[0002] During vehicle movement, the seat position needs to be constantly monitored. If there is a significant deviation in position during monitoring, it can affect the functioning of some seat functions, interfere with the normal operation of some vehicle components, reduce vehicle safety, and decrease the user's driving and riding experience. Summary of the Invention

[0004] The first aspect of this application provides a seat position calibration method applied to a vehicle. The vehicle includes a seat, a position monitoring device, and a micro switch unit. The position monitoring device is used to monitor the position of the seat. When the seat moves to a preset position, the micro switch unit is triggered. The method includes: acquiring the state of the micro switch unit; wherein the state includes an untriggered state and a triggered state; when the micro switch unit is in the triggered state, controlling the position monitoring device to perform a zero-position calibration operation.

[0005] In the seat position calibration method of this application, the state of the micro-switch unit is acquired to determine whether to control the position monitoring device to perform a zero-position calibration operation. Thus, based on the state of the micro-switch unit, this application can quickly and proactively calibrate the position monitoring device, improving the accuracy and reliability of seat position acquisition. This reduces the probability of deviations in monitoring results due to long-term use of the position monitoring device without position calibration, thereby ensuring the normal operation of the seat function and reducing interference to vehicle components during operation. In various user modes and driving scenarios, this significantly improves the vehicle's interactive experience and safety. Simultaneously, this application reduces maintenance difficulty and monitoring costs, and eliminates the need for users to perform fine-tuning operations or adjustments, reducing operational requirements and improving the user's driving experience.

[0006] In one possible design, obtaining the state of the microswitch unit includes: obtaining the electrical parameters of the circuit in which the microswitch unit is located to determine the state of the microswitch unit.

[0007] In one possible design, the microswitch unit includes a microswitch, a first resistor, and a second resistor. The first resistor and the second resistor have different resistance values. The microswitch is connected in series with either the first resistor or the second resistor. Electrical parameters of the circuit containing the microswitch unit are obtained to determine the state of the microswitch unit. This includes: if the electrical parameters meet a first parameter range, then the microswitch is determined to be electrically connected to the first resistor, and the microswitch unit is in a non-triggered state; if the electrical parameters meet a second parameter range, then the microswitch is determined to be electrically connected to the second resistor, and the microswitch unit is in a triggered state; if the electrical parameters do not meet either the first or second parameter range, then the microswitch unit is determined to be faulty. The first parameter range characterizes the setting range of the electrical parameters when the first resistor is connected to the microswitch; the second parameter range characterizes the setting range of the electrical parameters when the second resistor is connected to the microswitch.

[0008] In one possible design, before the control position monitoring device performs the zero-position calibration operation, the method further includes: timing the time during which the micro switch unit remains in the triggered state to obtain the state duration; when the state duration is greater than or equal to a preset time, controlling the position monitoring device to perform the zero-position calibration operation; when the state duration is less than the preset time, re-timing the time during which the micro switch unit remains in the triggered state.

[0009] In one possible design, the electrical parameters of the circuit containing the micro switch unit are obtained to determine the operating state of the micro switch unit, including: if the electrical parameter is at a first level, the micro switch unit is determined to be in an untriggered state; if the electrical parameter is at a second level, the micro switch unit is determined to be in a triggered state.

[0010] In one possible design, before the control position monitoring device performs a zero-position calibration operation, the method further includes: acquiring at least one motion parameter of the seat within a set time period; wherein the motion parameter includes the force applied by the seat to the micro-switch unit and / or the distance the seat moves within the set time period; when each motion parameter reaches the corresponding preset parameter range, the control position monitoring device performs a zero-position calibration operation.

[0011] In one possible design, controlling the position monitoring device to perform a zero-position calibration operation includes: controlling the position monitoring device to enter a setting state; wherein, in the setting state, the position parameters of the position monitoring device are adjusted to a preset value corresponding to a preset position.

[0012] A second aspect of this application provides an electronic device, including a processor and a memory, wherein the memory is used to store a computer program; and the processor is used to execute the program stored in the memory to implement the seat position calibration method as described in any of the above embodiments.

[0021] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0022] The precise position information of the seats directly affects many extended functions of the vehicle. For example, the seat's fore-aft and height coordinates are related to the line-of-sight calibration of the adaptive cruise control (ACC), the projection adaptation of the head-up display (HUD), the illumination area of ​​the interior ambient lighting, and the pretensioning logic of the collision safety restraint system. Related technologies use sliding rheostats for position recognition, which offer high accuracy but are also costly. Furthermore, sliding rheostats are limited by mechanical inertia, resulting in a slow response time. If seat position is detected solely by Hall effect sensors, long-term use can lead to accumulated deviations. When these deviations are significant, manual calibration by the user is required, impacting the user experience.

[0023] This application provides a seat position calibration method, electronic device, vehicle, and computer-readable storage medium, which can solve the problems of large deviations occurring during long-term seat position monitoring, difficulty in automatic calibration, and high cost.

[0024] Please see Figure 1 , Figure 1 This is a block diagram of the modular composition of a vehicle provided in one embodiment of this application. For example... Figure 1 As shown, the vehicle 100 includes at least one seat 110 and a seat adjustment system 120. The seat 110 is adjustable, and the seat adjustment system 120 includes a seat controller 121. The seat controller 121 controls the position adjustment process of each seat 110 in the vehicle 100, including but not limited to: fore-and-aft position adjustment of the seat 110 in the vehicle 100, vertical position adjustment of the seat 110 in the vehicle 100, and angle adjustment between the seat cushion and backrest of the seat 110.

[0025] In one embodiment of this application, the seat adjustment system 120 further includes at least one motor 122. The seat controller 121 drives the motor 122 to operate, and the motor 122 is used to adjust the fore-and-aft position of the seat 110 in the vehicle 100. The seat 110 includes a slide rail 111, and the motor 122 is drivenly connected to the slide rail 111. When the motor 122 rotates, it causes the slide rail 111 to change position, thereby changing the fore-and-aft position of the seat 110 in the vehicle 100.

[0026] Exemplarily, the vehicle 100 also includes a position monitoring device 130 for monitoring the position of the seat 110. The position monitoring device 130 may include a Hall sensor. A Hall sensor is a magnetic field sensor based on the Hall effect. When the motor 122 rotates, the Hall sensor continuously detects changes in the magnetic field. After the signal is converted by an analog-to-digital converter (ADC), the position of the seat 110 is determined by accumulating and counting the transitions in the converted signal. The position monitoring device 130 may also be a potentiometer, a magnetostrictive sensor, or other devices capable of acquiring the position of the seat 110. This application does not limit the specific design of the position monitoring device 130.

[0027] In one embodiment of this application, the vehicle 100 further includes an electronic device 140. The position monitoring device 130 and the seat controller 121 can be communicatively connected to the electronic device 140. The electronic device 140 obtains the position of the seat 110 through the position monitoring device 130. The electronic device 140 can send information to the seat controller 121, enabling the seat controller 121 to control the seat 110 based on the received information. The communication connection can include wired connections such as Controller Area Network (CAN), Local Interconnect Network (LIN), or fiber optic cables, or wireless connections such as Wireless Fidelity (Wi-Fi) or Bluetooth. This application does not limit the specific method of communication connection. Optionally, the electronic device 140 can be integrated with the seat controller 121, the body controller, or other controllers on the vehicle 100. The body controller (BCM) is responsible for the centralized management and control of the operation of various electrical modules within the vehicle body, coordinating the actions of each electrical module, such as motors, relays, and LED lights, to achieve intelligent and integrated vehicle body function control. The electronic device 140 can also be an independently configured device or module. This application does not limit the specific configuration method of the electronic device 140.

[0028] In one embodiment of this application, the vehicle 100 further includes a microswitch unit 150, which is triggered when the seat 110 moves to a preset position. The microswitch unit 150 can be disposed on the moving path of the seat 110, and the preset position can be set as the range between the seat 110 contacting one end of the microswitch unit 150 and the seat 110 disengaging from the other end of the microswitch unit 150. For example, as... Figure 2As shown, the micro switch unit 150 can be disposed under the seat 110. The forwardmost position of the seat 110 is designated as the front stop point P, and the rearmost position is designated as the rear stop point Q. Several micro switch units 150 can be disposed between the front stop point P and the rear stop point Q. During the forward and backward movement of the seat 110, the lower part of the seat cushion can trigger the micro switch units 150. When any micro switch unit 150 is triggered, the position monitoring device 130 performs a zero-position calibration operation. This application does not limit the specific number and location of the micro switch units 150; those skilled in the art can configure them according to actual needs. In other embodiments, the micro switch units 150 can also be disposed on the left or right side of the seat 110. This application does not limit the specific placement of the micro switch units 150. This ensures that the seat 110 can be accurately calibrated, reducing the probability of deviations in monitoring results due to long-term use of the position monitoring device without position calibration, thereby ensuring the normal operation of the seat function and improving the accuracy and reliability of obtaining the seat position.

[0029] Those skilled in the art will understand that the schematic diagram is merely an example of vehicle 100 and does not constitute a limitation on vehicle 100. Vehicle 100 may include more or fewer components than shown in the diagram, or combine certain components, or different components. For example, vehicle 100 may also include a power system and an electrical system.

[0030] Please see Figure 3 , Figure 3 A flowchart illustrating the steps of a seat position calibration method according to an embodiment of this application is shown. Figure 3 As shown, this application provides a seat position calibration method applied to a vehicle 100, and controlled by an electronic device 140 (such as...). Figure 1 (As shown) the procedure is performed to calibrate the position monitoring device 130. The seat position calibration method provided in this application may include the following steps: Step S10: Obtain the status of the micro switch unit.

[0031] The states include an untriggered state and a triggered state. Understandably, the state of the microswitch unit 150 is determined by acquiring the electrical parameters of the circuit containing the microswitch unit 150. These electrical parameters effectively determine whether the microswitch unit 150 has been effectively triggered, reducing the probability of misjudging its state, improving the accuracy of the calibration position monitoring device 130, ensuring the accuracy of monitoring the position of the seat 110, and guaranteeing the normal operation of the vehicle 100.

[0032] In one embodiment of this application, such as Figure 4As shown, the microswitch unit 150 includes a microswitch 151, a first resistor R1, and a second resistor R2. The first resistor R1 and the second resistor R2 have different resistance values. The microswitch 151 is connected in series with either the first resistor R1 or the second resistor R2. If the electrical parameters meet the first parameter range, it is determined that the microswitch 151 is electrically connected to the first resistor R1, and the microswitch 151 unit is in an untriggered state. If the electrical parameters meet the second parameter range, it is determined that the microswitch 151 is electrically connected to the second resistor R2, and the microswitch 151 unit is in a triggered state. The first parameter range characterizes the setting range of the electrical parameters when the first resistor R1 is connected to the microswitch 151; the second parameter range characterizes the setting range of the electrical parameters when the second resistor R2 is connected to the microswitch 151. Understandably, by using the first resistor R1 and the second resistor R2 with different resistance values, it is possible to effectively determine whether the microswitch 151 is triggered. The microswitch 151 can be a single-pole double-throw (SPDT) switch. The microswitch 151 can include a common terminal A, a first connection terminal B, and a second connection terminal C. One end of the common terminal A is grounded, and the other end is connected to either the first connection terminal B or the second connection terminal C. The first connection terminal B is connected to a first resistor R1, and the second connection terminal C is connected to a second resistor R2. When the electrical parameters meet the second parameter range, the electronic device 140 controls the microswitch 151, which normally connects the common terminal A to the first connection terminal B (i.e., the common terminal A, the first connection terminal B, and the first resistor R1 are conducting), to connect the common terminal A to the second connection terminal C, thereby enabling the common terminal A, the second connection terminal C, and the second resistor R2 to conduct. If the electrical parameters do not meet the first and second parameter ranges, a fault is determined in the microswitch 151 unit. For example, the fault may include an open circuit or a short circuit, such as a loose wiring harness. This application does not limit the specific fault conditions or their causes. At this time, the electronic device 140 can issue an alarm reminder to the user, such as sending a pop-up message to the instrument panel of the vehicle 100 or the user's mobile phone. This application does not limit the specific method of reminder.

[0033] For example, if the electrical parameter is at a first level, the micro switch unit 150 is determined to be in an untriggered state; if the electrical parameter is at a second level, the micro switch unit 150 is determined to be in a triggered state. Understandably, with a preset position set to zero, the electronic device 140 continuously acquires electrical parameters, and the level changes when the seat 110 moves to the zero position. For example, the first level can be high, and the second level can be low. Alternatively, the first level can be low, and the second level can be high. In other embodiments, the first and second levels can also be other preset levels; this application does not limit the specific setting of the first and second levels.

[0034] Step S20: When the micro switch unit is in the triggered state, the control position monitoring device performs a zero-position calibration operation.

[0035] Specifically, the electronic device 140 controls the position monitoring device 130 to enter a setting state; wherein, in the setting state, the position parameters of the position monitoring device 130 are adjusted to a preset value corresponding to a preset position. For example, the position monitoring device 130 sets the preset value to 0 or a set reference value, etc. This application does not limit the specific setting method of the setting state.

[0036] In one embodiment of this application, after performing a zero-position calibration operation, the position monitoring device 130 can also perform a self-test on its monitoring results. If the position monitoring device 130 includes a Hall sensor, the self-test can include comparing the Hall sensor reading with a expected value. When the reading matches the expected value, the position calibration of the seat 110 is determined to be complete. The self-test can also include other operating methods; this application does not limit the specific settings of the self-test. This effectively ensures the accuracy of the position calibration, guarantees the normal operation of the seat function, eliminates the need for fine-tuning by the user, reduces operational requirements for the user, lowers maintenance difficulty and monitoring costs, and improves the user's driving experience.

[0037] In some embodiments, such as Figure 5 As shown, step S10 may include the following steps: Step S11: Time the duration of the micro switch unit in the triggered state to obtain the state duration.

[0038] In one embodiment of this application, when the duration of the state is greater than or equal to a preset time (e.g., the preset time is set to 60ms), the position monitoring device 130 is controlled to perform a zero-position calibration operation; when the duration of the state is less than the preset time, the time during which the micro switch unit 150 remains in the triggered state is re-timed. Understandably, the micro switch unit 150 may experience triggering anomalies, such as jitter or false triggering. Jitter refers to the situation where, at the instant the micro switch 151 switches from one state to another, due to factors such as the elasticity of the mechanical structure, unevenness of the contact surface, or electromagnetic interference at the moment of contact, the switch contacts do not immediately and stably connect or disconnect, but instead experience multiple rapid and irregular connections and disconnections within a very short time. By monitoring the duration of the state, the delay detection of the micro switch unit 150 can be achieved, thereby determining that the micro switch unit 150 has been effectively triggered, reducing the impact of abnormal triggering of the micro switch unit 150 on the calibration results, and improving the accuracy of the position calibration of the seat 110. This application does not impose excessive limitations on the specific setting of the preset time; those skilled in the art can set it based on actual needs.

[0039] Step S12: Obtain at least one motion parameter of the seat within a set time period.

[0040] The motion parameters include the force applied by the seat 110 to the micro-switch unit 150 and / or the distance the seat 110 moves within a set time. When each motion parameter reaches its corresponding preset parameter range, the control position monitoring device performs a zero-position calibration operation. Understandably, as... Figure 4 As shown, the seat 110 applies force to the microswitch unit 150 to adjust the connection of the microswitch 151 from common terminal A to first connection terminal B to common terminal A to second connection terminal C. This application does not limit the specific setting method of the preset parameter range corresponding to the applied force; those skilled in the art can set it based on the actual mechanical structure of the microswitch 151. By measuring the movement distance of the seat 110 within a set time, it is possible to determine whether the seat 110 has adjusted the seat position for the user, reducing the probability of misjudging seat 110 movement due to mechanical loosening or external abnormal interference. This improves the accuracy of the monitoring results and ensures the normal operation of the vehicle 100 functions.

[0041] It should be understood that, depending on different needs, such as Figure 5 The order of steps in the flowchart shown can be changed, and some steps can be omitted.

[0043] Understandably, computer programs can be in the form of source code, object code, executable files, or some intermediate form. Computer programs can be stored in a computer-readable storage medium. Computer-readable storage media can include: any entity or device capable of carrying computer program code, recording media, USB flash drives, portable hard drives, magnetic disks, optical disks, computer memory, read-only memory (ROM), random access memory (RAM), electrical carrier signals, telecommunication signals, and software distribution media, etc.
