Description

  The present invention relates to a vehicle information system and the like.

  In Patent Document 1, the meter_ECU calculates the instantaneous fuel consumption Fci of the vehicle based on the travel distance Li and the fuel injection amount Fi within the set time t, and the travel distance Li and A configuration is disclosed in which the average fuel consumption Fc of the vehicle is calculated based on the integrated values L and F of the fuel injection amount Fi, and the deviation of the instantaneous fuel consumption Fci from the average fuel consumption Fc is displayed on the fuel consumption meter as fuel consumption information. This display is performed by swinging the pointer with respect to the neutral position on the fuel consumption meter. When the deviation is positive, the pointer is swung in the plus direction with a swing width corresponding to the deviation amount, and when the deviation is negative, the pointer is moved by the deviation amount. This is done in such a way that it swings in the minus direction with a swing width according to the. In addition, the “region” where the pointer swings is displayed in different colors in the plus direction and the minus direction.

JP 2007-298494 A

  However, the pointer specifies the value according to the position indicated by the needle tip. That is, there is a problem that the value is indicated by a point indicated by the needle tip, and it may be difficult to visually recognize at a glance. For example, it is easy to be affected by the inclination of the vehicle traveling, and the magnitude and direction of the deviation may be mistaken for the inclination of the vehicle.

  In addition, it is necessary to know in advance what the position indicated by the needle tip indicates. For example, as shown in FIG. 14 of Patent Document 1, the user needs to know in advance in what region the degree of deterioration from the average fuel consumption and the improvement. Further, in Patent Document 1, the color of the area (scale color) is changed between the plus side and the minus side, and it is possible to determine whether or not the driving is in the direction with good fuel efficiency by looking at the color of the area indicated by the pointer. However, there is a problem in that it is not always possible to know at a glance how much the fuel consumption is worsening than the average fuel consumption by simply coloring the point indicated by the needle tip. In particular, there is a problem that the guideline may be difficult to see when it is dark such as at night.

  Accordingly, the present invention has been made to solve such a problem, and provides a vehicle information display system and the like that makes it easier for the driver to understand the deviation of the current value from the reference value of the vehicle information at a glance than before. With the goal.

  (1) In order to achieve the above-described object, the vehicle information display system according to the present invention acquires vehicle information, and uses the reference value for the vehicle information as a reference position, the reference value of the current value of the vehicle information. A vehicle information display system that displays a deviation from the reference position as a deviation from the reference position, and performs a fill display that displays a deviation of the current value from the reference value in a predetermined fill mode from the reference position. The color is mainly a first color with respect to the positive direction with respect to the reference value, and a second color different from the first color with respect to the negative direction with respect to the reference value. To do.

  The vehicle information may be acquired from the vehicle by connecting to the in-vehicle LAN, for example, or may be acquired by providing a sensor or the like in the vehicle, or a sensor or the like is provided in the vehicle information display system. You may make it acquire.

  For example, the reference value may be an average value, a median value, or a mode value of a plurality of current values acquired in the past. As described later (14), it is particularly preferable that the reference value is an average value for a predetermined period of the acquired vehicle information, and the current value is an instantaneous value.

  When the reference value is calculated based on a plurality of current values acquired in the past, the range of the current value used for the calculation may be a value for a predetermined period. The start of the predetermined period may be, for example, when the vehicle information display system is attached to the vehicle, may be from a specific time, may be from a time before the predetermined period from the present, or a user such as a driver. It may be from the time when there is an instruction from. Further, the end of the predetermined period may be, for example, the present, may be before the predetermined period from the present, or may be a specific time after the start, or when there is an instruction from a user such as a driver. It may be from. The predetermined period may be, for example, yesterday, last month, or the previous year, but if the final period is current, it is easy to understand because it is a reference value reflecting the value from the present to the predetermined period, When the vehicle information display system is attached to the vehicle or when an instruction from a user such as a driver is given at the beginning, it is easy for the user to understand.

  The deviation of the current value from the reference value may be a value obtained by subtracting the reference value from the current value, for example.

  The predetermined filling mode from the reference position may be solid or may be a predetermined pattern such as hatching. In particular, the predetermined filling mode may be a predetermined continuous pattern or a repetitive pattern, and in particular, it may be a single color. Further, the larger the deviation is, the better it is possible to display in the predetermined painting mode from the reference position to a position farther away.

  “Mainly the first color” and “mainly the second color” are intended to indicate that a plurality of colors may be used as well as a single color fill. The first color is different from the second color. In particular, the first color and the second color are preferably colors whose hues are not approximate, and are particularly preferably colors that are substantially complementary.

  The display means for displaying the deviation may be a display device that displays in a fixed pattern in advance, but if a color dot matrix display device is used, it is particularly good because the display content such as the fill mode can be made flexible, It is particularly preferable to use a display that changes the transmissivity and reflectivity of external light by a backlight, a front light, etc., such as a liquid crystal display, or a self-light-emitting display, such as an EL display. In this way, the deviation can be easily visually recognized even in a dark environment such as at night. When a color dot matrix display device is used, the fill width may be one dot or a plurality of dots.

  The configuration of Patent Document 1 only changes the color of the area (the color of the scale) on the plus side and the minus side, and the width of each area is fixed and does not change according to the deviation, which is difficult to understand. In this way, the magnitude of the deviation from the reference value can be easily grasped at a glance as the size of the range filled from the reference position.

  In addition, unlike the needle, even if there is an inclination due to the traveling of the vehicle, the size of the range painted from the reference position does not change, so that the magnitude and direction of the deviation are not erroneously recognized due to the inclination of the vehicle.

  The vehicle information display system may be configured to be fixable to the vehicle. The structure that can be fixed to the vehicle may be, for example, a structure provided with means for directly fixing to the vehicle, or indirectly fixed to the vehicle such as a structure having means for fixing to the vehicle fixing means (for example, a bracket). The structure provided with the means to do may be sufficient. The fixed place is preferably in the passenger compartment, and is preferably a position that can be visually recognized by the driver. For example, it is good to set it as the structure fixed with respect to a dashboard or a windshield. As a structure to fix, you may make it stick with an adhesive agent, a double-sided tape etc., for example, and you may make it adsorb | suck and fix with a suction cup etc.

  (2) It is preferable that a third color different from the color in the plus direction and the color in the minus direction is mainly configured to indicate the reference position.

In this way, the reference position can be clearly grasped at a glance, the displacement direction from the reference position can be easily grasped, and the size of the filled area from the reference position can be grasped at a glance. be able to.
In the embodiment, the first color is blue, the second color is red, and the third color is white.

  (3) A plurality of blocks having a predetermined shape to be filled are arranged toward a position away from a position close to the reference position, the plurality of blocks have the same or similar shape, and the block is filled with the predetermined fill mode. In the state of not displaying in (4), it is preferable that the fourth color different from the color to be painted is mainly displayed in a painted state.

  In this way, it is possible to grasp at a glance from where to where the painting is performed, and relatively easily grasp the size of the painting.

  For example, in the embodiment, the blocks are vertically rectangular and have the same shape, and the positions to be moved away are the left and right ends, and the fourth color is painted in advance in gray.

(4) It is preferable to display 10 or more blocks in the plus direction and 10 or more blocks in the minus direction. In this way, the degree of deviation of the current value with respect to the reference value can be known in more detail.
For example, in the embodiment, the number of blocks is 12 in both the plus direction and the minus direction.

  In particular, the number of blocks may be the same in the plus direction and the minus direction. Further, for example, the same number of blocks having the same shape centered on the reference position may be arranged on the same straight line at the same interval in a direction away from the reference position. In this way, the degree of the deviation from the reference value can be easily grasped at a glance depending on how far the display is filled from the center position of the plurality of arranged blocks.

  (5) Complement that gradually cancels the fill display or the fill display from the position before the change to the position after the change when the range of the fill display changes according to the predetermined fill mode with the change of the deviation In the complementary display, the fill display from the reference position when the deviation is changed in a larger direction may be performed earlier than the fill release display when the change is changed in a smaller direction. .

  In the embodiment, the complementary display in the direction in which the deviation increases is performed relatively earlier than the complementary display in the direction in which the deviation decreases, and the complementary display (release display) in the direction in which the deviation decreases in the direction in which the change increases. It is relatively slow compared to the complementary display.

(6) It is good to set it as the structure which displays the position of the edge part of the said fill display from the said reference position corresponding to the maximum value of the said several deviation over the predetermined time long compared with the acquisition interval of the said present value. In this way, for example, the maximum value among the current values at a plurality of different times acquired within a continuous predetermined time can be grasped in relation to the reference position, and the magnitude between the maximum value and the current value is determined. You can grasp the relationship at a glance. It is also possible to easily determine whether or not the current value has exceeded the maximum deviation within the predetermined time.
The position of the end of the fill display may be displayed by, for example, filling a line or a block of a predetermined color (fifth color).

(7) The vehicle information may be a value that changes according to a user's vehicle operation, the deviation calculation interval may be 1 second or less, and the fill display may be performed according to the calculation interval.
In this way, the user's current vehicle operation can be grasped in real time at a glance.

(8) The deviation calculation interval may be the same as the refresh rate of the display screen.
In this way, it is possible to display smoothly. Preferably, the update is performed several times to several tens of times per second.

  (9) The filled display history may be displayed for at least the past several minutes. In this way, it is possible to confirm the transition of the past deviation and to confirm the history of the past deviation and the current deviation in comparison.

  (10) The history may be displayed by scrolling past past display locations so that the fill display corresponding to the current value is performed with a certain position as a reference position.

For example, in the embodiment, the right end of the graph is fixed as the position of the fill display corresponding to the current value, and the deviation of the current value is displayed in the vertical direction from the right end. I am doing so.
In this way, it is possible to easily check the deviation from the present to the past for a certain period of time, and to grasp the current value at a glance.

  (11) The peak point of the fill display in the history display may be highlighted.

  In this way, it is possible to easily confirm the maximum deviation value in the history display, and to easily confirm the level of deviation of the current value with respect to this peak point. it can.

  (12) In the history display range, it is preferable to display the ratio regarding the plus-direction painted area and the minus-filled area together with the history display.

  In this way, it is possible to easily grasp whether the current value relative to the reference value is good or bad within the history range. In this case, for example, the range of information used for calculating the reference value may be a range that exceeds the range displayed as history, and in particular, the range of information used for calculating the reference value is 10 times or more than the range displayed as history. It is good to make it the range which becomes a lot of information.

The ratio of the plus direction fill area and the minus direction fill area may be, for example, the ratio of the plus direction fill area itself and the minus direction fill area itself, or the current value obtained for performing this fill. It is good also as ratio of the integral value of the magnitude | size of each log | history of the plus direction of the deviation from the reference value of a value, and a minus direction.
The ratio may be displayed as a numerical value, or a line or the like may be drawn on the history according to the ratio.

(13) The vehicle information may be obtained from an acquisition unit, and when vehicle information cannot be acquired from the acquisition unit, a solid display based on the vehicle information is not performed.
(14) The reference value may be an average value for a predetermined period of the acquired vehicle information, and the current value may be an instantaneous value.

  The average value of the acquired vehicle information for a predetermined period may be, for example, the instantaneous value of the vehicle information acquired and the average value of the acquired vehicle information for the predetermined period may be acquired, or the average value itself may be acquired as the vehicle information It is good also as an average value of the predetermined period of vehicle information acquired by doing.

  As the instantaneous value, for example, an average value for a period shorter than the average value may be used. In this case, it is preferable to use an average value of time intervals shorter than a time interval that can be recognized by a person, such as 1 second or less. The instantaneous value may be obtained by obtaining vehicle information defined as the instantaneous value from the vehicle. For example, vehicle information defined as instantaneous fuel consumption may be acquired from the vehicle and used.

(15) The reference value may be an average fuel consumption, and the current value may be an instantaneous fuel consumption.
The components (1) to (14) may be appropriately combined.

  (16) The vehicle information display system according to any one of (1) to (15) may be configured as a program for causing a computer to realize the function.

This green fill is a fill with gradation that lowers the luminance from the top to the bottom of the block.

  For example, in the bar graph of the engine speed, when the engine speed is 0 rpm, all the blocks are filled with a single gray color without being filled with green. If it exceeds 0 rpm, the blocks are painted in green one by one from the left every 256 rpm. When the engine speed exceeds 0 rpm and reaches 256 rpm, only the first block (the leftmost block) is displayed in green, and when the engine speed exceeds 256 rpm and reaches 512 rpm, the first block is displayed. The second block is filled and displayed, and when the engine speed is over 512 rpm and up to 768 rpm, the first, second and third blocks are filled and displayed. Each block is painted green, and if it exceeds 6145 rpm, all blocks from 1 to 25 are painted green and displayed.

Also, in the engine load factor bar graph, when the engine load factor is 0%, all the blocks are filled with a single gray color without being filled with green. If it exceeds 0%, the blocks are painted in green one by one from the left every 4%. When the engine load factor is a value exceeding 0% to 4%, only the first block (the leftmost block) is displayed in green, and the engine load factor is a value exceeding 4% to 8%. Sometimes the 1st and 2nd blocks are filled and displayed, and when the engine load factor is over 8% and up to 12%, the 1st, 2nd and 3rd blocks are filled and displayed. Each block is painted in green one by one from the left, and if it exceeds 96%, all blocks from No. 1 to 25 are painted in green and displayed.
Similarly to the engine load factor, the throttle opening is also displayed in blocks from 1 to 25 corresponding to the range of 0 to 100%.

  The bar graph of the instantaneous fuel consumption display area according to the present invention has a different configuration from the above-described bar graph of engine speed, bar graph of engine load factor, and bar graph of throttle opening.

  In the instantaneous fuel consumption bar graph 50, as shown in a partial excerpt in FIG. 6, the thirteenth block, which is the central block of the 25 blocks, is always displayed in white. This 13th white block is displayed as a reference position. This reference position indicates the average fuel consumption, and the average fuel consumption is an average value of instantaneous fuel consumption obtained every second from the time when the radar detector is attached to the vehicle to the present. Then, as shown in FIGS. 6B and 6C, the deviation of the latest instantaneous fuel consumption value acquired this time, which is the current value with respect to the average fuel consumption, is displayed as a bar graph in the left or right direction from the reference position. To do. When the deviation (latest instantaneous fuel consumption−average fuel consumption) is positive, that is, when the latest instantaneous fuel consumption is better than the average fuel consumption, as shown in FIG. The number of blue fills corresponding to the deviations are displayed in order from the reference position. The blue fill display is a solid blue display. When the deviation (latest instantaneous fuel consumption-average fuel consumption) is negative, that is, when the latest instantaneous fuel consumption is worse than the average fuel consumption, as shown in FIG. The number of red fills corresponding to the deviation are displayed in order from the reference position in the first direction). The red fill display is a solid red display with a single red color.

  The number corresponding to the deviation is 0 when the deviation is 0, and when the deviation is positive, it is the number of the latest instantaneous fuel economy / average fuel economy value (rounded down), when the deviation is negative. Is the number of average fuel economy / latest instantaneous fuel economy value (rounded down to the nearest decimal place). Therefore, when the latest instantaneous fuel consumption coincides with the average fuel consumption (when the deviation is 0), all blocks No. 1 to 12 and No. 14 to 25 are filled with a single gray color.

  For example, when the average fuel consumption is 10 km / l and the latest instantaneous fuel consumption exceeds 10 km / l, the right block from the reference position corresponding to the number of the latest instantaneous fuel consumption / 10 values (rounded down to the nearest decimal point) (13 (Blue from right) Therefore, when the latest instantaneous fuel consumption is 10 km / l or more and less than 20 km / l, the 14th block is displayed in blue, and the blocks 1 to 12 and 15 to 25 are displayed in gray. When the latest instantaneous fuel consumption is 20 km / l or more and less than 30 km / l, the 14th and 15th blocks are displayed in blue, and the blocks 1 to 12 and 16 to 25 are displayed in gray. When the latest instantaneous fuel consumption is 30 km / l or more and less than 40 km / l, the 14th, 15th and 16th blocks are displayed in blue, and the 1st to 12th and 17th to 25th blocks are displayed in gray. And Similarly, every time 10 km / l is increased, the blocks are painted blue one by one from the left. As a result, when the latest instantaneous fuel consumption is 120 km / l or more, blocks No. 14 to No. 25 are displayed in blue.

  On the other hand, for example, when the average fuel consumption is 10 km / l, and the latest instantaneous fuel consumption is less than 10 km / l, the block (No. 12) on the left side of the reference position corresponding to the number of 10 / latest instantaneous fuel consumption (rounded down) To the left side). For example, if the latest instantaneous fuel consumption is 5 km / l, 10/5 = 2 blocks (blocks 12 and 11) are displayed in blue, and blocks 1 to 10 and blocks 13 to 25 are displayed. Is filled with gray. For example, when the latest instantaneous fuel consumption is 2.5 km / l, 10 / 2.5 = 4 blocks (12th, 11th, 10th, and 9th blocks) are displayed in red, and 1 The blocks No. 8 to No. 13 and No. 13 to No. 25 are displayed in gray. When the latest instantaneous fuel consumption is 1.25 km, 10 / 1.25 = 8 blocks (12th, 11th, 10th, 9th, 8th, 7th, 6th, 5th blocks ) Is displayed in red, and blocks 1 to 4 and 13 to 25 are displayed in gray. In this way, as the latest instantaneous fuel consumption approaches 0, a larger number of blocks on the left side from the reference position are displayed in red.

  Next, the drawing process of the 2nd vehicle information display screen by a 2nd vehicle information display function is demonstrated. As shown in FIG. 7, the second vehicle information display screen includes an instantaneous fuel consumption display area, a highway average display area, a general road average display area, and an all road average display area in order from the top to the bottom on the left side. A graph display area is provided. In the instantaneous fuel consumption display area, expressway average display area, general road average display area, and all road average display area, the name of each vehicle information is displayed in the upper left and the unit of the value is displayed in the upper right. This area displays the value under the character.

  The instantaneous graph display area includes a reference line, a grid line, a history value bar, and a current value bar. The reference line is a white line drawn in the horizontal direction at the center in the vertical direction. The reference line is composed of 180 dots. If the right end of the reference line is the first dot and the left end is the 180th dot, the grid lines are the 10th, 30th, 50th and 70th dots. , 90th dot, 110th dot, 130th dot, 150th dot, 170th dot, and so on, from the 10th dot to the 170th dot at 20-dot intervals, drawn in yellow in the vertical direction with a width of 1 dot . In addition, the current value bar is a line drawn in one of the upper and lower directions of the first dot, and when the current fuel consumption exceeds the average fuel efficiency when the reference line is the average fuel efficiency, that is, the deviation (instantaneous fuel consumption-average When the fuel efficiency is positive, a blue line with the number of dots corresponding to the deviation is drawn upward from the reference line, and the current latest instantaneous fuel consumption is lower than the average fuel consumption, that is, the deviation (instantaneous fuel consumption-average fuel consumption) When is negative, a red line having the number of dots corresponding to the deviation is drawn downward from the reference line. The width of the red line and the blue line is 1 dot. Further, the maximum value in the upward direction of the number of dots corresponding to the deviation value is the number from the dot adjacent to the upper direction of the reference line on the grid line to the dot positioned at the upper end of the grid line. The number of dots corresponding to the deviation is set to 0 dots when the deviation is 0, and is substantially the same as when the instantaneous fuel consumption display area of the first vehicle information display screen of FIG. The number of dots of the latest instantaneous fuel consumption / average fuel consumption value (rounded down) is used, and if the deviation is negative, the average fuel consumption / latest instantaneous fuel consumption value (rounded down) is the number of dots.

  Then, when the next latest instantaneous fuel consumption value is acquired one second after the latest instantaneous fuel consumption value is acquired, the deviation in the vertical direction from the first dot in the horizontal direction to the 179th dot on the reference line is deviated. The line drawn with the number of dots corresponding to is drawn at the position moved to the left by 1 dot, and then the scroll display is performed to draw the line with the number of dots corresponding to the deviation of the latest instantaneous fuel consumption at the 180th dot. . In this way, the deviation from the average fuel consumption of the latest instantaneous fuel consumption is always displayed at the first dot, and from the second dot to the 180th dot, the moment from the average fuel consumption at the time of obtaining the instantaneous fuel consumption in the past. The deviation in fuel consumption is displayed as a history. Since redrawing is performed every second in this way, 180 seconds (3 minutes) are displayed as the history.

  As described above, the radar detector, which is the vehicle information display system according to the present invention described as the first vehicle information display function and the second vehicle information display function, acquires the instantaneous fuel consumption as vehicle information and acquires it as a reference value for the instantaneous fuel consumption. Vehicle information display system that displays the deviation from the average fuel consumption of the latest instantaneous fuel consumption value as the current position as the deviation from the reference position, with the average fuel consumption that is the average value from the installation of the instantaneous fuel consumption to the present as the reference position It is. Then, a fill display is performed in which a deviation of the latest instantaneous fuel consumption from the average fuel consumption is displayed in a predetermined filling manner from the reference position. The fill color is mainly blue, which is the first color for the positive direction with respect to the average fuel consumption, and red, which is the second color different from the first color, for the negative direction with respect to the average fuel consumption. Is mainly.

  By the display process as described above, the deviation of the current instantaneous fuel consumption from the reference average fuel consumption can be easily grasped at a glance as the direction and color filled from the reference position and the size of the range. be able to. In addition, unlike the needle, even if there is an inclination due to the traveling of the vehicle, the size of the range painted from the reference position does not change, so that the magnitude and direction of the deviation are not erroneously recognized due to the inclination of the vehicle.

  In the present embodiment, the reference position is indicated by being filled with white, which is a third color different from blue, which is a positive color, and red, which is a negative color. Therefore, the reference position can be clearly understood at a glance by the difference in color, the displacement direction from the reference position can be easily grasped, and the size of the filled area from the reference position can be grasped at a glance. be able to.

  In this embodiment, as shown in FIGS. 5 and 6, a plurality of rectangular blocks to be filled are arranged toward a position away from a position close to the reference position, and the plurality of blocks have the same shape. In a state where this block is not displayed in the predetermined filling mode, the block is displayed in a state of being painted in gray, which is a fourth color different from the color to be painted. Accordingly, it is possible to grasp at a glance from where to where the painting is performed, and relatively easily grasp the size of the painting.

  In the present embodiment, since 12 blocks are displayed in the positive direction and 12 blocks in the negative direction, the degree of deviation of the latest instantaneous fuel consumption from the average fuel consumption can be known in detail. In particular, in the present embodiment, since the number of blocks is the same in the plus direction and the minus direction, it is easy to grasp the reference position. Furthermore, in the present embodiment, the same number of blocks having the same shape centered on the reference position are arranged on the same straight line in the direction away from the reference position at the same interval, so that the center positions of the plurality of blocks arranged The degree of the deviation from the average fuel consumption can be easily grasped at a glance depending on how far the display is filled.

  In this embodiment, the instantaneous fuel consumption is acquired and displayed as vehicle information, but the instantaneous fuel consumption is a value that changes according to the accelerator operation of the user. Then, the deviation calculation interval is set to 1 second, and the filled-in display is performed at the calculation interval. Therefore, the driver can grasp at a glance the quality of the current accelerator operation at a glance.

  In this embodiment, the average fuel consumption is the average value of the acquired instantaneous fuel consumption up to the present value, but the average fuel consumption itself may be acquired from the ECU of the vehicle as vehicle information and may be used as the average fuel consumption. . In the present embodiment, the instantaneous fuel consumption is a value output as the instantaneous fuel consumption from the ECU of the vehicle. However, for example, an average value of the instantaneous fuel consumption for a period shorter than the average fuel consumption may be used. In this case, it is preferable to use an average value of time intervals shorter than a time interval that can be recognized by a person, such as 1 second or less.

  In the present embodiment, the vehicle information is acquired from the ECU of the vehicle by connecting to the in-vehicle LAN or the like from the failure diagnosis connector. However, the vehicle information may be acquired by providing a sensor or the like in the vehicle. You may make it acquire by providing a sensor etc. in a machine.

  In the present embodiment, the reference value is the average fuel consumption, but may be a median value or a mode value of a plurality of instantaneous fuel consumptions acquired in the past, for example. Further, the reference value may be obtained by removing the exception value or weighting.

  In this embodiment, the average fuel consumption is calculated based on a plurality of instantaneous fuel consumption acquired in the past, and the period (range) of the instantaneous fuel consumption used for the calculation is acquired from when the radar detector is attached to the vehicle to the present. For example, the beginning of this period may be from a specific time, from one year before the present, or from one month before the present. Good. The period may be this week or this month. Alternatively, it may be from the time when an instruction by operating the remote controller 17 is detected from a user such as a driver. Further, the end of this period may be the current as in the present embodiment, for example, or may be a predetermined period before the current value, for example, up to the current previous value (one second before the current value). And it is good also as the specific time after an initial stage, or it may be from the time of detecting operation by operation of remote control 17 from users, such as a driver. The period may be, for example, yesterday, last month, or the previous year, but it may be easy to understand because the final fuel consumption is an average fuel economy that reflects the value from the present to a predetermined period, especially when the final period is current. In addition, it is easy for the user to understand when the vehicle information display system is attached to the vehicle as in the present embodiment or when an instruction from a user such as a driver is given.

  In the present embodiment, the deviation of the latest instantaneous fuel consumption from the average fuel consumption is, for example, a value obtained by subtracting the average fuel consumption from the latest instantaneous fuel consumption. However, the present invention is not limited to this, and may be obtained by various methods.

  In the present embodiment, the predetermined filling mode from the reference position is a solid single-color coating. However, the present invention is not limited to this, and it may be a predetermined pattern such as hatching. In particular, the predetermined filling mode may be a predetermined continuous pattern or a repeating pattern. Further, as in the present embodiment, the larger the deviation is, the better it is to display the color from a reference position to a position farther away. In the present embodiment, one color fill display is performed, but a plurality of colors may be used for fill display.

  In the first vehicle information display screen of FIG. 5, when the range of the fill display changes with a change in deviation, the fill display or the fill display is canceled gradually from the position before the change to the position after the change. You may make it perform a complementary display. For example, the instantaneous fuel consumption is acquired every second, but the complementary display may be performed every 1/20 second. In this complementary display, the fill display from the reference position when the deviation is changed in a larger direction may be performed earlier than the fill release display when the change is changed in a smaller direction. In other words, the complementary display in the direction of increasing deviation is performed at twice the speed of the complementary display in the direction of decreasing deviation, and the complementary display (release display) in the direction of decreasing deviation is in the direction of increasing change. It is better to perform at half the speed compared to the complementary display.

  Further, in the present embodiment, the deviation calculation interval is set to 1 second, which is the instantaneous fuel consumption acquisition interval, but may be the same as the refresh rate of the display screen. In this way, it is possible to display smoothly. Preferably, the update is performed several times to several tens of times per second.

In the present embodiment, since the display unit 5 that displays the deviation is a color dot matrix liquid crystal display, the content of the fill display can be made flexible. In the present embodiment, the display unit 5 is a liquid crystal display having a backlight. What is displayed may be used. In this way, the deviation can be easily visually recognized even in a dark environment such as at night.
Further, the fill width of the fill display may be one dot as in the example of FIG. 7, or may be a plurality of dots as in the example of FIG.

  When the instantaneous fuel consumption cannot be acquired from the vehicle side, it is preferable that the fill display based on the instantaneous fuel consumption is not performed. For example, the instantaneous fuel consumption display area in FIG. 5 may not be displayed (blacked).

In addition, although the radar detector of this embodiment was set as the structure fixed on a dashboard, it is good also as a structure fixed with respect to a windshield. As a structure to fix, you may make it stick with an adhesive agent, a double-sided tape etc., for example, and you may make it adsorb | suck and fix with a suction cup etc.
The first vehicle information display screen may further include the following configuration.

  A configuration in which the position of the end of the solid display of the block from the reference position corresponding to the maximum value of a plurality of deviations for a predetermined time (for example, 3 minutes) longer than the latest instantaneous fuel consumption acquisition interval is displayed. Good. In this way, for example, the maximum value of the instantaneous fuel consumption at a plurality of different times acquired within a continuous predetermined time can be grasped in relation to the reference position, and the maximum value and the current instantaneous fuel consumption can be determined. The size relationship can be grasped at a glance. It is also possible to easily determine whether or not the current instantaneous fuel consumption exceeds the maximum deviation within the predetermined time. The display of the position of the end of the fill display may be performed, for example, by filling a line or a block of a predetermined color (fifth color (for example, shiba)).

On the other hand, according to the second vehicle information display function of the present embodiment, the history of paint display is displayed for at least the past three minutes. Therefore, it is possible to confirm the transition of the deviation for the past three minutes and to confirm the history of the past deviation and the current deviation in comparison. The past display of the past is displayed so that the fill display corresponding to the latest instantaneous fuel consumption is performed in either the upper or lower direction with the position of the right end (first dot) of the reference line as the reference position. It is configured to perform scroll display. In other words, the right end of the graph is fixed as the position of the fill display corresponding to the latest instantaneous fuel consumption, and the deviation of the latest instantaneous fuel consumption is displayed in the vertical direction from the right end. I have to. In this way, it is possible to easily check the deviation from the present to the past for a certain period of time, and to grasp the latest instantaneous fuel consumption at a glance.
Furthermore, the second vehicle information display function may have the following configuration.

  -It is good to make it the structure which highlights the peak point of the fill display in the display of a history. For example, it is preferable to perform display with increased brightness of the peak value dots. In this way, it is possible to easily check the maximum deviation value in the history display, and easily check the level of the latest instantaneous fuel consumption deviation from this peak point. be able to. Also, a configuration for displaying the position of the end of the fill display from the reference position corresponding to the maximum value of a plurality of deviations during the past three minutes that is a predetermined time longer than 1 second, which is the acquisition interval of instantaneous fuel consumption, and Good. For example, a parallel line having the same length as the reference line is drawn in the left-right direction so as to pass through the dots at the upper and lower ends of the portion displaying the longest line in the up-down direction for the past three minutes. In this way, for example, the maximum value of the instantaneous fuel consumption at a plurality of different times acquired within a continuous predetermined time can be grasped in relation to the reference position, and the maximum value and the latest instantaneous fuel consumption can be determined. The size relationship can be grasped at a glance. It is also possible to easily determine whether or not the latest instantaneous fuel consumption exceeds the maximum deviation within the predetermined time.

  It is preferable that the display of the ratio regarding the plus direction filled area and the minus direction filled area in the history display range is performed together with the history display. For example, the ratio may be numerically displayed in the upper area of the graph. In this way, it is possible to easily grasp whether the latest instantaneous fuel consumption is good or bad with respect to the average fuel consumption within the history range. In this case, for example, the range of information used for calculating the average fuel consumption may be a range that is displayed as a history, or may be a range that exceeds this range. It is better to be in the range. The ratio of the positive fill area and the negative fill area may be, for example, the ratio of the positive fill area itself and the negative fill area itself, or the latest obtained to perform this fill. It is good also as ratio of the integral value of the magnitude | size of each log | history of the plus direction and the minus direction of the deviation from the average fuel consumption of instantaneous fuel consumption. As described above, the ratio may be displayed numerically as described above, and a line or the like may be drawn on the history according to the ratio.
