A vehicle includes a powertrain having an electric machine configured to power driven wheels and friction brakes. A vehicle controller is programmed to, with the vehicle being in a one-pedal driving mode and the friction brakes automatically engaged to hold the vehicle stationary, release the friction brakes absent input from a brake pedal in response to an estimated torque of the driven wheels exceeding a grade-compensation torque threshold that is based on road grade to launch the vehicle without rollback.
