[0003] [Patent Document 1] JP 2018-149866 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, with the technology of Patent Document 1, if a part of the seat (e.g., a footrest) is provided near a surrounding component (e.g., a drive device, a floor surface, etc.), there is a risk that a part of the seat will interfere with the surrounding component when the seat position is rotated. [Means for solving the problem]

[0005] In order to solve the above-mentioned problems, a vehicle control device in one embodiment is a vehicle control device that has the function of tilting the entire seat based on the driving condition of the vehicle, wherein the seat has a rotating member that can rotate in the fore-and-aft direction of the vehicle, and when tilting the entire seat, the control device rotates the rotating member according to the overall inclination state of the seat. Effect of the Invention

[0006] According to the vehicle control device of one embodiment, it is possible to prevent a part of the seat from interfering with surrounding members when the entire seat is tilted. [Brief description of the drawings]

[0007] [Figure 1] FIG. 1 is a diagram showing a configuration of an active sheet according to an embodiment; [Diagram 2] FIG. 1 is a diagram showing an example (first example) of control of a seat state by a control device according to an embodiment; [Diagram 3] FIG. 2 is a diagram showing an example (second example) of control of the state of a seat by a control device according to an embodiment; DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0009] (Active Sheet 10 Configuration) Fig. 1 is a diagram showing the configuration of an active seat 10 according to an embodiment. The active seat 10 shown in Fig. 1 is installed inside a vehicle. As shown in Fig. 1, the active seat 10 includes a seat 20, a drive device 30, and a control device 40.

[0010] The seat 20 has a back surface 21, a seat surface 22, and a footrest 23. The seat surface 22 is a portion on which a vehicle occupant sits. The back surface 21 is provided so as to extend upward from the rear end of the seat surface 22. The back surface 21 is provided at the rear end of the seat surface 22 so as to be rotatable in the front-rear direction of the vehicle.

[0011] The footrest 23 is an example of a "rotating member." The footrest 23 is provided to extend downward from the front end of the seat surface 22. The footrest 23 is provided at the front end of the seat surface 22 so as to be rotatable in the front-to-rear direction of the vehicle. In FIG. 1, the footrest 23 is in a stored state close to vertical, but can be rotated forward to a use state close to horizontal. The footrest 23 is configured to be extendable and retractable in the front-to-rear direction.

[0012] The driving device 30 can change the state of the seat 20 by driving the seat 20. For example, the driving device 30 can change the overall inclination of the seat 20 by driving the seat surface 22 of the seat 20. Also, for example, the driving device 30 can rotate the footrest 23 between the stored state and the used state by driving the footrest 23 of the seat 20. Also, for example, the driving device 30 can extend and retract the footrest 23 in the front-rear direction by driving the footrest 23 of the seat 20.

[0013] The control device 40 controls the state of the active seat 10 by controlling the drive device 30. For example, the control device 40 can tilt the entire seat 20 in the front-rear or left-right direction based on the vehicle's running state (e.g., deceleration, right-left turns, road vibration, etc.) by controlling the drive device 30, thereby reducing the acceleration of the occupant. Also, for example, when tilting the entire seat 20 forward, the control device 40 can rotate the footrest 23 by controlling the drive device 30 according to the overall tilt state of the seat 20. Also, for example, when tilting the entire seat 20 forward, the control device 40 can retract the footrest 23 by controlling the drive device 30 according to the overall tilt state of the seat 20.

[0014] The control device 40 is configured to include a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc. Each function of the control device 40 described above is realized, for example, by the CPU executing a program stored in the ROM in the control device 40.

[0015] (First Example of Control of the State of the Seat 20 by the Control Device 40) FIG. 2 is a diagram showing an example (first example) of control of the state of the seat 20 by the control device 40 according to one embodiment.

[0016] As shown in FIG. 2, the control device 40 controls the drive device 30 based on the running state of the vehicle, thereby tilting the entire seat 20 downward and forward, thereby reducing the acceleration applied to the occupant.

[0017] Here, as indicated by the dotted line in FIG. 2, if the footrest 23 is left in the stored state, the footrest 23 will interfere with the drive device 30 located behind it.

[0018] Therefore, in the example shown in FIG. 2, the control device 40 according to one embodiment can prevent the footrest 23 from interfering with the drive device 30 by rotating the footrest 23 forward.

[0019] At this time, the control device 40 according to one embodiment can control the rotation amount of the footrest 23 in a stepwise manner according to the overall tilt amount of the seat 20. That is, the control device 40 according to one embodiment can increase the rotation amount of the footrest 23 as the overall tilt amount of the seat 20 increases.

[0020] The appropriate rotation amount of the footrest 23 according to the overall tilt amount of the seat 20 is stored in advance in a memory provided in the control device 40.

[0021] (Second Example of Control of State of Seat 20 by Control Device 40) FIG. 3 is a diagram showing an example (second example) of control of the state of the seat 20 by the control device 40 according to an embodiment.

[0022] As shown in FIG. 3, the control device 40 controls the drive device 30 based on the running state of the vehicle, thereby tilting the entire seat 20 downward and forward, thereby reducing the acceleration applied to the occupant.

[0023] Here, as indicated by the dotted line in FIG. 3, if the footrest 23 is left in the stored state, the footrest 23 will interfere with the floor surface A below it, or with the drive unit 30 behind it.

[0024] Therefore, in the example shown in FIG. 3, the control device 40 according to one embodiment can prevent the footrest 23 from interfering with the floor surface A and the drive device 30 by contracting the footrest 23 upward.

[0025] At this time, the control device 40 according to one embodiment can control the amount of contraction of the footrest 23 in stages according to the overall amount of inclination of the seat 20. That is, the control device 40 according to one embodiment can increase the amount of contraction of the footrest 23 as the overall amount of inclination of the seat 20 increases.

[0026] The appropriate amount of reduction of the footrest 23 according to the overall amount of inclination of the seat 20 is stored in advance in a memory provided in the control device 40.

[0027] Although the preferred embodiments of the present invention have been described in detail above, the present invention is not limited to these embodiments, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims.

[0028] For example, the control device 40 may avoid interference of the footrest 23 with the floor surface A and the drive device 30 by simultaneously rotating the footrest 23 as shown in FIG. 2 and contracting the footrest 23 as shown in FIG.

[0029] Furthermore, for example, if there is a risk of interference with other parts of the seat 20 (e.g., side covers, rear cover, etc.) when the entire seat 20 is tilted, the other parts may also be configured to be operable to avoid interference. In this case, the control device 40 may operate the other parts when the entire seat 20 is tilted to avoid interference with the other parts. [Explanation of symbols]
