Abstract
Provided is a vehicle-mounted device that can be mounted in a vehicle, including: a measurement unit configured to measure a propagation delay time of data between the vehicle-mounted device and another vehicle-mounted device mounted in the vehicle; and a determination unit configured to perform anomaly determination on a transmission line of the data, based on the propagation delay time measured by the measurement unit.
Claims11
A vehicle-mounted device that can be mounted in a vehicle, comprising:
- a measurement unit configured to measure a propagation delay time of data between the vehicle-mounted device and another vehicle-mounted device mounted in the vehicle;
- and
- a determination unit configured to perform anomaly determination on a transmission line of the data, based on the propagation delay time measured by the measurement unit.
A management device comprising:
- an acquisition unit configured to acquire positional information regarding a vehicle of interest in which a propagation delay time of data between vehicle-mounted devices mounted in the vehicle of interest satisfies a predetermined condition;
- and
- a determination unit configured to perform anomaly determination on a transmission line of the data in the vehicle of interest, based on the positional information regarding the vehicle of interest acquired by the acquisition unit and other information.
An anomaly determination method for use by a vehicle-mounted device mounted in a vehicle, comprising:
- a step of measuring a propagation delay time of data between the vehicle-mounted device and another vehicle-mounted device mounted in the vehicle;
- and
- a step of performing anomaly determination on a transmission line of the data, based on the measured propagation delay time.
An anomaly determination method for use by a management device, comprising:
- a step of acquiring positional information regarding a vehicle of interest in which a propagation delay time of data between vehicle-mounted devices mounted in the vehicle of interest satisfies a predetermined condition;
- and
- a step of performing anomaly determination on a transmission line of the data in the vehicle of interest, based on the acquired positional information regarding the vehicle of interest and other information.
An anomaly determination program for use by a vehicle-mounted device mounted in a vehicle, for causing a computer to function as:
- a measurement unit configured to measure a propagation delay time of data between the vehicle-mounted device and another vehicle-mounted device mounted in the vehicle;
- and
- a determination unit configured to perform anomaly determination on a transmission line of the data, based on the propagation delay time measured by the measurement unit.
