Problems solved by technology

[0004] However, in the walking assistance vehicle described in Japanese Patent Application Laid-Open No. 2016-63980, the distance from the base to the user is detected, but the position of the user's feet is not detected, and the walking state cannot be estimated or improved.
Therefore, although the user walks comfortably with the walking assist vehicle, there is a problem that the walking ability gradually decreases because there is no function of improving the walking ability by using the walking assist vehicle for training in walking.

no. 1 approach

[0249] (A) For example, the control device 40 may also pre-store in the storage device 44 the "target teaching travel distance" ( For example, 50m ~ 300m). In addition, when the control device 40 travels in any one of the "walking mode 1", "walking mode 2", and "walking mode 3", based on the detection signals from the respective traveling speed detection devices 64LE, 64RE, The travel distance L from the start of travel is detected.

[0250] Furthermore, the control device 40 may also determine whether the traveling distance L has reached the target teaching traveling distance. Furthermore, when it is determined that the travel distance L has reached the target taught travel distance, the control device 40 may control the travel drive devices 64L, 64R and the walking assistance device 10 to stop. Thus, the user can use the walking assistance device 10 in any of the walking modes of "walking mode 1", "walking mode 2", and "walking mode 3", and can easily determine that the di...

no. 2 approach

[0253] (B) In addition, for example, in the above-mentioned step SB716, the control device 40 starts, via the speaker 66, a periodical sound set to a period equal to the target walking period TS (for example, a rhythmic sound of a metronome with a constant period, a musical instrument In the case of outputting rhythmic sounds, shouts, etc.), the above steps SB210 to SB220 may be performed again to calculate the walking cycle TB.

[0254] Furthermore, the control device 40 may evaluate the user's gait state during the gait training based on the degree of matching of the gait cycle TB with the target gait cycle TS. Furthermore, the control device 40 may display the evaluation result of the user's walking state during the walking training on the operation panel 70 and notify it by sound output via the speaker 66 . Thereby, the user can quickly acquire the evaluation of the walking training, and easily review the contents of the walking training.

[0255] In addition, the control...

no. 3 approach

[0258](C) In addition, for example, the control device 40 may also combine the walking cycle TB (walking state information) calculated in the above-mentioned step SB219 together with the user ID, date and time, traveling speed, acceleration (walking state information), etc. Stored in time series in the walking state storage unit 44A of the storage device 44 (refer to Figure 13 ). In addition, the user ID may be input in advance via the ID input screen provided on the operation panel 70 before the user starts walking training. Here, the storage device 44 functions as an example of a walking state information storage device.

[0259] And, in above-mentioned step SB712, step SB714, step SB715, control device 40 reads out from walking state storage part 44A the newest prescribed number that is stored in correspondence with the user ID of the user, for example, the latest five walking cycles TB. (walking status information). Next, the control device 40 may calculate the average...

Abstract

The invention provides a walking assistance device. The walking assistance device includes: a frame; a plurality of wheels arranged on the frame and including at least one driving wheel; a travel drive device configured to drive the drive wheels; a travel control device configured to control the travel drive device; a walking state acquisition device configured to acquire walking state informationrelated to a walking state of the user for a predetermined amount of time; a target walking state setting device configured to set a target walking state in which the walking state of the user is improved on the basis of the walking state information acquired by the walking state acquisition device; and a teaching control device configured to perform control to teach the target walking state to the user. The travel control device controls the travel drive device on the basis of the target walking state.

Description

technical field [0001] The present disclosure relates to walking assist devices. Background technique [0002] Various technologies related to walking assistance devices for assisting the walking of the elderly and the like have been proposed. For example, in the walking assistance vehicle described in Japanese Patent Application Laid-Open No. 2016-63980, a base supporting the user, a drive unit for moving the base, a distance detection unit for detecting the distance from the base to the user, and a user detection unit are provided. An acting force detection unit that acts on the base body, and a movement control unit that controls the driving unit based on the usage distance or the acting force. The movement control unit performs fall prevention control in which a braking force is applied to the drive unit to decelerate the base when the used distance is greater than a predetermined distance threshold. In addition, the movement control unit is configured to perform retur...
