First Claim
Patent Images
1. A vehicle steering device comprising:
- a rotation operating member that is operated to rotate a steering shaft;
an absolute operation angle detecting means that detects an absolute operation angle of the rotation operating member;
an operation-side motor that supplies an operating reaction force to the rotation operating member;
a speed reduction mechanism interposed between a motor shaft of the operation-side motor and the steering shaft to reduce athe rotation speed of the motor shaft and to transmit athe reduced rotation to the steering shaft;
a motor rotation angle detecting means provided at the motor shaft of the operation-side motor to detect a rotation angle of the operation-side motor;
a steering-side motor that changes a steering angle via a transmission mechanism;
a steering angle detecting means that detects the steering angle; and
a control means that controls driving of the steering-side motor based on the steering angle and the absolute operation angle of the rotation operating member, and that controls driving of the operation-side motor based on the steering angle and the rotation angle of the operation-side motor.
