  After the reference information amount is calculated in S503, the display data adjustment unit 160 determines the information amount from the display data group corresponding to the display data type indicated in the display instruction information stored in the display data storage unit 130. The display data having the maximum information amount is selected from the display data below the reference information amount (S504), and the selected display data is provided to the data display unit 17 (S505).

  The data display unit 17 displays the display data selected by the display data adjustment unit 160 in this way on the display 30.

As described above, according to the fourth embodiment, the reference information amount is calculated according to the user's age information stored in the age information storage unit 12, the screen display time and the font size according to the display data type, and the reference information Display data selected based on the quantity is displayed on the display 30. The displayed display data has an amount of information that can be read by the user within the display time in the set font size. That is, since display data having an amount of information suitable for the font size of the display data to be displayed is displayed on the screen, the user can be prevented from failing to read the display data within the screen display time.

Embodiment 4 shows an example in which display data types are classified into a plurality of groups according to the degree of urgency determined according to driving conditions, and the font size of the display data is increased as the degree of urgency of the group increases. It was. However, the font information and the screen display time may be determined for each display data type, not for each group, and the reference information amount may be obtained using Expression 4 based on the font size and the screen display time.

  Further, as in the second embodiment, not only the screen display time but also the user's reaction time is taken into consideration, and a value obtained by adding the reaction time according to the user's age (X = screen display time + response time) is used. The reference information amount may be obtained.

Further, when the font size and information amount of the display data are determined in advance, the screen display time of the display data to be displayed is calculated using the following equation 5 as in Reference Example 1 above. The display data may be displayed for the calculated screen display time.

Subsequently, Reference Example 2 not included in the present invention will be described below with reference to the drawings.

In Reference Example 2 , the information amount of the display data type to be displayed is determined in advance, and the minimum font size that can be read within the screen display time when information is displayed with the information amount is determined according to the age of the user. The display data of the determined font size is displayed on the screen.

FIG. 20 is a diagram showing functional blocks of the screen display control apparatus 10 in Reference Example 2 , and the same reference numerals are given to the same parts as the functional blocks shown in FIG. The display data storage unit 132 stores a plurality of display data having different font sizes for each display data type. The display time / information amount storage unit 142 stores a screen display time and an information amount for each display data type. The display data adjustment unit 162 specifies the screen display time and the information amount corresponding to the display data type indicated in the display instruction information based on the information stored in the display time / information amount storage unit 142, and specifies the specified display. Based on the time and the amount of information and the age information of the user, the font size of the display data to be displayed is determined, and the display data of the font size is selected.

  Here, the display data selection method in the display data adjustment unit 162 will be further described with reference to the flowchart shown in FIG.

Display data adjustment unit 16 2, the display instruction accepting section 15 receives the display instruction information via a (S601), the display time and the amount of information to the screen display time and the amount of information corresponding to the display data type indicated in the display instruction information It identifies based on the information memorize | stored in the memory | storage part 142 (S602). Subsequently, based on the user age information stored in the age information storage unit 12 and the screen display time and information amount specified in S602, the display data adjustment unit 162 uses the font size shown in Equation 6 below. Is determined (S603).

In Expression 6, values are already given for the information amount, the screen display time, the age, and the coefficients K _{1 to} K ₄ , and the variables are only the coefficients S _{1 to} S ₅ . Then, as described in the fourth embodiment, the coefficients S _{1 to} S ₅ are uniquely obtained by the function of the font size as shown in FIGS. 19A to 19E. Therefore, the display data adjustment unit 162 obtains the smallest font size among the font sizes satisfying Equation 6 while sequentially changing the font size, and determines the font size as the smallest font size that can be read within the display time.

  Next, the display data adjustment unit 162 selects display data having the font size determined in S602 from the display data group corresponding to the display data type indicated in the display instruction information stored in the display data storage unit 130. Then, the selected display data is provided to the data display unit 17 (S605).

According to Reference Example 2 , the font size of the display data displayed on the screen is appropriately changed according to the age of the user, the amount of display data information, and the screen display time. Therefore, since display data having a suitable font size is displayed on the display device according to the user's age, the amount of display data information, and the screen display time, it is possible to prevent the user from failing to read the display data. .

  In the above example, the display data storage unit 132 stores a plurality of display data having different font sizes for each display data type, and the display data adjustment unit 162 selects display data having the determined font size. Explained. However, for example, the display data storage unit 132 stores display data for each display data type, and the data display unit 17 sets the font size so that the display data adjustment unit 162 displays the screen with the font size determined. May be adjusted.
