Abstract

A warning system of a vehicle is provided. The warning system includes a haptic warning signaler, a control module, and a haptic sensor. The haptic warning signaler is associated with the haptic sensor for recording a haptic receptiveness. For a traffic or operating situation of the vehicle ranked as critical, the control module activates the haptic warning signaler if the haptic sensor signals a haptic receptiveness to the control module. A method for warning occupants of a vehicle also is provided.

Claims

1. A warning system of a vehicle, the warning system comprising:

a haptic warning signaler;

a control module, and

a haptic sensor,

wherein the haptic warning signaler is associated with the haptic sensor for recording a haptic receptiveness, and wherein for a traffic or operating situation of the vehicle ranked as critical, the control module activates the haptic warning signaler if the haptic sensor signals a haptic receptiveness to the control module.

2. The warning system according to claim 1, wherein the control module automatically activates a warning signaler other than a haptic warning signaler if there is no haptic receptiveness or if despite a signaled haptic receptiveness no measure for avoiding a traffic or operating situation ranked as critical is ascertained by the control module.

3. The warning system according to claim 1, wherein a contact sensor is integrated with the haptic warning signaler which is operatively connected with the control module.

4. The warning system according to claim 3, wherein the control module comprises a contact detecting module that interacts with the contact sensor of the haptic warning signaler.

5. The warning system according to claim 1, wherein the control module comprises a decision signaling module that interacts with several warning signalers.

6. The warning system according to claim 1, wherein the control module stepwise and automatically activates, starting at a lower warning stage, a next higher warning stage in case no measure for avoiding the traffic or operating situation ranked as critical is ascertained.

7. The warning system according to claim 1, wherein the warning system further comprises an optical warning signaler and an acoustic warning signaler, and wherein for a traffic or operating situation of the vehicle ranked as critical, the haptic, optical and acoustic warning signalers are activated in stages with the optical warning signaler as the first warning stage, the haptic warning signaler as the second warning stage, the acoustic warning signaler as the third warning stage and all warning signalers simultaneously as the highest warning stage, by the control module.

8. A motor vehicle comprising:

a warning system comprising;

a haptic warning signaler;

a control module, and

a haptic sensor,

wherein the haptic warning signaler is associated with the haptic sensor for recording a haptic receptiveness, and wherein for a traffic or operating situation of the vehicle ranked as critical, the control module activates the haptic warning signaler if the haptic sensor signals a haptic receptiveness to the control module, and

an environment sensor that is operatively connected with the control module of the warning system.

9. The motor vehicle according to claim 8, wherein the motor vehicle further comprises a passenger compartment monitoring sensor that is operatively connected with the control module.

10. The motor vehicle according to claim 8, wherein the control module comprises a danger detecting module which interacts with the environment sensor of the motor vehicle.

11. A method for warning occupants of a vehicle which comprises a haptic warning signaler and a control module, wherein the method comprises the steps of:

ranking a traffic or operating situation of the vehicle as critical;

checking whether a signal of a haptic receptiveness of the vehicle is signaled to the control module by a sensor associated with the haptic warning signaler;

if yes, activating the haptic warning signaler;

if no, activating a further warning signaler;

if no measure for avoiding the critical traffic or operating situation of the vehicle is taken, activating a driver assistance system.

12. The method according to claim 11, wherein activating the respective warning signaler is terminated if a measure for avoiding the traffic or operating situation ranked as critical is taken.

13. The method according to claim 11, wherein additionally or alternatively to the haptic warning signaler an optical or an acoustic warning signaler is activated.

14. The method according to claim 13, wherein in a traffic or operating situation ranked as most dangerous the optical, the haptic and the acoustic warning signaler are simultaneously activated.

15. A method for warning occupants of a vehicle by an optical, a haptic or an acoustic warning signaler, wherein the method comprises the steps of:

ranking a traffic or operating situation as critical;

activating the optical warning signaler as a first warning stage,

activating the haptic warning signaler as the second warning state in case no measure for avoiding the traffic or operating situation ranked as critical is taken;

activating the acoustic warning signaler as the third warning stage in case it is detected that the haptic warning signaler is not touched or, despite touching, no measure for avoiding the traffic or operating situation ranked as critical is taken;

activating all three warning signalers together as the highest warning stage, and

activating an automatic driver assistance system in case of extreme danger.
