Abstract
A steer-by-wire steering device may provide a steering reaction force to the driver when the electronic control system fails by securing mechanical reliability, suppress an increase in production costs while enhancing reliability, and secure the reliability of the steering angle sensing structure.
Claims19
A steer-by-wire steering device, comprising:
- a steering shaft;
- a first reaction force generator including at least one motor connected to the steering shaft, at least one electronic control unit (ECU) controlling the at least one motor to generate a first steering reaction force to the steering shaft, and at least one sensor for sensing a steering angle;
- and
- a second reaction force generator generating a second steering reaction force generated by rotation of the steering shaft to the steering shaft.
