Problems solved by technology

Therefore, drivers who are concerned about fuel consumption often use areas with low accelerator openings, which may result in driving at high accelerator openings for a long time
In addition, if the driver adjusts the accelerator operation amount by turning on and off the energy-saving lamp, the driver will frequently increase or decrease the accelerator operation amount near the threshold value of the switch lamp, which may increase the fuel consumption on the contrary.
[0006] In addition, although the display device described in Patent Document 2 calculates the instantaneous fuel consumption for comparison with the fuel consumption of the recommended driving mode, since the instantaneous fuel consumption is the past fuel consumption, it is impossible to instruct the accelerator to be pressed before the fuel consumption increases. pressure way
In addition, since the cause of the instantaneous increase in fuel consumption is not displayed, the driver cannot judge whether it is an operation to avoid the increase in fuel consumption or an operation not to avoid the increase in fuel consumption.
Therefore, it is difficult to prevent the increase in fuel consumption by urging appropriate driving operations before the increase in fuel consumption
In addition, as with the display device described in Patent Document 1, since the accelerator operation amount is not clear about the distance between the threshold for displaying "proper" and the threshold for displaying "excessive depression", there is a problem of not knowing how much the accelerator should be pressed in the future.

Embodiment 1

[0046] The accelerator opening degree display device 1 of the present embodiment displays information that guides the driver's accelerator operation to a fuel-saving region to maintain high efficiency of the engine and drive system. Therefore, instead of simply displaying the two values ​​of the accelerator opening degree with good fuel economy and the accelerator opening degree with poor fuel economy, the current accelerator opening degree is displayed relative to the target accelerator opening degree, so that the driver The operation amount can be adjusted so as not to exceed the target accelerator opening, so efficient running can be realized.

[0047] figure 1 A functional block diagram of the accelerator opening display device 1 is shown. The accelerator opening degree display device 1 includes: sensors for detecting driving state and operating state, an engine ECU (Electrical Control Unit: electronic control unit) 14, and an instrument ECU 15, and these parts are connec...

Embodiment 2

[0105] [Display for suppressing repeated fluctuations in accelerator opening]

[0106] The driver depresses the accelerator pedal 13 to increase the output of the engine, and this output becomes a driving force for acceleration, climbing, or the like. However, if the accelerator pedal is depressed for a very short time, its driving force is not transmitted to the road surface but is consumed by the torque converter etc. and becomes friction heat. That is, depressing the accelerator pedal for an extremely short time cannot convert fuel consumption into running, so it is preferable to prevent such an operation from being repeatedly performed. In this embodiment, an accelerator opening degree display device 1 that suppresses repeated fluctuations in the accelerator opening degree will be described. In the accelerator opening degree display device 1 of the present embodiment, the variation of the cumulative depression amount relative to the average depression amount of the accele...

Abstract

The present invention discloses a accelerator level display device 1 includes an accelerator level detection unit 12 configured to detect an accelerator level; a target accelerator level determining unit 14b configured to determine a target accelerator level for the accelerator level; and a display unit 15a, 20 configured to display a target accelerator level indicator corresponding to the target accelerator level and an accelerator level indicator corresponding to the detected accelerator level. The display unit is configured to display the target accelerator level indicator as a fixed value regardless of the target accelerator level determined by the target accelerator level determining unit.

Description

technical field [0001] The present invention relates to an accelerator opening display device for displaying a driver's accelerator opening, and more particularly, to an accelerator opening display device and an accelerator opening display method for displaying an accelerator opening together with a target opening. Background technique [0002] Most drivers pay attention to driving in consideration of fuel consumption, and generally recommend driving that avoids idling, stopping idling, and sudden acceleration. However, it is not limited to the operation of worsening (increasing) the fuel consumption which is easy to understand by feeling, but the fuel consumption is also greatly affected by the acceleration operation during driving. Therefore, it is proposed to assist in improving (reducing) the fuel consumption based on the displayed information. Display device (for example, refer to Patent Document 1, Patent Document 2). [0003] The display device described in Patent Do...
