Division 3.1 Calculation of required powerF1

For each second j of the cycle trace, the power required to overcome driving resistance and to accelerate shall be calculated using the following equation:

$P_{required,j} = (\frac{f_{0} \times v_{j} + f_{1} \times v_{2}^{j} + f_{2} \times v_{3}^{j}}{3600}) + \frac{kr \times a_{j} \times v_{j} \times TM}{3600}$

where:

P_required,j

is the required power at second j, kW;

a_j

is the vehicle acceleration at second j, m/s², and is calculated as follows:

$a_{j} = \frac{(v_{j + 1} - v_{j})}{3,6 \times (t_{j + 1} - t_{j})}$ ;

is a factor taking the inertial resistances of the drivetrain during acceleration into account and is set to 1,03.
