Abstract

The mobility service base server includes: a vehicle-side unit including a first database that is generated for each vehicle based on vehicle data and stores a plurality of shadows representing state of the vehicle at a specific time; and a service-side unit including a second database that stores an index corresponding to each of the shadows stored in the first database and having information used for retrieving the shadows, and an interface unit configured to receive an access request from outside. The vehicle-side unit includes a vehicle control unit transmitting a control instruction according to the access request to the in-vehicle device mounted on a target vehicle. The vehicle control unit determines necessary or unnecessary instruction for the target vehicle according to the state of the target vehicle stored in the first database.

First claim

What is claimed is:

1 . A mobility service base server comprising:
a vehicle-side unit including a first database storing a plurality of shadows each of which represents a state of a vehicle at a specific time, each of the plurality of shadows being generated for the vehicle based on vehicle data provided from an in-vehicle device mounted on the vehicle; and a service-side unit including a second database storing an index corresponding to each of the shadows accumulated in the first database and having information to be used for searching for the each shadow, and an interface unit configured to receive an access request from an outside, wherein the vehicle-side unit further includes a vehicle control unit configured to transmit a control instruction according to the access request to the in-vehicle device mounted on a target vehicle, which is the vehicle to be accessed, when the interface unit receives the access request to the vehicle, and the vehicle control unit is configured to determine necessary or unnecessary instruction for the target vehicle according to the state of the target vehicle stored in the first database when the access request is received.

2 . The mobility service base server according to claim 1 , wherein
the first database has startup status information indicating whether the target vehicle is in a first state in which control according to the control instruction is executable or the target vehicle is in a second state in which the control according to the control instruction is not executable, and the vehicle control unit further includes a preliminary control execution unit configured to execute a preliminary control to transition the target vehicle to the first state before transmitting the control instruction according to the access request when the startup status information is the second state.

3 . The mobility service base server according to claim 2 , wherein
the vehicle control unit is configured to transmit the control instruction after confirming that the vehicle has transitioned to the first state by referring to the startup status information after the preliminary control has been executed.

4 . The mobility service base server according to claim 1 , wherein
the first database includes a corresponding data that is the vehicle data having a value according to the state of the vehicle changing before and after executing control according to the control instruction, and the vehicle control unit is configured to cancel transmission of the control instruction to the target vehicle when the corresponding data indicates a value after execution of the control according to the control instruction, and the vehicle control unit further includes a notification unit is configured to return to the interface unit a completion notification indicating that the control according to the control instruction has been completed.

5 . A vehicle access control method by a mobility service base server including a first database that is generated for each vehicle based on vehicle data provided by an in-vehicle device mounted on the vehicle and stores a plurality of shadows representing state of the vehicle at a specific time, a second database that stores an index corresponding to each of the shadows stored in the first database and having information used for retrieving the shadows, and an interface unit configured to receive an access request from outside, the vehicle access control method comprising:
determining necessary or unnecessary instruction for a target vehicle according to state of the target vehicle stored in the first database when the access request is received before transmitting a control instruction according to the access request to the in-vehicle device mounted on a target vehicle, which is the vehicle to be accessed, when the interface unit receives the access request for the vehicle.

6 . A non-transitory computer readable storage medium storing a program that causes a computer configuring a mobility service base server together with a first database that is generated for each vehicle based on vehicle data provided by an in-vehicle device mounted on the vehicle and stores a plurality of shadows representing state of the vehicle at a specific time, a second database that stores an index corresponding to each of the shadows stored in the first database and having information used for retrieving the shadows, and an interface unit configured to receive an access request from outside, the program causing the computer to function as a vehicle control unit that is configured to determine necessary or unnecessary instruction for a target vehicle according to state of the target vehicle stored in the first database when the access request is received before transmitting a control instruction according to the access request to the in-vehicle device mounted on a target vehicle, which is the vehicle to be accessed, when the interface unit receives the access request for the vehicle.
