         [0032]    The battery  140  is charged by power supplied from the outside to store high-voltage electric energy therein and supply operation power to the vehicle. The battery  140  is formed of at least one high-voltage battery cell. 
         [0033]    The BMS  130  checks a remaining capacity of the battery  140  to decide whether the battery  140  needs to be charged, and performs management depending on the supply of a charging current of stored in the battery to the respective components of the vehicle. The BMS  130  includes a battery controller unit (BCU)  131  controlling the battery. 
         [0034]    Here, the BMS  130  uniformly maintains a voltage difference between cells in the battery at the time of charging and using the battery to control the battery so as not to be over-charged or over-discharged, thereby increasing a lifespan of the battery. 
         [0035]    In addition, the BMS  130  may allow the vehicle to be driven for a long period of time by managing the use of a current, and includes a protection circuit for a supplied current. 
         [0036]    The interface unit  160  includes manipulation means for driving such as a steering wheel, an accelerator, and a brake. In addition, the interface unit  160  includes a plurality of switches, buttons, and the like, for operating a turn signal lamp, a tail lamp, a head lamp, a brush, and the like. 
         [0037]    The input unit  170 , which is an input means for inputting predetermined data by a manipulation of a user (for example, a driver), and includes a button, a switch, and a rotary switch, and an input function of a touch pad also serves as the input unit. 
         [0038]    The display unit  180  includes a display displaying information, a speaker outputting music, effect sound, and warning sound, various states, and the like. In the case in which the display unit  180  is a touch screen, the touch screen serves as an input unit inputting data depending on a touch manipulation as well as the display unit displaying information. 
         [0039]    The sensor unit  150  senses and inputs a signal generated during driving of the vehicle or a predetermined operation, and inputs the signal to the VCU  110 . The sensor unit  150  includes a plurality of sensors disposed inside and outside the vehicle to input various sensing signals. Here, kinds of sensors may also be different from each other depending on positions at which the sensors are installed. 
         [0040]    The MCU  120  generates a control signal for driving at least one connected motor to control driving of the motor. In addition, the MCU  120  allows high-voltage power to be changed to be appropriate for characteristics of the motor, and allows the changed power to be supplied to the motor. 
         [0041]    The VCU  110  manages the battery  140  through the BMS  130 , performs a control by generating and applying a predetermined command so that a set operation is performed depending on inputs of the interface unit  160  and the sensor unit  150 , and controls input and output of data to allow an operation state of a home appliance to be displayed. 
         [0042]    The VCU  110  not only controls the vehicle depending on the data input through the input unit  170 , but also allows information corresponding to the input data to be output through the display unit  180 . 
         [0043]    Particularly, the VCU  110  allows information related to a specific item selected depending on an input of the driver through the input unit  170  to be updated in real time depending on the driving of the vehicle and allows the information updated depending on the driving of the vehicle to be displayed in real time, with respect to an information screen displayed through the display unit  180 . 
         [0044]      FIG. 2  is an illustrative view illustrating an example of a main screen on which vehicle information of a vehicle and information on the surrounding of the vehicle are displayed according to an exemplary embodiment of the present disclosure. 
         [0045]    Referring to  FIG. 2 , vehicle information and information on the surrounding of the vehicle are displayed on a main screen  209  of the display unit  180 . 
         [0046]    A basic menu  205  and my menu  204  related to the vehicle information are displayed on the main screen  209  of the display unit  180 . 
         [0047]    When a predetermined menu item is selected through the input unit  170 , the VCU  110  controls the display unit  180  to display the selected menu item as my menu  204  on the main screen  209 . 
         [0048]    Here, the respective menu items configuring the main screen  209  consist of a widget of a selected specific item, and the widget may be basically mounted or be newly downloaded or updated through connection of a terminal, connection of the Internet, or the like. In addition, the widget may be additionally installed by providing a separate detachable memory and updating data of the memory. 
         [0049]    Here, the widget is not an icon simply displaying what the selected specific item is, but displays update information of the corresponding selected specific item updated depending on the driving of the vehicle in real time. That is, since a driving state of the vehicle and information depending on the driving of the vehicle are displayed in real time without a separate manipulation of the driver that is to confirm the update information of the corresponding selected specific item, the driver driving the vehicle may confirm the corresponding information without a separate manipulation distracting the driving of the vehicle in order to confirm the corresponding information. Therefore, the driver may concentrate on the driving of the vehicle. As a result, stability of the driving of the vehicle is enhanced. 
         [0050]    The VCU  110  may add or delete widgets for the respective menu items depending on the input of the input unit  170 , and may install the widgets for the respective menu items by sensing new data or changed data of the memory. Here, the vehicle further includes a data unit (not illustrated) in which widget data and the vehicle information are stored. 
         [0051]    My menu  204  is a menu selected by the driver, and a display position or size of my menu  204  may also be set by the driver. Here, my menu  204  is displayed at a size larger than that of the basic menu  205 . 
         [0052]    In addition, my menu  204  is updated in real time as the information on the driving of the vehicle is changed depending on the driving state, updated information is displayed by a widget through the display unit, and my menu may be displayed as an icon, an image, or a moving image. 
         [0053]    For example, a drivable distance  201 , charging station information  202 , and energy information  203  may be displayed in my menu  204  by the driver. 
         [0054]    These three my menus may be displayed at the same size, respectively, as illustrated in  FIG. 2 , and the drivable distance, a distance up to a charging station, and the energy information may be continuously updated and displayed in real time as the vehicle is driven. 
         [0055]    A size of each my menu may be varied depending on the number of selected menus, and a display size of each my menu may also be adjusted, such that any one of my menus may be displayed at a larger size. 
         [0056]    For example, the drivable distance may be displayed at the largest size, and the charging station information and the energy information may be displayed at a size smaller than that of the drivable distance at the right of the drivable distance. 
         [0057]    In addition, the VCU  110  may extract a use history (for example, a use frequency, a display size, or the like) of my menu depending on the driving of the vehicle by the driver, and may automatically update my menu that is being displayed depending on the extracted use history of my menu. Therefore, the driver may readily configure specific items specialized in his/her vehicle use history through my menu or update the corresponding information. 
         [0058]    In addition, the VCU  110  may generate a driving pattern of the driver driving the vehicle depending on data transferred from the BMS  130 , the interface unit  160 , and the sensor unit  150 , update a specific item selected as my menu in real time depending on the generated driving pattern, and display the updated specific item through the display unit  180 . 
         [0059]    Items such as eco-driving, a menu, reservation charging, reservation air conditioning, setting, and the like, may be displayed in the basic menu  205 . 
         [0060]    Here, the basic menu  205  may be positioned at any one of a left side, a right side, an upper portion, and a lower portion of the screen depending on setting. 
         [0061]      FIG. 3  is a flow chart illustrating a method of setting a menu screen of a vehicle according to an exemplary embodiment of the present disclosure. 
         [0062]    Referring to  FIG. 3 , displayed my menu may be selected and set through a setting item of the main screen  209  (S 310 ). 
         [0063]    In the case in which a preset item is present in my menu, the preset my menu item and remaining menu items that are not selected may be displayed in a state in which they are distinguished from each other, and my menu item is set depending on the data input through the input unit  170 , that is, selection of the driver. 
         [0064]    Here, the preset item may be removed and a new item may be added, and display information or a display scheme for each item may be changed. 
         [0065]    After my menu is set, the VCU  110  checks an item set in my menu (S 320 ). Here, the VCU  110  confirms whether or not my menu items are changed and the display information or the display scheme for each item is changed. 
         [0066]    The VCU  110  collects information on each item and calculates data on the collected information in order to display my menu items on the main screen  209  of the display unit  180  (S 330 ). 
         [0067]    For example, in the case of the drivable distance, a distance at which the vehicle may be driven ahead may be calculated depending on at least one of a remaining capacity of battery or fuel, a current driving speed, and a driving pattern. 
         [0068]    The VCU  110  allows my menu to be displayed on a screen of the display unit  180 , for example, the main screen  209  on the basis of the calculated data (S 340 ). 
         [0069]    Here, the VCU  110  continuously confirms whether or not the data are changed with respect to each my menu item (S 350 ), maintains a current display (S 340 ) in the case in which the data are not changed, and again calculates the changed data and changes and displays my menu in real time (S 360 ) in the case in which the data are changed. 
         [0070]      FIG. 4  is a flow chart illustrating a method of displaying information of a vehicle according to an exemplary embodiment of the present disclosure. 
         [0071]    When an item for the drivable distance is added at the time of setting my menu (S 410 ), the VCU  110  requests data to the BMS  130  and the sensor unit  150 . 
         [0072]    The BMS  130  measures a state of the battery  140  and inputs information on the state of the battery  140  to the VCU ( 110 ), and the sensor unit  150  collects information on a speed of the vehicle and a driving state of the vehicle and applies the information on the speed of the vehicle and the driving state of the vehicle to the VCU  110  (S 420 ). 
         [0073]    The VCU  110  calculates the drivable distance of the vehicle on the basis of the received information on the state of the battery and the speed of the vehicle (S 430 ). Here, the VCU  110  may calculate the drivable distance using other data, for example, additional data such as a driving pattern of the vehicle, a frequency at which the driver steps on a brake, an acceleration frequency, and the like, in addition to the remaining capacity of the battery and the speed of the vehicle. 
         [0074]    The VCU  110  outputs the calculated drivable distance through the display unit  180  (S 440 ). The drivable distance is displayed on the main screen  209  of the display unit  180 , as illustrated in  FIG. 2  described above. 
         [0075]    In addition, the VCU  110  may allow the state of the battery to be displayed on the main screen  209  on the basis of the received information on the state of the battery (S 450 ). 
         [0076]    My menu displayed as described above is continuously varied and displayed as the vehicle is driven. 
         [0077]    Meanwhile, in the case in which a map is selected (S 460 ) in the state in which the drivable distance and the state of the battery are displayed on the main screen  209 , the VCU  110  changes a screen of the display unit  180  into a map screen, displays a position of the vehicle on the map screen, and displays the drivable distance on the map screen (S 470 ). 
         [0078]    Here, my menu items such as the state of the battery, and the like, may be displayed together with the drivable distance on the map screen. In addition, information on the surrounding of the vehicle is also displayed on the map screen. In some cases, road guidance information is also displayed. 
         [0079]      FIGS. 5 and 6  are illustrative views illustrating a screen on which vehicle information of a vehicle and information on the surrounding of the vehicle are displayed according to an exemplary embodiment of the present disclosure. 
         [0080]    In the case in which the map is selected on the main screen  209 , the map is displayed on the screen of the display unit  180 , as illustrated in  FIG. 5 . 
         [0081]    My menu item, for example, a drivable distance  211  is displayed on any one side of the screen. Here, a position on which the drivable distance is displayed is changed depending on setting. In some case, when the driver clicks and drags a position, the drivable distance  211  moves to and is displayed on the dragged position. 
         [0082]    In addition, a remaining capacity  212  of the battery may be displayed as an image on any one side of the map screen. 
         [0083]    The road guidance information as well as the map information is included in the map screen, such that information on a distance up to a destination and a local time are displayed together with each other on the map screen. 
         [0084]    In addition, the information on the surrounding of the vehicle, for example, information on a charging station or an oil station is displayed on the map screen, as illustrated in  FIG. 6 . 
         [0085]    In the case in which the charging station is selected in my menu, a position  221  of a charging station or an oil station closest to the vehicle in a driving direction is displayed, and a distance up to the charging station or the oil station may also be displayed. 
         [0086]    As a result, the display system according to an exemplary embodiment of the present disclosure does not simply arrange icons, but sets and displays the specific item selected by the driver as my menu. Therefore, the display system may provide information changed in real time on the main screen, such that the driver may directly confirm the information updated in real time. In addition, since information of my menu displayed depending on a vehicle driving pattern of the driver is also updated and displayed depending on the driving of the vehicle, it is easy to confirm the information without a separate manipulation while driving the vehicle. 
         [0087]    As described above, the display system according to the exemplary embodiment of the present disclosure may not only simply display the driving information of the vehicle, but may also display the specific item related to the driving of the vehicle selected from the user by the widget in real time.
