Description
Technical Field
The present invention relates to a vehicle seat device capable of adjusting a seat position.
Background
Conventionally, as such a vehicle seat device, for example, a vehicle seat device described in patent document 1 is known. The vehicle seat device includes a plurality of operation knobs (operation portions) disposed on side portions of a seat cushion (seat portion). When the user moves and operates any one of the operation knobs in one direction, the corresponding electric drive source is driven, and the seat position is adjusted.
Patent document 1: japanese patent application laid-open No. 2010-235067
However, since the operation knob may be touched by the body of the user or the like due to an accident, the electric drive source may be driven in response thereto. At this time, the seat position is misadjusted. Accordingly, control is performed to slightly delay the timing of starting the output of the drive signal to the electric drive source with respect to the timing of switching the switch signal output by the switch corresponding thereto from the off state to the on state in response to the movement operation of the operation knob. That is, after a predetermined switching operation determination time elapses after the operation switch is switched from the off state to the on state, the output of the drive signal to the electric drive source is started.
However, since the operation knob disposed on the side of the seat cushion is exposed on the door side of the vehicle, for example, in a situation where the body of the user is touched when getting on or off the vehicle, the electric drive source may still be driven, and there is room for improvement in this point.
Disclosure of Invention
The invention aims to provide a seat device for a vehicle, which can restrain the position of the seat from being adjusted by mistake.
The vehicle seat device for solving the above problems is provided with: an operation knob disposed on a side portion of a door side of a seat cushion serving as a seat portion of a seat; a switch which is interlocked with the movement operation of the operation knob and outputs a switching signal for logic switching; an electric drive source mechanically cooperating with the seat and capable of adjusting a seat position of the seat; a drive control unit that outputs a drive signal to the electric drive source for adjusting a seat position of the seat by performing a switching operation for a certain time period from a logical switching of the switching signal in conjunction with a movement operation of the operation knob; and a detection unit that detects a switch between a closed state and an open state of the door or a switch between a hold state and a release state of the door by the door lock, wherein the drive control unit includes an adjustment unit that detects a switch from the door closed state to the open state or a switch from the self-hold state to the release state until a determination sensitivity adjustment time elapses, during which the adjustment unit adjusts the switching operation determination time so that it is difficult to start output of the drive signal.
According to this configuration, the switching from the door self-closing state to the open state or the switching from the self-holding state to the release state is detected, and the drive control unit adjusts the switching operation determination time by the adjustment unit so that the output of the drive signal is difficult to start until the determination sensitivity adjustment time has elapsed. Therefore, for example, even if the user touches the operation knob when getting on/off the vehicle, the user can suppress the possibility of driving the electric drive source. This can suppress erroneous adjustment of the seat position when the user gets on or off the vehicle.
In the vehicle seat device, it is preferable that the operation knob includes a downward movement component during the movement operation.
According to this configuration, the operation knob includes a downward movement component in the movement operation, and when the operation knob is pushed downward, the switching signal is highly likely to be logically switched. On the other hand, when the user gets on or off the vehicle, the user touches the operation knob, and the operation knob is highly likely to be pressed downward. In this way, the erroneous adjustment of the seat position can be appropriately suppressed for the operation knob including the downward movement component in the movement operation, which is likely to be erroneously pressed when the vehicle gets on or off.
Preferably, the vehicle seat device includes an operation switch that outputs an operation signal indicating an intention to easily start output of the drive signal, and the drive control unit includes an adjustment suspension unit that suspends adjustment of the switch operation determination time by the adjustment unit after output of the operation signal.
According to this configuration, for example, when the user opens the door in a closed state and sweeps the door, if the operation switch is operated to output the operation signal, the adjustment of the switching operation determination time by the adjustment section is stopped by the adjustment stopping section. Therefore, the user can adjust the seat position more smoothly by the moving operation of the operation knob.
[ Effect of the invention ]
The invention has the effect of inhibiting the error adjustment of the seat position.

Detailed Description
An embodiment of the vehicle seat device will be described below.
As shown in fig. 1, a pair of lower rails 1 that are juxtaposed in the width direction of the seat and extend in the front-rear direction are fixed to the floor of the vehicle, and an upper rail 2 is attached to each of the two lower rails 1 so as to be movable in the front-rear direction.
Brackets 3 made of plate material are erected on the upper rails 2. Further, the seats 6 forming the seating portions of the passengers are supported by the respective brackets 3 via front links 4 and rear links 5 disposed at the front and rear portions. The seat 6 includes a seat cushion 7 forming a seat portion, a seat back 8 rotatably supported by a rear end portion of the seat cushion 7, and a headrest 9 supported by an upper end portion of the seat back 8.
The front-rear position of the seat 6 can be adjusted by relatively moving the lower rail 1 and the upper rail 2 on both sides, and the up-down position of the seat 6 can be adjusted by raising and lowering the front link 4 and the rear link 5 on both sides. In addition, the inclination angle of the front portion of the seat 6 with respect to the rear portion of the seat cushion 7 can be adjusted, and the inclination angle of the seatback 8 with respect to the seat cushion 7 can be adjusted. The up-down position of the headrest 9 can be adjusted by lifting and lowering the headrest 9 relative to the seatback 8. Thus, for example, the seated person of the seat 6 can adjust the position of the line of sight with respect to his/her physique.
A first operation knob 41 and a second operation knob 42 as operation knobs are mounted on one side of the seat cushion 7, that is, on a side of a door side, not shown, of the right side for getting on and off the seat 6 toward the front of the seat 6. As shown in fig. 2, the first operation knob 41 extends in the front-rear direction, and has an outer shape that mimics a side view of the seat cushion 7. The second operation knob 42 extends in the up-down direction and has an outer shape that mimics a side view of the seatback 8.
Here, the movement operation of the first operation knob 41 in the forward direction Df1 and the rearward direction Dr1 is an operation of moving the seat 6 in the forward direction and the rearward direction, respectively. The movement operation of the rear end of the first operation knob 41 to the upper direction Du1 and the lower direction Dd1 is an operation of moving the seat 6 to the upper direction and the lower direction, respectively. The movement operation of the front end of the first operation knob 41 to the upper direction Du2 and the lower direction Dd2 is an operation of increasing and decreasing the inclination angle of the front portion with respect to the rear portion of the seat cushion 7, respectively. The tilting operation of the second operation knob 42 to the front Df2 and the rear Dr2 is an operation of tilting the seatback 8 forward and backward, respectively. The movement operation of the second operation knob 42 to the upper direction Du3 and the lower direction Dd3 is an operation of moving the headrest 9 to the upper direction and the lower direction with respect to the seatback 8, respectively.
Next, an electrical structure of the present embodiment will be described.
As shown in fig. 3, the seat 6 is provided with a seat ECU10 as a drive control unit, which is composed mainly of a microcomputer, for example, a slide switch 11, a lifter switch 12, a tilt switch 13, a recliner switch 14, and a headrest switch 15, which are electrically connected to the seat ECU 10. The seat 6 is provided with a slide drive motor 21, a lift drive motor 22, a tilt drive motor 23, a reclining drive motor 24, and a headrest drive motor 25, which are electrically connected to the seat ECU 10.
The slide switch 11 is a three-position switch, and the movable blade cooperates with the first operation knob 41. When the first operation knob 41 is moved to either one of the front Df1 and the rear Dr1, the slide switch 11 is interlocked with this movement, and a switching signal corresponding to the movement operation direction is outputted from the off-to-on switching logic. The slide drive motor 21 is drivingly connected to a slide mechanism 31 for adjusting the front-rear position of the seat 6, which is composed of two lower rails 1, two upper rails 2, and the like. When the slide drive motor 21 is driven, the seat 6 moves forward or backward in accordance with the rotation direction. When the drive of the slide drive motor 21 is stopped, the seat 6 is held at the front-rear position. If the logic of the switch signal of the slide switch 11 is switched, the seat ECU10 drives and controls the slide drive motor 21 so as to move the seat 6 in the front-rear direction against the moving operation direction of the first operation knob 41 corresponding to the switch signal.
The elevation switch 12 is a three-position switch, and the movable blade cooperates with the first operation knob 41. When the rear end of the first operation knob 41 is moved upward Du1, the up-down switch 12 is interlocked with this, and a switching signal corresponding to the moving operation direction is outputted from the off-to-on switching logic. Similarly, when the rear end of the first operation knob 41 is moved to the downward direction Dd1, the up-down switch 12 moves in conjunction with this, and the switch signal Sw1 corresponding to the moving direction is outputted from the off-to-on switching logic. The lift drive motor 22 as an electric drive source is drivingly connected to a lift mechanism 32 that adjusts the vertical position of the seat 6, which is composed of two front links 4, two rear links 5, and the like. When the lift drive motor 22 is driven, the seat 6 is lifted or lowered in accordance with the rotation direction thereof. When the drive of the lift drive motor 22 is stopped, the seat 6 is held at the up-down position. If the logic of the switching signal of the up-down switch 12 is switched, the seat ECU10 drives and controls the up-down drive motor 22 so as to move the seat 6 in the up-down direction against the moving operation direction of the rear end of the first operation knob 41 corresponding to the switching signal. For example, if the logic of the switch signal Sw1 of the up-down switch 12 is switched, the seat ECU10 drives and controls the up-down drive motor 22 so as to move the seat 6 downward against the lower Dd1, which is the moving operation direction of the rear end of the first operation knob 41.
The tilt switch 13 is a three-position switch, and the movable blade cooperates with the first operation knob 41. When the tip of the first operation knob 41 is moved upward Du2, the tilt switch 13 is interlocked with this movement, and a switching signal corresponding to the movement operation direction is outputted from the off-to-on switching logic. Similarly, when the tip of the first operation knob 41 is moved to the downward direction Dd2, the tilt switch 13 switches the logic from off to on and outputs a switch signal Sw2 corresponding to the movement direction in conjunction with the movement. The tilting drive motor 23 as an electric drive source is drivingly connected to a tilting mechanism 33 that adjusts the vertical position of the front portion with respect to the rear portion of the seat cushion 7. When the reclining drive motor 23 is driven, the front portion of the seat cushion 7 is raised or lowered relative to the rear portion in accordance with the rotation direction thereof. When the drive of the tilting drive motor 23 is stopped, the front portion of the seat cushion 7 is held at the up-down position. When the logic of the switch signal of the tilt switch 13 is switched, the seat ECU10 drives and controls the tilt drive motor 23 so as to move the front portion of the seat cushion 7 in the up-down direction in accordance with the direction of the movement operation of the front end of the first operation knob 41 corresponding to the switch signal. For example, when the logic of the switch signal Sw2 of the tilt switch 13 is switched, the seat ECU10 drives and controls the lift drive motor 22 so as to move the front portion of the seat cushion 7 downward in accordance with the lower Dd2, which is the direction of the movement operation of the front end of the first operation knob 41.
The recliner switch 14 is a three-position switch with a movable slide cooperating with the second operating knob 42. When the second operation knob 42 is tilted forward Df2, the recliner switch 14 is interlocked with this operation, and a switching signal corresponding to the moving operation direction is outputted from the off-to-on switching logic. Similarly, when the second operation knob 42 is tilted rearward Dr2, the recliner switch 14 switches the logic from off to on in response to the switch signal Sw4 corresponding to the moving operation direction, and outputs the switch signal. As can be seen from fig. 2, the movement operation of the second operation knob 42 at this time includes a downward movement component. The reclining drive motor 24 as an electric drive source is drivingly connected to a reclining mechanism 34 that adjusts the inclination angle of the seat back 8 with respect to the seat cushion 7. If the reclining drive motor 24 is driven, the seat back 8 is tilted forward or backward corresponding to the rotational direction thereof. When the drive of the reclining drive motor 24 is stopped, the reclining angle of the seat back 8 is maintained. If the logic of the switch signal of the recliner switch 14 is switched, the seat ECU10 drives and controls the recliner drive motor 24 so as to tilt the seat back 8 forward or backward against the moving operation direction of the second operation knob 42 corresponding to the switch signal. For example, if the logic of the switching signal Sw4 of the recliner switch 14 is switched, the seat ECU10 drives and controls the recliner drive motor 24 in order to recline the seat back 8 against the rear Dr2, which is the moving operation direction of the second operation knob 42.
The headrest switch 15 is a three-position switch, and the movable blade cooperates with the second operation knob 42. When the second operation knob 42 is moved upward Du3, the headrest switch 15 is interlocked with this movement, and a switching signal corresponding to the movement operation direction is outputted from the off-to-on switching logic. Similarly, when the second operation knob 42 is moved to the downward direction Dd3, the headrest switch 15 switches the switch signal Sw3 corresponding to the movement operation direction from off to on and outputs the switch signal Sw from off to on. The headrest driving motor 25 as an electric driving source is drivingly connected to a headrest elevating mechanism 35 for adjusting the up-down position of the headrest 9. When the headrest driving motor 25 is driven, the headrest 9 is raised or lowered in accordance with the rotation direction thereof. When the driving of the headrest driving motor 25 is stopped, the headrest 9 is held at the up-down position at that time. If the logic of the switch signal of the headrest switch 15 is switched, the seat ECU10 drives and controls the headrest driving motor 25 so as to move the headrest 9 in the up-down direction against the moving operation direction of the second operation knob 42 corresponding to the switch signal. For example, if the logic of the switch signal Sw3 of the headrest switch 15 is switched, the seat ECU10 drives and controls the headrest drive motor 25 so as to move the headrest 9 downward against the lower Dd3, which is the moving operation direction of the second operation knob 42.
The seat ECU10 is electrically connected to a gate switch 16 as a detection unit, and the gate switch 16 detects switching between a closed state and an open state of the door. The gate switch 16 outputs a gate control signal Sc for switching the logic from off to on when the gate is switched from the closed state to the open state.
The seat ECU10 is electrically connected to a lock switch 17 as a detection unit, and the lock switch 17 detects switching between a door holding state and a door releasing state of a door lock, not shown. For example, the lock switch 17 outputs a lock signal Sl for switching the logic from off to on when the gate is switched from the hold state to the release state.
Next, a general relationship between the switching signals from any one of the switches 11 to 15 input to the seat ECU10 and the driving signals output from the seat ECU10 for driving and controlling the driving motors 21 to 25 corresponding thereto will be described.
As shown in fig. 4 (a) and (b), when the switching signal from any one of the switches 11 to 15 is switched from off to on at time t1, the seat ECU10 starts outputting the driving signal so that the corresponding driving motor 21 to 25 rotates in the rotation direction at time t2 after the switching operation determination time Td is delayed from time t1. Thereby, the adjustment of the corresponding seat position is started. That is, after the switch operation determination time Td is delayed from the start of the movement operation of the first or second operation knob 41, 42, the adjustment of the seat position is started. This is because, even if the user touches the first or second operation knob 41, 42 by accident, the driving motors 21 to 25 are not immediately driven in response thereto.
The seat ECU10 normally sets the switching operation determination time Td as a prescribed first switching operation determination time Td1. The first switch operation determination time Td1 is set to a minute time to such an extent that no uncomfortable feeling is felt for a response delay from when the user operates the first or second operation knob 41, 42 until the driving of the drive motors 21 to 25 is started.
Next, a relationship between the gate signal Sc from the gate switch 16 input to the seat ECU10 and the switch operation determination time Td will be described. This relationship is limited to the case where the switch signals Sw1 to Sw4 are switched from off to on in response to the operation of the first or second operation knobs 41 and 42.
As shown in fig. 5 (a) and (b), when the gate signal Sc is switched from off to on at time t0, the seat ECU10 switches the switching operation determination time Td from the normal first switching operation determination time Td1 to a predetermined second switching operation determination time Td2 longer than the normal first switching operation determination time Td1. Then, when the predetermined determination sensitivity adjustment time T1 elapses from the time T0, the seat ECU10 switches the switching operation determination time Td from the second switching operation determination time Td2 to the normal first switching operation determination time Td1. That is, the switching from the door self-closing state to the open state is detected until the determination sensitivity adjustment time T1 elapses, during which the seat ECU10 as the adjustment unit 10a adjusts the switching operation determination time Td so that it is difficult to start the output of the drive signal. The determination sensitivity adjustment time T1 is set to be a time required for a user to open the door in the closed state until the entrance/exit is completed, for example, 5 to 10 seconds.
In addition, in the seat ECU10, even if the gate signal Sc is switched from on to off before the determination sensitivity adjustment time T1 elapses, the seat ECU10 as the adjustment suspension portion 10b switches the switch operation determination time Td from the second switch operation determination time Td2 to the normal first switch operation determination time Td1. This is because if the switch from the open state to the closed state of the door is detected, there is a high possibility that the user gets on and off the vehicle.
As described above, the adjustment of the switching operation determination time Td in the determination sensitivity adjustment time T1 is limited to the case where the switching signals Sw1 to Sw4 are switched from off to on. That is, as shown in fig. 7, the first or second operation knob 41, 42 is defined to include a downward movement component in the movement operation. Specifically, the logic of the changeover switch signal Sw1 corresponds to a movement operation of the rear end of the first operation knob 41 downward Dd 1. The logic of the change-over switch signal Sw2 corresponds to a movement operation of the tip of the first operation knob 41 downward Dd 2. The logic of the change-over switch signal Sw3 corresponds to the movement operation of the second operation knob 42 in the downward direction Dd 3. The logic of the change-over switch signal Sw4 corresponds to the tilting operation of the second operation knob 42 to the rear Dr 2. The seat ECU10 adjusts the switching operation determination time Td only when the downward movement component is included in the movement operation of the first or second operation knob 41, 42, and otherwise does not adjust the switching operation determination time Td.
Next, an adjustment manner in which the switch operation determination time Td is adjusted by the seat ECU10 will be collectively described according to a flowchart. Further, at the start of the process, the switching operation determination time Td is set to the first switching operation determination time Td1.
As shown in fig. 6, when the process moves to this routine, in step S101, the seat ECU10 determines whether or not a switch from the door self-closing state to the open state is detected. Then, the seat ECU10 waits until the switch from the door closed state to the open state is detected, and in step S102, switches the switch operation determination time Td to the second switch operation determination time Td2.
Then, in step S103, the seat ECU10 determines whether or not the switching from the door self-closing state to the open state is detected, and the determination sensitivity adjustment time T1 elapses. If it is determined that the determination sensitivity adjustment time T1 has not elapsed since the switch from the door self-closing state to the open state was detected, the seat ECU10 determines in step S104 whether or not the switch from the door open state to the closed state was detected.
If it is determined that the switch from the open state to the closed state of the door is not detected, the seat ECU10 returns to step S103, and the same process is repeated. On the other hand, if it is determined in step S103 that the switching from the door self-closing state to the open state is detected that the determination sensitivity adjustment time T1 has elapsed, the seat ECU10 switches the switch operation determination time Td to the first switch operation determination time Td1 in step S105, and ends the process. Similarly, if it is determined in step S104 that the switch from the door open state to the door closed state is detected, the seat ECU10 switches the switch operation determination time Td to the first switch operation determination time Td1 in step S105, and ends the process.
The operation and effects of the present embodiment will be described.
(1) In the present embodiment, the switching from the door self-closing state to the open state is detected until the determination sensitivity adjustment time T1 elapses, and during this time, the seat ECU10 adjusts the switching operation determination time Td by the adjustment unit 10a so that it is difficult to start the output of the drive signal. Therefore, for example, when the user gets on or off the vehicle, even if the user touches the first or second operation knob 41 or 42, the possibility of driving the drive motors 22 to 25 can be suppressed. This can suppress erroneous adjustment of the seat position when the user gets on or off the vehicle.
(2) In the present embodiment, the first or second operation knobs 41 and 42 include downward movement components in the movement operation, so that the logic of the switch signals Sw1 to Sw4 is likely to be switched when the first or second operation knobs are pressed downward. On the other hand, when the user gets on or off the vehicle, the user may touch the first or second operation knob 41 or 42 and press the operation knob 41 or 42 downward. As described above, the erroneous adjustment of the seat position can be appropriately suppressed for the operation knobs 41 and 42 including the downward movement component in the movement operation, which is likely to be erroneously pressed when the vehicle gets on or off.
(3) In the present embodiment, even if the switch from the door self-closing state to the open state is detected, the elapse of the determination sensitivity adjustment time T1 is not waited, and if the switch from the door open state to the closed state is detected, the adjustment of the switching operation determination time Td by the adjustment section 10a is suspended by the adjustment suspension section 10b. Thereby, the switching operation determination time Td is adjusted in such a manner that the output of the driving signal is easily started. Therefore, in a case where it can be determined that the user has completed getting on/off the vehicle, the user can more smoothly adjust the seat position by the movement operation of the first or second operation knob 41, 42.
(4) In the present embodiment, the switch operation determination time Td is set to a minute time, so that it is possible to eliminate a situation in which the responsiveness of adjusting the seat position is impaired by the movement operation of the first or second operation knobs 41, 42.
The present embodiment can be modified as follows. The present embodiment and the following modification examples can be combined and implemented within a range that is not technically contradictory.
As shown in fig. 8, when the degree of opening of the door by the entrance/exit, that is, the door opening can be detected by an appropriate sensor, the adjustment unit 10a may lengthen the switching operation determination time Td as the door opening decreases. This is because, for example, when the door opening degree is reduced due to a narrow gap between the vehicle and the adjacent vehicle, the frequency of the user's legs or the like touching the first or second operation knobs 41, 42 increases when the user gets on or off the vehicle. At this time, the adjustment unit 10a can appropriately adjust the switching operation determination time Td against a decrease in the door opening degree, which increases the frequency with which the body of the user gets on or off the vehicle.
In addition, the switching operation determination time Td may also be prolonged in proportion to the decrease in the door opening degree. Alternatively, the switching operation determination time Td may be extended stepwise as the door opening degree decreases.
As shown in fig. 3, an operation switch 46 that outputs an operation signal Sh indicating an intention to easily start output of a drive signal may be provided at an appropriate position of the vehicle, for example, at the seat 6, the instrument panel, or the like. The seat ECU10 as the adjustment suspension unit 10b may suspend the adjustment of the switching operation determination time Td by the adjustment unit 10a after the output of the operation signal Sh. That is, the switching operation determination time Td may be maintained at the first switching operation determination time Td1 regardless of the opening/closing state of the door.
At this time, for example, when the user opens the door in the closed state and sweeps the door, if the operation switch 46 is operated to output the operation signal Sh, the adjustment of the switch operation determination time Td by the adjustment stopping portion 10a is stopped by the adjustment stopping portion 10b. That is, even if the user does not wait until the determination sensitivity adjustment time T1 elapses from opening the door in the closed state, the switch operation determination time Td can be immediately switched to the first switch operation determination time Td1 by operating the operation switch 46. Therefore, the user can more smoothly adjust the seat position by the moving operation of the first or second operation knob 41, 42.
Further, the seat ECU10 may set the switching operation determination time Td to "0" after the output of the operation signal Sh.
In the above embodiment, even if the switch from on to off is detected after the switch from off to on of the gate signal Sc is detected, the switching operation determination time Td may be continuously adjusted so that the output of the drive signal is difficult to start until the determination sensitivity adjustment time T1 elapses. That is, the adjustment stopping portion 10b may be omitted.
In the above embodiment, the determination of the lapse of the sensitivity adjustment time T1 may be started from the start of the switching of the gate signal Sc from off to on. In contrast, the determination of the lapse of the sensitivity adjustment time T1 may be started from the start of the switching of the lock signal Sl from off to on. That is, the switching from the self-holding state to the release state of the door lock to the door may be detected until the determination sensitivity adjustment time T1 elapses, and during this time, the adjustment unit 10a may adjust the switching operation determination time Td so that the output of the drive signal is difficult to start.
In the above embodiment, even if the determination sensitivity adjustment time T1 does not elapse, if the switching of the gate signal Sc from on to off is detected, the adjustment of the switch operation determination time Td is stopped. In contrast, the adjustment of the switching operation determination time Td may be stopped when the switch from on to off of the lock signal Sl is detected. That is, the adjustment suspension unit 10b may suspend the adjustment of the switching operation determination time Td when the door lock is detected to switch from the released state to the held state. In this case, the user can more smoothly adjust the seat position by the movement operation of the first or second operation knob 41, 42 even in the case where the user can be judged to have finished getting on or off the vehicle.
In the above embodiment, the switching from the door self-closing state to the open state or the switching from the door lock self-holding state to the release state may be detected, and the adjustment unit 10a may adjust the switching operation determination time Td so that it is difficult to start the output of the drive signal, based on at least one of the vehicle power supply state, the result of recognition of the captured image by the camera, and the result of detection by the seating sensor, until the determination sensitivity adjustment time T1 elapses. At this time, the adjustment unit 10a can more accurately grasp the getting on/off of the user by referring to at least one of the vehicle power supply state such as the voltage, the recognition result of the captured image by the camera, and the detection result of the seating sensor at the time of adjustment of the switching operation determination time Td.
In the above embodiment, the adjustment direction (see fig. 7) of the seat position related to the adjustment of the switch operation determination time Td may be arbitrarily changed. For example, the adjustment unit 10a may adjust the switch operation determination time Td so that it is difficult to start the output of the drive signal for the movement operation of the first operation knob 41 for moving the seat 6 forward and backward to the front Df1 and the rear Dr1, respectively. Alternatively, instead of or in addition to the movement operation of the rear end of the first operation knob 41 that moves the seat 6 downward to the downward direction Dd1, the adjustment unit 10a may adjust the switch operation determination time Td so that it is difficult to start the output of the drive signal.
That is, the type and adjustment direction of the seat position in which the adjustment of the switching operation determination time Td for which the output of the drive signal is difficult to start may be arbitrarily changed depending on the arrangement of the operation knob, the switching structure, the height of the seat 6, and other vehicle components.
Technical ideas that can be grasped according to the above embodiments and modified examples are described.
(i) a vehicle seat device, wherein, in the vehicle seat device,
the drive control unit includes an adjustment suspension unit that suspends adjustment of the switching operation determination time by the adjustment unit when the switching of the door from the open state to the closed state or the switching of the door from the released state to the held state is detected before the determination sensitivity adjustment time elapses.
According to this configuration, even if the switching from the door self-closing state to the open state or the switching from the self-holding state to the release state is detected, the adjustment of the switching operation determination time by the adjustment suspending unit is suspended by the adjustment suspending unit if the switching from the door self-closing state to the closed state or the switching from the release state to the hold state is detected without waiting until the determination sensitivity adjustment time elapses. Therefore, in a situation where it can be determined that the user has completed getting on/off the vehicle, the user can more smoothly adjust the seat position by the movement operation of the operation knob.
(ii) a vehicle seat device, wherein, in the vehicle seat device,
the switching from the door self-closing state to the open state or from the self-holding state to the release state is detected, and the adjustment unit adjusts the switching operation determination time so that the output of the drive signal is difficult to start, based on at least one of a vehicle power supply state, a result of recognition of a captured image by the camera, and a result of detection by the seating sensor, until the determination sensitivity adjustment time elapses.
According to this configuration, the adjustment unit can more accurately grasp the user's getting on/off by referring to at least one of the vehicle power supply state, the result of recognition of the captured image by the camera, and the result of detection by the seating sensor, when the switch operation determination time is adjusted.
(iii) a vehicle seat device, wherein, in the vehicle seat device,
the adjustment unit adjusts the switching operation determination time so that it becomes more difficult to start the output of the drive signal as the door opening degree of the door decreases.
According to this configuration, the adjustment unit can appropriately adjust the switch operation determination time in comparison with a decrease in the door opening degree, which increases the frequency with which the user touches the body or the like, when the user gets on or off the vehicle.
