calculateEES – An Objective Estimation

The development of calculateEES was funded by ADAC.

The underlying EES models were developed with the support of the following project partners and institutions:

• Allgemeiner Deutscher Automobil-Club e.V. (ADAC)
• The European New Car Assessment Programme (Euro NCAP)
• Forschungsvereinigung Automobiltechnik (FAT) e.V.
• Dr. Ing. h.c. F Porsche AG
• VOLKSWAGEN AG

The Energy Equivalent Speed (EES), as an important parameter of traffic accident reconstruction and traffic accident research, is of great importance as an equivalent of plastic deformation energy. However, previous methods for EES estimation are often subject to a subjective influence. The platform developed by Fraunhofer IVI is to be applied equally in traffic accident reconstruction as well as in traffic accident research in order to obtain objective estimates for the EES value of a deformed passenger car. The estimates are based on so-called EES models, which have already been derived from real accident data (GIDAS, NASS CDS) and crash test data (Euro NCAP) in previous projects.

The calculateEES progam uses three-dimensional voxel models to visualize the deformations of a vehicle whose data you have entered. The models required for this are provided to you with the program download. You can choose between seven different model shapes (compact car, station wagon, SUV, ...). In addition to this, the impact direction also influences the estimated EES. For more information, please refer to the program. 

Since the actual estimation of the EES values is based on large amounts of data, the calculation takes place exclusively on a Fraunhofer server. Therefore, the calculateEES program requires an internet connection and access data (see registration) to objectively estimate an EES value.

What information do we need from you?

• Model shape and direction of impact in order to select the appropriate EES model
• Deformations given in centimeters
• (optional) your own professional estimate of the EES
• (optional) anonymized photos of the deformations in order to build up a comparison database

What do you get from us?

• an objective estimation of the EES based on the entered data
• (future/development: objective EES, photos and subjective EES estimates of other testers from comparable cases)

Please note: This is a research project. We would like to support you with our platform. A plausibility check of the results before further use is required in any case. The use is at your own risk.

calculateEES is funded as part of a research project. This means that both the download and the use of the program are free of charge during the project period until the end of 2021.

From 2022 on, the operating costs must be financed in a different way. In this context, Fraunhofer, as a non-profit organization, is not allowed to make a profit. If registered users agree, we will inform them about current developments in this regard.

Registration is required to download the program. After sending your data we will check your request and contact you if necessary. After you have read and countersigned the terms and conditions sent by us, we will send you a download link together with personalized access data for the program.
