Electric vehicle
EV_REGENERATIVE_BRAKING_STATE
What it is
Regenerative braking or one-pedal drive setting of the car
Returns the current setting associated with the regenerative braking setting in the car
If the OEM requires more setting than those provided in EvRegenerativeBrakingState, the EV_BRAKE_REGENERATION_LEVEL property can be used instead, which provides a more granular way of providing the same information.
