ECE-R 13

<< Zu den ECE-Regelungen
Vorschriften zur Bremsanlage und zu Messungen an der Bremsanlage.
Agreement concerning the adoption of uniform technical prescriptions for wheeled vehicles, equipment and parts which can be fitted and/or be used on wheeled vehicles and the conditions for reciprocal recognition of approvals granted on the basis of these prescriptions.

Es wird u.a. die mittlere Vollbremsverzögerung (MFDD - mean fully developed deceleration) definiert, also die mittlere Vollverzögerung bezogen auf den Weg im Bereich (0,8 ... 0,1) ⋅ v₀. Für v in km/h berechnet sich mit MFDD in m/s² wie folgt:
[math]\displaystyle{ MFDD \equiv \frac {v_{b}^2 - v_{e}^2}{25,92 \cdot (s_e - s_b)} }[/math]
mit:
v₀ = initial vehicle speed in km/h,
v_b = vehicle speed at 0,8 v₀ in km/h,
v_e = vehicle speed at 0,1 v₀ in km/h,
s_b = distance travelled between v₀ and v_b in metres,
s_e = distance travelled between v₀ and v_e in metres.
