Title:
CALIBRATION DEVICE, SUSPENSION SYSTEM, SADDLE-TYPE VEHICLE, AND CALIBRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2021/260781
Kind Code:
A1
Abstract:
This calibration device 100: uses the inductance of a sensor 23r and the capacitance of a capacitor to calculate a first coefficient A1 representing a relationship between the output value of the sensor 23r and the gain of the sensor 23r when a suspension device 23T has a minimum expansion/contraction amount; obtains a first output value P0 by multiplying A1 by a shortest output value P1 specified by using the output value of the sensor 23r at the minimum expansion/contraction amount; uses a first expansion/contraction amount X1 of the suspension device 23T in a state where a wheel 4 is not grounded and the operation amount X0 of the suspension device 23T, P1 and P0 to calculate an ideal value P2 of the sensor 23r at the first expansion/contraction amount X1; calculates a second coefficient A2 by dividing the actual output value P3 of the sensor 23r at the first expansion/contraction amount X1 by P2; and calculates a calibration value P4 of the sensor 23r by using P3, X1, X0, P0, and A2.
