Abstract
Official abstract text for this publication.
A motor-driven steering controller for controlling a steering wheel of a vehicle. The controller includes a steering torque controlling unit, a braking force estimating unit, a right and left braking force difference estimating unit and an assist steering torque providing unit. The steering torque controlling unit controls a steering torque on the steering wheel depending on a steering operation. The braking force estimating unit estimates braking forces to be imposed on wheels of the vehicle. The right and left braking force difference estimating unit estimates difference between the braking forces to be imposed on the right and left wheels each estimated by the braking forces estimating unit. The assist steering torque providing unit provides an assist steering torque for the steering torque controlling unit on the basis of the difference in braking force between right and left wheels estimated by the right and left braking force difference estimating unit.
First claim
Opening claim text (preview).
What is claimed is: 1. An electric power steering assist controlling apparatus for a vehicle, comprising: a steering torque controlling unit controlling an electric power assisted steering motor to control a steering torque on a steering wheel depending on an operator's steering operation to reduce an operator's power required to operate the steering wheel; a braking force estimating unit for estimating braking forces to be imposed on wheels of the vehicle; a right and left br…
