1. A method of controlling an electromechanical brake system, the method comprising:
measuring a voltage of a motor;
measuring a current of the motor;
estimating a position of a component of the electromechanical brake system based on the voltage and the current;
estimating a force imposed by the component based on the voltage and the current; and
estimating a hydraulic pressure associated with a hydraulic brake system;
wherein in an apply operation, the estimated force of the component is corrected based on the hydraulic pressure; and
wherein in a release operation, the estimated position of the component is corrected based on the hydraulic pressure.
