Title:
STEERING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP3963111
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To realize rapid turning of a steering wheel to a neutral position by a self-aligning torque.
SOLUTION: A control device 14 detects operation angles ST, STa with a time interval of T seconds previously determined and operates an operation speed VEL of the steering wheel 1 by dividing a value obtained by reducing the formerly detected operation angle STa from the lately detected operation angle ST by a time T. A steering angle WH of a wheel 5 is simultaneously detected with a detection of the operation angle ST and an assumed pinion angle PI is operated by multiplying a predetermined gear ratio R on the steering angle WH. A deviation DEV=SI-PI of this operated assumed pinion angle PI and the operation angle ST is determined. The operation speed VEL and the deviation DEV are multiplied and if the multiplied value is a negative value, it is determined that the wheel 5 is returning to the neutral position by the self-aligning torque to stop driving of a steering actuator 2.
