought a selection of solutions to series production. In the future, we will see completely new functions emerge. For instance, in-car augmented reality will connect the virtual world with the physical world. The windshield will become the car's main display area, bringing all vehicle information as well as data on the surroundings into the driver's field of vision.
Objective 1: Making the internet part of the car Connectivity is well on the way to becoming a megatrend in the automotive industry, as digitalization changes the lives of more and more people. And cars themselves will be a factor in how digitalization spreads. This is why Bosch engineers are working on solutions that are both intuitive and sophisticated. One of them is MySpin, a system that integrates iPhones and Android smartphones fully into the vehicle, with the phone's display appearing on the vehicle's main display. This makes using apps in the vehicle much easier, safer, and more convenient.
Bosch is also bringing the internet into the car without the help of cell phones. Today's navigation systems can, for instance, find you a French or Italian restaurant. Future Bosch services will save drivers of electric vehicles the trouble of looking for charge spots by guiding them directly to the nearest available one, as well as letting drivers reserve the nearest parking space and guiding them to it.
Bosch is even connecting the powertrain to the internet. Bosch’s eHorizon system lays the groundwork by bringing together decades of systems competence in powertrains with innovative software programming. “We are bringing the mechatronic world and the digital world together,” says Scheider. Bosch has been offering eHorizon for commercial vehicles since 2012 as a way to smooth journeys out and reduce the amount of unnecessary acceleration and deceleration. For example, when this navigation software sees that the current two-kilometer downhill stretch of road leads to a built-up area, it can tell the vehicle to enter its most fuel-efficient mode or to charge the battery. This helps drivers save up to 15 percent of fuel. In the future, navigation data will be complemented by up-to-the-minute traffic data from the internet, so that vehicles can coast to a halt before they reach a traffic jam. This kind of connected navigation, where vehicles make use of data from the internet, is the future not only for trucks but also for passenger cars.
Objective 2: Making the car part of the internet But the data highway in cars is no one-way street. Vehicles will not only use information from the internet, they will also provide information to their environment. That's why Bosch is making vehicles part of the internet. “In connecting vehicles to the cloud, we see data protection as a fundamental requirement. The benefits have to far outweigh the potential risks,” says Scheider. To this end, Bosch subsidiary escrypt is developing security solutions that are tailored specifically to cars, such as standalone encryption.
Vehicles will in the future become sensors in their own right, gathering information about their surroundings and exchanging them with each other or with a server. Known as floating car data, this information is required both for highly dynamic maps and to improve vehicle safety. Whereas the driver sees no more than a bend ahead, the navigation system is already aware that just beyond it is a patch of ice or the tail end of a traffic jam. This means cars or trucks can be stopped from causing a pile-up or plowing into a line of standing traffic; the system can either warn the driver or automatically initiate a braking maneuver. “Connectivity is a building block in automation – and vice versa,” says Scheider.
There are already some applications in which vehicles communicate with the outside world. One example is the eCall, which will be mandatory in the European Union from 2015. When accidents occur, vehicles will automatically call the emergency services, with the call activated by the same sensors that trigger the airbag. This can reduce the time it takes for emergency crews to reach the scene by 50 percent in rural areas and by 40 percent in urban areas. Bosch's role goes far beyond the technology itself. The company serves as the interface between the accident on the one hand and the emergency services on the other. Bosch associates deal with the emergency calls in an operations center to ensure that information for the emergency services is quick and precise.
Quite apart from improving safety, this approach to collecting vehicle data will also help to save money – especially for companies and fleet operators. With Leaseplan, Bosch is networking vehicles to allow completely new forms of fleet analysis. The company is also driving forward solutions for preventive maintenance. For instance, engine data from diggers or wheeled loaders can be sent to a database, analyzed, and compared with a constantly growing archive of data from similar vehicles under similar stresses. This allows Bosch to predict whether, and more importantly when, an important component will reach its wear limit – so that the component can be replaced in good time. Taking the example of the digger, this would avoid downtime and save lots of money: every hour that this kind of machinery is out of action costs its operator up to 2,000 euros. In the future, this type of functionality could also feature in passenger cars. One application could be a wear indicator for engine parts. This would let drivers replace a damaged part before they suddenly end up stranded at the side of the road.
Objective 3: Making the car part of the internet of things Connecting the car to the internet is something that goes far beyond even these applications. “Automotive connectivity marks the start of a new era – until now, cars were isolated from their surroundings, but now the two will interact,” says Scheider. An entire metropolis, infrastructure included, could be networked to guarantee optimum mobility. Anyone wanting to travel from downtown to the outskirts could use a train in central districts and then switch to a car-sharing scheme later in the journey. Bosch platforms with service brokering allow public transportation companies, electric car hire companies, and e-bike rental companies to work together to offer an integrated mobility service.
Bosch software platforms already manage the infrastructure for major electromobility trials. One example is Hubject, the roaming system for charge spots, which allows customers to charge their electric car at charge spots belonging to various companies and pay conveniently via their normal electricity bill. But Bosch is also active beyond electromobility. Truck Secure Parking, for instance, is an online booking service for truck parking spaces along freeways. All the spaces feature video surveillance and are networked with a Bosch call center, which guarantees safety for drivers and freight.
Bosch is even working on how to put a whole city onto the internet of things. Bosch digital networking technology has been in operation in Monaco since mid-November 2013. This was the first step in putting into action a cooperation agreement signed by the Principality of Monaco and Bosch in July 2012. The project offers a glimpse of a future in which mobility is the primary focus of the connected city. There is no shortage of suitable applications – directing drivers to the nearest charge spot, booking and paying for parking spaces, switching to e-bikes as traffic dictates – and these developments can been found in all the world's megacities.
This is why Bosch considers automotive connectivity to be a global market. Customers and car companies around the world are getting to grips with how to network the car. Automated, connected vehicles can for instance improve traffic flow by 80 percent, or guarantee safe, comfortable mobility for older people. What's more, studies suggest that the number of road traffic fatalities could be reduced by up to 90 percent as vehicles become progressively more automated. In its efforts to connect cars to the internet, Bosch is in close dialogue not just with global automakers but also with innovative companies in other sectors – in Europe, North America, and Asia.
Broad range of applications - from ESP® to rollover detection
Can be used in applications up to ASIL D in accordance with ISO 26262
Optimized for robust operation and extremely space-saving
Bosch has launched a new generation of inertial sensors. The SMI7xy sensor platform is designed specifically for use in active and passive safety systems and in driver assistance systems. These new sensors are very robust and take up very little room, as they are supplied in a compact BGA housing that measures just 7x7x1.5 mm3.
The SMI7xy platform comprises four types of sensors in two categories: type SMI720 and type SMI740 sensors for basic applications, and type SMI700 and type SMI710 sensors for more demanding applications. Depending on their final application, the sensors can be used up to ASIL D (SMI720 up to ASIL C) in accordance with the ISO 26262 safety standard. All models feature an integrated safety controller; the SMI700 and SMI710 also offer a robust offset stability. When outputting data via their serial peripheral interface (SPI), the sensors use the two most widespread versions of SPI protocol.
Particularly suited to demanding vehicle dynamics applications The SMI700's housing contains a yaw-rate sensor (z axis) and a 2-axis acceleration sensor (x and y axis). This sensor can optionally register high accelerations of up to 35 g. In addition to its SPI, the SMI700 comes with a PSI5 interface and a CAN interface – two standard data output interfaces in automotive electronics. These characteristics make the SMI700 the ideal sensor for use in ESP® systems and in demanding vehicle dynamics applications such as hill hold control, adaptive cruise control, and active front steering.
The SMI710 also combines a yaw-rate sensor (x axis) with a 2-axis acceleration sensor (this time y and z axis). It features a PSI5 interface and a CAN interface. This means it is capable of detecting a rollover and meets the requirements for use in demanding driver assistance functions such as roll and pitch stability programs.
Rollover detection and ESP® The SMI720 sensor is designed specifically for rollover detection. Its housing contains a yaw-rate sensor (x axis) and a 1-axis acceleration sensor (z axis). Meanwhile the SMI740 has a yaw-rate sensor (z axis) and a 2-axis acceleration sensor (x and y axis). Since the SMI740 is designed according to standard ESP® specifications, it is tailored to basic vehicle dynamics control.
Samples of the SMI7xy are already available.
Background to MEMS technology Bosch has been at the forefront of MEMS (microelectromechanical systems) technology since the very beginning. Since the start of production in 1995, the company has manufactured well in excess of three billion MEMS sensors, with production volumes hitting new highs year after year. In 2013, more than a billion sensors rolled off the production lines at the company's Reutlingen plant. The range includes sensors for measuring pressure, acceleration, humidity, temperature, yaw rate, inertial, and geomagnetic field, as well as MEMS microphones for a wide range of applications in the consumer electronics and automotive industries.

Increased design freedom thanks to flexible orientation
For use in ASIL D airbag systems in accordance with ISO 26262
Bosch's latest generation of acceleration sensors makes developing airbag systems easier. With versions for use in the airbag control unit and versions for peripheral use in the vehicle's front, sides, and rear, the SMA6xy sensor platform simplifies the release approval process by giving sensors a common housing design whatever the application. All the sensors in the new SMA6xy product family are ideally suited to Bosch ASICs for airbag systems.
Better protection against microcuts The PSI5 sensor for peripheral use comes in versions offering measurement ranges of 120, 240, or 480 g (type SMA68x and SMA69x). In addition to the normal x and y channels, these sensors are now also available with a z channel for measuring acceleration in the vertical axis. So whatever the desired orientation of the sensor's installation, there is a version to match. This gives airbag system developers greater design freedom. Compared to previous versions, the new sensors are much better protected against microcuts – extremely brief interruptions in power supply to the sensor following an impact – and can now tolerate interruptions of up to 10 microseconds.
Designed to be installed in the airbag control unit, the SPI sensors can measure accelerations of up to 120 g (type SMA66x) and their readings have 12-bit resolution. An arming pin helps developers to initiate the airbag algorithm by showing when readings exceed a defined threshold value.
All sensors in the SMA6xy product family have a compact SOIC8n housing and are available in 1-channel (x, y or z axis) or 2-channel (x-y or y-z axes) versions. Since they are designed for use in safety-critical airbag systems, the sensors meet the criteria stipulated for the ASIL D safety level in accordance with ISO 26262.
Samples of the SMA6xy are already available.

Growing demand for locally produced automotive technology
Stuttgart/Samara – The Bosch Group has laid the foundation stone for its new plant in Russia: from 2015, Bosch automotive technology will also be rolling off the assembly line in Samara. The site itself covers a total surface area of some 200,000 square meters, the equivalent of about 29 soccer fields. The buildings will offer some 22,000 square meters of floor space and will be used for manufacturing, administration, and logistics. They will also house the site's power and media supply as well as a cafeteria. By the end of 2016, the global supplier of technology and services will have invested some 50 million euros in Samara. When work is completed, some 500 associates will be working there.
As a result of low vehicle density and vehicle age – almost every second car in Russia is older than ten years – Bosch expects the country's annual vehicle production to grow continuously, from almost two million today to some three million in 2020. "The new manufacturing site in Samara is the next step in our long-term strategy. We aim to expand our presence in this region and seize the opportunities that the market offers," says Gerhard Pfeifer, president of the Bosch Group in Russia and CIS, at the official laying of the foundation stone. "This investment reflects our positive expectations of the Russian market."
Nikolai Merkushkin, the governor of the Samara region, is also pleased about the Bosch Group's investment. "The commitment of a major global player like Bosch is significant for the Samara region's economic and social development. The location is becoming more attractive for investors and local specialists alike," Merkushkin said.
Production for local customers Until now, the Chassis Systems Control, Starter Motors and Generators, and Diesel Systems divisions have been present in Samara. In the future, the Electric Drives division will also have a home here. With the new plant, Bosch aims to manufacture automotive technologies primarily for local customers. These will include, for instance, anti-lock braking systems, starters and generators, common rail injectors for commercial vehicles, and windshield wiper systems. "By adding another local production site, we will be closer to our customers and will thus be better able to respond to their needs," said the Bosch representative Gerhard Pfeifer. "The location in the European part of Russia is perfectly suited to this aim, not least because of the region's highly-qualified specialist workforce and excellent infrastructure."
Presence in Russia The Bosch Thermotechnology division is currently building a new manufacturing site at its Engels location. From the summer of 2014, Bosch and Buderus wall-hung boilers and industrial-scale boilers will be produced there. Bosch's Automotive Aftermarket, Gasoline Systems, Diesel Systems, and Power Tools divisions already have a presence in Engels. After Engels, Samara will be the second Bosch plant to manufacture automotive technology in Russia. In addition to this, Bosch is investing more than 100 million euros in its new Russian headquarters in Moscow, which will have a total floor space of 57,000 square meters. The official opening of the new headquarters is scheduled for the second half of 2014.
Bosch has been present in Russia since 1904. The country was one of the first outside Germany in which a sales organization was established. The Bosch Group locations in Engels, Togliatti, and St. Petersburg manufacture automotive equipment, power tools, packaging technology, and household appliances. Once thermotechnology production begins, all four Bosch business sectors – Automotive Technology, Industrial Technology, Consumer Goods, and Energy and Building Technology – will have a presence in Russia. With its more than 3,000 local associates, the company generated sales of about one billion euros in Russia in 2012.
