[0022] Here, exemplary embodiments will be described in detail, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0023] The block diagrams shown in the accompanying drawings are merely functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities may be implemented in software form, or in one or more hardware modules or integrated circuits, or in different networks and / or processor devices and / or microcontroller devices.

[0024] The flowcharts shown in the accompanying drawings are only exemplary and do not necessarily include all the contents and operations / steps, nor must they be executed in the order described. For example, some operations / steps can be decomposed, and some operations / steps can be combined or partially combined, so the actual execution order may change according to actual conditions.

[0025] The term "multiple" as used in this application refers to two or more than two. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0026] In the related art, vehicles may be equipped with a seat anti-pinch function to prevent passengers or other objects from being accidentally pinched when the seat is adjusted. However, if the seat anti-pinch function is misjudged, the seat may not be adjusted normally. Therefore, the accuracy of the seat anti-pinch judgment is extremely important.

[0027] For example, when the seat anti-pinch function is turned on, when the seat is adjusted and moved toward the front of the vehicle, if it is misjudged that the seat may clamp the corresponding obstacle when moving forward, the seat will most likely move backward. However, since the driver and passengers have determined based on the actual situation that the seat will not clamp the corresponding obstacle when moving forward, they can only continue to adjust the seat to move toward the front of the vehicle. At this time, the seat will move forward under the operation of the driver and passengers, and then automatically move backward according to the seat anti-pinch function, and this will happen again and again, eventually resulting in the driver and passengers being unable to adjust the seat to the corresponding position.

[0028] Based on this, combined Figures 1 to 4As shown, the embodiments of the present application respectively provide a vehicle seat anti-pinch control method, a vehicle seat anti-pinch control device 300, a vehicle, a computer-readable storage medium, and a computer program product to solve the above problems. These embodiments will be described in detail below.

[0029] In an exemplary embodiment of the present application, Figure 1 The flowchart of steps S210-S230 of a vehicle seat anti-pinch control method provided by an embodiment of the present application is shown, and the method is executed by a vehicle terminal or a seat controller. Figure 1 As shown, the method includes steps S210 to S230, which are described in detail as follows:

[0030] Step S210: Acquire operating information of the seat motor, where the operating information includes at least one of the rotation speed change information of the seat motor, the current change information of the seat motor, the voltage change information of the seat motor, and the temperature change information of the seat motor.

[0031] The rotation speed change information of the seat motor, the current change information of the seat motor, the voltage change information of the seat motor and the temperature change information of the seat motor can be obtained through corresponding sensors arranged in the seat.

[0032] Step S220: If the working information of the seat motor meets the pre-start condition of the seat anti-pinch function, the seat status information is obtained, and the status information includes at least one of the seat pressure change information, the seat motor displacement change information, the seat occupancy information and the obstacle information around the seat.

[0033] After obtaining the working information of the seat motor, it is necessary to further determine whether the working information of the seat motor meets the pre-starting condition of the seat anti-pinch function, so as to pre-determine whether the seat needs to start the seat anti-pinch function. If not, the seat anti-pinch function will not be started. If it is satisfied, the seat status information will be used to finally decide whether to start the seat anti-pinch function.

[0034] In an exemplary embodiment of the present application, the method steps for determining whether the working information of the seat motor meets the pre-starting conditions of the seat anti-pinch function include: determining the speed value of the seat motor based on the speed change information of the seat motor; if the speed value of the seat motor is less than the speed threshold, determining that the working information of the seat motor meets the pre-starting conditions of the seat anti-pinch function.

[0035] In an exemplary embodiment of the present application, the method step of determining whether the working information of the seat motor meets the pre-starting condition of the seat anti-pinch function further includes: determining the speed value of the seat motor, the current value of the seat motor, the voltage change value of the seat motor and the temperature change value of the seat motor respectively based on the speed change information of the seat motor, the current change information, the voltage change information of the seat motor and the temperature change information of the seat motor; if the speed value of the seat motor is less than the speed threshold, the current value of the seat motor is greater than the current threshold, the temperature change value of the seat motor is greater than the temperature change threshold and the voltage change value of the seat motor is greater than the voltage change threshold, then it is determined that the working information of the seat motor meets the pre-starting condition of the seat anti-pinch function. Among them, the speed threshold, the current threshold, the temperature change threshold and the preset range of voltage change can be obtained according to calibration test.

[0036] When the speed value of the seat motor is less than the speed threshold, it means that the seat is about to get stuck or has already gotten stuck and cannot continue to rotate at a normal speed, which causes the motor speed value to be less than the speed threshold. Next, if the current of the seat motor will increase (for example, the current value of the seat motor is greater than the current threshold), it means that after the motor speed of the seat motor is forced to decrease (for example, after the speed value of the seat motor is less than the speed threshold), an obstacle that hinders the seat adjustment appears, and the forward movement of the seat is hindered (because under normal circumstances, when the motor speed of the drive motor is actively controlled by the PWM signal to decrease, the current of the seat motor will not suddenly increase). Therefore, when the speed value of the seat motor is less than the speed threshold and the current value of the seat motor is greater than the current threshold, it is likely that the seat is about to be stuck by a foreign object. In addition, the seat adjustment is generally driven by a constant voltage and the temperature change of the seat motor is generally also a uniform change. Therefore, if the voltage change value of the seat motor suddenly increases (for example, the voltage change value of the seat motor is greater than the voltage change threshold) and the temperature suddenly increases (for example, the temperature change value of the seat motor is greater than the temperature change threshold), it can be further explained that the seat is likely to be stuck by a foreign object. At this time, it can be determined that the working information of the seat motor meets the pre-start condition of the seat anti-pinch function. On the contrary, if the speed value of the seat motor is not less than the speed threshold, the current value of the seat motor is not greater than the current threshold, the temperature change value of the seat motor is not greater than the temperature change threshold, and the voltage change value of the seat motor is not greater than the voltage change threshold, it is determined that the working information of the seat motor does not meet the pre-start condition of the seat anti-pinch function.

[0037] In an exemplary embodiment of the present application, the method steps for obtaining the status information of the seat include: a mesh point pressure sensor can be pre-buried under the seat surface to monitor the pressure distribution signal value of each point in real time. When the pressure sensor is subjected to external compression, the output pressure distribution signal will change, thereby obtaining the pressure change information of the seat. The displacement change information of the seat motor can be obtained through a displacement sensor, wherein the displacement sensor does not use the Hall change or ripple change of the drive motor, but uses the redundant design of an optical displacement sensor or a resistive displacement sensor to determine whether the seat is displaced by the change of the optical signal or the resistive signal. The seat occupancy information can be effectively determined by combining an infrared sensor with a pressure sensor to determine whether there is a person or object on the seat, thereby obtaining the seat occupancy information.

[0038] Voltage sensors and temperature sensors are mainly used to identify the working environment of the motor. The relevant data can be used for voltage and temperature compensation. Each sensor collects seat status data in real time, including but not limited to passenger weight, seat position changes, obstacle detection and motor current.

[0039] Step S230: Determine whether to activate the seat anti-pinch function based on the matching relationship between the seat status information and the preset status information.

[0040] In the present application, the anti-pinch control method of the vehicle seat can first obtain the working information of the seat motor (the working information includes at least one of the speed change information of the seat motor, the current change information of the seat motor, the voltage change information of the seat motor, and the temperature change information of the seat motor) during the process of the user adjusting the seat, and then determine whether the seat meets the pre-start condition of the seat anti-pinch function based on the working information of the seat motor. If it does, the state information of the seat is obtained again, and then it is determined whether to start the seat anti-pinch function based on the state information of the seat (the state information includes at least one of the pressure change information of the seat, the displacement change information of the seat motor, the seat occupancy information, and the obstacle information around the seat). Therefore, by combining the working information of the seat motor and the state information of the seat to determine whether to control the pre-start condition of the seat anti-pinch function, it is possible to reduce false alarms, avoid unnecessary misoperations, improve the comfort and safety of passengers, and ultimately significantly improve the accuracy of the seat anti-pinch judgment.

[0041] In an exemplary embodiment of the present application, the status information includes obstacle information around the seat, and the steps of determining whether to activate the seat anti-pinch function based on the matching relationship between the seat status information and the preset status information include: if it is determined that there is an obstacle in the anti-pinch direction of the seat based on the obstacle information around the seat, then determining that the seat status information matches the preset status information, and determining to activate the seat anti-pinch function based on the matching between the seat status information and the preset status information.

[0042] When the working information of the seat motor meets the pre-starting conditions of the seat anti-pinch function, it can be decided whether to start the seat anti-pinch function by judging whether there is an obstacle in the anti-pinch direction of the seat, thereby improving the start accuracy of the seat anti-pinch function.

[0043] In an exemplary embodiment of the present application, the status information includes seat occupancy information, and the method for determining whether to activate the seat anti-pinch function based on the matching relationship between the seat status information and preset status information also includes: determining that the seat is occupied based on the occupancy information around the seat, then determining that the seat status information matches the preset status information, and determining to activate the seat anti-pinch function based on the matching between the seat status information and the preset status information.

[0044] When the working information of the seat motor meets the pre-start conditions of the seat anti-pinch function, it can also be determined whether to start the seat anti-pinch function by judging whether there are obstacles in the anti-pinch direction of the seat and / or whether the seat is occupied, thereby improving the accuracy of starting the seat anti-pinch function.

[0045] In an exemplary embodiment of the present application, the status information includes pressure change information of the seat and displacement change information of the seat motor, and the step method for determining that the status information of the seat matches the preset status information also includes: determining that there is a displacement change of the seat motor based on the displacement change information of the seat motor, and determining that there is a sudden pressure change at the pressure distribution point of the seat in the anti-pinch direction based on the pressure change information of the seat, and then determining that the status information of the seat matches the preset status information.

[0046] When the working information of the seat motor meets the pre-start conditions of the seat anti-pinch function, if it is determined that there is a displacement change in the seat motor, and based on the pressure change information of the seat, it is determined that there is a sudden change in pressure at the pressure distribution point of the seat in the anti-pinch direction, then it can be determined with a high probability that an object may be against the seat during the adjustment process, and then it can be determined that the seat may have clamped an object during the movement. At this time, it can be determined that the seat status information matches the preset status information, and then the seat anti-pinch function can be activated.

[0047] In an exemplary embodiment of the present application, the status information includes obstacle information around the seat, seat occupancy information, seat pressure change information and seat motor displacement change information. The method for determining whether to start the seat anti-pinch function based on the matching relationship between the seat status information and preset status information includes: if it is determined that there is no obstacle in the anti-pinch direction of the seat and / or the seat is not occupied, and it is determined that there is no displacement change in the seat motor and it is determined that there is no pressure mutation at the pressure distribution point of the seat in the anti-pinch direction, then it is determined that the seat status information does not match the preset status information; based on the mismatch between the seat status information and the preset status information, it is determined that the seat anti-pinch function is not started.

[0048] When the working information of the seat motor meets the pre-starting condition of the seat anti-pinch function, if it is also satisfied that there is no obstacle in the anti-pinch direction of the seat and / or it is determined that the seat is not occupied, and it is determined that there is no displacement change of the seat motor and it is determined that there is no sudden pressure change at the pressure distribution point of the seat in the anti-pinch direction, then it means that there is a misjudgment when judging whether the seat anti-pinch function is started based on the working information of the seat motor, and the seat anti-pinch function is not started at this time. Therefore, the probability of the seat anti-pinch function being started by mistake can be reduced.

[0049] In an exemplary embodiment of the present application, the anti-pinch control method of a vehicle seat also includes: if the working information of the seat motor meets the pre-start condition of the seat anti-pinch function, and the status information of the seat determines that the seat does not start the anti-pinch function, then the seat status information and the working information of the seat motor are recorded.

[0050] When the working information of the seat motor meets the pre-start conditions of the seat anti-pinch function, and the seat status information determines that the seat does not start the anti-pinch function, it means that a misjudgment occurred when deciding whether to start the seat anti-pinch function. In this case, the seat status information and the working information of the seat motor at the time of the misjudgment can be recorded as abnormal data for subsequent analysis and learning optimization, and the intelligent algorithm model can be continuously trained and optimized based on user feedback.

[0051] In an exemplary embodiment of the present application, an intelligent algorithm model based on machine learning or deep learning can be developed to process and analyze the sensor data in the abnormal data. The model can learn the characteristic differences between the normal seat operation mode and the potential pinching event, automatically adjust the threshold, reduce the false alarm rate, and smooth the continuous abnormal data in a short period of time through sliding window filtering to avoid misjudgment caused by instantaneous interference. For the false anti-pinch caused by the seat consistency problem, self-learning correction can be performed, and the anti-pinch judgment parameters for specific travel ranges and working conditions can be differentiated and stored in the database. After multiple trainings, the false anti-pinch problem caused by the seat consistency problem can be effectively avoided.

[0052] In summary, combined Figure 2As shown, the anti-pinch control method for a vehicle seat can first obtain the speed change information of the seat motor, the current change information of the seat motor, the voltage change information of the seat motor, and the temperature change information of the seat motor during the process of the user adjusting the seat, and then determine whether the seat meets the pre-start condition of the seat anti-pinch function according to the speed change information of the seat motor, the current change information of the seat motor, the voltage change information of the seat motor, and the temperature change information of the seat motor. If it meets the pre-start condition, the pressure change information of the seat, the displacement change information of the seat motor, the seat occupancy information, and the obstacle information around the seat are obtained, and when it is determined that there is an obstacle in the anti-pinch direction of the seat, the seat is occupied, and / or the seat motor has a displacement change, and the pressure distribution point of the seat in the anti-pinch direction has a sudden change in pressure, it is determined that the state information of the seat matches the preset state information, and then the seat anti-pinch function is started. When it is determined that there is no obstacle in the anti-pinch direction of the seat and / or the seat is not occupied, and it is determined that there is no displacement change of the seat motor, and it is determined that there is no sudden change in pressure at the pressure distribution point of the seat in the anti-pinch direction, it is determined that the state information of the seat does not match the preset state information, and it is determined that the seat anti-pinch function has been misjudged, and then the seat anti-pinch function is not started.

[0053] Therefore, by combining the working information of the seat motor and the status information of the seat to determine whether to activate the seat anti-pinch function, false alarms can be reduced, unnecessary misoperations can be avoided, passenger comfort and safety can be improved, and ultimately the accuracy of seat anti-pinch judgment can be significantly improved.

[0054] In addition, when the working information of the seat motor meets the pre-start conditions of the seat anti-pinch function and it is determined that the seat status information does not match the preset status information, the seat status information and the working information of the seat motor at the time of this misjudgment can be recorded as abnormal data for subsequent analysis and learning optimization, and the intelligent algorithm model can be continuously trained and optimized based on user feedback, thereby improving the accuracy of the activation of the seat anti-pinch function.
