Abstract
The present invention relates to steering apparatuses, and more specifically, to torque estimation apparatuses, and steering assist apparatuses and methods. The torque estimation apparatus can include a first estimator for estimating an eccentric mass of a steering wheel, and a second estimator for estimating an eccentric torque of the steering wheel.
Claims20
A torque estimation apparatus comprising:
- a controller corn rises a first estimator and a second estimator, wherein
- the first estimator calculating a standard deviation of driver torques, and estimating an eccentric mass of a steering wheel based on the standard deviation of the driver torques;
- the second estimator estimating an eccentric torque of the steering wheel based on the eccentric mass of the steering wheel using a steering angle detected by a steering angle sensor;
- and
- the controller sending a signal to a steering motor based on the eccentric torque of the steering wheel.
