One-Pedal Driving
One-pedal driving is a drive mode in which easing off the accelerator commands substantial deceleration, usually using regenerative braking and, when needed, blended friction braking.
How it behaves
Depending on the vehicle, lifting the accelerator may slow the car to a crawl, bring it to a complete stop, and hold it there. Other systems require the brake pedal for the final stop. Strength, low-speed behavior, and whether the setting is remembered can vary by mode and software.
One-pedal driving does not remove the brake pedal or guarantee that the requested deceleration is available. Regeneration can be limited by a full or cold battery, low traction, speed, motor limits, or system conditions; the vehicle may blend friction brakes or ask the driver to brake.
The feature changes pedal control, not the physics of energy recovery. Smooth anticipation can recover some kinetic energy, but coasting may be more efficient when slowing is unnecessary. See Regenerative Braking for regeneration limits, brake blending, and vehicle-specific behavior.
