ABNORMALITY DETECTION DEVICE AND ABNORMALITY DETECTION PROGRAM: abstract simplified (18005897)

• This abstract for appeared for patent application number 18005897 Titled 'ABNORMALITY DETECTION DEVICE AND ABNORMALITY DETECTION PROGRAM'

Simplified Explanation

The abstract describes an abnormality detection device that can analyze vehicle signals to identify abnormalities. The device uses a time window process to divide the signals into smaller time intervals and extract the data within each interval. A learning process is then used to create learned information based on the time-series data within the time windows. The device can reconstruct the time-series data using the learned information and calculate the error between the original and reconstructed data. Based on this error and the learned information, the device can determine the degree of abnormality in the vehicle signal.

Original Abstract Submitted

An abnormality detection device includes: a time window process part configured to divide, by time windows, each of a plurality of vehicle signals each including a time-series data and to extract the data included in the time window; a learning part configured to create learned information by means of learning using the time-series data in the vehicle signal divided by the time windows; and an abnormality degree calculation part configured to reconstruct the time-series data in the vehicle signal divided by the time windows, based on the learned information, thereby calculate an error between before and after the reconstruction, and further calculate an abnormality degree of the vehicle signal based on the calculated error and the learned information.
