Description

  The present invention relates to a seat position control device used for a vehicle seat, and more particularly to a seat position control device that moves an electric seat in a short time to a position where the passenger can easily get on and off when the passenger gets on and off.

Conventionally, an electric seat that moves the position of the seat back and forth or changes the height of the seat surface by a motor or the like has been used so as to be optimal for driving of an occupant. There is also known an electric seat that stores a seat position set in advance by an occupant and can be returned to the stored position even when the seat position is changed. Also, in such an electric seat, a method of moving the seat rearward is known in order to secure a space for moving the legs and facilitate getting on and off when the passenger gets on and off.
For example, in Patent Document 1, a driving position and a boarding / alighting position are set. When the passenger gets on and off, the seat is moved backward to a predetermined initial position (boarding / alighting position), and when the seat belt is mounted, the seat is moved to a driving position (driving position). The invention of a seat position control device that moves forward is disclosed.

JP 2007-196948 A

As described above, there is known a seat position control device that stores a driving position (driving position) of an electric seat preset by a vehicle occupant and moves the electric seat to the driving position at the start of driving. In the seat control method described in Patent Document 1, it is possible to move the seat to a predetermined rear position (boarding / exiting position) before the driver gets on or when the driver gets off.
However, normally, the driving position of the vehicle seat differs depending on the occupant's physique, and the boarding / exiting position of the seat on which the occupant can easily get on and off also differs depending on the occupant's physique. For this reason, there has been a problem that if the boarding position is made constant, for example, the vehicle seat is moved to the rear end during boarding / exiting, the position is not optimal for boarding / exiting. In addition, depending on the occupant's physique, the seat may be moved to a certain boarding / exiting position, even though the seat is moved slightly backward to achieve the optimal position for getting off. There was a problem that an extra waiting time occurred until completion.

  The present invention has been made in view of the above-described situation, and an object of the present invention is to provide a seat position control device that moves an electric seat to an optimal position where the passenger can easily get on and off when the passenger gets on and off. .

In order to solve the above problem, the first invention is a seat position control device that adjusts the position of an electric seat when an occupant gets on and off the vehicle, and detects the current position of the electric seat. Means, a position adjusting means for driving the electric seat to adjust its position, a driving detecting means for detecting the driving state of the vehicle, and when the driving detecting means detects that the vehicle is in a driving state Further, based on the position of the electric seat detected by the position detecting means, an getting-on / off position setting means for setting and storing an optimum getting-on / off position suitable for occupant getting-on / off is detected, and stoppage of the vehicle is detected by the driving detecting means. When this is done, the boarding / exiting position control is performed such that the optimum boarding / alighting position stored by the boarding / alighting position setting means is read and the electric seat is moved to the optimum boarding / alighting position by the position adjusting means. And summarized in that comprising a stage, a.
According to a second aspect of the present invention, in the first aspect, the boarding / alighting position setting means estimates the physique of a seated occupant based on the detected current position of the electric seat, and the optimal boarding / alighting position corresponding to the estimated physique The gist is to set.
According to a third aspect of the present invention, in the first and second aspects of the invention, the getting-on / off position setting means is detected by the position detection means after the driving detection means detects that the vehicle is in a driving state. The gist is to set the optimum boarding / alighting position when the position of the electric seat does not change for a predetermined time or more.
According to a fourth aspect of the present invention, in any one of the first to third aspects, the getting-on / off position setting means detects the position of the seat surface height of the electric seat by the position detection means, and based on the detected position. The gist is to set the optimum boarding / alighting position.
According to a fifth aspect of the present invention, in any one of the first to fourth aspects, the driving state detected by the driving detecting means includes one or more of an ignition switch state and a shift lever position. To do.

  According to the seat position control device of the present invention, position detecting means for detecting the current position of the electric seat, position adjusting means for driving the electric seat to adjust its position, and driving detection for detecting the driving state of the vehicle. And a boarding / alighting position setting means for setting and storing an optimal boarding / alighting position suitable for boarding / alighting of a passenger based on the position of the electric seat when it is detected that the vehicle is in a driving state; And a boarding / alighting position control means for moving the electric seat to the stored optimum boarding / alighting position, so that when the passenger gets on and off, the optimal boarding / alighting position set based on the seat position during operation of the passenger is obtained. The electric seat can be moved to provide a necessary and sufficient space for passengers to get on and off. In addition, since the electric seat is not moved to a certain position such as the rear end of the moving range when getting on and off, it is possible to reduce the extra movement and movement time of the electric seat, and the occupant can get on and off without extra waiting time. it can.

  When the boarding / alighting position setting means estimates the physique of the seated occupant based on the detected current position of the electric seat and sets the optimal boarding / alighting position corresponding to the estimated physique, The electric seat is moved to the optimum boarding / alighting position according to the occupant's physique. For example, when it is estimated that the occupant is a small physique from the seat position during driving, the seat seat surface when getting off is greatly reduced, and when the occupant is estimated to be a large physique, The height of the seat surface when getting off can be kept appropriate. Thereby, according to the occupant's physique, the electric seat can be moved to a position where the toes are easy to move when getting on and off, and the getting on and off operation does not interfere with the steering wheel or the like.

  When the position of the electric seat detected by the position detection means does not change for a predetermined time after the boarding position setting means is detected by the driving detection means that the vehicle is in a driving state, the optimum boarding position is determined. In the case of setting, the seat position in a state where the seat is adjusted to the optimum driving position by the occupant and is stably driven can be acquired. And since a passenger | crew's physique is estimated from the seat position and the optimal boarding / alighting position is calculated | required based on the physique, the seat position at the time of boarding / alighting can be set more appropriately.

  When the boarding / alighting position setting means detects the position of the seat height of the electric seat by the position detection means and sets the optimum boarding / alighting position based on the detected position, the occupant changes his / her posture when getting on / off The optimal boarding / alighting position can be set so as to reduce the burden on the occasion and prevent the knee or the like from hitting the handle or the like.

  When the driving state detected by the driving detection unit includes one or more of the ignition switch state and the shift lever position, it can be reliably determined whether or not the vehicle is in a driving state. Therefore, it is possible to make the timing of detecting the seat position in the operating state and moving the seat to the getting-on / off position more appropriate.

The items shown here are for illustrative purposes and exemplary embodiments of the present invention, and are the most effective and easy-to-understand explanations of the principles and conceptual features of the present invention. It is stated for the purpose of providing what seems to be. In this respect, it is not intended to illustrate the structural details of the present invention beyond what is necessary for a fundamental understanding of the present invention. It will be clear to those skilled in the art how it is actually implemented.

(Configuration of seat position control device)
The seat position control device according to the present embodiment is a device that adjusts the position of the electric seat when an occupant gets on and off the vehicle. As illustrated in FIG. 1, the position detection means 3 of the electric seat 2, the electric seat 2 position adjustment means 4, operation detection means 5, entry / exit position setting means 6, and entry / exit position control means 7.

  The use and type of the electric seat 2 are not particularly limited, and the seat position control device 1 targets an electric seat for an arbitrary vehicle. The seat position control device 1 can be suitably used particularly for an electric seat provided as a driver seat, a passenger seat, a rear seat, or the like of an automobile. Such an electric seat is appropriately provided with a lifter mechanism that moves the seat surface up and down and back and forth, a slide mechanism that moves the seat in the front-rear direction of the vehicle, a reclining mechanism that changes the angle of the backrest, and the like. It can be adjusted by power such as.

  The position of the electric seat 2 that is adjusted by the seat position control device 1 can be one or more positions for making it easy for passengers to get in and out of the adjustable portion provided in the electric seat 2. For example, as an object to be adjusted by the seat position control device 1, the vertical position (seat surface height) of the seat surface with respect to the passenger compartment floor surface can be given. Moreover, the seat position (front-rear position) in the front-rear direction can be given. In addition, the position of the electric seat 2 can include an inclination of the seat surface, a reclining angle, and the like. The seat position control device 1 may be configured to control the position of only one of these adjustment portions of the electric seat 2 or may be configured to control two or more positions.

  The position detection means 3 is a means for detecting the position of the electric seat 2 that is to be adjusted by the seat position control device 1. The specific configuration can be arbitrarily selected. For example, the position detection may be performed by providing a position sensor on the electric seat 2, or a motor for moving the electric seat 2 is provided with a rotation sensor, and the position of the electric seat is calculated in combination with the position sensor. Also good. In addition, position detection means generally provided on the electric seat can be used.

The position adjusting means 4 includes a drive circuit and a control circuit such as a motor for driving various adjustment portions of the electric seat 2 and can be configured to be used for a normal electric seat.
The electric seat is generally provided with a switch for manual operation, and the occupant can adjust the front and rear position of the seat, the seat surface height, and the like using the switch. The adjustment of the seat position by the manual operation switch may be incorporated in the position adjusting means 4 or the electric seat 2 may be driven separately.

  The driving detection means 5 is means for detecting whether or not the vehicle is in a driving state. The driving state is intended to mean a state where the vehicle is being driven or a state where the vehicle can be driven. When the vehicle is in a driving state, it can be determined that the occupant is seated at an appropriate seat position (driving position). Further, when the vehicle is stopped and the occupant removes the seat belt or opens the door, it can be determined that the occupant gets off the vehicle. Useful information for this determination includes the ignition switch status, shift lever position, seat belt installation, vehicle speed, door lock status, door open / close, steering wheel tilt status, etc. Can do.

Among the above, the driving state detected by the driving detection means 5 can include one or more of the state of the ignition switch and the position of the shift lever. For example, if the ignition switch is on, it can be determined that the vehicle is in a drivable state. Further, when the position of the shift lever is other than parking or neutral, it can be determined that the vehicle is in operation or is ready for operation.
The driving detection means 5 may be configured to detect the various states described above by including various sensors, or may be configured to receive information on the states from an external device (ECU).

  The getting-on / off position setting means 6 is based on the position of the electric seat 2 detected by the position detecting means 3 when the driving detecting means 5 detects that the vehicle is in a driving state, and is an optimum getting-on / off position suitable for passenger getting on / off. Is means for setting and storing. The optimum getting-on / off position is the position of the electric seat 2 in which a space around the seat is secured so that the occupant can move without difficulty to get on and off the vehicle within the movable range of the electric seat 2, and the physique of the occupant, the electric seat 2, the seat surface height of the electric seat 2, the distance between the electric seat 2 and the steering wheel, the tilt state of the steering wheel, and the like. Moreover, since this optimal boarding / alighting position is not normally located at one end within the movable range of the electric seat 2, the movement amount and the movement time can be shortened as compared with the case of moving to the one end during boarding / alighting.

  For this reason, the getting on / off position setting means 6 is configured to detect the current position (driving position) of the electric seat 2 by the position detecting means 3 when the driving detecting means 5 detects that the vehicle is in a driving state. . From the driving position of the electric seat 2, the physique of the occupant can be estimated. Examples of the occupant's physique include height, leg length, and sitting height. When the occupant takes a driving posture, the driving position is related to the physique of the occupant because the seat position is adjusted according to the distance to the pedal and the distance to the steering wheel. Therefore, the getting on / off position setting means 6 can be configured to estimate the physique of the occupant based on the seat position (seat surface height, front / rear position, etc.) when the occupant takes an appropriate driving posture.

  And the boarding / alighting position setting means 6 is configured to set (derived) the optimal boarding / alighting position corresponding to the estimated occupant's physique and store it. In other words, the boarding / exiting position setting means 6 determines the seat height of the electric seat 2 so that the occupant's feet can touch the floor surface of the vehicle and can be stepped on without being overwhelmed. The seat height and front / rear position that secures a space where the legs can move without being blocked by the steering wheel are derived as the optimum boarding / alighting positions. The optimal boarding / alighting position can be a position that differs for each application of the electric seat 2. This is because the surrounding space differs depending on the driver's seat, the passenger seat, the rear seat, etc., and the in-vehicle facilities that affect the passenger's getting-on / off operation also differ.

The method for estimating the occupant's physique and the method for determining the optimum boarding / alighting position from the physique are not particularly limited. For example, the seat position in the actual driving state and at the time of getting on and off for passengers of various physiques in advance, and conversion formulas, correspondence tables, etc. for deriving the optimum getting on and off position from the driving position based on the investigation result Can be created. The boarding / alighting position setting means 6 can be configured to derive the optimal boarding / alighting position from the seat position in the driving state by referring to the correspondence table or the like.
The boarding / alighting position setting means 6 can be configured, for example, to detect the seating surface height of the electric seat 2 and derive the optimal boarding / alighting position from the detected position of the seating surface height. Further, at least one position of the seat height of the electric seat 2 and the front / rear position may be detected, and the optimum boarding / alighting position may be set based on the detected position.

  The boarding / alighting position setting means 6 is the optimum boarding / alighting position when the position of the electric seat detected by the position detection means 3 does not change for a predetermined time after the driving detection means 5 detects that the vehicle is in a driving state. Can be configured to set. Accordingly, it is possible to prevent position detection when the occupant manually adjusts the position of the electric seat.

  The boarding / alighting position control means 7 reads out the optimum boarding / alighting position stored by the boarding / alighting position setting means 6 when the driving detection means 5 detects that the vehicle has stopped driving, and the position adjusting means 4 sets the electric seat 2 to the optimum boarding / alighting position. It is a means to move.

The position detection means 3, the position adjustment means 4, the operation detection means 5, the boarding / alighting position setting means 6 and the boarding / alighting position control means 7 described above may be configured only by hardware or using a microprocessor or the like. It may be configured by hardware and software. Preferably, it can be configured by a CPU (memory, ROM, RAM), a microcontroller (microcomputer) including an input / output circuit, and peripheral circuits. However, the present invention is not limited to this, and it may be configured by a programmable logic circuit, a gate array, or other logic circuits.
The seat position control device 1 is supplied with necessary power from a power source (not shown). For example, the seat position control device 1 and the electric seat 2 can be supplied with power from a vehicle battery.

(Operation and control of seat position control device)
2 and 3 show examples of the electric seat 2 provided in the driver's seat of the vehicle. The electric seat 2 of this example can adjust the position of the seat in the front-rear direction and the height of the seat surface 21.
FIG. 3 is a diagram for explaining the operation of the electric seat 2 by the seat position control device 1. The height from the lower end 22 to the upper end 23 of the seat surface 21 of the electric seat 2 is defined as a seat surface height H. Further, the front-rear position W of the seat is represented by the distance W from the front end 24 of the movable range in the front-rear direction of the electric seat 2 to the front end of the seat surface 21. In FIG. 3, the position of the electric seat 2 (seat surface height H, front / rear position W) indicates an appropriate driving position of a certain occupant, and the position of the electric seat 2 ′ (seat surface height H ′, front / rear position). W ′) is a boarding / alighting position that is an optimum boarding / alighting position, and a space is secured for the occupant so that the leg can be moved without being blocked by the steering wheel 8. Note that one end of the movable range of the electric seat is located further rearward than the position of the electric seat 2 ′.

At the start of driving of the vehicle, the occupant adjusts the position of the electric seat 2 in accordance with his / her physique and sets the position to the optimum position (driving positions H and W). The movement to the driving position may be performed automatically by an occupant by operating a switch manually or by a separate system.
This operating position (H, W) can be detected by the position detecting means 3. The detection of the driving position is preferably performed after the adjustment by the occupant at the start of driving or the like is completed. For this reason, the boarding / alighting position setting means 6 can detect the driving position after confirming that the position of the electric seat does not change for a predetermined time or more after the vehicle is ready for driving.

The getting-on / off position setting means 6 detects the seat surface height H, the front-rear position W, etc. at the driving position by the position detection means 3. Then, the occupant's physique is estimated based on the position. For example, FIG. 4 shows a graph for estimating the height (physique) of the occupant from the seat height H. The vertical axis of figure represents the seating surface height H, base H ₀ represents a suitable seat surface height during operation in passenger standard physique. Seat surface height H of the electric sheet, in this example, 35 mm approximately upward from the base point H _0, is movable in a range of about 25mm down. The horizontal axis of the figure represents the occupant's physique (height).
Usually, when the occupant's height is lower than the standard seat surface height H is positioned higher than the base point H ₀ of the driving position, when the height is higher than the standard seating surface height H base H ₀ Lower position. Such a relationship can be obtained by conducting experiments on a large number of passengers. By storing the general relationship between the seat surface height H and the occupant's physique as a table in the seat position control device 1 in advance, the boarding / exiting position setting means 6 uses the table to sit. The physique of the occupant can be estimated from the surface height H. In order to estimate the physique, in addition to the seat height H, the front-rear position W or the like may be used, or the physique may be estimated by combining them.

FIG. 5 illustrates the relationship between the occupant's physique and the optimal boarding / alighting position in the same electric seat as in the previous figure. The vertical axis in the figure represents the seat surface height H ′ at the boarding / exiting position, that is, the optimum boarding / exiting position, and the horizontal axis represents the physique (height) of the occupant. The base point H ₀ is the same as in the previous figure.
Usually, when the height of the occupant is lower than the standard, it is appropriate to set the seat height H ′ at the boarding / alighting position to a position that is significantly lower than the base point H ₀ . In this example, when the height is less than 130 cm, the seat surface height H ′ is the lower end of the movable range of the electric seat. On the other hand, in the present electric seat, when the height of the occupant is higher than the standard, it is appropriate to set the seating surface height H ′ to a position slightly lower than the base point H ₀ . Such a relationship can be obtained by conducting experiments on a large number of passengers. By storing the general relationship between the occupant's physique and the optimum boarding / alighting position as a table in the seat position control device 1 in advance, the boarding / exiting position setting means 6 can determine the occupant's physique from the estimated occupant physique. The optimal boarding / alighting position (seat surface height H ′) can be obtained using the table. In this example, the seat surface height H ′ is set as the optimum boarding / alighting position, but the front / rear position W ′ or the like may be obtained, or the optimum boarding / alighting position may be set by combining them. The boarding / alighting position setting means 6 stores the set optimal boarding / alighting position in a memory in the seat position control device 1.

  4 and 5, the method of estimating the occupant's physique from the driving position and then obtaining the optimal boarding / exiting position from the physique has been described. Needless to say, the optimal boarding / exiting position can be derived directly from the driving position. Yes.

  The driving state of the vehicle can be constantly monitored by the driving detection means 5. And when driving | running | working of a vehicle is complete | finished, an electric seat is moved to the optimal boarding / alighting position. For this reason, when the driving detection means 5 detects that the driving of the vehicle is finished (driving stop), the boarding / alighting position control means 7 reads out the optimum boarding / alighting position stored by the boarding / alighting position setting means 6 from the memory. The electric seat 2 is moved to the optimum boarding / alighting position (H ′, W ′) by the adjusting means 4.

FIG. 6 is a flowchart illustrating an example of a control method in the sheet position control apparatus 1.
When the manual operation switch of the electric seat 2 is operated by the occupant when the operation is stopped (step S1), the height or the front / rear position of the seat surface 21 corresponding to the operation is changed by the motor (step S2). This process can be performed by the position adjusting means 4. Instead of the occupant's operation, the position of the electric seat may be automatically adjusted by a separate means.
Thereafter, the position of the shift lever, the state of the ignition switch, and the like are detected by the operation detection means 5 (steps S3 and S4). Here, if the position of the shift lever is in the parking (P) range or the ignition switch is not turned on, it is determined that the vehicle is not in operation (operation stop state), and the process returns to step S1. On the other hand, if the shift lever is not in the parking range and the ignition switch is turned on, it is determined that the vehicle can be driven (driving state), and the process proceeds to the next step S5.

  When the driving state is determined, the getting-on / off position setting means 6 waits for a predetermined time (for example, 30 seconds) to elapse after the electric seat is manually adjusted (steps S1 and S2) (step 30). S5). When the position of the electric seat is adjusted again during the predetermined time, the steps S1 to S5 can be repeated. That is, it is confirmed that the position of the electric seat does not change for a predetermined time or longer. This is because if the position of the electric seat is not adjusted for a predetermined time or longer while the vehicle is in a driving state, it is considered that the occupant has completed the adjustment and the electric seat has been adjusted to the optimum driving position.

  When the position of the electric seat has not changed for a predetermined time or more, the getting on / off position setting means 6 detects the current position of the electric seat (the seat surface height H, the front and rear position W, etc.) by the position detection means 3 (step S6). ). Then, the physique of the occupant is estimated based on the detected position (step S7), and the optimum boarding / alighting position (seat surface height H ′, front / rear position W ′, etc.) corresponding to the physique is obtained and stored (step S8). . As described above, the optimum boarding / alighting position can be obtained directly from the detected position.

Next, the seat position control device 1 monitors whether the driving state of the vehicle is continued. Whether or not the vehicle is in a driving state can be appropriately detected by the driving detection means 5. For example, the state of the ignition switch is monitored, and when the ignition switch is turned off, it can be determined that the driving of the vehicle has ended (step S9). In addition, in addition to the state of the ignition switch, the determination may be made by adding the presence / absence of the seat belt or the door opening / closing state.
When it is determined that the driving is finished, the boarding / alighting position control means 7 reads out the optimum boarding / alighting positions (seat surface height H ′, front / rear position W ′, etc.) stored by the boarding / alighting position setting means 6, and position adjustment means. The electric seat is moved to the optimum boarding / alighting position by 4 (step S10).

  By the above procedure, the electric seat can be moved to the position of the seat surface height H ′ at the optimum boarding / alighting position and the front-rear position W ′ when the operation is stopped. According to the occupant's physique, the toes can be brought into contact with the floor or the like when getting on and off, and the steering wheel 8 or the like can be placed in a position where the legs do not easily hit. In addition, since the electric seat is not moved uniformly to the rear of the movable range or the like, it is possible to make it possible to get on and off in a short time without the time spent for excessive movement.

The present invention is not limited to the embodiment described above, and various modifications can be made within the scope of the present invention depending on the purpose and application.
For example, the seat position control device for the present seat is not limited to the driver seat shown in the embodiment, but can be applied to a passenger seat or the like.
