Embodiment Construction

[0069] A speed display device and a speed display method in an embodiment of the present disclosure will be described using the drawings. The speed display device of this embodiment is mounted on a vehicle and applied to a digital speedometer for graphic display.

[0070] figure 1 is a view showing the configuration of the digital speedometer 1 as the speed display device in the embodiment. The digital speedometer 1 has: a display panel 11 which is a part of an instrument panel of a vehicle; a graphic controller 13; a CPU (controller) 15; and various I / O interfaces 17, 18, and 19 connected to the CPU 15 .

[0071] The display panel 11 has: a TFT liquid crystal display (TFT-LCD) 11a that performs graphic display; and an instrument glass 11c that is provided on the TFT by sandwiching the inner portion 11b - Front of LCD11a (see figure 2 ). The display panel 11 is driven by an X driver 21 that applies a voltage in response to a horizontal synchronization signal and a Y dri...

Abstract

A speed displaying device is provided in a vehicle that travels to reach a set target speed, and displays a speedometer (30) which indicates a speed of the vehicle. The speed displaying device includes the speedmeter (30) having a scale (32) and a controller that controls to display a pointer (36) pointed position which indicates a position of current speed of the vehicle in the scale of the speedometer, a speed setting position (41) which indicates a position of the target speed in the scale of the speedometer, and a speed difference region (45) which indicates the size of the difference between the current speed and the target speed with an area on the speed meter. The speed difference region is displayed at a position near the scale of the speedometer.

Description

technical field [0001] The present invention relates to a speed display device and a speed display method for displaying a speedometer indicating the speed of a vehicle. Background technique [0002] Conventionally, there is a speed display device that displays a vehicle's speed and a set speed on a meter that graphically displays during cruise driving that automatically drives a car at a set speed. Image 6 is a view showing a display panel of a conventional speed display device. The display panel 111 has a TFT liquid crystal display (TFT-LCD) 111a, and a gauge glass 111c is provided in front of the TFT liquid crystal display 111a. A circular speedometer 130 is displayed on the screen of the display panel 111 . A pointer 136 indicating the speed of the vehicle is rotatably displayed on the speedometer 130 . [0003] An ODO / TRIP meter 138 representing distance traveled is displayed at the bottom of the speedometer 130 . At the lower corner of the screen of the display pan...
