Abstract

Methods, systems, and vehicles are provided for controlling an angle of a wheel assembly for vehicle events. In accordance with one embodiment, the vehicle includes a wheel assembly, a structural member, a detection unit, an actuator, and a processor. The detection unit is configured to detect an event for a vehicle that has a wheel assembly. The processor is coupled to the detection unit, and is configured to utilize an actuator to adjust an angle of the wheel assembly in a manner that guides energy absorption or transference from the event toward the structural member.

First claim

We claim:

1. A method comprising:
detecting, using a detection unit comprising one or more sensors, an event for a vehicle that has a wheel assembly, wherein the event comprises an imminent contact event in which the vehicle impacts another vehicle or object; and
adjusting, via instructions provided from a processor, an angle of the wheel assembly in a manner that guides energy absorption or transference from the impact of the vehicle with the other vehicle or object.

2. The method of claim 1 , further comprising:
obtaining one or more parameters pertaining to a state of the vehicle; and
determining an optimal angle for the wheel assembly adjustment based on the event and the one or more parameters.

3. The method of claim 1 , wherein:
the step of detecting the event comprises detecting an imminent contact event in which the vehicle is likely to impact another vehicle; and
the step of adjusting the angle comprises adjusting the angle via one or more actuators that are coupled to the processor and configured to implement instructions from the processor to adjust the angle after an imminent contact event is determined in which the vehicle is likely to impact another vehicle, such that the adjustment of the angle of the wheel assembly is performed in a manner that guides energy absorption or transference from the impact of the vehicle with the other vehicle.

4. The method of claim 1 , wherein:
the step of adjusting the angle comprises, adjusting, via instructions provided from the processor, the angle of the wheel assembly in a manner that guides energy absorption from the event toward a structural member of the vehicle.

5. The method of claim 4 , wherein:
the step of adjusting the angle comprises, adjusting, via instructions provided from the processor, the angle of the wheel assembly in a manner that aligns the wheel assembly with the structural member.

6. The method of claim 5 , wherein:
the structural rail comprises a structural rail for the vehicle; and
the step of adjusting the angle comprises, adjusting, via instructions provided from the processor, the angle of the wheel assembly in a manner that aligns a portion of the wheel assembly with the structural rail.

7. The method of claim 1 , wherein:
the step of detecting the event comprises detecting the event based on receiving a customer override or input; and
the step of adjusting the angle comprises adjusting the angle after the customer override or input is received.

8. A system comprising:
a detection unit comprising one or more sensors configured to detect an event for a vehicle that has a wheel assembly, wherein the event comprises an imminent contact event in which the vehicle impacts another vehicle or object; and
a processor coupled to the detection unit and configured to adjust an angle of the wheel assembly in a manner that guides energy absorption or transference from the impact of the vehicle with the other vehicle or object.

9. The system of claim 8 , wherein:
the detection unit is configured to obtain one or more parameters pertaining to a state of the vehicle; and
the processor is configured to determine an optimal angle for the wheel assembly adjustment based on the event and the one or more parameters.

10. The system of claim 8 , wherein:
the detection unit is configured to determine an imminent contact event in which the vehicle is likely to impact another vehicle; and
the processor is configured to adjust the angle of the wheel assembly in a manner that guides energy absorption or transference from the impact of the vehicle with the other vehicle.

11. The system of claim 10 , further comprising:
one or more actuators that are coupled to the processor, the one or more actuators configured to adjust the angle by implementing instructions provided by the processor after an imminent contact event is detected.

12. The system of claim 8 , wherein:
the processor is configured to adjust the angle of the wheel assembly in a manner that guides energy absorption from the impact toward a structural member of the vehicle.

13. The system of claim 12 , wherein:
the processor is configured to adjust the angle of the wheel assembly in a manner that aligns the wheel assembly with the structural member.

14. The system of claim 13 , wherein:
the structural rail comprises a structural rail for the vehicle; and
the processor is configured to adjust the angle of the wheel assembly in a manner that aligns a portion of the wheel assembly with the structural rail.

15. A vehicle comprising:
a wheel assembly;
a structural member;
a detection unit comprising one or more sensors configured to detect an event for a vehicle that has a wheel assembly, wherein the event comprises an imminent contact event in which the vehicle impacts another vehicle or object; and
a processor coupled to the detection unit and configured to adjust an angle of the wheel assembly in a manner that guides energy absorption or transference from the impact of the vehicle with the other vehicle or object toward the structural member.

16. The vehicle of claim 15 , wherein:
the detection unit is configured to obtain one or more parameters pertaining to a state of the vehicle; and
the processor is configured to determine an optimal angle for the wheel assembly adjustment based on the event and the one or more parameters.

17. The vehicle of claim 15 , wherein:
the detection unit is configured to detect an imminent contact event in which the vehicle is likely to impact another vehicle; and
the processor is configured to adjust the angle of the wheel assembly in a manner that guides energy absorption or transference from the impact of the vehicle with the other vehicle.

18. The vehicle of claim 15 , wherein:
the processor is configured to adjust the angle of the wheel assembly in a manner that aligns the wheel assembly with the structural member.

19. The vehicle of claim 18 , wherein:
the structural rail comprises a structural rail for the vehicle; and
the processor is configured to adjust the angle of the wheel assembly in a manner that aligns a portion of the wheel assembly with the structural rail.

20. The vehicle of claim 15 , further comprising:
one or more actuators coupled between the processor and the wheel assembly, the one or more actuators configured to implement instructions from the processor to adjust the angle of the wheel assembly.
