Method and device for operating a vehicle, and driving assistance system for a vehicle

1 . A method for operating a vehicle, comprising the following steps:

reading an occupant signal via an interface from at least one sensor apparatus of the vehicle, wherein the occupant signal represents a behavior of at least one vehicle occupant detected by the at least one sensor apparatus;

ascertaining a state signal using the occupant signal, wherein the state signal represents at least one state of attentiveness of the at least one vehicle occupant;

adapting at least one parameter of driving behavior planning for the vehicle, depending on the state signal, wherein in the adaptation step, a first parameter and a second parameter for a route for the vehicle planned using the driving behavior planning are adapted, wherein the first parameter represents a weighting of a duration of the planned route and the second parameter represents a number of alternative routes for the planned route;

determining a computing capacity required for the adapted driving behavior planning to generate a capacity signal that represents a free computing capacity which corresponds to a difference between the required computing capacity and an overall available computing capacity; and

releasing the free computing capacity for executing a function of the vehicle, depending on the capacity signal.

2 . The method according to claim 1 , wherein, in the reading step, the occupant signal is read via the interface from: (i) a vehicle camera of the vehicle, and/or (ii) a position sensor of the vehicle, and/or (iii) an infotainment apparatus of the vehicle.

3 . The method according to claim 1 , wherein the occupant signal read in the reading step represents an arrangement of the at least one vehicle occupant in the vehicle.

4 . The method according to claim 1 , wherein the occupant signal read in the reading step represents: (i) a viewing direction of the at least one vehicle occupant and/or (ii) a use of at least one object by the at least one vehicle occupant in the vehicle.

5 . The method according to claim 1 , wherein, in the ascertainment step, an inattentive or attentive state of the at least one vehicle occupant is ascertained as the state of attentiveness, wherein the inattentive state is ascertained as a short-term inattentive state or a long-term inattentive state.

6 . The method according to claim 1 , wherein in the release step, the free computing capacity is released to control an infotainment apparatus.

7 . The method according to claim 1 , wherein in the release step, the free computing capacity is released to control a planning of trajectories within a driving path planned using the driving behavior planning.

8 . The method according to claim 1 , wherein the ascertainment step is carried out using a machine learning method.

9 . A device configured to operate a vehicle, the device configured to:

read an occupant signal via an interface from at least one sensor apparatus of the vehicle, wherein the occupant signal represents a behavior of at least one vehicle occupant detected by the at least one sensor apparatus;

ascertain a state signal using the occupant signal, wherein the state signal represents at least one state of attentiveness of the at least one vehicle occupant;

adapt at least one parameter of driving behavior planning for the vehicle, depending on the state signal, wherein in the adaptation step, a first parameter and a second parameter for a route for the vehicle planned using the driving behavior planning are adapted, wherein the first parameter represents a weighting of a duration of the planned route and the second parameter represents a number of alternative routes for the planned route;

determine a computing capacity required for the adapted driving behavior planning to generate a capacity signal that represents a free computing capacity which corresponds to a difference between the required computing capacity and an overall available computing capacity; and

release the free computing capacity for executing a function of the vehicle, depending on the capacity signal.

10 . A non-transitory machine-readable storage medium on which is stored a computer program for operating a vehicle, the computer program, when executed by a computer, causing the computer to perform the following steps:

reading an occupant signal via an interface from at least one sensor apparatus of the vehicle, wherein the occupant signal represents a behavior of at least one vehicle occupant detected by the at least one sensor apparatus;

ascertaining a state signal using the occupant signal, wherein the state signal represents at least one state of attentiveness of the at least one vehicle occupant;

adapting at least one parameter of driving behavior planning for the vehicle, depending on the state signal, wherein in the adaptation step, a first parameter and a second parameter for a route for the vehicle planned using the driving behavior planning are adapted, wherein the first parameter represents a weighting of a duration of the planned route and the second parameter represents a number of alternative routes for the planned route;

determining a computing capacity required for the adapted driving behavior planning to generate a capacity signal that represents a free computing capacity which corresponds to a difference between the required computing capacity and an overall available computing capacity; and

releasing the free computing capacity for executing a function of the vehicle, depending on the capacity signal.
