Abstract
The embodiments may provide a motor control device including three current sensors provided in each phase of a three-phase inverter connected to a motor to detect a current of each phase, and a controller configured to generate a control signal for the motor based on a detected current, and, in case of a failure of at least one of the three current sensors, determine an estimated current based on the number of faulty current sensors with the failure and generate a control signal for the motor based on the estimated current. According to the embodiments, it is possible to implement a motor control device capable of protecting the safety of a driver through a fault tolerant control in case of a failure of a current sensor.
