Eco.Logic Motion developed by Bosch now also provides Daimler's Setra TopClass 500 coach with fundamental benefits through lower fuel costs and reduced pollutant emissions. "The focus is on optimized engine and transmission control through the use of extended navigation data, such as information about road gradients," explains Manfred Baden, President of the Car Multimedia division at Bosch. 


Bosch's Car Multimedia division and Mercedes-Benz Trucks jointly realized the first series production project incorporating Eco.Logic Motion. The system in the Actros that Daimler refers to as "Predictive Powertrain Control" was already introduced in the late summer of 2012. Bosch supplies the hardware, software platform and electronic horizon for this, and Daimler developed the sophisticated algorithms. This cutting-edge technology is now also optionally available in the Setra TopClass 500 coach. It will soon also be making an efficient contribution to resource conservation in further Setra coaches and in the Mercedes Travego, thus quickly paying for itself.


Predictive sensor for more economic driving 

Eco.Logic Motion acts, so to speak, as a predictive sensor for improving the driving strategy. Through strict separation of the operating software and application software, the hardware developed by Bosch is capable of also taking into account vehicle-specific algorithms and improving the energy efficiency. 


Creating the dynamic electronic horizon

The system creates a three-dimensional image of the surroundings based on a digital map that also includes information about the slope of the road. This image combined with precise data about the vehicle's location obtained via GPS (Global Positioning System) is used to calculate a preview of the vehicle's surroundings – referred to as the "electronic horizon".


Calculating a strategy for environmentally friendly driving

Based on the information gleaned from the dynamic electronic horizon and from the comparison with current vehicle parameters, the application software simulates an environmentally friendly driving strategy. For this purpose, it calculates a suitable speed and an appropriate gear selection for the route section that lies ahead of the coach. This information is then compared with current parameters and is transmitted to the vehicle's powertrain as instructions that are followed by the engine and transmission control units, thus enabling the vehicle, for instance, to accelerate when most appropriate or avoid unnecessary gear changes shortly before the crest of a hill.


Fundamental benefits through significant fuel savings

New test drives performed by Daimler on the topographically demanding A6 autobahn have now revealed amazing potential. According to the findings, utilizing Eco.Logic Motion enables an average fuel saving of more than nine percent to be achieved. Accordingly, CO2 emissions can also be reduced significantly. According to calculations by Bosch, for a coach with a high annual mileage and at today's fuel prices, even a reduction in fuel consumption of only one percentage point translates into a decrease in the overall operating costs of around 400 euros per year.

Automotive Technology is the largest Bosch Group business sector. In 2013, its sales came to 30.6 billion euros, or 66 percent of total group sales. This makes the Bosch Group one of the leading automotive suppliers (NB: Due to a change in accounting policies, the 2013 figures can only be compared to a limited extent with the 2012 figures). Automotive Technology largely operates in the following areas: injection technology for internal-combustion engines, alternative powertrain concepts, efficient and networked powertrain peripherals, systems for active and passive driving safety, assistance and comfort functions, technology for user-friendly infotainment as well as car-to-car and Car2X communication, and concepts, technology, and service for the automotive aftermarket. Bosch has been responsible for important automotive innovations, such as electronic engine management, the ESP anti-skid system, and common-rail diesel technology. 


The Bosch Group is a leading global supplier of technology and services. In 2013, its roughly 281,000 associates generated sales of 46.1 billion euros. (NB: Due to a change in accounting policies, the 2013 figures can only be compared to a limited extent with the 2012 figures). Its operations are divided into four business sectors: Automotive Technology, Industrial Technology, Consumer Goods, and Energy and Building Technology. The Bosch Group comprises Robert Bosch GmbH and its roughly 360 subsidiaries and regional companies in some 50 countries. If its sales and service partners are included, then Bosch is represented in roughly 150 countries. This worldwide development, manufacturing, and sales network is the foundation for further growth. In 2013, the Bosch Group invested some 4.5 billion euros in research and development and applied for some 5,000 patents. This is an average of 20 patents per day. The Bosch Group’s products and services are designed to fascinate, and to improve the quality of life by providing solutions which are both innovative and beneficial. In this way, the company offers technology worldwide that is “Invented for life.”
