Proposal to address new active suspension technologies that can raise the height of the vehicle in motion up to a defined speed. Since the vehicle height has an influence on the headform test area (WAD) and on the test results for legform tests, all possible vehicle heights up to a driving speed of 11.1 m/s (40 km/h) should be considered to be relevant for the impact with a pedestrian. The proposal is a clarification on this issue.To ensure that such an active suspension system is considered for type approval, there should be a detailed description in the information document. Due to the fact that extensions for an existing vehicle type concerning UN Regulation No. 127 are still possible according to 00 and 01 series of amendments, the proposal is relevant for all series of amendments of the UN R127.
