Title:
STEERING CONTROL DEVICE AND STEERING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2024/047788
Kind Code:
A1
Abstract:
A steering control device (10) executes operation amount calculation processing, estimation processing, correction processing, and operation processing. The operation amount calculation processing calculates an operation amount of control of using a steering torque as a control amount and using a target steering torque as a target value of the control amount. The estimation processing uses a nominal model and a filter to estimate a disturbance torque. The correction processing corrects the operation amount according to the disturbance torque estimated by the estimation processing. The operation processing operates the motor of a steering device so as to generate a torque corresponding to the operation amount corrected by the correction processing. The order of a polynomial of the denominator of the transfer function of the filter is higher than the order of a polynomial of the denominator of the transfer function of the nominal model.
