[0010] In an optional embodiment, when the control instruction is a tailgate glass closing instruction, the control logic includes the following steps: when the tailgate glass closing instruction is received, obtaining the current status of the tailgate lower flip lock and the tailgate side unlock; when the current status of the tailgate lower flip lock and the tailgate side unlock are both locked, issuing a glass rise start instruction to drive the glass adjustment device to perform the rising action; obtaining the current status of the roof; when the current status is a fully closed state, determining whether the tailgate glass has reached a preset upper hard stop point, and when the tailgate glass reaches the upper hard stop point, issuing a glass rise stop instruction to drive the glass adjustment device to stop the rising action; when the current status is not a fully closed state, determining whether the tailgate glass has reached a preset third soft stop point, and when the tailgate glass reaches the third soft stop point, issuing a glass rise stop instruction to drive the glass adjustment device to stop the rising action.

[0011] In this way, the tailgate glass can be raised by operating the switch with one button, and the tailgate side unlocking and locking signals, the tailgate lower lock and locking signals and the roof position signals can be detected and judged at the same time, so that the tailgate glass can be raised to the target position.

[0012] In an optional embodiment, when the control instruction is a tailgate glass closing and roof closing instruction, the control logic includes the following steps: when a tailgate glass closing and roof closing instruction is received, a roof closing start instruction is issued to drive the roof adjustment device to perform a closing action; it is determined whether the roof has reached a preset fully closed position; when the roof reaches the fully closed position, the current status of the tailgate lower flip lock and the tailgate side unlock is obtained; when the current status of the tailgate lower flip lock and the tailgate side unlock are both locked, a glass rising start instruction is issued to drive the glass adjustment device to perform a rising action; when the tailgate glass reaches the upper hard stop point, a glass rising stop instruction is issued to drive the glass adjustment device to stop the rising action.

[0013] In this way, the roof can be closed by operating the switch with one button, and at the same time, the tailgate side unlocking and locking signals and the tailgate lower lock signals can be detected and judged to control the rise of the tailgate glass, so that the roof and tailgate glass can be closed with one button.

[0014] In an optional embodiment, when the control instruction is a side door opening and closing instruction, the control logic includes the following steps: when the side door opening and closing instruction is received, the current state of the tailgate lower flip lock is obtained; when the current state of the tailgate lower flip lock is a locked state, the current instruction of the side door is determined according to the side door opening and closing instruction, wherein the current instruction of the side door is to open the side door or to close the side door; when the current instruction of the side door is to open the side door, the current state of the tailgate side unlocking is obtained; when the current state of the tailgate side unlocking is a locked state, a glass rising start instruction is issued to drive the glass adjusting device to perform the rising action; when the tailgate glass rises to a preset fourth When the back door is at the soft stop point, the back door side unlocking is controlled to be in the unlocking state; a side door opening start command is issued to drive the back door side opening adjustment device to perform the opening action. When the side door is at the preset fifth soft stop point, a side door opening stop command is issued to drive the back door side opening adjustment device to stop the opening action, and the current state of the side door is recorded. When the current command of the side door is to close the side door, a side door closing start command is issued to drive the back door side opening adjustment device to perform the closing action. When the current state of the back door side unlocking is the locked state, a side door closing stop command is issued to drive the back door side opening adjustment device to stop the closing action, and the current state of the side door is recorded.

[0064] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of the present invention.

[0065] According to an embodiment of the present invention, an embodiment of a car tailgate control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0066] In this embodiment, a method for controlling a car back door is provided, which can be used in a computer device. Figure 1 FIG. 1 is a flow chart of a method for controlling a car back door according to an embodiment of the present invention. Figure 1 As shown, the process includes the following steps:

[0067] Step S101: Acquire a control instruction, wherein the control instruction includes any one of the following: tailgate glass down, tailgate glass down and roof open, tailgate glass closed, tailgate glass closed and roof closed, side door open and close, tailgate open and close.

[0068] Specifically, the user can send control commands through the vehicle's central control screen or buttons in the mobile phone APP, voice control system, car keys, hard switches, etc. This embodiment does not impose any specific restrictions on the sending end of the control command, as long as it can send the control command.

[0069] Step S102: Selecting control logic according to the control instruction.

[0070] Specifically, the control logic corresponding to each control instruction is preset in the computer device.

[0071] Step S103: controlling the actuator according to the control logic, wherein the actuator includes at least one of the following: a glass adjustment device, a roof adjustment device, a tailgate side opening adjustment device, and a tailgate downward adjustment device.

[0072] Specifically, the glass adjustment device may be a glass lifter; the roof adjustment device may be a roof motor; the back door side opening adjustment device may be a side opening electric drive; and the back door downward adjustment device may be an electric downward support rod.

[0073] This embodiment provides a variety of control command combinations, such as lowering the back door glass and opening the roof, which can flexibly control the back door and related structures according to the needs of different scenarios, significantly improving the user's convenience and operational freedom in daily use; and the car back door is no longer limited to a single opening method, and can achieve multi-level expansion of space. For example, when it is necessary to load large items, the back door glass and the roof can be opened at the same time, effectively expanding the space at the rear of the car; and when only small items need to be taken in and out, only the back door glass can be opened, saving space and energy. Furthermore, through the unified control system, multiple actuators (such as glass lifters, roof motors, side opening electric drives, and downward flip electric struts) are coordinated and controlled, which not only improves the system integration, but also enhances the compatibility between various functional modules, which is conducive to the optimized design of the vehicle's electronic and electrical architecture.

[0074] The automobile back door control method of this embodiment is applicable to six different usage scenarios, and each usage scenario is described in detail below.

[0075] Use scenario 1: Back door glass lowering

[0076] Figure 2 FIG. 1 is a flow chart of a method for controlling the lowering of a back door glass according to an embodiment of the present invention. Figure 2 As shown, the method for controlling the lowering of the back door glass includes the following steps:

[0077] Step S201: When a tailgate glass lowering instruction is received, the current status of the tailgate downward flip lock and the tailgate side unlock is obtained.

[0078] The purpose of obtaining the current status of the tailgate down-flip lock and the tailgate side unlock is to determine whether the tailgate and the side doors are in a closed state. The tailgate glass can be lowered only when both the tailgate and the side doors are in a closed state.

[0079] Step S202: When the current states of the tailgate lower flip lock and the tailgate side unlock are both locked, a glass lowering start instruction is issued to drive the glass regulating device to perform a lowering action.

[0080] When one of the current states of the tailgate lower flip lock and the tailgate side unlock is not the locked state, the process ends.

[0081] Step S203: When the back door glass reaches the lower hard stop point, a glass descent stop instruction is issued to drive the glass adjustment device to stop the descent action.

[0082] Before step S203, the method further includes determining whether the back door glass has reached the lower hard stop point. For example, whether the back door glass has reached the lower hard stop point can be determined by a sensor detection method, a motor current detection method, or a time / travel estimation method.

[0083] Specifically, the sensor detection method is to install a position sensor (such as a Hall sensor, encoder, etc.) on the back door glass or the drive mechanism to detect the opening and closing angle or displacement of the back door glass in real time. The control module (such as a BCM or a dedicated motor controller) determines whether the current back door glass has reached the lower hard stop point based on the signal feedback from the sensor.

[0084] The motor current detection method involves detecting when the tailgate glass approaches the closed position, which encounters resistance (such as pressure from the sealing strip), increasing the motor load and current. The control module then monitors the motor current trend to determine whether the vehicle is approaching the lower hard stop point. When the current reaches a set threshold, the lower hard stop point is considered reached and the corresponding control strategy is implemented.

[0085] The time / travel extrapolation method records the time or number of motor rotation steps from opening to the next hard stop point during the system calibration phase; during actual operation, it estimates whether the tailgate glass has reached that position by timing or accumulating the number of pulses.

[0086] Figure 3 1 is a flow chart of an example of a method for controlling the lowering of a back door glass according to an embodiment of the present invention. In this example, a short press of the switch 601 enables the lowering of the back door glass 502 with one key. Figure 4 Schematic diagram of the roof closing, glass lowering, and back door closing according to an embodiment of the present invention. Figure 3 As shown, the method for controlling the lowering of the back door glass includes the following steps:

[0087] S1: When the vehicle is unlocked, short press (≤ preset time) the switch 601, the controller 901 receives the current signal from the switch 601 and executes step S2;

[0088] S2: The controller 901 determines the locking signals of the tailgate lower flip lock 203 and the tailgate side unlock 303. If the tailgate lower flip lock 203 and the tailgate side unlock 303 are not all locked, no actuator performs any action and the process ends. If the tailgate lower flip lock 203 and the tailgate side unlock 303 are all locked, step S3 is executed.

[0089] S3: The controller 901 issues a command, the window lifter performs a downward movement, and feeds back a motor operating signal to the controller 901 in real time. The operating signal is a current signal, and step S4 is executed.

[0090] S4: The controller 901 determines in real time whether the glass lifter 501 has reached the hard stop point below the back door glass. If so, step S5 is executed; if not, step S3 is continued.

[0091] S5: The controller 901 issues a command, the window lifter stops descending, and the process ends.

[0092] The car back door control method of this embodiment controls the back door glass to descend by operating a switch with one button, thereby lowering the height of the back door for taking objects and forming a window for taking objects, making it easier for users to take and put objects.

[0093] Use scenario 2: The back door glass is lowered and the roof is open

[0094] Figure 5 FIG. 1 is a flow chart of a method for controlling the lowering of the back door glass and the opening of the roof according to an embodiment of the present invention. Figure 5 As shown, the control method for lowering the tailgate glass and opening the roof includes the following steps:

[0095] Step S501: When a tailgate glass lowering and roof opening instruction is received, a glass lowering start instruction is issued to drive the glass regulating device to perform a lowering action.

[0096] Step S502: When the back door glass reaches the first soft stop point, a roof opening start instruction is issued to drive the roof adjustment device to perform the opening action.

[0097] Before step S502 , the method further includes: determining whether the back door glass has reached a first soft stop point. For example, determining whether the back door glass has reached the first soft stop point can be achieved through a sensor detection method, a motor current detection method, or a time / travel estimation method.

[0098] Step S503: When the roof reaches the second soft stop point, a roof opening stop command is issued to drive the roof adjustment device to stop opening; when the tailgate glass reaches the lower hard stop point, a glass lowering stop command is issued to drive the glass adjustment device to stop lowering.

[0099] Before step S503 , the process also includes determining whether the roof has reached a preset second soft stop point and whether the back door glass has reached a preset lower hard stop point.

[0100] That is to say, the control logic of the tailgate glass lowering and the roof opening is: control the tailgate glass to lower, and after the tailgate glass lowers to the first soft stop point, open the roof, and continue to control the tailgate glass to lower to the hard stop point.

[0101] Figure 61 is a flow chart of an example of a method for controlling the lowering of the back door glass and the opening of the roof according to an embodiment of the present invention. In this example, long pressing the switch 601 causes the lowering of the back door glass 502 and the opening of the roof 401. Figure 7 Schematic diagram of the roof opening, glass lowering, and back door closing according to an embodiment of the present invention. Figure 6 As shown, the control method for lowering the tailgate glass and opening the roof includes the following steps:

[0102] S1: When the vehicle is unlocked, long press (> preset time) the switch 601; the controller 901 receives the current signal from the switch 601 and executes step S2;

[0103] S2: The controller 901 issues a command, the window lifter 501 performs a downward movement, and feeds back a motor operating signal (current signal) to the controller 901 in real time; steps S3-1 and S3-2 are executed simultaneously;

[0104] S3-1: The controller 901 determines the position of the back door glass 502. If the back door glass position satisfies the first soft stop point (i.e., the upper soft stop point in the figure), opening the side door will not interfere with the roof, and the controller executes step S4-1. If the glass position does not meet the requirements, the controller executes step S2.

[0105] S3-2: The controller 901 determines whether the back door glass position satisfies 100% opening (i.e., whether the back door glass reaches the lower hard stop point in the figure). If not, the controller 901 executes step S2; if so, the controller 901 executes step S4-2.

[0106] S4-1: The controller 901 issues a command, the motor of the roof 401 starts, and the motor working signal is fed back to the controller 901 in real time. The working signal is a current signal, and step S5-1 is executed;

[0107] S4-2: The controller 901 issues a command and the window lifter stops descending.

[0108] S5: The controller 901 determines whether the switch 601 is valid. If valid, the controller 901 executes step S8-1; if invalid, the controller 901 executes step S6;

[0109] By determining whether switch 601 is active, it is possible to detect whether the user has issued an instruction to stop or interrupt the operation, thereby determining the next operation process. Specifically, if switch 601 is pressed, that is, switch 601 is active, indicating that the user wishes to terminate the current action; if the switch is inactive, it indicates that the user has not intervened and the system continues to execute the current operation.

[0110] S6: The controller 901 compares the current value of the roof 401 opening with the preset current threshold in real time. If the current value of the current signal does not exceed the preset current threshold, step S4-1 is continued; if the current value of the current signal exceeds the preset current threshold, step S7 is executed;

[0111] S7: The controller 901 determines in real time whether the roof 401 meets the second soft stop point, where the second soft stop point is the maximum soft stop point of the roof. If it meets the second soft stop point, step S8-1 is executed; if not, step S8-2 is executed.

[0112] S8-1: The controller 901 issues a command, the roof 401 stops opening, and the process ends;

[0113] S8-2: The controller 901 sends a command, the motor of the roof 401 reverses, and the motor stops after the roof 401 moves back 100 mm, ending the process.

[0114] according to Figure 6 As can be seen from S6, S7, S8-1, and S8-2, the controller 901 monitors the motor current value of the roof 401 in real time and compares it with a preset current threshold. If the motor current value of the roof 401 does not exceed the preset current threshold, the system will continue to execute step S4-1, that is, continue the opening action. This means that as long as the current remains within a safe range, the roof will continue to open until a certain stop condition is reached. If the motor current value of the roof 401 exceeds the preset current threshold, it may indicate an overload or other abnormal condition. At this point, the controller 901 will enter step S7 to further determine whether the roof has reached the second soft stop point. If, in step S7, it is determined that the roof has reached the second soft stop point (i.e., the maximum soft stop point for the roof to open), S8-1 will be executed, that is, the controller 901 will issue a command to stop the roof opening action, ending the entire process. If, in step S7, the roof has not yet reached the second soft stop point, to prevent possible damage or danger, the system will execute S8-2. The controller 901 will issue a command to reverse the motor of the roof, causing the roof to move back 100 mm, and then stop the movement as a protective measure.

[0115] The control logic described above is primarily designed to ensure safe roof operation. By monitoring the motor's operating status (measured by current), the system intelligently determines whether to continue operating, stop, or initiate protective measures (such as reversing). This design not only enhances system safety but also effectively protects the device from potential damage. It also demonstrates the importance placed on user safety and device protection in modern vehicle control systems.

[0116] exist Figure 6In the control method for lowering the tailgate glass and opening the roof shown, S3-2 and S4-2 are intended to ensure that after the tailgate glass lowers to the first soft stop point, the tailgate glass can continue to be controlled to lower to the hard stop point.

[0117] The car tailgate control method provided in this embodiment controls the tailgate glass lifter to descend with one click by operating a switch, and simultaneously slides the roof system forward to open, forming a cargo box-like space that can be expanded in height, making it easier for users to transport large items.

[0118] Use scenario three: back door glass closed

[0119] Figure 8 FIG. 1 is a flow chart of a back door glass closing control method according to an embodiment of the present invention. Figure 8 As shown, the method for controlling the closing of the back door glass includes the following steps:

[0120] Step S801: When a tailgate glass closing instruction is received, the current status of the tailgate down-lock and the tailgate side unlock is obtained.

[0121] and Figure 2 The method is similar to that of obtaining the current status of the back door down lock and the back door side unlocking in order to determine whether the back door and the side door are in the closed state. The back door glass can be closed only when both the back door and the side door are in the closed state.

[0122] Step S802: When the current states of the tailgate lower flip lock and the tailgate side unlock are both locked, a glass raising start instruction is issued to drive the glass regulating device to perform an raising action.

[0123] Step S803: Acquire the current state of the roof.

[0124] Step S804: When the current state is the fully closed state, determine whether the back door glass reaches the preset upper hard stop point. When the back door glass reaches the upper hard stop point, issue a glass rise stop instruction to drive the glass adjustment device to stop the rise action.

[0125] Step S805: When the current state is not the fully closed state, determine whether the back door glass reaches the preset third soft stop point. When the back door glass reaches the third soft stop point, issue a glass rise stop instruction to drive the glass adjustment device to stop the rise action.

[0126] The third soft stop point of the back door glass and the second soft stop point of the back door glass may be at the same position.

[0127] In other words, the state of the roof determines the height to which the tailgate glass can rise. When the roof is fully closed, the tailgate glass can rise to the upper hard stop point. When the roof is not fully closed, the tailgate glass can rise to the third soft stop point.

[0128] Figure 9 1 is a flow chart of an example of a method for controlling the closing of a back door glass according to an embodiment of the present invention. In this example, a short press of the switch 602 enables the back door glass 502 to rise with one key. Figure 10 Schematic diagram of the roof opening, glass soft stop, and back door closing according to an embodiment of the present invention. Figure 9 As shown, the method for controlling the closing of the back door glass includes the following steps:

[0129] S1: When the vehicle is unlocked, short press (≤ preset duration) the switch 602, the controller 901 receives the current signal from the switch 602 and executes step S2;

[0130] S2: The controller 901 determines the locking signals of the tailgate lower flip lock 203 and the tailgate side unlock 303. If the tailgate lower flip lock 203 and the tailgate side unlock 303 are not all locked, no actuator performs any action and the process ends. If the tailgate lower flip lock 203 and the tailgate side unlock 303 are all locked, step S3 is executed.

[0131] S3: The controller 901 issues a command; the glass lifter 501 performs the glass raising action, and the glass lifter 501 continuously feeds back the motor raising current signal to the controller 901, and then executes step S4;

[0132] S4: The controller 901 determines whether the switch 602 is valid. If not, the controller 901 executes step S5; if valid, the controller 901 executes step S8-1.

[0133] and Figure 6 Similarly, by determining whether switch 602 is active, it is possible to detect whether the user has issued an instruction to stop or interrupt the operation, thereby determining the next step in the operation process. Specifically, if switch 602 is pressed, that is, switch 602 is active, it indicates that the user wishes to terminate the current action; if the switch is inactive, it indicates that the user has not intervened and the system continues to execute the current action.

[0134] S5: The controller 901 receives the rising current value of the window lifter 501 in real time and compares it with the preset current threshold. If the current value of the current signal does not exceed the preset current threshold, step S6-2 is executed repeatedly; if the current value of the current signal exceeds the preset current threshold, step S6-1 is executed.

[0135] S6-1: The controller 901 determines whether the roof 401 is fully closed. If not, the controller executes step S7-1; if so, the controller executes step S7-3.

[0136] S6-2: The controller 901 determines whether the roof 401 is fully closed. If not, the controller 901 executes step S7-2; if so, the controller 901 continues to execute step S3;

[0137] Among them, S6-1 and S6-2 both involve the judgment of whether the roof 401 is fully closed. This is to ensure that the tailgate glass 502 can determine the height to which it can rise under different conditions (the current value does not exceed the preset current threshold, the current value exceeds the preset current threshold), and thus complete the rising action safely and correctly.

[0138] S7-1: The controller 901 issues a command to control the motor of the tailgate glass lifter 501 to reverse, causing the tailgate glass 502 to descend, and then executes step S8-1;

[0139] S7-2: The controller 901 determines in real time whether the window lifter is at the third soft stop point (i.e., the upper soft stop point in the figure). If so, step S8-2 is executed; if not, step S3 is executed;

[0140] S7-3: The controller 901 determines whether the window lifter 501 is at the upper hard stop point. If so, the controller 901 executes step S8-3; if not, the controller 901 executes step S7-1.

[0141] S8-1: The controller 901 determines whether the window lifter 501 is at the lower hard stop point. If so, the controller 901 executes step S9; if not, the controller 901 executes step S8-1.

[0142] S8-2: The controller 901 issues a command to control the tailgate glass lifter 501 to stop the upward movement, and the process ends;

[0143] S9: The controller 901 sends a command to control the tailgate glass lifter 501 to stop descending, and the process ends.

[0144] and Figure 6 Similarly, this example uses real-time monitoring of the motor's operating status (using current as an indicator) to determine whether to continue the current operation (such as starting or stopping) or to take protective measures (such as backing off). This design not only improves system safety but also effectively protects equipment from damage when potential problems arise.

[0145] The automobile tailgate control method provided in this embodiment controls the tailgate glass to rise by operating a switch with one button, and simultaneously detects and determines the tailgate side unlocking and locking signals, the tailgate lower flip lock locking signals and the roof position signals, so that the tailgate glass rises to the target position.

[0146] Use scenario 4: Back door glass closed and roof closed

[0147] Figure 11 FIG. 1 is a flow chart of a method for controlling the closing of the back door glass and the roof according to an embodiment of the present invention. Figure 11 As shown, the control method for closing the tailgate glass and the roof includes the following steps:

[0148] Step S1101: When a tailgate glass closing and roof closing instruction is received, a roof closing start instruction is issued to drive the roof adjustment device to perform a closing action.

[0149] Step S1102: When the roof reaches the fully closed position, the current status of the tailgate down lock and the tailgate side unlock is obtained.

[0150] Before step S1102, it is also included to determine whether the roof reaches the preset fully closed position.

[0151] Step S1103: When the current states of the tailgate lower flip lock and the tailgate side unlock are both locked, a glass raising start instruction is issued to drive the glass regulating device to perform an ascending action.

[0152] Step S1104: When the back door glass reaches the upper hard stop point, a glass rise stop instruction is issued to drive the glass adjustment device to stop the rising action.

[0153] Before step S1104 , the process also includes determining whether the back door glass has reached a preset upper hard stop point.

[0154] That is to say, the control logic of closing the tailgate glass and the roof is as follows: close the roof, control the tailgate and side doors to be locked after the roof reaches the fully closed position, and then close the tailgate glass.

[0155] Figure 12 1 is a flow chart of an example of a method for controlling the closing of the back door glass and the roof according to an embodiment of the present invention. In this example, long pressing the switch 602 causes the back door glass 502 to rise and the roof 401 to close. Figure 13 Schematic diagram of the roof closing, glass closing, and back door closing according to an embodiment of the present invention. Figure 12 The following steps are involved when the tailgate glass is closed and the roof is closed:

[0156] S1: When the vehicle is unlocked, long press (> preset time) the switch 602, the controller 901 receives the current signal of the switch 602 and executes step S2;

[0157] S2: The controller 901 issues a command to the roof 401 to close. The roof 401 continuously feeds back the motor closing current signal to the controller 901, and then executes step S3.

[0158] S3: The controller 901 determines whether the switch 602 is valid. If not, the controller 901 executes step S4-1; if not, the controller 901 executes step S4-2.

[0159] S4-1: The controller 901 receives the current value of the roof 401 when it is closed in real time and compares it with the preset current threshold. If the current value of the current signal does not exceed the preset current threshold, step S2 is executed repeatedly; if the current value of the current signal exceeds the preset current threshold, step S5 is executed;

[0160] S4-2: The closing action of the roof 401 stops and the process ends.

[0161] S5: The controller 901 determines whether the roof 401 is fully closed. If so, the process proceeds to step S6-1; if not, the process proceeds to step S6-2.

[0162] S6-1: The controller 901 determines the locking signals of the tailgate lower flip lock 203 and the tailgate side unlock 303. If the tailgate lower flip lock 203 and the tailgate side unlock 303 are not all locked, no actuator performs any action and the process ends. If the tailgate lower flip lock 203 and the tailgate side unlock 303 are all locked, step S7 is executed.

[0163] S6-2: The controller 901 issues a command, the motor of the roof 401 reverses, and the motor stops after the roof 401 moves back 100 mm, ending the process;

[0164] S7: The controller 901 issues a command; the glass lifter 501 performs the glass raising action, and the glass lifter 501 continuously feeds back the motor raising current signal to the controller 901, and then executes step S8;

[0165] S8: The controller 901 receives the rising current value of the window lifter 501 in real time and compares it with the preset current threshold. If the current value of the current signal does not exceed the preset current threshold, step S7 is executed repeatedly; if the current value of the current signal exceeds the preset current threshold, step S9 is executed.

[0166] S9: The controller 901 determines whether the position of the back door glass satisfies the upper hard stop point. If not, the controller executes step S10-1; if so, the controller executes step S10-2.

[0167] S10-1: The controller 901 sends a command to control the motor of the tailgate glass lifter 501 to reverse, and the tailgate glass 502 is lowered, and step S11 is executed;

[0168] S10-2: The controller 901 issues a command to control the tailgate glass lifter 501 to stop the upward movement, and the process ends;

[0169] S11: The controller 901 sends a command to control the tailgate glass lifter 501 to stop descending, and the process ends.

[0170] The car tailgate control method provided in this embodiment controls the roof to be closed by operating a switch with one click, and simultaneously detects and determines the tailgate side unlocking and locking signals and the tailgate lower flip lock locking signals to control the tailgate glass to rise, thereby realizing one-click closing of the roof and tailgate glass.

[0175] Specifically, determining the current side door instruction according to the side door opening and closing instruction includes: acquiring a current state of the side door; and determining the current side door instruction according to the side door opening and closing instruction and the current state of the side door.

[0176] Step S1403: When the current instruction of the side door is to open the side door, obtain the current state of the back door side unlocking; when the current state of the back door side unlocking is the locked state, issue a glass rising start instruction to drive the glass adjustment device to perform the rising action; when the back door glass rises to the preset fourth soft stop point, control the back door side unlocking to be in the unlocked state; issue a side door opening start instruction to drive the back door side opening adjustment device to perform the opening action, and when the side door is at the preset fifth soft stop point, issue a side door opening stop instruction to drive the back door side opening adjustment device to stop the opening action, and record the current state of the side door.

[0177] The fourth soft stop point of the back door glass may be located at the same position as the third soft stop point of the back door glass and the first soft stop point of the back door glass. Step S1404: When the current instruction for the side door is to close the side door, a side door closing start instruction is issued to drive the back door side opening adjustment device to perform a closing action. When the current state of the back door side unlocking is the locked state, a side door closing stop instruction is issued to drive the back door side opening adjustment device to stop the closing action, and the current state of the side door is recorded.
