Efficacy of System Warning, Brake Assist, Automatic Braking

7 Efficacy of System Warning, Brake Assist, Automatic Braking  

For system Warning, brake assist, automatic braking the TTC of the earliest warning was subject to variation, whereas the configuration of the brake assist and the automatic braking was not changed. Again, the fluctuations of the Monte-Carlo simulation with one million situations is visible, as discussed above.

Although the U-like shape of the warning NNTs aUow for an easy determination of the optimum range with respect to the parameter in variation (i.e., warning TTC in this example), the L-like shape of the intervention NNT requires a more subtle interpretation in order to find an optimum. The question is how both NNTs have to be interpreted in combination to find the optimal strategy and the operating point for the whole system. It is evident that a quantity including both of these characteristics is needed.
