Output Files / Summary Results (.vsum)

The .vsum file includes total / average results for each calculation run in one execution (ie. click of START Button). The file is located in the directory of the fist run .vecto file.

Quantities:
Name Unit Description
Job [-] Job number. Format is "x-y" with x = file number and y = cycle number
Input File [-] Name of the input file
Cycle [-] Name of the cycle file
time [s] Total simulation time
Prated [kW] Rated engine speed. See Engine Editor
distance [km] Total travelled distance
speed [km/h] Average vehicle speed
road grad [%] Average road gradient (time-averaged)
n_norm [-] Average normalised* engine speed
Pe_norm [-] Average normalised* engine power
Ppos [-] Average normalised* positive engine power
Pneg [-] Average normalised* negative engine power
FC [g/km] Average fuel consumption
Pbrake [-] Average normalised* brake power (not including engine drag)
EposICE [kWh] Total positive engine work
EnegICE [kWh] Total negative engine work (engine brake)
Eair [kWh] Total work of air resistance
Eroll [kWh] Total work of rolling resistance
Egrad [kWh] Total work of gradient resistance
Eacc [kWh] Total work from accelerations (<0) / decelerations (>0) 
Eaux [kWh] Total energy demand of auxiliaries
Ebrake [kWh] Total work dissipated in mechanical braking (sum of service brakes, retader and additional engine exhaust brakes)
Etransm [kWh] Total work of transmission losses
Mass [kg] Vehicle mass (equals Curb Weight Vehicle plus Curb Weight Extra Trailer/Body, see Vehicle Editor)
Loading [kg] Vehicle loading (see Vehicle Editor)
a [m/s2] Average acceleration
a_pos [m/s2] Average acceleration in acceleration phases**
a_neg [m/s2] Average deceleration in deceleration phases**
Acc.Noise [m/s2] Acceleration noise
pAcc [%] Time share of acceleration phases**
pDec [%] Time share of deceleration phases**
pCruise [%] Time share of cruise phases**
pStop [%] Time share of stop phases**

*Normalisation
Normalised engine speed = (n - n_idle)/(n_rated - n_idle)
Normalised power = Pe / Pe_rated

**Driving conditions:
Acceleration: a3s > 0.125 [m/s2]
Deceleration: a3s < -0.125 [m/s2]
Cruise: -0.125 ≤ a3s ≤ 0.125 [m/s2]
Stop: v < 0.1 [m/s]
Note: a3s = 3 seconds-averaged acceleration 

Definition of work (E...):
sign > 0: positive work applied to the vehicle (e.g. from engine, from kinetic energy)
sign < 0: losses
Sum of: EposICE, EnegICE, Eair, Eroll, Egrad, Eacc, Eaux, Ebrake and Etransm is zero (besides small rounding error for long driving cycles)
