What Does One-Pedal Mode Mean?
4 Answers
One-pedal mode refers to a driving method where the driver can control both acceleration and deceleration of the vehicle using a single accelerator pedal. Pressing the pedal accelerates the vehicle, while lifting off the pedal applies braking, with the braking force increasing linearly as the pedal is released. Below is a detailed explanation: Functions of one-pedal mode: When the throttle is released, it allows the wheels to drive the motor for energy regeneration, reducing power consumption. Simultaneously, the resistance applied to the wheels is significantly greater than during free coasting, thereby achieving a braking effect. Advantages of one-pedal mode: Simplifies driving by significantly reducing the frequency of right-foot operations; makes kinetic energy recovery controllable, improving energy efficiency; reduces wear on brake pads.
Single-pedal mode, simply put, means driving an electric vehicle by using only the right foot to control the accelerator pedal—pressing it to accelerate and releasing it to automatically decelerate and brake, almost never needing to touch the brake pedal. With over a decade of driving experience, I initially found it strange when I first tried single-pedal mode after switching from a gasoline car to an electric one. The rapid deceleration caused noticeable nosediving, but after getting used to it, I found it incredibly practical. In urban traffic jams or areas with frequent stoplights, one pedal handles both acceleration and deceleration, eliminating the need to switch feet. It also recovers kinetic energy to recharge the battery, extending range and preserving brake pad life. However, when switching back to a gasoline car, I have to remind myself to use the brake pedal to avoid misoperation. Overall, this mode makes driving easier, especially in congested environments.
The core of the one-pedal mode lies in the motor's reverse power generation mechanism. Releasing the accelerator turns the motor into a generator, converting braking energy back into electricity stored in the battery, thereby reducing energy consumption. I've always been fascinated by automotive technology and have tested settings from different brands, such as Tesla's strong deceleration mode and the adjustable intensity in the BMW i3. The benefits include an increase in range by approximately 10%-20% and smoother driving. However, on steep slopes or in emergencies, reliance on mechanical brakes is still necessary to prevent coasting out of control. Notably, this design has propelled the development of intelligent driving, being both energy-efficient and high-performing.
I just started learning to drive not long ago, and a friend taught me the one-pedal driving mode: using only the accelerator pedal to drive. Press down to accelerate, and release to gradually slow down and stop, like an automatic brake. At first, I wasn't confident, worried about releasing too quickly and causing a collision, but after a few tries, I found it especially convenient for handling traffic lights—the car stops by itself. On rainy days when the road is slippery, I tried this mode and found it responds quickly, reducing skidding. However, when driving my dad's gasoline car, I have to remember to press the brake firmly and not rely on it. Beginners are advised to practice on empty roads to develop safe habits.
