  As described above, a system that displays the vehicle information acquired from the vehicle in a meter is generally used.

JP 2007-54007 A

  However, when vehicle information is displayed by a meter, there is a problem that it is difficult to understand what vehicle information the meter indicates. In particular, when there are a plurality of meters or when the meter display is switched and displayed, this problem becomes significant.

  Accordingly, the present invention has been made to solve such problems, and an object thereof is to provide a display control system or the like that makes a display means a display that makes it easier for the driver to understand the state of the vehicle at a glance than before. And

  (1) In order to achieve the above-described object, a display control system according to the present invention is a display control system that performs control to acquire a vehicle state and display an object related to the acquired vehicle state on a display unit. The acquired object related to the vehicle state is an object having a shape of a part related to the acquired vehicle state, and display control is performed to change a display mode of the object according to the vehicle state.

  If it does in this way, a vehicle state can be understood at a glance by change of a display mode of an object which carried out shape of a part about an acquired vehicle state.

  The vehicle information may be acquired from the vehicle by connecting to, for example, an in-vehicle LAN, or may be acquired by providing a sensor or the like in the vehicle, or a sensor or the like is provided in the display control system. May be acquired.

In addition, the “part shape” may be the one that imitates the shape of the actual part so that a person who visually recognizes the part can see what the part shows, The shape of the part itself may be used.
The object may be, for example, an illustration, a photograph, a 3D object, or a combination thereof.

  (2) The display control for changing the display mode of the object according to the vehicle state is a mode simulating the actual state change of the part due to the change of the vehicle state for the object having the shape of the part related to the acquired vehicle state. It is preferable to adopt a configuration in which the control is changed by.

  The object may be configured as an object having a shape of a portion having a causal relationship with the generation of the acquired vehicle state. The object may have, for example, a shape of a part having a causal relationship that does not have a causal relationship in the generation of the acquired vehicle state. However, it is particularly preferable that the object has a shape of a part having a causal relationship.

  In this way, it is possible to know at a glance a part that has a causal relationship with the vehicle state from the shape of the object. Further, it is possible to grasp at a glance the state of a part having a causal relationship with the vehicle state from the display mode of the object.

  The actual change in the state of the part may be a change in the physical state of the part, for example, a change in the position of the part, a change in the movement speed of the part, or a change in temperature inside or outside the part. And as a mode that imitates the actual state change of the part, for example, the displayed part corresponding to the change of the position of the displayed part corresponding to the change of the position of the actual part, the change of the moving speed of the actual part It is preferable to change the color of the displayed part corresponding to the change in the movement speed of the body, the temperature inside or outside the actual part.

  (3) The vehicle state may be a state that varies depending on a vehicle operation of a person who can visually recognize the object displayed on the display means. In this way, it can be understood from the shape of the object what vehicle state is displayed, and the vehicle state is a state that varies depending on the vehicle operation of the person who can visually recognize the object. It can be reflected in the operation more quickly.

For example, an accelerator opening degree is acquired as a vehicle state, and an object having a foot shape corresponding to the inclination of the foot corresponding to the accelerator opening degree is used as a display control for changing the display mode of the object with a foot related to the acquired vehicle state as a foot. Control to move illustrations etc. is good.
(4) The display control may be configured to change the display in a manner that simulates a change in the actual vehicle state of the part.

  For example, the accelerator opening is acquired as the vehicle state, and the portion related to the acquired vehicle state is used as an accelerator pedal, and the shape of the accelerator pedal is set to the inclination of the accelerator pedal corresponding to the accelerator opening as display control for changing the display mode of the object. It is good to perform control to move the object (illustration etc.).

  In addition to the actual vehicle part, the display mode may be changed with the part indicating the operation state of the person who can visually recognize the object displayed on the display unit having a causal relationship to the change of the vehicle state as an object. Good. For example, the accelerator opening is acquired as the vehicle state, the “part related to the acquired vehicle state” is used as the accelerator pedal, and “the object displayed on the display means causally related to the change in the vehicle state is visually recognized. The object imitating the operator's foot is displayed as the `` part indicating the operation state '', and the display mode of both objects is the accelerator pedal corresponding to the accelerator opening and the object having the shape of the accelerator pedal in the inclination of the foot and the foot Control to move the object with the shape is good.

(5) The vehicle state is acquired as a value, and the display control for changing the display mode of the object according to the vehicle state includes display control for changing the display mode of the object according to the value of the vehicle state. It may be configured.
For example, the vehicle state may be a state A, a state B, or a state C, but may be acquired as a value.

  In this way, since the display mode of the object changes according to the value, an approximate value can be grasped intuitively.

  (6) The object may be an object indicating a schematic appearance of the part or an object indicating a schematic cross-sectional state of the part.

  In this way, it becomes easier to intuitively grasp the vehicle state at a glance. In particular, a person who can visually recognize the object displayed on the display means, such as a driver, may be an object that shows a schematic appearance of a part that cannot be visually recognized during driving or an object that shows a schematic sectional state. If it does in this way, the state of the part which cannot be visually recognized at the time of a driving | operation can be grasped | ascertained at a glance.

For example, the engine load may be acquired as the vehicle state, and the display mode of the object indicating the general appearance of the engine or the general engine cross-sectional state may be changed according to the engine load.
(7) The vehicle state may be an engine load, and the part may be an engine.

  This makes it easier for the driver to understand the state of the vehicle at a glance than before.

  (8) The object is composed of a plurality of partial objects, and the partial object includes a partial object that performs dynamic display and a partial object that performs static display. The partial object that performs dynamic display includes It is good to set it as the structure changed according to the said acquired vehicle state.

In this way, it is possible to grasp at a glance the object that performs dynamic display in relation to the object that performs static display. For example, when the dynamic display is performed by the movement of the object, the positional relationship of the dynamic object with respect to the static object can be grasped. Also, for example, when dynamic display is performed with the object color, the static object is fixed to a specific color, and the state of the dynamic object color can be easily grasped with respect to the static object color. Can do.
For example, an exterior part of the engine may be an object that performs static display, and a piston, a crank, or the like inside the engine may be an object that performs dynamic display.

  (9) A configuration in which at least one of the color, movement, display position, and size of the object is changed according to the vehicle state as display control for changing the display mode of the object according to the vehicle state; Good.

  (10) As display control for changing the display mode of the object according to the vehicle state, the color of the object may be changed, and the color of the object may be displayed darker as the vehicle state deteriorates.

  In this way, it is possible to grasp at a glance that the vehicle state is deteriorating from the color of the object, and it is also possible to simultaneously understand what the deteriorated vehicle state is about.

  (11) The object may be a 3D object, and as a display control for changing a display mode of the object according to the vehicle state, a state of a camera that captures the 3D object may be changed.

  (12) It is good to set it as the structure which acquires multiple said vehicle states and changes the display mode of the site | part from which the said object differs for every vehicle state.

  If it does in this way, change of a plurality of vehicles states can be grasped only by seeing one object. That is, a plurality of vehicle states can be easily grasped at a glance.

  For example, the engine load and the engine speed are acquired as the vehicle state, the engine is displayed as an object, the color of the piston of the engine is changed according to the engine load, and the rotation speed of the crankshaft is changed according to the engine speed. It is good to make it. In this way, the engine load and the engine speed can be grasped at a glance only by looking at the state of the engine object.

  (13) It is preferable to obtain a plurality of the vehicle states and change any one of the color, movement, display position, and size of the object that is different for each vehicle state.

The components (1) to (13) may be appropriately combined.
(14) The vehicle information display system according to any one of (1) to (13) may be configured as a program for causing a computer to realize the function.

This position history is recorded in the NMEA format, for example.
The standby screen display function is a function for displaying the speed, latitude, longitude, and altitude of the host vehicle detected by the GPS receiver 8 on the display unit 5 as shown in FIG.

  As shown in FIG. 3 (b), the radar scope display function is a position where a target within a predetermined range (for example, within a range of about 1 km) from the current position detected by the GPS receiver 8 is stored in the database 19. This is a function of searching based on information and displaying the relative positional relationship between the vehicle position and the position of the target on the display unit 5. In FIG. 3B, “W” on the left side indicates the west, “E” on the right side indicates the east, and “N” on the upper side indicates the north direction, and the horizontal line connecting “W” and “E” and “N” The icon at the intersection of the vertical line extending downward from "" indicates the vehicle position.

For example, when a control radio is received, a voice is output like “control radio. Speed attention”. During sound output, the alarm lamp 6 is turned on.

  In addition to these functions, the radar detector of the present embodiment has a vehicle information display function for displaying a vehicle information display screen as shown in FIG. The vehicle information display screen is a screen that mainly displays the engine load factor. As shown in FIG. 5, in the vehicle information acquired from the vehicle via the OBD2 connector as described above, in addition to the current value of the engine load factor, the current value of the throttle opening, the fuel flow rate, the instantaneous fuel consumption, Display of average fuel consumption, which is the average value of instantaneous fuel consumption obtained every second from when the detector is mounted on the vehicle to the present, and display of a 3D object indicating the shape of the engine according to the engine load factor The display is changed. Note that the average value of instantaneous fuel consumption is configured to be reset to 0 when the pressing of the reset button of the remote controller 17 is detected. A configuration menu or the like may be displayed to detect and reset the operation of the cross button or the like of the remote controller 17, and may be reset.

  When switched to the vehicle information display screen, a telop area consisting of a rectangular area having characters of “engine load factor” superimposed on the screen of FIG. 5 is displayed in the center of the screen for 3 seconds, and then the telop area is displayed. The process of deleting and displaying the screen as shown in FIG. 5 is performed.

  The vehicle information display screen has an engine object display area at the lower right as shown in FIG. In addition, an engine load factor display area, a throttle opening display area, a fuel flow rate display area, and an instantaneous fuel consumption display area are provided on the left side of the engine object display area from the top, and an average fuel consumption display area is provided above the engine object display area. .

  In the engine load factor display area, throttle opening display area, fuel flow rate display area, instantaneous fuel consumption display area, and average fuel consumption display area, the name of each vehicle information is displayed in letters on the left side, and the value and unit of the value on the right side The vehicle information name and the current value display area are displayed below the characters.

  In the example of FIG. 5A, the engine load factor display area displays the characters “engine load factor” as its name, and the value “16” and its unit “%” on the right side. Is displayed. In addition, in the throttle opening display area, the letter “throttle opening” is displayed as its name, and “11” which is the value of the value and “%” which is the unit thereof are displayed on the right side thereof. In the fuel flow rate display area, the name “fuel flow rate” is displayed as its name, and the value “34” and the unit “ml / m” are displayed on the right side thereof. Similarly, in the instantaneous fuel consumption display area, the word “instant fuel consumption” is displayed as the name, and the value “6.3” and the unit “km / l” are displayed on the right side. ing. In addition, in the average fuel consumption display area, “average fuel consumption” is displayed as its name, and the value “7.0” and its unit “km / l” are displayed on the right side thereof. Yes.

  The engine object display area is an area that is displayed by changing the display mode of a 3D object (hereinafter also referred to as an engine object) indicating the shape of the engine according to the magnitude of the engine load factor. This 3D object is an object simulating the outer diameter shape of the engine, and includes an engine exterior, a manifold (supply / exhaust pipe), a timing belt, a cooling fan, and the like. Rendering is performed by setting the camera angle of view and light source so that the entire engine exterior and the entire cooling fan enter the engine object display area and can be seen. The center of the 3D object is the origin, the screen horizontal direction is the X axis, the screen vertical direction is the Y axis, and the screen depth direction is the Z axis.

  As a change in the display mode, the engine object is displayed in a stationary state when the engine load is 0%, and when the engine load is not 0%, the engine object is displayed in a counterclockwise direction with the Y axis as the center when viewed from above. A process of changing the display angle of the engine object in a range of plus or minus 10 degrees as the plus direction is performed. FIG. 5A shows an engine object at a position of 0 degrees. The angle change period is shortened as the engine load approaches 100%. Specifically, the change from 0 to +10 to 0 degrees to -10 degrees to 0 degrees (one cycle) is performed five times per second (once every 200 ms) when the maximum engine load is 100%. Thus, this cycle is changed in proportion to the engine load. Instead of changing the cycle, the cycle may be constant (for example, 5 times per second), and the amplitude of the display angle may be changed according to the engine load factor. For example, when the engine load factor is 0%, the swing width is 0 degree, the swing width is increased as the engine load ratio approaches 100%, and finally the swing width is increased or decreased by 10 degrees when the engine load is 100%. You may do it. It is desirable to display in an exaggerated manner as much as possible from the actual movement of the engine due to fluctuations in the engine load factor. For example, it is even better to display the engine so that the engine falls over when the engine load factor increases.

  Further, as a change in the display mode, the color of the engine object is changed according to the engine load factor as shown in FIG. The color of the engine block portion (the lower portion of the engine) is changed as shown in FIG. 6 (a), and the color of the manifold portion is changed as shown in FIG. 6 (b). In FIG. 6, the solid line is the ratio of red color (unit%), the broken line is the ratio of green color (unit%), and the alternate long and short dash line is the ratio of blue color (unit%). In the pattern of FIG. 6A, blue is always 0%, and when the engine load factor is 55%, the ratio of green is 100%. When the engine load factor exceeds 55%, it reaches 85%. Decrease the percentage of green and set 0% at 85% to 0% until 100%. On the other hand, red indicates that the engine load factor is 0% from 0% to 30%, and the engine load factor increases from 30% to 65% as the engine load factor increases. In the above, red is maintained as a ratio of 100%. The pattern shown in FIG. 6B is also a pattern in which red is increased as the engine load factor is increased and green is decreased as the engine load factor is increased. The details are as shown in the graph.

  Further, as a change in display mode, the cooling fan object constituting the engine object stops when the engine load factor is 0%, and rotates so that the fan appears to rotate when the engine load factor is not 0%. Let The number of revolutions of the object of the cooling fan is increased as the engine load factor increases. This cycle is changed in proportion to the engine load so that 5 rotations per second (1 rotation in 200 ms) are performed when the engine load factor is 100%.

  As a result of the process of changing the display mode, when the engine load is 0%, the engine object appears stationary in green and the cooling fan object appears stationary. As the engine load approaches 100%, the engine object appears stationary. As the object turns red, the intensity of shaking appears to increase and the number of revolutions of the object of the cooling fan appears to increase. For example, as shown in FIG. 5 (a), when the engine load factor is 16%, the engine object looks green and almost no shaking is felt, and the rotation of the object of the cooling fan is felt relaxed. However, as shown in FIG. 5B, when the engine load factor becomes 51%, the engine object looks yellow-green and feels swaying and the object of the cooling fan can be quickly felt. Then, as shown in FIG. 5C, when the engine load factor becomes 81%, the engine object looks red and feels swaying violently and the rotation of the object of the cooling fan is also felt violently rotating. .

  In the above-described embodiment, the 3D object is an object indicating the outer shape of the engine. However, the 3D object is not limited to this and can take various forms. The numerical value display section can also take various forms.

  For example, as shown in FIGS. 7 (a) to 7 (c) and FIGS. 8 (a) to 8 (d), the left side is displayed in the form of the cross-sectional shape of the engine, and the vehicle information value is displayed on the right side. A numerical value may be displayed. Although the numerical values in FIGS. 7 and 8 are dummy numerical values, values corresponding to the vehicle information may be displayed by the same processing as shown and described in FIG.

  7 and 8 includes a first object that dynamically displays a piston, a crank, and the like inside the engine, and a second object that statically displays an exterior part of the engine.

  The first object is a part composed of a piston, a connecting rod, a crankshaft, etc., and the piston moves up and down by the combustion of fuel in the combustion chamber of the engine, and the vertical movement of the piston is rotated by the crank. The situation is shown by 3D animation, and FIG. 7 (a), FIG. 7 (b), FIG. 7 (c), FIG. 8 (a), FIG. 8 (b), FIG. 8 (c), FIG. ) In order of the objects so that changes can be seen.

  On the other hand, the second object is an engine exterior part, such as FIG. 7A, FIG. 7B, FIG. 7C, FIG. 8A, FIG. 8B, FIG. This is a 3D object that does not move even when the first object moves in this order.

  For example, the rotation of the crankshaft is changed in accordance with the engine load factor in the same manner as the movement of the cooling fan described with reference to FIG. 5, and the piston is moved in accordance with the movement of the crankshaft (FIGS. 7 and 8). It is recommended to change the position of the first object (as shown). Further, instead of changing according to the engine load factor, it may be displayed so that the crankshaft is rotated in accordance with the engine speed acquired as the vehicle information. For example, it is good to display so that a crankshaft may be rotated at the speed of 1/10 of engine speed. Further, only the color of the first object is changed in the same way as the change of the engine color described in FIG. 5, or the color of the first object is displayed in monotone and the engine load is 0%. In this case, the red component may be displayed as 0%, and the red component may be displayed as 100% when the engine load is 100%.

Therefore, the engine load factor can be understood at a glance by the change in the display mode of the object having the shape of the engine as the portion related to the acquired engine load factor.

In this embodiment, vehicle information such as the engine load factor is acquired from the vehicle. However, a sensor or the like may be provided in the vehicle, or a sensor or the like may be provided in the radar detector. You may make it acquire.
In the present embodiment, the object is a 3D object, but may be an illustration, a photograph, or a combination thereof.

  In the present embodiment, as the display control for changing the display mode of the 3D object according to the engine load factor, the actual engine of the engine object having the shape of the engine, which is a part related to the acquired engine load factor, is determined by the change of the engine load factor. It is controlled to change in a manner simulating the state change. As the engine load factor increases, the vibration becomes more intense and the internal temperature increases. The whole or part of the engine object is moved to simulate the intensity of this vibration, and the internal temperature is also increased to change the color to red.

  The actual change in the state of the engine is not limited to that shown in the present embodiment, but may be a change in the physical state of the engine or its components. For example, the position or movement of the engine or its components may be changed. It may be a change in speed or a change in internal or external temperature. And as a mode simulating the actual engine state change, for example, the change of the position of the displayed object corresponding to the change of the position of the actual engine or its component, the change of the moving speed of the actual engine or its component The change in the moving speed of the object corresponding to the above, the change in the color of the displayed portion corresponding to the change in the internal or external temperature of the actual engine or its components, and the like may be used.

  In this embodiment, as the display control for changing the display mode of the object according to the engine load factor, the color, movement, and display position of the object are changed. For example, the size and shape of the object, the 3D You may make it change the state of the camera which image | photographs an object, and the state of a light source. These may be configured in combination.

  In the present embodiment, as the display control for changing the display mode of the object according to the engine load factor, the color of the object is changed, and the color of the object is displayed darker as the engine load factor deteriorates. Yes. Therefore, it can be grasped at a glance from the color of the object that the vehicle state is deteriorating, and at the same time, what the deteriorating vehicle state is about.

  In the present embodiment, display control is performed in which the value of the engine load factor is acquired as the vehicle state, and the display mode of the 3D object is changed according to the value. Thus, since the color and movement of the engine object change according to the value of the engine load factor, an approximate value can be intuitively grasped.

  In the embodiment shown in FIGS. 7 and 8, the engine load factor and the engine speed are acquired as the vehicle state, the engine is displayed as an object, the color of the engine piston is changed according to the engine load, and the engine speed is changed. The rotational speed of the crankshaft is changed according to the number. Therefore, the driver can grasp the engine load and the engine speed at a glance only by looking at the state of the engine object. In this way, a change in a plurality of vehicle states can be grasped only by looking at one object.

  In the embodiment shown in FIGS. 7 and 8, the object is composed of a plurality of partial objects, and the partial objects include a first object that performs dynamic display and a second object that performs static display.
