(9) As illustrated in FIG. 1, the cluster information output apparatus for a vehicle in accordance with the embodiment of the present invention may include a plurality of peripheral control devices 50_1 to 50_n, a storage unit 30, a control unit 20, and a speaker 40.

(10) In the embodiment of the present invention, a cluster 10 of the vehicle may display various pieces of cluster information in a digital manner through a front LCD panel. The cluster information may include various vehicle states such as speed, engine RPM, traveling distance, safety belt state, door open/close state, fuel state, tire pressure state, engine overheat state, ABS state, airbag state, parking brake operation state, oil amount, and oil pressure, battery charge state.

(11) At this time, essential information for safety may be defined and set for items which may have an influence on safe driving, among the vehicle states.

(12) For example, the essential information for safety may be defined as basic regulations including fuel state, tire pressure state, engine overheat state, safety belt state, and door open/close state.

(13) The peripheral control device 50 may indicate a driver convenience system or driver assistance system with a display 60, and include an HUD (Head UP Display), an AVN (Audio Video Navigation) device and the like. When a smart device is paired with the AVN system through near field communication, the peripheral control device 50 may include the smart device.

(14) The peripheral control device 50 may be connected to the control unit 20 through internal communication of the vehicle, and have a function of outputting an operation state according to an operation state request from the control unit 20, and displaying cluster information on the screen of the display 60 when the cluster information is outputted from the control unit 20.

(15) When displaying the cluster information on the screen of the display 60, the peripheral control device 50 may divide the screen of the display 60, and reduce and display the information of the peripheral control device 50 on a divided screen such that the cluster information can be displayed on another divided screen. Alternatively, the information of the peripheral control device 50 may be displayed so as to be scrolled or circulated, or selectively displayed.

(16) In the present embodiment, the screen may be divided to display information. However, the method for displaying the cluster information and the information of the peripheral control device 50 may be designed in various manners.

(17) At this time, the internal communication of the vehicle may include one or more of CAN (Controller Area Network), LIN (Local Interconnect Network), FlexRay, and MOST (Media Oriented Systems Transport).

(18) The storage unit 30 may store cluster information and priority information on the peripheral control devices 50. Furthermore, the storage unit 30 may store voice information for the cluster information.

(19) When an error occurs in an operation state sensed from the cluster 10, the control unit 20 may determine operation states for the peripheral control devices 50, and output cluster information to peripheral control devices 50 capable of outputting the cluster information.

(20) At this time, the operation state of the cluster may indicate an abnormal state of a driver for driving a backlight of the front LCD panel, and can be checked through a connection state of the front LCD panel. Furthermore, the operation state of the cluster can be checked through a response signal received from the cluster 10 after the control unit 20 outputs a control signal to the cluster 10.

(21) Furthermore, when the control unit 20 determines the operation states of the first to n-th peripheral control devices 50_1 to 50_n connected through the internal communication of the vehicle and determines the first and second peripheral control devices 50_1 and 50_2 as the peripheral control devices 50 capable of outputting cluster information, the control unit 20 may output the cluster information to the first peripheral control device 50_1 in case where the first peripheral control device 50_1 has a higher priority between the first and second peripheral control devices 50_1 and 50_2.

(22) On the other hand, the control unit 20 may output the cluster information to both of the first and second peripheral control devices 50_1 and 50_2 capable of outputting cluster information.

(23) For example, when it is assumed that the first peripheral control device 50_1 is an HUD, the first peripheral control device 50_1 may display speed information, convenience device operation information, and TBT (Turn By Turn) information through the first display 60_1 at normal times, as illustrated in (a) of FIG. 2. However, when cluster information is outputted, the TBT information screen may be divided to display the cluster information as illustrated in (b) of FIG. 2.

(24) Furthermore, when it is assumed that the second peripheral control device 50_2 is an AVN device, the second peripheral control device 50_2 may display AVN information through the second display 60_2 at normal times, as illustrated in (a) of FIG. 3. However, when cluster information is outputted, the AVN information screen may be divided to display the cluster information, as illustrated in (b) of FIG. 3.

(25) However, when there are no peripheral control devices 50 capable of outputting cluster information according to the determination result for the operation states of the first to n-th peripheral control devices 50_1 to 50_n connected through the internal communication of the vehicle, the control unit 20 may read voice information stored in the storage unit 30 for the cluster information, and output the voice information through the speaker 40 such that a driver can recognize the essential information for safety.

(26) In accordance with the embodiment of the present invention, when an error occurs on the front LCD panel of the cluster 10, the cluster information output apparatus may determine the states and priorities of the peripheral control devices 50 and output the essential information for safety through the displays 60 of the peripheral control devices 50. Then, the fail safe function of the cluster 10 may be performed to stably maintain the vehicle state, thereby contributing to safe driving.

(27) FIG. 4 is a flowchart for describing a control method of a cluster information output apparatus for a vehicle in accordance with an embodiment of the present invention.

(28) Referring to FIG. 4, the control method of the cluster information output apparatus for a vehicle in accordance with the embodiment of the present invention will be described as follows. First, the control unit 20 may sense the operation state of the cluster 10 at step S10.

(29) The operation state of the cluster 10 may indicate an abnormal state of the driver for driving the backlight of the front LCD panel, and can be checked through the connection state of the front LCD panel. Furthermore, the operation state of the cluster 10 may be sensed through a response signal received from the cluster 10 after outputting a control signal to the cluster 10.

(30) Then, the control unit 20 may determine whether an error occurred in the cluster 10, based on the sensed operation state of the cluster 10, at step S20.

(31) When it is determined at step S20 that no error occurred in the cluster 10, the control unit 20 may normally output cluster information to the cluster 10 such that the cluster information is displayed through the cluster 10, at step S50.

(32) However, when it is determined at step S20 that an error occurred in the cluster 10, the control unit 20 may search peripheral control devices 50 capable of outputting cluster information, at step S30.

(33) The peripheral control device 50 may indicate a driver convenience system or driver assistance system with a display 60, and include an HUD, an AVN device and the like. When a smart device is paired with the AVN device through near field communication, the peripheral control device 50 may include the smart device.

(34) At this time, the peripheral control device 50 may be connected to the control unit 20 through the internal communication of the vehicle, and have a function of outputting an operation state according to an operation state request from the control unit 20, and displaying cluster information on the screen of the display 60 when the cluster information is outputted from the control unit 20.

(35) When displaying the cluster information on the screen of the display 60, the peripheral control device 50 may divide the screen of the display 60, and reduce and display the information of the peripheral control device 50 on a divided screen such that the cluster information can be displayed on another divided screen. Alternatively, the information of the peripheral control device 50 may be displayed so as to be scrolled or circulated, or selectively displayed.

(36) In the present embodiment, the screen may be divided to display information. However, the method for displaying cluster information and information of the peripheral control device 50 may be designed in various manners.

(37) At this time, the internal communication of the vehicle may include one or more of CAN, LIN, FlexRay, and MOST.

(38) Thus, the control unit 20 may request operation states from the peripheral control devices 50 through the internal communication of the vehicle, and search peripheral control devices 50 capable of cluster information in which no errors occur.

(39) The cluster information may include various vehicle states such as speed, engine RPM, traveling distance, safety belt state, door open/close state, fuel state, tire pressure state, engine overheat state, ABS state, airbag state, parking brake operation state, oil amount, oil pressure, and battery charge state.

(40) Thus, the essential information for safety may be defined and set for items which may have an influence on safe driving, among the vehicle states.

(41) For example, the essential information for safety may be defined by basic regulations including fuel state, tire pressure state, engine overheat state, safety belt state, and door open/close state.

(42) The control unit 20 may determine whether there exist peripheral control devices 50 capable of cluster information, at step S40.

(43) When it is determined at step S40 that there are peripheral control devices 50 capable of outputting cluster information, the control unit 20 may output cluster information to one or more of the peripheral control devices 50 such that the cluster information can be displayed through the display 60 of the corresponding peripheral control device 50, at step S60.

(44) At this time, the control unit 20 may output the cluster information to a peripheral control device 50 having a high priority according to the priority information on the peripheral control devices.

(45) Furthermore, the control unit 20 may output the cluster information to all peripheral control devices 50 capable of outputting the cluster information.

(46) When the peripheral control devices 50 are searched at step S40, the control unit 20 may request an operation state from a peripheral control device 50 according to the priority, and output and display cluster information in case where the operation state is normal. That is, when an error occurred in a peripheral control device 50 according to the priority, the control unit 20 may determine the operation state of the peripheral control device 50 having the next priority, and output cluster information.

(47) When it is determined at step S40 that there are no peripheral control devices 50 capable of outputting cluster information, the control unit 20 may read voice information stored in the storage unit 30 for the cluster information, and output the voice information through the speaker 40 such that a driver can recognize the essential information for safety, at step S60.

(48) In accordance with the embodiment of the present invention, when an error occurs on the front LCD panel of the cluster 10, the cluster information output apparatus for a vehicle may determine the state and priory of a peripheral control device 50 and output the essential information for safety through the display 60 of the peripheral control device 50. Thus, the fail safe function of the cluster may be performed to stably maintain the vehicle state, thereby contributing to safe driving.

(49) Although embodiments of the invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as defined in the accompanying claims.
