| Summary | ACSF systems in use were brought to market based on exemption approvals in the EU. These systems show a good and safe performance. Approvals according to UN R79/03 would force modifications to currently used systems without any apparent safety benefit. The current formula for the calculation of scritical does not take the dynamic behaviour of the vehicles into account, therefore requires gaps that under some traffic conditions don’t usually occur. Since there are different ways of addressing the dynamic behaviour of the vehicles with regard to the original formula, this proposal would allow the manufacturer to specify its own formula provided the safety principle is maintained. | ||||||||
