[0053] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0054] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the embodiments of the present application should have the usual meanings understood by people with ordinary skills in the field to which this application belongs.

[0055] It should be understood herein that any number of elements in the drawings is for illustration only and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0056] Based on the description of the above background technology, the following situations also exist in the related art:

[0057] Vehicle seat rails achieve forward and backward adjustment through guide rail assemblies. However, during adjustment, these rails can squeeze foreign objects, such as passenger clothing or the edges of objects, causing damage to the rails, failure of the seat adjustment function, and even injury to the passenger. If the foreign object is a lighter, squeezing it during seat rail movement could cause a fire, posing a significant hazard. Related technologies rely on manual inspection and mechanical structures, lacking effective foreign object detection methods. This makes it difficult to ensure the timeliness and accuracy of foreign object detection, especially when the seat adjusts automatically or at high speeds.

[0058] It can be seen that in the related art, the detection of foreign objects during the seat adjustment process is not timely, which may cause damage to the seat function or injury to the passengers. In addition, the detection methods in the related art rely on manual inspection or simple mechanical devices, which cannot realize intelligent automatic detection and cannot achieve effective safety control during the rapid adjustment of the seat slides. Under different environments and usage conditions, the accuracy and stability of foreign object detection are insufficient. The reason is that the integration design of the seat adjustment mechanism and the foreign object detection system in the related art is insufficient, resulting in a large detection delay in foreign object detection. In addition, the foreign object detection process lacks the application of intelligent sensors, which limits the real-time and accuracy of foreign object detection and cannot guarantee the safety of users and seat slides.

[0059] The control method and vehicle for the seat slide provided by the embodiment of the present application are characterized in that a plurality of pressure sensors are provided in the track groove of the seat slide, a transmitting end of a signal sensor is provided at one end of the seat slide, and a receiving end of the signal sensor is provided at the other end. When a seat movement instruction is received, the target area where the foreign object exists is determined based on the pressure signal sent by the pressure sensor; the existence of the target area is verified based on the pressure signal and the photoelectric signal sent by the signal sensor to obtain a verification result; when the verification result is that a foreign object exists, sliding safety control is performed based on the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal. Foreign object detection on the seat slide is performed by jointly detecting the pressure signal and the photoelectric signal, and the accuracy of foreign object detection is improved by jointly detecting the two-dimensional signals. At the same time, the specific scenario where the foreign object exists is reflected based on the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal, and then the dangers caused by the foreign object are avoided through targeted sliding safety control, thereby ensuring the safety of passengers and the seat slide and increasing the service life of the seat slide.

[0060] In some embodiments, a plurality of pressure sensors are provided in the track groove of the seat slide rail, a transmitting end of the signal sensor is provided at one end of the seat slide rail, and a receiving end of the signal sensor is provided at the other end.

[0061] In practice, to reduce the delay in foreign object detection, intelligent sensors are installed on the seat rails. To avoid the potential for erroneous detection and environmental interference that can lead to false detections when using a single sensor, multiple sensors are used to perform foreign object detection. In this embodiment, both a pressure sensor and a signal sensor (such as an infrared beam sensor) are used to detect foreign objects.

[0062] The seat rail includes an upper rail, a lower rail, and a rail motor. The upper rail is fixedly connected to the vehicle seat, and the lower rail is fixedly connected to the vehicle. The rail motor can drive the upper rail to slide relative to the lower rail to achieve forward and backward adjustment of the seat. If there is a foreign object in the rail groove of the seat rail (i.e., the rail groove of the lower rail), it will hinder the upper rail from sliding relative to the lower rail, and the foreign object will also block the space between the upper rail and the lower rail, resulting in an increase in pressure between the upper rail and the lower rail. Therefore, the pressure between the upper rail and the lower rail can be used as a parameter to reflect whether there is a foreign object. Therefore, multiple pressure sensors are set in the rail groove of the seat rail, and the user obtains the pressure of the upper rail and the lower rail of the seat rail in different areas. The pressure sensor can be a distributed thin film pressure sensor (such as a piezoelectric resistor or capacitive sensor), and a group is arranged every 50mm along the inner side of the rail groove (a total of 8-10 pressure detection nodes, each pressure detection node corresponds to a group of pressure sensors).

[0063] The pressure sensor is used to send a pressure signal to the seat controller. The pressure signal corresponds to different signal expressions in different scenarios. For example:

[0064] a. Normal sliding scenario: The pressure signal exhibits a smooth fluctuation curve with an amplitude range of 50-150 kPa (depending on the seat load and calibrable). The frequency is positively correlated with the speed of the upper rail relative to the lower rail (e.g., the pressure signal is stable during uniform movement and exhibits small spikes during acceleration / deceleration).

[0065] b. Foreign body squeezing scene:

[0066] b1. Hard foreign object squeezing scenario, such as the presence of screws, keys, lighters, and other hard foreign objects in the track groove: The pressure signal suddenly rises to a peak pressure greater than or equal to 300kPa (calibratable), but the duration of the peak pressure is short, for example, less than 200ms (calibratable), and the local sensor node in the area where the foreign object is located shows a significant high-pressure area (due to the foreign object occupying the gap), accompanied by a pressure drop at the adjacent nodes.

[0067] b2. In the case of a soft foreign object stuck, such as cloth or paper in the track groove: The pressure signal rises slowly, and the peak value of the pressure signal is generally smaller than the peak value of a hard foreign object. The amplitude range is 150-250 kPa (calibratable), and the duration is long, for example, greater than 500 ms (calibratable). The pressure distribution in the soft foreign object stuck scenario is relatively uniform, but the pressure value changes gradually as the seat slide moves in the direction of movement.

[0068] Therefore, the pressure signal is selected as the signal parameter for determining whether a foreign object exists. At the same time, the characteristics of the pressure signal can also realize the positioning of the foreign object.

[0069] When there is a foreign object inside the seat slide, it will not only cause the pressure between the upper and lower rails to change, but also block the light on the rail. Even translucent foreign objects will cause the duty cycle of the light pulse to change. In order to avoid the accidental use of a single-dimensional pressure signal for foreign object detection, an infrared beam sensor is installed on the seat slide at the same time as the pressure sensor is laid out. The infrared beam sensor includes a transmitter and a receiver. The transmitter emits an invisible infrared beam through an infrared light emitting diode, which is focused by an optical lens to form a directional beam. The receiving end receives the infrared signal by a phototransistor or a photoelectric sensor. When an object completely or partially blocks the light beam (for example, the duration is ≥40ms), the receiving end triggers an alarm signal due to signal interruption. Among them, the seat slide is provided with a transmitting end of the infrared counter-radiation sensor at one end, and a receiving end of the infrared counter-radiation sensor at the other end. When there is a foreign object in the track groove, the light beam emitted by the transmitting end is completely or partially blocked, resulting in the interruption of the light pulse received by the receiving end, thereby realizing the detection of foreign objects in the track groove. Among them, in order to expand the monitoring range of the infrared counter-radiation sensor, when installing the infrared counter-radiation sensor, the distance between the transmitting end and the receiving end is 5mm, and the emission angle is ±15° to cover the 5mm wide area of ​​the seat slide.

[0070] The infrared beam sensor is used to send photoelectric signals to the seat controller. The photoelectric signals correspond to different signal expressions in different scenarios. For example:

[0071] a. Normal state: The receiving end continuously receives complete optical pulses, for example, the duty cycle of the optical pulses is greater than 95% (calibrable).

[0072] b. Presence of foreign matter: The light beam at the transmitting end is blocked by the foreign matter, and the light pulse is interrupted. For example, the duty cycle of the light pulse is less than 50% (calibrable), and the duration of the interruption is proportional to the size of the foreign matter. For example, the interruption time for a foreign matter with a diameter of 5mm is approximately 100-150ms (calibrable).

[0073] Therefore, the photoelectric signal of the infrared beam sensor can also be used as a signal parameter to determine whether a foreign object is present. Using both pressure and photoelectric signals for multi-dimensional foreign object detection can improve the accuracy of foreign object detection.

[0074] The following describes in detail the seat slide rail control method provided by the embodiments of the present application with reference to the accompanying drawings.

[0075] In some embodiments, as Figure 1 As shown, a method for controlling a seat slide rail includes:

[0076] Step 101 : In response to receiving a seat movement instruction, determining a target area where a foreign object exists according to a pressure signal sent by a pressure sensor.

[0077] In specific implementation, when the seat movement signal is received, it indicates that the user has a need to move the seat. At this time, the slide rail motor in the seat slide rail starts, driving the upper rail to move relative to the lower rail. During the movement, the pressure sensor detects the change in the seat slide rail pressure value in real time and sends the obtained pressure signal to the seat controller.

[0078] The presence of foreign matter can be determined based on the pressure value of the pressure signal. Since there is an obvious difference in the pressure values ​​when foreign matter is present and when no foreign matter is present, the pressure value can be used to determine whether foreign matter is present. The pressure signal of the sensor is composed of multiple sensor signals arranged at intervals. Therefore, the pressure signal is expressed as a piecewise function with the vertical axis being the pressure value and the horizontal axis being the time. Each stage of the piecewise function corresponds to a pressure sensor. When the next pressure sensor outputs a valid pressure value (for example, the pressure value is determined to be valid when it is greater than a certain calibration value), the current pressure sensor stops sending the pressure signal, thereby forming a temporally continuous pressure signal.

[0079] When the pressure value of the pressure signal is greater than or equal to the preset first pressure threshold, it can be preliminarily determined that a foreign object exists. However, determining the presence of a foreign object based solely on a single large pressure value is accidental. In order to reduce errors, the gradient pressure difference over a period of time is calculated and verified with the maximum pressure, and the pressure signal within a certain period of time is acquired in the form of a pressure signal window. For example, taking the motor-driven moving seat as a uniform speed process, and taking the example of one unit time = sliding speed / sensor spacing, the window width of the pressure signal window (the width between the start and end points of the pressure signal window) can be selected to be the width of two unit times, wherein the end point of the pressure signal window is the real-time acquired pressure signal, that is, the pressure signal window slides along with the real-time acquired pressure signal, and the window includes the pressure signal at the current moment and the previous two time units.

[0080] When determining the target area where a foreign object is present based on the pressure signal transmitted by the pressure sensor, the system first intercepts the pressure signal within the current moment and the previous two time units according to a preset pressure signal window to obtain a local pressure signal; wherein the pressure signal window includes at least two sensor signals. Then, the maximum and minimum pressures of the local pressure signal intercepted within the pressure signal window are determined, and the difference between the maximum and minimum pressures is determined as the gradient pressure difference.

[0081] If the gradient pressure difference is greater than or equal to the preset difference threshold, a significant pressure increase has occurred, indicating the presence of a foreign object within the seat rail, causing the pressure increase. Furthermore, if the maximum pressure is greater than or equal to the first pressure threshold, this indicates that the pressure increase is indeed due to the foreign object, eliminating any misjudgment due to a small pressure increase caused by seat vibration. The two dimensions of judgment mutually verify each other, ensuring the accuracy of the judgment results. Therefore, if the gradient pressure difference is greater than or equal to the preset difference threshold and the maximum pressure is greater than or equal to the preset first pressure threshold, a foreign object is determined to be present. At this point, the target position can be further determined based on the pressure signal window.

[0082] When determining the target position based on the pressure signal window, first, it is necessary to determine the first pressure signal and the last pressure signal corresponding to the pressure signal window; among them, the first pressure signal is the signal at the starting position of the pressure signal window, and the last pressure signal is the signal at the end position of the pressure signal window, and the last pressure signal is the pressure signal collected in real time.

[0083] Then, the first pressure sensor that sends the first pressure signal and the second pressure sensor that sends the last pressure signal are determined. Since the pressure signal window includes the detection range of the two pressure sensors, when the local pressure signal indicates the presence of foreign matter, it means that the location of the foreign matter is within the detection range of at least two pressure sensors corresponding to the pressure signal window. The first installation position of the first pressure sensor is determined as the starting position of the upper boundary of the area, and the second installation position of the second pressure sensor is determined as the starting position of the lower boundary of the area; and the area between the upper boundary position and the lower boundary position of the area is determined as the target area, thereby realizing the preliminary positioning of the foreign matter.

[0084] Step 102: Verify the existence of the target area according to the pressure signal and the photoelectric signal sent by the signal sensor to obtain a verification result.

[0085] During specific implementation, in order to avoid the problem of randomness in single signal detection and to improve the credibility of foreign body detection results, the photoelectric signal sent by the infrared counter-radiation sensor is used to verify the existence of the target area. When verifying the existence of the target area based on the pressure signal and the photoelectric signal sent by the infrared counter-radiation sensor, the signal start time and signal end time corresponding to the target area are first determined based on the pressure signal; only the pressure signal and the photoelectric signal within the same time period can verify each other, so it is necessary to determine the time range corresponding to the pressure signal window, and determine the acquisition time corresponding to the starting point of the pressure signal window as the signal start time, and determine the acquisition time corresponding to the end point of the pressure signal window as the signal end time, wherein the signal start time and the signal end time change dynamically with the sliding of the pressure signal window.

[0086] Then, a photoelectric signal time window is constructed based on the signal start time and signal end time; that is, the signal start time is used as the starting point of the time window, and the signal end time is used as the end point of the time window to obtain the photoelectric signal time window. After obtaining the photoelectric signal time window, the target area is verified based on the photoelectric signal within the photoelectric signal time window. If there is a light pulse interruption within the photoelectric signal time window, it means that the light beam emitted by the infrared counter-radiation sensor's transmitting end is blocked, resulting in a signal interruption at the receiving end, indicating that there is a foreign object in the track, and the presence of foreign object is determined as the verification result. If there is no light pulse interruption within the photoelectric signal time window, it means that the light beam emitted by the infrared counter-radiation sensor's transmitting end is not blocked, and light is fully transmitted between the transmitting end and the receiving end, indicating that there is no foreign object in the track, and the absence of foreign object is determined as the verification result.

[0087] The target area is verified through the photoelectric signal of the infrared counter-radiation sensor, realizing the comprehensive detection of two dimensions of pressure signal and photoelectric signal, ensuring the accuracy of foreign body detection results.

[0088] Step 103: In response to the verification result that a foreign object exists, sliding safety control is performed according to the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal.

[0089] In specific implementation, if the verification result is that there is a foreign object, it means that the judgment results of the pressure signal and the photoelectric signal are consistent, and both determine that there is a foreign object on the seat slide rail. At this time, it is necessary to determine the specific scenario where the foreign object exists based on the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal. For example, all scenarios can be divided into 4 categories:

[0090] The first type of scenario is a normal sliding scenario. The pressure signal characteristic of the pressure signal is that the pressure value fluctuates smoothly around a fixed pressure value, and the photoelectric signal characteristic of the photoelectric signal is that the light is fully transmitted, confirming that there is no foreign object in the track and the pressure value fluctuates slightly.

[0091] The second scenario is the vibration interference scenario. The pressure signal characteristic of the pressure signal is a small increase in the pressure value. At the same time, the photoelectric signal characteristic of the photoelectric signal is full light transmission or short-term light pulse interruption. This is a misjudgment caused by intense vibration or accidental touch, and it is determined that there is no foreign object in the track.

[0092] The third scenario is the presence of hard foreign matter. Since hard foreign matter is less compressible, when the seat slide squeezes the hard foreign matter, the pressure value rises sharply in a short period of time. The pressure signal characteristic of the pressure signal is that the pressure value suddenly rises to a larger value. At the same time, if the hard foreign matter is not transparent, the light beam at the transmitting end will be blocked, resulting in a long period of light pulse interruption. If the hard foreign matter is transparent, the duty cycle of the light beam at the transmitting end will be reduced, which will also cause the photoelectric signal to show a long period of light pulse interruption. In this case, the pressure signal characteristic is that the pressure value rises sharply in a short period of time. When the photoelectric signal characteristic of the photoelectric signal is a long period of light pulse interruption, it is determined that a hard foreign matter exists.

[0093] The fourth scenario is the presence of soft foreign matter. Since hard foreign matter is more compressible, when the seat slide squeezes the soft foreign matter, the pressure value slowly increases to a larger value. The pressure signal characteristic of the pressure signal is that the pressure value slowly increases to a larger value. At the same time, if the soft foreign matter is not transparent, the light beam at the transmitting end will be blocked, resulting in a long period of light pulse interruption. If the soft foreign matter is transparent, the duty cycle of the light beam at the transmitting end will be reduced, which will also cause the photoelectric signal to show a long period of light pulse interruption. In this case, the pressure signal characteristic is that the pressure value slowly increases to a larger value. When the photoelectric signal characteristic of the photoelectric signal is a long period of light pulse interruption, it is determined that a soft foreign matter exists.

[0094] When the verification result shows that foreign matter exists, it means that the normal sliding scenario has been filtered out, and it is necessary to continue to distinguish between the scenarios of hard foreign matter, soft foreign matter and vibration interference based on the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal, and apply targeted sliding safety control to different scenarios. Through targeted sliding safety control, the dangers caused by foreign matter can be avoided, the safety of passengers and seat rails can be ensured, and the service life of the seat rails can be increased.

[0095] In summary, the seat rail control method provided in the embodiments of the present application uses both pressure and photoelectric signals to detect foreign objects in the seat rail. This dual-dimensional signal detection improves the accuracy of foreign object detection. Furthermore, the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal reflect the specific scenario in which the foreign object is present. Targeted sliding safety control can then be used to mitigate the dangers posed by foreign objects, ensuring the safety of passengers and the seat rail, and extending the service life of the seat rail.

[0096] In some embodiments, as Figure 2 As shown, the control method of the seat slide rail further includes:

[0097] Step 201: In response to not receiving a seat movement instruction, determining a static interruption time of a photoelectric signal.

[0098] In specific implementation, if the seat movement instruction is not received, the seat will not move, and the upper rail will not move relative to the lower rail. The pressure value in the pressure signal is 0 or a fixed value, so the pressure signal cannot be used to judge the foreign object at this time. At this time, only the photoelectric signal can be used to judge the foreign object. The principle of photoelectric signal judgment of whether there is a foreign object is that the foreign object blocks the light beam emitted by the transmitter. When the foreign object completely or partially blocks the light beam, the receiving end is interrupted by the signal. The photoelectric signal characteristic of the photoelectric signal is the light pulse interruption. In order to avoid misjudgment caused by changes in the duty cycle of the light beam received by the receiving end due to environmental reasons, when the seat is static, the static interruption time of the light pulse interruption is determined to determine whether the light pulse interruption in the photoelectric signal is valid based on the static interruption time.

[0099] Step 202 : In response to the static interruption time being less than or equal to a preset first time threshold, determining that there is no foreign object in the seat slide rail.

[0100] In specific implementation, if the static interruption time is less than or equal to the preset first time threshold, it means that the light pulse interruption is caused by accidental misjudgment and is an invalid signal. The light pulse interruption can be ignored and it is determined that there is no foreign object in the seat slide rail.

[0101] Step 203 : In response to the static interruption time being greater than a preset first time threshold, it is determined that a foreign object exists in the seat slide rail.

[0102] In specific implementation, if the static interruption time is greater than the preset first time threshold, it means that the photoelectric signal characteristic is in the light pulse interruption state for a long time, which is consistent with the situation that the light beam at the transmitting end is blocked by foreign matter, indicating that there is foreign matter in the seat slide rail.

[0103] When the seat is static, foreign objects in the seat rail are detected through photoelectric signals, which improves the applicable scenarios of foreign object detection. An alarm is issued when the seat is static to avoid danger caused by foreign objects when the seat is moving.

[0104] In some embodiments, as Figure 3 As shown, the target area where the foreign matter exists is determined based on the pressure signal sent by the pressure sensor, including:

[0105] Step 301: Determine the effective pressure signal after the seat moves in the pressure signal, intercept the effective pressure signal according to a preset pressure signal window, and obtain a local pressure signal. The pressure signal window includes at least two sensor signals.

[0106] In a specific implementation, taking the example of one unit time = sliding speed / sensor spacing, and the example of a pressure signal window width of two units of time, when determining the target area where a foreign object is present based on the pressure signal sent by the pressure sensor, the first timestamp when the vehicle executes the seat movement command is first determined, and the signal in the pressure signal after the first timestamp is determined as a valid pressure signal. This is because the pressure signal is only suitable for foreign object detection when the seat is in motion, and the pressure signal when the seat is static is difficult to reflect the presence of foreign objects. After determining the valid pressure signal, the pressure signal within the current time and the previous two time units is intercepted according to a preset pressure signal window. The end point of the pressure signal window is aligned with the current time, and the interception value is the time point at which the starting point of the pressure signal window is located. The interception range of the pressure signal window is the pressure signal within the historical two units of time, thus obtaining the local pressure signal within the two units of time. Since one time unit corresponds to one sensor signal, and the width of the pressure signal window is two units of time, only when the end point of the pressure signal window is the end point of the sensor signal are there two sensor signals within the pressure signal window. In other cases, there are three sensor signals within the pressure signal window.

[0107] Step 302: Determine the maximum pressure and the minimum pressure in the local pressure signal, and determine the difference between the maximum pressure and the minimum pressure as the gradient pressure difference.

[0108] In specific implementation, after obtaining the local pressure signal, the maximum and minimum pressures are determined in the local pressure signal. The maximum pressure value is the pressure value at the highest peak of the local pressure signal, and the maximum pressure value is the pressure value at the lowest trough of the local pressure signal. The difference between the maximum and minimum pressures is then determined as the gradient pressure difference. This is because if there is a foreign object in the seat rail and the upper rail moves relative to the lower rail, the local sensor nodes in the area where the foreign object is located will appear as a significantly high-pressure area (due to the foreign object occupying the gap, causing a significant increase in pressure), accompanied by a decrease in pressure at adjacent nodes. Therefore, the gradient pressure difference between the maximum and minimum pressures is selected to determine whether a foreign object is actually present.

[0109] Step 303: In response to the gradient pressure difference being greater than or equal to a preset difference threshold, and the maximum pressure being greater than or equal to a preset first pressure threshold, determining a target position according to an endpoint position of the pressure signal window.

[0110] In specific implementations, if the gradient pressure difference is greater than or equal to a preset difference threshold, it indicates a significant increase in pressure in the local area, indicating the presence of a foreign object within the seat rail, causing the pressure increase. Furthermore, if the maximum pressure is greater than or equal to the first pressure threshold, this indicates that the pressure increase is indeed due to the foreign object, eliminating misjudgments resulting from a small pressure increase caused by seat vibration. The two dimensions of judgment mutually verify each other, ensuring the accuracy of the judgment results. Therefore, the presence of a foreign object is determined when the gradient pressure difference is greater than or equal to the preset difference threshold and the maximum pressure is greater than or equal to the preset first pressure threshold. Once the presence of a foreign object is determined, the target position can be further determined based on the endpoint position of the pressure signal window. This determination process is described in the following embodiment.

[0111] In some embodiments, the endpoint position includes a starting position and an end position; determining the target position according to the endpoint position of the pressure signal window includes:

[0112] Step 3031: Determine a first pressure signal corresponding to the starting position and a last pressure signal corresponding to the ending position.

[0113] In specific implementations, when determining the target position based on the pressure signal window, it is first necessary to determine the first and last pressure signals corresponding to the pressure signal window. The first pressure signal is the sensor signal at the starting point of the pressure signal window, and the last pressure signal is the sensor signal at the end point of the pressure signal window. Since each sensor signal corresponds to a group of sensors, and each group of sensors corresponds to a location on the seat rail, determining the first and last pressure signals is equivalent to determining two locations on the seat rail. Based on these two locations, the corresponding acceptable area on the seat rail can be determined.

[0114] Step 3032: Determine the first pressure sensor that sends the first pressure signal, and determine the first installation position of the first pressure sensor as the starting position of the upper boundary of the area.

[0115] In specific implementation, since the pressure signal window includes the detection range of two pressure sensors, when the local pressure signal indicates the presence of foreign matter, it means that the location of the foreign matter is within the detection range of at least two pressure sensors corresponding to the pressure signal window, and the first installation position of the first pressure sensor that sends the first pressure signal is a boundary position of the target area. Therefore, after determining the first pressure signal, the first pressure sensor that sends the first pressure signal is determined, and the first installation position of the first pressure sensor is determined as the starting position of the upper boundary of the area.

[0116] Step 3033: Determine the second pressure sensor that sends the final pressure signal, and determine the second installation position of the second pressure sensor as the starting position of the lower boundary of the area.

[0117] In specific implementation, since the pressure signal window includes the detection range of two pressure sensors, when the local pressure signal indicates the presence of foreign matter, it means that the location of the foreign matter is within the detection range of at least two pressure sensors corresponding to the pressure signal window, and the second installation position of the second pressure sensor that sends the last pressure signal is another boundary position of the target area. Therefore, after determining the last pressure signal, the second pressure sensor that sends the last pressure signal is determined, and the second installation position of the second pressure sensor is determined as the starting position of the lower boundary of the area.

[0118] Step 3034: Determine the area between the upper boundary position and the lower boundary position of the area as the target area.

[0119] In a specific implementation, once the upper and lower boundaries of the target area are determined, the area between these two boundaries is the target area. Therefore, the area between the upper and lower boundaries is determined as the target area. Because a single pressure signal can misjudge the presence of a foreign object, to reduce this possibility, a photoelectric signal is used to verify the target area. The verification process is shown in the following embodiment.

[0120] In some embodiments, as Figure 4 As shown, the existence of the target area is verified based on the pressure signal and the photoelectric signal sent by the signal sensor, and the verification results are obtained, including:

[0121] Step 401: Determine the signal start time and signal end time corresponding to the target area according to the pressure signal.

[0122] In specific implementation, when a foreign object actually exists, the photoelectric signal characteristics and pressure signal characteristics within the same time period both show the presence of a foreign object, so the photoelectric signal and the pressure signal are synchronously correlated in time. After the pressure signal determines that a foreign object exists and that there is a possible area, in order to avoid the problem of randomness in single signal detection and to improve the credibility of the foreign object detection results, the photoelectric signal sent by the infrared counter-radiation sensor is used to verify the existence of the target area. When verifying the existence of the target area based on the pressure signal and the photoelectric signal sent by the infrared counter-radiation sensor, the signal start time and signal end time corresponding to the target area are first determined based on the pressure signal; only the pressure signal and the photoelectric signal within the same time period can verify each other, so it is necessary to determine the time range corresponding to the pressure signal window, and determine the acquisition time corresponding to the starting point of the pressure signal window as the signal start time, and determine the acquisition time corresponding to the end point of the pressure signal window as the signal end time, wherein the signal start time and the signal end time change dynamically with the sliding of the pressure signal window.

[0123] Step 402: Construct a photoelectric signal time window according to the signal start time and the signal end time.

[0124] In specific implementation, since the photoelectric signal and the pressure signal are synchronized in time, the signal start time is taken as the starting point of the time window, and the signal end time is taken as the end point of the time window to obtain the photoelectric signal time window.

[0125] Step 403: In response to the presence of a light pulse interruption in the photoelectric signal within the photoelectric signal time window, determining the presence of a foreign object as a verification result.

[0126] In specific implementation, after obtaining the photoelectric signal time window, the target area is verified based on the photoelectric signal within the photoelectric signal time window. If there is a light pulse interruption within the photoelectric signal time window, it means that the light beam emitted by the transmitting end of the infrared counter-radiation sensor is blocked, resulting in a signal interruption at the receiving end, indicating that there is a foreign object in the track, and the presence of foreign matter is determined as the verification result.

[0127] Step 404: In response to the absence of light pulse interruption in the photoelectric signal within the photoelectric signal time window, determining that there is no foreign object as a verification result.

[0128] During specific implementation, if there is no light pulse interruption in the photoelectric signal within the photoelectric signal time window, it means that the light beam emitted by the transmitting end of the infrared counter-radiation sensor is not blocked, and light is fully transmitted between the transmitting end and the receiving end, indicating that there is no foreign object in the track, and the absence of foreign object is determined as the verification result.

[0129] The target area is verified through the photoelectric signal of the infrared counter-radiation sensor, realizing the comprehensive detection of two dimensions of pressure signal and photoelectric signal, ensuring the accuracy of foreign body detection results.

[0130] In some embodiments, as Figure 5 As shown, sliding safety control is performed according to the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal, including:

[0131] Step 501: Determine an initial control scenario based on the pressure signal characteristics, and determine a current control scenario based on the photoelectric signal characteristics and the initial control scenario.

[0132] During specific implementation, when the verification result shows that foreign matter exists, it means that the normal sliding scenario has been filtered out, and it is necessary to continue to distinguish between the scenarios of hard foreign matter, soft foreign matter and vibration interference based on the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal, and apply targeted sliding safety control to different scenarios. Through targeted sliding safety control, the dangers brought by foreign matter can be avoided, the safety of passengers and seat rails can be ensured, and the service life of the seat rails can be increased.

[0133] In some embodiments, determining an initial control scenario based on pressure signal characteristics includes:

[0134] Step 5011: In response to the pressure signal characteristic within the pressure signal window being that the maximum pressure is greater than a preset second pressure threshold, the presence of a hard foreign object is determined as an initial control scenario.

[0135] During specific implementation, when determining the target area, it has been determined that the pressure value is greater than the first pressure threshold (for example, 200kPa), indicating that there is already a foreign body. The biggest difference between the presence of hard foreign bodies and the presence of soft foreign bodies in terms of pressure signals is the size of the pressure value, so a second pressure threshold greater than the first pressure threshold is selected to distinguish between hard foreign bodies and soft foreign bodies. When the pressure signal characteristic in the pressure signal window is that the maximum pressure is greater than the preset second pressure threshold (for example, 350kPa), the presence of a hard foreign body is determined as the initial control scenario.

[0136] Step 5012: In response to the pressure signal characteristic within the pressure signal window being that the maximum pressure is less than or equal to a preset second pressure threshold, determining the presence of a soft foreign object as an initial control scenario.

[0137] In a specific implementation, when the pressure signal characteristic in the pressure signal window is that the maximum pressure is less than or equal to the preset second pressure threshold, it indicates that the presence of foreign matter will not generate a large pressure, and the presence of soft foreign matter is determined as the initial control scenario.

[0138] That is, when the pressure characteristic signal is a pressure value ≥ 350kPa, the presence of a hard foreign body is determined as the initial control scenario. When the pressure characteristic signal is 350kPa ≥ a pressure value ≥ 200kPa, the presence of a soft foreign body is determined as the initial control scenario. Further verification can be performed using the pressure change rate, that is, when the maximum pressure is greater than the preset second pressure threshold, and the pressure increase rate is greater than the preset first rate threshold, the presence of a hard foreign body is determined as the initial control scenario. When the maximum pressure is less than or equal to the preset second pressure threshold, the pressure increase rate is greater than the preset second rate value, and the pressure increase rate is less than or equal to the preset first rate threshold, the presence of a soft foreign body is determined as the initial control scenario.

[0139] After the initial control scene is determined, in order to avoid misjudgment, it is necessary to further determine the current control scene based on the photoelectric signal characteristics and the initial control scene. The process is as follows:

[0140] In some embodiments, determining the current control scenario based on the photoelectric signal characteristics and the initial control scenario includes:

[0141] Step 5013: Determine the duration of the optical pulse interruption of the photoelectric signal within the photoelectric signal time window according to the photoelectric signal characteristics.

[0142] In specific implementations, a short interruption of the light pulse may be caused by the obstruction of the light beam due to environmental influences, such as a scene where an insect passes by the light beam, while a long interruption of the light pulse can determine the presence of a substantial foreign object.

[0143] Step 5014: In response to the initial control scenario being the presence of hard foreign matter, and the light pulse interruption duration being greater than or equal to a preset first duration threshold, the presence of hard foreign matter is determined as the current control scenario.

[0144] In specific implementation, when the initial control scenario is the presence of hard foreign matter, if the light pulse interruption duration is greater than or equal to the preset first duration threshold, it indicates that there is actually a hard foreign matter, the pressure signal feature is valid, and the presence of a hard foreign matter is determined as the current control scenario.

[0145] Step 5015: In response to the initial control scenario being the presence of a hard foreign object and the light pulse interruption duration being less than a preset first duration threshold, vibration interference is determined as the current control scenario.

[0146] During specific implementation, when the initial control scenario is that there is a hard foreign object, if the light pulse interruption duration is less than the preset first duration threshold, it means that there is no hard foreign object, or the hard foreign object is ejected from the track when the seat slide moves, has left the track, and will no longer affect the seat slide. The pressure signal feature is determined to be invalid, and vibration interference is determined as the current control scenario.

[0147] Step 5016: In response to the initial control scenario being the presence of a soft foreign object, and the light pulse interruption duration being greater than or equal to a preset first duration threshold, determining the presence of a soft foreign object as the current control scenario.

[0148] In specific implementation, when the initial control scenario is the presence of soft foreign matter, if the light pulse interruption duration is greater than or equal to the preset first duration threshold, it indicates that there is actually a soft foreign matter, the pressure signal feature is valid, and the presence of a soft foreign matter is determined as the current control scenario.

[0149] Step 5017: In response to the initial control scenario being the presence of a soft foreign object and the light pulse interruption duration being less than a preset first duration threshold, vibration interference is determined as the current control scenario.

[0150] During specific implementation, when the initial control scenario is the presence of soft foreign matter, if the light pulse interruption duration is less than the preset first duration threshold, it means that there is no soft foreign matter, or the soft foreign matter is very small and will not continue to have an immediate impact on the seat slide rail. The pressure signal feature is determined to be invalid, and vibration interference is determined as the current control scenario.

[0151] Based on the pressure signal characteristics of the pressure signal and the photoelectric signal characteristics of the photoelectric signal, the scenarios of hard foreign objects, soft foreign objects and vibration interference are distinguished, and targeted sliding safety control is applied to different scenarios. Through targeted sliding safety control, the dangers caused by foreign objects are avoided, the safety of passengers and seat slides is ensured, and the service life of the seat slides is increased.

[0152] Step 502: Perform sliding safety control according to the current control scenario.

[0153] In some embodiments, performing sliding safety control according to the current control scenario includes:

[0154] Step 5021: In response to the current control scenario that a hard foreign object exists, the slide rail motor is controlled to stop immediately, the mechanical locking device is controlled to fix the current slide rail position, and an alarm is issued according to the target area.

[0155] During specific implementation, if the current control scenario is that there is a hard foreign object, if the slide rail motor continues to run, excessive pressure may damage the seat slide rail, so the slide rail motor is controlled to stop immediately at this time, and prevent the upper rail from continuing to slide relative to the lower rail due to the user's weight, and control the mechanical locking device to fix the current slide rail position, and additionally fix the seat slide rail position. At the same time, the location of the foreign object is displayed according to the target area on the central control display screen, and the user is informed by voice prompts to clean the hard foreign objects in the target area, providing location guidance for the user to manually remove the foreign object to ensure the safety of the seat slide rail.

[0156] Step 5022: In response to the current control scenario that a soft foreign object exists, the slide rail motor is controlled to decelerate and stop, and an alarm is issued according to the target area.

[0157] In specific implementation, if the current control scenario indicates the presence of a soft foreign object, the gradually increasing pressure on the slide rail could damage the seat rail if the slide rail motor continues to operate. Therefore, the slide rail motor is controlled to slow down and stop, ensuring the user's riding experience while preventing excessive pressure from damaging the slide rail. Simultaneously, the central control display screen indicates the location of the foreign object based on the target area, and a voice prompt informs the user to clear the soft foreign object from the target area, providing location guidance for manual removal of the foreign object to ensure the safety of the seat rail.

[0158] Step 5023: In response to the current control scenario being vibration interference, a slide rail inspection prompt is performed according to the target area.

[0159] During specific implementation, if the current control scenario is vibration interference, it means that the judgment results of the pressure signal and the photoelectric signal are inconsistent. At this time, the location of the foreign object is directly displayed on the central control display screen according to the target area, and the user is informed by voice prompts that there may be foreign objects in the target area, and the location guidance is provided for the user to manually remove the foreign object, so that the user can manually confirm whether there is a foreign object, avoid the impact of incorrect judgment, and ensure the user experience.
