Abstract

One variation may include a system including a mobile host having a vehicle compartment defined therein and a receiving platform in the vehicle compartment having a plurality of guide features for guiding vehicles into the vehicle compartment of the mobile host, and a loading station including a loading platform having a plurality of vehicle guide features for guiding vehicles over the loading platform and onto the receiving platform. One variation may include a method comprising loading a vehicle into a mobile host having a vehicle compartment defined therein, wherein the mobile host includes a receiving platform having a plurality of raised guide features, and wherein the loading comprises guiding the vehicle onto the receiving platform using the plurality of raised guide features.

Claims

1. A system comprising:

a mobile host having a vehicle compartment defined therein and a receiving platform in the vehicle compartment having a plurality of guide features for guiding vehicles into the vehicle compartment of the mobile host, and a loading station including a loading platform having a plurality of vehicle guide features for guiding vehicles over the loading platform and onto the receiving platform wherein the receiving platform includes at least one rotatable cam having features for locking to the vehicle.

2. A system as set forth in claim 1 wherein the plurality of guide features of the receiving platform and the plurality of guide features of the loading platform each comprise guiding tiles.

3. A system as set forth in claim 2 further comprising a plurality of vehicles each including a guide tile receptor constructed and arranged to receive the guide tiles.

4. A system as set forth in claim 1 further comprising a plurality of vehicles each having electronic communication device, and further comprising a first electronic communication system constructed and arranged to send guiding signals to the vehicles to autonomously guide the vehicles over the loading platform and into the mobile host.

5. A system as set forth in claim 4 wherein the mobile host includes second electronic communication system for communicating with the first electronic communication system and sending information regarding which areas of the vehicle compartment of the mobile host do not have a vehicle therein.

6. A system as set forth in claim 2 wherein the plurality of guide tiles are spaced apart to accommodate vehicles having varying wheel bases, overall widths, track dimensions, or wheel positions.

7. A system as set forth in claim 1 wherein the receiving platform includes a locking feature for locking a vehicle to the receiving platform.

8. The system is set forth in claim 1 wherein the receiving platform includes a mechanism for locking a vehicle to the receiving platform and for charging the vehicle.

9. A system as set forth in claim 8 wherein the receiving platform includes a plurality of guide tiles and wherein the mechanism for locking includes electrical contacts on the guide tiles.

10. A system as set forth in claim 8 wherein the receiving platform includes a pair of rotatable cams having features for locking to the vehicle and wherein the pair of rotatable cams have opposite charged electrical contacts.

11. A system as set forth in claim 10 further comprising a vehicle having a lock beam attached to a chassis of the vehicle, the lock beam having a first outwardly extending finger and having an opposite second outwardly extending finger, and wherein the rotatable cams comprises a first cam having a first pawl and a first recess constructed and arranged so that when the first cam is in a first position the first pawl is positioned over the first finger and so that the first finger is received in the first recess, and wherein the rotatable cams comprises a second cam having a second pawl and a second recess constructed and arranged so that when the second cam is in a first position the second pawl is positioned over the second finger and so that the second finger is received in the second recess.

12. A system as set forth in claim 11 wherein the receiving platform includes a first earn recess and a second cam recess and wherein the first cam and the second cam are constructed and arranged to rotate from the first position to a second position wherein the first pawl and the second pawl are received in the first cam recess and the second cam recess respectively.

13. A system the set forth in claim 3 wherein the receiving platform further includes a locking feature constructed and arranged to engage a mating locking feature on the vehicle.

14. A system as set forth in claim 13 wherein the mating locking feature on the vehicle comprises a locking feature on one of a chassis or the guide tile receptor.

15. A system as set forth in claim 1 further comprising a ramp pivotally connected to the mobile host to facilitate loading or unloading vehicles from mobile host.

16. A method comprising loading a vehicle into a mobile host having a vehicle compartment defined therein, wherein the mobile host includes a receiving platform having a plurality of raised guide features, and wherein the loading comprises guiding a vehicle onto the receiving platform using the plurality of raised guide features wherein the receiving platform includes at least one rotatable cam having features for locking to the vehicle.

17. A method as set forth in claim 16 wherein the receiving platform includes a first locking mechanism and wherein the vehicle includes a mating second locking mechanism, and locking the vehicle to the receiving platform using the first locking mechanism and the second locking mechanism.

18. A method as set forth in claim 16 wherein the vehicle includes a battery, and wherein the receiving platform includes a first locking and charging mechanism and wherein the vehicle includes a mating second locking and charging mechanism, and locking the vehicle to the receiving platform and charging the battery of the vehicle comprising moving the first locking and charging mechanism into engagement with the mating second locking and charging mechanism.

19. A method as set forth in claim 16 wherein the receiving platform includes at least one rotatable cam, the rotatable cam including at least one pawl, and wherein the vehicle includes pawl engagement feature, and rotating the at least one rotatable cam so that the at least one pawl engages the pawl engagement feature and so that the vehicle is locked to the receiving platform.

20. A method as set forth in claim 19 wherein the pawl engagement feature comprises an outwardly extending finger of a lock beam connected to the vehicle.
