Development skills in passive vehicle safety
Developments in passive safety mean designing vehicles with a maximal reduction of accident consequences for passengers, involved parties and other road users. A high degree of passive safety is achieved through maximum absorption of energy in the chassis, coordinated restraint systems and appropriate design in the interior of the vehicle. In this way, passive safety is an overall function of a vehicle, which is to be achieved through optimal cooperation between all the components involved.
Our strengths
Functional development
This comprises the optimal adjustment of all components involved and the adaptation of the entire performance to achieve complete product properties. We support you in turning global product targets, such as, for example, a specific consumer protection agency on a specific market, into necessary constituent targets (passive safety).
When it comes to functional development in simulations and tests, we concentrate on the following:
- Total system simulations (all load conditions of passive safety)
- Crash analysis
- Battery casing
- Interior (cockpit, seats, door trim)
- Restraint systems
- Connection technology
Functional levels of passive safety in the development process
Overview functional levels:
1. Global Safety (Active & Passive)

Methods & Tools
Form-finding methods
Which is the ideal shape for a side airbag under the given weight constraints? With our automated form-finding methods, it’s possible to determine the ideal coverage area for an airbag using an automated CAE process.
Robustness
Methods of testing robustness become relevant in relatively narrow solution spaces. If systems are already designed close to the technical limits, natural variations in starting constraints may pose the risk of systemic failure. We establish the effects of the dummy sitting position on the robustness of the crash results.
Training concept for passive vehicle safety (CAE & testing)
We see a considerable distinction in our employees’ specialist development. We train our employees, in accordance with an established concept, in all design disciplines of passive safety, current standards and requirements, and in using crash-specific tools, such as CAE Solver.
We offer this training in German, English, Chinese and Japanese worldwide.
