One Pedal
This is a One Pedal Driving Dashboard Indicator symbol. One pedal driving is a feature of electric vehicles, where much of the braking is accomplished by the electric motor as the accelerator pedal is released. The brake pedal is not touched in most cases when the system is activated.
- Before moving on, is this truly your symbol??

This is part and parcel of Regenerative Braking, where the energy used to slow the vehicle is captured and returned to the the high voltage battery. There is a misconception that this accomplished through the vehicles brake system, which is simply not the case (I once listened to a dealership owner explain regenerative braking to a customer perfectly wrong!). In fact the electric motor reverses, which slows the vehicle a sends energy back to the battery.
From a driver’s perspective, regenerative braking turns out to be quite intuitive. The more the accelerator pedal is released, the harder the braking action. This is very similar to actual braking., where the more the brake pedal is pushed, the harder the braking action.
Emergency stops in an EV will still require the use of the brake pedal. But moment to moment driving can be accomplished with the accelerator pedal only. Most manufacturers allow the driver to choose the amount of braking action applied by the electric motor. One pedal driving is accomplished only at the highest setting.
