Description

  The present invention relates to an electronic system and a program that display a variation display section prepared according to driving information of a vehicle on a screen.

  Various meters are arranged in front of the driver's seat in order to serve as an index for the driver as a user to judge the state of the vehicle when driving the vehicle. Examples thereof include a speed meter, a rotation speed meter, a water temperature meter, and a fuel meter. Patent Document 1 is given as an example for allowing the driver to visually recognize various meters.

JP 2003-229776 A

However, there has been a demand for users to obtain information other than information that can be obtained from a meter that is generally provided in the vehicle, and use it as an index for judging the state of the vehicle in more detail. In particular, a general vehicle that is not a race specification is often equipped with only the necessary minimum meter as described above, and other driving information of the vehicle cannot be easily obtained.
On the other hand, a vehicle information display device such as a navigation device or a microwave detector (radar detector) may be mounted on the vehicle, and the vehicle driving information is displayed on a standby screen of these vehicle information display devices. Is assumed to be displayed. However, there are various vehicle driving information, and information requested by the user is not always constant. In addition, the user often wants to obtain not only a single piece of driving information but also a combination of several pieces of driving information. This is because obtaining more vehicle information provides a more accurate index for determining the driving state of the vehicle. However, the required driving information varies depending on the driving situation and the user level, and the driving state displayed on the screen must be easy to see.
Therefore, there has been a demand for a device that can arbitrarily select a plurality of driving information of a vehicle and can simultaneously provide the plurality of driving information to a user on a screen.
The present invention has been made to solve the above problems, and an object thereof is to provide an electronic system and program capable of arbitrarily selecting driving information of a plurality of vehicles and simultaneously viewing the selected driving information. There is.

In order to achieve the above object, in the first means, a plurality of variable displays to be displayed are displayed from a plurality of variable display units prepared in accordance with vehicle driving information based on a selective input operation by a user. The gist of the present invention is to include control means for selecting and displaying a part on the screen and displaying the plurality of fluctuation display parts displayed on the screen according to the change of the driving information.
With such a configuration, the control means displays on the screen a plurality of variation display units selected by the user from a plurality of variation display units prepared according to the driving information of the vehicle, A variable display is made according to the change. As a result, the user can arbitrarily display a plurality of fluctuation display sections on the screen and visually recognize the driving information of a plurality of desired vehicles, so that the user can more accurately determine the driving state of the vehicle. Will be obtained.

Here, the “variation display unit” is an image that fluctuates on the screen corresponding to various driving information of the vehicle, and more specifically, as will be described later, the meter object and the vehicle displayed as an image on the screen. It is considered as a superordinate concept such as a graph that shows driving information, a model that shows a specific part of a vehicle, and a variable display according to a change in the driving information. These fluctuation display sections will fluctuate in accordance with changes in the driving information of the respective vehicles.
Here, as the “electronic system”, for example, an electronic device having a casing such as a radar detection device as a vehicle information display device, a navigation device, or a drive recorder can be cited. In addition, the screen on which the variable display unit is displayed may be integrated with the control unit on the electronic system side, and exists as a separate screen that is separated and output data from the control unit wirelessly or by wire. It doesn't matter. In addition, the electronic system is not necessarily installed in the vehicle. For example, it is also possible to perform control so that a casing including a control unit is installed outside the vehicle, vehicle information is received wirelessly, and the current fuel consumption state is variably displayed on a screen arranged in the vehicle. Further, all of the control means do not have to be in the vehicle, and some of them may exist outside the vehicle (for example, a server).
In addition, “selective input operation by the user” is input by an input button for selection or an operation unit for key operation, or when the screen has a touch panel function, the screen is touched to display a GUI screen. Select the input mode from the input, or input from an external personal computer via a server or the like arranged outside the vehicle, input selection data from the external personal computer to the storage medium (for example, SD card), control means It can be assumed that data is transferred and input by attaching a storage medium in a housing including
The “screen” can be assumed to be a screen of, for example, an organic EL display, a liquid crystal display, or a CRT display, which is a display means having a display unit on which moving images and still images are displayed. In particular, a dot matrix display may be used.

The gist of the second means is that, in addition to the first means, the control means is provided in the vehicle, and the screen is arranged at a position visible to the driver in the vehicle.
Although the screen (display means having a screen) could be configured separately, it is advantageous in handling that it is mounted on the vehicle together with the control means at least in the main body of the electronic system. When mounted on the vehicle here, the screen is disposed in the casing of the electronic system main body in which the control means is disposed, and the control means is arranged in the vehicle separately from the electronic system main body. The term “includes” includes both cases where the connection is made by wireless or wired such as a cable.

The gist of the third means is that, in addition to the first or second means, the driving information is information obtained from information output means provided in the vehicle itself.
That is, the driving information that can be obtained from the vehicle by some acquisition means. Such information can be generally obtained from a K line or a CAN (Controller Area Network) in which terminals are provided on a vehicle diagnosis connector for ODB-II (On-Board Diagnostic System Stage 2), which is required to be installed in the vehicle. However, if there is means for obtaining data from other than the vehicle diagnostic connector in the vehicle, it is also free to use it.
Driving information that can be acquired from the vehicle includes, for example, vehicle speed, injection injection time, ignition timing, intake air amount, intake air temperature, water temperature, air fuel efficiency correction coefficient, battery voltage, remaining fuel amount, flow rate pulse from a flow meter, Examples include the amount of oil supply, engine speed, throttle opening (accelerator opening), throttle sensor voltage, airflow voltage, boost pressure, and the like.

In the fourth means, in addition to any one of the first to third means, the driving information is information obtained from information obtaining means disposed in the vehicle separately from the vehicle. And
Information obtained from information acquisition means arranged in the vehicle separately from such a vehicle is information that cannot be obtained from the vehicle, and is important as an information source.
Examples of such information acquisition means include current position acquisition means, current time acquisition means, speed acquisition means, acceleration acquisition means, and the like. More specific means of the current position acquisition means, current time acquisition means, and speed acquisition means include, for example, a GPS receiver provided in a radar detection device, a navigation device, a drive recorder, or the like. Further, as a more specific means of the acceleration acquisition means, for example, an acceleration sensor (two-axis type or three-axis type) provided together with a radar detection device, a navigation device, a drive recorder, or the like can be cited.

In the fifth means, in addition to any one of the first to fourth means, the fluctuation display section includes a graphical display section and a numerical display section for the driving information, and the control means is provided in the numerical display section. The gist is to display numerical values in a manner in which display elements in the graphic display unit are associated with each other.
By adopting such a configuration, numerical values are displayed in a manner associated with fluctuations in the graphic display unit, so that the fluctuations in the graphic display unit can be visually recognized and at the same time an accurate numerical value corresponding to the fluctuations Information can be obtained.
Here, “displaying numerical values in a manner associated with display elements in the graphic display unit” means, for example, a case where numerical values are written at a position adjacent to a meter object described later, or a current operating state in a graph described later In this case, the numerical value corresponding to is displayed in relation to the plot position.
The sixth means is characterized in that, in addition to the fifth means, the scale of the numerical value display unit is changed in accordance with the change in the driving information of the vehicle.
For example, the speed, engine load, and engine speed are not so high in the early stage of vehicle travel. On the other hand, both become larger after a while from running. Therefore, it is possible to display more optimally and without waste by initially displaying the image on a small scale and setting the scale to a large scale according to traveling. In particular, since the screen of a vehicle-mounted device is small, it is preferable that the scale can be changed in this way. The same applies to the case where the vehicle speed decreases from the normal traveling state in the stop direction.

In the seventh means, in addition to any one of the first to sixth means, the control means displays information irrelevant to the information content displayed on the variable display section on the screen simultaneously with the variable display section. Is the gist.
By adopting such a configuration, for example, a predetermined event has occurred while displaying a plurality of fluctuation display parts on the screen, without relevance to a fluctuation element that fluctuates the fluctuation display part currently displayed on the screen. Other information about the event can be displayed on the screen. As a result, other information that suddenly issues a warning to the user is displayed as temporary information while the current fluctuation display section is continuously displayed on the screen without erasing the fluctuation display section from the screen. Can be made.

In the eighth means, in addition to any one of the first to seventh means, a meter object is provided as the fluctuation display unit, and the control means displaces the pointer object in the meter object according to the change of the driving information. The gist is to display the information in a variable manner.
That is, it is changed by an operation in which the needle is actually rotated according to the change of the driving information. Since the user visually recognizes the daily driving information in the meter format, the driving information can be easily grasped if the variable display is often found in the meter format. Examples of the driving information suitable for the variable display on the pointer object include fuel efficiency information, cooling water temperature information, engine speed information, vehicle speed information, engine load factor information, and the like.

In the ninth means, in addition to any one of the first to eighth means, a meter object is provided as the fluctuation display section, and the control means changes with respect to the background in accordance with the change of the driving information in the meter object. The gist is to display a variable display in which the area occupied by the index object corresponding to the amount changes.
That is, the area displayed in the meter object is changed according to the change of the driving information. Similarly to the above, since the user visually recognizes the daily driving information in the meter format, it is easy to grasp the driving information if the variable display is often found in such a meter format. As the direction of variation of the area, the rotation direction and the vertical and horizontal directions can be assumed. The change in area includes not only the change of the boundary line position of areas divided by different colors and brightness on the screen, but also the case where the area is expressed by increase / decrease of lines / patterns occupying one area.
Examples of the driving information suitable for the change display due to the change in the area occupied by the index object include throttle opening information and engine load factor information.

In the tenth means, in addition to any of the eighth and ninth means, the outer shapes of the meter objects are the same or similar to each other, and the control means displays a plurality of the change display sections on the screen. The gist is to display the same size when it is done.
In such a configuration, when a plurality of meter objects are displayed on the screen, even if different driving information is displayed, they are displayed in the same size. Since the screen size does not change, if the number of meter objects displayed on the screen increases, the size of the meter object is gradually reduced to fit on one screen. Although it is preferable from the viewpoint of visibility to be arranged in series in the horizontal direction, when the number of displayed meter objects is increased, it may be arranged in two or more rows in order to ensure as large a size as possible.

In the eleventh means, in addition to any one of the first to seventh means, a specific vehicle that displays the driving information as a fluctuation display unit in accordance with a change in the driving information by schematically modeling a specific part of the vehicle. The gist is to provide a part object.
Such a specific vehicle part object has a very different appearance from a fluctuation display unit such as a meter that is normally mounted on a car, and has an animation-like fluctuation movement, so it is highly resistant to the user's vision. It is excellent as a variable display part.
As a schematic representation of a specific part of the vehicle, a part that moves as the vehicle travels is preferable, and a part that changes in movement depending on driving conditions is preferable.
For example, a partial cross-sectional shape around the engine (internal structure and surroundings), tire rotation operation, and the like, which are the most important as vehicle information, are given as examples.
The change display in this case is, for example, a change in the structure around the engine (a change in the speed of the reciprocating motion of the piston, a change in the rotational speed of the crankshaft, a speed change in the reciprocating motion of the intake / exhaust valve, a speed change of the cam or camshaft, etc.) ) Or a change in shape such as a change in the rotational speed of the tire, or may be expressed by a change in the color of the members constituting these objects. Color change is a concept that includes not only saturation change but also lightness change.

In the twelfth means, in addition to any one of the first to eleventh means, the gist is that the control means causes the fluctuation display section to perform fluctuation display based on a plurality of the driving information.
In such a configuration, a specific vehicle part object can be mixed with a part that performs variable display corresponding to a number of driving information, and a plurality of driving information fluctuations can be given to the user at the same time as a plurality of driving information. In order to transmit driving information to the user, it is not necessary to prepare a number of variable display units as separate bodies.
More specifically, for example, a trip meter-like display as a meter object, that is, a variable display of the corresponding driving information up to the present after setting, such as the distance traveled to the present after setting and the average fuel consumption or average speed between them It is possible to envisage such a variable display unit.
In the case of the specific vehicle part object, for example, the change display based on the driving information in the change in the internal structure of the engine is realized by changing the shape of the piston object or the like, and at the same time, the change based on the other driving information. It can be assumed that the display is realized by a color change of the piston object or the like.

In the thirteenth means, in addition to any one of the first to seventh means, the fluctuation display unit uses the two types of driving information as axes in the vertical and horizontal directions of the graph, respectively, and the two types of the driving acquired by the vehicle. The gist is that the graph object displays a position corresponding to the numerical value of the information on the graph.
That is, a graph having a vertical axis and a horizontal axis for any two types of driving information is displayed as a graph object on the screen as a kind of variation display unit. This is because the state of the vehicle can be determined more precisely by displaying the correlation between the two types of driving information in real time. In addition, although such a graphed information display mode is useful as an index for judging the driving state of the vehicle, it is generally not displayed on the vehicle. It is beneficial for.
As the display mode on the graph, the intersection of the numerical values on the current vertical and horizontal axes is always displayed on the graph, or the vertical and horizontal line segments are displayed so that the intersection position is the point indicating the current state. Good. In addition, only the current state may be displayed at all times, or past history may be displayed at the same time.
The two types of operation information are, for example, information that has a correlation such that the vertical axis is the speed, the horizontal axis is the engine speed, the vertical axis is the fuel flow rate, and the horizontal axis is the operation time. It is not limited.

In the fourteenth means, in addition to the thirteenth means, the control means displays a numerical value corresponding to the driving information in association with the current position on the graph.
With such a configuration, it is possible to obtain numerical information on what value the current (current) position on the graph is exactly.
Here, “associate with the position on the current graph” means that when the numerical value is displayed, the numerical value is displayed in relation to the displayed position on the graph even if it is not necessarily near the position on the graph. It means to be enough.
In the fifteenth means, in addition to the fourteenth means, the position on the graph is indicated by the intersection of a first straight line parallel to the vertical axis and a second straight line parallel to the horizontal axis on the graph. The gist of the control means is that the numerical values of the axes intersecting the straight lines are written on the straight lines as numerical values corresponding to the driving information.
The fifteenth means is a specific example of the fourteenth means, and regarding “associating with the position on the graph”, the intersection of the first straight line and the second straight line is set as the position on the graph in this way. In this case, the margin is written on each straight line, not in the vicinity of the intersection. Also, the visibility near the intersection is improved. In this case, the intersection of the first straight line and the second straight line is preferably present in a fixed region of the graph as much as possible. For this reason, the scale of the vertical and horizontal axes is appropriately changed or the position of the scale displayed on the axis is moved. Is preferable.

In the sixteenth means, in addition to any one of the thirteenth to fifteenth means, the gist is that the control means displays a history of positions on the graph obtained at a predetermined timing.
This means that not only the position on the current graph but also the history of positions on the past graph is displayed. This is because such a configuration is an important index for determining what kind of driving situation it is.
Since the history is acquired at a predetermined timing, it is displayed as scattered points. However, it may be displayed as a scattered pattern as it is, or may be displayed as another expression, for example, a line graph or a bar graph.

The gist of the seventeenth means is that, in addition to the sixteenth means, the display number of the history of the position displayed on the graph is limited, and the control means deletes the oldest history.
If the past history position gradually increases on the graph, the screen becomes rather difficult to see. Therefore, by deleting the oldest history, the number of history displayed on the screen is limited to make it easier to see. The maximum number of histories to be displayed on the screen is not constant depending on the size of the screen to be displayed, that is, the number of pixels, but about 500 to 1000 points is appropriate for a small screen (2 to 5 inch screen). .
The gist of the eighteenth means is that, in addition to the sixteenth or seventeenth means, the display time of the history of the position information displayed on the graph is limited.
This is to prevent the past history positions from gradually increasing on the graph as in the seventeenth means, and becoming difficult to see. For example, only the history acquired in the past 15 minutes from the present time is always displayed, and the history position acquired before 15 minutes is deleted.
In the nineteenth means, in addition to the seventeenth or eighteenth means, the update timing of the display of the position information on the graph is 1 second or less.
This is because if the update timing is too long, the data becomes rough information, which may be meaningless. On the other hand, even if it is too short, for example, when the history is left in time as in the fourteenth means, it will be very large even if it is a short time. Moreover, even if it is intended to leave a history of a certain amount of time, there is a possibility that the history displayed on the screen is so much that it is difficult to understand as driving information. Therefore, although the update timing is 1 second or less, 5 ms (millisec) or more is preferable.

In the twentieth means, in addition to any one of the first to nineteenth means, the driving information includes fuel consumption information, cooling water temperature information, fuel flow rate information, engine speed information, vehicle speed information, engine load factor information, throttle The gist thereof is any one of the opening degree information, the vehicle position information, the current time information, and the acceleration information. Fuel consumption is the fuel consumption rate.
These are examples of vehicle driving information. The fuel efficiency information includes instantaneous fuel efficiency, current fuel efficiency, all road average fuel efficiency, general road average fuel efficiency, and expressway average fuel efficiency.
The gist of the twenty-first means is a program for causing a computer to realize the function of the control means in the electronic system according to any one of the first to twentieth means.

  According to the present invention, since a user can obtain driving information of a plurality of vehicles simultaneously and arbitrarily from other than the meter originally mounted on the vehicle, a precise driving state of the vehicle according to the user's desire is determined. An indicator will be obtained.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments embodying the present invention will be described below with reference to the drawings.
FIG. 1 is an external perspective view of a radar detector 10 as an electronic system (electronic device). The radar detection device 10 has a mechanism housed in a substantially rectangular parallelepiped casing 11 serving as a main body, and is fixed on a dashboard, for example, via a mounting bracket 12 in the vehicle.
A display unit 14 is exposed in a frame-shaped front frame 13 disposed on the front surface of the housing 11 (the surface facing the driver). In the present embodiment, the display unit 14 is composed of a small 4.3 inch liquid crystal display. The display unit 14 also serves as a touch panel as input means. A slot 15 for inserting an SD card as a storage medium is formed on the side surface of the housing 11. A main cable 17 extends from the rear surface of the housing 11 (the surface facing the front window). As shown in FIG. 2, a female connector 18 is fixed to the tip of the main cable 17. A power switch (not shown) is formed on the rear surface of the housing 11.
As shown in FIG. 2, the radar detection device 10 is connected to a vehicle diagnostic connector 22 having a front shape as shown in FIG. The vehicle diagnosis connector 22 as information output means is disposed at a predetermined position (not constant depending on the vehicle type) that does not interfere with driving in the vehicle. The connection adapter 21 has a male connector 24 and a connection connector 25 at both ends of the connection cable 23. A female connector 18 and a male connector 24 at the tip of the main cable 17 extending from the radar detection device 10 are connected, and a connection connector 25 is connected to a vehicle diagnosis connector 22 installed on the vehicle side. In the present embodiment, the radar detection device 10 obtains power from the IGN signal terminal in the vehicle diagnosis connector 22, but a DC power jack is provided to obtain power from a cigar socket, for example. It is also possible.

Next, the electrical configuration inside the casing 11 of the radar detection device 10 will be described with reference to the block diagram of FIG. In addition, about the structure which is not directly related to this invention, it abbreviate | omits.
A position detector 31, a microwave detector 32, a wireless receiver 33, a memory card reader 34, an acceleration sensor 35, a database 36, and the display unit 14 are connected to the controller MC as a control means.
The controller MC includes a known CPU, a memory such as a ROM and a RAM, a timer, and the like. The map data is called into the ROM in the controller MC and displayed on the display unit 14 in association with the obtained target data and detection data of a speed measuring device (mobile radar or the like (hereinafter simply referred to as “radar”)). Received by the radio receiver 33, a GPS information processing program for processing the GPS information received by the GPS receiver 37, a microwave determination program for determining the microwave received by the microwave detector 32, and a radio receiver 33 A radio wave determination program for determining radio waves, a fuel efficiency calculation program for arbitrarily acquiring various vehicle information output from the vehicle diagnosis connector 22, and performing calculations such as fuel flow rate and various fuel efficiency based on the information, a user A predetermined standby image is displayed on the display unit 14 by the operation of Various programs such as a standby screen display program to be displayed, a variable display program for variably displaying a predetermined object in a predetermined standby image displayed on the display unit 14, and an OS (Operation System) are stored in the RAM. Stores various vehicle information acquired from the vehicle diagnosis connector 22, calculated values calculated by the fuel efficiency calculation program, and position information detected by the position detector 31.
The controller MC converts the vehicle information output to the K line or CAN of the vehicle diagnosis connector 22 on the vehicle side via the interface 28 into a processable communication protocol, for example, a UART signal.

The position detector 31 as current position acquisition means, speed acquisition means, and current time acquisition means includes a GPS receiver 37 that acquires GPS information as the core of the configuration, and is determined by the GPS receiver 37 based on instructions from the controller MC. Detects the position of the vehicle at the current time. The detected position information is the speed, latitude, longitude, and altitude of the vehicle. The microwave detector 32 detects a predetermined microwave from the received microwave. The radio receiver 33 detects a predetermined radio wave from the received radio wave. The memory card reader 34 reads data of an SD card as a memory card inserted into the slot 15 to be inserted or updates data of the SD card.
The acceleration sensor 35 as an acceleration acquisition means is a three-axis type sensor that detects acceleration and inclination in the directions of the three axes (X, Y, Z), and always outputs a detection value to the controller MC.
The database 36 is a nonvolatile memory (for example, EEPROM) in the controller MC or externally attached to the controller MC. In the present embodiment, the database 36 stores object data to be displayed on the display unit 14 in a standby state, master image data, various font data to be displayed on the display unit 14, and the like. These data may be stored in the ROM.
Further, the controller MC detects a contact state with the display unit 14 at a timing of several milliseconds, and performs processing according to a command by a GUI input.

In such an electrical configuration, the controller MC outputs a command to the K line or CAN terminal of the vehicle diagnosis connector 22 using a predetermined protocol, and acquires predetermined vehicle information via the K line or CAN. The driving information that can be acquired includes vehicle speed (vehicle speed), injection injection time, ignition timing, intake air amount, intake air temperature, water temperature, air fuel efficiency correction coefficient, battery voltage, remaining fuel amount, flow rate pulse from flow meter, fueling The amount, engine speed, throttle opening (accelerator opening), throttle sensor voltage, airflow voltage, boost pressure and the like can be mentioned. The fuel flow rate, instantaneous fuel consumption, fuel consumption per driving (current fuel consumption), past driving fuel consumption (all road average fuel consumption) expressway, with these information as is or information obtained from the vehicle diagnosis connector 22 as primary information If calculation is required for average fuel efficiency, general road average fuel efficiency, mileage, engine load factor, etc., they are calculated and acquired as secondary information. In addition, although the vehicle speed can be acquired by the GPS receiver 37 as described above, priority is given to the vehicle speed acquired from the vehicle diagnosis connector 22 in the present embodiment.
There are several means for obtaining the fuel flow rate (calculation method). First, when a fuel consumption value is periodically output from the vehicle side, the value is used as it is. On the other hand, when the value of the regular fuel consumption cannot be obtained, it can be calculated by a known method based on either the intake air amount or the injection injection time at a constant sampling time. In this embodiment, the injection injection time is used. Although the sampling time is arbitrary, it is 1 second here.
The injection injection time (valve opening time) can be calculated by giving a predetermined correction value to the output of the air flow meter (the air flow rate of the intake duct) and the engine speed, and performing various predetermined corrections. This corrected fuel flow rate is taken as fuel consumption. The fuel flow rate for 1 second corresponding to the sampling time is taken as the acquired fuel flow rate. By dividing the integrated value of the obtained fuel flow rate at a predetermined time by that time, the average fuel flow rate within that time can be calculated.
First, when the instantaneous fuel consumption is periodically output from the vehicle side, the value is used as it is. If it cannot be obtained, the travel distance is calculated from the speed and travel time of the vehicle at a fixed sampling time, divided by the fuel flow rate, and calculated by giving a correction value. The vehicle speed is obtained from the vehicle diagnosis connector 22 described above, and the time is obtained from a known timer attached to the controller MC. Alternatively, similar to the above, it may be calculated by giving a predetermined correction value to the output of the air flow meter and the engine speed and performing various predetermined corrections.
The average fuel consumption is calculated from the accumulated instantaneous fuel consumption and travel time. The controller MC calculates the average fuel consumption in the time from the start of the engine to the present time.
The fuel consumption per operation is calculated by integrating the acquired fuel flow rate from the start to the stop of the engine and calculating and dividing the travel distance between them. The accumulated fuel consumption of past driving is calculated by adding up past fuel flow rates and calculating and dividing the total travel distance.
Expressway average fuel efficiency is based on the expressway information (tollgate location and rampway). The road is recognized as an expressway and the fuel flow rate of the acquired expressway is added up to calculate the total travel distance of the expressway. It is calculated by dividing the integrated fuel flow rate.
The average road average fuel consumption is calculated by integrating the fuel flow rate other than the expressway, calculating the total travel distance other than the expressway, and dividing the accumulated fuel flow rate.
The engine load factor is calculated as the ratio of the current intake air amount to the maximum intake air amount.

Next, various objects that are displayed and controlled by the controller MC as a part of the standby screen of the display unit 14 will be described with reference to FIGS. FIGS. 5 to 14 are objects that display variation based on the driving information of the vehicle acquired from the vehicle diagnosis connector 22 that is an information output means.
The controller MC calls various object data stored in the ROM, and variably displays it in accordance with changes in the driving information in combination with the master image data of the standby image that has been called. Generally, the liquid crystal display of the display unit 14 displays characters and objects having saturation and brightness on a black background. In the present embodiment, since there are restrictions on the representation in the drawing, some fine points are omitted, the background is shown in white, and characters and objects are expressed in black, hatch lines, and the like. The actual display modes of various objects on the display unit 14 are illustrated in FIGS. 9 and 18 to 21.
Other than the object data specialized for the present invention (clock object for displaying time, level object for displaying the inclination of the vehicle, acceleration display object for displaying the direction and magnitude of acceleration applied to the vehicle, GPS positioning The illustration of the master image of the standby image combined with the earth object indicating the receiving satellite position is omitted.

As shown in FIG. 5 (a), as a plurality of driving information, five types of fuel consumption (instantaneous fuel consumption, current fuel consumption, all road average fuel consumption, expressway average fuel consumption, general road average fuel consumption) and changes in the coolant temperature A first meter object 40 is provided for displaying fluctuation. That is, the 1st meter object 40 is an object which can display several driving information by one. The display image actually developed on the display unit 14 of the first meter object 40 is shown in FIG. 9A (however, the saturation does not appear in the monochrome display. The same applies hereinafter).
The first meter object 40 has a circular surrounding ring 41 as an outer shell. The surrounding ring 41 is decorated with a metal reflecting portion as if it is made of metal as an actual image. On the surrounding ring 41, screw objects 41a are arranged at positions shifted by 30 degrees from the 12 o'clock position (12 in total). The circular inner region surrounded by the surrounding ring 41 is divided into two vertically at the center position. The upper area 40a is provided with a fan-shaped display portion 42 having a fan-shaped window-hole-like image. A pointer object 43 extending outward from the center of the first meter object 40 in the fan-shaped display unit 42 is displayed. The controller MC causes the pointer object 43 to display a variable display that swings in the left-right direction with the center as the base position in the fan-shaped display unit 42 in accordance with the value of the driving information. As the position suggested by the pointer object 43, the value on the left side of the figure is lower (L) and the value on the right side is higher (H). A block object 44 serving as an index indicating the position of the simple pointer object 43 is displayed at the outer peripheral position of the fan-shaped display unit 42. Since the first meter object 40 is common to six types of different driving information of five types of fuel consumption and cooling water temperature, the numerical value that the scale means depends on the driving information. The controller MC causes the lower value 40b of the first meter object 40 to display the acquired value in the currently selected driving information together with its unit. For example, in FIG. 5, the instantaneous fuel consumption is displayed as “60 km / l”, and it can be accurately understood as a numerical value that the fuel consumption at this moment is 60 km per liter.

As shown in FIG. 5B, the second meter object 45 for displaying the fluctuation according to the change in the fuel flow rate as the operation information has the same outer shape of the surrounding ring 41 as the first meter object 40. However, the inner region is divided into two parts vertically. The display image actually developed on the display unit 14 of the second meter object 45 is FIG. 9B.
The controller MC causes the upper region 45a to display a variation region 46 in which the interface moves up and down as if the water surface was moved up and down in the upper region 45a according to the change in the fuel flow rate. As the fuel flow rate increases, the interface moves in the upward direction. The controller MC displays the acquired value of the current fuel flow rate together with the unit in the lower area 45b of the second meter object 45. Since the fuel flow rate is an amount (milliliter) flowing in one minute, ml / m is displayed as a unit.

  As shown in FIG. 5C, the third meter object 47 for displaying the fluctuation according to the change in the engine speed as the operation information has the same outer shape of the surrounding ring 41 as the first meter object 40. Have. The display image actually developed on the display unit 14 of the third meter object 47 is shown in FIG. In the circular area 47a of the third meter object 47, the pointer object 48 is displayed so as to extend outward from the center of the circular area 47a. The pointer object 48 has a center position as a rotation base, and the controller MC causes the pointer object 48 to display a change display that rotates in the left-right direction with the center as a base position in response to a change in engine speed. Turning to the right is an increasing direction. As the operation information, x1000 rpm which is a unit of the engine speed is displayed at a position slightly lower than the center in the circular area 47a. A scale is displayed at the outer peripheral position adjacent to the surrounding ring 41 in the circular region 47a. One scale indicates 0.2, and numerical values corresponding to integer positions such as 0, 1, 2, 3,... Are arranged clockwise. The 0 position on the scale is arranged corresponding to the position of the screw object 41a at the 7 o'clock position, and the maximum scale 10 is arranged on the screw object 41a at the 5 o'clock position. The scale of the integer position is long and extends to the surrounding ring 41, and at the same time, the integer position corresponds to the position of the screw object 41a. In other words, the decorative screw object 41a also functions to complement the scale, making it easy to determine the position of the pointer object 48 in the small meter object. The reason why the scale does not start from the 6 o'clock position is to prevent the positions of the minimum value and the maximum value from overlapping.

As shown in FIG. 5 (d), the fourth meter object 49 for displaying the fluctuation according to the change in the vehicle speed as the driving information has substantially the same shape as the third meter object 47. The difference in shape from the third meter object 47 is only the unit and interval of the scale and the position of the screw object 41a.
The scale is engraved from 0 to 240 so that one scale is 5 km / h. A numerical value corresponding to every 20 km / h is arranged clockwise. The number of screw objects 41a in the fourth meter object 49 is 14 in total, and is arranged at a position shifted by about 25.7 degrees from the 12 o'clock position. The scale of the numerical position is long and extends to the surrounding ring 41. At the same time, the numerical position corresponds to the position of the screw object 41a. As a result, the position of the screw object 41a is made to correspond to the position where the scale of the vehicle speed prepared from 0 to 240 at a scale of 5 km / h is set every 20 km / h. The screw object 41a has a screw object 41a (corresponding to 0 m / h) adjacent to the left on the left at 6 o'clock in the figure and corresponds to a scale every 20 km / h clockwise, and on the right in the figure at the 6 o'clock position. The adjacent screw object 41a (corresponding to 240 km / h) is set as the corresponding end point. This makes it easy to determine the position of the pointer object 48 in the small meter object as described above.
A display image actually developed on the display unit 14 of the fourth meter object 49 is shown in FIG.

  As shown in FIG. 5E, the fifth meter object 51 for displaying the fluctuation according to the change of the engine load factor as the operation information has the same outer shape of the surrounding ring 41 as the first meter object 40. And the inner region is divided into two vertically. The display image actually developed on the display unit 14 of the fifth meter object 51 is shown in FIG. The upper area 51a is a fan-shaped display 52 having a fan-shaped window-like image, similar to the first meter object 40, and the controller MC is a small fan-shaped index object divided into small pieces along the fan-shaped circumferential direction. By varying 53 in accordance with the change in engine load factor, the variable display is made to change the area of different colors with respect to the background. The display is such that the index object 53 increases from right to left as the engine load factor increases. In the present embodiment, the indicator object 53 that appears in the region where the engine load factor is small and the indicator object 53 that appears in the region where the engine load factor is large have different colors (the same gradation in the illustration of FIG. 5E). But is actually different). For example, in a region where the engine load factor is small, the blue color signifies safety, and the longer wavelength is displayed gradually as the engine load factor increases. The color is displayed in red. In the lower area 51b of the fifth meter object 51, the acquired value of the current engine load factor is displayed together with the unit. Since the engine load factor is expressed as a percentage,% is displayed as a unit.

  As shown in FIG. 5 (f), the sixth meter object 55 for displaying the fluctuation according to the change in the throttle opening as the operation information has the same outer shape of the surrounding ring 41 as the first meter object 40. And the inner circular region is divided into two vertically. The display image actually developed on the display unit 14 of the sixth meter object 55 is shown in FIG. The upper area 55a is a fan-shaped display part 56 having a fan-shaped window-like image like the first meter object 40, and the controller MC occupies the fan-shaped display part 56 of the fan-shaped object 57 along the fan-shaped circumferential direction. By increasing or decreasing the area according to the change in the throttle opening, an image is displayed so as to change the area having a different color with respect to the background. The display is such that the area of the fan-shaped object 57 increases from right to left so that the fan opens as the throttle opening increases. The fan-shaped object 57 imagines the opening amount of the throttle valve. Here, the area occupied by the fan-shaped object 57 with respect to the background corresponds to the throttle opening, but conversely the throttle opening with the area occupied by the fan-shaped object 57 You may make it correspond. The controller MC displays the value acquired as the current throttle opening together with the unit in the lower area 55b of the sixth meter object 55. Since the throttle opening is expressed as a percentage,% is displayed as a unit.

As shown in FIG. 5 (g), the seventh meter object 58 for causing the variable display of numerical values for two pieces of information, ie, a change in a predetermined distance and a change in fuel consumption during the driving information, is a first meter object. The outer shape of the surrounding ring 41 is the same as that of 40, and the inner region is vertically divided into two. The seventh meter object 55 has a function as a so-called trip meter. A display image actually developed on the display unit 14 of the seventh meter object 58 is shown in FIG.
The controller MC displays the distance from the reset to the upper area 58a to the present. The lower area 58b displays the fuel consumption from the reset to the present. A reset button object 59 is displayed on the right side of the upper region 58a and the lower region 58b, and can be reset by a GUI operation on the display unit 14.

As shown in FIG. 6, in the graph object 61 in which the correlation between the vehicle speed and the engine speed is graphed as the driving information, the vertical axis is set as the vehicle speed and the horizontal axis is set as the engine speed. The display image actually developed on the display unit 14 of the graph object 61 is as shown in FIG. The controller MC acquires the vehicle speed and the engine speed at a predetermined timing (in this embodiment, every second), and plots the position on the graph object 61 as a light spot occupying a certain number of pixels. The plotted light spot indicating the correlation between the vehicle speed and the engine speed at a certain point remains as a history, and the driving information indicating the correlation between the vehicle speed and the engine speed is recorded in a dotted pattern on the graph object 61 with time. It will be done. The controller MC deletes the oldest data from the screen in order with the history (light spot) plotted on the graph object 61 reaching a predetermined maximum history number (500 in the present embodiment). This prevents the screen from becoming full of dots and meaningless driving information, and always keeps the vehicle speed and engine speed in the latest few minutes (500 pieces = 500 seconds, so about 8 minutes). The correlation of numbers will be provided to the user in an easy-to-understand manner as driving information.
Here, there is no indication of when the plotted position was plotted, it was simply expressed as a light spot on the graph, so what is the correlation between the current vehicle speed and engine speed? Is difficult to understand. Therefore, in order to clarify the correlation between the current vehicle speed and the engine rotational speed, the controller MC passes the current vehicle speed and the engine rotational speed on the graph object 61 in the graph object 61, respectively. Two current position indication lines 62a and 62b parallel to the axis are displayed. The position plotted at the intersection position P of these current position indication lines 62a and 62b displays the current vehicle speed and engine speed. At the same time, as shown in FIG. 6, the controller MC accurately moves the engine position and the engine speed so as to follow the movement of the current position indicating lines 62a and 62b to the end positions of the current position indicating lines 62a and 62b outside the graph object 61, respectively. Display numbers as numbers.

The unit of the vertical axis and the horizontal axis of the graph object 61 is km / h and rpm, respectively, but the scale is not constant, and these vary depending on the driving situation.
For example, if the current state is within a few seconds from the start, the vehicle speed and the rotational speed are still low. Therefore, in the initial state of the graph object 61 as shown in FIG. 7, the maximum value of the vehicle speed scale is 50 km / h, and the maximum value of the engine speed displayed in the display area is 2000 rpm. In other words, a very large value is not displayed as a scale.
However, as the vehicle speed increases and the engine speed increases, the controller MC increases the scale according to the acquired vehicle speed and engine speed (scale up).
The scale-up timing is based on a shift to a vehicle speed or engine speed in a band to which a vehicle speed or engine speed of a vehicle belongs. In other words, when the vehicle speed or engine speed exceeds a certain level, the maximum vehicle speed and engine speed in the band to which the vehicle speed or engine speed belongs are set as the maximum values displayed in the display area, and the scale on the graph is accordingly displayed. Change the meaning of the unit amount. For example, the maximum value displayed in the display area is 50 km / h when the vehicle speed is in the range of 0 to 49 km / h, but the vehicle is scaled up when the vehicle speed exceeds 50 km / h. As a screen displaying 100 km / h. In this case, one scale is 5 km / h in the initial state as shown in FIG. 7, but is scaled up to 20 km / h as shown in FIG.
The engine speed is 2000 rpm from 0 to 1999 rpm. Similarly, the controller MC scales up when it exceeds 2000 rpm, for example, a screen displaying 6000 rpm as the maximum value as shown in FIG. Conversely, the scale is reduced (scale down) when the vehicle speed is 50 km / h or less, or when the engine speed is 2000 rpm or less.

  The controller MC displays the maximum value on the screen at the time of scale-up based on the past vehicle speed and the maximum value of the engine speed of the vehicle. For example, assume that the vehicle has traveled at a maximum speed of 95 km / h in the past. The maximum value displayed in the display area is associated with the band to which a certain vehicle speed belongs. For example, if the maximum speed is 50 to 99 km / h, the maximum value is 100 km / h, and if the maximum speed is 100 to 149 km / h, the maximum value is 150 km / h. Alternatively, the maximum engine speed is 3000 rpm up to 2000-2999 rpm, and the maximum value is 4000 rpm up to 3000-3999 rpm. These operation histories are stored in the RAM of the controller MC, for example. Then, the controller MC sets the maximum value of the band to which the maximum speed and the maximum engine speed to the present belong to the maximum value displayed in the display area at the time of scale-up in the next display on the graph object 61. With such a display mode, it is possible to develop a history on the graph object 61 around the correlation between the vehicle speed that matches the driving tendency of the vehicle and the engine speed, and the vehicle speed that is less likely to be used. The area of the engine speed region can be reduced from the graph object 61.

  As shown in FIG. 8, an engine object 65 for displaying changes in both the engine speed and the engine load factor as driving information in a variable manner is a variable object that is expressed by partially sectioning the inside of the engine. . Content constituting the engine object 65 includes a cylinder block 66, a piston 67, an intake / exhaust valve 68, and an impeller 70 of a turbocharger 69. Here, the cylinder block 66 and the housing of the turbocharger 69 are shown in cross section. The controller MC executes an animation in which the piston 67 moves up and down at high speed and the impeller 70 rotates at high speed as the engine speed increases. Further, the controller MC controls the color of the entire piston 67 displayed on the screen so as to correspond to the change in the engine load factor. That is, as the engine load factor increases, the color of the piston 67 is darkened (changed to a more conspicuous color). In the present embodiment, when the engine load factor increases, the color is set to change to red, which is a dangerous color, such as metal color → light pink → pink → red. A display image actually developed on the display unit 14 of the engine object 67 is as shown in FIG.

As shown in FIG. 10, in this embodiment, a first table object 71 for displaying the current values of the engine load factor, the throttle opening, the fuel flow rate, and the instantaneous fuel consumption is prepared. The first table object 71 is used for displaying on the standby screen simultaneously with the engine object 65. This is because these items are information that is strongly related to the engine object 65 and is preferably displayed simultaneously with the engine object 65.
As shown in FIG. 11, the current fuel consumption, current average road fuel consumption, current fuel consumption, general road fuel consumption, fuel flow rate, highway fuel consumption, vehicle speed, engine speed, coolant temperature, engine load factor, throttle opening A second table object 72 that displays the numerical value of the driving information is prepared. These 11 types of driving information are used for displaying on the standby screen alone as important vehicle driving information acquired from the vehicle diagnosis connector 22. These eleven types of driving information are information that is variably displayed in the first to seventh meter objects 40, 45, 47, 49, 51, 55, and 58 described above.

Next, the configuration of the standby image for the standby screen prepared in the present embodiment will be described. In the present embodiment, the first to seventh meter objects 40, 45, 47, 49, 51, 55, 58, the graph object 61, the engine object 65, the first table object 71, and the second table object 72 are described. Four types of standby images to be displayed on the display unit 14 in combination with the above will be described.
12 to 15 are standby screens created by combining these objects with the standby image P1. 12 is combined with the second, fifth and sixth meter objects 45, 51 and 55, FIG. 13 is combined with the graph object 61, FIG. 14 is combined with the engine object 65 and the first table object 71, FIG. 15 is combined with the second table object 72.
A time object 75, various status icons 76, a speed object 77, and a compass icon 78 are arranged in a row in the horizontal direction in the upper area of the screen of the standby image P1. The time object 75 displays the current time. The various status icons 76 display a state obtained based on the vehicle location. The speed object 77 displays the current vehicle speed of the vehicle. The compass icon 78 serves as an index for displaying the direction of the traveling direction of the vehicle, and is a switching input unit for switching the display screen by operating the compass icon 78 on the display unit 14 as will be described later. A wireless character alarm display space 79 is provided in the lower area of the screen (an area surrounded by a two-dot chain line in the figure). The controller MC displays a warning display in the telop format in the wireless character alarm space 79 in accordance with the target data, radar detection data, etc. in the wireless character alarm display space 79. Since the warning display appears only in the wireless character alarm display space 79, it does not hinder the display of the change of the object that changes in the upper position. The warning display includes predetermined microwaves and radio waves received by the microwave detector 32 and the radio receiver 33, or predetermined information corresponding to the information based on position information of devices such as loop coils acquired in advance (here, For example, “LHsystem”) display is performed.

Here, as shown in FIG. 2, the display mode when three types of objects are displayed is arranged in a line with the same outer size in the horizontal direction. If the selected objects are the first to seventh meter objects 40, 45, 47, 49, 51, 55, 58, all are the so-called “triple meter style” with exactly the same outer dimensions of the surrounding ring 41. Will be displayed.
In order to inform the user what kind of driving information is displayed when three types are selectively displayed on the standby image P1, the controller MC is surrounded by a driving information display area 80 (indicated by a two-dot chain line in the figure). For each object that is displayed on the display area, the contents of the driving information displayed by the object are displayed in a Japanese name. In FIG. 14 (a), "fuel flow rate", "engine load factor", and "throttle opening" are displayed as operation information corresponding to the second, fifth, and sixth meter objects 45, 51, 55 selected and displayed as an example. It is displayed at the position of the area 80.
Display images actually developed on the display unit 14 of FIGS. 12 to 15 are FIGS. 18 to 21.

Next, a setting operation for setting a standby screen in such a radar detection device 10 will be described. Here, an example of setting the standby screen shown in FIG. 12 will be described.
First, a case where any three types of meters are selected from the first to seventh meter objects 40, 45, 47, 49, 51, 55, and 58 for the standby image P1 will be described. The user calls the main menu screen 81 shown in FIG. 16A from the display unit 14 that is a GUI input screen, and touches the “setting” icon 82 from the main menu screen 81 to display the hierarchical lower layers. A certain setting screen 83 is called (FIG. 17A). As a calling method, for example, it is assumed that the main menu screen 81 is displayed when continuous finger contact for a predetermined time (for example, 5 seconds) is detected at an arbitrary position on an arbitrary screen. Is done. Here, in order to set three types of meters, that is, a multimeter, the user touches the “OBD detailed setting” icon 84 on the display unit 14. Then, since an OBD detailed setting screen 85 as shown in FIG. 17B is displayed, the “multimeter selection” icon 86 is selected and touched.
A “multimeter selection” screen 87 as shown in FIG. 17C is displayed. In this screen 87, icons A to C are arranged in the order in which they are actually arranged in the standby image P1, and the correspondence relationship of the driving information of the vehicle is set at a position corresponding to the icons A to C. It is a specific selection screen which can select arbitrary driving information. When the user touches one of the icons A to C, a selection screen 88 in a lower hierarchy of “meter item selection” describing the vehicle driving information as shown in FIG. 17D is displayed. When any item is selected here, the screen automatically returns to “multimeter selection” in FIG. As shown in FIG. 17D, a selection completion notification such as a color change is performed to allow the user to understand that the icons A to C that have been selected have already been selected. At this time, the character information of the selected meter item may be displayed on the icon that has been selected. When the operation information to be displayed on all the icons A to C is selected repeatedly by repeating the operations in FIGS. 17C and 17D, the display unit 14 is on standby by touching the “main image” icon. The screen returns to the main screen where the screens are displayed and the settings are confirmed.

Next, a change setting operation for changing the standby screen will be described. In the present embodiment, there are two types: a first standby screen group based on vehicle driving information acquired uniquely by the radar detection device 10 and a second standby screen group based on vehicle driving information acquired from the vehicle diagnosis connector 22. Is prepared. Further, a map screen group is prepared as a function of the radar detection device 10.
Here, the second standby screen group means that the first to seventh meter objects 40, 45, 47, 49, 51, 55, 58, the graph object 61, the engine object 65, and the first table object. 71, four types of standby screens displayed in combination with the second table object 72 and the standby image P. Here, an operation of selecting a user's desired standby screen from the four types of standby screens will be described.
First, the user touches the “Map / Standby / OBD” icon 87 on the main menu screen 81 shown in FIG. 16B to select a predetermined screen to display a map screen group (map) and a first standby screen group. (Standby) or the second standby screen group (OBD) is selected. The icon 87 is a circular icon in which the selection target of the map / standby / OBD is switched by touching in order. Here, when a certain group is displayed on the screen and is not touched for a predetermined time (for example, 5 seconds), the currently displayed group is determined.
Here, OBD is selected in this embodiment. When OBD is selected, FIG. 12 is displayed as an initial screen. At this time, the three objects to be displayed are meter objects selected by the operations of FIGS. 17 (a) to 17 (d). The user can select a desired standby screen by touching the compass icon 74 and appropriately switching the display of FIGS. 12 to 15 (FIGS. 18 to 21). The compass icon 74 is a cyclic icon in which the four types of selection objects of the second standby screen group are switched by touching in order.

By configuring as described above, the following effects are exhibited in the present embodiment.
(1) In addition to the meter mounted on the vehicle, three types of driving information as important information for driving are displayed on the standby screen of the display unit 14 as meter objects. Can be performed. In addition, since the shape is displayed in meter format, it feels as if a new meter has been added to the meter that is purely mounted on the vehicle, and for car enthusiasts it is fun to drive while looking at these meters .
(2) Three types of driving information can be selected from eleven types (12 types including this and trip meter), and the driving information required can be arbitrarily changed and displayed as desired by the user. It is possible to obtain the optimum information according to the driving situation. Moreover, since there are over 1000 kinds of combination patterns, there is a pleasure in selecting and combining them.
(3) One type can be selected from a plurality of standby screens (four types in the embodiment) specialized for driving information, and one type can be selected from eleven types of meter objects by “multimeter selection”. Since the selection pattern of the standby screen is very large for the driving information, there is no need to get bored even with one model.
(4) In the first to seventh meter objects 40, 45, 47, 49, 51, 55, and 58, not only visual fluctuations but also numerical values of the current state are displayed together. The user can obtain more accurate information.
(5) Since all three types of meter objects displayed on the standby screen are displayed in the same size, the design is unified and easy to see.
(5) Since the type of information displayed by each meter object is displayed in Japanese at the lower position of each of the three types of meter objects displayed on the standby screen, it is possible to determine what the meter object is in an instant. I can understand.
(6) When a warning display is displayed in the telop format in the wireless character warning space 79, the warning display appears only in the wireless character warning display space 79 and does not hinder the object's change display, so always obtain driving information. Is possible.
(7) When the graph object 61 that graphs the correlation between the vehicle speed and the engine speed is displayed on the standby screen, the user generally obtains the correlation that cannot be obtained as driving information in real time as a history. It is very useful as driving information.
(8) When the graph object 61 is displayed on the standby screen, the history is appropriately deleted from the past, and only a certain past history is viewed, so the light spot of the history is not too much and small. Despite the screen, it is very easy to see.
(9) When the graph object 61 is displayed on the standby screen, the current position of the vehicle can be grasped as a position plotted at the intersection position P of the current position indication lines 62a and 62b, so that the current position is very easy to understand. At the same time, since the numerical values of the vehicle speed and the engine speed are displayed together with the instruction lines 62a and 62b, it is easy to grasp the accurate numerical values.
(10) The engine object 65 for variably displaying changes in both the engine speed and the engine load factor can be obtained only by one object without obtaining a plurality of objects. It is possible to display a relatively large variation object as compared with the case where each variation object is separately displayed on the screen, and it is advantageous because a plurality of variations can be simultaneously developed with a single variation object even on a small screen. . Further, since both the engine speed and the engine load factor can be obtained simultaneously as the operation information, it is very useful. In particular, since it is an object that imitates the interior of an impressive engine, it can give a very strong impression to what it sees.

The present invention may be embodied in the following manner.
In the above embodiment, an object corresponding to three types of driving information is selected by “multimeter selection”. However, for example, there may be two types or four or more types.
In the above embodiment, the external size of the three types of objects displayed on the standby screen by “multimeter selection” is the same size for each meter object. For example, only the main meter object is not the same. Can be displayed in a large size.
In the above embodiment, an object is selected from objects corresponding to 12 types of driving information by “multimeter selection”. However, in addition to these, for example, driving information that can be acquired only by GPS positioning is selected. The driving information acquired from other than the vehicle diagnosis connector 22 may be selected. Conversely, it may be possible to select only from the meter object. Moreover, you may employ | adopt driving information other than having mentioned by the said embodiment as driving information.
In the above embodiment, four types of standby screens are created by the standby image P1, but it is also possible to create standby screens other than these four types.
In the above embodiment, the graph object 61 and the engine object 65 are not combined with a plurality of meter objects as shown in FIG. 12, and are displayed as a single variable display unit. As described above, a plurality of variable display units may be displayed at the same time in place of other meter objects.
However, the graph object 61 may be displayed alone on the standby screen, but becomes considerably small when selected as one of the three types by “multimeter selection”. Therefore, when selected by “multimeter selection”, it is more preferable to display not the entire graph object 61 but only a narrow area including the current point.
In the above embodiment, the graph object 61 has the speed on the vertical axis and the engine speed on the horizontal axis. However, the present invention is not limited to this. The information can be combined appropriately as long as the information is correlated, such as the fuel flow rate on the vertical axis, the operating time on the horizontal axis, the engine load factor on the vertical axis, and the engine speed on the horizontal axis.
In the above description, the intersection position P of the current position indication lines 62a and 62b is used as a method for expressing the current position on the graph object 61. For example, the current position is changed from the light spot and the color of the past history, or the number of pixels is changed. You may make it show by other methods, such as increasing and expressing large.
In the above embodiment, the vehicle speed and engine speed acquired every second are plotted on the graph object 61, but other timings may be used. However, a time interval in which fluctuations in driving information can be accurately recognized is desirable.
In the above embodiment, the history on the graph object 61 has been deleted from the past 500 points or more, but it is free to change appropriately according to the size of the screen and the number of pixels occupied by one light spot. .
・ Regarding the history on the graph object 61, the past history is limited by limiting the existence time on the screen of one point (for example, about 5 minutes to 10 minutes) instead of limiting the number of simultaneously existing as described above. You may make it erase.
The scale up of the driving situation in the graph object 61 is two stages in the above embodiment, but it may be set to scale up or down in more stages. As described above, stepwise scale-up or scale-down is preferable because the scale does not change frequently and is easy to see. However, display that scales up or down steplessly is also possible.
The history in the graph object 61 is shown as an example for a vehicle having a speed change mechanism regardless of whether it is a manual or an AT car, but the speed change ratio is continuously changed like a continuously variable transmission (CVT). A history can be obtained in the same manner for a vehicle having such a transmission.
In the above embodiment, the engine load factor is expressed by changing the color of the piston object 67 of the engine object 65, but the color of the part other than the piston object 67 may be changed.
In the engine object 65 of the above embodiment, the change in the engine speed is expressed by the piston object 67 and the impeller object 70. However, other specific parts of the vehicle, for example, the change in the rotation speed of the crankshaft, the intake / exhaust valve You may make it apply to the speed change of the reciprocation of an object, and a cam, a cam shaft, and the rotation change of a tire.
-The present invention can be freely implemented in a modified form without departing from the spirit of the present invention.
