PReVENT links to passive safety community


In September PReVENT participated in the 5th Annual meeting of the MADYMO user community. This event is an annual event gathering a large community of experts on passive safety. PReVENT was invited to give a keynote presentation on the integration of passive and active safety. The speech presented by the active safety community attracted a great deal of attention since this field is seen as the next step up in improving passive safety components.


Besides an overall introduction to the European Commision DG INFSO and DG TREN and their activities within the EUCAR integrated safety programme, the presentation included detailed information on the requirements of the COMPOSE and APALACI subprojects and their links to the APROSYS integrated project. APROSYS SP6 is investigating side impacts and the effect of pre-crash systems triggering structural actuators. The sensor systems of APROSYS SP6 and COMPOSE will be integrated into a common demonstration vehicle.

 

The main goal of the passive safety community is to find other possible passive safety features for impacts in around 200 - 20ms. IP APROSYS for example,  has investigated systems that tilt the seat in order to push the passenger away from the door when a side impact is imminent. Other techniques are locking devices that fix the door to the car frame.

 

APALACI and APROSYS are looking together at the potential of applications such as pre-crash and pre-fire features. These features are very important since they could change the "fundamental rules" of crash detection. To date, most of the simulations for crash impacts within the passive safety community start at time zero, i.e. the time at which the impact occurs. However, it is clear that as the active safety pre-crash and pre-fire features are being developed, we are shifting away from this way of measuring and need to consider intervention of passive safety systems before the impact even occurs. APALACI is considering small sets of parameters that can be sent to the relevant passive safety systems exactly the same way as it is done from the body sensors but 200-20 ms in advance.

 

In conclusion, the future of passive and active safety will definitely need to adapt in order to protect the passengers. Some people claim that the basis of passive safety science will have to be changed when introduce in these new systems to the market. Airbag systems for example, will have to be retuned because the driver is pulled back by the belt earlier. The integrated projects PReVENT and APROSYS are working on this issue together.
