Title:
WORK MACHINE CALIBRATION METHOD, WORK MACHINE CONTROLLER, AND WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2020/203314
Kind Code:
A1
Abstract:
A calibration method for a wheel loader (1) comprises steps (S12, S14), a step (S15), and a step (S16). In the steps (S12, S14), a detection voltage (V1', V2') is output for detecting the angle of a bell crank (18) in relation to a boom (14), at an indicated prescribed posture of the boom (14) and bucket posture. In the step (S15), the detection voltage (V1', V2') is converted to a bell crank angle (θ1', θ2') of the bell crank (18) in relation to the boom (14), on the basis of a bell crank angle conversion table (T1). In the step (S16), the conversion value is calibrated based on the relationship between the bell crank angle (θ1', θ2') and a bell crank angle (θ1, θ2) in the indicated bucket posture.
