  An embodiment according to the present invention will be described with reference to the drawings. In addition, this invention is not limited by the following description and drawing. Needless to say, modifications (including deletion of components) can be added as appropriate to the configurations shown in the following description and drawings. Moreover, in the following description, in order to make an understanding of this invention easy, description of a known technical matter is abbreviate | omitted suitably.

  A configuration of a vehicle 1 according to an embodiment of the present invention will be described with reference to FIG. The vehicle 1 is an electric vehicle, and main components for explaining the present embodiment are a power unit 3, a tire 5, a battery 7, an accelerator 9, a display control device 11, and a vehicle control unit 13. And including.

  The power unit 3 includes a motor and a gear that transmits the power of the motor to the outside of the power unit 3. The power of the motor is transmitted to a shaft (not shown) through a gear. By this transmission, the shaft rotates, the tire 5 rotates by this rotation, and the vehicle 1 travels. In this way, the power unit 3 rotates the tire 5 via the shaft and causes the vehicle 1 to travel. The power unit 3 is controlled by the vehicle control unit 13 (control device 131).

  The battery 7 stores electric power, which is energy for operating predetermined components in the vehicle 1, and supplies the electric power to the predetermined components. In particular, the motor of the power unit 3 is driven by electric power supplied from the battery 7.

  The accelerator 9 receives an accelerator operation from the user. The accelerator 9 supplies, for example, an accelerator operation signal indicating a value corresponding to an operation amount (for example, a depression amount) of an accelerator operation to the vehicle control unit 13 (control device 131).

  The vehicle control unit 13 includes a control device 131, a revolution meter 132, and a fuel gauge 133. The tachometer 132 is used to measure the number of rotations of the tire. The fuel gauge 133 is for measuring the remaining amount of energy stored in the battery (remaining capacity (Ah) in this embodiment). The remaining amount may be represented by, for example, power. In this case, the processing described later is appropriately performed based on the power.

  The control device 131 performs various controls. The control device 131 is supplied with an accelerator operation signal. The control device 131 controls the power unit 3 so that the vehicle 1 travels at a speed corresponding to the magnitude of the value indicated by the accelerator operation signal. For example, the control device 131 controls the power unit 3 by controlling the amount of power supplied to the motor, thereby controlling the magnitude of the output of the motor, the magnitude of the power output by the power unit 3, and the like. As a result, the vehicle 1 travels at a speed corresponding to the operation amount of the accelerator operation.

  Here, the control device 131 is set to one of a plurality of travel modes. A method for setting the travel mode will be described later. The control device 131 controls the power unit 3 (particularly, the amount of power supplied to the motor, the gear ratio, etc.) also in accordance with the set travel mode. That is, even if the operation amount of the accelerator operation is the same, if the traveling mode is different, the power output from the power unit 3, the gear ratio, and the like are different, and the traveling speed, acceleration, and the like of the vehicle 1 are different. The travel mode designates response characteristics of accelerator operation in the vehicle 1. That is, here, the vehicle 1 travels at a speed and acceleration corresponding to the response characteristics of the travel mode set in the control device 131. As a result, the vehicle 1 travels in the set travel mode.

  As the running mode, there are a “NORMAL” mode, an “ECO” mode, a “SPORTS” mode, and the like.

  The “NORMAL” mode is a mode in which the vehicle 1 travels at a speed and acceleration based on normal response characteristics with respect to the amount of accelerator operation.

  The “ECO” mode is a mode in which the output of the motor is suppressed and the speed and acceleration of the vehicle 1 are reduced with respect to the operation amount of the accelerator operation, compared to the “NORMAL” mode. In this mode, in general, the fuel consumption of the battery 7 (here, the power consumption rate) is better than the “NORMAL” mode.

  The “SPORTS” mode is a mode in which the power output from the power unit 3 is larger than the “NORMAL” mode, and the speed and acceleration of the vehicle 1 are increased with respect to the amount of accelerator operation. In this mode, the fuel efficiency of the battery 7 is generally worse than in the “NORMAL” mode.

  Further, the control device 131 sequentially measures the number of revolutions for each first predetermined period using the revolution number meter 132 and sequentially supplies the measured number of revolutions (number of revolutions information) to the display control device 11. Further, the control device 131 sequentially measures the remaining amount of energy of the battery 7 using the fuel gauge 133 every second predetermined period, and displays the measured remaining amount (remaining amount information) of the battery. To supply sequentially. The first predetermined period and the second predetermined period are basically the same, but may be different.

  The display control device 11 calculates a fuel consumption based on information supplied from the control device 131 and displays a predetermined display screen. Further, the display control device 11 sets the travel mode in the vehicle 1 by setting the travel mode in the control device 131. Here, the display control device 11 is an instrument (vehicle instrument) that displays the speed of the vehicle 1 or the like.

  The display control device 11 includes a control unit 111, a storage unit 112, an input / output interface unit 113, a display unit 114, and an operation unit 115.

  The input / output interface unit 113 includes an interface that mediates exchange of information between the display control device 11 and the vehicle control unit 13, and also includes an interface that mediates display control to the display unit 114 performed by the control unit 111. The input / output interface unit 113 includes an interface that mediates when the operation unit 115 supplies operation information to the control unit 111.

  The display unit 114 is configured by an appropriate display device such as a liquid crystal display or an EL display. The display unit 114 is controlled by the control unit 111 via the input / output interface unit 113 and displays predetermined information.

  The operation unit 115 includes various keys and is used for selecting a travel mode. For example, when the user operates the operation unit 115 to select a travel mode, operation information (travel mode selection operation information) corresponding to this operation is supplied to the control unit 111 via the input / output interface unit 113.

  The storage unit 112 stores predetermined information and the like. The storage unit 112 includes a flash memory 112a and a ROM (Read Only Memory) 112b. In addition to recording the program, the ROM 112b appropriately stores information (various data) used for processing performed by the control unit 111. The information recorded in the ROM 112b is read into the RAM of the control unit 111, for example. The flash memory 112a appropriately stores information generated by the control unit 111.

  The control unit 111 includes a remaining amount acquisition unit 111a, a remaining travel distance specification unit 111b, a display control unit 111c, a fuel consumption calculation unit 111d, and a travel mode setting unit 111e.

  The control unit 111 (that is, each unit described above) includes a CPU (Central Processing Unit), a RAM (Random Access Memory), and the like. The CPU actually performs processing performed by each unit of the control unit 111 according to the program recorded in the storage unit 112 and using information recorded in the ROM 112b and the like. The RAM appropriately stores information used by the CPU, information generated by the CPU, and the like. Further, a program to be described later may be read once into the RAM. At least a part of the control unit 111 may be configured by an application specific integrated circuit (ASIC), a digital signal processor (DSP), or the like.

  The travel mode setting unit 111 e receives travel mode selection operation information supplied from the operation unit 115 to the control unit 111, and supplies information on the travel mode selected by the user, which is specified by this information, to the control device 131. The control device 131 sets the travel mode of this information as the current travel mode. In the present embodiment, the travel mode is set in the control device 131 (vehicle 1) by the control unit 111 (travel mode setting unit 111e) in this way. The vehicle 1 travels in this travel mode. The travel mode setting unit 111e appropriately stores predetermined information so that the currently set travel mode can be specified. Accordingly, each unit of the control unit 111 can recognize which travel mode is currently set for the vehicle 1.

  The fuel consumption calculation unit 111d calculates the fuel consumption based on the rotation speed information supplied from the control device 131 to the control unit 111 and the remaining amount information. The fuel calculation unit 111d multiplies the rotation speed indicated by the rotation speed information sequentially supplied from the control device 131 by a preset travel distance for one rotation of the tire, and the vehicle for each first predetermined period. The travel distance of 1 is sequentially calculated, and the travel distance from a predetermined timing of the vehicle 1 (for example, when starting the motor of the vehicle 1 or the like) is monitored. Further, the fuel calculation unit 111d holds the remaining amount information sequentially supplied from the control device 131 in synchronization with the calculated travel distance in time series order. That is, the remaining amount information is held so that the remaining amount of the battery 7 at a certain travel distance can be known.

  Each time the vehicle 1 travels a predetermined travel distance interval (for example, 1 km, 10 km, or 20 km) in the same travel mode, the fuel calculation unit 111d has the same or closest timing as the start point and end point of the travel distance interval. The difference between the two remaining amounts respectively indicated by the corresponding two remaining amount information is taken. As a result, the energy consumption (integrated consumption capacity) when the vehicle 1 travels this distance is calculated. Then, the fuel calculation unit 111d divides the travel distance interval by the difference, calculates fuel consumption (Km / Ah) in the travel mode (see FIG. 2), and stores this fuel consumption (fuel consumption information) in the flash memory 112a. Record. The fuel consumption is calculated and recorded for each driving mode. The fuel consumption is calculated every time the vehicle 1 travels the predetermined travel distance interval, and is constantly updated to a new one. As a result, the remaining travel distance, which will be described later, is calculated based on the latest fuel consumption, and the accuracy of the remaining travel distance calculation is improved.

  Here, another concept of how to obtain the fuel consumption will be described with reference to FIG. As shown in FIG. 3, when the consumption (consumption capacity) at a certain time point is taken on the Y axis and the elapsed time is taken on the X axis, the cumulative consumption in the time interval when the vehicle 1 has traveled 1 km in the same travel mode. The amount C (the integrated value of the consumed capacity) is the difference in the remaining amount in the calculation formula for fuel consumption. Fuel consumption can be obtained by dividing the travel distance by the cumulative consumption C. As described above, the fuel calculation unit 111d may appropriately obtain the energy consumption (sequential difference in remaining amount) and obtain the fuel consumption from the consumption.

  When the travel mode is switched while the vehicle has not traveled for the predetermined travel distance interval, the fuel calculation unit 111d may monitor the travel distance again from the time of switching, or the travel mode may be changed. The amount of energy consumed up to the time of switching is calculated, and the total travel distance for one travel mode is calculated. When the predetermined travel distance interval is reached, the energy consumption in this travel mode is calculated. Thus, the fuel consumption may be calculated.

  The calculation of fuel consumption as described above may be performed by other appropriate methods. The fuel calculation unit 111d may calculate the fuel consumption by an appropriate method based on the information about the vehicle 1 such as the remaining amount information as described above. By calculating the fuel consumption, the latest fuel consumption is specified for each travel mode for the vehicle that actually traveled. Therefore, the actual fuel consumption in the travel mode is specified, and the accuracy of the remaining travel distance described later increases. Each fuel consumption may be a predetermined fixed value.

  In any of the above cases, it is assumed that the driving mode and the fuel efficiency that is a value that is appropriately updated by the above method or a fixed value are associated and recorded in the flash memory 112a. . (See data table in FIG. 4).

  The remaining amount acquisition unit 111a, the remaining travel distance specifying unit 111b, and the display control unit 111c perform display control processing. This display control process will be described with reference to the flowchart of FIG. This process starts when, for example, power supply from the battery 7 to the display control device 11 is started, and ends when power supply from the battery 7 to the display control device 11 is lost. .

  First, the remaining amount acquisition unit 111a acquires the latest remaining amount supplied from the control device 131 (step S101).

  When the remaining amount acquisition unit 111a acquires the remaining amount, the remaining travel distance specifying unit 111b refers to, for example, a data table recorded in the storage unit 112 (flash memory 112a) as shown in FIG. The fuel consumption is acquired for each driving mode. The remaining travel distance specifying unit 111b specifies the remaining travel distance in each travel mode by multiplying each acquired fuel efficiency by the acquired remaining amount and calculating the remaining travel distance for each travel mode (step S102). . This remaining travel distance is specified based on the remaining amount, and is a travelable distance in this travel mode when traveling in the travel mode set in the vehicle 1.

  When the remaining travel distance specifying unit 111b specifies the remaining travel distance, the display control unit 111c appropriately acquires other information (step S103). For example, the current time is obtained by referring to a time measuring unit (not shown), and is calculated from the current speed of the vehicle 1 (the time measured by the time measuring unit and the travel distance obtained from the number of rotations indicated by the rotation number information). ), The accumulated travel distance of the vehicle 1 up to the present (the integrated value of the travel distance obtained from the rotational speed indicated by the rotational speed information), the current remaining battery level (remaining capacity information), and the like.

  Thereafter, the display control unit 111c controls the display unit 114, the remaining travel distance for each travel mode acquired in step S102, the current time appropriately acquired in step S103, and the current vehicle 1 appropriately acquired in step S103. Information such as the speed, the accumulated travel distance of the vehicle 1 up to now, and the current remaining battery level is displayed on the display unit 114 (step S104), and then the remaining amount acquisition unit 111a performs step S101 again. By repeating such processing, the latest information is displayed on the display unit 114.

  An example of the screen displayed by the display unit 114 is shown in FIG. The display unit 114 appropriately displays the screen as shown in FIG. 6 by segment display, but the display unit 114 may display the screen for each pixel. In FIG. 6, various types of information are indicated by blackened portions.

  As shown in FIG. 6, the display unit 114 includes a screen 50 including a remaining battery capacity 52, a current time 51, a current speed 53 of the vehicle 1, and a cumulative travel distance 54 of the vehicle 1 up to now. Is displayed.

  Then, the display control unit 111c displays a list of remaining travel distances (travelable distances) for each travel mode in the display area 55 in the screen 50. In FIG. 6, the remaining traveling distance in the “ECO” mode is 132 km, the remaining traveling distance in the “NORMAL” mode is 100 km, and the remaining traveling distance in the “SPORTS” mode is 88 km. A black arrow in the arrow display area 56 indicates a travel mode currently set for the vehicle 1. That is, in the case of FIG. 6, the “NORMAL” mode is selected as the travel mode.

  As shown in FIG. 6, the display control unit 111 c displays the remaining travel distances of each of the plurality of travel modes in one screen 50, in particular, specifies the remaining travel distances of each of the plurality of travel modes for each travel mode. By displaying both of them in a list on one screen 50 in correspondence with information (here, name), the user viewing this screen can easily check the remaining travel distance in each travel mode. Moreover, it is easy to compare the remaining travel distances when the travel mode is set to the vehicle 1. Accordingly, this screen can be used as an index when the user selects the driving mode. In the above description, the remaining travel distances for all travel modes that can be set in the vehicle 1 are displayed on the display unit 114. However, the remaining travel distances for some of the travel modes are included in the remaining travel distances. May be displayed.

  The remaining travel distance may be expressed by numbers as shown in FIG. 6 (in this case, the user can easily grasp the remaining travel distance), but as a modification, for example, the remaining travel distance is shown in FIG. As described above, graph display (here, bar display) may be used. With such a graph display, the user can easily compare the remaining travel distance for each travel mode. As another modification, the remaining travel distance may be expressed by the number of icons indicating a predetermined distance, as shown in FIG. Thereby, the user can easily compare the remaining travel distances for each travel mode. The display control unit 111c may display the remaining travel distance on a screen as shown in FIG.

  Further, when displaying the remaining travel distance, the display control unit 111c may highlight the remaining travel distance having the longest distance and the travel mode having the remaining travel distance so as to be conspicuous. By this highlighting, the user can recognize which travel mode has the longest remaining travel distance. As highlighting, for example, the travel mode and / or the remaining travel distance is displayed with a thicker line than the others, the travel mode and / or the remaining travel distance is blinked, and the travel mode and / or the remaining travel distance is displayed in another color. The travel mode and / or the remaining travel distance are displayed larger than others, the travel mode and / or the remaining travel distance are displayed in a decorative manner, and the like. In FIGS. 7 and 8, decorative display is adopted as the highlight display, and dot image areas are displayed in the travel mode and the remaining travel distance.

  The remaining travel distance is displayed when, for example, the user performs an operation requesting this display on the operation unit 115 (that is, operation information of such an operation is supplied to the display control unit 111c or the like. Case). Thus, the remaining travel distance can be shown to the user at a timing desired by the user.

  Further, the remaining travel distance may be displayed when the vehicle 1 stops. In this case, for example, the information indicating that the vehicle has stopped is supplied from the control device 131 to the display control unit 111c, and the display control unit 111c displays the remaining travel distance when the information is supplied. Start. Further, this display may be ended when the vehicle 1 starts running, for example. In this way, the user can check the remaining travel distance while the vehicle 1 is stopped. Therefore, while the user is driving and driving the vehicle 1, the user is concerned about checking the remaining travel distance. Is prevented.

  The display of the remaining travel distance may be started when the remaining amount of the battery 7 becomes a predetermined value or less. In this case, for example, when the remaining amount acquisition unit 111a always acquires remaining amount information, monitors the remaining amount, and the remaining amount becomes a predetermined value or less. It is assumed that the display control unit 111c and the like start this display. Note that the display control unit 111c may appropriately terminate this display when the remaining amount of the battery 7 exceeds a predetermined value. Thus, the user can check the remaining travel distance when the remaining amount of the battery 7 is low, and thus can select a travel mode with a long remaining travel distance ("ECO mode" in FIGS. 6 to 8). In this case, since the user selects the “ECO” mode and performs the eco-driving operation, the user's awareness of energy saving can be improved.

  The remaining amount acquisition unit 111a, the fuel consumption calculation unit 111d, and the like may directly measure the remaining amount using the remaining amount meter 133. For example, the remaining amount acquisition unit 111a, the fuel consumption calculation unit 111d, and the like may measure the remaining amount by directly receiving a signal indicating the remaining amount from the remaining amount meter 133 and calculating the remaining amount from this signal. Even in such a case, the remaining amount acquisition unit 111a and the like acquire the remaining amount. In this way, acquiring the remaining amount is an expression appropriately including obtaining and measuring the remaining amount.

  In the above description, the display control device 11 is a display device including the display unit 114, but the display unit 114 may not be provided and the display unit 114 may be outside the display control device 11.

  The display control device 11 has been described as being mounted on an electric vehicle. However, as a modification, the display control device 11 may be used for an electric vehicle other than the electric vehicle. Examples of the electric vehicle include a vehicle such as an electric motorcycle, a ship, and an airplane. In addition, suppose that driving | running | working is an expression suitably including navigation or flight. Further, as a modification, the display control device is not used for an electric vehicle, but may be used for a vehicle that is moved by fuel such as gasoline. In this case, the remaining amount meter 133 is configured by a liquid level sensor or the like, and the remaining amount is specified from the position of the liquid level detected by the liquid level sensor. It should be noted that the remaining travel distance of each travel mode is important for an electric vehicle because there are fewer energy replenishment locations (places where charging is possible) than fuel vehicles. For this reason, a display control apparatus is more effective when used for an electric vehicle as in the above embodiment.

  Note that the above program may be one that causes a CPU to perform display control processing in cooperation with an OS (Operation System). In this case, the OS is also recorded in the ROM 112b. The program is recorded on a portable storage medium (for example, CD-ROM (Compact Disk Read Only Memory), DVD-ROM (Digital Versatile Disk Read Only Memory)) and supplied (installed) to the display control device 11. May be. The program may be supplied to the display control device 11 via a network. In these cases, the program is recorded in the flash memory 112a or the like.

  The ROM 112b, the flash memory, or a portable storage medium on which the program is recorded is a computer-readable storage medium that stores the program. The program may operate the display control device 11 in which at least part of the functions is realized by a dedicated circuit. That is, the display control device 11 may be anything that performs display control processing as a whole, and the control program only needs to operate such a display control device 11.
