Resumen:
Una universidad alemana ha desarrollado un sistema de monitorización y suministro eléctrico de a bordo que procesa los datos medidos dentro de un vehículo en una unidad de monitorización central y calcula el estado integral de la red de a bordo. Este sistema también permite identificar averías mediante la modelización de la red eléctrica y hacer hipótesis razonables de posibles errores y fuentes de error. La universidad busca compañías e institutos en los sectores de automoción, suministro eléctrico o redes de a bordo con el fin de mejorar y adaptar la tecnología a necesidades específicas y establecer acuerdos de licencia y cooperación en materia de investigación.

Tittle:
On-board power supply system-monitoring in vehicles
Summary:
A German university developed an on-board power supply system-monitoring that processes the measured data within vehicles in a central monitoring unit and calculates the overall state of the on-board network. It can also identify faults by modeling the power network and making reasonable assumptions about possible errors and sources of errors. The university is offering a license agreement and a research cooperation agreement.
Description:
The vehicle electrical system has become more and more complex over the years. Thus the error probability increases, but an accurate fault identification and isolation becomes more and more difficult. In today´s systems, there are already several sensors that measure current or voltage at specific points, but they are mainly for a self-diagnosis purpose of individual control units. The number of sensors would have to be significantly increased for enabling previously used methods to monitor the entire wiring system.

A German university developed an on-board power supply system (pps)-monitoring that processes the measured data of the existing sensors in a central monitoring unit and calculates the overall state of the on-board network with a high accuracy. The system can identify faults by modeling the power network and making reasonable assumptions about possible errors and sources of errors. Faults in electrical branches, which are not directly accessible by sensors, can also be detected with the on-board pps-monitoring.
With this system all relevant faults can be modeled, detected and isolated. In addition to classic fault models, e.g. (creeping) short circuits, line breakages, contact loss, aging / corrosion / contact deterioration or loose contacts, also complex fault events, e.g. arcs in 48 V vehicle networks, can be detected. It can be used in the planning process of a power network. By optimizing the distribution of measuring points, a complete monitoring of the on-board network can be achieved with a minimum number of sensors.

The university is offering a license agreement and a research cooperation agreement in order to enhance this technology and adapt it to the needs of the partner organisations or their customers. This profile addresses companies and institutes dealing with automotive and electric power supply or on-board grid.
Advantages and Innovations:
Current technologies examine the onboard electronic locally, directly at the sensor. The technical innovation of the presented technology enables the measurement of the total physical state of a vehicle and provides a model of the total onboard electronic.

Other advantages are:
- Continuous simulation and control of the power supply system state
- Detection of faults
- Control of network branches without sensors also possible
- Also applicable to hybrid power supplies
- Useful aid for on-board power supply design
Stage of Development:
Field tested/evaluated
IPs:
Patent(s) applied for but not yet granted
CommeR Statunts Regarding IPR Status:
A German patent application was filed, international applications are still possible.

Partner sought

Type and Role of Partner Sought:
