Abstract

A vehicle includes at least one main sensor unit, the measurement signal of which is characteristic of a main driver desire of a vehicle occupant with regard to an influence on the driving behavior of the vehicle, and at least one secondary sensor unit, the measurement signal of which is characteristic of a secondary driver desire. The main driver desire is represented by a motion of a hand or a foot of the vehicle occupant. The secondary driver desire is represented in a manner other than by the motion of the hand or the foot of the vehicle occupant. The vehicle also has at least one actuator. The actuator influences the driving behavior of the vehicle in dependence on a control signal. A resulting driver desire with regard to the influence on the driving behavior of the vehicle is determined in dependence on the main driver desire and in dependence on the secondary driver desire. In the case of a neutral value of the main driver desire, the secondary driver desire is assigned to the resulting driver desire. Otherwise, the main driver desire is assigned to the resulting driver desire. The control signal is produced in dependence on the resulting driver desire.

Claims

1. A method for operating a vehicle equipped with:

at least one main sensor unit whose measurement signal is characteristic of a main driver'"'"'s request of a vehicle occupant with respect to influencing of a driving behavior of the vehicle, represented by a movement of a hand or a foot of the vehicle occupant,

at least one secondary sensor unit whose measurement signal is characteristic of a secondary driver'"'"'s request of the vehicle occupant with respect to influencing of the driving behavior of the vehicle, represented other than by the movement of the hand or the foot of the vehicle occupant, and

at least one actuator which influences the driving behavior of the vehicle as a function of an actuation signal,

wherein the method comprises the acts of;

as a function of the main driver'"'"'s request represented by he measurement signal of the main sensor and as a function of the secondary driver'"'"'s request represented by the measurement signal of the secondary sensor, determining a resulting driver'"'"'s request with respect to the influencing of the driving behavior of the vehicle;

in a case of a neutral value of the main driver'"'"'s request, assigning the secondary driver'"'"'s request to the resulting driver'"'"'s request and, otherwise, assigning the main driver'"'"'s request to the resulting driver'"'"'s request; and

generating the actuation signal as a function of the resulting driver'"'"'s request.

2. The method according to claim 1, wherein the main sensor unit is embodied as a pressure sensor and/or a torque sensor.

3. The method according to claim 1, wherein the main sensor unit is embodied as a contact sensor unit and/or a proximity sensor unit.

4. The method according to claim 1, wherein the main sensor unit is embodied as an image-processing main sensor unit.

5. The method according to claim 1, wherein the secondary sensor unit is embodied as an image-processing secondary sensor unit.

6. The method according to claim 5, wherein the secondary driver'"'"'s request is represented by a viewing direction of the vehicle occupant within a predefined region.

7. The method according to claim 1, wherein the secondary sensor unit is embodied as an audio signal-processing unit.

8. The method according to claim 7, wherein the secondary driver'"'"'s request is represented by a voice command of the vehicle occupant.

9. The method according to claim 1, wherein the secondary sensor unit is embodied as an electro-encephalograph.

10. The method according to claim 9, wherein the secondary driver'"'"'s request is represented by electrical brain activity of the vehicle occupant.

11. The method according to claim 1, wherein:

a destination specification of the vehicle occupant is made available,

data relating to a surrounding area of the vehicle is made available,

the actuation signal is generated as a function of the destination specification of the vehicle occupant and of the data relating to the surrounding area of the vehicle and of the resulting driver'"'"'s request of the vehicle occupant.

12. A vehicle control system, comprising:

at least one main sensor unit whose measurement signal is characteristic of a main driver'"'"'s request of a vehicle occupant with respect to influencing of a driving behavior of the vehicle, represented by a movement of a hand or a foot of the vehicle occupant;

at least one secondary sensor unit whose measurement signal is characteristic of a secondary driver'"'"'s request of the vehicle occupant with respect to influencing of the driving behavior of the vehicle, represented other than by the movement of the hand or the foot of the vehicle occupant;

at least one actuator which influences the driving behavior of the vehicle as a function of an actuation signal; and

a device for operating the vehicle, the device being coupled via signaling technology to the main sensor unit, the secondary sensor unit, and the actuator, wherein the device comprises a processor and associated memory storing program code which, when executed, causes the processor to;

as a function of the main driver'"'"'s request represented by the measurement signal of the main sensor and as a function of the secondary driver'"'"'s request represented by the measurement signal of the secondary sensor, determine a resulting driver'"'"'s request with respect to the influencing of the driving behavior of the vehicle;

in a case of a neutral value of the main driver'"'"'s request, assign the secondary driver'"'"'s request to the resulting driver'"'"'s request and, otherwise, assigning the main driver'"'"'s request to the resulting driver'"'"'s request; and

generate the actuation signal as a function of the resulting driver'"'"'s request.

13. A computer program product comprising a non-transitory computer readable medium having stored thereon program code which, when executed in a vehicle equipped with:

at least one main sensor unit whose measurement signal is characteristic of a main driver'"'"'s request of a vehicle occupant with respect to influencing of a driving behavior of the vehicle, represented by a movement of a hand or a foot of the vehicle occupant,

at least one secondary sensor unit whose measurement signal is characteristic of a secondary driver'"'"'s request of the vehicle occupant with respect to influencing of the driving behavior of the vehicle, represented other than by the movement of the hand or the foot of the vehicle occupant, and

at least one actuator which influences the driving behavior of the vehicle as a function of an actuation signal,

carries out the acts of;

as a function of the main driver'"'"'s request represented by the measurement signal of the main sensor and as a function of the secondary driver'"'"'s request represented by the measurement signal of the secondary sensor, determining a resulting driver'"'"'s request with respect to the influencing of the driving behavior of the vehicle;

in a case of a neutral value of the main driver'"'"'s request, assigning the secondary driver'"'"'s request to the resulting driver'"'"'s request and, otherwise, assigning the main driver'"'"'s request to the resulting driver'"'"'s request; and

generating the actuation signal as a function of the resulting driver'"'"'s request.
