Current strategies to minimize energy consumption are build on numerous parameters in the vehicle itself. To this end, the overall vehicle and its components are systematically further developed to ensure the greatest possible efficiency. Electrification in hybrid vehicles is one of these strategic steps. This makes driving strategies such as regenerative braking, coasting (decoupling and deactivating the internal combustion engine), eBoost (support from the electric motor for the internal combustion engine), load point shifting, and extended start/stop operation possible. For example, with a mild hybrid based on the 48 volt hybrid Eco Drive, savings of between 8% (cross-country driving only) and 21% (in urban traffic, [2] can be achieved, using an integration-friendly P0 architecture via integration at the engine belt. This high level of fuel saving is the main reason for the attractive cost-benefit ratio of the 48 volt system. By means of predictive driving strategies, transmitted information about the vehicle environment, and an online connection to a backend with dynamic information, it can be used even more efficiently and user friendly.

The presented such connected operating strategies for the powertrain uses data about the surrounding area to allow proactive action instead of a purely reactive control system. Using a 48 volt mild hybrid BSG demo vehicle as an example, Continental shows what saving effects are possible with Connected Energy Management (cEM) on a real route if sensed information about the surrounding area is kept constantly up to date by means of a backend connection.

Another focal point of the paper is the technical realization.

The architecture incl. the backend and data- landscape are shown in a product related shape.
