[0001] The present invention relates to a display control device, a display control method and a display control program. Background Art

[0002] Japanese Unexamined Patent Application Publication No. 2010-41750 (JP 2010-41750A) discloses a technology for improving a driver's willingness to improve driving operation and awareness of fuel-saving driving. Summary of the invention

[0003] However, since the technology disclosed in JP 2010-41750A has a structure for displaying the degree of fuel-saving driving of the driver on a display unit of the vehicle, a manager who manages the driver cannot keep track of the frequency of energy-inefficient driving performed by the driver, thereby making it difficult to guide the driver to improve driving operations thereafter.

[0004] Therefore, an object of the present invention is to provide a display control device, a display control method and a display control program, which can make the driver understand driving with poor energy consumption efficiency when providing driving guidance.

[0005] According to the first aspect of the present disclosure, a display control device includes: an acquisition unit, which acquires vehicle information related to a vehicle state of a vehicle; a determination unit, which determines, based on the vehicle information acquired by the acquisition unit, whether the vehicle has been traveling in a state in which the vehicle has poor energy efficiency within a predetermined time from a predetermined driving operation of the vehicle; and a display control unit, which causes the display unit to display the number of times per unit time the vehicle has traveled in the state within a predetermined time from a predetermined driving operation, the travel being determined by the determination unit.

[0006] In the display control device according to the first aspect, an acquisition unit acquires vehicle information related to a vehicle state of a vehicle. In addition, based on the vehicle information acquired by the acquisition unit, a determination unit determines whether the vehicle has been traveling in a state where the vehicle has poor energy efficiency within a predetermined time from a predetermined driving operation of the vehicle. Then, the display control unit causes the display unit to display the number of times per unit time the vehicle has been traveling in the state within a predetermined time from a predetermined driving operation, the traveling being determined by the determination unit. Through this processing, in the display control device, the number of times the vehicle has been traveling in a state where the vehicle has poor energy efficiency per day is displayed on the display unit, whereby when providing driving guidance, the driver can be made aware of driving with poor energy efficiency based on these driving times.

[0007] In a display control device according to the first aspect, the vehicle is a hybrid electric vehicle equipped with multiple power sources of an engine and an electric motor; and based on vehicle information acquired by an acquisition unit, a determination unit determines whether the vehicle has been traveling in a state in which the engine has poor fuel consumption efficiency within a predetermined time from a predetermined driving operation of the vehicle.

[0008] In the display control device according to the above aspect, the vehicle is a hybrid electric vehicle equipped with a power source of an engine and an electric motor. Then, based on the vehicle information acquired by the acquisition unit, the determination unit determines whether the vehicle has been running in a state where the fuel consumption efficiency of the engine is poor within a predetermined time from a predetermined driving operation of the vehicle. Through this processing, in the display control device, the number of times the vehicle has been running in a state where the fuel consumption efficiency of the engine is poor per unit time is displayed on the display unit of the hybrid electric vehicle, thereby enabling the driver to understand driving with poor fuel consumption efficiency of the engine based on the number of times the vehicle has been running in this state when providing driving guidance.

[0009] In the display control device according to the above aspect, the predetermined driving operation is at least one of an accelerator operation at start-up, an accelerator operation during traveling, and a turn signal operation.

[0010] In the display control device according to the above aspect, the predetermined driving operation is at least one of an accelerator operation at the time of starting, an accelerator operation during driving, and a turn signal operation. With this configuration, in the display control device, the driver can be made aware of the number of times the driver has driven in an energy-poor manner within a predetermined time from at least one of the accelerator operation at the time of starting the vehicle, the accelerator operation during driving, and the turn signal operation.

[0011] According to the second aspect of the present disclosure, the display control method includes: acquiring vehicle information related to the vehicle state of the vehicle; determining, based on the acquired vehicle information, whether the vehicle has been traveling in a state in which the vehicle has poor energy efficiency within a predetermined time from a predetermined driving operation of the vehicle; and causing a display unit to display the determined number of times per unit time the vehicle has been driven in the said state within a predetermined time from a predetermined driving operation.

[0012] According to the third aspect of the present disclosure, the display control program enables the computer to: acquire vehicle information related to the vehicle state of the vehicle; determine, based on the acquired vehicle information, whether the vehicle has been traveling in a state in which the vehicle has poor energy efficiency within a predetermined time from a predetermined driving operation of the vehicle; and enable the display unit to display the determined number of times per unit time the vehicle has been driven in the said state within a predetermined time from a predetermined driving operation.

[0013] As described above, the display control device, the display control method, and the display control program according to the present invention can make the driver aware of driving with poor energy efficiency when providing driving guidance. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Hereinafter, the display control system 10 according to the present embodiment will be described.

[0026] The display control system 10 according to the present embodiment is a system that performs display control of a web application that can be viewed by both drivers of a business operator operating a vehicle, such as a taxi company and a transportation company, and a manager who manages the drivers.

[0027] Figure 1 is a diagram showing a schematic configuration of the display control system 10. Figure 1 As shown in , the display control system 10 includes a display control device 20, a driver terminal 40, and a vehicle 60. The display control device 20, the driver terminal 40, and the vehicle 60 are connected via a network N and can communicate with each other. The vehicle 60 connected to the network N is, for example, a car that travels while carrying a user.

[0028] The display control device 20 is a server computer owned by an operator who manages the vehicle 60. The driver terminal 40 is a mobile terminal owned by the driver of the vehicle 60. As an example, a portable personal computer (notebook PC), a smart phone, a tablet terminal, etc. are applied to the driver terminal 40. In the present embodiment, as an example, the driver terminal 40 is a smart phone.

[0029] The vehicle 60 is a split hybrid electric vehicle equipped with a plurality of power sources of an engine and an electric motor.

[0030] Next, the hardware configurations of the display control device 20 and the driver terminal 40 will be described. Figure 2 2 is a block diagram showing the hardware configuration of the display control device 20 and the driver terminal 40. Since the display control device 20 and the driver terminal 40 basically have a general-purpose computer configuration, the display control device 20 will be described as a representative.

[0031] like Figure 2 As shown in FIG. 1 , the display control device 20 includes a central processing unit (CPU) 21, a read only memory (ROM) 22, a random access memory (RAM) 23, a storage unit 24, an input unit 25, a display unit 26, and a communication unit 27. Each configuration is communicably connected to each other via a bus 28.

[0032] The CPU 21 is a central processing unit that executes various programs and controls various units. That is, the CPU 21 reads a program from the ROM 22 or the storage unit 24 and executes the program using the RAM 23 as a work area. The CPU 21 controls each of the above-mentioned configurations and performs various arithmetic processing according to the program recorded in the ROM 22 or the storage unit 24.

[0033] The ROM 22 stores various programs and various data. The RAM 23 temporarily stores programs or data as a work area.

[0034] The storage unit 24 is composed of a storage device such as a hard disk drive (HDD), a solid state drive (SSD) or a flash memory, and stores various programs and various data. In the present embodiment, the storage unit 24 stores at least a display control program 24A, which is used to perform a display process described later. In addition, the storage unit 24 stores the number of times the vehicle 60 travels in a specific state per day for each driver.

[0035] The input unit 25 includes a pointing device such as a mouse, a keyboard, a microphone, a camera, etc., and is used to perform various inputs.

[0036] The display unit 26 is, for example, a liquid crystal display, and displays various information. A touch panel may be employed as the display unit 26 , and the touch panel may be used as the input unit 25 .

[0037] The communication unit 27 is an interface for communicating with other devices. For communication, for example, a wired communication standard such as Ethernet (registered trademark) or Fiber Distributed Data Interface (FDDI) or a wireless communication standard such as the fourth generation (4G), the fifth generation (5G) or Wi-Fi (registered trademark) is used.

[0038] When executing the display control program 24A, the display control device 20 uses the hardware resources to perform processing based on the display control program 24A.

[0039] Next, the functional configuration of the display control device 20 will be described. Figure 3 : is a block diagram showing an example of the functional configuration of the display control device 20 according to the present embodiment.

[0040] like Figure 3 As shown, the CPU 21 of the display control device 20 includes an acquisition unit 21A, a determination unit 21B, and a display control unit 21C as functional configurations. Each functional configuration is realized when the CPU 21 reads and executes a display control program 24A stored in the storage unit 24.

[0041] The acquisition unit 21A acquires vehicle information related to the vehicle state of the vehicle 60. Specifically, the acquisition unit 21A acquires the steering angle, acceleration, vehicle speed, and turn signal operation of the vehicle 60 as vehicle information, which are respectively detected by a steering angle sensor 71, an acceleration sensor 72, a vehicle speed sensor 73, and a turn signal switch 74 (described later) included in the vehicle 60. In addition, the acquisition unit 21A acquires the engine speed, engine torque, fuel consumption, and accelerator operation of the vehicle 60 detected by an electronic control unit (ECU) 70C (described later) included in the vehicle 60 as vehicle information.

[0042] Based on the vehicle information acquired by the acquisition unit 21A, the determination unit 21B determines whether the vehicle 60 has been traveling in a specific state in which the energy consumption efficiency of the vehicle 60 is poor within a predetermined time from a predetermined driving operation of the vehicle 60. The specific state is an example of a "state". In the present embodiment, as an example, the above-mentioned predetermined time is set to "one second". The energy consumption efficiency is the energy consumption efficiency required for the vehicle to travel, including, for example, fuel consumption efficiency and electricity cost efficiency. In the present embodiment, based on the vehicle information, the determination unit 21B determines whether the vehicle 60 has been traveling in a specific state in which the fuel consumption efficiency of the engine is poor within a predetermined time from a predetermined driving operation of the vehicle 60 as a hybrid electric vehicle.

[0043] Here, in the present embodiment, the above-mentioned predetermined driving operation includes an accelerator operation at the time of starting (hereinafter referred to as "starting operation"), an accelerator operation during traveling (hereinafter referred to as "acceleration operation"), and a turn signal operation.

[0044] As an example, when the accelerator operation is detected by the ECU 70C while the vehicle 60 is stopped, the determination unit 21B determines that the starting operation has been performed. In addition, when the acceleration sensor 72 detects a predetermined acceleration after the accelerator operation is detected by the ECU 70C while the vehicle 60 is traveling, the determination unit 21B determines that the acceleration operation has been performed. In addition, when the operation of the turn signal switch 74 is detected by the ECU 70D, the determination unit 21B determines that the turn signal operation has been performed.

[0045] Then, as an example, when the relationship between the engine speed and engine torque of the vehicle 60 detected by ECU 70C within a predetermined time from any of the above-mentioned predetermined driving operations corresponds to a specific relationship defined for each vehicle, the determination unit 21B determines that the vehicle 60 has been traveling in a specific state.

[0046] The display control unit 21C causes the display unit 26 to display the number of times the vehicle is driven in a specific state within a predetermined time from a predetermined driving operation per day (as a unit time) determined by the determination unit 21B. A specific example of the number of times the vehicle is driven in a specific state displayed on the display unit 26 will be described later.

The CPU 61, the ROM 62, the RAM 63, the storage unit 64, the vehicle-mounted communication I / F 65, the input and output I / F 66, and the wireless communication I / F 67 are connected to each other so as to be able to communicate with each other via an internal bus 68.

[0050] The CPU 61 is a central processing unit that executes various programs and controls various units. That is, the CPU 61 reads a program from the ROM 62 or the storage unit 64 and executes the program using the RAM 63 as a work area.

[0053] The vehicle-mounted communication I / F 65 is an interface for connecting to the ECU 70 . For this interface, a communication standard based on a controller area network (CAN) protocol is used. The vehicle-mounted communication I / F 65 is connected to the external bus 81 .

[0054] The ECU 70 is provided for the corresponding functions of the vehicle 60, and in the present embodiment, ECU 70A, ECU 70B, ECU 70C, and ECU 70D are provided.

In addition, ECU70D is illustrated as a steering ECU, and the turn signal switch 74 is connected to ECU70D. The turn signal switch 74 is set on the steering column for operating the turn signal. ECU70D detects the driver's operation of the turn signal switch 74 as a turn signal operation. The turn signal operation detected by ECU70D is stored in the storage unit 64 and transmitted to the display control device 20 as vehicle information.

[0056] The steering angle sensor 71 is a sensor for detecting a steering angle of a steering wheel. The steering angle detected by the steering angle sensor 71 is stored in the storage unit 64 and transmitted to the display control device 20 as vehicle information.

[0057] The acceleration sensor 72 is a sensor for detecting acceleration acting on the vehicle 60. The acceleration sensor 72 is, for example, a three-axis acceleration sensor that detects acceleration applied in the vehicle front-rear direction as the X-axis direction, the vehicle width direction as the Y-axis direction, and the vehicle height direction as the Z-axis direction. The acceleration detected by the acceleration sensor 72 is stored in the storage unit 64 and transmitted to the display control device 20 as vehicle information.

[0058] The vehicle speed sensor 73 is a sensor for detecting the vehicle speed of the vehicle 60. The vehicle speed sensor 73 is, for example, a sensor provided on a wheel. The vehicle speed detected by the vehicle speed sensor 73 is stored in the storage unit 64 and transmitted to the display control device 20 as vehicle information.

[0059] The input and output I / F 66 is an interface for communicating with a microphone 75 , a camera 76 , an input switch 77 , a monitor 78 , a speaker 79 , and a GPS device 80 mounted on the vehicle 60 .

[0060] The microphone 75 is a device provided on a front pillar, a dashboard, or the like of the vehicle 60, and collects sounds made by a driver of the vehicle 60. The microphone 75 may be provided in a camera 76 which will be described later.

[0061] As an example, the camera 76 is configured to include a charge coupled device (CCD) image sensor. The camera 76 is, for example, disposed at the front of the vehicle 60 and captures an image in front of the vehicle 60. The image captured by the camera 76 is used, for example, to identify the inter-vehicle distance to a preceding vehicle, a lane, a traffic light, etc. traveling in front of the vehicle 60. The image captured by the camera 76 is stored in the storage unit 64 and transmitted to the display control device 20. Note that the camera 76 may be configured as an imaging device for other purposes, such as a driving recorder. In addition, the camera 76 may be connected to the vehicle-mounted device 15 via the ECU 70 (e.g., a camera ECU).

[0062] The input switch 77 is provided on the instrument panel, the center console, the steering wheel, etc., and is a switch for input operation by the driver's finger. As the input switch 77, for example, a button-type numeric keypad, a touch panel, etc. can be adopted.

[0065] The GPS device 80 is a device that measures the current position of the vehicle 60. The GPS device 80 includes an antenna (not shown) that receives signals from GPS satellites. Note that the GPS device 80 may be connected to the vehicle-mounted device 15 via a car navigation system connected to the ECU 70 (eg, a multimedia ECU).

[0066] The wireless communication I / F 67 is a wireless communication module for communicating with the display control device 20. For the wireless communication module, for example, communication standards such as 5G, Long Term Evolution (LTE), and Wi-Fi (registered trademark) are used. The wireless communication I / F 67 is connected to the network N.

[0067] Figure 5 2 is a flowchart showing the flow of a display process performed by the display control device 20, which displays the number of times of driving in a specific state per day on the display unit 26. This display process is performed when the CPU 21 reads the display control program 24A from the storage unit 24, expands the display control program 24A into the RAM 23, and executes the program.

[0068] exist Figure 5In step S10 shown, the CPU 21 acquires vehicle information from the vehicle 60. Then, the process proceeds to step S11. In the present embodiment, as an example, the vehicle information is transmitted from the vehicle 60 to the display control device 20 every hour.

[0069] In step S11, CPU21 determines whether the vehicle has been running in a specific state based on the vehicle information obtained in step S10. When CPU21 determines that the vehicle has been running in a specific state (step S11: Yes), the process proceeds to step S12. On the other hand, when CPU21 determines that the vehicle is not running in a specific state (step S11: No), the process proceeds to step S13. As an example, CPU21 determines that the relationship between the engine speed and the engine torque of the vehicle 60 within a predetermined time from any predetermined driving operation of the starting operation, the acceleration operation, and the turn signal operation corresponds to a specific relationship defined for each vehicle. When the relationship corresponds to a specific relationship, CPU21 determines that the vehicle 60 "has been running in a specific state".

[0070] In step S12, the CPU 21 adds the number of times of traveling in a specific state determined in step S11 to the number of times of traveling in a specific state per day corresponding to the driver of the vehicle 60 stored in the storage unit 24. Then, the process proceeds to step S13.

[0071] In step S13, CPU 21 determines whether one day as a unit time has passed since the start of the display process. When CPU 21 determines that one day has passed (step S13: Yes), the process proceeds to step S14. On the other hand, when CPU 21 determines that one day has not passed (step S13: No), the process returns to step S10.

[0072] In step S14, the CPU 21 causes the display unit 26 to display the number of times the vehicle 60 travels in a specific state every day corresponding to the driver of the vehicle 60. Then, the process ends.

[0073] Next, in Figure 5 In step S14 shown in FIG. 1 , a display example of the web application displayed on the display unit 26 of the display control device 20 will be described.

[0074] Figure 6 is a first display example of a web application displayed on the display unit 26 of the display control device 20.

Specifically, the result display unit 85 shows that the total number of times the vehicle drove in a specific state within a predetermined time after the start operation on April 30, 2021 was: driver A "100 times", driver B "80 times", and driver C "50 times".

[0083] The screen switching button 89 is a button for switching the display content of the result display unit 85 to a screen displaying the total number of times of traveling in a specific state per day.

[0086] Figure 8 The result display unit 85 shown shows the number of times the drivers managed by the manager drive in a specific state within a predetermined time after the acceleration operation every day. Specifically, the result display unit 85 shows that the total number of times the vehicle drove in a specific state within a predetermined time after the acceleration operation on April 30, 2021 was: driver A "60 times", driver B "40 times", and driver C "30 times".

[0087] Fig. 9 is a fourth display example of the web application displayed on the display unit 26 of the display control device 20 . Fig. 9 The display example shown in FIG. Figure 8 The display example shown is a state after the screen switching button 88 is operated simultaneously.

[0088] exist Fig. 9 In the illustrated display example, a result display unit 85 , a screen switching button 86 , a screen switching button 87 , and a screen switching button 89 are illustrated.

[0089] Fig. 9 The result display unit 85 shown shows the number of times the drivers managed by the manager drove in a specific state within a predetermined time after the turn signal operation every day. Specifically, the result display unit 85 shows that the total number of times the driver A drove in a specific state within a predetermined time after the turn signal operation on April 30, 2021 was: driver A "40 times", driver B "30 times", and driver C "20 times".

[0090] Here, among the drivers of companies operating vehicles such as taxi companies and transport companies, there are drivers who drive in an energy-efficient manner and drivers who drive in an energy-inefficient manner. In this case, the manager who manages the drivers usually wants all drivers to perform energy-saving driving.

[0091] As a result of verification by the applicant, it has been pointed out that in a hybrid electric vehicle, a driver who drives the engine in a manner with poor fuel consumption efficiency drives the vehicle in a specific state more often within a predetermined time after a predetermined driving operation than a driver who drives the engine in a manner with good fuel consumption efficiency.

[0092] As described above, in the present embodiment, the CPU 21 acquires the vehicle information of the vehicle 60. In addition, the CPU 21 determines whether the vehicle 60 has been traveling in a specific state within a predetermined time from a predetermined driving operation of the vehicle 60 based on the acquired vehicle information. Then, the CPU 21 causes the display unit 26 to display the determined number of times the vehicle has been traveling in a specific state within a predetermined time from a predetermined driving operation every day. Through this processing, in the present embodiment, the number of times the vehicle has been traveling in a specific state every day is displayed on the display unit 26, whereby when providing driving guidance, the driver can be made aware of driving with poor energy consumption efficiency based on the number of times the vehicle has been traveling in a specific state. As an example, in the present embodiment, the manager confirms the number of times the vehicle has been traveling in a specific state for each driver displayed on the display unit 26, and instructs the driver who is driving in a manner with poor energy consumption efficiency to reduce the number of times the vehicle has been traveling in a specific state, whereby the driver can be made aware that the driver is driving in a manner with poor energy consumption efficiency.
