Abstract
An object of the present invention is to grasp information regarding the state of a vehicle (for example, an automobile) that cannot be obtained from an OBD, and to monitor the state of the vehicle. An aspect of the present invention includes: a state estimation unit that estimates the state quantities of a monitoring-target vehicle based on sensor data obtained from sensors mounted on a mobile information terminal in the monitoring-target vehicle using a state estimation device that has learned the relationship between sensor data obtained from sensors mounted on a mobile information terminal in an arbitrary vehicle and state quantities of the arbitrary vehicle in advance; a state evaluation unit that executes evaluation regarding a state of the monitoring-target vehicle on the basis of the estimated state quantities of the monitoring-target vehicle; and an evaluation result output unit that outputs a result of the evaluation.
