Abstract
A load estimation apparatus includes: an acceleration sensor attached to at least one of a bogie body supporting wheels or a vehicle body attached to the bogie body and configured to measure a first acceleration; and a control unit configured to estimate a load which is applied to the bogie body on the basis of load information which is acquired in advance and in which an acceleration and a load are correlated and the first acceleration.
Claims12
A load estimation apparatus comprising:
- an acceleration sensor attached to at least one of a bogie body supporting wheels or a vehicle body attached to the bogie body and configured to measure a first acceleration;
- and
- a control unit configured to estimate a load which is applied to the bogie body on the basis of load information which is acquired in advance and in which an acceleration and a load are correlated and the first acceleration,
- wherein a frequency of an acceleration which is determined on the basis of a change of the acceleration with time is further correlated in the load information, and
- wherein the control unit is configured to further estimate the load which is applied to the bogie body on the basis of the load information and the first acceleration
(canceled)
A load estimation method comprising:
- a step of measuring a first acceleration using an acceleration sensor attached to at least one of a bogie body supporting wheels or a vehicle body attached to the bogie body;
- and
- a step of estimating a load which is applied to the bogie body on the basis of load information which is acquired in advance and in which an acceleration and a load are correlated and the first acceleration,
- wherein a frequency of an acceleration which is determined on the basis of a change of the acceleration with time is further correlated in the load information, and
- wherein, in the step of estimating the load, further estimating the load which is applied to the bogie body on the basis of the load information and the first acceleration.
A program causing a computer of a load estimation apparatus to perform:
- a step of measuring a first acceleration using an acceleration sensor attached to at least one of a bogie body supporting wheels or a vehicle body attached to the bogie body;
- and
- a step of estimating a load which is applied to the bogie body on the basis of load information which is acquired in advance and in which an acceleration and a load are correlated and the first acceleration,
- wherein a frequency of an acceleration which is determined on the basis of a change of the acceleration with time is further correlated in the load information, and
- wherein, in the step of estimating the load, further estimating the load which is applied to the bogie body on the basis of the load information and the first acceleration.
