Abstract
Disclosed herein are an apparatus and method for controlling a motor-driven power steering system. The apparatus for controlling a motor-driven power steering system includes an input/output interface connected to a motor angle sensor, a steering angle sensor, and a position controller, and a processor connected to the input/output interface, wherein, when a failure occurs in the motor angle sensor, the processor calculates a sum value of a result value obtained by applying a first weight value to a motor angle of a driving motor output from the motor angle sensor and a result value obtained by applying a second weight value to a steering angle of a steering wheel output from the steering angle sensor and feed the sum value back to a position controller.

An apparatus for controlling a motor-driven power steering system, the apparatus comprising:
- an input/output interface communicatively connected to a motor angle sensor, a steering angle sensor, and a position controller, wherein the motor-driven power steering system includes the motor angle sensor, the steering angle sensor, and the position controller, and a driving motor;
- and
- a processor communicatively connected to the input/output interface and the position controller operatively connected to the driving motor,
- wherein, based on a failure occurring in the motor angle sensor, the processor determines a first sum value of a result value obtained by applying a first weight value to a motor angle of the driving motor output from the motor angle sensor and a result value obtained by applying a second weight value to a steering angle of a steering wheel output from the steering angle sensor communicatively connected to the processor and controls the driving motor of the motor-driven power steering system by feeding the first sum value back to the position controller.
A method of controlling a motor-driven power steering system, which is performed in a computing device including a processor, the method comprising:
- based on a failure occurring in a motor angle sensor communicatively connected to the processor, determining, by the processor, a first result value by applying a first weight value to a motor angle of a driving motor output from the motor angle sensor;
- determining, by the processor, a second result value by applying a second weight value to a steering angle of a steering wheel output from a steering angle sensor communicatively connected to the processor;
- and
- determining, by the processor, a first sum value of the first and second result values;
- and
- controlling, by the processor, the driving motor of the motor-driven power steering system by feeding the first sum value back to a position controller communicatively connected to the processor and operatively connected to the driving motor.
