[0042] Through the above-mentioned drawings, specific embodiments of the present application have been shown, and there will be more detailed descriptions hereinafter. These drawings and textual descriptions are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. Detailed Description of the Embodiments

[0043] Here, exemplary embodiments will be described in detail, and examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numerals in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0044] When a user uses a vehicle, it involves the opening and closing of the vehicle door.

[0045] In the prior art, for the method of electrically controlling the opening and closing of a vehicle door, a user can control the opening or closing of the vehicle door by pressing a button inside the vehicle.

[0046] In one example, the button for controlling the opening and closing of the vehicle door is set to be the same. For example, when the user presses the button once, the vehicle door opens, and when the user presses the button again, the vehicle door closes.

[0047] However, the above setting method is likely to cause the problem that the operation result of the user is inconsistent with the user's intention. For example, different users have different operation habits. Some users are accustomed to pressing the button once to expect the vehicle door to open and pressing the button twice to close the vehicle door; while for some other users, they are accustomed to pressing and holding the button for a long time to expect to open or close the vehicle door. Therefore, a single button is difficult to meet the operation habits of different users, and thus will cause the problem that the operation result of the user is inconsistent with the user's intention.

[0048] The present application provides a control structure for a vehicle door and a vehicle to solve the above technical problems.

[0049] Figure 1 As shown in the structural schematic diagram of a control structure for a vehicle door provided by an embodiment of the present application, Figure 1 as shown, the control structure includes: a central electronic unit 11 and an electric control door unit 12; wherein, the central electronic unit 11 is communicatively connected to the electric control door unit 12, and the electric control door unit 12 is communicatively connected to the vehicle door.

[0050] The electric control door unit 12 is configured to receive a first sensor signal transmitted by a first sensor 13 on the vehicle door, convert the first sensor signal into a first control signal, and control the closing of the vehicle door according to the first control signal; wherein, the first sensor signal indicates that the vehicle door has moved, and the first control signal indicates controlling the closing of the vehicle door.

[0051] The electric control door unit 12 is further configured to receive a second control signal transmitted by the central electronic unit 11, and control the unlocking or opening of the vehicle door according to the second control signal; wherein, the second control signal indicates controlling the unlocking or opening of the vehicle door.

[0052] Exemplarily, a first sensor 13 is deployed in the vehicle door. When the first sensor 13 detects that the vehicle door has moved, it emits a first sensor signal. When the first sensor deployed in the vehicle door detects that the vehicle door has moved, it indicates that the user has applied a pushing force towards the vehicle when in a state outside the vehicle. Such a pushing action by the user indicates the intention of the user to close the vehicle door. Therefore, when the first sensor 13 detects that the vehicle door has moved, it indicates that the user has the intention to close the vehicle door. Furthermore, the first sensor 13 emits a first sensor signal characterizing the user's intention to close the vehicle door.

[0053] After receiving the first sensor signal, the central electronic unit 11 (Central Electronic Module, CEM) connected to the first sensor 13 converts the first sensor signal into a first control signal and transmits the first control signal to the electric control door unit 12 (Power Operation Door, POD).

[0054] The electric control door unit 12 controls the closing of the vehicle door according to the received first control signal. For example, an actuator is built into the electric control door unit 12. The way the electric control door unit 12 controls the closing of the vehicle door can be: according to the indication of the first control signal, the electric control door unit 12 drives the actuator motor, and the motor realizes the closing of the vehicle door through a mechanical transmission structure. For example, the mechanical transmission structure can be a combination of gears, racks, and linkages. Through the mechanical transmission structure, the rotational motion required to close the vehicle door is converted into a linear motion or other required motions, thereby pushing the vehicle door to close.

[0055] The electric control door unit 12 also receives a second control signal transmitted from the central electronic unit 11, and the second control signal characterizes the user's intention to open the vehicle door; wherein, the user's intention to open the door includes two situations.

[0056] In the first case, the user's intention to open the door is for the door to be opened electrically. In this case, the electric control door unit 12 controls the door to open electrically according to the second control signal. For example, the way the electric control door unit 12 controls the door to open electrically can refer to the aforementioned method of controlling the motor through the actuator to drive the mechanical transmission structure to open the door, which will not be elaborated here.

[0057] In the second case, the user's intention to open the door is for the user to pull the door manually to open the door (referred to as manual opening). In this case, the electric control door unit 12 controls the door to unlock. For example, the electric control door unit 12 activates the actuator, and the motor drives the mechanical structure in the door connected to the locking mechanism, thereby unlocking the locking mechanism; for example, the locking mechanism can be a lock tongue, and a lock hole adapted to the lock tongue is provided in the door, and the drive of the motor causes the lock tongue to retract from the lock hole of the door, thereby realizing the unlocking of the door.

[0058] Among them, the recognition of the user's intention to open the door can be determined by judging the emission time of the second control signal; for example, according to the emission time of different second control signals, different opening intentions of the user are determined.

[0059] After the door is unlocked, the user can pull the outer handle on the door in the direction away from the vehicle to manually open the door.

[0060] In the embodiment of the present application, by respectively setting the link for opening the door and the link for closing the door, when receiving the first control signal indicating that the user has the intention to close the door, the door is controlled to close through the link for opening the door; when receiving the second control signal indicating that the user has the intention to open the door, the door is controlled to open or the door is unlocked through the link for closing the door. Furthermore, when the user has the intention to close the door, the first control signal can be sent to the vehicle by triggering the trigger source related to closing the door, thereby controlling the door to close; when the user has the intention to open the door, the second control signal can be sent to the vehicle by triggering the trigger source related to opening the door, thereby controlling the door to open. Therefore, it will not cause the problem that the opening or closing of the door does not conform to the user's intention after the user adjusts the trigger source, improving the user experience.

[0061] Figure 2 It is a schematic structural diagram of another control structure of the door provided by the embodiment of the present application, as Figure 2 shown, the control structure includes: a central electronic unit 11 and an electric control door unit 12; wherein, the central electronic unit 11 is communicatively connected to the electric control door unit 12, and the electric control door unit 12 is communicatively connected to the door.

[0062] The electric control door unit 12 is configured to receive a first sensor signal transmitted by a first sensor 13 on the vehicle door, convert the first sensor signal into a first control signal, and control the closing of the vehicle door according to the first control signal; wherein, the first sensor signal indicates that the vehicle door has moved, and the first control signal indicates controlling the closing of the vehicle door.

[0063] The electric control door unit 12 is further configured to receive a second control signal transmitted by the central electronic unit 11, and control the unlocking or opening of the vehicle door according to the second control signal; wherein, the second control signal indicates controlling the unlocking or opening of the vehicle door.

[0064] In one example, the first sensor 13 is a pressure sensor, and the first sensor signal indicates that the pressure received by the vehicle door is greater than a preset pressure.

[0065] Alternatively, the first sensor 13 is a displacement sensor, and the first sensor signal indicates that the distance the vehicle door has moved is greater than a preset distance.

[0066] Exemplarily, the first sensor 13 may be a pressure sensor. The pressure sensor is deployed in the vehicle door and continuously monitors the pressure value received by the vehicle door. When the user pushes the vehicle door in the direction towards the vehicle, the user applies pressure to the vehicle door, causing a change in the pressure received by the vehicle door, and consequently, the pressure value monitored by the pressure sensor also changes accordingly.

[0067] In one case, when the pressure value monitored by the pressure sensor is greater than the preset pressure value, the pressure sensor sends a first sensor signal to the electric door control unit 12.

[0068] In another case, the pressure sensor converts the monitored pressure value into a first sensor signal and sends it to the electric door control unit 12; if the electric door control unit 12 determines that the pressure value of the vehicle door indicated by the first sensor signal is greater than the preset pressure value, it generates a first control signal and controls the closing of the vehicle door according to the first control signal.

[0069] In addition, the first sensor 13 may also be a displacement sensor. The displacement sensor may be deployed on the hinge of the vehicle door to monitor the displacement of the vehicle door. When the user pushes the vehicle door in the direction towards the vehicle, the hinge of the vehicle will rotate, thereby causing a change in the displacement value monitored by the displacement sensor deployed on the hinge of the vehicle; wherein, the displacement of the vehicle door may be the relative displacement of the current position of the vehicle door with respect to the initial position of the vehicle door (the position when the vehicle door is fully closed).

[0070] In one case, when the displacement value of the vehicle door monitored by the displacement sensor is greater than the preset distance, it indicates that the user has applied a push towards the vehicle direction to the vehicle door and has the intention to close the vehicle door. Consequently, the displacement sensor sends a first sensor signal to the electric door control unit 12.

[0071] In another case, the displacement sensor converts the monitored displacement value of the vehicle door into a first sensor signal; when the electric door control unit 12 determines that the moving distance of the vehicle door represented by the first sensor signal is greater than a preset distance, a first control signal is generated, and the vehicle door is controlled to close according to the first control signal.

[0072] In one example, the control structure further includes: a button 14 inside the vehicle; the button 14 is communicatively connected to the central electronic unit 11.

[0073] The central electronic unit 11 is configured to receive a second control signal transmitted by the button 14.

[0074] Exemplarily, the button 14 is deployed inside the vehicle. For example, the button 14 may be deployed in the B-pillar area inside the vehicle door. When the user presses the button 14, the state of the button 14 changes, and then a second control signal is sent to the central electronic unit 11.

[0075] After receiving the second control signal sent by the button 14, the central electronic unit 11 transmits the second control signal to the electric door control unit 12, thereby controlling the vehicle door to open.

[0076] In one example, the central electronic unit 11 is configured to receive a second control signal transmitted by the outside handle 15 on the vehicle door.

[0077] The second control signal indicates that the duration of the user pulling the outside handle 15 is less than or equal to a preset duration and indicates controlling the vehicle door to open; or, the second control signal indicates that the duration of the user pulling the outside handle 15 is greater than the preset duration and indicates controlling the vehicle door to unlock.

[0078] In one example, a microswitch is provided on the outside handle 15, and the microswitch is communicatively connected to the central electronic unit 11.

[0079] The microswitch is used to detect whether the user pulls the outside handle 15.

[0080] Exemplarily, the user pulls the outside handle 15 in a direction away from the vehicle, so that the outside handle 15 generates a second control signal and sends it to the central electronic unit 11.

[0081] The central electronic unit 11 monitors the duration of the second control signal sent by the outside handle 15. If it is determined that the duration of the second control signal sent by the outside handle 15 is less than or equal to the preset duration, it indicates that the user's intention is to open the vehicle door electrically, then the second control signal indicates controlling the vehicle door to open, and then the electric control door unit 12 controls the vehicle door to open electrically. The specific process of controlling the vehicle door to open electrically can refer to the content in Embodiment 1. Among them, the preset duration can be 3 seconds.

[0082] If the central electronic unit 11 determines that the duration of the second control signal sent by the outer door handle 15 is greater than a preset duration, it indicates that the user's intention is to open the door manually. Then, the second control signal represents controlling the door to unlock, and further, the electric control door unit 12 only controls the door to unlock. After the door is unlocked, the user applies a pulling force through the lower outer door handle 15, thereby achieving the manual opening of the door. Among them, the method of controlling the door to unlock can refer to the relevant content in the first embodiment.

[0083] For example, a micro switch can be provided in the outer door handle 15. The micro switch includes an internal circuit and two contact points. For example, the two contact points are the first contact point and the second contact point respectively, and the first contact point and the second contact point are respectively connected to different internal circuits (for example, open circuit and closed circuit). For example, when the user does not pull the outer door handle 15, the first contact point is connected to the open circuit of the internal circuit, and no second control signal is sent. When the user pulls the outer door handle 15, the first contact point is connected to the closed circuit of the internal circuit, and then the second control signal is sent. Such a change in the contact point causes the state of the internal circuit to be different. Then, in the state where the internal circuit is connected in a closed circuit, the micro switch sends the second control signal through the outer door handle 15.

[0084] A capacitance switch can also be provided in the outer door handle 15. The capacitance switch includes a capacitor and a capacitance detection circuit. When the user's hand touches the capacitance switch, the capacitance value of the capacitance switch changes. For example, the capacitance value increases. The change in the capacitance value of the capacitance switch can be detected by the capacitance detection circuit. Then, the capacitance detection circuit converts the change in the capacitance value into a second control signal, and thus sends the second control signal through the outer door handle 15.

[0085] In one example, the control structure further includes: a human-machine interaction unit 16; the human-machine interaction unit 16 is communicatively connected to the central electronic unit 11.

[0086] The central electronic unit 11 is configured to receive the third control signal transmitted by the human-machine interaction unit 16 and transmit the third control signal to the electric control door unit 12 through the central electronic unit 11 for processing. Among them, the third control signal represents controlling the door to open or close.

[0087] In one example, the control structure further includes: a control screen 17 inside the vehicle; control buttons 18 are displayed on the control screen 17, and the control screen 17 is communicatively connected to the human-machine interaction unit 16.

[0088] The control button 18 is configured to transmit the third control signal to the human-machine interaction unit 16 when triggered.

[0089] In one example, the control structure further includes: a sensing camera 19; the sensing camera 19 is communicatively connected to the human-machine interaction unit 16.

[0090] The sensing camera 19 is configured to transmit gesture images to the human-machine interaction unit 16; wherein, the gesture images are used to generate a third control signal.

[0091] Exemplarily, the control structure further includes a human-machine interaction unit 16 (Display and Human Interface Unit, DHU), the human-machine interaction unit 16 is communicatively connected to the central electronic unit 11, and the control screen 17, the sensing camera 19 are communicatively connected to the human-machine interaction unit 16. Wherein, at least one control button 18 is provided on the control screen 17, for example, a control button 18 representing opening the door and a control button 18 representing closing the door; the user clicks the control button 18 representing opening the door on the control screen 17, and the control button 18 representing opening the door transmits a third control signal to the human-machine interaction unit 16, and the third control signal indicates the user's intention to open the vehicle door; the human-machine interaction unit 16 sequentially transmits the third control signal to the central electronic unit 11 and the electric control door unit 12, and the electric control door unit 12 controls the vehicle door to open; the user clicks the control button 18 representing closing the door on the control screen 17, and the control button 18 representing opening the door transmits a third control signal to the human-machine interaction unit 16, and the third control signal indicates the user's intention to close the vehicle door; the human-machine interaction unit 16 sequentially transmits the third control signal to the central electronic unit 11 and the electric control door unit 12, and the electric control door unit 12 controls the vehicle door to open.

[0092] The control structure further includes a sensing camera 19, and the sensing camera 19 is communicatively connected to the human-machine interaction unit 16. The sensing camera 19 continuously monitors the gesture images of the user inside the vehicle and transmits the obtained gesture images to the human-machine interaction unit 16.

[0093] The human-machine interaction unit 16 compares the gesture image with the pre-stored gesture image, where the pre-stored gesture image can be a "V" gesture; if the human-machine interaction unit 16 determines that the gesture image of the user obtained is consistent with the pre-stored gesture image, the human-machine interaction unit 16 sends a third control signal to the central electronic unit 11. Among them, if the gesture image of the user is consistent with the gesture image representing opening the car door in the pre-stored gesture image, the third control signal indicates the user's willingness to open the car door, and the human-machine interaction unit 16 sequentially sends the third control signal to the central electronic unit 11 and the electric control door unit 12, and the electric control door unit 12 controls the car door to open; if the human-machine interaction unit 16 determines that the gesture image of the user is consistent with the gesture image representing closing the car door in the pre-stored gesture image, the third control signal indicates the user's willingness to close the car door, and the human-machine interaction unit 16 sequentially sends the third control signal to the central electronic unit 11 and the electric control door unit 12, and the electric control door unit 12 controls the car door to close.

[0094] In an example, the control structure further includes: a second sensor 20 and a door anti-collision radar 21; where the second sensor 20 is a rain sensor; the second sensor 20 and the door anti-collision radar 21 are respectively communicatively connected to the central electronic unit 11.

[0095] The electric control door unit 12 is further configured to receive the rain signal transmitted by the second sensor 20 and the obstacle detection signal transmitted by the door anti-collision radar 21, generate a fourth control signal according to the rain signal and the obstacle detection signal; and control the car door to open according to the fourth control signal.

[0096] Among them, the rain signal represents the amount of rain in the external environment of the vehicle, and the obstacle detection signal represents whether there is an obstacle near the car door; the fourth control signal represents controlling the car door to open, and the fourth control signal indicates the opening degree of the car door.

[0097] Exemplarily, the control structure further includes a second sensor 20 deployed in the vehicle, and the second sensor 20 is communicatively connected to the central electronic unit 11. For example, the second sensor 20 is a rain sensor (Rain and Light Sensor Module, RLSM), and the rain sensor continuously monitors the rain outside the vehicle, generates and sends a rain signal to the central electronic unit 11; among them, the rain signal includes the amount of rain in the external environment of the vehicle.

[0098] Among them, the principle of the rain sensor generating a rain signal is as follows: The rain sensor includes a transmitter and a receiver. The transmitter emits a beam of light, which irradiates the windshield of the vehicle. The windshield reflects the beam of light, and the receiver receives the beam of light reflected by the windshield. The receiver determines the current rainfall by analyzing the reflection path of the reflected beam of light. Specifically: During the reflection process of the windshield, if the windshield is in a dry state, the difference between the reflection path of the reflected beam of light and the preset reflection path is less than the preset first threshold, indicating that the windshield is in a dry state and the rainfall is 0.

[0099] If there are raindrops on the windshield, the reflected beam of light will be scattered, that is, there is a large difference (greater than or equal to the preset first threshold) between the reflection path of the reflected beam of light and the preset reflection path (the reflection path of the beam of light emitted in the dry state); the greater the rainfall, the greater the degree of the above difference; then the amount of rainfall can be determined according to the size of the difference value.

[0100] Among them, the corresponding relationship between the above difference value and the amount of rainfall can be obtained by looking up the experimental curve.

[0101] The control structure further includes a door anti-collision radar 21 (Door Radar Module, DRM) deployed on the door, and the door anti-collision radar 21 is communicatively connected to the central electronic unit 11. The door anti-collision radar 21 monitors the obstacles near the door, generates and sends an obstacle detection signal to the central electronic unit 11; among them, the obstacle detection signal indicates whether there are obstacles near the door.

[0102] Among them, the principle of the door anti-collision radar 21 generating an obstacle detection signal is as follows:

[0103] The door anti-collision radar 21 includes an ultrasonic transmitter, an ultrasonic receiver, and a microprocessor. The ultrasonic transmitter emits ultrasonic waves, and the ultrasonic receiver receives the reflected ultrasonic waves; after the ultrasonic transmitter emits ultrasonic waves, the microprocessor records the emission time; the emitted ultrasonic waves propagate in the air, and when they encounter an obstacle, the ultrasonic waves are reflected by the obstacle; the ultrasonic receiver receives the reflected ultrasonic waves, and the microprocessor records the reception time; the microprocessor calculates the distance between the obstacle and the door according to the emission time and the reception time; specifically, it can be calculated by the following formula:

[0104]

[0105] The microprocessor determines whether there is an obstacle with a collision risk outside the vehicle door by comparing the calculated distance with a preset safe distance. Specifically: If the calculated distance is less than the preset safe distance, there is an obstacle with a collision risk outside the vehicle door, and the door anti-collision radar 21 generates an obstacle detection signal and transmits it to the central electronic unit 11; If the calculated distance is greater than or equal to the safe distance, there is no obstacle with a collision risk outside the vehicle door, and the door anti-collision radar 21 does not generate an obstacle detection signal.

[0106] The central electronic unit 11 generates and sends a fourth control signal to the electric control door unit 12 based on the received rain signal and obstacle detection signal; Among them, the fourth control signal indicates the user's intention to open the door and indicates the opening angle of the door (i.e., the opening degree of the door).

[0107] For example, the central electronic unit 11 determines the current rainfall intensity according to the magnitude of the rainfall indicated in the rain signal, where the rainfall intensity includes light rain, moderate rain, and heavy rain.

[0108] If it is determined that the rainfall indicated in the rain signal is less than or equal to the first rainfall amount, it is determined that the current rainfall intensity is light rain; If it is determined that the rainfall indicated in the rain signal is greater than the first rainfall amount and less than or equal to the second rainfall amount, it is determined that the current rainfall intensity is moderate rain; If it is determined that the rainfall indicated in the rain signal is greater than the third rainfall amount, it is determined that the current rainfall intensity is heavy rain. Among them, the values of the first rainfall amount, the second rainfall amount, and the third rainfall amount can be determined according to historical data or expert opinions, etc.

[0109] If the central electronic unit 11 does not receive an obstacle detection signal, it determines the opening angle of the door in the fourth control signal according to the rain signal. For example, if the rainfall intensity is light rain, it is determined that the opening degree of the door is the first opening angle, where the first opening angle can be 80% of the opening angle of the door relative to the fully opened angle of the door; If the rainfall intensity is moderate rain, it is determined that the opening degree of the door is the second opening angle, where the second opening angle can be 50% of the opening angle of the door relative to the fully opened angle of the door; If the rainfall intensity is heavy rain, it is determined that the opening degree of the door is the third opening angle, where the third opening angle can be 30% of the opening angle of the door relative to the fully opened angle of the door.

[0110] If the central electronic unit 11 receives a rainfall signal and an obstacle detection signal, it determines the opening angle of the vehicle door in the fourth control signal based on the rainfall intensity determined from the rainfall signal and the obstacle detection signal. For example, first, the maximum safe opening angle of the vehicle door is calculated based on the obstacle detection signal. Next, the central electronic unit 11 compares the opening angles of the vehicle door determined from the rainfall signal (i.e., the first opening angle, the second opening angle, and the third opening angle) with the maximum safe opening angle of the vehicle door, and takes the smaller of the two as the opening degree of the vehicle door. For example, if the central electronic unit 11 determines that the first opening angle is greater than the maximum safe opening angle of the vehicle door, the maximum safe opening angle of the vehicle door is taken as the opening degree of the vehicle door; the electric control door unit 12 controls the vehicle door to open to the opening degree of the vehicle door.

[0111] In the embodiment of the present application, by separately setting the link for opening the vehicle door and the link for closing the vehicle door, when receiving the first control signal indicating that the user has the intention to close the door, the vehicle door is controlled to close through the link for opening the vehicle door; when receiving the second control signal indicating that the user has the intention to open the door, the vehicle door is controlled to open or the vehicle door is unlocked through the link for closing the vehicle door. Furthermore, when the user has the intention to close the vehicle door, the first control signal can be sent to the vehicle by triggering the trigger source related to closing the vehicle door, thereby controlling the vehicle door to close; when the user has the intention to open the vehicle door, the second control signal can be sent to the vehicle by triggering the trigger source related to opening the vehicle door, thereby controlling the vehicle door to open. Therefore, the problem that the opening or closing of the vehicle door does not conform to the user's intention after the user adjusts the trigger source will not occur, improving the user experience.

[0112] In addition, in the embodiment of the present application, after deploying a rain sensor to monitor the amount of rainfall, the rainfall intensity is determined, and the opening angle of the vehicle door is determined according to the rainfall intensity; after deploying the vehicle door anti-collision radar 21 to monitor the obstacles near the vehicle door, an obstacle detection signal is generated, and the maximum safe opening angle of the vehicle door is calculated according to the obstacle detection signal; the opening angle of the vehicle door determined according to the rainfall intensity and the maximum safe opening angle of the vehicle door are taken as the smaller value of the two as the opening degree of the vehicle door, which can not only reduce the possibility of rainwater entering the vehicle in rainy days, but also avoid collisions between the vehicle door and the obstacles near the vehicle door during the opening process of the vehicle door, thereby improving the user experience.

[0113] In addition, in the embodiments of the present application, by monitoring the duration of the user pulling the outer handle and determining different ways of opening the vehicle door according to different durations of pulling the outer handle, the need of the user to quickly open the door is satisfied. Specifically, if the duration of the user pulling the outer handle is less than or equal to a preset duration, the vehicle door is opened electrically, and such an electrically opened vehicle door usually takes more than 3 seconds; if the duration of the user pulling the outer handle is greater than the preset duration, only the vehicle door is unlocked, and after the vehicle door is unlocked, the user applies a pulling force to the outer handle to open the vehicle door, and such a manually opened vehicle door is faster than the electrically opened vehicle door (usually can be achieved within 1 second); moreover, when the user is eager to open the vehicle door and pulls the vehicle door handle outwards for a long time, it conforms to the user's current mood and intuitive reaction, satisfying the user's need to quickly open the vehicle door in an emergency state.

[0114] The embodiments of the present application provide a vehicle, and the vehicle is provided with the control structure as provided in the above embodiments.
