Abstract
Official abstract text for this publication.
A controller of an electric power steering system includes: a basic assist component computing unit ( 60 ) that computes a first assist component (Ta 1 *) based on a steering torque (Th); a steered angle command value computing unit ( 61 ) that computes a steered angle command value (θt*) based on the sum of the steering torque (Th) and the first assist component (Ta 1 *); and a steered angle feedback controller ( 62 ) that computes a second assist component (Ta 2 *) through feedback control on an actual steered angle (θt). The controller further includes: a correction component computing unit ( 65 ) that computes a correction component (Tc*) based on a steering angle (θs); and an assist command value computing unit ( 50 ) that computes an assist command value (Ta*) by subtracting the correction component (Tc*) from the sum of the first assist component (Ta 1 *) and the second assist component (Ta 2 *).
First claim
Opening claim text (preview).
What is claimed is: 1. An electric power steering system comprising: an assist mechanism that applies assist force generated by a motor to a steering mechanism of a vehicle; and a controller that controls driving of the motor based on an assist command value that is a target value of a torque output from the motor, the controller including a basic assist component computing unit that computes a first assist component that is a basic component of the assist command value, base…
