- a logic 330 is provided for the calculation of the first requirement value 01 and the second requirement value 02 .

Aspects of the calculation of the first requirement value 01 and the second requirement value 02 in the method, in particular aspects of the logic 330, are shown in FIG.
- a deviation D between the target value T4 for influencing the behavior of the steering gear actuator 112 and the target value T2 for the behavior of the steering gear actuator 112 is determined in a step 402 .
- This target value T4 is specified by function 320 in the example.
- the deviation D is a normalized difference between these target values and has values between 0 and 1 in the example.
- the deviation D can also be determined as a function of the state Z1.
- a step 404 at least one component for determining the first requirement value 01 and/or the second requirement value 02 as a function of the deviation D is determined.
- the first requirement value 01 and the second requirement value 02 are then determined as a function of at least one of these components.
- the target value T3 for the control element actuator 110 is determined as a function of the function 320 and the first requirement value 01 is determined as a function of a sum S of the target value T3 for the control element actuator 110 with a first component K1 that is independent of the deviation D.
- the first component K1 is an internal steering wheel angle requirement value. This can be applied to take a specific steering wheel behavior into account. As a result, in certain situations, for example when the driver suddenly lets go of the steering wheel 200 with a large steering angle, a slow turning back of the steering wheel 200 can be parameterized.
- the first component K1 can also be zero.
- the first requirement value 01 is determined as a function of a product P1 of the sum S with a second component K2 that changes as a function of the deviation D.
- the component K2 is a function of the deviation D in the example Steering wheel behavior or steering feel be parameterized. For example, when the deviation D increases, the function can lead to decreasing values of the component K2. Since this change acts at steering wheel level, ie influences steering wheel behavior or steering feel, and does not ensure that the driver has access to the steerable wheels, steering wheel behavior or steering feel can be parameterized by a variety of different functions.
- the sum S is a raw value for a steering wheel angle request value.
- the second component K2 is a factor with which the raw value is weighted.
- the second component K2 decreases as the deviation D increases.
- the target value T3 for the control element actuator 110 is therefore only corrected by the steering wheel angle request value.
- the second component K2 is determined, for example, as a function of an applicable characteristic curve that maps the deviation D to a value for the second component K2. This defines a behavior of the steering wheel 200 in the direction of the angle specified by the function.
- Figure 5 shows an exemplary parameterization for the second component K2.
- the second requirement value O2 is determined as a function of a product P2 of the target value T2 for the behavior of the steering gear actuator with a third component K3 that changes as a function of the deviation D.
- the third component K3 is a function of the deviation D.
- the parameters for the third component K3 can decrease as the deviation D increases.
- the third component K3 is a compensation value for the target value T2 for the behavior of the steering gear actuator.
- the third component K3 decreases as the deviation D increases. This means that if the deviation D is large, the driver's specification V1 is taken into account to a greater extent.
- the second requirement value 02 is determined depending on a difference D between this product P2 and the target value T4 for influencing the behavior of the steering gear actuator 112 .
- the second requirement value 02 is determined as a function of a product P3 of the difference D with a fourth component K4 that changes as a function of the deviation D.
- the fourth component K4 is a factor with which the difference between the target value T4 for influencing the behavior of the steering gear actuator 112 and the target value T2 for the behavior of the steering gear actuator is taken into account.
- the fourth component K4 decreases as the deviation D increases.
- the fourth component K4 is determined, for example, as a function of an applicable characteristic curve that maps the deviation D to a value for the fourth component K4. This applies the manner in which the driver regains control when their intent differs from that of the function. As a result, for example, an extent of the deviation D is applied from which the driver regains access to the steered wheels. This parameterizes, for example, a speed at which control is regained.
- Figure 6 shows an exemplary parameterization for the fourth component K4.
- step 404 it can be provided that the input E1 is recorded.
- the control element actuator 110 is controlled as a function of the first requirement value 01 and the steering gear actuator 112 is controlled independently of the second requirement value 02.
- the second component K2 is determined to be different from zero.
- the first requirement value 01 is therefore not equal to zero.
- the control element actuator 110 is activated depending on the first requirement value 01.
- the fourth component K4 is determined to be zero.
- the second requirement value 02 is thus zero.
- the steering gear actuator is activated independently of the second requirement value 02.
- the first operating mode is parameterized in particular by the selection of the components in such a way that a driver input via the steering wheel acts directly or synchronously on the set angle on the steerable wheels of the vehicle and the function, for example for lane assistance in this operating mode, only influences the steering wheel behavior in order to influence vehicle behavior.
- the second component K2 is determined in such a way that the second component K2 is different from zero.
- the fourth component K4 is determined in such a way that the fourth component K4 is permanently set to zero.
- control element actuator 110 can be activated at least temporarily as a function of first requirement value 01 and steering gear actuator 112 at least temporarily as a function of second requirement value 02.
- the second component K2 is determined in such a way that the second component K2 is at least temporarily different from zero.
- the fourth component K4 is determined in such a way that the fourth component K4 differs from zero at least at times.
- the second operating mode is a comfort mode in the example.
- the function can provide a threshold value for lane assistance, for example, which defines a range within which the function can change the angle of the vehicle set on the steerable wheels independently of the driver, without feedback being given to the driver via the steering wheel .
- This parameter can be applied in the example.
- the components are parameterized in such a way that the driver slowly regains the coupling to the angle set for the steerable wheels when an intervention in the function is ended. For example, by cross winds or inclined Roadside-related wheel steering angle corrections can thus be carried out conveniently without feedback to the driver on the steering wheel.
- the steering wheel angle on the steering wheel 200 remains static in the desired position of 0°, for example. If the driver takes over lateral vehicle control again, i.e. the driver makes an input that differs from the desired steering wheel position, in this operating mode the penetration of the function on the steerable wheels is gradually faded out, so that the driver gradually takes over the vehicle lateral control via the steerable wheels given angle.
- steps 402 and 404 are executed repeatedly during operation of the vehicle.
- the steering system can be a steer-by-wire system that has two separate interfaces: an interface for the control element actuator 110 and an interface for the steering gear actuator 112.
- the function can be implemented particularly well, especially in contrast to an interface for a request value for a torsion of a torsion bar or for a demand value for a torque of a drive for the steering gear or for a demand value for a gear position of the steering gear.
