Description

Electric seat operation method for vehicle {Memory seat processing method using car}

The present invention is a relay (relay) for operating a plurality of motors each used in the seat operation in a vehicle electric seat having a memory function for adjusting the position and posture according to the user by storing the position and posture of the seat previously set by the user It is a technology related to the operation of the vehicle electric seat to control the electric seat effectively while reducing the number.

Recently, due to the demand for increased user convenience, vehicle electronics have been rapidly progressing. In addition, the seat of the vehicle is also implemented to change the posture and movement using a motor beyond the conventional mechanical operation. In addition, a memory function that stores the position and posture of the sheet preset by the user for each user and adjusts the position and posture according to the user with a simple operation when changing the user is applied. The electric seat controller to realize this function can basically move the whole seat forward / backward or the backrest forward / backward. It is possible to adjust the Front Height Up / Down and Rear Height Up / Down. To this end, a control device that can properly control the motor used for position and attitude adjustment is essential.

Most seat control devices with memory functions applied to conventional vehicles operate motors for slide, recline, front height, and rear height control, respectively, used for seat operation. In this way, the motor is rotated forward or reverse depending on the situation to change the position and attitude. In order to change the rotation direction of the motor, a lot of relays are generally used. In order to control the motors separately, as shown in FIG. 1, at least eight 1-pole relays (11 to 18), as shown in FIG. Four 2-pole relays (31-34) are required.

Front Height Motor to adjust, 24 indicates Rear Height Motor to adjust rear height of seat, F for Forward, B for Backward ), U is Up, D is Down,

Is the + pole of the power source,

Denotes the negative poles of the power source.

As is well known, the conventional seat control apparatus uses a relay configured for each motor to control the slide, the recline, the front height, and the rear height direction of the seat.

For example, in order to advance the electric seat, the first relay 11 shown in FIG. 1 is turned off (relay switch is connected to contact point 1), and the second relay 12 is turned on (relay switch is connected to contact point 2). ) The slide motor 21 is rotated forward (F) to move the electric seat in the forward direction. To reverse the electric seat, turn on the first relay 11 (relay switch connected to contact 2), turn off second relay 12 (relay switch connected to contact 1), and reverse slide motor 21. Rotate (B) to move the power sheet in the reverse direction. In the case of FIG. 2, the operation of the relay is controlled in the same manner as the relay of FIG. 1.

In this manner, the recline motor 22, the front height adjustment motor 23, and the rear height adjustment motor 24 are individually driven to change the position and posture of the electric seat.

In this case, only one motor operates when the user operates the seat operation switch for each slide, recline, front height, and rear height, or when moving the seat for interlocking operation. The four motors are used at the same time only when the position and posture data stored in the file must be reproduced and moved in the direction of slide, recline, front height, and rear height. In general, most car drivers are the same, so the frequency of four motors controlled at the same time is not very high. Here, the position or posture data set for each user does not have a large difference, so even if the position and posture change sequentially, only a short time is required so that the user does not feel inconvenience.

On the other hand, the relay used in the conventional electric seat should have a rated current of 20A or more in consideration of the current of 10A or more that flows at the time of starting the motor or when the motor is fixed mechanically, and is used in a vehicle, so it has reliability with environmental resistance. It must be a high product. Therefore, the relay must use a relay that is expensive compared to the general electronic components, which results in a disadvantage that the ratio of the total cost of the relay to the total cost of the control device is high.

In conclusion, in a situation where it is necessary to use an expensive relay, there is a need for an electric seat control technique for controlling all motors in an independent or simultaneous combination while minimizing the number of relays.

Accordingly, the present invention is proposed to meet the demand for efficiently controlling the motor while minimizing the number of relays, as well as eliminating the problems occurring in the conventional vehicle electric seat control apparatus as described above.

The problem to be solved by the present invention is to provide a vehicle electric seat operating method to reduce the cost by reducing the number of relays required for the electric seat control.

Hereinafter, described in detail with reference to the accompanying drawings a preferred embodiment of the present invention. In the following description, well-known functions or constructions are not described in detail since they would obscure the invention in unnecessary detail.

Figure 3 shows a configuration for the control device for a motor vehicle according to the present invention, a slide motor 131 for moving forward and backward the electric seat, a front height adjustment motor 132 for adjusting the height of the front portion of the seat, A recline motor 133 for adjusting the inclination of the seat back, a rear height adjusting motor 134 for adjusting the height of the rear portion of the seat, a rotation direction determining unit 110 and a motor driving unit 120 are included.

Although not shown in the drawing, the control device for the vehicle electric seat includes a single and simultaneous combination relay control data in the internal memory, and adds the single and simultaneous combination relay control data embedded in the memory in response to the user's seat operation switch. It is preferable to further include a control unit for generating a relay control signal to the rotation direction determination unit 110 and the motor driving unit 120, respectively.

The rotation direction determiner 110 includes a slide motor 131 for moving the memory sheet forward and backward, a recline motor 133 for adjusting the inclination of the seat back, and a height of the front portion of the seat. The front height adjustment motor (132) for adjusting the (Front Height Motor) 132, the rear height adjustment motor (Rear Height Motor) for adjusting the height of the rear portion of the seat (Rear Height Motor) performs a function for determining the rotation direction.

The rotation direction determination unit 110 includes a first relay R1 and a second relay R2 for determining the rotation direction of each of the motors 131 to 134 as reverse rotation or forward rotation.

The motor driver 120 selectively drives the respective motors 131 to 134 by selectively supplying driving power to the respective motors 131 to 134 in association with the rotation direction determiner 110. Or drive in a simultaneous combination.

The motor driving unit 120 includes: first and second relays R3 and R6 for controlling driving of the slide motor 131 and the front height adjustment motor 132; Third and fourth relays R4 and R5 for controlling the driving of the recline motor 133 and the rear height adjustment motor 134 are included.

As is well known, the relays R1 and R2 of the rotation direction determining unit 110 control the power supply to determine the forward and reverse rotations of the respective motors 131 to 134, and the relays of the motor driving unit 120 R3, R4, R5, and R6 determine which of each of the motors 131 to 134 are to be powered according to their optional combination.

Any one of a plurality of operation switches provided in the seat operation switch, for example, four single seat operation switches for individually operating four motors and a memory control operation switch for operating all four motors When operating the operation switch of, the controller recognizes this and selectively withdraws the single and simultaneous combination relay control data stored in the internal memory to operate the motor.

For example, when a user manipulates any one of four single sheet manipulation switching of the sheet manipulation switches, the single relay control data stored in the memory is fetched to individually control only the corresponding motor. On the contrary, when the user operates the memory control operation switch for operating all four motors of the seat operation switch, the controller extracts the single relay control data and the simultaneous combination relay control data stored in the memory, and then the priority of the motor control. In the state of setting the relay control data of any one of the two relay control data is selected by controlling all the motors sequentially or by controlling a combination of two motors at the same time by a simultaneous combination.

Simultaneous combination in the above means a relay combination for controlling two motors at the same time according to the situation.

In [Table 1] [Table 2], the relay OFF state means a state in which the relay switch is connected to the first contact point, and the ON state means a state in which the relay switch is connected to the second contact point. .

The control unit draws out the single / simultaneous combination relay control data as described above from the memory to appropriately control the corresponding relay. For example, the user may use a single sheet operation switch called slide forward to advance the memory sheet. When operated, the controller fetches a single relay control data as shown in [Table 1], among which relay control R1-OFF, R2-OFF, R3-OFF, R4-OFF, R5-OFF, and R6-ON. Data is extracted to control the relay.

By such relay control, the relays R1 and R2 of the rotation direction determining unit 110 are connected to the contact 1, and the relays R3, R4 and R5 of the motor driving unit 120 are connected to the contact 1. Relay R6 is connected to contact 2.

)단자에 접속되므로, 슬라이드 모터(131)는 공급되는 전원에 의해 정 회전을 하게 되며, 이러한 정 회전에 의해 메모리 시트가 앞으로 이동하게 된다.By driving such relays, the + power supply (

) Is supplied to the slide motor 131 after the relay (R1) (R3), the other terminal of the motor 131 through the relay (R6) (R2) -power (

Terminal), the slide motor 131 rotates forward by the power supplied, and the memory sheet moves forward by the forward rotation.

Even when a single operation of another sheet operation switch is performed, the operation of the motor is performed based on the single relay control data in Table 1, and the position and attitude of the memory sheet are changed by the operation of the motor.

In addition, when a user operates two or more single sheet operation switches simultaneously, the control unit turns off the operation states of all the relays R1 to R6 so as to control no motor to operate.

On the other hand, when the user operates the memory control operation switch, that is, when all four motors are to be operated based on the relay control data stored in advance for each user, the control unit prioritizes to sequentially control the operation of all the motors. Set.

In this case, the relay control data stored in advance for each user is uniquely stored in the memory by the controller when the user selects his own unique number in advance and requests to store it while the user adjusts the position and posture of the seat that is optimal for driving. This can be implemented by storing relay control data for a number. Alternatively, if you press the save switch of the memory sheet in the current state, the serial number is assigned according to the save order and the relay control data of the current state is saved.After that, when the user selects the memory sheet operation switch and selects the unique number, It is also possible to automatically control the position and attitude of the memory sheet by extracting the stored relay control data.

Priority can be set by various methods, but preferably, when all the motors are sequentially controlled using a single relay control data as shown in [Table 1], all motors are stopped. Is the highest priority, then slide forward (F), slide backward (B), recline forward (F), recline backward (B), front height above (U), front height below (D), rear height Set it in the same order as above (U), below the rear height (D).

And according to the priority as described above to control the four motors individually and automatically control the electric seat in the position and posture stored by the user.

In addition, if a single sheet operation switch is operated in the middle of automatically controlling the electric seat as described above, the automatic control operation currently being performed is terminated and the operation is immediately controlled in response to the manual sheet operation switch.

On the other hand, the present invention can control two motors at the same time depending on the situation.

In general, when the user sets the position and posture of the seat, a tall driver adjusts the seat position and the back of the seat back and below the height of the seat in front of and behind the seat. In most cases, the backrest is adjusted forward and the height of the seat front and back is adjusted upward. Therefore, priorities are set as shown in [Table 2] by using these drivers' habits or relativity.

That is, as shown in [Table 2], slide forward and recline forward, slide forward and rear height, slide backward and recline backward, slide backward and backward height, recline forward and front height, and recline Priorities will be set in the order of reverse and forward height, above and above height and above, behind and below height.

When all the motors are operated by reproducing the relay control data stored in the memory for each user, analyze the relay control data reproduced for each user to check whether there is a need to operate the motor in a simultaneous combination, and then operate the motor in the simultaneous combination. If there is no case, only the single relay control data as shown in [Table 1] is used to control all the motors individually in order of priority.

On the other hand, when there is a case of operating the motor in the simultaneous combination, using the simultaneous combination relay control data as shown in Table 2 to sequentially control the two motors at the same time according to the priority.

For example, the relays R1, R2, R3 are turned off (connected to contact 1) and the relay R6 is turned on (connected to contact 2) for the slide forward operation. Or selectively turns on or off the relay R5.

Then, the slide motor 131 operates in the forward direction and at the same time the recline motor 133 operates in the forward direction or the rear height adjustment motor 134 operates in the upward direction.

Therefore, when controlling each motor using the simultaneous combination relay control data as shown in [Table 2], the forward movement of the seat and the backrest can be moved forward and the reverse movement of the seat backward and the backrest is possible at the same time. In addition, the height of the front and rear seats can also be adjusted at the same time.

This operation of two motors at the same time can be similar to the method of driving four motors at the same time in the conventional electric seat control device, but the number of relays and peripherals can be reduced, reducing the design cost of the electric seat control device Not only that, but also the size and configuration of the device can be simplified. In addition, in consideration of a state in which the user does not feel uncomfortable, since the two motors are operated in a combination at the same time, there is an advantage of minimizing the inconvenience of the user due to the simultaneous operation of the motor.

4 is a flowchart illustrating a method for operating an electric seat for a vehicle according to the present invention, where S represents a step.

As shown therein, detecting the input state of the sheet operation switch (S101); When a single sheet operation switch is input as a result of the detection, extracting single relay control data from a memory to selectively control the plurality of motors (S103 to S105); A step (S017 to S109) system for extracting single and simultaneous combination relay control data from a memory for controlling all of the plurality of motors when a memory control operation switch is input as a result of the detection; Setting priorities for controlling the plurality of motors in an alternative or simultaneous combination (S111); Check whether there is a motor to be controlled by the simultaneous combination, and if there is no motor to be controlled by the simultaneous combination, sequentially controlling all the plurality of motors according to the priority set using the single relay control data. Steps S113 to S115; If there is a motor to be controlled by the simultaneous combination, step S117 of controlling all the plurality of motors sequentially according to the priority set using the simultaneous combination relay control data.

In the vehicle electric seat operating method according to the present invention thus achieved, the control unit detects the operation state of the seat operation switch as in step S101. As a result of this detection, if the sheet operation switch is not operated, the current state is maintained. Otherwise, if the sheet operation switch is operated, it is checked in step S103 whether a single sheet operation switch is operated.

Here, as is well known, a single seat operation switch such as slide forward / reverse, recline forward / reverse, front height up / down, rear height up / down, and the like, for controlling each motor individually, and in advance, A memory sheet operation switch for controlling all motors according to the stored relay control data; in addition to these operation switches, a memory sheet storage switch for storing a memory sheet position and attitude data of a current state, a plurality of stored memory sheet position and attitude data It includes a unique number selection or input switch for selecting only specific data.

As a result of the check, when a single sheet operation switch is operated, the control proceeds to step S105, where the single relay control data as shown in [Table 1] corresponding to the corresponding operation switch is extracted from the internal memory, and the motor is extracted with the single relay control data. Selectively controlling 131 to 134 to perform a corresponding operation. Here, the operation of selectively controlling the motor in response to the relay control data is performed in the same manner as the description of FIG. 3.

Next, when the single sheet operation switch is not operated as a result of the check, the flow advances to step S107 to confirm whether the memory control operation switch is operated. As a result of this check, when the memory control operation switch is not operated, the process moves to the first step S101 in which the operation state of the sheet operation switch is detected, where the motor control operation is performed even when a plurality of single sheet operation switches are operated simultaneously. Without performing, the first step moves to step S101.

On the other hand, when the memory control operation switch is operated, the flow advances to step S109 to retrieve previously stored single relay control data and simultaneous combination relay control data for controlling all of the plurality of motors 131 to 134 in the memory. Of course, the relay control data to be withdrawn is relay control data corresponding to the user.

Next, in step S111, priorities for controlling all the motors 131 to 134 are set. Here, the priority is set based on the relay control data of the user and the priorities described in [Table 1] and [Table 2].

If the priority is set, go to step S113 to check whether there is a motor to operate simultaneously. If there is no motor to operate simultaneously, go to step S115 to use the single relay control data shown in [Table 1] and set the above. According to one priority, all the motors are controlled by sequentially controlling the plurality of motors 131 to 134 individually.

On the other hand, if there is a motor to operate simultaneously, that is, if the motor is operated in a simultaneous combination, go to step S117 and use the simultaneous combination relay control data as shown in [Table 2]. The motors 131 to 134 are sequentially controlled. In other words, according to the relay control data as shown in [Table 2], the forward movement of the seat and the backrest can be moved simultaneously, and on the contrary, the backward movement of the seat and the backrest can be simultaneously moved. Simultaneous operation is possible.

Although not shown in the drawing, if a single sheet operation switch is operated while automatically controlling the electric seat using relay control data, the automatic control operation is terminated and the operation is immediately controlled corresponding to the manual sheet operation switch. .
