[0064] The control method, device, electric seat, vehicle, and electronic equipment of the present application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0065] The control method for the electric seat can be applied to a controller, which can output control signals to each motor of the electric seat, so that each motor drives the electric seat to move based on the corresponding control signals.

[0066] The electric seat control method provided in this application embodiment can be executed by an electronic device or a functional module or entity in an electronic device that can implement the electric seat control method. The electronic devices mentioned in this application embodiment include, but are not limited to, mobile phones, tablets, computers, wearable devices and controllers. The electric seat control method provided in this application embodiment will be described below using an electronic device as the execution subject.

[0067] like Figure 1 As shown in the figure, this application embodiment provides a control method for an electric seat, which includes steps 110, 120 and 130.

[0068] Step 110: Obtain the settings information input by the user; the settings information shall include at least the target working mode selected from multiple working modes of the electric seat.

[0069] An electric seat is a seating system that uses an electric motor to drive and adjust the seat position. It makes seat adjustments more convenient, typically including adjusting the seat's fore-and-aft position, tilt angle, seat height, backrest angle, and headrest height.

[0070] This electric seat can be installed on various vehicles such as cars, ships, and aircraft.

[0071] The electric seat is equipped with a controller that can control the rotation of each motor of the electric seat. Specifically, the controller can be a dedicated microcontroller or the vehicle's main controller, etc., without limitation.

[0072] The execution entity of this application embodiment supports interaction with the user. The setting information is for the user to adjust various parameters and positions of the electric seat according to personal needs in order to achieve optimal comfort and support.

[0073] The settings information can be entered in the following ways:

[0074] Firstly, the settings can include touch operations, including but not limited to click, swipe, and press operations.

[0075] In this embodiment, receiving user input settings information can be receiving touch operations from the user on the display area of ​​the seat's screen; it can also be receiving touch operations from the user on the display area of ​​a mobile phone or other terminal; or it can be receiving touch operations from the user on the display area of ​​the vehicle's screen, etc.

[0076] Secondly, the settings can be entered using physical buttons.

[0077] In this embodiment, the electric seat is equipped with physical buttons on its body to receive setting information input by the user. This can be receiving the user's operation of pressing the corresponding physical button; the setting information can also be a combination operation of pressing multiple physical buttons simultaneously.

[0078] Thirdly, the settings can also include voice input.

[0079] In this embodiment, the electric seat can trigger a settings information display interface when it receives a voice prompt such as "Set Trojan Mode".

[0080] Of course, in other embodiments, the setting information may also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs, and this application embodiment does not limit it.

[0081] The electric seat in this application embodiment supports a cradle function, which includes multiple working modes, including a single working mode and multiple working modes.

[0082] The single operating mode indicates a single direction and is designed to allow the power seat to move back and forth in a single direction.

[0083] Single-working modes include Pingyao mode, Trojan mode, and Swing mode.

[0084] In Pingyao mode, the electric seat moves back and forth in the front and back direction.

[0085] In Trojan mode, the electric seat moves back and forth in the up and down direction.

[0086] In rocking mode, the electric seat moves back and forth in the left and right directions.

[0087] Multiple operating modes indicate multiple directions, designed to enable the power seat to perform compound movements in multiple directions.

[0088] Multiple working modes can allow the electric seat to move back and forth in at least two of the following directions: forward and backward, up and down, and left and right.

[0089] For example, the multiple working modes can be specifically a swing mode, in which the electric seat performs compound movements in the forward and backward direction and the up and down angle direction.

[0090] The setting information in this application embodiment includes at least a target working mode selected from multiple working modes of the electric seat. The working mode can be any of the single working modes or any of the multiple working modes mentioned above, and there is no limitation on this.

[0091] Step 120: When the target working mode is multiple working modes, the multiple working modes indicate multiple target directions. Based on the pre-created mapping relationship between directions and motors, determine multiple first target motors corresponding to multiple target directions from multiple first motors.

[0092] The electric seat includes multiple first motors for driving the electric seat to move back and forth in different directions. For example, the first motor in the forward and backward direction is a slide rail motor, the first motor in the up and down direction is a lever motor, and the first motor in the left and right direction is a lever motor, etc.

[0093] The direction here can be either the sliding direction or the swinging direction.

[0094] Specifically, for example, a sliding track is set at the bottom of the electric seat. The sliding track motor can drive the electric seat to slide back and forth along the track, such as first sliding forward and then sliding backward. The direction at this time is the sliding direction.

[0095] In the up-down direction, the corresponding lever motor can drive the electric seat to rock up and down; the direction of this rocking motion is the direction of the rocking motion.

[0096] In terms of left and right directions, the corresponding lever motor can drive the electric seat to sway left and right, and the direction of this swaying is the direction of the sway.

[0097] As described in the foregoing embodiments, the electric seat supports multiple working modes. When the target working mode is multiple working modes, the multiple directions indicated by the multiple working modes can be determined. The multiple directions can be at least two of the following: forward and backward direction (also known as forward and backward sliding direction), left and right direction (also known as left and right rocking direction), and up and down direction (also known as up and down rocking direction).

[0098] In this embodiment, a corresponding first motor is provided in each direction, and each first motor can drive the electric seat to move back and forth in the corresponding direction.

[0099] For example, the first motor in the forward and backward direction is a horizontal slide rail motor, the first motor in the up and down direction can be a height-adjustable lever motor, and the first motor in the left and right direction can be a servo motor for adjusting the left and right sway of the electric seat.

[0100] In this application embodiment, a mapping relationship between direction and motor is pre-created. Specifically, it can be a mapping relationship between the reverse direction identifier and the motor identifier. Based on this mapping relationship, multiple first target motors corresponding to multiple working modes can be found from multiple first motors.

[0101] Step 130: Send first control signals to the multiple first target motors respectively, so that each first target motor drives the electric seat to perform back-and-forth compound motion along multiple target directions based on the corresponding first control signal.

[0102] After identifying multiple first target motors, the controller can send a first control signal to each first target motor. The first control signal is used to change at least a portion of the input voltage, input current, and duty cycle of the first target motor. Each first target motor can drive the electric seat to move back and forth along multiple target directions based on the corresponding first control signal, presenting a compound motion effect.

[0103] The electric seat control method provided in this application embodiment obtains user-inputted setting information, which includes at least a target working mode selected from multiple working modes of the electric seat, thereby enabling users to personalize the selection of the target working mode of the electric seat and meeting personalized needs.

[0104] The electric seat includes multiple first motors for driving the electric seat to move back and forth in different directions. When the target working mode is multiple working modes, the multiple working modes indicate multiple target directions. According to the pre-created mapping relationship between directions and motors, multiple first target motors corresponding to multiple target directions are determined from the multiple first motors. First control signals are sent to the multiple first target motors respectively, so that each first target motor drives the electric seat to perform back-and-forth compound movements along multiple target directions based on the corresponding first control signals. This can solve the problem that the electric seats provided by related technologies only support back-and-forth swinging at a single angle position, resulting in a relatively monotonous user experience. The electric seat of this application supports compound movements in multiple dimensions, which can effectively improve the passenger's riding experience.

[0105] In some embodiments, the setting information further includes working duration; sending first control signals to multiple first target motors respectively, and further includes:

[0106] During the working period, first control signals are sent to multiple first target motors respectively until the end of the working period, or an interrupt signal for the target working mode is obtained.

[0107] This application embodiment also supports users to personalize the working time of the electric seat in the target working mode according to their own needs, such as 15 minutes, 20 minutes, 30 minutes, etc. The specific working time can be set by the user and there is no limitation on it.

[0108] During this working period, the controller will continuously send first control signals to multiple first target motors until the end of the working period.

[0109] Ideally, the electric seat will move continuously for the aforementioned working time. However, in reality, some unexpected situations may inevitably occur, such as motor failure, sensor failure on the motor, or the vehicle on which the electric seat is located is about to be pre-collision, or user adjustments to the electric seat. These will generate an interruption signal for the target working mode, which is used to indicate the cessation of the target working mode to protect safety.

[0110] In some embodiments, the setting information also includes a target swing frequency selected from a plurality of swing frequencies; each motor is a motor carrying feedback information;

[0111] Send first control signals to multiple first target motors respectively, including:

[0112] Obtain the feedback information of each first target motor at the current moment;

[0113] Determine the actual swing frequency of each target direction at the current moment based on the feedback information at the current moment;

[0114] Determine the deviation between the actual sway frequency of each target direction and the target sway frequency at the current moment;

[0115] Based on the deviation values ​​of each target direction at the current moment, the first control signal of the first target motor in each target direction at the next moment is adjusted; the first control signal is used to change at least a portion of the input voltage, input current and duty cycle of the first target motor.

[0116] The rocking frequency of a seat usually refers to the number of times the seat rocks back and forth, left and right, or in other directions per unit of time. The commonly used unit is "Hertz (Hz)," which represents the number of rocking motions per second.

[0117] This application provides multiple selectable swing frequencies for each working mode. The multiple selectable swing frequencies corresponding to different working modes can be the same or different, and there is no limitation on this.

[0118] For example, the swing frequencies corresponding to the Trojan mode include 0.25Hz, 0.16Hz, 0.125Hz, 0.1Hz, and 0.083Hz.

[0119] Different rocking frequencies result in different levels of seat comfort, and different people may experience different levels of comfort at the same rocking frequency. Therefore, users can select a target rocking frequency from multiple rocking frequencies according to their own needs.

[0120] In addition, each motor in the embodiments of this application is a motor carrying feedback information; the feedback information may include the actual speed, actual position, acceleration, etc. of the motor, and may also include other motion parameters.

[0121] Feedback information from the motor can be obtained through sensors carried by the motor, and there are no restrictions on the type of sensor.

[0122] In addition, before the electric seat begins its back-and-forth movement, the controller initializes each of the first target motors with position feedback on the seat, enabling accurate control of each first target motor in the future.

[0123] When the controller controls each first target motor, it will acquire the feedback information of each first target motor in real time. At the current moment, it can determine the actual swing frequency of each target direction at the current moment from the feedback information at the current moment, and determine the deviation value between the actual swing frequency of each target direction and the target swing frequency at the current moment.

[0124] The first control signal of the first target motor in each target direction can be adjusted according to the deviation value of each target direction at the current moment. The first control signal is used to change at least a portion of the input voltage, input current and duty cycle of the first target motor, thereby realizing closed-loop control of the electric motion information, ensuring that the rocking motion of the seat is smooth and stable, and that the system can still accurately maintain the set rocking frequency even under load changes or external environmental influences.

[0125] In some embodiments, the interrupt signal includes a user-triggered seat adjustment signal;

[0126] After receiving the interrupt signal for the target operating mode, the method further includes:

[0127] If the interrupt signal is a seat adjustment signal, stop the target working mode to stop the electric seat from moving back and forth in each target direction;

[0128] The adjustment operation is performed based on the seat adjustment signal.

[0129] As illustrated in the foregoing embodiments, the interrupt signal can be actively triggered by the user. In this case, the interrupt signal is the seat adjustment signal actively triggered by the user. The user can trigger the seat adjustment signal through a hard-wired switch, a software switch, or by voice adjustment, and there are no restrictions on this.

[0130] When the interrupt signal is a seat adjustment signal, the target operating mode is stopped to stop the electric seat from moving back and forth in each target direction. In addition, an adjustment operation is required based on the seat adjustment signal, which can be an adjustment signal for any motor generated based on the user's adjustment operation. For example, the seat adjustment signal is used to adjust the tilt angle of the seat back. The adjustment operation stops after the user stops triggering the seat adjustment signal.

[0131] In some embodiments, the interruption signal further includes a fault signal and a vehicle pre-collision signal; the power seat also includes a second motor for adjusting the tilt angle of the power seat;

[0132] After receiving the interrupt signal for the target operating mode, the method further includes:

[0133] In the event that the interruption signal is a fault signal or a vehicle pre-collision signal, stop the target operating mode to stop the electric seat from moving back and forth in each target direction;

[0134] A second control signal is output to the second motor so that the second motor drives the electric seat to return to the target tilt angle and then to a safe position based on the second control signal.

[0135] As illustrated in the foregoing embodiments, the interruption signal can also be passively triggered, specifically a fault signal and / or a vehicle pre-collision signal (indicating the possibility of a collision).

[0136] Among them, the fault signal can be triggered by a related motor failure (motor speed failure, motor position failure, etc.), and the pre-collision signal can be obtained through equipment such as radar and cameras.

[0137] In the event that the interruption signal is a fault signal or a vehicle pre-collision signal, the target operating mode is stopped to halt the back-and-forth movement of the electric seat in each target direction, thereby preventing a safety accident.

[0138] In addition, a second control signal is output to the second motor. This second control signal also includes at least a portion of the input voltage, input current, and duty cycle of the first target motor, so that after the second motor drives the electric seat back to the target tilt angle based on the second control signal, the electric seat is in a safe position. This target tilt angle is usually a large angle, such as 20 degrees, that is, the backrest is adjusted to a large angle to the safe position.

[0139] In addition, this return operation is usually completed within the target time (e.g., 1 to 2 seconds) to maximize passenger safety and prevent potential safety hazards (such as seat belt strangulation or insufficient restraint).

[0140] In some embodiments, before sending the first control signal to each of the plurality of first target motors, the method further includes:

[0141] Obtain the target position of the electric seat in a zero-gravity posture;

[0142] Based on the initial position of the electric seat;

[0143] Based on the first position deviation between the target position and the initial position, a third control signal is sent to at least some of the multiple first motors and second motors, so that at least some of the motors drive the electric seat to move to the target position based on the corresponding third control signal.

[0144] This embodiment of the electric seat features a zero-gravity posture, which mimics the posture of an astronaut in weightlessness in space. When the seat is adjusted to this posture, the seat cushion and backrest automatically adjust to a specific angle, bringing the user closer to a weightless state. This reduces pressure on the spine and joints, especially in the lower back and hip areas, during prolonged sitting. This posture allows for even distribution of body pressure, promotes blood circulation, reduces fatigue, and enhances comfort.

[0145] Before officially controlling the electric seat to move back and forth, a third control signal can be sent to at least some of the first and second motors based on the first position deviation between the target position in zero gravity (which can be obtained in advance based on experiments) and the initial position of the electric seat. The third control signal also includes at least some of the input voltage, input current and duty cycle of the first target motor, so that at least some motors can drive the electric seat to move to the target position based on the corresponding third control signal, thereby improving the passenger's riding comfort.

[0146] In some embodiments, the method further includes sending a fourth control signal to at least some of the plurality of first motors and second motors before:

[0147] Record the initial position of the electric seat;

[0148] After sending first control signals to multiple target motors until the end of the working time, the method further includes:

[0149] Based on the second position deviation between the actual position and the initial position in the feedback information of each first target motor, a fourth control signal is output to each first target motor so that each first target motor drives the electric seat to return to the initial position based on the fourth control signal.

[0150] As described in the foregoing embodiments, in the absence of an interruption signal, the electric seat will continuously move back and forth during the working time until the end of the working time. After the electric seat stops the target working mode, the controller will output a fourth control signal to the first target motor, so that each first target motor drives the electric seat back to the initial position based on the fourth control signal. The fourth control signal also includes at least a portion of the input voltage, input current and duty cycle of the first target motor.

[0151] In some embodiments, the working modes include a single working mode and multiple working modes; the single working mode indicates a single direction; the single working mode includes a horizontal mode, a rocking horse mode, and a swinging mode;

[0152] In Pingyao mode, the electric seat moves back and forth in the front-to-back direction;

[0153] In Trojan mode, the electric seat moves back and forth in the up and down direction;

[0154] In rocking mode, the electric seat moves back and forth in the left and right directions;

[0155] In multiple operating modes, the electric seat moves back and forth in at least two of the following directions: forward and backward, up and down, and left and right.

[0156] The foregoing embodiments have already described this, and will not be repeated here.

[0157] In some embodiments, after obtaining the settings information input by the user, the method further includes:

[0158] When the target working mode is a single working mode, the second target motor corresponding to the single direction indicated by the single working mode is determined from multiple first motors according to the mapping relationship between direction and motor.

[0159] A fifth control signal is sent to the second target motor so that the second target motor drives the electric seat to move back and forth in a single direction based on the corresponding fifth control signal.

[0160] As described in the previous embodiments, the target working mode can be a multi-working mode or a single working mode. Users can choose a single working mode or a multi-working mode based on their own needs.

[0163] A brushless motor is an electric motor without traditional brushes (carbon brushes in brushed motors). It is an electric motor based on electronic commutation control and features high efficiency and low maintenance.

[0164] A servo motor is an electric motor whose position, speed, and acceleration are controlled by a feedback system. It typically consists of the motor itself, a controller, and a feedback device (such as an encoder or position sensor), and its behavior is adjusted by external control signals during operation.

[0165] In the embodiments of this application, at least some of the motors are brushless motors or servo motors, thereby reducing the noise generated by the back-and-forth movement of the electric seat (noise level less than 40 dB) and providing a quiet operating environment.

[0172] Step 206: Determine whether the target duration has been reached; if yes, proceed to step 208; if no, proceed to step 209.

[0173] Step 207: Determine whether a fault signal and / or vehicle pre-collision signal has been obtained; if yes, proceed to step 211; if no, proceed to step 206.

[0174] Step 208: Stop the target working mode to stop the electric seat from moving back and forth in each target direction, and control the relevant motors to drive the electric seat to the initial position; proceed to step 212.

[0175] Step 209: Determine whether a seat adjustment signal triggered by the user has been received; if yes, proceed to step 210; if no, proceed to step 205.

[0176] Step 210: Stop the target working mode to stop the electric seat from moving back and forth in each target direction, and perform an adjustment operation based on the seat adjustment signal; proceed to step 212.

[0177] Step 211: Stop the target working mode to stop the electric seat from moving back and forth in each target direction. Control the second motor used to adjust the tilt angle of the electric seat so that the electric seat is driven back to the target tilt angle by the second motor and then the electric seat is in a safe position; proceed to step 212.

[0178] Step 212, End.
