Project goal

Predictive power management based on environment sensor technology

  • Determination of the currently required power
  • Prediction of actuator use and power based on environment sensor technology
  • Prediction of additional required power
  • Prediction of the available power reserve
  • Increase of power reserve by early disconnection of loads and/or increase of generator power


  • The aim of the joint project is to design and demonstrate new wiring system concepts for future automated vehicles that ensure the reliability of power and signal distribution.
  • For safe power supply, the concept provides for predictive power management, which uses the new autonomous driving functions to predict the expected power requirements. In this way, safety-critical states are anticipated and compensated for via measures initiated ahead of time. The efficiency of this method is optimized via an on-board network topology to be defined in the project and a  potential control using power semiconductors.
  • Heterogeneous redundancy via a powerline-based bus system is planned for secure communication. To reduce costs, this system will be specifically designed only to maintain safety-critical functions.

Pillars of the project

To achieve the overall goal of a stable and expandable vehicle electrical system for future vehicle applications, the ToSKa funding project is based on three pillars:

  • Power and Energy
  • Communication
  • Topology
