Abstract
Official abstract text for this publication.
Provided is an electric power steering system that prevents the oscillation of the steering wheel at each steering stroke end. If the steering stroke end flag Fse is 1 or if the determination result is Yes in step S 8 , the EPS-ECU ( 21 ) determines if the right steering flag (Fdrc) is 1 in step S 10 . If the determination result is Yes, it is then determined if the steering torque difference base value (Dtsb) is positive in step S 11 . If the determination result of step S 11 is Yes, the EPS-ECU ( 21 ) uses the steering torque difference base value (Dtsb) as the steering torque difference (Dts) in step S 12 . If the determination result is No, the steering torque difference (Dts) is given by a value 0 in step S 13 , and the control process is concluded.
First claim
Opening claim text (preview).
The invention claimed is: 1. An electric power steering system, comprising: an electric steering assist motor that applies an assist force to a steering mechanism; a steering angle detector that detects a steering angle of a steering wheel; a target steering torque setting unit that sets a target steering torque of the steering wheel according to a detection result of the steering angle detecting means detector; an actual steering torque detector that detects an actual steer…
