The display system shown in FIG. 1 includes a display device 1, a smartphone (small information acquisition terminal) 2, an external communication network (external storage medium) 3, and a short-range wireless communication 4.

  The display device 1 is a flat panel display such as an active matrix type liquid crystal display or an organic EL display driven by a TFT, and includes vehicle body information such as vehicle speed, engine speed, water temperature, oil temperature, exhaust temperature, and remaining fuel. An image (meter image) can be displayed and can be communicated with the smartphone 2 by the short-range wireless communication 4.

  The smartphone 2 is a high-function mobile phone that includes a touch panel that allows gesture operations and that can execute a plurality of applications (hereinafter also referred to as applications). The smartphone 2 is connected to an external communication network 3 and is connected to a short-range wireless communication 4. Can be used to communicate with the display device 1.

  The external communication network 3 is an external communication line such as 3G or Wi-Fi that can access joint information such as apps and road information and output the information to a smartphone.

  The short-range wireless communication 4 is a communication technology such as Bluetooth that enables mutual communication between the display device 1 and the smartphone 2 within a predetermined distance range.

  The display system configured as described above has a design customization function and a driving assist function. Details of each function will be described below.

  The design customization function uses an external communication network 3 to download and execute a customization application on the smartphone 2. The app for customization includes a list meter with many vehicle information items such as vehicle speed, engine speed, water temperature, oil temperature, exhaust temperature, and remaining fuel, a simple meter that displays only essential items such as vehicle speed and remaining fuel, the number of stops Ecometers centering on the display of vehicle information, which is an indicator of eco-driving such as instantaneous fuel consumption, sports meters that display vehicle information related to driving operations such as engine speed and shift-up indicators, etc. Various design templates such as reprinted in-vehicle meters composed of car meter designs can be saved on the smartphone 2, and the color, size, and selection of design template display items can be arbitrarily customized on the smartphone 2. Is. At this time, as shown in FIG. 2, enlargement / reduction of display items, selection, layout change, and the like can be performed by gesture operations using the touch panel. In the example illustrated in FIG. 2, a design template including an analog meter image indicating a fuel meter, an analog data image indicating a water temperature meter, an analog data image indicating a speedometer, and a digital data image indicating a speedometer as display items is displayed on the smartphone 2. The image is stored and displayed, and the user performs enlargement / reduction of each image, deletion of display, addition of a new image, and the like by a gesture operation using the touch panel. The smartphone 2 performs initial communication with the display device 1 after the vehicle is turned on, that is, after activation, and automatically transmits stored information to the display device 1 using the short-range wireless communication 4 to customize the display design. When the template is changed by a gesture operation after the ignition is turned on, the change data is transmitted from the smartphone 2 to the display device 1 using the short-range wireless communication 4 by a predetermined operation, and the display design is changed based on the change data. Let them customize. According to the design customization function, the expressive power of the display device 1 can be fully utilized by a simple method using the smartphone 2.

  In addition, as an example of the display design based on the design template, display items corresponding to the date and place of the schedule stored and managed by the schedule app in conjunction with the schedule app installed on the smartphone 2 may be displayed on the display device 1. Good. FIG. 3 shows an example of the display.
