Accordingly, the controller may control the operation of the driving unit to start again after stopping the driving unit for a predetermined time through steps S007 to S010.

At the same time, if the controller 10 determines that a warning message should be output through the steps S002 to S005, the alarm time timer module starts counting the alarm time timer before outputting the warning message (S011). In this case, the counted timer is made to be counted for any predetermined second time.

Thereafter, the control unit 10 generates and outputs a warning message through the warning message generation module (S012), continuously counts the timer through the warning time timer module, and determines whether the timer time exceeds the second time (S013). When the timer time is exceeded, the timer of the warning message timer module is stopped (S014), and the output of the warning message is stopped (S015).

Accordingly, the control unit may output the warning message for a predetermined time through steps S011 to S015, and then stop the output of the warning message.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it should be understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the present invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
