Abstract: The invention relates to a method for setting a driving speed of a motor vehicle on a route. A control device of the motor vehicle sets the driving speed depending on an operating position limited by two extreme positions of a pedal device of the motor vehicle, which may be operated by a driver, wherein the control device detects the operating position of the pedal device, and depending on the detected operating position, determines in at least one specified driving mode a target driving speed corresponding to the respective operating position, and the control device sets the driving speed corresponding to the respective target driving speed by means of a closed loop control as long as the respective operating position is detected. The setting in this case takes place independently of a current condition of the route. The invention also includes a motor vehicle.
