Title:
CONTROL DEVICE, DRIVE DEVICE, DRIVE POWER STEERING DEVICE, AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/029331
Kind Code:
A1
Abstract:
This control device calculates a sign-extended steering torque by performing moving average processing that weights an oversampled signal obtained by oversampling processing; on the basis of the sign-extended steering torque signal, the control device calculates a base assist torque and acquires a base assist torque signal that decreases the base assist torque such that the higher the vehicle speed, the more the base assist torque is reduced; and the control device performs stabilization processing on the base assist torque signal to obtain an assist torque signal corresponding to the assist torque of the electric power steering device, and reduces the assist torque signal gain in a frequency band above a prescribed frequency.
