ParameterDescriptionDimension
1. Flow sub-tabUse to set the power flow line. If there are multiple power flow lines (Parallel HEVE), you should set up additional flows.N/A
2. Flow NameUse to set the flow name.N/A
3. Use power split moduleUse to select a power split model in a selected flow. To use the power split, the number of power sources in the flow must be one.N/A
4. Power sub-tabUse to set power properties. For a series HEV model, you should set additional power profiles.N/A
5. NameUse to set the power profile name.N/A
6. RoleSet the power role. General is used when you are only considering an output source (such as an engine), Regenerative Brake represents a regenerative power source (such as an electric motor).N/A
7. 3D chartShow the 3D chart of the torque map.N/A
8. Open File (torque map)

Use to set the torque map. There are two methods for this.

The first method is to use a configuration file (*.config). You should create an APS-Torque profile for each RPM and enter its file name and RPM in the configuration file as shown below. The configuration file and APS-Torque file must be located same folder.

Power tab parameters

The second method is using a torque map file. The format for this is shown below.

N/A
9. Regenerative brake ratioUse to set the regenerative brake ratio. This value is set to distribute wheel braking torque and regenerative torque for the maximum braking torque required. This ratio should be set by a profile in the time domain. The value of Y defines the regenerative braking torque and (1-Y) the wheel braking torque.N/A
10. Open fileUse to set the regenerative brake ratio by a file. The file format is as below.N/A
11. 2D chartRegenerative brake ratio is shown in 2D chart.N/A
12. Enable ClutchUse to select the clutch model. If there is no clutch for power, engine torque is assumed as a clutch torque.N/A
13. Clutch stiffnessUse to set the clutch stiffness.Torque/rad
14. Damping coefficientUse to set the clutch damping coefficientN/A
15. Engage durationUse to set the engage duration time of the clutch.Time
16. Disengage durationUse to set the disengage duration time of the clutch.Time
17. Shift durationUse to set the shift duration time of the clutch.Time
18. Moment of InertiaUse to set the moment of inertia. You should input the equivalent moment of inertia to represent the clutch and engine.Mass/Length^2
19. EngageUse to set up the engage profile. The X axis value profile should be 0~1(normalization). This profile is used by multiplying by the engage duration.N/A
20. DisengageUse to set up the disengage profile. The X axis values should be 0~1(normalization). This profile is used by multiplying by the disengage duration.N/A
21. Open fileUse to set the engage and disengage profiles. The file format is csv.N/A
22. 2D chartEngage and disengage profiles are shown in a 2D chart.N/A
23. 3D Chart

Show the 3D chart of power split map

(23~31 are visible only when the power split is active)

N/A
24. Open file

Use to set the power split map. This power split map uses a *.mcm file. You should create a Vehicle Speed (km/h) to RPM profile for each APS.
