DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0010] <Outline of saddle-type vehicle> 1 is a side view of a saddle-type vehicle (hereinafter simply referred to as a vehicle) 100 according to one embodiment of the present invention. The vehicle 100 is a motorcycle equipped with one front wheel FW and one rear wheel RW, and is driven by an internal combustion engine.

[0011] The vehicle 100 includes a body frame 101 that forms the skeleton of the vehicle. A front wheel steering unit 102 is supported at the front end of the body frame 101, and a swing arm 115 is supported at the rear end so as to be freely swingable. The front wheel steering unit 102 includes a pair of left and right front forks 103 that support the front wheel FW, and a steering handlebar 104 attached to the upper part of the pair of front forks 103. A right grip 105 of the steering handlebar 104 is an accelerator grip with which the rider can instruct the acceleration of the vehicle 100. A brake lever 106 that receives the rider's braking operation on the front wheel FW is provided adjacent to the right grip 105 so as to be freely rotatable.

[0012] A display unit 9 is attached to the vehicle body frame via a stay (not shown) in front of the steering handle 104. 101 The display unit 9 is an electronic image display panel that displays various information such as the vehicle speed to a rider, and is, for example, a liquid crystal display panel.

[0013] The swing arm 115 has a front end supported by the body frame 101 so as to be freely swingable, and a rear wheel RW is supported at its rear end. An internal combustion engine 107 and a transmission 108 are supported by the body frame 101 in a region between the front wheel FW and the rear wheel RW. In this embodiment, the internal combustion engine 107 is an in-line four-cylinder four-stroke engine. The output of the internal combustion engine 107 is transmitted to the rear wheel RW via the transmission 108 and a chain transmission mechanism (not shown). A fuel tank 109 is disposed above the internal combustion engine 107, and a seat 110 on which a rider sits is disposed behind the fuel tank 109. The fuel tank 109 contains fuel (gasoline in this embodiment) for the internal combustion engine 107 as the driving energy for the vehicle 100.

[0014] The braking device 111 is a device that applies a braking force to the front wheel FW, and in this embodiment, is a disc brake. The braking device 111 includes a brake rotor 112 that rotates coaxially with the front wheel FW, and a brake caliper 113 that is supported by the front fork 103 and that sandwiches the brake rotor 112 with brake pads (not shown) to resist the rotation of the brake rotor 112 with friction. The clamping force of the brake caliper 113 is generated according to the amount of operation of the brake lever 106, that is, a braking force is generated on the front wheel FW according to the amount of operation of the brake lever 106.

[0015] The braking device 116 is a device that applies a braking force to the rear wheel RW, and in this embodiment, is a disc brake. The braking device 116 includes a brake rotor 117 that rotates coaxially with the rear wheel RW, and a brake caliper 118 that is supported by a swing arm 115 and that sandwiches the brake rotor 117 to resist its rotation. The clamping force of the brake caliper 118 is generated according to the amount of operation of a brake pedal 119, that is, a braking force is generated on the rear wheel RW according to the amount of operation of the brake pedal 119.

[0016] <Control circuit> 2A is a block diagram of a display device 1 equipped with a display unit 9. The display device 1 is equipped with a control circuit 10 that controls the display of the display unit 9. The control circuit 10 includes a processing unit 11, a storage unit 12, and an I / F (interface) unit 13 that relays the transmission and reception of signals between an external device and the processing unit 11. The processing unit 11 is a processor represented by a CPU, and controls the display of the display unit 9 by executing a program stored in the storage unit 12. The storage unit 12 is a semiconductor memory such as a ROM, a RAM, etc., and stores various data in addition to the program executed by the processing unit 11.

[0017] The detection results of the various sensors 2 to 7 are input to the interface unit 13 via a signal processing circuit (not shown), and the processing unit 11 updates the display content of the display unit 9 based on the input detection results. The remaining fuel sensor 2 detects the remaining amount of fuel in the fuel tank 109. The remaining fuel sensor 2 includes, for example, a float that floats on the fuel, and detects the remaining amount by identifying the height of the fuel level according to the position of the float.

[0018] The water temperature sensor 3 detects the temperature of the cooling water for the internal combustion engine 107. The vehicle speed sensor 4 is a sensor that detects the traveling speed of the vehicle 100, and detects, for example, the rotation amount of the front wheels FW. The air temperature sensor 5 detects the outside air temperature around the vehicle 100. The engine rotation speed sensor 6 detects the rotation speed of the internal combustion engine 107. The neutral sensor 7 detects whether the gear position of the transmission 108 is neutral or not.

[0019] The interface unit 13 also receives information from a route guidance device 8. The route guidance device 8 is a device that performs route guidance to a destination set by the occupant, and includes a GNSS sensor 81 that detects the current position of the vehicle 100, a map database 82, and the like. In this embodiment, the route guidance device 8 is provided in the vehicle 100. However, for example, cell phone A mobile terminal such as a smartphone that supports a navigation system can also be used as the route guidance device 8. In this case, the display device 1 includes a short-range wireless communication device that performs wireless communication with the mobile terminal, and can obtain information from the mobile terminal via the short-range wireless communication device.

[0020] 2B shows an example of the display of the display unit 9. The display unit 9 has a shift indicator 90 and an information display screen 91. The shift indicator 90 displays the gear position of the transmission 108. The processing unit 11 identifies the gear position based on the detection results of the vehicle speed sensor 4 and the engine speed sensor 6 and the detection result of the neutral sensor 7, and displays it on the shift indicator 90.

[0021] Various information is displayed on each part (display area) of the information display screen 91. In the illustrated example, vehicle speed information 92, mileage information 93, temperature information 94, remaining amount information 95, and engine speed information 96 are displayed. The vehicle speed information 92 is information on the vehicle speed calculated based on the detection result of the vehicle speed sensor 4. The mileage information 93 is information on the total mileage of the vehicle 100 obtained by accumulating the distance calculated based on the detection result of the vehicle speed sensor 4 using a part of the storage area of ​​the storage unit 12. The temperature information 94 is information on the temperature based on the detection result of the temperature sensor 5. The remaining amount information 95 is information indicating the remaining amount of fuel based on the detection result of the remaining fuel sensor 2. In the case of this embodiment, the remaining amount information 95 displays the remaining amount of fuel at multiple levels, and specifically, a level meter in which the remaining amount is expressed by the number of level indications M is displayed. The engine speed information 96 is information based on the detection result of the engine speed sensor 6.

[0022] <Control example> An example of control executed by the processing unit 11 will be described. In this embodiment, remaining amount information 95 is displayed on the information display screen 91. However, when the occupant is aware of the remaining amount of fuel, such as after refueling, there is little need to display the remaining amount information 95. Since the display layout and display contents of the information display screen 91 can be changed, when there is little need to display the remaining amount information 95, the display area can be used as a display area for other information, making it possible to provide the occupant with more useful information and also making it easier for the occupant to quickly find the information they need. Therefore, in this embodiment, the display / non-display of the remaining amount information 95 is switched under a predetermined condition.

[0023] 3A is a flowchart relating to the remaining fuel management process executed by the processing unit 11. When the main power supply of the vehicle 100 is turned off (in this embodiment, the IG (ignition) is turned off), the processing unit 11 acquires the detection result of the remaining fuel sensor 2 in S1. In S2, the detection result acquired in S1 is stored in the storage unit 12. This ends the process.

[0024] 3B is a flowchart related to the display control process executed by the processing unit 11, and in particular, the process related to switching between displaying and hiding the remaining amount information 95. The process example of FIG. 3B is performed when the vehicle 100 is started (in this embodiment, when the main power source is turned on (IG (ignition) is turned on)). ) is executed.

[0025] In S11, the detection result of the remaining fuel sensor 2 is obtained. In S12, based on the detection result obtained in S11, remaining amount information 95 is displayed on the information display screen 91 for a predetermined time (for example, several tens of seconds to several minutes). By displaying remaining amount information 95 every time the vehicle 100 is started, the occupant can be made more reliably aware of the remaining amount of fuel.

[0026] In S13, the remaining amount of fuel stored in S2 is compared with the remaining amount of fuel acquired in S11 to determine whether the remaining amount has increased. For example, the remaining amount increases when the occupant refuels. If it is determined that the remaining amount has increased, the process proceeds to S14, and if the remaining amount has not increased, the process proceeds to S16.

[0027] In S14, it is determined whether the remaining amount of fuel is equal to or greater than a threshold value TH1. For example, if the remaining amount of fuel when the fuel tank 109 is full is 100%, the threshold value TH1 is set to a value between 85% and 95%, for example, 90%. If the remaining amount of fuel is equal to or greater than the threshold value TH1, the process proceeds to S15, and if it is less than the threshold value TH1, the process proceeds to S16. In S16, the display of the remaining amount information 95 continues.

[0028] In S15, the display of remaining amount information 95 is switched to hidden on the information display screen 91. Fig. 4A shows an example of the display of the information display screen 91 after switching. Comparing the example of Fig. 2B with the example of Fig. 4A, the remaining amount information 95 that was displayed in the left portion of the information display screen 91 is no longer displayed. As a result of other information (vehicle speed information 92, etc.) standing out, it becomes easier for the occupant to quickly find the information he or she needs.

[0029] Other information may be displayed in the area where remaining amount information 95 was displayed. As a form of displaying other information, the display of already displayed information may be enlarged. For example, the display area of ​​vehicle speed information 92 may be expanded to include the area where remaining amount information 95 was displayed. This makes it easier to see the numbers indicating vehicle speed. As a form of displaying other information, other information that is not already displayed may be displayed. FIG. 4B shows an example. Water temperature information 97 is displayed in the area where remaining amount information 95 was displayed. Water temperature information 97 is information indicating the water temperature of internal combustion engine 107 based on the detection result of water temperature sensor 3. In this way, more useful information can be provided to the occupants.

[0030] The remaining amount information 95 is switched to non-display on the condition that the remaining amount of fuel increases and is equal to or greater than the threshold value TH1. After refueling, if there is sufficient remaining amount, it is considered that the need for the remaining amount information 95 is low for the occupants.

[0031] If the remaining amount information 95 remains hidden, it becomes difficult for the occupant to judge the cruising distance thereafter. Next, the process of the processing unit 11 when the remaining amount information 95 is switched from a hidden state to a displayed state will be described. Fig. 5 is a flowchart of this process, which is periodically and repeatedly executed while the remaining amount information 95 is hidden.

[0032] In S21, the travel distance of the vehicle 100 while the remaining amount information 95 is not displayed is accumulated. The travel distance can be accumulated based on the detection result of the vehicle speed sensor 4. In S22, it is determined whether the travel distance accumulated in S21 is equal to or greater than a threshold value TH2 (e.g., 10 km). If the travel distance is equal to or greater than the threshold value TH2, the process proceeds to S23, and if it is less than the threshold value, the process proceeds to S26.

[0033] In S23, the detection result of the remaining fuel sensor 2 is acquired. In S24, it is determined whether the remaining amount of fuel acquired in S23 is less than a threshold value TH3. For example, if the remaining amount of fuel when the fuel tank 109 is full is 100%, the threshold value TH3 is set to a value between 75% and 85%, for example, 80%. The threshold value TH3 may be the same as or different from the threshold value TH1. If the remaining amount of fuel is less than the threshold value TH3, the process proceeds to S25, and if it is equal to or greater than the threshold value TH3, the process proceeds to S26. In S26, the remaining amount information 95 continues to be hidden.

[0034] In S25, the display of the remaining amount information 95 is resumed. As shown in Fig. 2B, the remaining amount information 95 is displayed in a part of the information display screen 91. The occupant can recognize the remaining amount of fuel.

[0035] The condition for resuming the display of the remaining fuel amount information 95 is that the remaining amount of fuel falls below the threshold value TH3. When a certain amount of fuel has been consumed, it is considered that the crew will be concerned about the remaining amount of fuel, and the need for the remaining fuel amount information 95 is considered to be high.

[0036] Next, another example of processing by the processing unit 11 when the remaining amount information 95 is switched from a hidden state to a displayed state will be described. FIG. 6 is a flowchart of this processing, which is periodically and repeatedly executed while the remaining amount information 95 is hidden. In the example of FIG. 6, during route guidance by the route guidance device 8, Remaining The display of the information 95 is resumed under a predetermined condition, and the fuel is prevented from running out on the way to the destination when the vehicle 100 travels thereto.

[0037] In S31, it is determined whether or not route guidance is being performed by the route guidance device 8. Whether or not route guidance is being performed can be determined, for example, from information from the route guidance device 8. If route guidance is being performed, the process proceeds to S32, and if route guidance is not being performed, the process proceeds to S35.

[0038] S32 instructs the route guiding device 8 to provide distance information between the current position of the vehicle 100 and the nearest fuel supply station (such as a gas station), and acquires the distance information from the route guiding device 8. S33 determines whether the distance indicated by the distance information acquired in S32 is equal to or greater than a threshold value TH4. The threshold value TH4 is, for example, a distance within a range of 50 km to 150 km, e.g., 100 km. If the supply station is far from the current position, it is highly necessary to make the occupants aware of the cruising distance.

[0039] If the distance is equal to or greater than the threshold TH4, the process proceeds to S34, and if the distance is less than the threshold TH4, the process proceeds to S35. In S35, the remaining amount information 95 continues to be hidden.

[0040] In S34, the display of the remaining amount information 95 is resumed. As illustrated in Fig. 2B, the remaining amount information 95 is displayed in a part of the information display screen 91. The occupant can recognize the remaining amount of fuel and can drive the vehicle 100 while taking into account the refueling schedule to the destination.

[0041] <Other embodiments> In the above embodiment, the vehicle 100 using the internal combustion engine 107 as a drive source has been exemplified, but the vehicle may be an electric vehicle using a motor as a drive source. In this case, the remaining energy of the vehicle is the remaining amount of the battery that supplies power to the motor, and the remaining amount of the battery may be, for example, the state of charge (SOC). The remaining amount of the battery may be detected by a voltage sensor or a current sensor. Furthermore, the vehicle may be a vehicle other than a two-wheeled vehicle, such as a four-wheeled vehicle.
