By U3, the lateral acceleration G applied to the vehicle is calculated based on the steering angle θ detected by the steering angle sensor 1 and the speed V detected by the vehicle speed sensor 2. At this time, the direction of the lateral acceleration G is also derived. The derivation process of the lateral acceleration G by the CPU 3 corresponds to a derivation unit.
Reference numeral 4 is a RAM for temporarily storing data.

Further, the CPU 3 controls the display unit 5 composed of a liquid crystal display to display a character image of an animal such as a cat on the screen as shown in FIG. 2, for example. Then, the CPU 3 compares the derived lateral acceleration G with two predetermined threshold values G1 and G2 (> G1) stored in the built-in ROM or the like of the CPU 3, and the lateral acceleration G is the threshold value G1. When it does not exceed, as shown in FIG. 2, the character image is displayed in the display area A of the display unit 5 substantially in the center thereof without changing its form.

On the other hand, when the derived lateral acceleration G exceeds the threshold value G1, the form of the character image is changed and displayed on the display unit 5. Specifically, as shown in FIG. 3, the character image is displayed on the display unit 5 so as to move in the direction of the lateral acceleration G while slightly fluctuating.

Further, when the derived lateral acceleration G exceeds the threshold value G2, the form of the character image is further changed and displayed on the display unit 5. Specifically, as shown in FIG. The image is displayed so as to be pressed against the end portion of the display unit 5 in the direction of the lateral acceleration G. Such a character image display process by the CPU 3 corresponds to a display control unit.

By the way, in order to change the form of the character image, the image data of the forms shown in FIGS. 3 and 4 are stored in advance in a registration unit or the like, which will be described later. If G1 is exceeded, the image data in the form as shown in FIG. 3 is read from the registration unit by the CPU 3 and displayed on the display unit 5, and the lateral acceleration G is the threshold G.
If it exceeds 2, the image data of the form as shown in FIG.
The PU 3 may read it from the registration unit and display it on the display unit 5.

Further, as shown in FIG. 1, a registration unit 7 including a ROM in which a plurality of character images that can be displayed on the display unit 5 are registered in advance is provided.
When a desired character image is selected from a plurality of character images such as animals such as cats and persons registered in the registration unit 7, the CPU 3 displays the selected character image on the display unit 5. ing. The operation unit 8 includes, for example, a resistive film type touch panel on the surface of the display unit 5, and detects a touch of a key image for selecting a character image displayed on the display unit 5, thereby registering the unit 7.
It is only necessary to select a character image desired by the user from the respective character images registered in and display it in the display area. The function of the operation unit 8 corresponds to the selection unit in the present invention.

As shown in FIG. 1, the present apparatus is provided with a date / time information holding unit 10 including an electronic calendar, an electronic clock, etc. for holding date / time information and deriving the current date / time, and the CP.
U3 is configured to change and display the appearance of the character image so as to match the current time or season of the date and time information storage unit 10. As a specific example, a character image is put on cold clothes in winter and seawater pants are put on in summer to display a character image that the user is not tired of.

(Global positioning System) A position detection unit 13 is provided for detecting the current position (latitude, longitude) of a traveling vehicle by receiving radio waves from a satellite, and a predetermined switching operation of the operation unit 8 as a switching unit is performed. And the display unit 5 by the CPU 3.
The display unit 5 is controlled to switch and display the character image or the navigation map.

At this time, when the character image is displayed on the display unit 5, the CPU 3 changes the appearance form of the character image according to the current position (latitude, longitude) of the vehicle detected by the position detection unit 13. It is designed to be displayed. For example, when traveling in a cold region, it is conceivable to wear cold clothes on the character image or to wear clothing peculiar to the region in which the character is traveling, as in winter.

When the navigation map is displayed on the display unit 5, the CPU 3 controls the map data storage unit 12 to include the current position (latitude, longitude) of the vehicle detected by the position detection unit 13. Data is read,
A road map based on the read map data is displayed on the display unit 5. At this time, the current position of the vehicle is displayed in a superimposed manner on the displayed map by a predetermined mark.

Further, as shown in FIG. 1, a communication unit 15 including a mobile phone having a function of connecting to the Internet.
When the communication unit 15 is connected to the Internet, the CPU 3 controls the display unit 5 to display the information acquired via the Internet on the display unit 5.

Therefore, according to the above-described embodiment, when the derived lateral acceleration G exceeds the threshold values G1 and G2, the form of the character image displayed on the display unit 5 by the CPU 3 is changed. By observing the change in the form of the character image displayed on the display unit 5, the driver can know that a large lateral acceleration is applied to the vehicle, and thus the driver can be prompted to drive safely.

In the above-described embodiment, the case where the derived lateral acceleration G is compared with two threshold values has been described. However, the threshold value serving as a reference for comparison is one or three.
It may be higher.
