The touch screen controller can recognize the control command inputted by the user by comparing the touch coordinates of the user detected through the touch panel with the coordinates of the control command displayed through the display. When an error occurs in the software of the terminal 500, the display unit 300 may display a message to notify the driver of the error. If an updated version with an improved software error is downloaded from the server 600, And can display a message informing of improvements and the like by the updated version. The display unit 300 may display a message informing the occurrence of an error and the download of an updated version in which the error is corrected so that the driver may recognize the necessity of installing the updated version.

When an error occurs in the software of the terminal 500, the processor 510 transmits error information including the name, error code, software version, and the like of the terminal 500 in which the error occurred, through the communication unit 520 to the server 600). In addition, when an error occurs in the terminal 500, the processor 510 may display a message indicating the occurrence of the error on the display unit 300. If an updated version with an improved error is downloaded from the server 600, And a message informing the user of the update of the update version and the like can be displayed on the display unit 300.

In addition, when the updated version of the software is downloaded, the processor 510 displays the downloaded update version installation message on the display unit 300. The processor 510 may display the update message of the update version differently according to the type of the downloaded update version, and may apply the installation time differently.

First, the processor 510 calculates the installation time of the updated version based on the capacity of the updated version and the processing speed of the processor 510 when the updated version of the software is downloaded. The processor 510 may calculate the install time of the update version or may receive information on the estimated install time of the update version from the server 600. [

The processor 510 judges whether the downloaded update version is software related to the running safety of the vehicle, and installs the update version if the software is related to the running safety, for example, the software related to the eCall or the SOS function described above A message is displayed on the display unit 300, and an updated version is installed. That is, in the case of the software related to the running safety of the vehicle (hereinafter referred to as the first software), since it is necessary for the running safety to directly apply the updated version with the error, the updated version can be installed immediately without the consent of the driver. However, when installing the updated version of the first software, the stability index (Psa) is calculated in consideration of the accident risk when the vehicle is running, and the update version can be installed when the stability index is equal to or greater than the reference value. The reference value can be variably set according to the situation.

For example, the processor 510 may determine a parameter related to the running speed of the vehicle, a parameter related to the number of warnings, a parameter associated with the vehicle position, a parameter associated with the weather, The stability index can be calculated based on the parameter Pt or the like. The parameters underlying the stability index calculation are not limited to the above examples.

More specifically, the processor 510 calculates the stability index using the following Equation (1) to which the weights W1, W2, W3, W4, and W5 are applied to the above-described parameters, respectively.

&Quot; (1) "

Psa = W1 * Ps + W2 * Pw + W3 * Pp + W4 * Pw + W5 * Pt

In Equation (1), the sum of the weights is set to be 1. The processor 510 may calculate each parameter according to a predetermined rule.

For example, when calculating the parameter Ps related to the running speed, the processor determines Ps to be 1 when the vehicle is stationary, sets Ps to 0 when the vehicle is traveling at a speed higher than a predetermined speed, / h The Ps value can be calculated by decrementing by 0.1 every time it is increased.

When calculating the parameter Pw related to the number of warnings, the processor may set a warning function of the vehicle, for example, a lane departure warning system (LDWS), a blind spot detection (BSD) , TPMS (Tire Pressure Monitoring System), etc., Pw is set to 1. If the warning is not less than the predetermined number of times, Pw is set to 0, and when the warning number is accumulated once, the value decreased by 0.1 is set to Pw . The above-described warning function is one example, but the present invention is not limited thereto.

Also, when calculating the parameter Pp related to the vehicle position, the processor uses the positional information such as navigation to determine Pp to be 0 when the vehicle is traveling in an accident bunch area, an intersection, a tunnel or a highway, Pp is set to 1 if the vehicle is not traveling, and a value decreased by 0.1 in every time when the time required for reaching the position such as the accident bunch area, intersection, tunnel or highway is reduced by a predetermined time interval below the predetermined reference time is set as Pp Value. ≪ / RTI > The aforementioned accident-prone areas, intersections, tunnels or highways are examples of areas where accidents are likely to occur, but the present invention is not limited thereto.

When calculating the parameters Pw related to the weather, the processor does not predict the weather information acquired through the communication unit 520, such as snow, rain, etc., The value Pw is decreased by 0.2 when Pw is set to 1, weather information is predicted such as snow, rain, etc., or when the predetermined conditions such as the subzero temperature or the nighttime traveling are satisfied one by one. Can be bought. The above-described snow, rain, sub-zero temperature, nighttime driving and the like are merely examples, and the conditions underlying the calculation of Pw are not limited thereto.

Also, when calculating the parameter (Pt) related to the installation time, the processor sets Pt to 1 if the installation time of the update version is less than 1 minute, Pt value to 0.1 when the installation time increases by 1 minute The mountain can be. It is needless to say that the above-mentioned one minute is an exemplary one and may be set to a different value.

The processor 510 calculates each parameter by the above-described method, and applies the calculated parameter to the above-described equation (1) to calculate the stability index. The processor 510 determines that the risk of an accident is low even if the first software is installed immediately, and installs the first software immediately if the calculated stability reference value is larger than the calculated stability reference value. If the calculated stability index is smaller than the reference value, the processor 510 may install the update software without installing the first software immediately, install the software at the next startup, update the stability index in real time, and if the stability index becomes larger than the reference value have.

Meanwhile, when the downloaded update version is not the first software, the processor 510 transmits software related to the function that operates in real time (hereinafter referred to as second software), for example, software related to a route guide function through the navigation map In the case of the second software, the display unit 300 displays an update version installation message. FIG. 5 illustrates an update message displayed on the display unit 300 of the vehicle according to an embodiment of the present invention. The display unit 300 displays an installation message as shown in FIG. 5, the installation message displayed on the display unit 300 includes a first object 400 that receives an instruction to agree to install the update version, such as "YES" A second object 410 that receives a command that disagrees with the installation of the updated version, such as "No ", a third object 410 that receives an instruction to display the message again after a predetermined time, such as" 420) and a fourth object (430) that receives an instruction to always install the updated version immediately when the updated version is downloaded, such as "Always Yes". The objects may be displayed in text as described above, or may be displayed in the form of an icon characterizing a characteristic represented by each object, or may be displayed together with a text and an icon.

If the driver selects the first object 400 through the predetermined touch gesture and agrees to the installation of the updated version, the processor 510 determines the time required for the installation of the updated version and the time required for the vehicle to reach the destination In comparison, if the installation of the update version can be completed before reaching the destination, the installation of the update version is performed.

If the installation of the update version can not be completed before the vehicle reaches the destination, the processor 510 performs the installation at the next startup, or displays a message such as that shown in FIG. 5 again at the next startup, You can also install an updated version when you get a command, update the time it takes to reach your destination in real time, and install an updated version before you reach your destination. If the installation of the updated version can not be completed before the vehicle reaches the destination, the above-described procedures performed by the processor 510 may be provided so as to select the procedure desired by the driver in the settings related to the software update function.

On the other hand, when the driver selects the fourth object 430, the processor 510 always installs the downloaded update version, and actively updates the software through communication with the server 600 whenever an error occurs have. The procedure following the selection of the fourth object 430 may also be provided for the driver to modify in the settings associated with the software update function.

On the other hand, if the downloaded update version is not the first software and the second software described above, the processor 510 may display an update version installation message on the display unit 300 at the next start of the vehicle. If it is not the running safety of the vehicle or the software functioning in real time, there is no big problem in driving the vehicle even if the software is not updated immediately, so the installation message of the updated version is displayed again at the next startup. Of course, this can also be provided for the operator to modify in settings related to the software update function. For example, if the update version is not the first software or the second software, the driver may modify the update version so that the update version is automatically installed at the next startup, and the update version is automatically installed after a predetermined time elapses.

The processor 510 transmits the download result of the updated version to the server 600 through the communication unit 520. When the error is transmitted again from the vehicle, the processor 510 may transmit the update result to the server 600 because the server 600 may not transmit or transmit the next version according to the installation result of the update version. The above-described software update method can be equally applied to the update of the ECU 505 as well as the various terminals 500 of the vehicle.

6 and 7 are flowcharts illustrating a method of updating vehicle software according to an embodiment.

6, if the vehicle has an error in the software of the terminal 500 (700), the vehicle transmits error information including the name of the terminal 500, the error code, the software version, Lt; / RTI > When the server 600 receives the error information (710), the server 600 searches (720) if the error-corrected software exists in the database (720), and updates Version (730).

When the update version is transmitted from the server 600, the vehicle downloads the transmitted update version and installs the downloaded update version (740). The vehicle transmits the installation result of the updated version to the server 600 (750), and the server 600 receives the transmission result (760) and determines whether to transmit another update version upon receiving the error information in the future.

The step 740 of FIG. 6 will be described in more detail with reference to FIG.

As shown in FIG. 7, when the updated version is downloaded 800, the processor 510 calculates 810 the installation time of the updated version and determines 820 whether the downloaded updated version is the first software. If the updated version is the first software, the processor 510 calculates a stability index (830). If the calculated stability index is larger than the reference value (840), the processor 510 installs an update version (850).

When the updated version of the software is downloaded, the processor 510 calculates the installation time of the updated version based on the capacity of the updated version and the processing speed of the processor 510. [ The processor 510 may calculate the install time of the update version or may receive information on the estimated install time of the update version from the server 600. [

The processor 510 determines whether the downloaded update version is the first software related to the driving safety of the vehicle, displays a message on the display unit 300 to install the updated version if the software is the first software, do. That is, in the case of the first software, since it is necessary for the running safety to directly apply the updated version with the improved error, the updated version can be installed immediately without the consent of the driver. However, when installing the updated version of the first software, the stability index (Psa) is calculated in consideration of the accident risk when the vehicle is running, and the update version can be installed when the stability index is equal to or greater than the reference value. The description of how to calculate the stability index is redundant and is omitted.

If the update version is not the first software, the processor 510 determines (860) if the update version is not the first software, displays the update version install message (870) if the second software is the second software, 880), and if an update version can be installed (890) before the destination is reached, install the update version.

Meanwhile, if the downloaded update version is not the first software, the processor 510 determines whether the downloaded software is the second software related to the function that operates in real time, and if the software is the second software, 300). The display unit 300 displays an installation message as shown in FIG. 5, the installation message displayed on the display unit 300 includes a first object 400 that receives an instruction to agree to install the update version, such as "YES" A second object 410 that receives a command that disagrees with the installation of the updated version, such as "No ", a third object 410 that receives an instruction to display the message again after a predetermined time, such as" 420) and a fourth object (430) that receives an instruction to always install the updated version immediately when the updated version is downloaded, such as "Always Yes".

If the driver selects the first object 400 through the predetermined touch gesture and agrees to the installation of the updated version, the processor 510 determines the time required for the installation of the updated version and the time required for the vehicle to reach the destination In comparison, if the installation of the update version can be completed before reaching the destination, the installation of the update version is performed.

If the downloaded update version is not the second software, the processor 510 displays an install message of the updated version at the next start (900).

On the other hand, if the downloaded update version is not the first software and the second software described above, the processor 510 may display an update version installation message on the display unit 300 at the next start of the vehicle. If it is not the running safety of the vehicle or the software functioning in real time, there is no big problem in driving the vehicle even if the software is not updated immediately, so the installation message of the updated version is displayed again at the next startup.
