Reducing surface rigidity of a vehicle
View Patent ↗Aspects of the disclosure relate altering the rigidity of a vehicle's surface. More particularly, the vehicle may contain tension members that are arranged so that a change in tension across one or more of the tension members will alter the rigidity of the vehicle's surface. The vehicle may identify and respond to a potential collision by altering the tension that is applied to one or more tension members, thereby altering the rigidity of the vehicle's surface.
1. A method for altering a vehicle's rigidity, the method comprising:
detecting an object in a vehicle's surroundings;
determining, by one or more processors, that the object and the vehicle will collide; and
altering, by the one or more processors, a tension in one or more tension members to alter a rigidity of a portion of the vehicle based on the determination that the object and the vehicle will collide.
2. The method of claim 1 , wherein the one or more tension members are cables.
3. The method of claim 1 , wherein altering the tension in the one or more tension members comprises reducing the tension by one of cutting, releasing, or loosening the one or more tension members.
4. The method of claim 1 , wherein the one or more tension members are arranged with respect to a surface of the vehicle so that a reduction of tension in the one or more tension members reduces rigidity of the surface.
5. The method of claim 4 , wherein the surface is at least one of a hood, bumper, or panel of the vehicle.
6. The method of claim 4 , wherein at least a portion of the surface is corrugated.
7. The method of claim 1 , wherein the one or more tension members are arranged with respect to a pillar of the vehicle so that reduction of tension in the one or more tension members reduces rigidity of the pillar.
8. The method of claim 7 , wherein the pillar comprises a plurality of sections, and wherein a sufficient tension within the one or more tension members prevents the plurality of sections from moving relative to one another.
9. The method of claim 1 , wherein detecting the object further comprises classifying the object, and wherein altering the tension in the one or more tension members is based, at least in part, on a classification of the object.
10. The method of claim 9 , wherein the classification of the object is one of a bicyclist, pedestrian, or animal.
11. A system for altering a rigidity of a vehicle, the system comprising:
one or more sensors to detect an object in a vehicle's surroundings;
one or more computing devices having one or more processors configured to:
determine that the object and the vehicle will collide; and
alter a tension in one or more tension members to alter a rigidity of a portion of the vehicle, based on the determination that the object and the vehicle will collide.
12. The system of claim 11 , wherein the one or more tension members are cables.
13. The system of claim 11 , wherein altering the tension in the one or more tension members comprises reducing the tension by one of cutting, releasing, or loosening the one or more tension members.
14. The system of claim 11 , wherein the one or more tension members are arranged with respect to a surface of the vehicle so that a reduction of tension in the one or more tension members reduces rigidity of the surface.
15. The system of claim 14 , wherein the surface is at least one of a hood, bumper, or panel of the vehicle.
16. The system of claim 14 , wherein at least a portion of the surface is corrugated.
17. The system of claim 11 , wherein the one or more tension members are arranged with respect to a pillar of the vehicle so that reduction of tension in the one or more tension members reduces rigidity of the pillar.
18. The system of claim 17 , wherein the pillar comprises a plurality of sections, and wherein a sufficient tension within the one or more tension members prevents the plurality of sections from moving relative to one another.
19. The system of claim 11 , wherein detecting the object further comprises classifying the object, and wherein altering the tension in the one or more tension members is based, at least in part, on a classification of the object.
20. The system of claim 11 , wherein the one or more processors are further configured to determine a likely impact between the vehicle and the object, and wherein altering the tension in the one or more tension members is based, at least in part, on the likely impact.
