Control of a user equipment based on in-vehicle position

1. A user equipment, comprising:

a positioning unit configured to determine a relative position of the user equipment within a reference coordinate system that is defined with respect to a vehicle; and

a processor configured to:

execute an application that provides one or more features associated with at least one of in-vehicle entertainment and in-vehicle control to a user of the user equipment, and

when executing the application, selectively enable or disable user access to at least one feature of the application based on the relative position of the user equipment, wherein the at least one feature relates to at least one of vehicle entertainment or vehicle control.

2. The user equipment of claim 1 , wherein the positioning unit is configured to determine the relative position of the user equipment by determining a signal strength of an electromagnetic field emitted by a transceiver associated with the vehicle.

3. The user equipment of claim 2 , wherein the positioning unit is configured to determine the relative position based on signal strengths of at least two electromagnetic fields emitted by at least two transceivers associated with the vehicle and signal phases associated with the at least two electromagnetic fields.

4. The user equipment of claim 1 , wherein the positioning unit is configured to determine the relative position of the user equipment based on control data received via a data connection established between the user equipment and a transceiver associated with the vehicle, the control data indicating an occupancy of seating positions of the vehicle.

5. The user equipment of claim 1 , wherein the positioning unit is configured to determine the relative position of the user equipment by determining the presence of a fixed line connection between the user equipment and an interface associated with the vehicle.

6. The user equipment of claim 1 , wherein the positioning unit is configured to determine the relative position of the user equipment by determining an acceleration associated with the user equipment relative to an acceleration associated with the vehicle.

7. The user equipment of claim 1 , wherein the positioning unit is configured to determine the relative position of the user equipment by establishing a wireless connection with a near-field communications transceiver associated with the vehicle.

8. The user equipment of claim 1 , wherein the positioning unit is configured to determine the relative position of the user equipment by receiving invisible or visible optical signals from a transceiver associated with the vehicle.

9. The user equipment of claim 1 , wherein the processor is further configured to select and display a graphical user interface associated with the application based on the relative position of the user equipment.

10. The user equipment of claim 1 , wherein the processor is further configured to selectively enable or disable user access to at least one feature of the application based on access permissions assigned to a user according to the relative position of the user equipment.

11. The user equipment of claim 10 , wherein the access permissions assigned to a user located in a driver seat of the vehicle include at least one of:

features relevant to navigating the vehicle, including at least one of route planning, route guidance, and range estimation,

features related to traffic awareness, including at least one of traffic messages, detour planning, and traffic delays,

features related to vehicle and passenger safety, including at least one of emergency functions, locking doors, and a panic button,

features relevant to vehicle control, including at least one of in-vehicle climate control, engine and gear control, and lighting control, and

features relevant to communications, including at least one of call setup and internet access.

12. The user equipment of claim 10 , wherein the access permissions of a user located in a rear seat of the vehicle include at least one of features relevant to rear-seat entertainment, and features relevant to communications, including at least one of call setup and internet access.

13. The user equipment of claim 10 , wherein the access permissions of a user located outside the vehicle include at least one of vehicle access, including at least one of locking and unlocking doors, opening and closing doors, and emergency lock down, and in-vehicle climate control.

14. The user equipment of claim 1 , wherein the positioning unit is configured to determine the relative position of the user equipment according to seating positions defined within the vehicle.

15. A method of controlling operation of a user equipment positioned in a reference coordinate system that is defined with respect to a vehicle, the method comprising:

determining a relative position of the user equipment within the reference coordinate system;

executing an application that provides one or more features associated with at least one of in-vehicle entertainment and in-vehicle control to a user of the user equipment; and

selectively enabling or disabling user access to at least one feature of the application based on the relative position of the user equipment, wherein the at least one feature relates to at least one of vehicle entertainment or vehicle control.
