Description

  The present invention relates to an accelerator opening conversion device that is installed in an automobile or the like and outputs an accelerator opening signal that is amplified or attenuated.

  Conventionally, an accelerator opening that is interposed between an accelerator and a fuel control device (throttle control device) in a vehicle such as an automobile, attenuates the accelerator opening signal from the accelerator, and outputs the attenuated signal to the fuel control device side. There is a conversion device (see Patent Document 1).

  According to this accelerator opening conversion device, since the attenuated signal is input to the fuel control device side with respect to the actual accelerator depression amount by the driver, the fuel consumption can be reduced. This accelerator opening conversion device also discloses a technique for displaying an accelerator opening signal (after conversion) within a range of 0% to 100% to the driver by using a display device such as an LCD. .

  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 shows an overall configuration of a retrofit accelerator opening conversion device (hereinafter referred to as an opening conversion device) 1 according to the present embodiment. Although a retrofitting (optionally installed) device will be described here, it may be incorporated in a car or the like in advance. The opening conversion device 1 includes a state display device 10, an opening control unit 30, a display switching unit 40, an input connector unit 50, an output connector unit 60, a rotary first switch 70, and a button type. The second and third switches 80 and 82 and an OBD (On-board diagnostics) connector unit 90 are provided. The opening degree control unit 30 and the display switching unit 40 have a so-called functional configuration, and are realized by executing a predetermined program by a CPU or memory provided in the main controller 20 serving as a main body. .

  In this opening degree conversion device 1, the opening degree control unit 30 amplifies or attenuates an accelerator opening degree signal input via the input connector unit 50. Further, the opening degree conversion device 1 outputs a signal generated by amplification or attenuation (referred to herein as a pseudo accelerator opening degree signal) to the throttle control device via the output connector unit 60. As a result, the opening converting device 1 can transmit a pseudo accelerator opening signal different from the actual depression amount of the accelerator 98 to the engine side. That is, if the opening degree conversion device 1 is installed afterwards for a vehicle with a driving force such as an automobile or a two-wheeled vehicle, the operating level of the driving force with respect to the amount of depression of the accelerator can be converted.

  The status display device 10 is a device that transmits information to a user by using a light emission phenomenon, such as a liquid crystal display (LCD) or an organic EL display, and an LCD is used in this embodiment. As shown in FIG. 2, the state display device 10 includes an input display area 12, an output display area 14, a relative difference display area 15, a numerical value display area 16, a magnification display area 17, and a mode display area 18. The input display area 12 displays the input state of the opening degree conversion device 1 to the user. The “input state” means the state of the accelerator opening signal from the accelerator 98 that is input via the input connector unit 50.

  The output display area 14 displays the output state of the opening conversion device 1 to the user. This “output state” is, in principle, the state of the pseudo accelerator opening signal converted by the opening control unit 30, but in addition to this, the throttle opening information of the engine is directly detected and this throttle state is detected. The state of the opening information can also be used. The detection of the throttle opening information can be obtained by connecting the OBD connector unit 90 to the vehicle-side OBD output.

  The input display area 12 and the output display area 14 are strip-shaped areas 12a and 14a each including a plurality of rectangular unit windows 12b and 14b. In the present embodiment, 20 unit windows 12b and 14b are connected to each other, and the belt-like regions 12a and 14a formed thereby are designed to be curved in a partial arc shape. Accordingly, the display length of the band-like regions 12a and 14a is changed by switching the display number of the 20 unit windows 12b and 14b from 0 to 20. In addition, here, the output display area 14 is arranged outside the input display area 12, and these are arranged in parallel. As a result, the conversion amount of the pseudo accelerator opening signal with respect to the accelerator opening signal can be visually recognized by the relative difference between the display lengths (here, the difference in the display angle range in the arc shape).

  The relative difference display area 15 is a band-shaped area formed by a plurality of rectangular unit windows, and is arranged along the input display area 12 and the output display area 14. The relative difference display area 15 changes the display length of the input display area 12 and the output display area 14 by changing the display length of the relative difference display area 15 (here, the difference in the display angle range in the arc shape). Zoom in. This makes it easier to visually recognize even a small conversion amount.

  The numerical value display area 16 is arranged in an arc of the input display area 12 and the output display area 14, and can display Arabic numerals and English by a 7-segment method. The numerical display area 16 displays various information as necessary. The mode display area 18 is arranged at the bottom of the numerical display area 16 and has five types, NOR (normal mode), ECO (eco mode), SPORT (sport mode), SET1 (first customization), and SET2 (second customization). Lights up. The current driving mode can be visually displayed by this lighting state.

  As will be described later, the magnification display area 17 displays the display magnifications of the input display area 12 and the output display area 14 in five levels of 100%, 150%, 200%, 300%, and 400%.

  The rotary type first switch 70 and the button type second and third switches 80 and 82 are arranged in the casing 10 a of the state display device 10. When the rotary first switch 70 is rotated to one side, a plus input operation is performed, and when the first switch 70 is rotated to the other side, a minus input operation is performed. Although details will be described later, the conversion amount of the pseudo accelerator opening signal can be customized using, for example, the first switch 70. The second switch 80 is mainly used to switch various travel modes of the opening degree conversion device 1. The third switch 82 is used when performing initial setting, display magnification setting, and the like.

  The input connector unit 50 and the output connector unit 60 are integrated on the way via cables 50 a and 60 a and are connected to the main controller 20. The input connector unit 50 is connected to the accelerator unit connector 95 of the accelerator pedal 98. The output connector 60 is connected to a throttle connector 96 that controls the throttle of the engine. Although not particularly shown here, this output connector can be connected to an ECU (Engine Control Unit). When the opening conversion device 1 is not installed, the accelerator connector 95 and the throttle connector 96 are directly connected.

  Next, referring to FIG. 3, functional configurations of the opening degree control unit 30 and the display switching unit 40 of the main controller 20 will be described in more detail.

  The display switching unit 40 switches display contents of the status display device 10, and specifically includes a magnification switching unit 42 and a display mode switching unit 44. The magnification switching unit 42 switches the display magnifications of the input display area 12 and the output display area 14 in five stages of 100%, 150%, 200%, 300%, and 400%. For example, when the display magnification is 100% (normal magnification display), the range in which the accelerator depression amount (accelerator opening) is 0% (accelerator fully closed) to 100% (accelerator fully open) Display is performed using the total length of the region 12a. Further, when the display magnification is 200% (enlarged magnification display), the low-level range where the accelerator depression amount (accelerator opening) is 0% to 50% is the total length of the band-like region 12a of the input display region 12. Use to zoom in. For example, since the accelerator opening is often in the range of 0% to 50% during daily driving in a city or the like, the visibility of the state display device 10 is enhanced by enlarging and displaying only in this portion. Is possible. In this case, a range in which the accelerator depression amount (accelerator opening) is 50% to 100% cannot be displayed in the input display area 12, but for example, by duplicating the input display area 12, the length is doubled. If it can be secured, it can be displayed. Further, for example, the input display area 12 can be reset once when it exceeds 50%, and a range in which the accelerator opening is 50% to 100% can be newly displayed using the input display area 12. Since this display magnification is displayed in five levels in the magnification display area 17, the current screen setting can be visually recognized.

  In particular, when traveling in an area with relatively heavy traffic, it may be displayed at a magnification of 400%. In this case, only the low-level range where the accelerator depression amount is 0% to 25% can be displayed using the full length of the band-like region 12a of the input display region 12 at an enlarged magnification. The enlargement magnification is switched in order according to the amount of rotation of the first switch 70.

  The display mode switching unit 44 displays “travel mode display” for causing the state display device 10 to display the conversion state of the accelerator opening degree by the opening degree conversion device 1 during traveling, and the user's customization work status to the state display device 10. Switch the “setting mode display” to be displayed. Details of the running mode and the setting mode will be described later.

  The opening control unit 30 includes an accelerator opening detection unit 31, an accelerator opening conversion unit 32, a pseudo accelerator opening output unit 33, a conversion amount customization unit 34, and a travel mode switching unit 35. The accelerator opening detector 31 detects an accelerator opening signal input from the input connector unit 50. The accelerator opening conversion unit 32 amplifies or attenuates the accelerator opening signal to generate a pseudo accelerator opening signal. The pseudo accelerator opening output unit 33 outputs a pseudo accelerator opening signal to the output connector unit 60 side. The conversion amount customization 34 allows the user to arbitrarily set the amplification amount or attenuation amount of the accelerator opening signal performed by the accelerator opening conversion unit 32 according to preference. In the present embodiment, two types of customization setting results can be stored in any of the customization modes (SET1, SET2) using a memory such as an EPROM.

  The travel mode switching unit 35 sets the travel mode executed by the accelerator opening conversion unit 32 in addition to the above-described SET1 (first customization) and SET2 (second customization) as well as a preset NOR (normal mode: conversion). None), ECO (eco mode: attenuation conversion), SPORT (sport mode: amplification conversion).

  The graph of FIG. 4 illustrates the conversion amounts of NOR (normal mode), ECO (eco mode), and SPORT (sport mode) preset as initial values in the opening degree conversion device 1. The normal mode is a mode in which no amplification or attenuation is performed.

  In the eco mode, the accelerator opening signal is slightly amplified during the low level of 0% to 20%, but is greatly attenuated during the middle level of the accelerator opening signal of 20% to 60%. Further, when the accelerator opening signal is at a high level of 60% to 100%, it is attenuated at a value lower than the intermediate level. According to this eco mode, the fuel consumption is suppressed by attenuating the accelerator opening degree during steady running when the accelerator opening signal is at a medium / high level. On the other hand, at a low level at the moment of starting the vehicle, the accelerator opening signal is amplified to accelerate quickly. As a result, even in the eco mode, the stress felt by the driver can be reduced, so that a transient depression of the accelerator pedal can be avoided and an actual energy-saving operation can be realized. Note that if the accelerator opening is attenuated at a low level, which is the moment when the vehicle is started, the initial acceleration feeling becomes dull, which causes stress on the driver and instead depresses the accelerator. In this case, the eco mode has an adverse effect.

  The sport mode is somewhat amplified when the accelerator opening signal is at a low level of 0% to 20%, and greatly amplified while the accelerator opening signal is at an intermediate level of 20% to 60%. Further, when the accelerator opening signal is at a high level of 60% to 100%, it is amplified at a value lower than the intermediate level. Although the fuel consumption increases, the sport mode is a preferable mode when desiring to drive with improved engine responsiveness, such as in a mountainous area. The conversion amount of each mode is stored in a memory such as an EPROM.

  Upon receiving an instruction from the travel mode switching unit 35, the accelerator opening conversion unit 32 performs NOR (normal mode), ECO (eco mode), SPORT (sport mode), SET1 (first customization), SET2 (second customization). Based on one of the five driving modes, the accelerator opening signal is converted to generate a pseudo accelerator opening signal.

Next, a display example of the state display device 10 during traveling is shown in FIG. For example, while traveling in the eco mode, “ECO” in the mode display area 18 is lit. Further, in the input display area 12, the accelerator opening signal input to the opening converting device 1 is displayed in the band length (number of unit windows 12b. On the other hand, in the output display area 14, the accelerator opening degree is displayed. The pseudo accelerator opening signal converted in the eco mode by the conversion unit 32 is similarly displayed as the band length, so that the difference in the band length between the input display area 12 and the output display area 14 is the opening degree conversion. It becomes the conversion amount of the device 1. The driver can visually grasp the amount of depression of the accelerator and the conversion amount of the opening conversion device 1 in real time.

  Next, with reference to the flow of FIG. 6, the operation method of this opening degree converter 1 is demonstrated.

  When the power is turned on, the driving mode S100 is first set. In this travel mode S100, the five switches (NOR (S102), ECO (S104), SPORT (S106), SET1 (S108), and SET2 (S110)) are sequentially switched by pressing and holding the second switch 80. You can switch to This switching can be executed on condition that the accelerator opening is zero or the vehicle speed is zero.

  In any of these five types of travel modes S102 to S110, when the second switch 80 is pressed for a short time, the mode can be switched to the setting mode S200. In the setting mode S200, the conversion amount can be customized at a total of 20 setting points provided at intervals of 5% of the accelerator opening (S202). Specifically, when the second switch 80 is further pressed for a short time, the setting point can be changed to 0%, 5%, 10%... 90%, 95%, 100%. The user arbitrarily sets the amplification amount or the attenuation amount of the accelerator opening signal by rotating the first rotary switch 70 to the plus side or the minus side while moving the set point with the second switch 80. To go. In addition, when it changes from eco mode S104 to setting mode S200, it customizes from there on the basis of this eco mode S104. When transitioning to the setting mode S200, the display mode switching unit 44 also switches the state display device 10 in conjunction with “setting mode display”. In this “setting mode display”, as shown in FIG. 7, the current set point is displayed in the input display area 12, and the pseudo accelerator opening signal at each set point is displayed in the output display area 14. . The numerical value display area 16 displays the conversion ratio as a percentage. Therefore, the user customizes the conversion amount by the first switch 70 while visually grasping the input / output relationship by the status display device 10. When the arbitrary setting at all the setting points is completed (S204), a confirmation screen is displayed as to whether to save the change result in SET1 or SET2 (S206). After selecting SET1 or SET2, the setting is completed by further pressing the second switch 80, and the travel mode of SET1 or SET2 set this time is restored. As already described, at the time of customization, the sport mode can be changed as the upper limit value and the eco mode can be changed as the lower limit value. In other words, at each set point, an upper limit value on the amplification side and a lower limit value on the attenuation side are set, and it is not possible to customize beyond that.

  When the opening conversion device 1 is mounted on a vehicle, it is necessary to first set the accelerator range. In this case, the third switch 82 is long-pressed in the travel mode S100, and the process proceeds to the accelerator range setting mode S300. Note that this accelerator range setting mode can be changed only when the ignition key is ON and the engine is not started (that is, only energized). In the accelerator range setting mode 300, first, the third switch 82 is short-pressed without stepping on the accelerator at all. As a result, the opening control unit 30 detects the output value (voltage) of the accelerator opening signal from the accelerator 98 for a few seconds, and stores the average value therebetween in association with the accelerator opening 0% (S302). Next, the third switch 84 is pressed for a short time with the accelerator fully depressed. As a result, the output value (voltage) of the accelerator opening signal from the accelerator 98 is detected for several seconds, and the average value is stored in association with the accelerator opening 100%. As a result, the accelerator output value (voltage) depending on the vehicle type can be converted to an accelerator opening degree of 0% to 100%.

  When changing the display mode, the third switch 82 is short-pressed in the travel mode S100. When the third switch 82 is pressed once for a short time, the state transitions to the brightness adjustment mode S410. When the third switch 82 is pressed for a short time, the state transitions to the display magnification conversion mode S450. When the first switch 70 is rotated in the state of transition to the brightness adjustment mode S410, the brightness of the display screen changes in real time (S412). If the third switch 82 is further pressed for a short time after adjusting to the desired brightness, the travel mode S100 is restored with the adjusted brightness. Further, when the first switch 70 is rotated in the state of transition to the display magnification conversion mode S450, the display magnification changes in real time in the order of 100%, 150%, 200%, and 400% (S452). If the third switch 82 is pressed for a short time after changing to the desired magnification, the travel mode S100 is restored with the magnification unchanged.

  According to the opening changing device 1 of the present embodiment, the state display device 10 can simultaneously display the accelerator opening signal input from the accelerator 98 and the converted pseudo accelerator opening signal. Therefore, the driver can drive while visually comparing both signals. As a result, in the case of the eco mode, for example, an appropriate driving can be realized without depressing the accelerator too much.

  In particular, since the input display area 12 and the output display area 14 are band-like areas, the status display device 10 can visually recognize each signal quickly by changing its length. Furthermore, since the input display area 12 and the output display area 14 are arranged in parallel, the difference in length can be used as the conversion amount by matching the display ratios of the two. As a result, the user can quickly grasp the conversion amount. Further, since the input display area 12 and the output display area 14 are curved, it is possible to visually recognize in a familiar form like a so-called speedometer and rotation speed meter, so that convenience is improved.

  Further, in the opening changing device 1, the display magnification of the input display area 12 and the output display area 14 can be switched. As a result, the specific range in the accelerator opening signal can be enlarged and displayed on the screen according to the driving situation of the user. For example, when traveling in the city, the amount of depression of the accelerator pedal is about 0% to 30%, so it is more convenient to display the enlarged portion. Therefore, it can be said that it is particularly preferable to enlarge and display the low level side in the accelerator opening signal.

  Furthermore, in this opening degree conversion device 1, as the eco mode, when the accelerator opening signal is at a low level (at the initial speed), the accelerator opening signal is amplified to enhance the response, and thereafter the accelerator opening signal is At medium level (medium speed), the accelerator position signal is attenuated to improve fuel efficiency. When the accelerator position signal is high (at high speed), the accelerator position signal is Is also attenuated so that a sufficient speed can be obtained. In this way, by increasing the responsiveness of the engine at the initial speed, unnecessary accelerator work can be suppressed at the middle speed while providing a comfortable driving without stress. Although a case where amplification setting is performed at a low level in the eco mode is shown here, the present invention is not limited to this.

  Furthermore, the opening degree conversion apparatus 1 can customize the amplification or attenuation amount of the accelerator opening degree signal according to the user's preference. Therefore, the setting can be changed according to the traffic conditions of the road frequently used by the user. At this time, since an independent upper limit value and lower limit value are set for each set point in the amplification amount or attenuation amount that can be set by the user, the driving performance should not be deteriorated more than necessary due to incorrect settings. That's it.

  Further, even during the customization work, the input display area 12 displays each set point, and the output display area 14 displays the converted pseudo accelerator opening signal, so that the customized setting can be made visually.

  In the present embodiment, the input display area 12 and the output display area 14 are shown only when they are band-like areas that are partial arcs, but the present invention is not limited to this. For example, by rotating two types of needles such as a long hand and a short hand, it is also possible to visually display the conversion amount based on the rotation angle difference. In any case, the input display area 12 and the output display area 14 are displayed on the same scale, and these are arranged in parallel or superimposed so that the conversion amount can be transmitted visually. Is preferred. Of course, although the visibility is inferior, the input display area 12 and the output display area 14 display numerical values of the input value of the accelerator opening (for example, 30%) and the output value of the attenuated pseudo accelerator opening (for example, 28%), respectively. Then, the difference may be grasped.

  Further, in the present embodiment, the case where the opening degree conversion device 1 amplifies or attenuates the accelerator opening degree signal and changes the throttle opening degree of the engine serving as the internal combustion engine is shown, but the present invention is not necessarily applied to the internal combustion engine. It is not limited. For example, the present invention can be applied to a hybrid vehicle that uses a motor and a driving force of an internal combustion engine in combination, an electric vehicle that uses a driving force of only a motor, and the like. In this case, traveling in the eco mode is so-called power saving traveling.

  In the present embodiment, the case where the sport mode is set as the upper limit and the eco mode is set as the lower limit as the range in which the conversion amount of the accelerator opening can be customized is shown, but the present invention is not limited to this. It is also possible to use an upper limit value and a lower limit value arbitrarily set at each setting point. Further, in the present embodiment, the retrofit opening degree conversion device 1 has been described, but the present invention is not limited to this. On the other hand, it is needless to say that the retrofitting type is particularly preferable because the present apparatus can be introduced into automobiles of all existing vehicle types.

  Although not specifically shown in the present embodiment, the relative difference between the accelerator opening and the pseudo accelerator opening is integrated to calculate how much the fuel consumption has been reduced over a certain period. Anyway.

  It should be noted that the present invention is not limited to the above-described embodiment, and it is needless to say that various modifications can be made without departing from the gist of the present invention.

  According to the present invention, it is possible to provide an accelerator opening conversion device that can be applied to various driving engines and is highly convenient for the driver.
