Title:
ANOMALY DETECTION APPARATUS
Document Type and Number:
Japanese Patent JP2022160161
Kind Code:
A
Abstract:
To provide a technology for detecting an anomaly of a mounting state of a temperature sensor.SOLUTION: An anomaly detection apparatus 1 includes a temperature acquisition unit 81, a fluctuation range calculation unit 83, an anomaly detection unit 85, and an anomaly notification unit 87. The temperature acquisition unit 81 acquires brake temperature, which is a temperature of a brake device 5, based on a signal from a temperature sensor 7 mounted on the brake device 5 of a vehicle. The fluctuation range calculation unit 83 calculates a fluctuation range in a predetermined period of inclination of the brake temperature acquired by the temperature acquisition unit 81. The anomaly detection unit 85 determines whether the fluctuation range calculated by the fluctuation range calculation unit 83 exceeds a predetermined value or not, and determines, when a determination is made that the fluctuation range exceeds the predetermined value, that anomaly of a mounting state of the temperature sensor 7 has occurred. When the anomaly detection unit 85 determines the occurrence of anomaly, the anomaly notification unit 87 issues a notification of the occurrence of anomaly.SELECTED DRAWING: Figure 6
