Abstract

Claims (112)

1. A method of managing a fleet of vehicles, the method comprising, by a processor of a fleet management system:

receiving, from each vehicle of a fleet of vehicles, a vehicle identification number (VIN) for the vehicle, along with one or more data elements that comprise one or more of the following:

trip information comprising vehicle operational parameters gathered during a first run of the vehicle that was performed on behalf of a first entity, and

second trip information comprising second vehicle operational parameters gathered during a second run of the vehicle that was performed on behalf of a second entity;

generating a data block that comprises the VIN and the one or more data elements; and

saving the data block to a shared digital ledger that includes VINs and data elements for a plurality of the vehicles in the fleet of vehicles;

receiving a request from the first entity for trip information, authenticating the first entity,

using an access control policy to grant the first entity access to the first vehicle operational parameters but not the second vehicle operational parameters, and

presenting the first vehicle operational parameters to the first entity.

2. The method of claim 1 wherein:

the one or more data elements further comprise a software identification code that identifies the installed version of the software component; and

the method further comprises, by a deployment service of the fleet management system:

querying the shared digital ledger to return the installed version,

accessing a data set of available software component updates, and

in response to the installed version being older than a corresponding available software component update that is in the data set, transferring the corresponding available software component to the vehicle for installation to replace the installed version.

3. The method of claim 1 further comprising:

receiving an updated VIN for one of the vehicles;

generating a new data block that comprises the updated VIN and the VIN that was previously saved to the shared digital ledger for that vehicle; and

saving the data block to the shared digital ledger.

4. The method of claim 1 wherein:

the second vehicle operational parameters comprise an identifier and trip information for a first passenger who requested a ride from the second entity; and

5. The method of claim 1 wherein:

the second vehicle operational parameters comprise a route taken by the vehicle during a delivery performed on behalf of the second entity; and

using the access control policy to grant the first entity access to the first vehicle operational parameters but not the second vehicle operational parameters comprises ensuring that the first entity does not have access to the route.

6. The method of claim 1 , wherein the shared digital ledger is a permissioned ledger in which:

the fleet management system is permitted to access and save data to the shared digital ledger, and

the first entity and the second entity are permitted to access, but not save data to, the digital ledger.

7. The method of claim 1 wherein:

the one or more data elements further comprise the hardware identification code;

the hardware identification code identifies a sensor of the vehicle;

the one or more data elements also comprise current calibration information for the sensor of the vehicle; and

the method further comprises, by a processor:

querying the shared digital ledger to return previous calibration information for the sensor of the vehicle, and

in response to the current calibration information deviating from the previous calibration information by at least a threshold, causing a calibration action to be performed on the sensor.

8. The method of claim 1 , wherein:

each vehicle gathers data that it periodically transfers to an external system; and

the one or more data elements comprise log information indicating a status of transfer of the gathered data to the external system.

9. A vehicle fleet management system comprising:

a processor; and

programming instructions that are configured to cause the processor to:

receive, from each vehicle of a fleet of vehicles, a vehicle identification number (VIN) for the vehicle, along with one or more data elements that comprise one or more of the following:

trip information comprising vehicle operational parameters gathered during a first run of the vehicle that was performed on behalf of a first entity, and

second trip information comprising second vehicle operational parameters gathered during a second run of the vehicle that was performed on behalf of a second entity;

generate a data block that comprises the VIN and the one or more data elements;

save the data block to a shared digital ledger that includes VINs and data elements for a plurality of the vehicles in the fleet of vehicles;

receive a request from the first entity for trip information,

authenticate the first entity,

use an access control policy to grant the first entity access to the first vehicle operational parameters but not the second vehicle operational parameters, and

present the first vehicle operational parameters to the first entity.

10. The system of claim 9 , further comprising additional programming instructions that are configured to cause a deployment service to:

query the shared digital ledger to return an installed version of the software component;

access a data set of available software component updates; and

in response to the installed version being older than a corresponding available software component update that is in the data set, transfer the corresponding available software component to the vehicle for installation to replace the installed version.

11. The system of claim 9 , further comprising additional programming instructions that are configured to cause the processor to:

receive an updated VIN for one of the vehicles;

generate a new data block that comprises the updated VIN and the VIN that was previously saved to the shared digital ledger for that vehicle; and

save the data block to the shared digital ledger.

12. The system of claim 9 , wherein:

the second vehicle operational parameters comprise an identifier and trip information for a first passenger who requested a ride from the second entity; and

the programming instructions to use the access control policy to grant the first entity access to the first vehicle operational parameters but not the second vehicle operational parameters comprise instructions to ensure that the first entity does not have access to the identifier and the trip information for the first passenger.

13. The system of claim 9 , wherein:

the second vehicle operational parameters comprise a route taken by the vehicle during a delivery performed on behalf of the second entity; and

the programming instructions to use the access control policy to grant the first entity access to the first vehicle operational parameters but not the second vehicle operational parameters comprise instructions to ensure that the first entity does not have access to the route.
