Title:
劣化検出システム、ブレーキ制御装置、および劣化検出方法
Document Type and Number:
Japanese Patent JP6775710
Kind Code:
B2
Abstract:
A degradation detection system includes: a storage that stores measured values of command pressure and measured values of response pressure; and a simulator that calculates, using a physical model, the response pressure in accordance with the command pressure, thereby obtaining a waveform of the calculated response pressure corresponding to a waveform of the command pressure in a case in which the command pressure is changed. A waveform identifier identifies a waveform of the calculated response pressure that matches a waveform of the detected response pressure. A degradation identifier identifies a degraded component of a pressure regulating valve from a value of parameter acquired by the waveform identifier and a normal range defined for the parameter.
