Pedestrian Test Protocol - Euro NCAP

selected Bonnet Leading Edge impact points, which will be chosen in Section 6.
11.4.1 Position a horizontal straight edge with one end in contact with the impact point on the
Bonnet Leading Edge Reference Line and measure the vertical distance to the ground.
Alternatively use a 3D measuring arm to measure and record the Bonnet Leading Edge
height for each impact point.
11.5 Determination of Impact Velocity, Impact Angle and Impact Energy
11.5.1 The shape of the front of the car determines the velocity, angle of incidence and
kinetic energy of the impactor. Full details are given in EEVC WG17 Report,
‘Improved Test Methods to Evaluate Pedestrian Protection Afforded by Passenger
Cars’, December 1998. The velocity, angle of impact and total kinetic energy of the
impactor will be calculated from the bonnet leading edge height and bumper lead.
11.5.2 Determine the Bonnet Leading Edge Height and the Bumper Lead at each impact
point. These can be simply calculated using the previously digitised co-ordinates of
the bonnet leading edge location and its ‘equivalent’ point on the Upper Bumper
Reference line.
11.5.3 Determine the required impact velocity, angle and the kinetic energy for the value of
Bonnet Leading Edge height and Bumper Lead found in 11.5.1 using Figure 26,
Figure 27 and Figure 28.
