The disclosure relates to a method for operating a brake pedal unit of a vehicle, comprising feedback to a driver. The brake pedal unit has a multiplicity of pressure-sensitive or force-sensitive sensors. According to the disclosure, in the method, output signals of the multiplicity of pressure-sensitive or force-sensitive sensors are detected. At least one position and/or an orientation of the operator's foot relative to the foot support element is determined from the detected output signals. A feedback signal that characterizes the determined position and/or orientation is output at an output unit of the vehicle.
