A method for checking system errors is provided to check a sensor error or a control error in a system that uses sensing value data and controls an actuator and to find a part where an error has occurred in the system. To this end, the method comprises the steps of: acquiring two sensing value data obtained by sensing of system input variable; acquiring two sensing value data obtained by sensing of a status value; and comparing the change pattern of the difference between two sensing values at the same time on the input variable and the change pattern of the difference between two sensing values at the same time on the status value and determining whether the system is out of order according to whether the status of increase or decrease of the two change patterns is the same in a designated time zone. The two sensing value data on the input variable and the status value are data of sensing values that are symmetrical with the axis of the direction of axis X as the center, wherein Axis X is the axis of time. |
