an acquisition unit that acquires types of boarding information indicating that one of users boards or is on board the vehicle when one of the motions is detected; a memory that stores association information in which identification information of the users is associated with the types of boarding information corresponding to the users; a probability calculating unit configured to calculate a probability that each of the users boards or is on boarded the vehicle based on the types of boarding information and the association information; and an identification unit that identifies a user who boards or is on boarded the vehicle among the users based on the probability calculated by the probability calculating unit. ## Claims ### Claim 1 A user identification system comprising: a sensor configured to detect a plurality of prescribed motions as motions of a person when the person performs at least one of boarding and alighting from a vehicle; an acquisition unit configured to acquire a plurality of types of boarding information indicating that one of a plurality of users registered in the vehicle in advance boards or is on board the vehicle when one of the plurality of motions is detected; a memory configured to store association information in which identification information corresponding to the plurality of users is associated with the plurality of types of boarding information corresponding to the plurality of users; a probability calculating unit configured to calculate a probability that each of the plurality of users boards or is on board the vehicle based on the plurality of types of boarding information and the association information; and an identification unit configured to identify a user who boards or is on board the vehicle among the plurality of users based on the probability calculated by the probability calculating unit. ### Claim 2 (depends on 1) The user identification system according to claim 1, wherein the plurality of types of boarding information include a first type of boarding information which is acquired to correspond to one of a plurality of seats in the vehicle, and the identification unit identifies a seat of the user who boards or is on board the vehicle among the plurality of seats based on the first type of boarding information acquired by the acquisition unit. ### Claim 3 (depends on 1) The user identification system according to claim 1, further comprising a locking-unlocking unit configured to lock and unlock a door of the vehicle, wherein the plurality of users include a first user and a second user who has been set to be permitted to board the vehicle along with the first user in advance, and the locking-unlocking unit is configured to unlock a door of the vehicle when the first user is identified as a user who is on board the vehicle by the identification unit, the second user is identified as a user who boards the vehicle by the identification unit in a state in which all doors of the vehicle are locked, and a predetermined operation on the vehicle is performed from outside of the vehicle. ### Claim 4 (depends on 1) The user identification system according to claim 1, further comprising: a mutual boarding frequency counting unit configured to count a mutual boarding frequency of each pair of the plurality of users based on an identification result of the identification unit; and a locking-unlocking unit configured to lock and unlock a door of the vehicle, wherein the plurality of users include a first user and a second user, the mutual boarding frequency of the second user with the first user being equal to or greater than a predetermined frequency, and the locking-unlocking unit is configured to unlock the door of the vehicle when the first user is identified as a user who is on board the vehicle by the identification unit, the second user is identified as a user who boards the vehicle by the identification unit in a state in which all doors of the vehicle are locked, and a predetermined operation on the vehicle is performed from outside of the vehicle. ### Claim 5 (depends on 3) The user identification system according to claim 3, wherein the locking-unlocking unit is configured to unlock only the door which is opened by the second user. ### Claim 6 (depends on 1) The user identification system according to claim 1, further comprising a control unit configured to control an on-board device mounted in the vehicle based on a control condition set in advance to correspond to the user identified by the identification unit among the plurality of users. ### Claim 7 (depends on 1) The user identification system according to claim 1, wherein the user identification system is mounted in the vehicle. ### Claim 8 (depends on 1) The user identification system according to claim 1, wherein the memory, the probability calculating unit, and the identification unit are disposed remotely from the vehicle and configured to communicate with the vehicle.
