Description

[Technical Field]

[0001] This application relates to the field of vehicle control technology, and in particular to a seat position detection system, method and apparatus. [Background Technology]

[0002] Seat memory is a crucial feature in automotive systems for enhancing user comfort. It primarily works by storing historical seat position information, allowing customers to easily retrieve this data and adjust the seat to their desired position. Current seat memory solutions utilize Hall effect motors or add Hall sensors to the tail of ordinary motors. By collecting Hall signals, the distance traveled by the motor is determined and recorded, thus storing the position information. However, this method relies heavily on Hall signals to record the relative position of the seat, lacking an absolute position as a reference point. This means the system cannot automatically correct for errors, potentially leading to inconsistencies. [Summary of the Invention]

[0003] This application provides a seat position detection system, method, and apparatus. During the movement of the seat driven by the slide rail assembly, the controller reads multiple pre-set data bits to directly obtain the absolute position information of the seat.

[0004] In a first aspect, embodiments of this application provide a seat position detection system, which includes a controller and a slide rail assembly. The slide rail assembly includes a fixed part and a sliding part. The controller is connected to the fixed part. The fixed part is provided with multiple sets of data bits. Different data bits correspond to different position information of the seat. During the process of the seat moving and causing the sliding part to slide along the fixed part, the contact bits slide past the multiple sets of data bits in sequence. When any data bit comes into contact with the contact bit, the controller reads the encoded information of the data bit and parses the encoded information to obtain the current position information of the seat.

[0005] The seat position detection system proposed in this application has multiple data bits set on the fixed part of the slide rail assembly, and contact bits set on the sliding part of the slide rail assembly. Each data bit records the absolute position information of the seat. Thus, as the slide rail assembly moves the seat, the contact bits of the sliding part sequentially contact different data bits. When a contact bit contacts a data bit, the circuit continuity controller reads the corresponding position information of the data bit to obtain the absolute position of the seat. This seat position detection system, through a simple structural design, completes the absolute position detection of seat movement without the need for position information correction, avoiding system errors caused by position information correction.

[0006] In one possible implementation, the data bit includes a first encoding bar and a second encoding bar, which are symmetrically arranged; the controller reads encoded information based on the first encoding bar when the sliding part slides across the data bit in a first direction, which is the same as reading the same encoded information based on the second encoding bar when the sliding part slides across the data bit in a second direction.

[0007] In one possible implementation, the fixing part generates a first trigger signal when any data bit comes into contact with the contact bit; the first trigger signal is used to trigger the controller to start the next encoding read.

[0008] In one possible implementation, an identification bit is provided between adjacent data bits; the fixing part generates a second trigger signal when any identification bit comes into contact with the contact bit; the second trigger signal is used to trigger the controller to stop the previous encoding read.

[0009] In one possible implementation, the identification bit and the data bit are patches of different lengths; the duration of the low-level signal generated when the identification bit contacts the contact bit is different from the duration of the low-level signal generated when the data bit contacts the contact bit.

[0010] In a second aspect, embodiments of this application provide a seat position detection method, applied to a controller in a seat position detection system provided in the first aspect of this application. The seat position detection system further includes a slide rail assembly, the slide rail assembly having a fixed part and a sliding part, the sliding part including a contact position, and the fixed part including multiple sets of data bits. The method includes:

[0011] Upon receiving the first trigger signal generated by the contact bit and the data bit contacting each time, the pre-set encoded information of the data bit is read.

[0012] The encoded information is parsed, and the seat position corresponding to the encoded information is obtained by matching different data bits with the seat position in a pre-set correspondence.

[0013] Calculate the position information read each time, output and record the total distance the seat has moved and the current position of the seat.

[0014] In one possible implementation, an identification bit is set between adjacent data bits; after starting to read the pre-set encoded information of the data bits, the method further includes: stopping the reading of encoded information when a second trigger signal generated by the contact bit and the identification bit coming into contact is collected.

[0015] In one possible implementation, an identification bit is provided between adjacent data bits; the identification bit and the data bits are patches of different lengths, and a low-level signal is generated when the contact bit contacts the identification bit and the data bit; the method further includes:

[0016] Determine the time range corresponding to the duration of the received low-level signal; the time range includes a first time length during which the contact bit slides over the data bit, and a second time length during which the contact bit slides over the identification bit;

[0017] Upon receiving a first trigger signal generated by the contact point and the data point coming into contact, the system begins reading the pre-set encoded information of the data point, including:

[0018] For each instance of a low-level signal duration corresponding to the first time length, the pre-set encoded information of the data bits is read.

[0019] In one possible implementation, the pre-set correspondence between different data bits and seat positions includes: the percentage of the seat's movement range from the starting point to the current position corresponding to each data bit; calculating the position information read each time, outputting and recording the total distance the seat has moved and the seat's current position, including:

[0020] Obtain the percentage of the seat's movement range at the stopping position when the seat last stopped;

[0021] Calculate the difference between the percentage of the current position relative to the range of seat movement and the percentage of the range of seat movement corresponding to the stopping position when the seat last stopped moving.

[0022] The total distance the seat moves is obtained by multiplying the difference by the range of seat movement, and the current position of the seat is obtained by multiplying the current position as a percentage of the range of seat movement by the range of seat movement.

[0023] Thirdly, embodiments of this application provide a seat position detection device, which is disposed in a controller of the seat position detection system provided in the first aspect of this application. The seat position detection system further includes a slide rail assembly, the slide rail assembly having a fixed part and a sliding part, the sliding part including a contact position, and the fixed part including multiple sets of data bits. The method includes:

[0024] The device includes:

[0025] The information reading module is used to start reading the pre-set encoded information of the data bit whenever a first trigger signal is generated when the contact bit and the data bit come into contact.

[0026] The parsing module is used to parse the encoded information and obtain the seat position corresponding to the encoded information by using a pre-set correspondence between different data bits and seat positions.

[0027] The calculation module is used to calculate the position information read each time, output and record the total distance the seat has moved and the current position of the seat.

Detailed Implementation Methods

[0042] To better understand the technical solutions in this specification, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0043] It should be understood that the described embodiments are merely some, not all, of the embodiments in this specification. All other embodiments obtained by those skilled in the art based on the embodiments in this specification without inventive effort are within the scope of protection of this specification.

[0044] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this specification. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0045] In current technology, seat position calculations in the field of seat memory rely on pulse signals emitted by Hall effect sensors. When these Hall signals are interfered with, the internal position information of the controller deviates, resulting in system errors. Since this method of detecting seat position based on Hall signals records the relative distance of seat movement—for example, pre-calibrating the distance the seat moves when the Hall motor rotates one revolution—and accumulating the distance traveled by emitting Hall signals with each rotation, the accumulated error from each seat movement over time necessitates resetting the memory system. Because the system uses relative coordinates, the anti-pinch function may be falsely triggered due to system errors. While calibration methods can eliminate these errors, they require additional steps and labor costs, and the calibration cycle is uncertain, impacting customer experience. Furthermore, because current technology records the relative distance of seat movement, the position calculation during seat adjustments requires consideration of the direction of movement, making the calculation complex.

[0046] In view of the above problems, this application proposes a seat position detection system, which consists of an absolute position coordinate axis positioning design composed of a scale on a slide rail and a contact switch. When the seat moves, the contact switch will move along the coordinate scale. The controller can obtain the current position signal based on the contact signal between the switch and the coordinate scale mark. The design is simple in construction and highly reliable.

[0047] Figure 1 This is a schematic diagram of the seat position detection system proposed in an embodiment of this application, as shown below. Figure 1 The seat position detection system shown may include a controller 1 and a slide rail assembly 2.

[0048] Figure 2 This is a schematic diagram of the slide rail assembly provided in this application in a specific example. Figure 3 yes Figure 2 Exploded view, such as Figure 2 and Figure 3 As shown:

[0049] The slide rail assembly 2 includes a fixed part 21 and a sliding part 22, with the controller 1 connected to the fixed part 21. The sliding part 22 has a contact position 221 on its body; the fixed part 21 has multiple sets of data positions 211 on its body. Different data positions 211 correspond to different position information of the seat. These multiple sets of data positions 211, each recording different position information, are arranged sequentially on the fixed part 21, giving it the function of a scale for recording absolute position.

[0050] Data bit 211 can be a metal patch carrying two-dimensional information, and contact bit 221 can be a steel ball. When contact bit 221 contacts data bit 211, the circuit between controller 1 and fixing part 21 is connected, and controller 1 can read relevant signals and then analyze the relevant signals to obtain the position of the seat.

[0051] During the process of the sliding part 22 sliding along the fixed part 21 to move the seat, the contact position 221 slides past the multiple sets of data positions 211 in sequence. When any data position 211 comes into contact with the contact position 221, the controller 1 reads the encoded information of the data position 211 and parses the encoded information to obtain the current position information of the seat.

[0052] Continue to refer to Figure 2 and Figure 3 , Figure 3A coordinate system is defined, with x representing the direction and y representing the vertical direction. The slide rail assembly 2 can connect to the seat. A response motor drives the sliding part 22 of the slide rail assembly 2 to slide. The sliding part 22 moves the seat, and this movement is related to the sliding part 22. Therefore, the absolute position of the seat is related to the distance the sliding part 22 moves. Based on this relationship, data bits 211 are pre-calibrated to correspond to different seat position information. By reading the encoded information carried by data bits 211, the absolute position of the seat can be obtained.

[0053] The aforementioned seat position detection system is based on the principle that the slide rail assembly 2 drives the seat to move. By setting data bits 211 in the fixed part 21, a mapping relationship is established between the encoded information carried by the data bits 211 and the absolute position of the seat, giving the fixed part 21 the function of a scale for recording the absolute position. Correspondingly, contact bits 221 are set in the sliding part 22. During the sliding process of the sliding part 22, the contact bits 221 will contact and conduct with multiple data bits 211, thereby generating a signal. The controller 1 collects the signal to read the absolute position of the seat. The above structure is simple, and the controller 1 can directly read the absolute position of the seat, avoiding system errors caused by the accumulation of relative positions, and eliminating the need for system correction. At the same time, the fixed part 21 sets an identification bit 212 between adjacent data bits 211. The duration of the signal generated by the contact bit 221 contacting the identification bit 212 is different from the duration of the signal generated by the contact bit 221 contacting the data bit 211, thereby distinguishing two adjacent data bits 211.

[0054] Figure 4 This is a schematic diagram of the data bits provided in the embodiments of this application in a specific embodiment, such as... Figure 4 As shown, data bits 211 have a first coding bar 2111 and a second coding bar 2112, and the first coding bar 2111 and the second coding bar 2112 are symmetrically arranged;

[0055] The controller 1 reads encoded information based on the first encoding bar 211 when the sliding part 22 slides over the data bit 211 in the first direction, which is the same as when the sliding part 22 slides over the data bit 211 in the second direction and reads the same encoded information based on the second encoding bar 2112.

[0056] In seat memory applications, there are scenarios where the seat needs to be adjusted back and forth based on user requirements, such as moving the seat from point A to point B and then back to point A. To address this scenario, one specific embodiment of this application proposes symmetrically arranged data bits 211. The sliding part 22 reads the first code bar 2111 from point A to point B to obtain code information AA, and the sliding part 22 reads the first code bar 2112 from point A to point B to obtain code information BB. Code information AA and code information BB are identical. This embodiment of the application, by setting symmetrical data bits 211, avoids data reading differences caused by the sliding direction of the sliding part 22, effectively filters external interference, and increases system fault tolerance.

[0057] Figure 5 This is a schematic diagram of the data bits provided in the embodiments of this application in another specific embodiment, such as... Figure 5 As shown, an identification bit 212 is provided between adjacent data bits 211; the fixing part 21 generates a second trigger signal when any identification bit 212 comes into contact with the contact bit 221; the second trigger signal is used to trigger the controller 1 to stop the previous encoding read; the fixing part 21 generates a first trigger signal when any data bit 211 comes into contact with the contact bit 221; the first trigger signal is used to trigger the controller 1 to start the next encoding read.

[0058] The duration of the low-level signal generated when the identification bit 212 contacts the contact bit 221 is different from the duration of the low-level signal generated when the data bit 211 contacts the contact bit 211.

[0059] The identification bit 212 and the data bit 211 can be set as patches of different lengths. The time it takes for the contact bit 221 to slide over the data bit 211 is different from the time it takes for the contact bit 221 to slide over the identification bit 212, so the duration of the generated trigger signal is different. Therefore, the controller can analyze the duration of the first trigger information and the second trigger signal to determine whether the current contact bit 221 is contacting the identification bit 212 or the data bit 211. If the controller 1 determines that the contact bit 221 is contacting the data bit 211, it starts to execute the operation of reading the encoded information. If the controller 1 determines that the contact bit 221 is contacting the identification bit 212, it does not execute the operation of reading the encoded information and stops the previous encoding reading to avoid confusion between the encoded information of the corresponding data bit 211 read in the previous reading and the encoded information of the corresponding data bit 211 read in the next reading.

[0060] Since the seat position detection system proposed in this application triggers or stops data reading through contact between contact bit 221 and data bit 211, or contact bit 221 and identification bit 212, and the controller 1 reads coded information through contact between contact bit 221 and data bit 211, the above process does not require a complex signal source. Therefore, the fixing part 21 can be connected to a grounded signal source. The second trigger signal generated by contact bit 212 contacting contact bit 221, and the first trigger signal generated by contact bit 211 contacting contact bit 221, are both low-level signals. Low-level signal transmission is stable, has strong anti-interference ability, and ensures the stability of the seat position detection system.

[0061] The process by which the controller in the seat position detection system proposed in this application reads the encoded information of data bit 211 and parses the encoded information to obtain the current position information of the seat may include:

[0062] Each time the first trigger signal generated by the contact point and the data point comes into contact, the pre-set encoded information of the data point is read; the encoded information is parsed, and the seat position corresponding to the encoded information is obtained from the pre-set correspondence between different data points and seat positions; the position information read each time is calculated, and the total distance the seat moves and the current position of the seat are output and recorded.

[0063] Controller 1 can also perform the following operations during the process of parsing the encoded signal:

[0064] Determine the time range corresponding to the duration of the received low-level signal; the time range includes a first time length during which the contact bit 221 slides over the data bit 211, and a second time length during which the contact bit 221 slides over the identification bit 212; each time a first trigger signal generated by the contact bit 221 and the data bit 211 contact is acquired, start reading the pre-set encoded information of the data bit 211, including: each time the duration of the low-level signal corresponds to the first time length, start reading the pre-set encoded information of the data bit.

[0065] An identification bit is set between adjacent data bits; after starting to read the pre-set encoded information of the data bits, the method further includes: stopping the reading of encoded information when a second trigger signal generated by the contact bit 221 and the identification bit 212 coming into contact is collected.

[0066] In this embodiment, the controller 1 can determine whether the sliding part 22 has slid to the position where the contact position 221 contacts the data position 211 based on whether the first trigger signal has been collected, thereby determining whether to read the encoded information. Since an identification position 212 is provided between adjacent data positions 211, and the identification position 212 and the data position 211 are patches of different lengths, the duration of the first contact signal generated by the contact position 221 contacting the data position 211 and the duration of the second contact signal generated by the contact position 221 contacting the identification position 212 are different. Therefore, the controller 1 can also determine whether the sliding part 22 has slid to the position where the contact position 221 slides past the data position 211 and reaches the position where the contact position 221 contacts the identification position 212 based on whether the second trigger signal has been collected, thereby stopping the previous reading of encoded information and preparing for the next reading of encoded information.

[0067] In one example of this application, the mapping relationship between different data bits 211 and different seat position information can be the percentage of the seat's movement range as it moves from the starting point to the current position. After reading the encoded information, controller 1 calculates the seat's position based on the percentage of the seat's movement range as it moves from the starting point to the current position and the seat's movement range.

[0068] The process by which controller 1 "calculates the position information read each time, outputs and records the total distance the seat has moved and the current position of the seat" may include:

[0069] Obtain the percentage of the seat's movement range at the stopping position when the seat last stopped;

[0070] Calculate the difference between the percentage of the current position relative to the range of seat movement and the percentage of the range of seat movement corresponding to the stopping position when the seat last stopped moving.

[0071] The total distance the seat moves is obtained by multiplying the difference by the range of seat movement, and the current position of the seat is obtained by multiplying the current position as a percentage of the range of seat movement by the range of seat movement.

[0072] The seat position detection system in this application embodiment sets identification bits 212 and data bits 211 of different lengths to provide information to the controller 1 to distinguish whether the current position is the position for reading encoded information or the position for reading the gap of encoded information, so that the controller 1 can clearly read the timing of the encoded information and avoid confusion of the read encoded information.

[0073] Assume the fixed part 21 has four sets of data bits 211: C, D, E, and F. The movable range of the seat is Y cm, which represents the range of movement of the seat from its original position to its farthest position. The encoded information carried by C corresponds to 20% of Y cm, the encoded information carried by D corresponds to 40% of Y cm, the encoded information carried by E corresponds to 60% of Y cm, and the encoded information carried by W corresponds to 80% of Y cm. If the seat moves from point V to point W, the controller 1 obtains the encoded information read when the seat stopped moving last time, which is 20% of Y cm. The seat is in contact at point V. Bit 221 contacts C; Controller 1 reads the current encoded information as 60% of Ycm. When the seat is at point W, bit 221 contacts E; Controller 1 calculates the difference between the percentage of the current position relative to the seat's movement range and the percentage of the seat's movement range corresponding to the stopping position when the seat stopped last time, which is 40%. Controller 1 obtains the total seat movement distance as Y·40% based on the product of the difference and the seat's movement range. Based on the product of the percentage of the current position relative to the seat's movement range and the seat's movement range, Controller 1 obtains the current seat position as Ycm·60%.

[0074] If the seat moves from point M to point N, controller 1 obtains the encoded information read when the seat stopped moving last time, which is 80% of Ycm. When the seat was at point M, contact bit 221 was in contact with F. Controller 1 reads the encoded information for the current time as 60% of Ycm. When the seat is at point N, contact bit 221 is in contact with E. Controller 1 calculates the difference between the percentage of the current position relative to the seat's movement range and the percentage of the corresponding stopping position relative to the seat's movement range when the seat stopped moving last time, which is 20%. Based on the product of the difference and the seat's movement range, controller 1 obtains the total distance the seat moved as Y·20%. Based on the product of the percentage of the current position relative to the seat's movement range and the seat's movement range, controller 1 obtains the current position of the seat as Ycm·60%.

[0075] The example above, in which controller 1 parses the encoded information to obtain the seat position and the seat movement distance, only needs to read the encoded information to obtain the percentage of the seat's movement range from the starting point to the current position, without needing to refer to the seat's movement direction, thus reducing the computational complexity of controller 1.

[0076] Figure 6 This is a flowchart of the seat position detection method proposed in the embodiments of this application. The seat position detection method is applied to the seat position detection system proposed in other embodiments of this application. The structure and working principle of the seat position detection system have been described in detail in the embodiments of the seat position detection system, and will not be repeated in this embodiment.

[0077] The seat position detection system includes a controller and a slide rail assembly, the slide rail assembly having a fixed part and a sliding part, the sliding part including a contact position, and the fixed part including multiple sets of data positions.

[0078] like Figure 6 As shown, the steps of the controller executing the seat position detection method include:

[0079] Step S61: Each time the first trigger signal generated by the contact bit and the data bit coming into contact is collected, the pre-set encoded information of the data bit is read.

[0080] Step S62: Parse the encoded information and obtain the seat position corresponding to the encoded information by using the pre-set correspondence between different data bits and seat positions.

[0081] Step S63: Calculate the position information read each time, output and record the total distance the seat has moved and the current position of the seat.

[0082] The pre-set correspondence between different data bits and seat positions includes: the percentage of the seat's movement range from the starting point to the current position corresponding to different data bits; step S63 includes sub-steps S631-S634;

[0083] Step S631: Obtain the percentage of the seat's movement range when the seat stopped at the last movement.

[0084] Step S632: Calculate the difference between the percentage of the current position relative to the seat's movement range and the percentage of the seat's movement range corresponding to the stopping position when the seat last stopped moving.

[0085] Step S633: Based on the product of the difference and the seat movement range, obtain the total distance the seat moves; based on the product of the percentage of the current position relative to the seat movement range and the seat movement range, obtain the current position of the seat.

[0086] An identification bit is provided between adjacent data bits; the identification bit and the data bit are patches of different lengths, and a low-level signal is generated when the contact bit comes into contact with the identification bit and the data bit; Figure 7 This is a flowchart of the seat position detection method according to another embodiment of this application, as follows: Figure 7 As shown, the steps of the controller executing the seat position detection method may further include:

[0087] Step S71: Determine the time range corresponding to the duration of the received low-level signal; the time range includes the first time length during which the contact bit slides over the data bit, and the second time length during which the contact bit slides over the identification bit.

[0088] Step S72: For each time the duration of the low-level signal collected corresponds to the first time length, start reading the pre-set encoding information of the data bits.

[0089] Step S73: Stop reading the encoded information when the duration of the low-level signal corresponds to the second time length.

[0090] The duration of each low-level signal collected corresponds to the second time length, indicating that the second trigger signal generated by the contact bit and the identification bit contacting each other is collected. When the second trigger signal generated by the contact bit and the identification bit contacting each other is collected, the sliding part slides to the contact bit contacting the identification bit, that is, the sliding part slides to the contact bit being between two adjacent data bits, and the controller stops reading the encoded information to avoid data confusion.

[0091] Step S74: Parse the encoded information and obtain the seat position corresponding to the encoded information by using the pre-set correspondence between different data bits and seat positions.

[0092] Optional examples of the seat position detection method implemented in this application have been described in the seat position detection system embodiments proposed in this application, and will not be repeated here.
