[Figure 5] FIG. 5 is an explanatory diagram of an embodiment in which upper body target operation recommendation information and lower body target operation recommendation information are alternately displayed. DETAILED DESCRIPTION OF THE INVENTION

[0016] [1. How to use the mobility support] A usage mode of a mobility support device 1 of the present disclosure will be described with reference to Fig. 1. The mobility support device 1 is mounted on a vehicle 100. The vehicle 100 is equipped with a communication unit 2, an ECU (Electronic Control Unit) 3, a driver monitor camera 30, a speaker 31, a display 32, a steering wheel 33, an accelerator pedal 34, and a brake pedal 35.

[0017] The vehicle 100 corresponds to the mobile body of the present disclosure. The steering wheel 33, accelerator pedal 34, and brake pedal 35 correspond to the driving operation unit of the present disclosure. Hereinafter, the steering wheel 33, accelerator pedal 34, and brake pedal 35 will also be collectively referred to as the driving operation unit. The speaker 31 and the display 32 correspond to the information output device of the present disclosure. The communication unit 2 performs wireless communication, for example, via Bluetooth (registered trademark), with a communication terminal 50 used by the driver D. The communication terminal 50 is a smartphone, tablet terminal, mobile phone, etc.

[0018] The ECU 3 switches between a manual driving mode in which the driving (movement control) of the vehicle 100 is performed in response to the operation of the driving operation unit by the driver D, and an automatic driving mode in which the driving of the vehicle 100 is automatically controlled by recognizing the situation around the vehicle 100 using a camera and radar (not shown) provided in the vehicle 100 without the operation of the driving operation unit by the driver D. The steering wheel 33 is of a steer-by-wire type, in which it is mechanically separated from the steering mechanism and its operation status is detected electrically. Similarly, the accelerator pedal 34 and the brake pedal 35 are also of a drive-by-wire type, in which it is mechanically separated from the mechanical parts to be operated and its operation status is detected electrically.

[0019] In the autonomous driving mode, the driver D does not need to operate the driving operation unit, and the driving burden is reduced, so it is expected that there will be more opportunities to travel for long periods of time. Furthermore, by continuing to sit in the driver's seat 5 for long periods of time, the driver D may become inactive and develop a subject disorder.

[0020] Therefore, while the vehicle 100 is traveling in the autonomous driving mode, the mobility support device 1 performs a process to provide an environment in which the driver D can spend his / her travel time comfortably by utilizing the steering wheel 33, accelerator pedal 34, and brake pedal 35, which are not used in the autonomous driving mode and are mechanically separated from the objects to be operated, and therefore can be diverted to uses other than driving operations, thereby relieving the driver D of the lack of exercise.

[0021] Specifically, the mobility support device 1 displays on the display 32 an operation recommendation image (corresponding to the operation recommendation information of the present disclosure) that prompts the driver D to operate any one of the steering wheel 33, accelerator pedal 34, and brake pedal 35. Upon viewing the operation recommendation image, the driver D operates the steering wheel 33, accelerator pedal 34, or brake pedal 35 in accordance with the operation content specified by the operation recommendation image. This makes it possible to provide the driver D with an environment in which he or she can comfortably spend the period of travel in autonomous driving mode while preventing a lack of exercise.

[0022] [2. Configuration of mobility support device] The configuration of the mobility support device 1 will be described with reference to Figures 2 and 3. With reference to Figure 2, the mobility support device 1 is a control unit including a processor 10, a memory 20, etc. The mobility support device 1 may be a dedicated device, or may be configured as part of the functions of a control device such as an ECU 3 provided in the vehicle 100. The mobility support device 1 is connected to a communication unit 2, the ECU 3, a driver monitor camera 30, a speaker 31, a display 32, a steering sensor 33a, an accelerator pedal sensor 34a, and a brake pedal sensor 35a.

[0023] The driver monitor camera 30 captures an image of the vicinity of the driver's seat 5 (see FIG. 1 ), including the driver D, and inputs the captured image to the mobility support device 1. The steering sensor 33a detects the steering angle of the steering wheel 33 and inputs a detection signal to the mobility support device 1. The accelerator pedal sensor 34a detects the amount of depression of the accelerator pedal 34 and inputs a detection signal to the mobility support device 1. The brake pedal sensor 35a detects the amount of depression of the brake pedal 35 and inputs a detection signal to the mobility support device 1.

[0024] The steering wheel 33 is an electric power steering system and is equipped with an actuator 33b that changes the level of input required to operate the steering wheel 33. The accelerator pedal 34 and the brake pedal 35 are also equipped with actuators 34b and 35b, respectively, that change the level of input required to operate them.

[0025] The processor 10 reads and executes a program 21 for controlling the mobility support device 1 stored in the memory 20, thereby functioning as an operation recommendation unit 11 and an operation situation recognition unit 12. The processing executed by the operation recommendation unit 11 corresponds to the operation recommendation step in the mobility support method of the present disclosure.

[0026] Operation recommendation unit 11 recognizes whether vehicle 100 is running in manual driving mode or automatic driving mode through communication with ECU 3. When vehicle 100 is running in automatic driving mode, operation recommendation image 200 is displayed on display 32 to prompt the driver to operate the driving operation unit, as shown in FIG.

[0027] The operation recommendation image 200 displays an image portion 201 that encourages the driver to turn the steering wheel (steering wheel) 33 to the right for 10 seconds, and an image portion 202 that encourages the driver to operate (depress) a pedal (accelerator pedal 34 or brake pedal 35). The driver D visually recognizes the operation recommendation image 200, and operates the steering wheel 33 to the right as shown in A1 in accordance with the display of the image portion 201, and depresses a pedal (accelerator pedal 34 is exemplified in FIG. 3 ) as shown in A2 in accordance with the display of the image portion 202. The operation recommendation unit 11 sets the strength of the operation of the driving operation unit to increase as the duration of driving in the autonomous driving mode increases.

[0028] The operation recommendation unit 11 changes the strength of the operation of the driving operation unit by the following method 1 or method 2. Method 1: Increasing or decreasing the number of times the driver operates the driving control unit. By increasing the number of times the driver operates the driving control unit, which is prompted by the operation recommendation image, the strength of the operation of the driving control unit is increased. Method 2: The load applied by the actuators 33b, 34b, and 35b is increased or decreased to increase or decrease the input level required to operate the driving operation unit.

[0029] The operation status recognition unit 12 recognizes the operation status of the steering wheel 33 based on a detection signal from the steering sensor 33a, recognizes the operation status of the accelerator pedal 34 based on a detection signal from the accelerator pedal sensor 34a, and recognizes the operation status of the brake pedal 35 based on a detection signal from the brake pedal sensor 35a. The operation recommendation unit 11 executes processing to change the display mode of the operation recommendation image according to the operation statuses of the steering wheel 33, accelerator pedal 34, and brake pedal 35 recognized by the operation status recognition unit 12. Details of this processing will be described later.

[0030] [3. Recommended Operation] The procedure of the operation recommendation process executed by the travel support device 1 will be described according to the flowchart shown in Fig. 4. While the vehicle 100 is traveling in the autonomous driving mode, the travel support device 1 repeatedly executes the operation recommendation process according to the flowchart shown in Fig. 4.

[0031] In step S1 of Fig. 4, operation recommendation unit 11 advances the process to step S2 when the recommended driving timing arrives. The recommended driving timing is set, for example, when vehicle 100 has been traveling in autonomous driving mode for several tens of minutes or more. In step S2, operation recommendation unit 11 sets the operation intensity of the driving operation units urged by the operation recommendation image to be greater the longer the driving continues in autonomous driving mode.

[0032] In the next step S3, operation recommendation unit 11 displays an operation recommendation image on display 32, encouraging the driver to operate the driving operation units according to the set operation strength. In the next step S4, operation recommendation unit 11 starts an operation confirmation timer to confirm whether or not the driver D has operated the driving operation units. In the next step S5, operation status recognition unit 12 recognizes the operation status of the driving operation units.

[0033] In the next step S6, the operation recommendation unit 11 determines whether the operation of the operation content prompted by the operation recommendation image has been recognized by the operation situation recognition unit 12. If the operation of the operation content prompted by the operation recommendation image has been recognized, the operation recommendation unit 11 proceeds to step S7, and if the operation of the operation content prompted by the operation recommendation image has not been recognized, the operation recommendation unit 11 proceeds to step S10. In step S7, the operation recommendation unit 11 ends display of the operation recommendation image on the display 32.

[0034] In step S10, operation recommendation unit 11 determines whether the operation confirmation timer has timed out, and if the operation confirmation timer has timed out, proceeds to step S11, whereas if the operation confirmation timer has not timed out, proceeds to step S11. In step S11, operation recommendation unit 11 lowers the setting of the operation strength of the driving operation units that driver D is prompted to operate using the operation recommendation image, and proceeds to step S3. As a result, in step S3, operation recommendation unit 11 displays on display 32 an operation recommendation image that prompts driver D to operate the driving operation units with a lower operation strength than the previous time.

[0035] 4. Other Embodiments As shown in Figure 5, the operation recommendation images may alternately display an upper body target operation recommendation image 210 that encourages the driver D to operate the steering wheel 33 (corresponding to the upper body driving operation unit in this disclosure) operated by a part of the upper body of the driver D (here, the hands), and a lower body target operation recommendation image 211 that encourages the driver D to operate a pedal (accelerator pedal 34 or brake pedal 35, corresponding to the lower body driving operation unit in this disclosure) operated by a part of the lower body of the driver D (here, the soles of the feet).

[0036] 5 shows the display timing of the operation recommendation images along the time axis t, and the operation recommendation unit 11 displays an upper body target operation recommendation image 210 on the display 32 at t1 and t3, which encourages the driver to operate the steering wheel 33, and displays a lower body target operation recommendation image 211 on the display 32 at t2 and t4, which encourages the driver to operate the pedals. In this way, by alternately displaying the upper body target operation recommendation image 210 and the lower body target operation recommendation image 211 on the display 32, the driver D can be made to perform upper body and lower body exercises in a balanced manner. The upper body target operation recommendation image corresponds to the upper body target operation recommendation information of the present disclosure, and the lower body target operation recommendation information corresponds to the lower body target operation recommendation information of the present disclosure.

[0037] In the above embodiment, a vehicle 100 is used as an example of a moving body of the present disclosure, but the moving body of the present disclosure can be switched between a manual driving mode and an automatic driving mode, and the present invention can also be applied to other types of moving bodies (aircraft, ships, etc.) that are equipped with a driving operation unit.

[0038] In the above embodiment, the operation recommendation unit 11 displays the operation recommendation image on the display 32, but the operation recommendation image may be displayed on the display unit of the communication terminal 50 by communicating with the communication terminal 50 via the communication unit 2. In this case, the communication terminal 50 corresponds to the information output device of the present disclosure.

[0039] In the above embodiment, the operation recommendation unit 11 displayed an operation recommendation image on the display 32 as the operation recommendation information of the present disclosure. However, the operation recommendation information of the present disclosure may also be configured to output an operation recommendation voice from the speaker 31, which voice prompts the driver to operate the driving operation unit. Alternatively, the operation recommendation unit 11 may display an operation recommendation image on the display 32 and output the operation recommendation voice from the speaker 31. Furthermore, the operation recommendation voice may be output from the speaker of the communication terminal 50 by communicating with the communication unit 2. In this case, the communication terminal 50 corresponds to the information output device of the present disclosure.

[0040] In the above embodiment, an example has been shown in which the mobility support device 1 is mounted on the vehicle 100, but the mobility support device of the present disclosure may also be configured as an app (application program) on the communication terminal 50. In this case, the communication terminal 50 recognizes whether the vehicle 100 is traveling in manual driving mode or autonomous driving mode through communication with the ECU 3, and also recognizes the operation status of the driving operation unit. The communication terminal 50 then displays an operation recommendation image on the display unit of the communication terminal 50 or the display 32 of the vehicle 100, and outputs an operation recommendation sound from the speaker of the communication terminal 50 or the speaker 31 of the vehicle 100.

[0041] In the above embodiment, the steering wheel 33, accelerator pedal 34, and brake pedal 35 are shown as driving operation parts, but other driving operation parts such as a control stick or rudder pedals when the moving body is an aircraft may also be used.

[0042] In the above embodiment, the operation status recognition unit 12 recognizes the operation status of the driving operation units based on the detection signals of the steering sensor 33 a, the accelerator pedal sensor 34 a, and the brake pedal sensor 35 a. In another embodiment, the operation status recognition unit 12 may recognize the operation status of the driving operation units by the driver D by extracting an image portion of the driver D from the image captured by the driver monitor camera 30.

[0043] In the above embodiment, the operation status recognition unit 12 is provided to recognize the operation status of the driving operation unit by the driver D, but the operation status recognition unit 12 may be omitted and only the operation recommendation information may be output by the operation recommendation unit 11.

[0044] 2 is a schematic diagram showing the configuration of the mobility support device 1 divided by main processing content to facilitate understanding of the present invention, but the configuration of the mobility support device 1 may be divided in other ways. Furthermore, the processing of each component may be executed by one hardware unit or multiple hardware units. Furthermore, the processing of each component shown in FIG. 4 may be executed by one program or multiple programs.
