5. The device as claimed in claim 1 , wherein the second condition includes a control-resumption request regarding the longitudinal guidance of the vehicle to be carried out by the driver, which is detected by the vehicle.

6. The device as claimed in claim 1 , wherein the second condition includes a control-resumption request regarding lateral guidance of the vehicle to be carried out by the driver of the vehicle, including at least one of a readiness of steering and a steering action.

7. The device as claimed in claim 1 , wherein the second condition is a recognition of at least one of willingness and capability by the driver to take over a driving task.

8. The device as claimed in claim 1 , wherein at least one of the first condition and the second condition is dependent on at least one of a necessity and a handling recommendation to carry out a particular maneuver as determined by the vehicle.

9. The device as claimed in claim 1 , wherein at least one of the first condition and the second condition is dependent on one or more of the following parameters determined by the vehicle:

attention status, viewing direction, and sight accommodation of the driver;

driver status detection, including alertness status, sleeping status, blinking detection, and microsleep status of the driver.

10. The device as claimed in claim 1 , wherein at least one of the first condition and the second condition is detected by a sensor in a mobile user device and provided to a computing unit of the mobile user device.

11. The device as claimed in claim 1 , wherein the blocking of the first actuation element is stageless, wherein a parameter of the blocking is dependent on at least one of a qualitative and a quantitative parameter of the first condition.

12. The device as claimed in claim 1 , wherein the predefined position limits for an automated driving mode of the vehicle are different from further position limits that are defined for at least partly manual driving.

13. The device as claimed in claim 12 , wherein at least one of the predefined position limits is dependent on one or more of the following criteria:

a degree of automation relevant to a current drive;

a velocity range relevant to the current drive;

a current seat position or seat setting of the driver;

a body position or pose of the driver;

the driver;

an alertness state of the driver.

14. The device as claimed in claim 12 , wherein the predefined position limits are selected in terms of at least one of their angles and positions such that they are located between a first position range, which brings about an acceleration of the vehicle in an at least partly manual driving mode of the vehicle, and a second position range, which brings about a deceleration of the vehicle in the at least partly manual driving mode of the vehicle.

15. An apparatus configured to provide at least partly automated driving of a vehicle, the apparatus comprising:

a pedal module including an actuation element configured to control longitudinal guidance by a driver, wherein the actuation element is blocked within predefined position limits in accordance with a variable representing a degree of automation of driving of the vehicle and in accordance with a first condition, and

a processor configured to output a control signal for blocking of the actuation element,

wherein the blocking of the actuation element is suspended in accordance with the variable representing the degree of automation of the driving of the vehicle and a second condition, and

wherein the first condition includes a determination that the actuation element has not been actively actuated for a fixed time interval before a moment when the degree of automation is achieved.

16. A method for operating a vehicle that is configured to be driven in an at least partly automated manner, the vehicle including an actuation element configured to control longitudinal guidance of the vehicle by a driver, wherein the actuation element is blocked within predefined position limits in accordance with a variable representing a degree of automation of driving of the vehicle and in accordance with a first condition, wherein the first condition includes a determination that the actuation element has not been actively actuated for a fixed time interval before a moment when the degree of automation is achieved, wherein blocking of the actuation element is suspended in accordance with the variable representing the degree of automation of the driving of the vehicle and a second condition, the method comprising:

detecting the variable representing the degree of automation of the driving of the vehicle;

detecting fulfillment of at least one of the first condition and the second condition;

initiating the blocking of the actuation element for controlling the longitudinal guidance of the vehicle within the predefined position limits as a function of the variable representing the degree of automation of the driving of the vehicle and the first condition; and

initiating suspension of the blocking of the actuation element for controlling the longitudinal guidance of the vehicle as a function of the variable representing the degree of automation of the driving of the vehicle and the second condition.

17. A non-transitory computer-readable medium storing a computer program that is executable by a computer for operating an at least partly automated driving of a vehicle that is configured to be driven in an at least partly automated manner, the vehicle including an actuation element configured to control longitudinal guidance of the vehicle by a driver, wherein the actuation element is blocked within predefined position limits in accordance with a variable representing a degree of automation of driving of the vehicle and in accordance with a first condition, wherein the first condition includes a determination that the actuation element has not been actively actuated for a fixed time interval before a moment when the degree of automation is achieved, wherein blocking of the actuation element is suspended in accordance with the variable representing the degree of automation of the driving of the vehicle and a second condition, the computer when executing the computer program is configured to perform steps comprising:
