The present disclosure relates to a seat control device that controls seat operation.

As in Patent Document 1, conventionally, the seat of a vehicle is provided with an armrest as a place where an occupant such as a driver puts his / her arm elbow or hand when sitting. The position of this armrest can be switched between a storage position in which the armrest is stored and an extension position in which the arm or elbow can be placed. Currently, many armrests of this type are manually repositioned.

JP-A-2018-199370

When switching the position of the armrest, the occupant had to manually push out and retract the armrest, so this position adjustment operation sometimes felt troublesome. Further, if the reclining angle of the seat is changed with respect to the set armrest position, the posture of the occupant changes and the armrest position becomes inappropriate. Therefore, there is a problem that it takes time and effort to adjust the position of the armrest again.

An object of the present disclosure is to provide a seat control device that enables simplification of armrest position adjustment.

The seat control device 3 includes an acquisition unit 42 that acquires information related to seat operation such that the posture of an occupant seated on the seat 2 changes. The acquisition unit 42 is provided in the computer 4. The acquisition unit 42 of this example is a detection signal related to the seat operation from a detection unit (first detection unit 17 in this example) that detects the seat operation such that the posture (for example, the line of sight) of the occupant seated on the seat 2 is switched. Acquire S1.

The seat control device 3 includes an adjusting unit 43 that adjusts the state of the armrest 9 according to the mode of seat operation related to the position adjustment of the seat 2. The adjusting unit 43 is provided in the computer 4. The adjusting unit 43 of this example adjusts the state of the armrest 9 based on the detection signal S1 so that the armrest 9 of the seat 2 is in a mode based on the seat operation. The adjusting unit 43 is based on the detection signal S1 of the detection unit (first detection unit 17 in this example) that detects the reclining mode of the seat 2, so that the armrest 9 is in a mode corresponding to the reclining state. The state of the armrest 9 is adjusted via the slide drive device 20 and the arm height drive device 31.

Next, the operation of the seat control device 3 of the present embodiment will be described with reference to FIG.

As shown in FIG. 5, in step 101, the adjusting unit 43 receives the detection signal which is the armrest position data (armrest position data) from the second detection units 25, 28, 36, 39 as the information related to the position of the armrest 9. Acquire S2 to S5. In the case of this example, the armrest position data includes a detection signal S2 acquired from the second detection unit 25 of the right slide armrest 21, a detection signal S3 acquired from the second detection unit 28 of the left slide armrest 22, and a right height armrest. There is a detection signal S4 acquired from the second detection unit 36 of the 32, and a detection signal S5 acquired from the second detection unit 39 of the left height armrest 33. In this way, the adjusting unit 43 acquires the current positions of the slide position and the height position in both the right armrest 9a and the left armrest 9b.

In step 102, the acquisition unit 42 acquires the detection signal S1 which is the reclining position data (reclining position data) from the first detection unit 17 as the information related to the reclining angle of the seat 2.

In step 103, the adjusting unit 43 calculates the target position of the armrest operation based on the acquired reclining position data (detection signal S1). In this way, the target value of the armrest operation according to the reclining angle of the seat 2 is set. The target position is set in each of the slide direction and the height direction of the armrest 9.

In step 104, the adjusting unit 43 calculates the difference K1 between the current position of the armrest 9 and the target position. In this example, the parameters related to the current position of the armrest 9 include four parameters: the slide position of the right armrest 9a, the height position of the right armrest 9a, the slide position of the left armrest 9b, and the height position of the left armrest 9b. Therefore, for each of these parameters, the difference K1 from the target position is obtained.

In step 105, the adjusting unit 43 determines whether or not the difference K1 between the current position of the armrest 9 and the target position is equal to or greater than the threshold value. In the case of this example, since the parameters related to the current position of the armrest 9 include the above-mentioned four parameters, it is determined whether or not the difference K1 is equal to or greater than the threshold value for each of the four parameters. In this determination, if the difference K1 does not exceed the threshold value in any case, the process proceeds to step 110, and if at least one difference K1 exceeds the threshold value, the process proceeds to step 106.

In step 106, the adjusting unit 43 calculates the difference K2 between the positions of the right armrest 9a and the left armrest 9b. In the case of this example, the difference K2 between the positions of the right armrest 9a and the left armrest 9b includes a difference in the sliding direction and a difference in the height direction. Therefore, here, in the right armrest 9a and the left armrest 9b, the difference K2 is obtained in the slide direction and the height direction, respectively. It should be noted that the factors that cause the difference K2 between the right armrest 9a and the left armrest 9b are considered to be the way the load is applied at the time of the previous use, the misalignment at the time of storage, and the secular change.

In step 107, the adjusting unit 43 determines whether or not the difference K2 between the right armrest 9a and the left armrest 9b is equal to or greater than the threshold value. In the case of this example, since the difference K2 has a value in the slide direction and a value in the height direction, it is determined whether or not the difference K2 is equal to or greater than the threshold value for each of them. In this determination, if at least one of the differences K2 is equal to or greater than the threshold value, the process proceeds to step 108, and if neither difference K2 is equal to or greater than the threshold value, the process proceeds to step 109.

When the difference K2 between the right armrest 9a and the left armrest 9b is equal to or greater than the threshold value, the adjusting unit 43 operates the right armrest 9a and the left armrest 9b with speed control in step 108. That is, when the right armrest 9a and the left armrest 9b are operated, the driving speeds of the operations are made different so that the right armrest 9a and the left armrest 9b reach the target positions at the same time. Specifically, of the right armrest 9a and the left armrest 9b, the one closer to the target position is operated at a lower speed than usual, and the one far from the target position is operated at a normal speed to have a speed difference in operation. Let me. Further, in the case of this example, since the right armrest 9a and the left armrest 9b can be moved in both the sliding direction and the height direction, the positions are adjusted in each direction.

On the other hand, if the difference K2 between the right armrest 9a and the left armrest 9b does not exceed the threshold value, the adjusting unit 43 operates the right armrest 9a and the left armrest 9b in step 109 without speed control. In the case of this example, the right armrest 9a and the left armrest 9b are both operated at normal speeds so that the right armrest 9a and the left armrest 9b reach the target positions at the same time.

The adjusting unit 43 adjusts the positions of the left and right armrests 9 by repeatedly executing the processes of steps 101 to 109. That is, the adjusting unit 43 recognizes the position of the armrest 9 based on the detection signals S2 to S5 input from the second detection units 25, 28, 36, 39 provided on the armrest 9, and the armrest 9 is at the target position. The armrest 9 is operated so as to reach. The adjustment in the slide direction and the adjustment in the height direction of the armrest 9 may be performed at the same time or in order.

When the difference K1 between the current position and the target position of the armrest 9 does not exceed the threshold value in step 105, the adjusting unit 43 stops the motors 23, 26, 34, 37 of the armrest 9 in step 110. As a result, the operation of the armrest 9 is stopped, and the position adjustment of the armrest 9 is completed.

Therefore, the position adjustment of the armrest 9 can be simplified.

(2) The detection unit (first detection unit 17) detects the reclining operation of the seat 2 as the seat operation. The adjusting unit 43 adjusts the state of the armrest 9 so that the armrest 9 has a mode corresponding to the reclining state based on the detection signal S1 of the detection unit (first detection unit 17) that detects the reclining mode. .. Therefore, the armrest 9 can be automatically adjusted to the optimum state according to the reclining state.

(3) When the detection unit for detecting the seat operation is the first detection unit 17, the adjustment unit 43 has a detection signal S2 input from the second detection units 25, 28, 36, 39 for detecting the state of the armrest 9. Based on ~ S5, the difference between the left and right armrests 9 is monitored, and the adjustment for correcting the difference is executed. Therefore, for example, when the left and right armrests 9 are present on the seat 2, these armrests 9 can be set at positions where the left and right armrests are less unbalanced.

Note that this embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

-As shown in FIG. 6, the adjusting unit 43 may start the movement of the armrest 9 at a low speed when the armrest 9 is operating. In this case, since the armrest 9 is prevented from suddenly moving, it is possible to prevent the armrest 9 from being pinched. In addition, it is possible to give a feeling of hospitality to the movement of the armrest 9.

As shown in FIG. 6, when the armrest 9 is operating and the armrest 9 approaches a predetermined distance with respect to the target position, the adjusting unit 43 decelerates the armrest 9 to shift to a low speed, and then moves the armrest 9 to the target position.

Therefore, the armrest 9 can be adjusted to a position suitable for the physique and preference of the occupant. Further, the operation unit 47 is not limited to being provided on the seat 2, and may be arranged at another place in the vehicle.

-As shown in FIG. 9, the seat control device 3 may include a disembarkation determination unit 48 that determines whether or not an occupant disembarks from the vehicle 1 on which the seat 2 is mounted. When the disembarkation determination unit 48 determines that the occupant will disembark, the adjusting unit 43 may evacuate the armrest 9 to a position that does not interfere with the disembarkation. Positions that do not interfere with getting off include, for example, a storage position of the armrest 9, a position that is flush with the seat cushion 6, and a retracted position in front of the storage position. In this case, since the armrest 9 does not get in the way when getting off, smooth getting off can be ensured.

As shown in FIG. 10, when the adjusting unit 43 detects the operation intention of the armrest 9 based on the user operation of the non-switch operation, the adjusting unit 43 may execute at least one of pushing out and retracting the armrest 9. Non-switch operation user operations include, for example, voice operation, gesture operation, sensor operation, and the like.
