To do. When it is determined that the information processing device 1 has exceeded, the output mode on the display unit 20 of the first gauge portion G1 corresponding to the excess region is a part of the output mode of the corresponding gauge G when not exceeding Control differently.

  The information acquisition unit 10 acquires information related to the traveling environment of the vehicle.

The information acquisition unit 10 may acquire information on at least one of the front vehicle situation, the rear vehicle situation, the parallel running vehicle situation, and the crossing vehicle situation. In addition, the information acquisition unit 10 may acquire environmental information around the vehicle, such as information related to the communication state with the external network, information related to the situation of moving objects in the vicinity, external server information, and POI (Point Of Interest) information. Good.

  The information acquisition unit 10 may include a navigation system. In this case, the information acquisition unit 10 calculates the current position of the host vehicle indicated by the latitude, longitude, altitude, inclination, lane position, etc. of the vehicle. Moreover, the information acquisition part 10 may acquire the information regarding the own vehicle position condition, such as temperature, humidity, the weather, brightness, and transparency in the present position of the own vehicle.

  In addition to this, the information acquisition unit 10 may acquire information related to various driving environments of the vehicle. The information acquisition part 10 may acquire the information regarding various vehicle situations, for example using the controller area network (CAN) which is one communication system in a vehicle-mounted network. For example, the information acquisition unit 10 includes the vehicle speed, the accelerator state, the brake state, the clutch state, the winker state, the gear state, the wiper state, the door mirror state, the seat state, the audio state, the warning state, the light state, the steering state, and the idle state. Information on the vehicle status such as the air conditioner state, the seat belt state, and the driving operation level may be acquired.

  The information acquisition unit 10 may also acquire information related to the driver. For example, the information acquisition unit 10 may acquire information related to the driver's state such as the driver's face direction, line of sight, and blinking state.

  The above information acquired by the information acquisition unit 10 is output to the control unit 30. The above information acquired by the information acquisition unit 10 may be stored in the storage unit 40 as necessary.

  The display unit 20 displays the display information output from the control unit 30. That is, the display unit 20 displays information on the traveling environment of the vehicle acquired by the information acquisition unit 10. The display unit 20 has at least one screen. The display unit 20 may be configured by an arbitrary display device such as a liquid crystal display. When the display unit 20 is configured by a liquid crystal display, the display unit 20 is disposed, for example, on an instrument panel. The display device constituting the display unit 20 may be a touch panel display or a display incapable of touch operation.

  The display part 20 is comprised by three screens as an example (refer FIG. 1). That is, the display unit 20 includes a head-up display (HUD) 21, a meter display 22 and a center display 23. The HUD type device including the HUD 21 has a light emitting unit that generates display information as display light, reflects the generated display light toward an observer such as a driver, and displays a virtual image through the front windshield. To do. The observer is not limited to the driver, and may be a passenger sitting in the passenger seat. The meter indicator 22 and the center indicator 23 are arranged on the instrument panel.

  The control unit 30 is a processor that controls and manages the entire information processing apparatus 1 including each functional block of the information processing apparatus 1. The control unit 30 includes a processor such as a CPU (Central Processing Unit) that executes a program that defines a control procedure. Such a program is stored in the storage unit 40, for example.

  The control unit 30 refers to various information stored in the storage unit 40 as necessary. Specifically, the control unit 30 refers to the information related to the traveling environment of the vehicle. The control unit 30 controls the display unit 20 to display necessary information as appropriate.

  The storage unit 40 can be configured by a semiconductor memory, a magnetic memory, or the like. The storage unit 40 stores the above-described various information, a program for operating the information processing apparatus 1, and the like. The storage unit 40 also functions as a work memory.

  Hereinafter, information processing performed by the information processing apparatus 1 will be described in detail. First, the information displayed on the meter display 22 will be described in detail with reference to FIGS. FIG. 3 is a schematic diagram illustrating a first example of an image displayed on the meter display 22. FIG. 4 is a schematic diagram illustrating a second example of an image displayed on the meter display 22. FIG. 5 is a schematic diagram illustrating a third example of an image displayed on the meter display 22.

  As shown in FIGS. 3 to 5, the meter display 22 displays a circular speedometer on the left half thereof. That is, the meter display 22 displays the vehicle speed and the speed limit based on the information related to the traveling environment of the vehicle acquired by the information acquisition unit 10. As an example, the meter display 22 may display the current vehicle speed as a numerical value at the center of the speedometer. At the same time, the meter display 22 may display a gauge G indicating the current vehicle speed and the speed limit on the circumference of the speedometer. The meter indicator 22 may display a scale provided at equal intervals in the gauge G. The meter indicator 22 may display a numerical value of speed at a corresponding position on the inner peripheral side of the gauge G with respect to a predetermined scale in the gauge G. The meter display 22 may display the speed limit as an image imitating an actual road traffic sign image. In particular, the meter display 22 may superimpose and display the speed limit determined on the traveling road on the numerical value of the corresponding speed displayed on the inner peripheral side of the gauge G. The meter indicator 22 may display a pointer N indicating the current vehicle speed.

  The control unit 30 determines whether or not the current vehicle speed exceeds the speed limit based on the information regarding the vehicle speed and the speed limit acquired by the information acquisition unit 10. When it is determined that the current vehicle speed does not exceed the speed limit, the control unit 30 may perform the following control.

  That is, the control unit 30 differs the area in the gauge G from 0 km / h to the current vehicle speed from the other areas in the gauge G based on the information on the vehicle speed acquired by the information acquisition unit 10. You may display by a color. For example, the control unit 30 clearly displays an area in the gauge G from 0 km / h to the current vehicle speed in a state where the brightness is increased by two colors of black and white, while other areas in the gauge G are You may display in the state which visibility reduced by grayout etc. At the same time, the control unit 30 may display the pointer N so as to indicate the position of the gauge G corresponding to the current vehicle speed.

  Note that “color” includes various elements such as luminance, hue, saturation, lightness, gradation, and number of types. That is, “the color is different” and “the color changes” mean that at least one of these various elements is different or changes. Hereinafter, as an example, the “color” to be displayed is specifically described as appropriate by limiting it to two colors of black and white, a warm color, and the like, but is not limited thereto. The control unit 30 may control the color related to the display target by an appropriate method including adjustment of the various elements described above.

  When it is determined that the current vehicle speed exceeds the speed limit, the control unit 30 may perform the following control.

  That is, the control unit 30 performs control so that the output mode of the first gauge portion G1 corresponding to the excess region is different from the output mode of a part of the corresponding gauge G when it does not exceed. Here, the excess region means a speed region from the speed limit to the current vehicle speed exceeding the speed limit. The first gauge portion G1 can be defined when the speed of the vehicle exceeds the speed limit, and means a gauge area corresponding to the excess area of the gauge G.

  In particular, when the speed of the vehicle exceeds the speed limit, the control unit 30 may control the color of the first gauge portion G1 to be different from the color of a part of the corresponding gauge G when it does not exceed the speed limit. Good. More specifically, the control unit 30 may perform control so that the color of the first gauge portion G1 is different from the color when the gauge region corresponding to the speed region larger than the speed limit is not exceeded. For example, as shown in FIG. 3, a case is considered in which the speed limit of a running road is 80 km / h and the current vehicle speed is 96 km / h. At this time, the 1st gauge part G1 is defined by the gauge area | region corresponding to the speed area | region larger than 80 km / h and below 96 km / h among the gauges G. When the speed of the vehicle does not exceed the speed limit, the control unit 30 controls the output mode so that the meter display 22 displays a part of the gauge G corresponding to the first gauge part G1, for example, in gray out. . More specifically, the control unit 30 controls the output mode so that the meter indicator 22 displays the entire region of the gauge G corresponding to the velocity region larger than 80 km / h by grayout. In this state, when the speed of the vehicle exceeds the speed limit, the control unit 30 changes the first gauge portion G1 corresponding to the speed region that the meter indicator 22 has exceeded from, for example, grayout such as yellow, orange, and red. Control to display by warm color.

  Further, the control unit 30 determines a second gauge portion G2 corresponding to a speed region other than the excess region. For example, in the speedometer shown in FIG. 3, the second gauge portion G2 is a gauge region other than the first gauge portion G1 corresponding to a speed region of greater than 80 km / h and less than or equal to 96 km / h. That is, as an example, the second gauge portion G2 is configured by a gauge region corresponding to 0 km / h or more and 80 km / h or less and a gauge region corresponding to greater than 96 km / h and 260 km / h or less.

  Thus, in the situation where the second gauge portion G2 is displayed together with the first gauge portion G1, the control unit 30 displays the meter so that the color of the first gauge portion G1 is different from the color of the second gauge portion G2. The device 22 may be controlled. For example, in the speedometer shown in FIG. 3, the control unit 30 displays the second gauge portion G2 on the meter display 22 by adjusting the density, brightness, and the like according to two colors of black and white. More specifically, in the gauge region corresponding to 0 km / h or more and 80 km / h or less in the second gauge portion G2, the control unit 30 displays clearly with the brightness increased, while 96 km / h. The gauge region corresponding to greater than or equal to 260 km / h is displayed in gray out. In any region, the second gauge portion G2 is displayed in two colors of black and white. As described above, the second gauge portion G2 is displayed by two colors of black and white, while the first gauge portion G1 is displayed by a warm color different from the two colors of black and white.

  In a situation where the meter indicator 22 also displays the pointer N indicating the current vehicle speed, the control unit 30 controls the meter indicator 22 so that the color of the first gauge portion G1 is different from the color of the pointer N. May be. For example, in the speedometer shown in FIG. 3, the control unit 30 clearly displays the pointer N in a white state with increased brightness. Thus, while the pointer N is displayed in white, the first gauge portion G1 is displayed in a warm color different from white.

  The control unit 30 may perform control so that the color of the first gauge portion G1 depends on the size of the excess region. For example, the color of the first gauge portion G1 may change to a warm color that increases the alertness as the excess region increases. As an example, the control unit 30 may change the color of the first gauge portion G1 in the order of yellow, orange, red, etc., as the excess region increases. The control unit 30 may continuously change the color of the first gauge portion G1, or may change the color of the first gauge portion G1 discontinuously. When the color of the first gauge portion G1 is continuously changed, the control unit 30 may change the color at an appropriate change rate. When changing the color discontinuously, the control unit 30 may change the color stepwise for each appropriate speed region.

  Although the control part 30 demonstrated as what displays the area | region corresponding to the gauge G by a different color depending on whether the speed of the vehicle exceeded the speed limit, it is not limited to this. For example, the control unit 30 may not display a part of the corresponding gauge G when the speed of the vehicle does not exceed the speed limit, and may display the first gauge part G1 when exceeding. The “output mode” of the first gauge portion G1 and a part of the corresponding gauge G described above means turning on or off the display in this case.

  For example, as shown in FIG. 4, when the speed of the vehicle does not exceed the speed limit, the control unit 30 may hide the area of the gauge G corresponding to the speed area that is larger than the speed limit. More specifically, let us consider a case where the speed limit of a running road is 80 km / h and the current vehicle speed is 60 km / h. In this case, the control unit 30 clearly displays an area in the gauge G from 0 km / h to 60 km / h or less in a state in which the luminance is increased by two colors of black and white, while being larger than 60 km / h and 80 km / h. The area of the gauge G below h is displayed in a state in which the visibility is lowered by grayout or the like. Further, the control unit 30 does not display the area of the gauge G that is greater than 80 km / h.

  When the vehicle speed exceeds the speed limit in such a state, the control unit 30 displays the first gauge portion G1. For example, as shown in FIG. 5, a case is considered in which the speed limit of a running road is 80 km / h and the current vehicle speed is 96 km / h. In this case, the control unit 30 clearly displays an area in the gauge G from 0 km / h to 80 km / h or less in a state where the luminance is increased by two colors of black and white. Further, the control unit 30 displays the first gauge portion G1 of greater than 80 km / h and less than or equal to 96 km / h with a warm color. In addition, the control part 30 does not yet display the area | region of the gauge G larger than 96 km / h.

  Next, information displayed on the HUD 21 will be described in detail with reference to FIG. FIG. 6 is a schematic diagram illustrating an example of an image displayed on the HUD 21.

  As shown in FIG. 6, the HUD 21 may display the current vehicle speed as a numerical value at the center thereof. The HUD 21 may simultaneously display the speed limit and the set speed of the running road on one bar at the bottom. Here, the set speed may be, for example, a speed set by a driver or the like using ACC, or may be a speed set by the driver or the like when performing automatic driving. Further, the HUD 21 may display a bar so as to correspond to the entire range of the speed region that can be set, or may display a bar so as to correspond to an arbitrary partial range centering on the speed limit. Good. The HUD 21 may display the speed limit as an image imitating an actual road traffic sign image. In particular, the HUD 21 may display the speed limit determined on the road that is running in an overlapping manner on the bar. In addition, for example, the HUD 21 may display the planned route on the left end based on the route information acquired from the navigation system, or may display the current driving state on the right end.

  For example, when the control unit 30 acquires information about an input operation of a driver or the like using an arbitrary input device, the control unit 30 may change the display of the set speed on the bar displayed on the HUD 21 in response to the input operation. Good. For example, as shown in FIG. 6, when the driver or the like performs an operation to increase the set speed in a state where the set speed is 70 km / h, the control unit 30 sets the numerical value on the bar and the position corresponding to the operation. It may be changed. If the HUD 21 is a display that can be touch-operated, the control unit 30 adds “−” and “+” button displays to the left and right ends of the bar, respectively. The display of the set speed may be changed based on the touch operation.

  FIG. 7 is a flowchart illustrating an example of the operation of the information processing apparatus 1 according to an embodiment.

  The control unit 30 acquires information on the current vehicle speed and the speed limit from the information acquisition unit 10 (step S10).

  The control unit 30 determines whether or not the current vehicle speed exceeds the speed limit (step S11). When it is determined that the current vehicle speed does not exceed the speed limit, the control unit 30 proceeds to step S12. When it is determined that the current vehicle speed exceeds the speed limit, the control unit 30 proceeds to step S13.

  When the current vehicle speed does not exceed the speed limit, the control unit 30 increases the brightness of the corresponding gauge region (step S12). For example, the control unit 30 clearly displays an area in the gauge G from 0 km / h to the current vehicle speed in a state where the luminance is increased by two colors of black and white.

  When the current vehicle speed exceeds the speed limit, the control unit 30 displays the first gauge portion G1 (step S13). For example, the control unit 30 displays the first gauge portion G1 with a warm color.

  The control unit 30 returns to step S <b> 10 and acquires again information on the current vehicle speed and the speed limit from the information acquisition unit 10.

  The information processing apparatus 1 as described above can improve the driver's recognition for exceeding the speed limit. That is, since the output mode of the first gauge portion G1 is different from the output mode of a part of the corresponding gauge G when it does not exceed, the driver can intuitively recognize that the speed limit is exceeded.

  Since the color of the first gauge portion G1 is different from the color of a part of the corresponding gauge G when the information processing device 1 does not exceed the information, the information processing device 1 can improve the driver's visibility and To alert you to exceeding the speed limit. In particular, the information processing apparatus 1 displays the first gauge portion G1 with a warm color from a grayed-out state, so that the driver can be more alert.

  The information processing apparatus 1 can display the first gauge portion G1 from a state in which a part of the corresponding gauge G is not displayed, thereby allowing the driver to recognize the difference before and after being more emphasized. In particular, the information processing apparatus 1 can cause the driver to be more alert when the first gauge portion G1 is suddenly displayed with a warm color.

  The information processing apparatus 1 can display the first gauge portion G1 in a state that makes the first gauge portion G1 more prominent in the entire gauge G by making the color of the first gauge portion G1 different from the color of the second gauge portion G2. Thereby, even if the driver visually recognizes the entire speedometer, the driver can recognize at a glance that the speed limit has been exceeded. In particular, the information processing apparatus 1 displays the second gauge portion G2 in two colors, black and white, while displaying the first gauge portion G1 in a warm color, thereby giving the driver the first gauge portion G1. Can be recognized in a more emphasized state.

  The information processing apparatus 1 can improve the visibility of the first gauge portion G1 and the pointer N by making the color of the first gauge portion G1 different from the color of the pointer N. That is, the driver can easily recognize the overlap between the first gauge portion G1 and the pointer N. In particular, the information processing apparatus 1 can further emphasize the display of the pointer N with respect to the first gauge portion G1 by displaying the first gauge portion G1 in a warm color and displaying the pointer N in white.

  The driver can easily recognize a difference from the speed limit because the color of the first gauge portion G1 depends on the size of the excess region. In particular, the information processing apparatus 1 can improve the driver's awareness of speed regulation by changing the color to a warm color that increases the alertness as the excess region increases.

  The information processing apparatus 1 can improve the recognizability of these differences for the driver by displaying the speed limit and the set speed on one bar. That is, the driver can intuitively recognize the difference between these two speeds as the distance on the bar.

  Although the present invention has been described based on the drawings and examples, it should be noted that those skilled in the art can easily make various changes or modifications based on the present disclosure. Therefore, it should be noted that these variations or modifications are included in the scope of the present invention. For example, the functions included in each means, each step, and the like can be rearranged so as not to be logically contradictory, and a plurality of means or steps can be combined into one or divided. .

  3 to 5, the meter display 22 has been described as displaying the second gauge portion G2 and the pointer N, but is not limited thereto. The control unit 30 may control the display of the meter indicator 22 by any method that allows the driver to recognize the current vehicle speed. For example, the meter indicator 22 may display only one of the second gauge portion G2 and the pointer N.
