One Pedal Drive

WARNING: This page is about a different car, the 2022 Ford E-Transit. However, it is still accessible from the selected car via links, so may be relevant.

One Pedal Drive allows the driver to both accelerate (motor propulsion torque) and decelerate (regeneration motor torque) using the accelerator pedal. Under most driving conditions it reduces the need to use the brake pedal to slow and stop the vehicle.

Pressing the accelerator pedal down accelerates the vehicle. Releasing pressure on the accelerator pedal with the foot still on the pedal slows down the vehicle. Lifting the driver's foot entirely off the pedal allows the vehicle to come to a complete stop on flat ground and mild slopes. The brake pedal still functions as normal if needed for quicker stopping.

The PCM monitors the pedal position and determines the powertrain torque request for either motor propulsion torque or motor regenerative braking torque. The torque request is sent to both the Inverter System Controller (ISC) and the ABS. The ISC determines the final motor torque, controls the vehicle to a stop at closed pedal, and makes requests for autonomous braking to the ABS as needed. The ABS fills in any brake torque requested by the PCM that the ISC cannot achieve by motor torque with friction brake torque. The ABS also performs an automated brake stop or applies standstill braking torque when requested by the ISC.
