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. ## Claims ### Claim 1 A method for setting a driving speed of a motor vehicle on a route, wherein 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, comprising: detecting the operating position of the pedal device; depending on the detected operating position and in at least one specified driving mode, determining a target driving speed corresponding to the respective operating position; and controlling the driving speed corresponding to the respective target driving speed using a closed loop control as long as the respective operating position is detected independent of a current condition of the route; wherein the target driving speed is increased when the operating position changes toward a first of the extreme positions, and the target driving speed is reduced when the operating position changes toward a second of the extreme positions. ### Claim 2 (depends on 1) The method of claim 1, wherein a single vehicle pedal of the motor vehicle is used as the pedal device, wherein the extreme positions each correspond to a target driving speed predetermined by the driving mode. ### Claim 3 (depends on 1) The method of claim 1, wherein an acceleration pedal is used as the pedal device, and a change in an operating position of the acceleration pedal from an unoperated extreme position into a fully depressed extreme position corresponds to an increase in the target driving speed; and/or a brake pedal is used as the pedal device, and a change in its operating position from an unoperated extreme position into a fully depressed extreme position corresponds to a reduction of the target driving speed. ### Claim 4 (depends on 1) The method of claim 1, wherein the target driving speed is ascertained by the operating position of the pedal device in combination with a predetermined pedal characteristic curve of the pedal device. ### Claim 5 (depends on 4) The method of claim 4, wherein a nonlinear pedal characteristic curve is used as the pedal characteristic curve, and/or the pedal characteristic curve is selected and/or defined by a user. ### Claim 6 (depends on 4) The method of claim 4, wherein the pedal characteristic curve is set at least relative to an effect of a change of the operating position on a change of the target driving speed depending on one or more of the driving speed and a current gear ratio. ### Claim 7 (depends on 4) The method of claim 4, wherein the control device changes the predetermined pedal characteristic curve when a kickdown of the pedal device is detected, or another predetermined pedal characteristic curve is used to determine the target driving speed after the kickdown. ### Claim 8 (depends on 4) The method of claim 4, wherein the control device selects the predetermined pedal characteristic curve at least depending on a weather situation that is ascertained by the control device depending on weather data characterizing the weather situation. ### Claim 9 (depends on 8) The method of claim 8, wherein the control device receives the weather data at least from an external higher-level computing apparatus through a radio link. ### Claim 10 (depends on 8) The method of claim 8, wherein the control device receives the weather data at least from a vehicle component of the motor vehicle. ### Claim 11 (depends on 10) The method of claim 10, wherein the vehicle component is a sensor apparatus, or a windshield wiper apparatus, or a headlamp apparatus. ### Claim 12 (depends on 4) The method of claim 4, wherein the control device selects the predetermined pedal characteristic curve at least depending on a traffic situation of the motor vehicle that is ascertained by the control device depending on the traffic data characterizing the traffic situation of the motor vehicle. ### Claim 13 (depends on 12) The method of claim 12, wherein the control device receives the traffic data at least from the external higher-level computing apparatus through a radio link. ### Claim 14 (depends on 12) The method of claim 12, wherein the control device receives the traffic data at least from a sensor apparatus. ### Claim 15 (depends on 4) The method of claim 4, wherein the control device selects the predetermined pedal characteristic curve at least depending on a speed default that is ascertained by the control device depending on speed data characterizing the speed default. ### Claim 16 (depends on 15) The method of claim 15, wherein the control device receives the speed data at least from the external higher-level computing apparatus through a radio link. ### Claim 17 (depends on 15) The method of claim 15, wherein the control device receives the speed data at least from a vehicle component of the motor vehicle. ### Claim 18 (depends on 17) The method of claim 17, wherein the vehicle component is a sensor apparatus or a navigation system. ### Claim 19 (depends on 1) The method of claim 1, wherein the predetermined driving mode is one or more of cross-country driving and driving or maneuvering the motor vehicle with a trailer coupled to the vehicle. ### Claim 20 A motor vehicle with a pedal device and a control device for setting a driving speed of the motor vehicle corresponding to an operating position of the pedal device, wherein the control device is configured for: detecting the operating position of the pedal device; depending on the detected operating position and in at least one specified driving mode, determining a target driving speed corresponding to the respective operating position; and controlling the driving speed corresponding to the respective target driving speed using a closed loop control as long as the respective operating position is detected independent of a current condition of a route; wherein the target driving speed is increased when the operating position changes toward a first extreme position of the pedal device, and the target driving speed is reduced when the operating position changes toward a second extreme position of the pedal device. ### Claim 21 A method for setting a driving speed of a motor vehicle on a route, wherein 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, comprising: detecting the operating position of the pedal device; depending on the detected operating position and in at least one specified driving mode, determining a target driving speed corresponding to the respective operating position; and controlling the driving speed corresponding to the respective target driving speed using a closed loop control as long as the respective operating position is detected independent of a current condition of the route; wherein a single vehicle pedal of the motor vehicle is used as the pedal device, wherein the extreme positions each correspond to a target driving speed predetermined by the driving mode.
