A vehicle includes a powertrain having an electric machine configured to power driven wheels, an accelerator pedal, and friction brakes. A vehicle controller is programmed to, with the vehicle being in a one-pedal driving mode: in response to a braking torque capacity of the powertrain exceeding a target braking torque that is based on a position of the accelerator pedal, command a torque, that is equal to the target braking torque, from the powertrain such that the vehicle is slowed using the powertrain without application of the friction brakes, and, in response to the braking torque capacity of the powertrain being less than the target braking torque, command torques from the powertrain and the friction brakes such that the target braking torque is satisfied and the vehicle is slowed using the powertrain and the friction brakes.
