Abstract
Official abstract text for this publication.
A steering control system for a vehicle includes an electric motor, a torque sensor, an angular velocity sensor, and a control unit. The electric motor applies assist force to a turning operation of a steering wheel. The torque sensor detects a torque generated in a steering system including the steering wheel and varying with the turning operation. The angular velocity sensor detects an angular velocity generated in the steering system and varying with the turning operation. The control unit computes an assist control amount for the turning operation by using the torque and the angular velocity, and, when an abnormality occurs in a torque detection operation, increases a control amount computed by using the angular velocity among control amounts that constitute the assist control amount as compared to that when torque sensor operation is normal and executes drive control over the electric motor based on the assist control amount.
First claim
Opening claim text (preview).
The invention claimed is: 1. A steering control system for a vehicle, comprising: an electric motor configured to apply assist force to a turning operation of a steering wheel; a torque sensor configured to detect a torque that is generated in a steering system including the steering wheel and that varies with the turning operation of the steering wheel; an angular velocity sensor configured to detect an angular velocity that is generated in the steering system including the s…
