Safety-enhanced storage system for autonomous vehicle compute units
In one embodiment, a storage system includes one or more platforms to stow compute units of an autonomous or semi-autonomous vehicle in a storage compartment of the vehicle. The platform is configured to support a compute unit of the vehicle to avoid a crumple zone of the vehicle. The crumple zone of the vehicle is designed to crumple when colliding with an object. The storage system also includes one or more shear fasteners configured to fasten the compute unit to the platform. The one or more shear fasteners are configured to break in a predetermined direction in response to a predetermined amount of lateral force. The breakage of the one or more shear fasteners decouples the compute unit from the platform in a controlled direction.

9. The compute unit storage system of claim 1 , wherein the platform is configured to support the compute unit of the vehicle to be below a height of a passenger seat of the vehicle.
10. The compute unit storage system of claim 1 , wherein the connector is configured to maintain the connection between the compute unit and the portion of the vehicle when a collision causes the crumple zone to crumple.
11. The compute unit storage system of claim 1 , wherein the connector is configured to maintain the connection between the compute unit and the portion of the vehicle when the one or more shear fasteners break in the predetermined direction in response to the predetermined amount of lateral force.
12. The compute unit storage system of claim 1 , wherein the one or more shear fasteners includes an adhesive, a hook-and-loop fastener, or a magnetic contact configured to decouple in response to the predetermined amount of lateral force.
13. The compute unit storage system of claim 1 , wherein the one or more shear fasteners includes a shear bolt configured to fracture in response to the predetermined amount of lateral force.
14. The compute unit storage system of claim 1 , wherein the compute unit is stowed within a rearward storage compartment of the vehicle.
15. The compute unit storage system of claim 1 , wherein the compute unit is stowed within a frontward storage compartment of the vehicle.
16. The compute unit storage system of claim 1 , wherein the compute unit is stowed within a sideward storage compartment of the vehicle.
