Intelligent Control of Components and energy flows in electrical vehicles
A German university developed a new decentralized control system for electrically operated vehicles. The electrical consumers (components) are equipped with microprocessor-based controller units that regulate, control and read vehicle data independently. The university offers a license agreement as well as a technical cooperation agreement.
Partner expertise sought
A German university offers a decentralized control system for electrically operated vehicles. This system manages various, similar control units of the electrical consumers in the vehicle. Thus it is able to optimise the energy flow of all electrical consumers operating. The electrical consumers (components) of this system are equipped with microprocessor-based controller units (multi-agents), which are able to regulate, control and read vehicle data independently. In addition, these controllers are connected to one another via a bus or a radio system in order to achieve an optimum interplay of the individual components by means of data exchange. The control system evaluates data of the route, weather and traffic, in order to ensure optimal energy and performance management for the vehicle. Thus any journey can be intelligently and continuously optimized in accordance with the wishes of the driver (range, speed, comfort, etc.), depending on the remaining driving distance, the external circumstances and the level of the batteries, without the driver having to intervene actively in the process. The invention is also able to compensate for the failure of one or more controller units by the other units, so that the operation can be continued even with minor defects. This is fully automatic due to the uniform structure of all controllers, their intelligence and the communication system used. If a controller fails during operation, it is restarted by the other controllers. If the restart fails, its functions are immediately taken over by other controllers. The control system can be used as a vehicle control system in all electric vehicles and also in conventional vehicles. The flexibility - plug-and-play of controllers at any time - and the redundancy offered by the multi-agent concept ensures a very high reliability. The continuous assessment of all internal and external parameters for the vehicle's control makes it possible to improve driving comfort and / or range. Experiments have shown an increase in the range of up to 45% compared to previous energy management concepts. The controllers are based on simple electronic components and are cost-effective. The university offers a license agreement as well as a technical cooperation agreement to companies that are interested in a further development of the methodology. A further technical development could for instance lead to additional functionalities, different electronic components or programming languages.
Advantages and innovations
In comparison to present proceedings the presented control system works decentralised. Various, similar control units manage the electrical consumers. It is – so to speak – a distributed control system. Other competitive advantages are: - Completely new concept - Increases the range of the car - Increases reliability of the car - Low cost - Identical controller hardware - Plug & Play

How it works
- Tell us about yourself
- We’ll discuss with you
- We put the right partners in touch
EEN help you find the right partner, rather than you going it alone.
Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.
These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.
Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
First we need to check you’re human.
