Abstract

What is described is a motor vehicle ignition key and a method including a movement sensor for detecting the movement of the motor vehicle ignition key, a motor vehicle navigation device, and a method including a calculator for calculating a driving route in dependence of movement data, and a motor vehicle system and a method including a motor vehicle ignition key and a motor vehicle controller.

Claims

1. A motor vehicle ignition key comprising:

a movement sensor for detecting a movement of the motor vehicle ignition key;

a memory for recording the movement data acquired from the detected movement; and

an interface for outputting the movement data to an external unit.

2. The motor vehicle ignition key as claimed in claim 1,

wherein the movement sensor comprises a 3D acceleration sensor;

or

wherein the movement sensor comprises a 3D acceleration sensor and a pressure sensor for altitude detection.

3. The motor vehicle ignition key as claimed in claim 1,

further comprising an evaluator;

the evaluator being configured to generate, from the raw data provided by the movement sensor, classified activity information as the movement data.

4. The motor vehicle ignition key as claimed in claim 1,

further comprising a device for displaying a presentation of the movement data to a user.

5. A method comprising:

a) detecting the movement of a motor vehicle ignition key by a movement sensor within the motor vehicle ignition key;

b) recording the movement data acquired from the detected movement into a memory of the motor vehicle ignition key; and

c) outputting the movement data to an external unit.

7. The motor vehicle navigation device as claimed in claim 5,

wherein the calculator for calculating the driving route is configured to propose to the motor vehicle user, in dependence on the movement data, a destination in the vicinity of or at a distance from a destination desired by the motor vehicle user, so that the motor vehicle user may cover a distance to reach the desired destination;

and/or

to propose to the motor vehicle user sport activities offered in the area; and

/or

to propose to the motor vehicle user a walk instead of a driving route to the desired destination.

6. A motor vehicle navigation device comprising:

an interface for receiving movement data of a motor vehicle user that is detected by an external sensor worn on the body; and

a calculator for calculating a driving route while taking into account the movement data.

8. A method comprising:

a) receiving movement data, captured by an external sensor, of a motor vehicle user by means of an interface of a motor vehicle navigation device;

b) calculating a driving route using a unit of the motor vehicle navigation device while taking into account the received movement data.

9. A motor vehicle system comprising:

a motor vehicle ignition key comprising a movement sensor for detecting a movement of the motor vehicle ignition key, the motor vehicle ignition key comprising a memory for recording the movement data acquired from the detected movement, and a first interface for outputting the movement data to a motor vehicle controller; and

a motor vehicle controller associated with the motor vehicle ignition key, comprising a second interface for receiving the movement data and for performing motor vehicle control tasks.

10. The motor vehicle system as claimed in claim 9,

wherein the motor vehicle controller is configured to vary a strength of the power steering in dependence on the movement data received;

and/or to deactivate a start-up function of the car.

11. The motor vehicle system as claimed in claim 9;

further comprising a charging device, and wherein the motor vehicle ignition key comprises a rechargeable energy store, the charging device being adapted to charge the energy store of the motor vehicle ignition key.

12. The motor vehicle system as claimed in claim 9,

further comprising an ignition key readout device,

the ignition key readout device being configured to transmit the movement data from the motor vehicle ignition key to an external unit.

13. The motor vehicle system as claimed in claim 9,

comprising a plurality of motor vehicle ignition keys, each motor vehicle ignition key having unambiguously associated therewith an index from the plurality of motor vehicle ignition keys;

and

wherein the motor vehicle controller is adapted to perform motor vehicle control tasks while taking into account the movement data and the index.

14. A method comprising:

a) detecting the movement of a motor vehicle ignition key using a movement sensor within the motor vehicle ignition key;

b) recording the movement data acquired from the movement;

c) outputting the movement data from the motor vehicle ignition key, and reception of the movement data on the part of a motor vehicle controller;

d) performing motor vehicle control tasks while taking into account the movement data.

15. A non-transitory computer readable medium including a computer program for performing, when the computer program is executed on a processor, a method comprising the steps of:

a) detecting the movement of a motor vehicle ignition key by a movement sensor within the motor vehicle ignition key;

b) recording the movement data acquired from the detected movement into a memory of the motor vehicle ignition key; and

c) outputting the movement data to an external unit.

16. A non-transitory computer readable medium including a computer program for performing, when the computer program is executed on a processor, a method comprising the steps of:

a) receiving movement data, captured by an external sensor, of a motor vehicle user by means of an interface of a motor vehicle navigation device;

b) calculating a driving route using a unit of the motor vehicle navigation device while taking into account the received movement data.

17. A non-transitory computer readable medium including a computer program for performing, when the computer program is executed on a processor, a method comprising the steps of:

a) detecting the movement of a motor vehicle ignition key using a movement sensor within the motor vehicle ignition key;

b) recording the movement data acquired from the movement;

c) outputting the movement data from the motor vehicle ignition key, and reception of the movement data on the part of a motor vehicle controller;

d) performing motor vehicle control tasks while taking into account the movement data.
