1. A vehicle management device that manages a state of a vehicle on which a driving system for providing acceleration, a braking system for providing deceleration, and a steering system for providing steering are mounted as a basic function system, the vehicle management device comprising:
an anomaly determination unit configured to determine whether the vehicle has a travelling anomaly that is estimated to be related to a characteristic change of the basic function system in a management target scene of travelling scenes of the vehicle in which a travelling direction changes when the vehicle travels in an autonomous driving mode; and
a designation output unit configured to designate and output a replacement request of a component that is requested to be replaced according to a determined travelling anomaly from among a plurality of components constituting the basic function system,
wherein
the anomaly determination unit determines a trajectory following anomaly, in which a difference between a target trajectory and an actual traveling position of the vehicle deviates from an allowable range, as the travelling anomaly, and
when the difference deviates from the allowable range, and the travelling anomaly is estimated to be related to an other factor other than the characteristic change, the designation output unit postpones designation and output of the replacement request of the component, and
wherein
the vehicle management device manages the state of the vehicle using the driving system, the braking system and the steering system to ensure target followability for controlling the vehicle in an autonomous driving mode to follow a target based on an actual travelling position of the vehicle.
