Accelerator System

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.

tip

Review these concepts first:

warning

Disable motor power before accelerator configuration to prevent unexpected motor activation.

Use stop command to disable motor until the run command (Release) or the next power cycle.

Acceleration Control​

Signal flow:

  1. Accelerator input passes through safety block (device arming control)
  2. Signal multiplied by acclvl parameter (maximum acceleration limit)
  3. Resulting signal (sig_acc) feeds into state machine
  4. Driver receives sig_acc as command
  5. drvmode parameter determines motor control method

Advanced features available:

  • Accelerator/brake fusion
  • Electronic clutch
  • Selectable motor modes

tip

Start with Basic accelerator configuration using a single accelerator input before implementing advanced features.

System States​

sig_acc [-1 to 1]​

Normalized acceleration command signal used by driver.

Configuration Parameters​

acclvl [0 to 1]​

Map-specific accelerator scaling parameter. User map details.
