[0057] In the description of this specification, specific features, structures, materials, or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0058] For the double strut electric tailgate control device in the prior art, as Figure 2 shown, the driving and acquisition of its left and right electric struts are completed by the same controller (central controller). Since the left and right electric struts are respectively arranged on the left and right sides of the vehicle, the driving harness of the controller needs to be connected to the left and right sides of the vehicle, and the harness is relatively long and the cost is relatively high; the driving and acquisition of its tailgate lock and the driving and acquisition of the tailgate switch are both connected to the central controller, and the harnesses are numerous and long, and the cost is relatively high. Its harness needs to pass from the body side panel through the tailgate hinge to the tailgate, and the tailgate hinge is a moving part, so the wiring difficulty is increased and the difficulty of preventing the harness from being folded and damaged is increased.

[0059] In some embodiments, as Figure 1 shown, a driving member control method includes:

[0060] Controlling a first driving member to send driving data to a second driving member;

[0061] At a first time, controlling the first driving member to start driving a driven member according to the driving data; and

[0062] Controlling the second driving member to start driving the driven member according to the driving data when receiving the driving data;

[0063] Wherein, the first time is the time from when the first driving member starts to send the driving data to when the second driving member receives the driving data and starts to drive according to the driving data.

[0064] The driving member control method provided by the embodiments of the present disclosure realizes the synchronous control of the two driving members by delaying the start of driving of the first driving member by the first time and starting the driving of the second driving member after receiving the driving data, which is beneficial to improving the motion stability of the driven member.

[0065] Through the above control method, the embodiments of the present disclosure can achieve control mainly by the first driving member, that is, the first driving member can obtain the required driving data according to some control parameters and send the driving data to the second driving member, and the second driving member does not need to obtain the required driving data according to some control parameters anymore. This can effectively ensure the control consistency of the two driving members and avoid some inconsistent control situations caused by parameter acquisition and the like.

[0066] During this process, in order to improve the motion stability of the driven member and prevent the driving forces of the two driving members from being asynchronous, etc., the driving member control method provided by the embodiments of the present disclosure proposes a method that can make the driving member control synchronous. By setting a first time, the driven member starts to be driven after a delay of the first time from when the first driving member sends the driving data, while the second driving member starts to drive the driven member immediately upon receiving the driving data, thereby realizing the synchronous control of the two driving members.

[0067] When the embodiments of the present disclosure control the driven member to reach the required position or state, the driving can be controlled to stop. In order to achieve the control synchronism of stopping the driving and improve the motion stability of the driven member. In some embodiments, the method further includes:

[0068] Controlling the first driving member to send a stop driving signal to the second driving member;

[0069] At the first time, controlling the first driving member to stop driving the driven member; and

[0070] Controlling the second driving member to stop driving the driven member when receiving the stop driving signal.

[0071] That is, the driving member control method provided by the embodiments of the present disclosure realizes the control synchronism throughout the whole process of starting driving, driving process, and stopping driving, effectively improving the motion stability of the driven member.

[0072] In order to prevent situations such as accidental stop of driving caused by abnormal situations such as parameter acquisition, in some embodiments, the method further includes:

[0073] Controlling the first driving member to send the state data of the driven member detected to the second driving member.

[0074] That is, the first driving member can send the state data of the driven member detected to the second driving member as a backup. When data detection of the first driving member is abnormal, the control can be switched in time to ensure the continuity of driving, thereby improving the safety of the driven member.

[0075] Further, in some embodiments, the method further includes:

[0076] When the first driving member is in a state where the status data detection is abnormal, control the second driving member to send driving data to the first driving member;

[0077] At the second time, control the second driving member to start driving the driven member according to the driving data; and

[0078] Control the first driving member to start driving the driven member according to the driving data when receiving the driving data;

[0079] Wherein, the second time is the time from when the second driving member starts to send the driving data to when the first driving member receives the driving data and starts to drive according to the driving data.

[0080] For the driving member control method provided by the embodiments of the present disclosure, when the first driving member has an abnormal data detection situation, the second driving member can be controlled to send driving data to the first driving member, that is, the driving switching between the two driving members is realized, thereby effectively ensuring the control continuity of the driven member.

[0081] In order to ensure the control synchronization of the two driving members, the driving member control method provided by the embodiments of the present disclosure sets a second time. The second driving member starts to drive the driven member after delaying for the second time when sending the driving data, and the first driving member starts to drive the driven member as soon as it receives the driving data, thereby realizing the synchronous control of the two driving members.

[0082] In some embodiments, when the first driving member is in a state where the status data detection is abnormal, controlling the second driving member to send driving data to the first driving member includes: when the second driving member determines that the first driving member is in a state where the status data detection is abnormal, controlling the second driving member to send driving data to the first driving member.

[0083] For whether the first driving member is in a state where the status data detection is abnormal, those skilled in the art can make a judgment through various appropriate methods.

[0084] In some embodiments, the second driving member determining that the first driving member is in a state where the status data detection is abnormal includes: the second driving member determining that the first driving member is in a state where the status data detection is abnormal according to the detection abnormal signal sent by the first driving member.

[0085] That is, when the first driving member has a detection abnormality, it can send the detection abnormal signal to the second driving member. When the second driving member receives the detection abnormal signal sent by the first driving member, it can drive the first driving member to be in a state where the status data detection is abnormal, so as to start taking over the driving control of the first driving member.

[0086] In some embodiments, the situation where the second driving member determines that the first driving member has an abnormal status data detection includes: when the second driving member does not receive a stop driving signal and does not receive status data at the third time, the second driving member determines that the first driving member has an abnormal status data detection.

[0087] In some embodiments, the first driving member may not need to send a detection abnormal signal, and the second driving member can make a judgment based on some information, that is, when the second driving member does not receive a stop driving signal and does not receive status data at the third time, it can be determined that the first driving member has an abnormal status data detection.

[0088] In normal situations, the first driving member continuously sends the detected status data, and the second driving member also continuously receives this status data. If the status data is not received within a certain time after the previous reception of this status data, and at the same time, the stop driving signal is not received, it can be determined that the first driving member has an abnormal status data detection.

[0089] At the same time, this method can also be applied to the situation where the first driving member has normal detection but may have a communication failure.

[0090] When the first driving member has an abnormal status data detection, in order to switch the control in time to ensure control continuity, in some embodiments, the third time is the time from when the first driving member starts to send status data to when the second driving member receives the status data.

[0091] In some embodiments, controlling the second driving member to send driving data to the first driving member includes: controlling the second driving member to send the driving data determined according to the last received status data to the first driving member.

[0092] Before the first driving member has an abnormal status data detection, the first driving member determines the driving data according to the detected parameters. In order to ensure the timeliness of control, when the first driving member has an abnormal status data detection, the second driving member determines the driving data according to the last received status data, thus ensuring the timeliness and continuity of control.

[0093] After the second driving member takes over the control, in some embodiments, the method further includes:

[0094] Controlling the second driving member to send the detected status data of the driven member to the first driving member.

[0095] That is, the second driving member sends the detected status data to the first driving member for backup. If the second driving member has an abnormal detection situation, the first driving member can take over the control in time, especially when the first driving member resumes normal detection.

[0096] In some embodiments, controlling the first driving member to send driving data to the second driving member includes: when receiving a start driving signal, controlling the first driving member to send the driving data to the second driving member.

[0097] In some embodiments, when receiving a start driving signal, controlling the first driving member to send driving data to the second driving member includes: when the driven member is unlocked, sending a start driving signal to the first driving member, and when receiving the start driving signal, controlling the first driving member to send the driving data to the second driving member.

[0098] In some embodiments, when the driven member needs to perform an action after being unlocked, there can be various suitable ways to start the driving process. For example, sending a start driving signal to the first driving member, and after the first driving member receives the start driving signal, the first driving member can be controlled to start driving.

[0099] The driven member can be unlocked in various suitable ways. In some embodiments, unlocking the driven member includes: when the locking member receives a switch signal and determines that the driven member can be opened, controlling the locking member to unlock the driven member.

[0100] In the initial state, the driven member is locked by the locking member. When the locking member receives the switch signal, it can determine whether the opening condition of the driven member is satisfied. When the opening condition is satisfied, the locking member is controlled to unlock. After the driven member is unlocked, a start driving signal can be sent to the first driving member, and then the driven member can be driven to move, so as to meet the control requirements of the driven member.

[0101] In order to better ensure the driving consistency of the driven member and make the driving synchronization of the two driving members better, in some embodiments, before controlling the first driving member to send driving data to the second driving member, the method includes: controlling the first driving member and the second driving member to perform time calibration.

[0102] Those skilled in the art can adopt various suitable ways to control the first driving member and the second driving member to perform time calibration. In some embodiments, a clock synchronization signal can be sent to the first driving member and the second driving member, and after the first driving member and the second driving member receive the clock synchronization signal, they can perform time calibration.

[0103] The driving member control method provided by the embodiments of the present disclosure realizes the synchronous control of the two driving members by delaying the start of driving of the first driving member by a first time and starting driving after the second driving member receives the driving data, which is beneficial to improving the movement stability of the driven member.

[0104] The present disclosure also provides a driving member control system, including:

[0105] The first control unit is configured to control the first driving member to send driving data to the second driving member; and at a first time, control the first driving member to start driving the driven member according to the driving data; and

[0106] The second control unit is configured to control the second driving member to start driving the driven member according to the driving data when receiving the driving data;

[0107] Wherein, the first time is the time from when the first driving member starts to send the driving data to when the second driving member receives the driving data and starts to drive according to the driving data.

[0108] In the driving member control system provided by the embodiments of the present disclosure, by delaying the first driving member to start driving for the first time and the second driving member to start driving after receiving the driving data, synchronous control of the two driving members is achieved, which is beneficial to improving the motion stability of the driven member.

[0109] The present disclosure also provides a driving member control system, including: a memory for storing a computer program; a processor for executing the computer program stored in the memory, so that the device executes the above method.

[0110] The present disclosure also provides a computer-readable storage medium, on which a computer program is stored. When the computer program is executed by a computer, the above method is implemented.

[0111] The present disclosure also provides a vehicle, including: the above driving member control system.

[0112] The driven member and the driving member can be various suitable components. In some embodiments, the driven member is: an electric tailgate, a soft top convertible, or an electric front hood; the first driving member is a first motor, and the second driving member is a second motor. For example, the driven member can be an electric tailgate, the first driving member is a first motor (left strut motor), and the second driving member is a second motor (right strut motor).

[0113] The vehicle has the same structure and beneficial effects as any of the above embodiments, which will not be elaborated here.

[0114] Next, taking the driven member as an electric tailgate, the first driving member as the left strut motor, and the second driving member as the right strut motor as an example for illustration.

[0115] In the prior art, the double-strut electric tailgate control device, such as Figure 2 As shown, wherein, the left strut motor, the right strut motor, the tailgate lock, and the tailgate switch are all connected to the central controller, and the central controller is responsible for their driving and acquisition. The wiring harness is long and numerous, and the cost is high.

[0116] In some embodiments, the present disclosure provides an electric tailgate control device, as Figure 3 shown, including:

[0117] A left strut motor, a central controller, a right strut motor, a tailgate lock, and a tailgate switch. The left strut motor and the right strut motor are built-in with control units, which can realize the driving and signal acquisition of the motors. The left strut motor and the right strut motor are connected to the central controller through communication lines; the tailgate lock is built-in with a control unit, which can realize the driving and signal acquisition of the lock and is connected to the central controller through a communication line; the driving and signal acquisition of the tailgate switch are connected to the tailgate lock, and the driving and signal acquisition of the tailgate switch are realized by the control unit built in the tailgate lock.

[0118] For this electric tailgate control device, the left strut motor and the right strut motor are built-in with control units, which can realize the driving and signal acquisition of the motors and are connected to the central controller through communication lines, reducing the connection wire harness with the central controller compared with the prior art; the tailgate lock is built-in with a control unit, which can realize the driving and signal acquisition of the lock and can also realize the driving and signal acquisition of the tailgate switch, and is connected to the central controller through a communication line, reducing the connection wire harness with the central controller compared with the prior art, thereby achieving the purpose of reducing the wire harness and saving costs.

[0119] To solve the problem of the synchronization of the left and right struts controlled by different control units, the present disclosure provides a synchronous control method for the left strut motor control unit and the right strut motor, and the method is as follows:

[0120] As Figure 4 shown, the central controller simultaneously sends clock synchronization signals to the left strut motor and the right strut motor according to the set time period. The left strut motor and the right strut motor receive the synchronization signals and calibrate their respective clocks, thereby ensuring the clock synchronization of the left strut motor and the right strut motor.

[0121] One of the left strut motor and the right strut motor is set as the main control module, and the other is set as the slave control module. For example, the left strut motor is set as the main control module and the right strut motor is set as the slave control module; according to the control link and communication period, the time from when the left strut motor starts to send an instruction to when the right strut motor receives the instruction and starts to execute the action is set as T1; as Figure 5As shown, the rear door lock collects the signal of the rear door switch, sends the switch signal to the central controller through the communication line. After logical calculation by the central controller, when it judges that the condition for opening the rear door is met, it sends an opening instruction to the left strut motor. The left strut motor calculates the duty cycle required to drive the rear door according to the current position of the rear door and the signal status (such as Hall signal, current signal, etc.) collected in real time, sends the duty cycle to the right strut motor and starts timing at the same time. When the timing reaches time T1, the left strut motor starts to drive the motor according to the calculated duty cycle. The right strut motor receives the duty cycle signal and immediately drives the motor to act, thus ensuring the synchronization of the left strut motor and the right strut motor in driving the motor and ensuring the smoothness of the rear door movement. The control timing is as Figure 6 shown.

[0122] The present disclosure also provides a method for mutual calibration and redundant control of the positions of the left strut motor and the right strut motor as follows:

[0123] One of the left strut motor and the right strut motor is set as the main control module, and the other is set as the slave control module. For example, the left strut motor is used as the main control module and the right strut motor is used as the slave control module; the left strut motor collects the position signal, after position calculation, sends it to the right strut motor in real time. The right strut motor updates the position status according to the received position signal according to the set time period T2; when the position signal collected by the left strut motor is abnormal, the right strut motor serves as the main control module and the left strut motor serves as the slave control module, and controls the rear door according to the synchronous control method described above. The time period T2 can be the communication period between the left strut motor and the right strut motor.

[0124] The electric rear door control method provided by the embodiment of the present disclosure is as follows: when the rear door is in the fully closed state, press the rear door switch. The rear door lock detects the switch signal, sends the switch signal to the central controller through the communication line. The central controller judges the rear door opening condition. When the opening condition is met, the central controller sends an unlocking instruction to the rear door lock. The rear door lock receives the unlocking instruction, executes the unlocking drive, and collects the rear door lock status signal and feeds it back to the central controller in real time; the central controller collects the signal that the rear door lock changes from locked to unlocked, sends a strut opening action instruction to the left strut motor. The left strut motor sends the preset duty ratio value to the right strut motor and starts timing T1. When the timing reaches T1, it starts to drive the left strut motor. The right strut motor immediately drives the right strut motor when it receives the duty cycle; during the operation of the left strut motor, it calculates the duty cycle required to drive the strut according to the collected signal in real time and sends it to the right strut motor, and cycles according to the above synchronous method until the left strut motor judges that the rear door opening position reaches the preset position and then sends a stop instruction to the right strut motor, and stops driving after timing T1. The right strut motor immediately stops driving when it receives the stop instruction.

[0125] The electric tailgate and control method provided by the embodiments of the present disclosure have the following advantages:

[0126] 1) The length, cost, and weight of the wire harness are reduced; 2) The existing domain controllers of the whole vehicle can be used without adding domain controllers in the tailgate area, reducing the number of domain controllers, the weight of the whole vehicle, and the cost of the whole vehicle; 3) The wire harness connecting the tailgate and the side body only has a power line and a communication line, with a small wire diameter. The wire harness is easy to arrange and hide.
