Description

Technical Field

[0001] The present application relates to the technical field of vehicle seat control, and in particular to a seat motor control method, device, equipment and storage medium under current limitation. Background Art

[0002] With the development of modern automobile technology, seat comfort has become an increasingly important aspect of vehicle design. The seat multi-motor control system can achieve precise adjustment of the seat position, including forward and backward movement, up and down adjustment, backrest and seat cushion tilt angle adjustment, and leg rest extension. The realization of these functions usually relies on multiple motors working together, each motor is responsible for different adjustment actions. However, the operation of the motor consumes a large current. If multiple motors are started at the same time, the current may exceed the safe load threshold of the wiring harness design, causing the wiring harness to overheat or even burn, which not only affects the normal use of the seat function, but also may cause hidden dangers to the safety performance of the vehicle.

[0003] To solve this problem, existing treatment methods include limiting the number of motors working at the same time and preventing current overload through hardware protection measures such as fuses and overcurrent relays. These hardware protection measures can automatically disconnect the circuit when the current exceeds the set threshold, thereby protecting the wiring harness from damage. In addition, some systems also use current monitoring technology to monitor the current status in real time. Once abnormal current is detected, the system will take measures to reduce current consumption, such as adjusting the running speed of the motor through software algorithms or temporarily stopping the operation of certain motors.

[0004] Although the above methods can protect the wiring harness from damage by overload current to a certain extent, they also have some limitations. First, the reaction time of the hardware protection measures may not be fast enough to cut off the circuit in time at the beginning of the current overload, which may cause the wiring harness to work in an overloaded state for a period of time, increasing the safety risk. Secondly, although the current monitoring technology can monitor the current status in real time, it is still a challenge to effectively allocate current resources to avoid overload when multiple motors are working at the same time. In addition, these methods usually require additional hardware support, which increases the complexity and cost of the system. Therefore, how to ensure the stable operation of multiple motors without changing the design of the seat power supply harness has become an urgent problem to be solved.

[0005] The above contents are only used to assist in understanding the technical solution of the present application and do not constitute an admission that the above contents are prior art. Summary of the invention

[0055] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0056] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0057] With the advancement of automobile technology, seat comfort has become the focus of vehicle design. Multi-motor control systems enable fine adjustment of seat positions, but the simultaneous operation of multiple motors may cause current overload, causing overheating or damage to the wiring harness, affecting seat function and vehicle safety. To this end, common measures include limiting the number of motors operating simultaneously, using hardware protection such as fuses, and current monitoring technology to prevent current overload. However, these methods have the problems of slow response, difficulty in current resource allocation, and increased system complexity and cost.

[0058] The main solution of the embodiment of the present application is: first, obtain the input signal priority, current input signal, motor movement priority and motor status information to lay the foundation for subsequent control decisions. Then, based on this information, determine the number of soft switch controls, automatically running motors and physical button control signals, and form an input signal sequence to understand the control requirements and motor status. Subsequently, the system comprehensively analyzes at least three key information such as motor information, current input signal, and the number of physical button control signals to determine the target input signal to ensure that user needs are met without exceeding the current load limit. Finally, the system controls the motor operation based on the motor movement priority and target input signal, accurately adjusts the seat position, avoids wiring harness damage caused by current overload, improves the accuracy and response speed of seat adjustment, while reducing energy consumption and extending motor life, and improving user experience.

[0059] It should be noted that the execution subject of the embodiment of the present application may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a motor control unit (MCU), a motor control system, etc. The motor control system is taken as an example to illustrate this embodiment and the following embodiments.

[0060] Based on this, the embodiment of the present application provides a seat multi-motor control method under current limiting conditions, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the seat multi-motor control method under current limiting conditions of the present application.

[0061] In this embodiment, the seat multi-motor control method under current limiting conditions includes steps S10 to S40:

[0062] Step S10, obtaining input signal priority, current input signal information, motor motion priority and motor information data;

[0063] It should be noted that the input signal priority refers to when multiple control signals are input at the same time, the system determines which signal should be processed first according to the preset rules. In this embodiment, the input signal priority is from high to low: physical button control input, vehicle computer adjustment soft switch input, seat automatic operation control input. This means that if there are multiple control signals input at the same time, the system will respond to the instructions of the physical button first, followed by the instructions of the vehicle computer adjustment soft switch, and finally the instructions of the seat automatic operation control system. The current input signal information refers to the specific content and related information of all control signals currently received by the system. This information may include input signals, signal strength, source, expected motor action, etc. In this embodiment, this information is used to determine which motors should be activated, as well as their movement direction and amplitude. For example, if the user requests the seat to move forward through a physical button, the system will recognize this signal and prepare to activate the motor responsible for forward and backward movement. Motor movement priority refers to the system determining which motors should perform actions first at the same time according to preset rules. In this embodiment, the motor movement priorities are from high to low: front and rear movement motor (A), up and down movement motor (B), backrest movement motor (C), seat cushion movement motor (D), and leg support movement motor (E). This means that if multiple motors need to work at the same time, the system will give priority to requests from the front and rear movement motors, then the up and down movement motors, and so on. Motor information data refers to detailed information related to each motor, including but not limited to the model, specifications, current status (such as whether it is running, running speed, position, etc.) of the motor and control parameters related thereto. In this embodiment, the motor information data is used by the system to accurately identify and adjust the actions of each motor when executing the control strategy, ensuring that they operate correctly according to the predetermined priority and order.

[0064] It can be understood that, firstly, the system monitors and obtains input signals from physical buttons, vehicle adjustment soft switches and seat automatic operation control systems in real time through built-in sensors and interfaces, which contain instructions for controlling seat motors. This is done to ensure that the system can receive all necessary control instructions and can adjust the position of the seat according to these instructions. Secondly, the system analyzes these input signals, determines their priority and current input signal information, such as signal strength, source and expected motor action, so that when multiple signals exist at the same time, they can be processed in order of importance to ensure that key control signals receive priority response. Then, the system refers to the preset motor movement priority to determine which motors should perform actions first at the same time, so that when multiple motors need to work at the same time, resources can be reasonably allocated to avoid current overload and ensure the accuracy and efficiency of seat adjustment. Finally, the system accurately controls the action of each motor based on motor information data, such as motor model, specification, current state and control parameters, so as to ensure that the motors operate correctly according to the predetermined priority and order, thereby achieving stable and safe multi-motor control. This series of steps together ensures that the system can effectively manage and control the operation of multiple motors without changing the existing seat power harness design.

[0065] Step S20, determining the number of soft switch control motors, automatic control motors, and physical button control input signals and the input signal sequence according to at least one of the current input signal information, the input signal priority, and the motor information data;

[0066] It should be noted that soft switch controlled motors refer to motors controlled by software switches in the vehicle system. These motors are usually responsible for certain auxiliary adjustment functions of the seats, such as seat heating or ventilation. Automatically controlled motors refer to motors that operate automatically according to preset programs or learned user habits, for example, motors controlled by seat position memory call instructions, voice control instructions, or automatic operation drive instructions for special scenarios. The number of input signals controlled by physical buttons refers to the number of control signals received from the physical buttons at the same time. The input signal sequence refers to a list of all input signals arranged in a certain order. This sequence reflects the priority and order of signal processing, ensuring that the system can respond to various control signals in a predetermined logical order.

[0067] It is understandable that first of all, the system will comprehensively consider the current input signal information, input signal priority, and motor information data, and use these data to determine which motors should be controlled by the soft switches in the vehicle system and which should run automatically according to the preset program, so as to ensure the accuracy and efficiency of the motor operation. Next, the system will calculate the number of control signals generated by the physical buttons, which will help to understand how much direct user input needs to be processed at present. Finally, the system will sort out an input signal sequence, which arranges all signals according to priority and predetermined processing order to ensure that the system can respond to each control signal in an orderly manner and achieve precise control. Such steps help the system to reasonably allocate resources and avoid current overload when multiple motors request to run at the same time, while ensuring the accuracy and response speed of seat adjustment.

[0068] As an example, the current input signal information includes the current input signal, and the motor information data includes the current running motor state information. The step of determining the number of soft switch control motors, automatic control motors, and physical button control input signals and the input signal sequence according to the current input signal information, the input signal priority and at least one of the motor information data includes: determining the soft switch control motor and the automatic control motor from multiple motors according to the current running motor state information; determining the number of physical button control input signals according to the current input signal; and prioritizing the current input signals according to the input signal priority to obtain an input signal sequence.

[0069] The current input signal refers to all the control commands currently received by the system. These commands may come from physical buttons, vehicle adjustment soft switches or seat automatic operation control systems, which indicate the specific actions that the seat motor needs to perform. The current running motor status information refers to the current working status of each motor in the system, including whether it is running, running speed, position and other information. This information is crucial for the system to decide which motors need to respond to new control signals.

[0070] First, the system analyzes the current running motor status information, which includes monitoring the operating status of each motor to determine which motors are currently active. Based on this information, the system can identify which motors are controlled by soft switches and which motors are running automatically. Next, the system counts the number of control signals generated by the physical buttons, which helps to understand how many direct user inputs need to be processed at present. Finally, the system sorts the current input signals according to the input signal priority, determines their processing order from high to low, and obtains the input signal sequence. This sequence ensures that the system can respond to each control signal in a predetermined logical order to achieve precise control. Such steps help the system to reasonably allocate resources and avoid current overload when multiple motors request to run at the same time, while ensuring the accuracy and response speed of seat adjustment.

[0071] Step S30, obtaining a target input signal according to at least three items of the motor information data, the current input signal information, the number of the physical button control input signals, the automatic control motor, the soft switch control motor, and the input signal sequence;

[0072] It should be noted that the target input signal refers to the signal that is finally selected to activate a specific motor among many input signals after comprehensive consideration of motor information data, current input signal information, the number of physical button control input signals, automatic motor control, soft switch motor control, and input signal sequence. For example, in this embodiment, at most two motors can be operated at the same time. The system will determine which signal should be executed first based on the above information to ensure that the current load limit is not exceeded while meeting the user's adjustment needs. This may involve selecting the most urgent or important control signal, or deciding which signal is most suitable for response based on preset priorities and motor status.

[0073] It is understood that first of all, the system will comprehensively consider six key information: motor information data, current input signal information, number of physical button control input signals, automatic control motor, soft switch control motor and input signal sequence. The motor information data provides detailed status of each motor, such as whether it is running; the current input signal information contains all instructions from different control sources; the number of physical button control input signals reflects the number of signals directly operated by the user; the automatic control motor and soft switch control motor respectively indicate which motors should respond according to the preset program or the vehicle soft switch; the input signal sequence prioritizes the signal processing. Then, the system will determine a target input signal based on at least three of these information, such as the importance and urgency of the current input signal, the preset program of the automatic control motor, and the priority in the input signal sequence. This target input signal is the most suitable signal for the current situation selected according to the current system status and user needs, under the premise of ensuring that the current load limit is not exceeded, to activate a specific motor for precise seat adjustment.

[0074] Step S40: Controlling the operation of the seat motor according to the motor movement priority and the target input signal.

[0075] It should be noted that the seat motor refers to the motor installed on the car seat for realizing the seat position adjustment function. These motors are usually responsible for driving various adjustment actions of the seat, such as forward and backward movement, up and down lifting, backrest tilt, seat cushion angle adjustment, and leg rest extension. In this embodiment, the seat motor is controlled according to the target input signal and the motor movement priority to ensure that when multiple motors request to run at the same time, resources can be reasonably allocated to avoid current overload, while ensuring the accuracy and response speed of seat adjustment.

[0076] It is understandable that first, the system will refer to the preset motor movement priority, which is an order set according to the importance of functions and user needs, such as the forward and backward movement motor (A), the up and down movement motor (B), the backrest adjustment motor (C), the seat cushion adjustment motor (D) and the leg support adjustment motor (E). Then, the system will activate a specific motor based on the target input signal, which is the most suitable signal for the current situation determined after comprehensive consideration of factors such as current input signal information, input signal priority, and motor information data. Finally, the system controls the operation of the seat motor based on these two information to ensure that the corresponding motors are accurately activated and controlled according to the priority order and user needs without exceeding the current load limit to achieve precise adjustment of the seat. This process involves the coordinated management of multiple motors to avoid current overload and ensure the accuracy and responsiveness of seat adjustment.

[0077] Please refer to Figure 2 , Figure 2The motor control principle diagram provided for the first embodiment of the multi-motor control method for a seat under current limiting conditions of the present application shows the core components of the motor control unit and the connection relationship between them, including the positive motor drive voltage (Motor+, voltage range 0~12V), the negative motor drive voltage (Motor-), the position sensor feedback input (Sensor5V+) and the motor control unit (MCU). As the center of the system, the motor control unit is responsible for receiving feedback signals from the position sensor and accurately controlling the movement of the motor based on these signals and input signals from the manual adjustment and automatic operation control systems. The positive and negative terminals of the motor drive voltage are directly connected to the motor to provide the necessary power for the motor. The position sensor provides information about the current position of the motor to the MCU through feedback input, which is crucial for achieving precise control.

[0078] As an example, the step of controlling the operation of the seat motor according to the motor movement priority and the target input signal includes: when the target input signal is a seat position memory call instruction, parsing the seat position memory call instruction to obtain a target memory position; determining a first seat motor adjustment parameter according to the target memory position; and controlling the seat motor to move to the target memory position according to the motor movement priority and the first seat motor adjustment parameter.

[0079] The seat position memory call instruction refers to the signal received by the system for calling the previously stored seat position setting. These instructions are usually generated by the user's previous operation or the system's automatic memory function. The target memory position refers to the specific seat position obtained after parsing the seat position memory call instruction. It is the preset position that the user wants the seat to automatically adjust to. The first seat motor adjustment parameter refers to the specific parameters calculated based on the target memory position and used to guide the seat motor to move to the target memory position. These parameters include the motor's rotation direction, speed and time, etc.

[0080] First, when the system receives the target input signal of the seat position memory call command, it will parse this command to determine the specific position that the user wants the seat to be adjusted to, which is called the target memory position. Then, the system will calculate the first seat motor adjustment parameters based on this target memory position. These parameters detail how the motor should operate to adjust the seat to the target memory position, including the motor's rotation direction, speed, etc. Finally, the system will control the seat motor according to the preset motor movement priority and these first seat motor adjustment parameters to ensure that the motor operates in the established order and parameters, so as to accurately adjust the seat to the position previously set by the user. This process ensures the accuracy and responsiveness of the seat adjustment while avoiding the risk of current overload.

[0081] As an example, the step of controlling the operation of the seat motor according to the motor motion priority and the target input signal includes: when the target input signal is a seat voice control instruction, parsing the seat voice control instruction to obtain a second seat motor adjustment parameter; adjusting the execution order of the parameters in the second seat motor adjustment parameter according to the motor motion priority to obtain the target seat motor adjustment parameter; and controlling the operation of the seat motor according to the target seat motor adjustment parameter.

[0082] Seat voice control instructions refer to instructions issued by the user to the system through voice commands to control the seat position. Such instructions allow users to adjust the seat through verbal commands for convenient operation. Second seat motor adjustment parameters refer to parameters calculated by the system based on the parsed seat voice control instructions to guide the seat motor to move to the target position. These parameters detail how the motor should operate, including the direction and speed of the motor's rotation, to ensure that the seat can be correctly adjusted according to the voice instructions. Target seat motor adjustment parameters refer to parameters obtained by the system after adjusting the execution order of parameters in the second seat motor adjustment parameters according to the motor movement priority. These parameters ensure that the motor is executed in priority order and with the correct parameters, so as to accurately control the operation of the seat motor to reach the position specified by the user through voice commands.

[0083] First, when the system receives the target input signal of the user's voice control command for the seat, it parses the command to determine the user's desired seat position change, thereby obtaining the second seat motor adjustment parameters, which detail how the motor should operate in response to the voice command. Next, the system adjusts the execution order of the parameters in these parameters according to the preset motor motion priority to ensure that the motor operates in the correct order and parameters to obtain the target seat motor adjustment parameters, which can avoid current overload or adjustment errors caused by improper priority. Finally, the system controls the seat motor according to these target seat motor adjustment parameters to ensure that the motor operates in the established order and parameters, and accurately adjusts the seat to the position specified by the user through voice commands. This process not only improves the convenience of operation, but also ensures the accuracy of seat adjustment and the response speed of the system.

[0084] This embodiment provides a seat multi-motor control method under current limiting conditions, obtaining input signal priority, current input signal information, motor motion priority and motor information data; determining the number of soft switch control motors, automatic control motors, physical button control input signals and input signal sequence according to at least one of the current input signal information, the input signal priority and the motor information data; obtaining the target input signal according to at least three of the motor information data, the current input signal information, the number of physical button control input signals, the automatic control motor, the soft switch control motor and the input signal sequence; controlling the seat motor operation according to the motor motion priority and the target input signal. First, the system fully grasps the current control environment and motor status by obtaining the input signal priority, the current input signal information, the motor motion priority and the motor information data. This information provides the basis for the system to make decisions and ensure that the subsequent steps can be accurately executed. Then, the system determines which motors should be controlled by soft switches, which should be automatically operated, and the number of control signals generated by the physical button according to the current input signal information, the input signal priority and at least one of the motor information data, and constructs the input signal sequence. This step helps the system understand the current control requirements and the operating status of the motor, and provides a basis for the reasonable allocation of resources. Then, the system determines the target input signal based on at least three key information, such as motor information data, current input signal information, and the number of physical button control input signals. This target input signal is selected after comprehensive consideration of all relevant factors and is used to activate the signal of a specific motor to ensure that the user's adjustment needs are met without exceeding the current load limit. Finally, the system controls the operation of the seat motor based on the motor movement priority and the target input signal. This step ensures that the motor operates in the established order and parameters to accurately adjust the seat to the user's desired position. This series of steps enables the system to ensure the stable operation of multiple motors without changing the design of the seat power supply harness, avoiding overheating or damage to the harness due to current overload, while improving the accuracy and response speed of seat adjustment and enhancing the user experience. In addition, by intelligently managing and controlling the operation of the motor, the system can effectively reduce energy consumption and extend the service life of the motor, providing users with a more reliable and economical seat adjustment solution.

[0085] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can refer to the above introduction, and will not be repeated later. Figure 3 , Figure 3This is a flow chart of the second embodiment of the seat multi-motor control method under current limiting conditions of the present application, wherein the motor information data includes the current number of running motors and the running motor threshold, the current input signal information includes the current number of input signals, and step S30 of the seat multi-motor control method under current limiting conditions includes steps S31-S32:

[0086] Step S31, controlling the automatic control motor and the soft switch control motor according to at least three items of the current number of running motors, the running motor threshold, the current number of input signals, and the number of physical button control input signals, and reacquiring the current number of running motors after the control is completed;

[0087] It should be noted that the current number of running motors refers to the total number of motors that are working at the current moment. This number is an important parameter for the system because it is directly related to whether more motors can be started to avoid exceeding the load threshold of the wiring harness design. The running motor threshold refers to the maximum number of motors allowed to run simultaneously by the system. This value is set based on the load capacity of the wiring harness design to ensure that the system operates within a safe current range. The current number of input signals refers to the total number of all control signals currently received by the system, including signals from physical buttons, vehicle adjustment soft switches, and seat automatic operation control systems. This number reflects the current user's demand for seat adjustment.

[0088] It is understandable that first, the system will refer to the motor information data, which includes the number of motors currently running and the maximum number of motors allowed by the system (running motor threshold), as well as the current input signal information, which covers the number of all received control signals. Next, the system will decide how to control the automatic control motor and the soft switch control motor based on at least three of these key data, such as the current number of running motors, the running motor threshold, and the current number of input signals. For example, if the current number of running motors plus the current number of input signals exceeds the running motor threshold, the system may suspend the operation of some motors to ensure that the current load limit is not exceeded. In addition, if the number of physical button control input signals indicates direct user operation, the system may give priority to these signals. After the control is completed, the system will re-acquire the current number of running motors to update the system status and provide the latest information for the next round of control decisions. This approach ensures that the system can flexibly respond to user needs while keeping the current within a safe range, thereby optimizing the seat adjustment process and improving the user experience.

[0089] As an example, the automatic control motor and the soft switch control motor are controlled according to at least three of the current number of running motors, the running motor threshold, the current number of input signals and the number of physical button control input signals, and the step of reacquiring the current number of running motors after the control is completed includes: when the current number of running motors is equal to the running motor threshold and the current number of input signals is greater than the preset signal number, stopping the operation of the automatic control motor and reacquiring the current number of running motors; when the current number of running motors is equal to the running motor threshold and the number of physical button control input signals is greater than the preset signal number, stopping the operation of the soft switch control motor and reacquiring the current number of running motors.

[0090] The preset signal quantity refers to a threshold value set by the system, which is used to determine whether there are enough input signals to trigger the stop of the automatic control motor or the soft switch control motor. In this embodiment, the preset signal quantity is 0, which means that when the current number of running motors is equal to the running motor threshold and there are other signal inputs, the system will stop the automatic control motor; when the current number of running motors is equal to the running motor threshold and there is a physical button signal input, the system will further stop the soft opening control motor. For example, if the system allows two motors to run at the same time (the running motor threshold is 2), and there are currently two motors running, at this time, if the system detects any new input signal, it will decide whether to stop the automatic control motor or the soft switch control motor according to the number of input signals. If the number of new input signals is greater than 0, it indicates that there is a new control demand. The system may stop a motor in response to the new control signal, and re-acquire the current number of running motors to update the system status.

[0091] First, the system will comprehensively evaluate whether the current number of running motors has reached the set running motor threshold, and whether the current number of input signals and the number of physical button control input signals exceed the preset signal number threshold. In this embodiment, the preset number of signals is 0, so the system is very sensitive to input signals. If the current number of running motors has reached the upper limit and there are other signal inputs, the system will determine that it is necessary to stop the automatic control of the motor to prevent current overload, and then the system will re-acquire the current number of running motors to update the status. Similarly, if the current number of running motors has reached the upper limit and the number of physical button control input signals is greater than 0, indicating that there is a direct physical operation requirement, the system will stop the soft switch control motor to ensure that the current is within a safe range, and re-acquire the current number of running motors to reflect the latest operating status. Such control logic ensures that the system can flexibly respond to the user's control needs without exceeding the current load, while maintaining effective management of the current.

[0092] Please refer to Figure 4 , Figure 4 The schematic diagram of the automatic control operation strategy provided for the second embodiment of the seat multi-motor control method under the current limiting condition of the present application shows the process of the seat multi-motor automatic control operation strategy. Starting from judging whether the motor is in a stationary state, the system first checks whether there is a new automatic operation control instruction. If so, the system will evaluate whether all the current motors are in a stationary state. If not, all motors will be stopped to avoid conflicts and potential safety risks. If all motors are in a stationary state, the system will proceed to the next step and execute the two motors with the highest priority among the motors to be run according to the preset priority order. If the number of motors currently running is less than two (two in this embodiment), the system will allow the highest priority motor to be started. This process continues until all motors to be run have been executed. This strategy ensures the orderliness and safety of motor operation, and at the same time optimizes the order of motor response through the priority mechanism, thereby improving the efficiency of the system and user satisfaction.

[0093] Please refer to Figure 5 , Figure 5 A schematic diagram of the physical button control operation strategy provided in the second embodiment of the seat multi-motor control method under the current limiting condition of the present application shows the process of the physical button control operation strategy in the seat motor control system. Starting from receiving the input signal of the physical switch or the vehicle switch, the system first checks whether the current number of motors running is less than 2 (the maximum number of simultaneous operations in this embodiment is 2). If so, the system will further check whether all motors are already in motion. If the number of motors running is less than 1, the system will compare the motors that are not in motion with a higher priority and execute the motor with the highest priority. If the number of motors running is less than 2 and the number of switch input signals is greater than 1, the system will stop the operation of all motors and set all switch input signals to 0 to ensure that the system can re-evaluate the control signal and prepare to accept new instructions. This process continues until all switch input signals are processed or until the system determines that there is no more motion demand. This strategy ensures that the physical button control input can be responded to in a timely manner, and when multiple motors request to run at the same time, the current load can be effectively managed to prevent overload, while maintaining the flexibility and response speed of the system.

[0094] Please refer to Figure 6 , Figure 6The schematic diagram of the operation strategy when physical button control and automatic control coexist on the same motor provided in the second embodiment of the seat multi-motor control method under the current limiting condition of the present application shows the operation strategy when physical button control instructions and automatic control instructions coexist in the seat motor control system. The process starts by checking whether there is a manual adjustment instruction. If there is a manual adjustment instruction, the system will execute the corresponding motor action according to the manual control strategy to ensure that the user's direct operation is given priority response. If there is no manual adjustment instruction, the system will process the new drive instruction according to the automatic operation control strategy. In both cases, the system will execute the corresponding motor action until all motors complete their action tasks, and then the process ends. This strategy ensures that both the operation performed directly by the user through the physical button and the adjustment performed automatically by the system according to the preset program can be properly processed, and the system can flexibly switch between the two control modes to adapt to different usage scenarios and user needs.

[0095] Step S32, obtaining a target input signal according to the current number of running motors, the running motor threshold and the input signal sequence.

[0096] It should be noted that first, the system will review the current number of running motors, that is, the total number of motors currently working, and the running motor threshold, that is, the maximum number of motors allowed to run simultaneously by the system. At the same time, the system will refer to the input signal sequence, which is a list of signals sorted by priority, which determines the order in which the signals are processed. The system will analyze this information to determine which input signals are critical, that is, the target input signals, which will be used to control the next action of the motor. If the current number of running motors is close to or equal to the running motor threshold, the system may select a higher priority signal as the target input signal to ensure that the operation of the motor is effectively controlled without exceeding the current load. This process involves careful consideration of the priority of the signal and the current state of the motor to ensure that the system can make the most appropriate decision to optimize the operating efficiency of the motor and the use of current.

[0097] It is understood that first, the system will evaluate whether the current number of running motors has reached the set running motor threshold, which is the maximum number of motors allowed to run simultaneously by the system, in order to ensure that the load limit of the wiring harness design is not exceeded. Secondly, the system will check the input signal sequence, which is a list of signals sorted according to preset priorities, in order to determine which control signals are most urgently needed to respond. Then, the system will determine the target input signal based on the current number of running motors and the priority in the input signal sequence, in order to select the most appropriate signal to control the next action of the motor without exceeding the current load. Finally, the system will control the seat motor according to the target input signal, in order to accurately meet the user's adjustment needs while maintaining the stability and safe operation of the system. Through this series of steps, the system can effectively respond to the user's control needs while ensuring that the current is not overloaded, and improve the accuracy and response speed of seat adjustment.

[0098] As an example, the step of obtaining the target input signal according to the current number of running motors, the running motor threshold and the input signal sequence includes: when the current number of running motors is less than the running motor threshold, calculating the difference between the current number of running motors and the running motor threshold to obtain the target input signal number; determining the starting point and the ending point of the target input signal in the input signal sequence according to the target input signal number; and extracting the input signal between the starting point and the ending point from the input signal sequence as the target input signal.

[0099] The target number of input signals refers to the number of motor control signals that can be added when the current number of running motors has not reached the running motor threshold, calculated by the system based on the difference between the current number of running motors and the running motor threshold. This number reflects how many additional control signals the system can handle without exceeding the current load. The starting point and the ending point refer to the range in the input signal sequence that is determined based on the target number of input signals and is used to extract the target input signal. The starting point is the position of the first signal in this range, and the ending point is the position of the last signal. The system will extract signals from the input signal sequence from the starting point to the ending point as the target input signal to control the next action of the motor.

[0100] First, the system checks whether the current number of running motors has not reached the set running motor threshold. This step is to determine whether the system is capable of handling more control signals. If the current number of running motors is less than the running motor threshold, the system calculates the difference between the two values. This difference represents how many new control signals the system can still receive, that is, the target number of input signals. Next, the system determines the starting and ending points in the input signal sequence based on this number. These two points define which part of the signal from the sequence will be selected as the target input signal. Finally, the system extracts the signals from the starting point to the ending point from the input signal sequence. These signals are considered to be the most urgent or important and will be used to control the next action of the motor. This method ensures that the system can effectively manage motor control signals while keeping the current load within a safe range, improving the system's response speed and regulation accuracy.

[0101] This embodiment controls the automatic control motor and the soft switch control motor according to at least three of the current number of running motors, the running motor threshold, the current number of input signals, and the number of physical button control input signals, and reacquires the current number of running motors after the control is completed; and obtains the target input signal according to the current number of running motors, the running motor threshold, and the input signal sequence. First, the system comprehensively considers the current number of running motors, the running motor threshold, the current number of input signals, and the number of physical button control input signals, which provide a comprehensive view of the current system load and user operation requirements. If the current number of running motors has reached or is close to the running motor threshold, the system will carefully control the automatic control motor and the soft switch control motor to avoid exceeding the current load limit. For example, if the current number of running motors is less than the running motor threshold, the system may activate more motors to respond to user requests. Then, after the control is completed, the system will reacquire the current number of running motors to update the system status and ensure that all control actions are based on the latest information. Next, the system will determine the target input signal based on the current number of running motors, the running motor threshold, and the input signal sequence. This step involves extracting the most relevant signals from the input signal sequence, which will be used to accurately control the next action of the motor. In this way, the system can flexibly respond to the user's control needs while ensuring that the current load remains within a safe range. The beneficial effect is that this method improves the system's response speed and regulation accuracy, while avoiding potential damage caused by current overload, enhancing the user experience and system reliability.
