A method for confirming a patch executed by a computer, the method comprising: a) receiving, by the computer, first configuration information including a value for confirming authenticity and version identity of a control program from a control unit which executes a plurality of control programs for controlling equipment loaded onto an automobile, the control unit being loaded onto the automobile; b) selecting, by the computer, a target control program (B-TT77) which is to be corrected from among the plurality of control programs on the basis of the received first configuration information; c) selecting, by the computer, a patch to be applied to the target control program on the basis of the received first configuration information, and calculating, by the computer, second configuration information including a value for confirming the authenticity and the version identity of the target control program by which a normality of the target control program is guaranteed when a value is normal from among parameters of the target control program when applying the patch to the control unit; d) transmitting, by the computer, the patch to the control unit; e) receiving, by the computer, from the control unit third configuration information on a value for confirming the authenticity and the version identity of the target control program by which a normality of the target control program is guaranteed when a value is normal from among parameters of the target control program after applying the transmitted patch to the control unit; f) comparing, by the computer, the received third configuration information with the calculated second configuration information; and g) judging, by the computer, whether or not processing of applying the patch to the control unit has succeeded on the basis of a result of the comparison, wherein when the value for confirming the authenticity and the version identity of the control program is matched, the process of applying the patch is judged to have succeeded. a) receiving, by the computer, first configuration information including a value for confirming authenticity and version identity of a control program from a control unit which executes a plurality of control programs for controlling equipment loaded onto an automobile, the control unit being loaded onto the automobile; b) selecting, by the computer, a target control program (B-TT77) which is to be corrected from among the plurality of control programs on the basis of the received first configuration information; c) selecting, by the computer, a patch to be applied to the target control program on the basis of the received first configuration information, and calculating, by the computer, second configuration information including a value for confirming the authenticity and the version identity of the target control program by which a normality of the target control program is guaranteed when a value is normal from among parameters of the target control program when applying the patch to the control unit; d) transmitting, by the computer, the patch to the control unit; e) receiving, by the computer, from the control unit third configuration information on a value for confirming the authenticity and the version identity of the target control program by which a normality of the target control program is guaranteed when a value is normal from among parameters of the target control program after applying the transmitted patch to the control unit; f) comparing, by the computer, the received third configuration information with the calculated second configuration information; and g) judging, by the computer, whether or not processing of applying the patch to the control unit has succeeded on the basis of a result of the comparison, wherein when the value for confirming the authenticity and the version identity of the control program is matched, the process of applying the patch is judged to have succeeded.
