Max. acceleration and brake curves (.vacc Input File)
Limits vehicle acceleration and deceleration depending on vehicle speed. If Look-Ahead Coasting is enabled then the deceleration is applied in the brake phase.

Input File Format
(comma-separated, dot = decimal-mark):
c vehicle speed Max. acceleration Max. deceleration
c [km/h] [m/s2] [m/s2]
... ... ...
... ... ...
Note: text lines (header, comments, etc.) must start with "c "

Engine Start/Stop
If enabled the engine will be turned off if:
  • Power demand (without Aux) ≤ 0
  • Vehicle speed is below Max Speed [km/h]
  • Engine was running for at least Min ICE-On Time [s]
Note: Currently there is not method defined to compensate invalid auxiliary cycle work when Engine Start/Stop is enabled, i.e. if enabled the total auxiliary work is less than without Start/Stop



Overspeed / Eco-Roll


Overspeed
If Pwheel < 0: Coasting with brakes not applied for speed < target speed + allowed overspeed
Parameters:
  • Minimum Target Speed
  • Allowed Overspeed



Eco-Roll
If Pwheel < 0: Neutral gear, engine idling. Engine- and service- brake if target speed + allowed overspeed is reached. Normal driving if target speed + allowed underspeed is reached.
Parameters:





Look-Ahead Coasting
Enables coasting before each braking phase. Coasting will begin at T seconds before new lower target speed (see picture below). Braking deceleration is defined by the .vacc file.
Parameters:
  • Target Retardationalookahead
  • Minimum Target Speed
Note: If road gradient > 0 the coasting deceleration will not be affected, i.e. coasting deceleration is calculated for road gradient=0. This should prevent the vehicle from decelerating too fast. If road gradient < 0 and Pwheel < 0 coasting is disabled (else the vehicle would accelerate).
