Hybrid Accelerator mapping - EXPERIMENTAL

warning

EXPERIMENTAL FEATURE - Use with caution. Functionality may be unstable.

Disambiguation

The term 'throttle' originates from gas/combustion engines, where it refers to a control element for acceleration. As we transition to electric vehicles, we prefer the term 'accelerator'. Both terms can be used interchangeably as synonyms.

Operating Principle

Dynamic accelerator control method:

• Low speed: Voltage (speed) control
• High speed: Current (torque) control

Activation

1. Set /acc/drvmode to 40
2. Adjust parameters for optimal accelerator response

Configuration Parameters

info

Parameters located in /acc/acc_opts folder

Parameter	Description
thr_curr_offset	Voltage mode current scaling: 0: Current scales with voltage 1: Current remains at 100%, voltage scales with accelerator
CUR_enter_margin	Current mode activation threshold (when drv_rel_voltage exceeds this value)
VLT_enter_margin	Voltage mode activation threshold (when drv_rel_voltage falls below this value)

Status Indicators

Variable	Description
drv_rel_voltage	Normalized motor speed (0-1)
drv_rel_current	Normalized motor current (0-1) 1 = phase current equals iref
