4.24.1. Overview

The User Select Drive Mode component allows the driver to select different drive modes and regen modes. It processes the driver requests and saved modes to determine the selected drive mode, regen mode and pedal map. It also allows overriding the modes and pedal map via calibration parameters.

4.24.2. Functions

	Title	Description
1	Drive Mode Selection	Determines the selected drive mode based on driver request and saved mode. Allows overriding the drive mode via calibration parameter.
2	Regen Mode Selection	Determines the selected regen mode based on driver request and saved mode. Allows overriding the regen mode via calibration parameter.
3	Pedal Map Selection	Determines the pedal map based on the selected drive mode and regen mode. Allows overriding the pedal map via calibration parameter.

4.24.5. Calibration

UsrSelDrvMod allows tuning and customisation of the pedal response for different drive and regen modes.

4.24.5.1. Step 1 - Select override condition for driver request

Set UsrseldrvModDrvrModOvrd to true to override the driver’s requested mode with the value set by UsrseldrvModManDrvMod for drive mode, and UsrseldrvModManRgnMod for regen mode. If set to false (default) the drive and regen modes are taken from Inport #5: DrvrDrvModReq and Inport #6: DrvrRgnModReq respectively.

4.24.5.2. Step 2 - Select drive mode and corresponding pedal map

If UsrseldrvModDrvrModOvrd is set to true, use UsrseldrvModManDrvMod to select the desired drive mode:

• 1 to select Na mode

• 2 to select Gt mode

• 3 to select Sport mode

4.24.5.3. Step 3 - Select regen mode and corresponding pedal map

If UsrseldrvModDrvrModOvrd is set to true, use UsrseldrvModManRgnMod to select the desired regen mode:

• 1 to select Na

• 2 to select High

• 3 to select Low

4.24.5.4. Step 4 - Configure pedal maps

The combination of drive and regen modes result in various predefined pedal maps. These maps can be tuned with UsrseldrvModPedlMap and are active as follows:

• Map 1: Active when drive mode is 2 (Gt) and regen mode is 2 (High)

• Map 2: Active when drive mode is 2 (Gt) and regen mode is 3 (Low)

• Map 3: Active when drive mode is 3 (Sport) and regen mode is 2 (High)

• Map 4: Active when drive mode is 3 (Sport) and regen mode is 3 (Low)

4.24.5.5. Notes

UsrseldrvModMemOkOvrd can be used if saved modes need override.
