Eco.Logic motion for economic driving

Lower fuel consumption and emissions

  • Profiles of the route ahead are integrated into the driving strategy
  • Unnecessary gear changes are avoided
  • Cash benefits for vehicle fleets
  • Bosch and Mercedes-Benz joint project development
  • Introduction to series production in late summer 2012

The search is on in the world of commercial vehicles for new ways not only to reduce the strain on the environment but also to lower costs in operating budgets. Fuel optimization for commercial vehicles is the goal of a new type of assistance system made by Bosch: Eco.Logic motion. Its focus is to use extended navigation data, such as information about gradients and bend curvatures, to optimize the engine and transmission control systems. Sophisticated algorithms ensure a reduction in both fuel consumption and CO₂ emissions.

Predictive sensor for more economic driving
Development engineers at Bosch's Car Multimedia division have devised special hardware that - through strict separation of the operating software and application software — is capable of also taking into account manufacturer-specific algorithms for cutting fuel consumption and emissions. Eco.Logic motion thus acts as a predictive sensor for optimizing the driving strategy.

Bosch has been able to accomplish the first series production project with this new system together with Mercedes-Benz Trucks. The jointly developed “Predictive Powertrain Control” system is being introduced to the new Actros in the late summer of 2012. Bosch is supplying the hardware, software platform and electronic horizon for this, and Mercedes-Benz has developed the corresponding application software.

Creating the dynamic electronic horizon
The system creates a three-dimensional image of the surroundings based on a digital map that also includes information on gradients and bends. 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” - that goes far beyond such near-field sensor technology as radar or video sensors.

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 ahead. 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.

Average fuel savings of three percent
Extensive studies carried out by Bosch involving realistic routes have re-vealed amazing potential. According to the findings, utilizing Eco.Logic mo-tion enables an average fuel saving of three percent to be achieved on German autobahns and highways, depending on the topography of the routes traveled. Accordingly, CO₂ emissions can also be reduced signifi-cantly. In the case of a 40 t truck with a high annual mileage, this means that at today's fuel prices even a reduction in fuel consumption of only one percent translates into a decrease in the overall operating costs of around EUR 650 per year.

This Bosch development therefore offers fundamental benefits through lower fuel costs and reduced pollutant emissions. It quickly pays for itself both in individual vehicles and in entire vehicle fleets and contributes to resource conservation. Furthermore, the hardware platform and system software provide Bosch engineers with other areas of application, such as in the field of hybrid, battery and thermal management. With such intelli-gent systems designed to meet specific needs, commercial vehicles will in future become even cleaner and more economical.
