The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. Additionally, examples of various specific processes and materials are provided in this invention; however, those skilled in the art will recognize the applicability of other processes and / or the use of other materials.

[0019] Please refer to Figure 1 and Figure 2 The seat table 20 is rotatably connected to the seat back 10 via a linkage mechanism 30. During the process of the seat table 20 being controlled to retract from the open state, the travel of the front part of the seat table 20 gradually decreases. The seat table anti-pinch control system provided by the present invention is used to intelligently control the retraction of the seat table 20, accurately prevent pinching, and eliminate safety hazards.

[0020] Please refer to this as well. Figures 1 to 3 The anti-pinch control system for the seat and table includes: The seat table 20 is rotatably mounted on the seat back 10; The drive module 40 is connected to the seat table 20 in a driving manner; The sensor module 50 is disposed on or adjacent to the seat table 20, and includes a sensing and identification sensor 51 and a contact identification sensor 52. The sensing and identification sensor 51 is used to sense and identify the presence of an obstacle in the seat table 20 during its movement and generate a first abnormality information. The contact identification sensor 52 is used to identify the contact of the seat table 20 with an obstacle during its movement and generate a second abnormality information. The electronic control unit (ECU) is used to send drive control signals to control the drive module 40 to rotate the seat table 20, receive rotation stroke information of the drive module 40, and generate an abnormal state drive control signal according to the first abnormal signal or the second abnormal signal and send it to the drive module 40.

[0021] The sensor module 51 identifies obstacles in the rotational travel of the seat tray 20, such as objects along its path, most likely the user's hand. The contact sensor 52 identifies when the seat tray 20 directly contacts an obstacle and is blocked during its rotation. By identifying these two types of obstacles during the seat tray 20's operation and responding accordingly, the sensor module 50 can perform different anomaly detection and processing. This diversified processing improves the accuracy and intelligence of anomaly detection.

[0022] The electronic control unit (ECU) consists of a microcontroller (MCU), memory (ROM, RAM), input / output interface (I / O), analog-to-digital converter (A / D), and large-scale integrated circuits for shaping and driving. It is mainly responsible for receiving data, processing the collected raw data, and controlling the various modules of the seat and table anti-pinch control system based on the processed data.

[0023] Furthermore, the sensing and identification sensor 51 includes at least one of a capacitance detector, an infrared sensor, and an ultrasonic sensor.

[0024] Specifically, the capacitance detector periodically measures the capacitance value of the circuit connected to the electrodes. An abnormal change in the capacitance value indicates the presence of an obstacle. For example, the capacitance sensor is installed inside the seat table 20, and its wires are placed inside the linkage mechanism 30. The linkage mechanism includes four metal links, with two links on each side forming a rotating mechanism on one side. The four metal links act as conductors to detect the approach of an object. When a change in capacitance value is detected, different anti-pinch strategies are adopted according to different capacitance value change thresholds. The anti-pinch mechanism is triggered when the motor moves within a certain range of the anti-pinch zone. This anti-pinch zone is triggered when the four links move to a distance greater than 10.1mm above the decorative strip. It primarily detects whether the capacitance change value is close to the capacitance change value caused by the approach of a human body. When both of these conditions are met, the capacitance anti-pinch mechanism is triggered, the motor stops running, and the user is alerted that there is a foreign object at the four links.

[0025] An infrared sensor is mounted on the seat / table 20. It measures distance or detects objects in the space during the seat / table 20's movement by emitting infrared light and detecting the reflected infrared light. During normal operation, the infrared sensor feedback changes systematically; for example, when the seat / table 20 rotates back, the infrared distance measurement gradually decreases. A sudden drop in distance is detected, indicating the presence of an obstacle. An ultrasonic sensor operates on a similar principle to the infrared sensor. Mounted on the seat / table 20, it measures distance by the time difference between the emitted pulse and the received echo, identifying obstacles based on the measured distance. In this embodiment, the sensing and identification sensor 51 can be one, two, or three of the aforementioned sensors; adding different types of sensors improves the accuracy of identification.

[0026] Furthermore, the contact recognition sensor 52 includes at least one of a current sensor and a Hall sensor.

[0027] Specifically, the current sensor or the Hall sensor is used to detect the driving state of the drive module 40, and is correspondingly set in the drive module 40, such as the current of the motor or the rotation information of the motor. When the drive module 40 is in normal operating condition, the operating current of the motor in the seat / table 20 remains stable. When the seat / table 20 is blocked by an obstacle, the rotation of the motor is correspondingly blocked, and its current changes abruptly, thus indicating contact with an obstacle. The recognition principle of the Hall sensor is similar to that of current detection recognition; it detects the rotation angle of the motor. When an abnormal rotation angle is detected, it can be determined that contact with an obstacle has occurred. In this embodiment, one or two contact recognition sensors 52 can be used to improve recognition accuracy.

[0028] Furthermore, the electronic control unit (ECU) is specifically used to send drive control signals to control the drive module 40 to rotate the seat table 20, receive rotation stroke information of the drive module 40, and generate a stop drive control signal according to the first abnormal signal and send it to the drive module 40; and / or generate a reverse drive control signal according to the second abnormal signal and send it to the drive module 40.

[0029] In this embodiment, abnormal states are distinguished between sensor-identified obstacles and contact-identified obstacles. For sensor-identified obstacles, the seat table 20 is controlled to stop rotating, and for contact-identified obstacles, the seat table 20 is controlled to rotate in the opposite direction. This achieves diversified anti-pinch control and improves the accuracy and intelligence of the control.

[0030] Furthermore, the electronic control unit (ECU) is also used to generate a sensor operating signal based on the rotational stroke information and send it to the sensing and identification sensor 51. In this embodiment, by determining the stroke state of the seat table 20 and performing differentiated detection and identification control, the intelligence of the anti-pinch control is further improved.

[0031] Furthermore, the electronic control unit (ECU) is specifically used to determine, based on the rotation stroke information, that the seat table 20 is in a rotation retraction process, generate a sensor activation signal, and send it to the sensing and identification sensor 51; or, based on the rotation stroke information, determine that the seat table 20 is in a non-rotation retraction process, generate a sensor sleep signal, and send it to the sensing and identification sensor 51.

[0032] Furthermore, the electronic control unit (ECU) is specifically used to send drive control signals to control the drive module 40 to rotate the seat table 20, receive rotation stroke information of the drive module 40, and generate an abnormal state drive control signal based on the motion stroke information and the first abnormal signal or the second abnormal signal and send it to the drive module 40.

[0033] In this embodiment, anti-pinch control is implemented for different rotation stroke positions of the seat table 20, further improving the intelligence.

[0034] Furthermore, the electronic control unit (ECU) is specifically used to send drive control signals to control the drive module 40 to rotate the seat table 20, receive the rotation stroke information of the drive module 40, and determine whether the motion stroke information meets the preset stroke range based on the first abnormal signal or the second abnormal signal, generate an abnormal state drive control signal based on the determination result and send it to the drive module 40.

[0035] Furthermore, the electronic control unit (ECU) is specifically used to send drive control signals to control the drive module 40 to rotate the seat table 20, receive rotation stroke information of the drive module 40, and generate a first drive control signal based on a first abnormal signal or a second abnormal signal to determine if the motion stroke information meets a preset stroke range, or generate a second drive control signal based on a determination if the motion stroke information does not meet a preset stroke range, and control the drive module 40 based on the first drive control signal or the second drive control signal.

[0036] Wherein, the preset travel range is the travel range in which the remaining folding travel is greater than a preset value, the first drive control signal is a stop drive control signal, and the second drive control signal is a reverse drive control signal.

[0037] Furthermore, the seat and table anti-pinch control system also includes an audible and visual alarm module 60, which is used to receive an alarm control signal generated by the electronic control unit (ECU) based on the abnormal state information, and to drive the audible and visual alarm based on the alarm control signal.

[0038] The anti-pinch control system for the seat and table also includes an interaction module 70, which is used to receive user operation commands and send the operation commands to the electronic control unit (ECU).

[0039] The seat and table anti-pinch control system also includes a communication module 80, which is used to communicate with the electronic control unit (ECU) and external devices, such as vehicle control equipment and cloud networks.

[0040] The anti-pinch control system for the seat and table also includes a self-test module (not shown in the figure), which is used to control the sensor module and the electronic control unit (ECU) to perform initialization and self-test processes respectively according to at least one of the preset cycle, power-on signal, and external command.

[0041] To process abnormal signals in real time and assess the necessary anti-pinch actions, the seat and table anti-pinch control system creates multiple tasks to achieve this, and its general control flow is as follows: Figure 4 As shown. The specific process includes: After the chair and table are powered on, the system creates an event group to store the flags for each task's feedback. After each device is initialized, the system creates various tasks: Self-test task: This task mainly avoids excessive deviation between the data of the sensor module and the actual situation. The self-test task restores modules with large deviations to normal.

[0042] Input task: This task mainly receives information from the sensor module, button module, and external communication module, and puts it into a queue for unified management of the input data.

[0043] Anomaly Handling Task: This task mainly handles abnormal signals from the input task, and promptly assesses the current state of the seat / table before taking corresponding equipment actions to ensure the safety of the equipment and the user.

[0044] After creating different tasks, their priorities are further set, and the scheduler is started to allow the tasks to begin running.

[0045] Specifically, the self-test process of the seat and table anti-pinch control system is as follows: Figure 5 As shown, the self-test task is one of the key tasks executed during system startup to ensure that all sensors and critical components are functioning correctly. The following is the logical flow of the self-test task: After the system starts up, the scheduler triggers a self-test task, first initializing each module, and then performing the self-test program for each module.

[0046] Perform a self-test on the ultrasonic sensor by sending a test signal to the ultrasonic sensor to check whether the sensor responds correctly to the test signal and to verify whether the transmission and reception functions are normal.

[0047] Perform a self-test on the infrared sensor by sending a test signal to the infrared sensor to check whether the sensor responds correctly to the test signal and to verify whether the transmission and reception functions are normal.

[0048] Perform a self-test on the capacitance sensor by applying a test voltage. Measure the change in capacitance of the sensor to verify that it can correctly measure capacitance changes.

[0049] When performing a Hall sensor self-test, the static test determines whether the value is stable, and when performing a dynamic test, it checks whether the Hall number meets the corresponding stroke Hall number.

[0050] Perform a current self-test to check whether the sensor output is zero or within the expected range when no current flows through it, and whether the normal operating current is within the expected range to determine whether it is normal.

[0051] Perform an ECU self-test to check whether the ECU's microcontroller (MCU), memory (ROM, RAM), input / output interfaces (I / O) are working properly.

[0052] Finally, the test results of all modules will be placed in the self-test event group after the corresponding self-test logic is completed. The system will check whether the self-test logic flags of each module in the self-test event group are normal. Finally, the system will make a startup decision. If there are no critical errors, the system will run normally, which means the self-test is successful. If there are critical errors, such as ECU, current, or Hall abnormalities, the system will stop running and enter safe mode, waiting for user confirmation.

[0053] Specifically, the input task flow of the seat and table anti-pinch control system is as follows: Figure 6 As shown, when the seat tray is powered on, the input task is initiated by the scheduler. The system collects data from multiple sensor modules, including human infrared sensors, current sensors, ultrasonic sensors, and capacitive sensors, to monitor the status of the seat tray and environmental conditions. The system can also receive user input from the button module, allowing the driver or passenger to directly control the functions of the seat tray.

[0054] The system synchronizes data from external communication modules, including communication data with other vehicle systems or external devices (such as smartphones), allowing the seat trays to communicate with the external environment.

[0055] Next, all received data is placed into a queue for management. The data is processed in the queue, filtered, integrated, or transformed as needed, and then passed to the ECU. For example, adding a corresponding timestamp to each input data point allows for tracing the source of any abnormal data during this process.

[0056] This task ensures the order and integrity of the data, as well as the efficiency of the processing.

[0057] Specifically, the abnormal handling task flow of the seat and table anti-pinch control system is as follows: Figure 7 As shown, after the exception handling task starts, the system will check the self-test task results. If there is an abnormal device, the exception will be recorded and the data of the device will be ignored. If there is a critical error, such as an abnormality of the electronic control unit (ECU), current, or Hall effect sensor, the system will stop running.

[0058] The system then detects the current motor travel and determines the current seat table travel using Hall effect sensors and current readings. When the seat table is in the retracted position, the non-contact anti-pinch event works normally. To prevent accidental activation due to items placed on the seat table, the non-contact anti-pinch event does not work in other states.

[0059] For inductive anti-pinch events such as those from human infrared sensor data, capacitive sensor data, and ultrasonic sensor data, if any of the following occurs, it is considered a possible anti-pinch situation: human infrared sensor data exceeds the set threshold, capacitive sensor voltage is too high, or ultrasonic sensor pulse reception time is too short. The motor will stop running, maintain the current posture, and wait for user confirmation. The user can notify the seat / table to confirm the anti-pinch status via buttons or external communication.

[0060] For contact-type anti-pinch events, the system can determine the current travel of the seat / table by measuring the current and Hall effect values. When the system detects a large current and a small Hall effect change at different travel distances, it considers this a possible anti-pinch situation. The motor reverses to attempt to release the clamping state and issues an audible and visual alarm to remind the user. The user can confirm the anti-pinch status by pressing a button or communicating with the seat / table via external communication.

[0061] Once the sensor data returns to normal or the motor completes its reverse rotation, record the anomaly handling results. Determine whether to continue the retraction action or stop based on the system status.

[0062] The seat and table anti-pinch control system provided by the present invention uses a combination of inductive recognition sensor 51 and contact recognition sensor 52 to identify different types of obstacles, generate abnormal state information according to different abnormal obstacle types, and then perform corresponding abnormal state drive control. Under different abnormal states, the seat and table 20 is controlled to stop moving or move in the opposite direction, so as to achieve diversified anti-pinch control and achieve precise anti-pinch effect. Moreover, the seat and table anti-pinch control system has a simple structure and is easy to be industrialized on a large scale.
