Description

[0001] Cross-reference to related applications

[0002] This application claims priority and benefit to Korean Patent Application No. 10-2020-0144697, filed on November 2, 2020, with the Korean Intellectual Property Office, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This disclosure relates to apparatus and methods for detecting anti-pinch mechanisms in electric seats in vehicles, and more specifically, to techniques for detecting objects that are stuck or clamped during operation of electric seats in vehicles. Background Technology

[0004] Typically, vehicle seats used to maintain the occupant's seating and posture are configured to have a seat cushion and seat back positioned on a seat frame that moves along seat rails.

[0005] In addition, sliding and tilting mechanisms are located at the rear of the seat frame to maintain a posture suitable for the occupant's body shape.

[0006] When the occupant operates the lever or switch, this electric seat converts electrical energy into kinetic energy. When the sliding and tilting mechanisms are operated, the electric seat adjusts the tilt angle of the seat back by moving the seat forward or backward.

[0007] Recently, electric seats (or memory seats) have been widely used, allowing the seats to be operated by electric movement using switches, thus providing convenience for the driver.

[0008] However, because traditional electric seats lack anti-pinch functionality, even if a passenger's body or an object becomes trapped in the seat's sliding mechanism while the seat is moving, the seat may continue moving without stopping. This could result in injury to the passenger or damage to the object.

[0009] like Figure 1 As shown, although in conventional electric seat systems, the current output from the drive motor varies depending on the seat's position during operation, the reference current remains constant. Therefore, in section E1, where the difference between the reference current and the output current from the drive motor is small, erroneous reverse operation may occur during normal operation. Furthermore, in section E2, where the difference between the reference current and the drive motor's current value increases, clamping may go undetected. This could potentially lead to injury. Summary of the Invention

[0010] This disclosure is intended to solve the problems mentioned above in the prior art, while maintaining the advantages of the prior art.

[0011] One aspect of the present invention provides an apparatus and method for detecting anti-pinch effects in a power seat in a vehicle. The apparatus and method are capable of selecting optimized current level values ​​for each seat operating part by using Hall effect sensors pre-trained for current level values ​​for each seat operating part, rather than fixing the current level value used to detect objects pinched during operation of the power seat in the vehicle. The apparatus and method can use the selected current level value to detect pinched objects, thereby significantly improving the anti-pinch function.

[0012] Furthermore, another aspect of this disclosure provides an apparatus and method for detecting anti-pinch mechanisms in a power seat in a vehicle. This apparatus and method are capable of correcting the current level of the drive motor by using a Hall sensor to determine the effects of external environmental factors (lower temperature or higher voltage), and recalibrating the training position when the drive motor reaches its endpoint, thereby improving the reliability of current data for each position of the power seat.

[0013] The technical problems to be solved by this disclosure are not limited to those described above, and those skilled in the art to which this disclosure pertains should clearly understand from the following description any other technical problems that may be solved but not mentioned herein.

[0014] According to one aspect of this disclosure, an apparatus for controlling anti-pinch protection of a power seat in a vehicle is provided. The apparatus may include: a Hall sensor for sensing a position to which the power seat has moved; a drive motor for driving the movement of the power seat; a current sensor for measuring the level of current output from the drive motor; and a controller. The controller is configured to train a reference current level for determining anti-pinch protection relative to each position of the power seat using the Hall sensor and the current sensor, and to compare the current value measured by the current sensor relative to each position of the power seat with the trained reference current level for determining anti-pinch protection to determine anti-pinch protection.

[0015] According to one embodiment, the controller can flexibly calculate, through a learning algorithm, a reference current level for determining the anti-pinch function relative to each position of the electric seat.

[0016] According to one embodiment, the device may further include a storage device that stores data and algorithms executed by the controller. According to one embodiment, the controller can measure the level of the output current from the drive motor relative to the operating direction of the drive motor and at each position of the power seat. The controller can input the measured output current level into a learning algorithm to output trained current values. According to one embodiment, the controller can calculate a reference current level for determining the anti-pinch function relative to each position of the power seat by adding the average of the measured drive motor current values ​​and the average of the limiting current to the trained current values.

[0017] According to one embodiment, when an operating signal of the drive motor is received, the controller can determine whether a trained reference current level for determining anti-pinch protection relative to each position of the electric seat is stored in a storage device.

[0018] According to one embodiment, the controller can compare a trained current value with a current value obtained by measuring the level of the output current from the drive motor.

[0019] According to one embodiment, when the trained current value is greater than the current value obtained by measuring the level of the output current from the drive motor, the controller can determine that the current state is a normal state where anti-pinch does not occur, and operate the drive motor normally.

[0020] According to one embodiment, the controller can set the relative end position of the operating portion of the drive motor such that the operating portion is narrower than the portion of the drive motor that actually moves. The controller can determine whether the drive motor has reached one of the relative end positions when the drive motor stops.

[0021] According to one embodiment, when a limiting current is generated, the controller can determine whether the drive motor has reached one of the opposite positions.

[0022] According to one embodiment, when the drive motor reaches one of the positions at opposite ends, the controller can correct the end of the section used for training as the current position by measuring the current from the drive motor.

[0023] According to one embodiment, when the trained current value is equal to or less than the current value obtained by measuring the level of the output current from the drive motor, the controller can compare the trained reference current level for determining anti-pinch protection relative to each position of the electric seat with the current value obtained by measuring the level of the output current from the drive motor.

[0024] According to one embodiment, when the trained reference level for determining anti-pinch relative to each position of the power seat is less than the current value obtained by measuring the level of the output current from the drive motor, the controller can determine whether the pulse signal of the Hall sensor is normal.

[0025] According to one embodiment, when the pulse signal from the Hall sensor is normal, the controller can adjust the reference level used to determine the anti-pinch training relative to each position of the electric seat to a higher level.

[0026] According to one embodiment, when the pulse signal of the Hall sensor is abnormal, the controller can determine that clamping has occurred and perform control operations to stop the movement of the electric seat and perform reverse operations.

[0027] According to one aspect of this disclosure, a method is provided for detecting anti-pinch protection of an electric seat in a vehicle. The method may include: measuring the value of a current output from a drive motor driving the electric seat relative to each position of the electric seat; training an operation to determine a reference current level for anti-pinch protection relative to each position of the electric seat, the learning operation taking the measured value of the current output from the drive motor relative to each position of the electric seat as input; and comparing the measured value of the current output from the drive motor relative to each position of the electric seat with the trained reference current level for determining anti-pinch protection to determine anti-pinch protection.

[0028] According to one embodiment, training to determine the reference current level for anti-pinch protection relative to each position of the power seat may include flexibly calculating the reference current level for determining the anti-pinch protection relative to each position of the power seat through a learning algorithm.

These terms should not be interpreted as having an ideal or overly formal meaning unless clearly defined as having such a meaning in this application.

[0039] In the following text, reference will be made to Figures 2 to 7 The embodiments of this disclosure are described in detail.

[0040] Figure 2 This is a block diagram illustrating the construction of a device for controlling the detection of anti-pinch function of an electric seat in a vehicle according to an embodiment of the present disclosure.

[0041] refer to Figure 2 According to one embodiment of the present disclosure, a device 100 for controlling the detection of anti-pinch function of an electric seat in a vehicle includes a switch 110, a Hall sensor 120, a drive motor 130, a current sensor 140, a controller 150, and a storage device 160.

[0042] According to one embodiment of this disclosure, a device 100 for controlling the detection of anti-pinch mechanisms in a power seat in a vehicle can be implemented inside the vehicle. In this case, the device 100 for controlling the detection of anti-pinch mechanisms in a power seat in a vehicle can be integrally formed with the vehicle's internal control unit, or it can be implemented separately from the vehicle's internal control unit and connected to the vehicle's internal control unit via a separate connector.

[0043] Switch 110 can be operated by the user to automatically adjust the tilt angle of the electric seat.

[0044] The Hall sensor 120, which is a magneto-electric converter using the Hall effect, can sense the position of the electric seat. In other words, the Hall sensor 120 can sense the current position (e.g., whether the electric seat has moved forward) by sensing the change in the magnetic field caused by the movement of the electric seat and by transmitting the output signal to the controller 150.

[0045] The drive motor 130 is driven to tilt the backrest of the electric seat in a forward or reverse orientation, or it can be driven to slide the seat in a forward or reverse orientation.

[0046] The current sensor 140 senses the level of the output current from the drive motor 130.

[0047] The controller 150 can be electrically connected to the switch 110, the Hall sensor 120, the drive motor 130, and the current sensor 140, and can electrically control each component. It can also be a circuit that executes software commands. Therefore, the controller 150 can perform various data processing and calculations, as described below.

[0048] Controller 150 can process signals transmitted between components. Controller 150 can be, for example, an electronic control unit (ECU), a microcontroller unit (MCU), or another low-level controller installed in the vehicle.

[0049] The controller 150 can be trained using Hall sensor 120 and current sensor 140 to determine a reference current level for anti-pinch protection relative to each position of the power seat (here, the term "reference current level" is used interchangeably with the terms "reference current value," "reference current level value," and "reference level"). The controller 150 can determine anti-pinch protection by comparing the level of the current value measured relative to each position of the power seat with the trained reference current level used to determine anti-pinch protection.

[0050] The controller 150 can flexibly calculate the reference current level for determining the anti-pinch function relative to each position of the electric seat using a learning algorithm. In this case, the learning algorithm can employ typical algorithms to generate the output through learning based on the input data.

[0051] The controller 150 can measure the current level output from the drive motor 130 relative to each operating direction (motor operating direction) of the drive motor 130 and each position of the electric seat (here, the terms "current level" and "current value" can be used interchangeably). The controller 150 can input the measured current level into a learning algorithm to output a trained current value. In this case, the operating direction of the drive motor 130 can be as follows: Figure 4The position can be either forward 'A' or reverse 'B', and the position of the electric seat can be the tilt angle (tilt position) 'C' of the electric seat. In this case, the Hall sensor 120 can sense the operating direction of the drive motor and the position of the electric seat, and can provide the sensing results to the controller 150. Figure 4 This is a view showing the direction of movement of an electric seat according to an embodiment of the present disclosure.

[0052] The controller 150 can calculate a reference current level for determining the anti-pinch function relative to each position of the power switch by adding the difference between the average value of the measured drive motor current and the average value of the limiting current to a trained current value. The controller 150 can store the reference current value in the storage device 160.

[0053] That is, the control unit 150 can calculate the reference current level for determining the anti-pinch by subtracting the average value of the limiting current from the average value of the operating current, as shown in Equation 1 below.

[0054] Equation 1

[0055] The reference current level used to determine the anti-pinch function = trained current value + (average operating current - average limiting current)

[0056] When an operation signal is received from the drive motor 130, the controller 150 can determine whether a trained reference current level for determining anti-pinch protection relative to each position of the power seat is stored in the storage device 160. If the reference current level has not been trained, the controller 150 trains the reference current level. If the reference current level has been trained, the controller 150 can use the trained reference current level for determining anti-pinch protection relative to each position of the power seat to determine anti-pinch protection.

[0057] The controller 150 can compare a trained current value with a current value obtained by measuring the level of the output current from the drive motor. When the trained current value is greater than the current value obtained by measuring the level of the output current from the drive motor, the controller 150 can determine that the current state is normal. In the normal state, anti-pinch occurs and the controller can operate the drive motor normally. Figure 6 This is a view showing the current level at each seat position according to an embodiment of the present disclosure. Figure 6 As shown, the trained current value (level) 'D' can be compared with the current value 'E' obtained by measuring the level of the output current from the drive motor.

[0058] The controller 150 sets the relative end positions of the operating portion of the drive motor, and specifically, sets the relative end positions of the operating portion of the drive motor such that the operating portion is narrower than the portion of the drive motor that actually moves. When the drive motor stops, the controller 150 can determine whether the drive motor has reached one of the relative end positions. In this case, as... Figure 4 As shown, the relative end positions of the operating parts include the end position when the electric seat moves forward 'A' and the end position when the electric seat moves backward upward.

[0059] When a limiting current is generated, the controller 150 can determine whether the drive motor has reached one of the positions at opposite ends. For example... Figure 6 As shown, when the drive motor 130 reaches the opposite end position, a limiting current 'G' is generated. Therefore, it can be recognized that the drive motor 130 has reached the opposite end position.

[0060] When the drive motor 130 reaches one of the relative end positions, the controller 150 can correct the training portion relative to each position of the electric seat. In other words, the controller 150 can correct the training position to prevent the drive motor 130 from reaching the relative end position, and can correct the position that is the relative end position, exactly before the current is limited or before 10% of the entire stroke in which the drive motor 130 is driven.

[0061] When the trained current value (reference current value) is less than the current value obtained by measuring the level of the output current from the drive motor, the controller 150 can compare the trained reference current level F used to determine the anti-pinch function relative to each position of the electric seat with the current value E obtained by measuring the level of the output current from the drive motor.

[0062] When the trained reference level used to determine the anti-pinch function relative to each position of the power seat is less than the current value obtained by measuring the level of the output current from the drive motor, the controller 150 can determine whether the pulse signal of the Hall sensor 120 is normal. In this case, a normal pulse signal of the Hall sensor 120 is as follows: Figure 5 As shown. Figure 5 This is a view showing the output signal of a Hall sensor according to an embodiment of the present disclosure.

[0063] When the pulse signal from the Hall sensor 120 is normal, the controller 150 can calibrate the trained reference level used to determine the anti-pinch function relative to each position of the power seat to a higher level. Simultaneously, when the pulse signal from the Hall sensor is abnormal, the controller 150 can determine that an object is pinched and can execute control operations to stop the movement of the power seat and perform a reverse operation.

[0064] Storage device 160 may store data and / or algorithms, such as learning algorithms required for the operation of controller 150. In this case, the learning algorithm may be a typical learning algorithm.

[0065] For example, storage device 160 can store the value of the output current from the drive motor trained by a learning algorithm and the reference current value used to determine the anti-pinch function.

[0066] In addition, the storage device 160 may include at least one storage medium selected from flash memory, hard disk, micro and card type (e.g., security digital (SD) card or ultimate digital card) memory, random access memory (RAM), static RAM (SRAM), read-only memory (ROM), programmable ROM (PROM), electrically erasable programmable ROM (EEPROM), magnetic RAM (MRAM), disk-type memory and optical disk-type memory.

[0067] In the following text, refer to Figure 3 A detailed description is provided of an apparatus for controlling the detection of anti-pinch mechanisms in an electric seat in a vehicle, according to an embodiment of the present disclosure. Figure 3 This is a flowchart illustrating a method for controlling the anti-pinch detection of an electric seat in a vehicle according to an embodiment of the present disclosure.

[0068] In the following text, it is assumed that... Figure 2 The device 100 shown is used to control the anti-pinch detection of power seats in vehicles. Figure 3 The process. Additionally, refer to the following: Figure 3 As can be understood from the description, the operation described as being performed by device 100 is controlled by controller 150 of device 100 for controlling the detection of anti-pinch function of electric seats in vehicles.

[0069] Reference Figure 3 When the operating signal of the drive motor (motor operating signal) is received (S101), the device 100 for detecting the anti-pinch function of the electric seat in the vehicle determines whether the reference current level for determining the anti-pinch function has been trained (S102).

[0070] When the reference current level used to determine the anti-pinch function is not fully trained, the device 100 for controlling the anti-pinch detection uses the motor operation signal to determine the operating direction of the drive motor (motor operation direction) (S103), and identifies the position moved by the electric seat via the Hall sensor 120 (S104). In other words, the device 100 for controlling the anti-pinch detection can determine whether the motor operation direction is forward 'A' or reverse 'B'. Furthermore, the device 100 for controlling the anti-pinch detection of the electric seat can determine the tilt position 'C'.

[0071] The device 100 for controlling anti-pinch detection measures the current level relative to each motor operating direction and each seat position, and trains the measured current level based on a learning algorithm. In this case, the learning algorithm may include a typical learning algorithm to output an output value through learning based on input values. The device 100 then stores the results from the learning process. In other words, data measured relative to each motor operating direction and each seat position is input into the learning algorithm to obtain trained current level values.

[0072] Subsequently, the detection device 100 used to control the anti-pinch function calculates a reference current level value 'F' for determining the anti-pinch function based on the motor operating direction and seat position, such as... Figure 6 As shown. In other words, the reference current level value 'F' is the sum of a trained current level (value) 'D' for each position of the power seat and a constant current value. In this case, the constant current value is the difference between the average value of the drive motor's operating current (motor operating current) and the average value of the limiting current relative to each position of the power seat. As described above, the reference current level used to determine the anti-pinch function is trained relative to each operating direction of the drive motor driving the power seat and each tilt position of the power seat to constantly maintain the difference between the reference current level 'F' used to determine the anti-pinch function and the measured current level 'E' of the drive motor, such as... Figure 6 As shown. Therefore, this prevents reverse operation caused by excessive clamping force or misoperation during normal operation.

[0073] Meanwhile, when training is completed in S102, the device 100 for detecting the anti-pinch function of the electric seat determines the motor operation direction (S106) and identifies the position of the electric seat through Hall sensor input (S107).

[0074] The device 100 for detecting the anti-pinch function of the electric seat in the vehicle measures the operating current of the drive motor (motor operating current) (S108) and compares the trained current data (trained current value) for each motor operating direction and each sensor position with the currently measured current value (S109).

[0075] The device 100 for detecting anti-pinch mechanisms in the power seat determines whether the trained current data (trained reference current value) is greater than the currently measured current value (S110).

[0076] When the trained current data is greater than the currently measured current value, the device 100 for controlling the anti-pinch detection of the electric seat determines that the drive motor is in a normal state of not being pinched and turns on the output of the drive motor (S111).

[0077] The device 100 for detecting the anti-pinch function of the electric seat determines whether to stop the operation of the drive motor (S112), and repeats S107 to S112 when the operation of the drive motor does not stop.

[0078] When the drive motor stops operating, the device 100 for controlling the anti-pinch detection of the electric seat determines whether the motor (drive motor) has reached the end of the motor mechanism (S113). When the motor reaches the end of the motor mechanism, the device 100 for controlling the anti-pinch detection of the electric seat recalibrates the training position based on the end (S114). Typically, a specific end position is arbitrarily set such that the motor stops before a specific part of the motor mechanism, thereby preventing the motor from physically reaching the end of the motor mechanism. Since the seat tilts in the fore-and-aft direction, the motor end position is set when the electric seat moves back and forth. When the drive motor 130 reaches the end position, an error may occur, and a limiting current may be generated (see...). Figure 6 (in the 'G').

[0079] Therefore, when the drive motor 130 reaches the end position, the error can be ignored and the current position can be updated as the endpoint of the training section, and the relative endpoint can be updated in the same way. Furthermore, the point corresponding to 10% of the entire stroke distance moved by the drive motor 130 can be set as the endpoint of the training section.

[0080] Meanwhile, when the trained current data is equal to or less than the data measured in S110, the device 100 for controlling the anti-pinch detection determines whether the trained reference current for determining the anti-pinch is less than the measured data (S115).

[0081] When the trained reference current used to determine anti-pinch is less than the measured data, the detection device 100 for controlling anti-pinch determines whether the Hall sensor pulse is properly input (S116). If the Hall sensor pulse is abnormal, it is sensed as causing clamping, and a reverse operation is performed after stopping the drive motor 130 (S117). In this case, the pulse signal of the Hall sensor has a constant value, such as... Figure 5 As shown.

[0082] When the trained current data is less than or equal to the measured data and the trained reference current used to determine the anti-pinch is less than the measured data, when the pulse signal of the Hall sensor is normal, the device 100 for controlling the detection of the anti-pinch determines that the current level has changed due to the external environment (higher voltage or lower temperature) and corrects the trained current data to a higher value (S118).

[0083] As described above, according to this disclosure, a reference current level for determining the anti-pinch function of the power seat is flexibly set using a learning algorithm relative to the orientation and position of the power seat. Therefore, the difference between the reference current level used to determine the anti-pinch function of the power seat and the measured current remains constant, thereby preventing excessive clamping force or error during normal operation.

[0084] Figure 7 A computing system according to an embodiment of the present disclosure is shown.
