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 system comprising:

a movement sensor arranged to be worn or carried by a motor vehicle user and configured to detect a movement of the motor vehicle user, the movement sensor comprising a memory configured to record the movement data acquired from the detected movement and a first interface configured to output the movement data to a motor vehicle controller; and

a motor vehicle controller comprising a second interface configured to receive the movement data and to perform motor vehicle control tasks according to the movement data.

2. The motor vehicle system as claimed in claim 1,

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.

3. The motor vehicle system as claimed in claim 1, wherein the movement sensor is integrated into a motor vehicle ignition key of the motor vehicle system.

4. The motor vehicle system as claimed in claim 3;

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.

5. The motor vehicle system as claimed in claim 3,

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.

6. The motor vehicle system as claimed in claim 3,

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.

7. A method comprising:

a) detecting a movement of a motor vehicle user using a movement sensor worn or carried by the motor vehicle user;

b) recording, by a memory, movement data based on the detected movement of the motor vehicle user;

c) outputting, by an intelligent system, the movement data from the memory;

d) performing, using a processor, motor vehicle control tasks according to the movement data;

wherein

the movement data output by the intelligent system is received by a motor vehicle controller.

8. The method as claimed in claim 7, wherein the movement sensor is integrated into a motor vehicle ignition key of the motor vehicle system.

9. 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 a movement of a motor vehicle user using a movement sensor worn or carried by the motor vehicle user;

b) recording movement data based on the detected movement of the motor vehicle user;

c) outputting the movement data, and receiving the movement data by a motor vehicle controller;

d) performing motor vehicle control tasks according to the movement data.

10. The non-transitory computer readable medium as claimed in claim 9, wherein the movement sensor is integrated into a motor vehicle ignition key of the motor vehicle system.
