Electromagnetic joint for a vehicle
A vehicle system is disclosed herein. The vehicle includes a vehicle structure. A vehicle component is coupled to the vehicle structure via electromagnetic attraction. The controller is configured to generate a command to vary the amount of electromagnetic attraction between the vehicle structure and the vehicle component in response to a received vehicle threat signal.
1. A vehicle system, comprising:
a vehicle structure;
a vehicle component coupled to the vehicle structure via electromagnetic attraction;
an attachment feature that additionally couples the vehicle structure to the vehicle component;
a sensor configured to sense at least one of an expected vehicle impact event and a vehicle impact event; and
a controller configured to generate a command to vary the amount of electromagnetic attraction between the vehicle structure and the vehicle component in response to a received vehicle threat signal from the sensor indicating at least one of a sensed expected vehicle impact event and a sensed vehicle impact event, wherein the attachment feature is configured to yieldingly maintain the vehicle component in a use position relative to the vehicle structure, irrespective of the amount of electromagnetic attraction between the vehicle component and the vehicle structure.
2. The vehicle system of claim 1 , wherein the vehicle component comprises a vehicle display unit.
3. The vehicle system of claim 2 , wherein the vehicle structure comprises a vehicle instrument panel.
4. The vehicle system of claim 1 , wherein the controller is configured to generate a command to decrease the amount of electromagnetic attraction between the vehicle structure and the vehicle component in response to the received vehicle threat signal.
5. The vehicle system of claim 1 , wherein the vehicle threat signal received by the controller is transmitted to the controller from the sensor based on a sensed vehicle impact event.
6. A method of operating a vehicle, comprising the steps of:
sensing at least one of an expected vehicle impact event and a vehicle impact event;
varying an amount of electromagnetic attraction coupling a vehicle component to a vehicle structure based on the sensed at least one of the expected vehicle impact event and the vehicle impact event; and
yieldingly maintaining the vehicle component in a use position relative to the vehicle structure via an attachment feature, irrespective of the amount of electromagnetic attraction coupling the vehicle component to the vehicle structure.
7. The method of claim 6 , wherein the amount of electromagnetic attraction coupling the vehicle component to the vehicle structure decreases based on the sensed at least one of the expected vehicle impact event and the vehicle impact event.
8. The method of claim 7 , wherein the amount of electromagnetic attraction coupling the vehicle component to the vehicle structure decreases such that electromagnetic attraction between the vehicle component and the vehicle structure is substantially eliminated based on the sensed at least one of the expected vehicle impact event and the vehicle impact event.
9. The method of claim 6 , wherein the vehicle component comprises a vehicle display unit.
10. The method of claim 9 , wherein the vehicle structure comprises a vehicle instrument panel.
11. A vehicle system, comprising:
a vehicle structure;
a vehicle component coupled to the vehicle structure via electromagnetic attraction;
a controller configured to vary an amount of electromagnetic attraction; and
an attachment feature that additionally couples the vehicle structure and the vehicle component, wherein the attachment feature is configured to yieldingly maintain the vehicle component in a use position relative to the vehicle structure irrespective of the amount of the electromagnetic attraction coupling the vehicle component to the vehicle structure.
