Always technically challenging
Shaping the automotive future is our goal!
In our daily work we thrive for innovative solutions that help our mother companies to move forward. Here, we want to share some insights of the projects we did in the past. Of course, there is much more which we cannot publish yet, but some of our solutions might be working in your own car already.
The SeeRoad project, funded by the Federal Ministry of Economics and Energy (BMWi), is developing a system for condition monitoring of the roadway with the help of vehicles, where the realization of high automation is possible even in demanding driving situations. Intedis is in-charge of the implementation of the central data fusion. More information at www.seeroad.uni-bremen.de.
The project AutoKonf was founded by the Federal Ministry of Education and Research (BMBF). The consortium of this project has produced a video introduction with the core themes of the project. The primary focus here is to develop a solution for failure protection in terms of safety-critical driving functions, targeted for Level 4 automated driving. Further information can be found on the website www.autokonf.de.
The motivation for the iPDN (Intelligent Power Distribution Node) project originates from the introduction of fully autonomous driving. In addition to the sensors, the control units and the actuators, the power supply and communication must be designed to be fault tolerant. The result of the project is an on-board power network concept that effectively implements the fault tolerance requirements for realizing automated driving. The iPDN was realized as an intelligent power distributor, that can be used in different on-board systems for the various stages of automated driving. The operating capability has recently been proven via vehicle integration tests.
Energy storage system
Intedis is particularly interested in with the energy distribution and storage in vehicles. Here, we look at the entire spectrum from the classical 12 V to 3-voltage architectures found in state-of-the-art electric vehicles.
The focuses are not only on the storage of energy in lead or lithium-ion batteries, the power supply through the harness and the protection of the electrical components, but also on the performance profiles and energy-saving features such as recuperation or sailing. The goal here is to optimize the distribution and storage of electrical energy, as well as the operational safety of electrical components.
The project was implemented from 2010 to 2013 within the Seventh Framework Program of the European Union. The goal was to develop a next-generation electric vehicle with minimal energy consumption. The target vehicle was supposed to dynamically optimize its decisions between safety and energy efficiency.
The project “Harness Lightweight” was carried out together with a German car manufacturer. The aim was to reduce cable weight by optimizing the cross-section of the entire wiring harness (over 3000 cables) of a vehicle. Weight savings of 6 kg could be achieved by realizing a detailed analysis of all requirements, a finer adjustment of the line fuses and improvements in the development process.
This project was federally funded. Its aim was to develop an electronic solution for switching and protection of electrical loads and their supply lines. Different hardware solutions, as well as an innovative mechanical realization were tested for better cooling of the semiconductors. Besides that, a flexible software was developed for monitoring and control. At present, we still use the insights gained from the project for current topics such as autonomous driving.
