The present invention relates to a low fuel consumption travel support device that supports the driving.

  In recent years, the user's awareness of fuel consumption has been increasing, and there is a tendency to prefer driving with lower fuel consumption. Patent Document 1 detects the driving operation of the driver, and changes the color and shape of the indicator displayed on the meter panel based on the driving state of the vehicle according to the driving operation, thereby giving the driver the current traveling state.

WO 2010/035440 (PCT / JP2009 / 004696)

  In Patent Document 1, an accelerator operation or a brake operation is detected as the driver's driving operation, and when the degree or frequency is high, it is determined that the fuel efficiency is not good, and for example, the indicator is lit with the corresponding display color. The driver is made to recognize that.

  However, the accelerator operation or the brake operation is an operation that is performed as needed during traveling including the degree and the frequency, and is an operation that is prioritized to the improvement of the fuel efficiency. Therefore, even if the driver is restricted with respect to the accelerator operation and the brake operation for the purpose of fuel consumption improvement, significant improvement in fuel consumption can not be expected.

  Further, the means (61) for determining the traveling state determines the non-low fuel consumption traveling state if none of the requirements are satisfied, and determines the first traveling state if only the first requirement is satisfied, and the first A second feature is that the vehicle is determined to be the second traveling state when the second requirement is further satisfied in the traveling state, and is determined to be the third traveling state when the third requirement is further satisfied in the second traveling state .

  Further, the means (62) for notifying comprises three indicators (51a, 51b, 51c), and turns off all the indicators in the non-low fuel consumption traveling state, and the first indicator (51a) in the first traveling state. Is turned on, the first and second indicators (51a, 51b) are turned on in the second traveling state, and the first, second and third indicators (51a, 51b, 51c) are turned on in the third traveling state. The point has a third feature.

Further, the means (62) for notifying comprises an asynchronous drive unit (621) for turning off each indicator asynchronously with the change of the running condition, and the asynchronous drive unit (621) has the third running condition. Even if at least one traveling state is jumped and changed from the state to the non-low fuel consumption traveling state , the lighting state of the indicator (51a, 51b, 51c) changes from the lighting state corresponding to the traveling state before the change. A fifth feature is that the light emission state corresponding to the later traveling state is sequentially changed.

  Further, the sixth feature is that the sequential change of the lighting state is performed at a time interval at which the rider can perceive each lighting state.

  A seventh feature resides in that the recommended deviation (Δv) of the vehicle speed is narrower than the recommended range (Δvrange).

  An eighth feature resides in that the three indicators are arranged in a line.

  Furthermore, between the speedometer (104) provided on the meter device (19) and the pair of left and right rear mirrors (6) in the vertical direction of the vehicle body of the vehicle (1), the three indicators (51a, 51b, 51c) There is a ninth feature in that it is disposed in

Therefore, anyone can realize low fuel consumption travel in a short time without forcing the rider to learn for a long time and to get used to it.

  According to a second feature, the means (61) for determining the traveling state determines the non-low fuel consumption traveling state if none of the requirements are satisfied, and the first traveling state if only the first requirement is satisfied.

  According to a fourth feature, in synchronization with the running state sequentially changing from the non-low fuel consumption running state to the first, second, and third running states, the lighting state of the indicator is from all off to all on. Since it changes sequentially up to now, it becomes possible to recognize the current driving condition in real time.

According to a fifth feature, the notifying means (62) comprises an asynchronous drive unit (621) for turning off each indicator asynchronously with the change of the running condition, and the asynchronous drive unit (621) runs Even if the state changes by jumping over at least one traveling state from the third traveling state to the non-low fuel consumption traveling state , the lighting state of the indicator (51a, 51b, 51c) is the traveling state before the change. Since the lighting state is sequentially changed from the corresponding lighting state to the lighting state corresponding to the changed driving state, the rider can recognize the transition state in which the driving state deteriorates in the non-low fuel consumption direction, and changes the driving state again. It can be a motivation to prevent deterioration and further improve fuel consumption.

  According to the sixth feature, since the sequential change of the lighting state is performed at a time interval at which the rider can perceive each lighting state, it is easy to be in the transition state in which the traveling state deteriorates in the non fuel saving direction. It will be recognizable.

A pair of left and right under cowls 32 are connected to both ends in the vehicle width direction of the low floor floor 12. The front side of the under cowl 32 in the vehicle body is connected to the lower end of the front side cover 8.

  The lower part of the seat 14 is covered by a seat cowl 13, and at the rear position of the low floor floor 12, a unit swing type power unit P integrally comprising an engine as a drive source and a transmission is pivotable. It is pivotally supported. A rear end portion of a power unit P rotatably supporting a rear wheel WR as a drive wheel is suspended from the vehicle body by a rear cushion 17.

  Referring to FIG. 2, the low fuel consumption driving support display panel 50 according to the present invention has upper end heights U of a pair of left and right rearview mirrors 6 to be checked backwards in the vertical direction when viewed from the viewpoint of rider R; It is disposed at the center of the vehicle width direction at a position between the meter device 19 and the height L of the speedometer that is most frequently viewed. More specifically, the low fuel consumption driving support display panel 50 is positioned closer to the top of the meter device 19 most visible to the rider R, and is disposed at a position where it can be recognized below the field of view even when the road surface in front is visually recognized. It is done.

  FIG. 3 is a front view of the meter device 19. As various indicators provided in a general two-wheeled meter device, left and right turn indicator lamps 101L and 101R, a high beam indicator 102, a position lamp 103, digital speed An LCD display panel 120 including a gauge 104 and an engine tachometer 105 and an LCD display panel 121 including a digital timepiece 106, an odometer 107 and a fuel gauge 108 are provided.

  In addition to these various indicators, the meter device 19 of the present embodiment is provided with a low fuel consumption driving support display panel 50 on the top of the display panel 120. On the low fuel consumption driving support display panel 50, along with the indication of "ECONOMY", three long fuel consumption traveling support indicators (ECONOMY indicators) 51a, 51b, 51c are arranged adjacent to each other in a horizontal row.

  FIG. 4 is a view showing the functions of the respective ECONOMY indicators 51a, 51b, 51c, and as shown in the first column that the vehicle speed is not in the low fuel consumption traveling state described later and in the "non fuel consumption traveling state". , Any of the indicators 51a, 51b, 51c are turned off.

  In addition, when the vehicle is in the “first traveling state” in which the vehicle speed falls within the vehicle speed range Δvrange with relatively good fixed area fuel efficiency, only the first indicator 51a is turned on, and the other indicators 51b and 51c are kept off.

  Furthermore, when the vehicle speed is within the vehicle speed range Δvrange and in the “second traveling state” which is a constant traveling state with less acceleration and deceleration, the second indicator 51b is also turned on in addition to the first indicator 51a, and the third indicator 51c Only keep the lights off.

  Furthermore, within the vehicle speed range Δvrange, the first and second indicators 51a and 51b are added to the first and second indicators 51a and 51b as the "third traveling state" in which the constant traveling state with less acceleration and deceleration continues for a predetermined time or more. The third indicator 51c also lights up. That is, all the ECONOMY indicators 51a, 51b, 51c light up.

  As described above, according to the present embodiment, since the low fuel consumption traveling can be realized only by controlling the vehicle speed, anyone can perform the low fuel consumption traveling in a short time without forcing the rider to learn or get used to it for a long time. . In addition, since the rider can visually recognize the degree of low fuel consumption traveling, the motivation to shift to the low fuel consumption traveling state can be enhanced.

  FIG. 5 is a functional block diagram of the low fuel consumption travel support device 100 for realizing the above low fuel consumption travel support. In the present embodiment, the low fuel consumption travel support device 100 is mounted on the meter device 19, and the configuration unnecessary for the description of the present invention is not shown here.

  The low fuel consumption driving support device 100 switches on / off the ECONOMY indicators 51a, 51b and 51c of the low fuel consumption driving support display panel 50, the one-chip microcomputer 52, and the low fuel consumption driving support display panel 50 respectively. As a main component, and is constantly supplied by a battery 38.

  The vehicle speed V is measured by detecting the rotational speed of the final gear 21 with the vehicle speed sensor 37. Power is supplied to the vehicle speed sensor 37 from the battery 38 via the ignition switch 22. The one-chip microcomputer 52 has a function as the traveling state determination unit 61 and a function as the traveling state notification unit 62.

  In the traveling state determination unit 61, the first requirement determination unit 611 determines whether or not the first requirement that the vehicle speed V is within the recommended range is satisfied. The second requirement determination unit 612 determines whether the second requirement that the deviation of the vehicle speed V is within the recommended deviation Δv is satisfied. The third requirement determination unit 613 determines whether the third requirement that the state in which the deviation of the vehicle speed V is within the recommended deviation Δv continues for a predetermined time or more is satisfied.

  The traveling state determination unit 61 determines the traveling state of the vehicle based on the determination results of the requirement determination units 611, 612, and 613. In the present embodiment, if only the first requirement is satisfied, the traveling state is determined to be the first traveling state. If the second requirement is further satisfied in the first traveling state, the traveling state is determined to be the second traveling state. Furthermore, if the third requirement is further satisfied in the second traveling state, the traveling state is determined to be the third traveling state. If none of the requirements are satisfied, the traveling state is determined to be the non-fuel-efficient traveling state.

  The traveling state notification unit 62 lights only the ECONOMY indicator corresponding to the determined traveling state or a combination thereof based on the determination result of the traveling state.

  In the present embodiment, the traveling state notification unit 62 includes the asynchronous drive unit 621 that turns off the indicators 51a, 51b, and 51c asynchronously with the change in the traveling state, and travels with a relatively small amount of fuel consumption. Even when the state (third or second traveling state) changes rapidly to a traveling state (first traveling state or non-low fuel consumption traveling state) in which fuel consumption is relatively large, the plurality of indicators are not turned off at the same time It is made to light-extinguish one by one sequentially behind the change of a state.

  6 and 7 are diagrams schematically representing the method of notifying the traveling state by the traveling state notification unit 62, and FIG. 6 shows the indicators 51a when the traveling state changes to the side where the fuel efficiency is improved, The lighting states of 51b and 51c are shown, and FIG. 7 shows the lighting states of the respective indicators 51a, 51b and 51c when the traveling state changes to the side where fuel consumption is deteriorated.

  First, referring to FIG. 6, the traveling state notifying unit 62 synchronizes with the change of the judgment result of the traveling state by the traveling state judgment unit 61 from the non-low fuel consumption traveling state to the first traveling state at time t1. Then, only the first indicator 51a is lit. Similarly, when the determination result of the traveling state changes from the first traveling state to the second traveling state at time t2, the second indicator 51b is further lighted in synchronization with this change. Similarly, when the determination result of the traveling state changes from the second traveling state to the third traveling state at time t3, the third indicator 51c is further lighted in synchronization with this change.

  As described above, in the present embodiment, when the traveling state changes to the side where the fuel efficiency improves, the indicators 51a, 51b, and 51c are driven and lighted in synchronization with the change. As a result, it is possible to quickly notify the rider that the traveling state is shifting to the low fuel consumption side, and the motivation for the low fuel consumption traveling can be enhanced.

  Next, referring to FIG. 7, the traveling state notifying unit 62 synchronizes with the change of the determination result of the traveling state by the traveling state determination unit 61 from the third traveling state to the second traveling state at time t4. Thus, only the third indicator 51c is turned off. Similarly, when the determination result of the traveling state changes from the second traveling state to the first traveling state at time t5, the second indicator 51b is further extinguished in synchronization with this change. Similarly, when the determination result of the traveling state changes from the first traveling state to the non-fuel-efficient traveling state at time t6, the first indicator 51a is further extinguished in synchronization with this change, whereby all the indicators are extinguished. Do.

  However, in the present embodiment, since the continuation of the second traveling state is regarded as the satisfaction of the third traveling state, the satisfaction of the third traveling state is not satisfied and the satisfaction of the second traveling state is also satisfied. It disappears. As a result, when transitioning from the state in which the three indicators are lit to the non-low fuel consumption direction, the ideal step-off as shown in FIG. 7 is not realized, and the third indicator 51c and the second indicator at time t4. 51b will turn off simultaneously.

  More specifically, as shown in FIG. 8, when transitioning from the state in which the three indicators are lit to the non-low fuel consumption direction, the determination result of the traveling state is the third traveling state from the third traveling state at time t4. It will change at once to the driving condition. On the other hand, in the present embodiment, the asynchronous drive unit 621 turns off only the third indicator 51c at time t4, and also turns off the second indicator 51b at time t5 after a predetermined time has elapsed, thereby the traveling state. The lighted state of the indicator is made to follow asynchronously and sequentially in response to the rapid change of. The predetermined time is a time in which the rider can sufficiently perceive each lighting state, and can be set to, for example, about 1 sec to 5 sec.

  In the present embodiment, a predetermined time (first predetermined time) from turning off the third indicator 51 c to turning off the second indicator 51 b is set as short as possible within a range in which the rider can perceive. Here, in general, a human tends to prefer an intermediate level, and even for the indicator according to the present embodiment, "the first indicator 51a alone is not eco-friendly, but the second indicator 51b is on. If it looks like it's more than half, it's probably eco. ” In the present embodiment, by setting the first predetermined time (the time during which the second indicator 51b is on) short, it is possible to enhance the motivation to turn on the second indicator 51b. In the present embodiment, since the continuation of the second traveling state is set as the establishment condition of the third traveling state, it is possible to lead the rider to the driving in the third traveling state.

  Further, in the present embodiment, the lighting time (second predetermined time) of the second indicator 51b is set to be short also when transitioning from the non-low fuel consumption state to the low fuel consumption direction. According to this setting, when the second indicator 51b is turned on, an impression is given that the third indicator 51c is also immediately turned on, and the motivation to turn on the third indicator 51c is enhanced, and as a result, the rider is It becomes possible to lead to the driving in 3 driving state.

  As shown in FIG. 9, when the determination result of the traveling state changes from the second traveling state to the non-low fuel consumption traveling state at a dash at time t4, the asynchronous drive unit 621 turns off only the second indicator 51b at time t4. At time t5 after the elapse of a predetermined time, the first indicator 51a is also turned off, so that the lighting state of the indicator asynchronously sequentially follows the rapid change of the traveling state. However, in the present embodiment, the satisfaction condition of the third traveling condition is not satisfied, and the satisfaction condition of the second traveling condition is not satisfied, so the aspect as shown in this figure is difficult to realize.

  As shown in FIG. 10, even when the determination result of the traveling state changes from the third traveling state to the non-low fuel consumption traveling state at a dash at time t4, the asynchronous drive unit 621 only has the third indicator 51c at time t4. Is turned off, and the second indicator 51b is also turned off at time t5 after a predetermined time has passed, and the first indicator 51a is also turned off at time t6 after the predetermined time has passed, thereby providing an indicator for the traveling state Makes the lighting state of the light follow asynchronously sequentially.

As described above, in the present embodiment, when the traveling state changes to the side where the fuel efficiency improves, the lighting of each indicator 51a, 51b, 51c is controlled in synchronization with the change. On the other hand, when the running condition changes to the side where fuel consumption is deteriorated, the lighting of each indicator 51a, 51b, 51c is not synchronized with the change of the running condition, and the running condition drops several stages at a time. Each indicator is turned off sequentially at a time interval at which the rider can perceive each lighting state.

  Therefore, the rider can recognize a transient state in which the traveling state degrades in the non-low fuel consumption direction, and the traveling state can be renewed to prevent the deterioration of the fuel consumption and to further motivate the fuel consumption to be improved.

  In the above embodiment, only the vehicle speed V is used as a parameter, and the traveling state is determined based on the value, the range, the deviation, and the duration, but the present invention is not limited to this. It may be added to the parameter that the current ignition timing is within the retardation control range on the ignition map.

That is, the ignition timing of the engine, in the engine speed is relatively low rotational speed range, and tend to be retarded angle control when the load factor of the engine is in a low state, the retard control condition and Teichi A correlation is recognized with the running condition with excellent fuel efficiency. Therefore, by adding the fact that the ignition timing is under retard control as a parameter, it is possible to reflect the load condition of the engine that can not be distinguished from the vehicle speed V alone in the traveling condition determination. It should be noted that this retardation control state may be added to the determination condition of the first traveling state.

  Further, in the above embodiment, three horizontally long indicators 51a, 51b, 51c are described as being arranged adjacent to each other in one horizontal row, but the present invention is not limited to this, and sufficient in the horizontal direction If space can not be secured, three horizontally long indicators may be arranged in a vertical row.

  If sufficient space can not be secured both in the vertical direction and in the horizontal direction, as shown in FIG. 11, the three indicators 51a, 51b, 51c may be formed in a ring shape and these may be arranged concentrically. good. According to this arrangement, three indicators can be provided to the meter device which can not secure a sufficient space in the lateral direction.

Alternatively, the indicator 51a, 51b, 51c and composed of a single indicator, its brightness may be changed in accordance with brightness or color in the running state.

Furthermore, in the above embodiment, each indicator is constituted by a single segment, but the present invention is not limited to this, and each indicator is divided into a plurality of segments as shown in FIG. Within each indicator, each segment is sequentially staggered,

  In this way, the elapsed time of each traveling state can be recognized, and in particular, as in the transition from the second traveling state to the third traveling state, the elapsed time in the second traveling state is used as an index. In that case, it will be possible to boost their motivation.

  The present invention comprises an indicator representing a plurality of levels, wherein the intermediate level indicator changes to an adjacent indicator after a predetermined time has elapsed. The present invention lights the indicator if the condition of the first traveling state is satisfied even if a sudden speed change occurs from the third traveling implementation state. The first traveling state is set to a speed range of about several tens of km / h, and the indicator can be illuminated relatively easily. Therefore, at least one eco-indicator easily lights up, it is easy to make rider R conscious, and it is easy to lead to eco-driving.

  Although the embodiment described above is described using three indicators, the number of indicators may not be three. For example, four or more or two or less may be used. In addition, each state may be represented by a picture or an icon with a segment liquid crystal or a full dot TFT liquid crystal.
