Abstract
A suspension system of an embodiment includes: an estimation unit configured to use a trained model to estimate, from input information including a measured value of sprung acceleration, either or both of a stroke displacement amount indicating an amount of displacement of a shock absorber and a stroke velocity indicating a displacement velocity of the shock absorber; a calculation unit configured to calculate an estimated value of the sprung acceleration based on the estimation result from the estimation unit; and an abnormality determination unit configured to determine the presence or absence of an abnormality based on an error between the measured value of the sprung acceleration and the estimated value of the sprung acceleration.
Claims6
A suspension system including a shock absorber configured to generate a damping force for causing vibration of a spring interposed between a wheel and a vehicle body to converge, the suspension system being configured to adjust the damping force, the suspension system comprising:
- an estimation unit configured to use a trained model to estimate, from input information including a measured value of sprung acceleration, either or both of a stroke displacement amount indicating an amount of displacement of the shock absorber and a stroke velocity indicating a displacement velocity of the shock absorber;
- a calculation unit configured to calculate an estimated value of the sprung acceleration based on an estimation result from the estimation unit;
- and
- an abnormality determination unit configured to determine presence or absence of an abnormality based on an error between the measured value of the sprung acceleration and the estimated value of the sprung acceleration.
