Division 6.1.6 Data reportingF1

The data recorded during the verification testing procedure shall be reported to the approval authority that granted the licence to operate the simulation tool as follows:

1. (a)

   The data recorded shall be reported in a constant 2 Hz signals as set out in Table 1. The data recorded at higher frequencies than 2 Hz shall be converted into 2 Hz by averaging the time intervals around the 2 Hz nodes. In case of e.g. 10 Hz sampling, the first 2 Hz node is defined by the average from second 0,1 to 0,5, the second node is defined by the average from second 0,6 to 1,0. The time stamp for each node shall be the last time stamp per node, i.e. 0,5, 1,0, 1,5 etc.

2. (b)

   The wheel power shall be calculated from the measured wheel torque and rotational wheel speed. All values shall first be converted into 2 Hz signals in accordance with point (a). Then the wheel power for each driven wheel shall be calculated from the 2 Hz torque and speed signals as set out in the following equation:

   $P_{\mathrm{wheel-i}\left(t\right)}=\frac{2\times \pi \times n_{\mathrm{wheel-i}\left(t\right)}\times {\mathrm{Md}}_{\mathrm{wheel-i}\left(t\right)}}{60000}$

   where:

   i

3. Index standing for left and right wheel of the driven axle

P _{wheel-i (t)}

4. power at the left and right driven wheel time node (t) [kW]

n _{wheel-i (t)}

5. rotational speed of driven the left and right driven wheel at time node (t) [rpm]

Md _{wheel-i (t)}

6. measured torque at the left and right driven wheel at time node (t) [Nm]

The wheel power input data for the verification test simulation with the simulation tool shall be the sum of the power of all driven wheels of the vehicle as set out in the following equation:

$P_{\mathrm{wheel}\left(t\right)}=\sum _{i=1}^{\mathrm{wd}}{P}_{\mathrm{wheel-i}\left(t\right)}$

where:

P _wheel(t)

7. total power at a driven wheel at time node (t) [kW]

wd

8. number of driven wheels
