Efficient Hybrid Propulsion using Vehicular Communication

The objective of the Hy-Nets project is to develop a novel approach for improving the resource and energy efficiency of connected hybrid vehicles. Hybrid propulsion systems on a test bench are connected to a simulation of the vehicle environment and of the communication between the connected vehicles. This way, new insights can be derived from the influence of realistic traffic environments. 

Hy-Nets aims at bundling several topics of vehicle technology that have only been observed separately so far. By doing so, the project partners want to open up entirely new efficiency potentials for the hybrid vehicles of tomorrow. In contrast to existing controls of hybrid drives, which are primarily based on vehicle-internal information, Hy-Nets for the first time also considers Car2x communication, i.e., the communication between vehicles and/or between vehicles and the infrastructure.

It is this holistic approach that brings entirely new efficiency maximization methods into researchers’ focus. These methods include predictive energy management, new autonomous driving functions and, especially, the cooperation of communicating vehicles in cooperative traffic scenarios.

To accurately analyze the interaction of the real hardware and software of a hybrid drivetrain in complex traffic scenarios, Hy-Nets is building a prototype of a state-of-the-art hybrid drive. On a test bench, the prototype is connected to a powerful hardware-in-the-loop (HIL) simulator that simulates the traffic environment of the hybrid vehicle, the general traffic flow, and the entire vehicle and infrastructure communication with utmost precision. In this setup, the ASM tool suite is used to simulate certain electric components of the vehicle, the vehicle dynamics, and the traffic environment.

The project is conducted by the project partners dSPACE, DENSO, RWTH Aachen University and the Paderborn University. They are supported by the city of Paderborn and the engineering office Geiger & Hamburgier (IGH) as associated partners. Hy-Nets originated in a research project funded by the European Union and the German Federal State of North Rhine-Westphalia.
