Title:
SHOCK ANALYSIS METHOD, FEATURE EXTRACTION METHOD, SHOCK ANALYSIS DEVICE, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/038744
Kind Code:
A1
Abstract:
The purpose of the present invention is to analyze information pertaining to a shock that occurred in a vehicle on the basis of an observation signal from a sensor mounted to the vehicle. An acquisition unit (11) acquires the observation signal from the sensor (S) mounted to a prescribed position on the vehicle. For each point in time, an analysis unit (12) uses the observation signal to analyze a shock type for a shock to the vehicle occurring in a different position from the mounted position of the sensor (S) on the vehicle. The shock type includes at least one among: the vehicle colliding with an obstacle; the vehicle going onto an uneven surface; a flying object colliding with the vehicle; the vehicle rubbing against an object other than the vehicle; and an object other than the vehicle rubbing against the vehicle. An output unit (13) outputs results obtained by analyzing the point in time at which the shock occurred and the shock type.
