Description

Technical Field

[0001] This invention relates to the field of vehicle tailgate control technology, and particularly to a tailgate control method. Furthermore, this invention also relates to a tailgate control device and storage medium capable of implementing the tailgate control method, and a vehicle equipped with the tailgate control device. Background Technology

[0002] An electric tow hook is an accessory used on vehicles for towing RVs, trucks, or for off-road rescue. It is usually installed at the rear of the vehicle, at the same height as or slightly lower than the bumper, and can be folded and hidden inside the vehicle bumper according to the operating instructions.

[0003] Power tailgates with hands-free operation are a common feature in modern vehicles, allowing owners to easily open or close the trunk lid electrically or remotely. Typically, power tailgates use an antenna to detect foot kicks near the rear bumper, controlling the opening and closing of the tailgate.

[0004] However, for vehicles with both an electric tow hook and an electric sensor-operated tailgate, there is a malfunction where the tailgate opens incorrectly when the electric tow hook is activated. The main reason is that in existing control methods, the sensor antenna sends a signal to the controller whenever it detects a moving object. If the electric sensor-operated tailgate is controlled based on this signal, it can easily lead to the tailgate opening erroneously. Summary of the Invention

[0005] In view of this, the present invention aims to provide a control method for the tailgate to prevent accidental opening of the tailgate and improve the user's driving experience.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A method for controlling a tailgate, applied to a vehicle equipped with an electric trailer hitch and an electric sensor-operated tailgate, the method comprising:

[0008] When the electric trailer hitch is triggered, the operating information of the electric trailer hitch is acquired;

[0009] If the acquired operating information includes preset operating information, the electric sensor tailgate shall be prohibited from being opened;

[0010] The preset operating information includes at least a first preset information requesting that the electric trailer hook be in operation, and a second preset information that the trailer hook of the electric trailer hook is in operation.

[0011] Furthermore, when the electric trailer hitch is triggered, acquiring the operating information of the electric trailer hitch includes:

[0012] The first controller obtains the trigger information from the electric trailer module and controls the electric trailer hook to start running;

[0013] During the operation of the electric trailer hook, the electric trailer module acquires the operating information of the electric trailer hook and sends it to the first controller;

[0014] The operation information of the electric trailer hitch includes first information requesting that the electric trailer hitch be in operation, and second information indicating that the trailer hitch of the electric trailer hitch is in operation.

[0015] Furthermore, the step of preventing the electric sensor tailgate from being opened when the acquired operating information includes preset operating information includes:

[0016] The tailgate sensor opening controller obtains the operating information through the first controller. If the obtained operating information includes the preset operating information, the tailgate sensor opening controller does not send a tailgate opening signal to the first controller.

[0017] Furthermore, obtaining the operating information of the electric trailer hook also includes the rear door sensor opening controller acquiring the current capacitance parameters generated by the sensor antenna in real time.

[0018] The method for determining that the acquired operating information includes the second preset information that the trailer hitch is in operation includes: if the change curve of the acquired capacitor parameter formed by the change of the capacitor parameter in the first time period is the same as the change of the preset capacitor parameter, the tailgate sensor opening controller determines that the acquired operating information includes the second preset information that the trailer hitch is in operation.

[0019] Furthermore, if the acquired operating information does not include the preset operating information, the control method further includes:

[0020] Detect the sensor action signal used to open the electric sensor tailgate;

[0021] If the detected sensing action signal is a preset sensing action signal, the tailgate sensor opening controller sends a tailgate opening signal to the first controller.

[0022] The first controller controls the tailgate lock to open the electric sensor tailgate via the tailgate controller.

[0023] Furthermore, the control method also includes:

[0024] Obtain the vehicle speed signal;

[0025] If the acquired vehicle speed signal is below a preset speed threshold, the opening of the electric sensor-operated tailgate is permitted; and if the acquired operating information does not include the preset operating information, the electric sensor-operated tailgate is permitted to be opened.

[0026] Compared with the prior art, the present invention has the following advantages:

[0027] The tailgate control method described in this invention can prevent the tailgate from opening when the electric trailer hitch is triggered, based on first information requesting the electric trailer hitch to be in operation or second information requesting the trailer hitch to be in operation. This effectively prevents the tailgate from opening accidentally during trailer hitch operation without requiring additional hardware configuration. This allows the electric trailer hitch and electric tailgate functions to be integrated into the vehicle without affecting each other, thus improving the user experience for drivers and passengers.

[0028] Another objective of this invention is to provide a control device for a tailgate, applicable to vehicles equipped with an electric trailer hitch and an electric sensor tailgate, the control device comprising an acquisition module and a control module;

[0029] The acquisition module is used to acquire the operating information of the electric trailer hook when the electric trailer hook is triggered to operate;

[0030] The control module is used to prevent the electric sensor tailgate from being opened when the acquired operating information includes preset operating information.

[0031] The preset operating information includes at least a first message requesting that the electric trailer hitch be in operation, and a second message that the trailer hitch of the electric trailer hitch is in operation.

[0032] Furthermore, the acquisition module is an electric trailer module connected to the electric trailer hook, and the control module is a body domain controller connected to the electric trailer module and the tailgate sensor opening controller.

[0033] Furthermore, another object of the present invention is to provide a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, enables the control method for the rear door as described above.

[0034] Another object of the present invention is to provide a vehicle in which a control device for the tailgate as described above is provided.

[0035] The tailgate control device, computer-readable storage medium, and vehicle described in this invention have the same beneficial effects as the aforementioned tailgate control method compared to the prior art, and will not be repeated here. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention in light of the specific circumstances.

[0045] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Example 1

[0047] This embodiment relates to a control method for a tailgate, which is applicable to vehicles that are equipped with both an electric tow hook 1 and an electric sensor tailgate. This method is a novel way to shield the operation of the electric tow hook 1 from the electric sensor tailgate. In cases where the electric tow hook 1 has inaccurate mechanical manufacturing precision and operation timing, this method can ensure the normal shielding of the deployment and retraction of the electric tow hook 1, thus preventing the tailgate from being opened accidentally.

[0048] Based on the above design concept, an exemplary structure of the rear door control method in this embodiment is as follows: Figure 1 As shown, it mainly includes the following steps.

[0049] S101. When the electric trailer hook 1 is triggered to run, obtain the running information of the electric trailer hook 1.

[0050] This step is performed by the following acquisition module, in conjunction with... Figure 3 As shown, preferably, the acquisition module can be, for example, an electric trailer module 4. The operating information of the electric trailer hook 1 can be acquired by the electric trailer module 4, and the electric trailer module 4 sends the acquired operating information of the electric trailer hook 1 to the control module described below.

[0051] It should be noted that, in this embodiment, the operation process after the electric trailer hook 1 is triggered includes the operation process of the trailer hook deployment process of the electric trailer hook 1, as well as the operation process of the trailer hook retraction process.

[0052] Furthermore, the operating information of the electric trailer hook 1 includes a first message requesting that the electric trailer hook 1 be in an operating state, and a second message indicating that the trailer hook of the electric trailer hook 1 is in operation. Specifically, the first message is issued by the electric trailer hook operation switch 5 described below, and the first message requesting that the electric trailer hook 1 be in an operating state includes a message requesting that the trailer hook be deployed, as well as a message requesting that the trailer hook be retracted.

[0053] S102. If the acquired operating information includes preset operating information, the electric sensor tailgate shall be prohibited from being opened; wherein, the preset operating information includes at least a first preset information that the electric trailer hook 1 is in an unlocked state, and a second preset information that the trailer hook of the electric trailer hook 1 is in motion.

[0054] During the process of the electric sensor tailgate shielding the electric trailer hook 1, there is a time and mechanical structure precision error between the time the electric trailer hook 1 starts executing the command and the time the electric trailer hook 1 actually starts rotating to execute the command. Therefore, the following problem exists: after the electric sensor tailgate starts shielding the electric trailer hook 1, the electric trailer hook 1 has not yet moved. The electric trailer hook 1 only starts moving after the electric sensor tailgate completes the shielding action procedure.

[0055] Therefore, in order to prevent the erroneous situation where the trailer hitch action triggers the opening of the electric sensor-operated tailgate, the preset operating information in this embodiment includes at least a first preset information requesting that the electric trailer hitch 1 is in operation, and a second preset information that the trailer hitch of the electric trailer hitch 1 is in operation. When the obtained operating information includes at least one of the first preset information and the second preset information, the electric sensor-operated tailgate is prohibited from being opened, which has a good beneficial effect of avoiding the accidental opening of the tailgate.

[0056] In this step, the first preset information for requesting the electric trailer hook 1 to be in operation includes preset information for requesting the trailer hook to deploy and preset information for requesting the trailer hook to retract.

[0057] It should be noted that step S102 is executed by the control module described below. The control module may be, for example, the body domain controller 7 connected to the electric trailer module 4 and the tailgate sensor opening controller (HFA) 6. When the body domain controller 7 receives the preset information, the tailgate sensor opening controller 6 prohibits the body domain controller 7 from sending a signal to request the opening of the tailgate. Naturally, the body domain controller 7 will not control the opening of the tailgate, which can improve the reliability of preventing the tailgate from being opened accidentally.

[0058] In a preferred embodiment, the second preset information mentioned in step S102 is preferably a signal that the trailer hook 1 is in the process of being deployed. Based on the signal that the trailer hook 1 is in the process of being deployed, the opening of the electric induction tailgate is prohibited, which has a good effect in preventing the tailgate from being opened accidentally. However, the second preset information can be a signal that the trailer hook is in the process of being deployed, or it can be a signal that the trailer hook is in the process of being retracted.

[0059] Specifically, the aforementioned second information, namely the signal that the trailer hook is in motion, can be obtained by the electric trailer module 4 from the trailer hook drive device of the electric trailer hook 1. Generally, the trailer hook drive device is usually a drive motor.

[0060] In this embodiment, for example, detecting the drive current of the drive motor or detecting whether the power output terminal of the drive motor is activated can determine whether the drive motor is in operation. The specific detection method can refer to the existing method. When it is detected that the drive motor is in operation, the second information is sent to the electric trailer module 4. The electric trailer module 4 will send the second information to the body domain controller 7. When the body domain controller 7 receives the second information, if the second information is the same as the second preset information, it will prevent the electric sensor tailgate from being opened, that is, it will not send the control command to control the electric sensor tailgate to open.

[0061] It should also be noted that in this embodiment, preventing the electric sensor tailgate from being opened includes not only preventing the tailgate lock 9 from unlocking, but also preventing the tailgate drive device from operating, so as to prevent the tailgate from being opened.

[0062] In the aforementioned step S101, when the electric trailer hook 1 is triggered to run, the running information of the electric trailer hook 1 is obtained, including the first controller obtaining the trigger information of the electric trailer module 4 and controlling the electric trailer hook 1 to start running. During the operation of the electric trailer hook 1, the running information of the electric trailer hook 1 is obtained through the electric trailer module 4 and sent to the first controller.

[0063] In this embodiment, the first controller is preferably the existing vehicle body domain controller 7. The vehicle body domain controller 7 obtains the trigger information of the electric trailer module 4 and controls the electric trailer hook 1 to start operating. During the operation of the electric trailer hook 1, the electric trailer module 4 obtains the operating information of the electric trailer hook 1 and sends it to the vehicle body domain controller 7. It should be understood that the first controller can be the vehicle body domain controller 7, or it can be another separately set controller, or other existing controllers on the vehicle.

[0064] Specifically, in this embodiment, the vehicle body domain controller 7 is triggered by manipulating the electric trailer hook operation switch 5, and the vehicle body domain controller 7 controls the operation of the electric trailer hook 1 through the electric trailer module 4. Referring again... Figure 3 As shown, when the driver or passenger operates the electric trailer hitch operation switch 5, the request signal is the first information indicating that the electric trailer hitch 1 is in the unlocked state. The first information is sent to the body domain controller 7 via the electric trailer hitch operation switch 5. If the body domain controller 7 receives the first information, and the first information is the same as the first preset information, it will prevent the electric sensor tailgate from opening.

[0065] In the aforementioned step S102, if the acquired operating information includes preset operating information, the electric induction tailgate is prohibited from being opened. This includes the tailgate induction opening controller 6 acquiring operating information through the first controller. If the acquired operating information includes preset operating information, the tailgate induction opening controller 6 does not send a tailgate opening signal to the first controller.

[0066] In this embodiment, the first controller is still the vehicle body domain controller 7 as an example. The tailgate sensor opening controller 6 obtains preset operating information through the vehicle body domain controller 7. If the obtained operating information contains the preset operating information, it does not send a tailgate opening signal to the vehicle body domain controller 7. If the vehicle body domain controller 7 does not receive a tailgate opening signal, it prohibits the electric sensor tailgate from being opened.

[0067] It should be noted that, in this embodiment, the tailgate sensor opening controller 6 specifically obtains the operating information of the electric trailer hitch 1 through the vehicle domain controller 7. Specifically, the operating information of the electric trailer hitch 1 includes the aforementioned first information and second information. The first information is sent to the vehicle domain controller 7 by the electric trailer hitch operation switch 5, while the second information is obtained by the electric trailer module 4 from the electric trailer hitch 1 and sent to the vehicle domain controller 7. The tailgate sensor opening controller 6 can obtain the first information and the second information from the vehicle domain controller 7.

[0068] More specifically, the tailgate sensor opening controller 6 does not send a tailgate opening signal to the body domain controller 7 after obtaining the first information and the second information. In other words, even if the tailgate sensor opening controller 6 senses a kicking action, it will not send a tailgate opening signal to the body domain controller 7, which helps to improve the reliability of preventing the tailgate from being opened accidentally.

[0069] In this embodiment, the tailgate sensor opening controller 6 obtains preset operating information through the vehicle body domain controller 7, which facilitates the arrangement of the tailgate control device described below on the vehicle.

[0070] When the acquired operating information includes preset operating information, the tailgate sensor controller 6 will not send a tailgate opening signal to the body domain controller 7. This setting allows for control at the source, effectively preventing accidental tailgate opening. Furthermore, since neither the tailgate sensor controller 6 nor the body domain controller 7 sends a tailgate opening signal, the reliability of preventing accidental tailgate opening is high.

[0071] It should also be noted that in this embodiment, the tailgate sensor opening controller 6 obtaining operating information through the vehicle domain controller 7 is only a preferred implementation. In addition, the tailgate sensor opening controller 6 can of course also obtain operating information from the electric trailer module 4.

[0072] In a preferred embodiment, if the operating information acquired by the tailgate sensor opening controller 6 does not include preset operating information, the control method further includes detecting a sensor action signal for opening the electric sensor tailgate. If the detected sensor action signal is a preset sensor action signal, the tailgate sensor opening controller 6 sends a tailgate opening signal to the first controller, and the first controller controls the tailgate lock 9 to open the electric sensor tailgate through the tailgate controller 8.

[0073] It should be noted that the first controller here is preferably the existing body domain controller 7 on the vehicle. It should be understood that, in addition to this, it may also be other existing controllers or newly added controllers on the vehicle.

[0074] Combination Figure 3 As shown in this embodiment, the tailgate sensor opening controller 6 is specifically connected to the sensing antenna 2. The sensing antenna 2 is, for example, a mobile object sensor installed at the rear of the vehicle, which is arranged below the rear bumper. When the mobile object sensor detects a kicking action, it will send a signal to the tailgate sensor opening controller 6. If the tailgate sensor opening controller 6 does not receive the preset information, it will send a signal to open the tailgate.

[0075] Specifically, the body domain controller 7 is connected to the tailgate controller 8, and the tailgate controller 8 is connected to the tailgate lock 9. When the body domain controller 7 receives the tailgate opening signal from the tailgate sensor opening controller 6, the body domain controller 7 sends a tailgate opening command to the tailgate controller 8, which then controls the tailgate lock 9 to unlock. This can be done without changing the existing structure or modifying the vehicle structure, thus reducing costs.

[0076] To improve the reliability of preventing accidental opening of the tailgate, as a preferred embodiment, obtaining the operating information of the electric trailer hook 1 also includes the tailgate sensor opening controller 6 acquiring the current capacitance parameters generated by the sensor antenna 2 in real time.

[0077] The method for determining that the acquired operating information includes the second preset information that the trailer hook is in operation includes: if the capacitor parameter change curve formed by the change of the acquired capacitor parameter in the first time period is the same as the preset capacitor parameter change curve, the tailgate sensor opening controller 6 determines that the acquired operating information includes the second preset information that the trailer hook is in operation.

[0078] It should be understood that determining whether the capacitance parameter change curve formed by the change of the capacitance parameter of the acquired induction antenna 2 in the first time is the same as the preset capacitance parameter change curve is mainly used to determine whether the capacitance change is caused by the operation of the trailer hook or by human foot movement. This judgment process can accurately distinguish the capacitance change of the induction antenna 2 caused by the operation of the trailer hook. Thus, if it is determined that the operation of the trailer hook causes the capacitance change of the induction antenna 2, the electric induction tailgate should be prohibited from being opened, which can improve the reliability of preventing the tailgate from being opened accidentally.

[0079] It should be noted that, in this embodiment, the arrangement of the induction antenna 2 can be referred to the structure in the prior art. Generally speaking, there are two induction antennas 2. For ease of description, in this embodiment, these two induction antennas 2 are referred to as the first induction antenna and the second induction antenna. Both the first induction antenna and the second induction antenna extend along the left and right direction of the vehicle, and the first induction antenna and the second induction antenna are arranged in parallel and at intervals.

[0080] It should be understood that the capacitance of the first and second sensing antennas will change during both the deployment and retraction of the trailer hitch. Furthermore, the capacitance of both the first and second sensing antennas will also change when a person shakes their foot behind the vehicle. Therefore, the existing sensing antenna 2 cannot distinguish whether the trailer hitch is moving or a person's foot is shaking behind the vehicle. As a result, the rear door may be accidentally opened during the deployment or retraction of the trailer hitch.

[0081] However, the inventors discovered through careful study that the position of the trailer hook and the speed of its deployment or retraction are fixed. Therefore, in this embodiment, a capacitor is used to determine whether the trailer hook is in motion, thereby distinguishing between the movement of the trailer hook and the movement of a person's feet. This can prevent the rear door from being opened accidentally during the operation of the trailer hook, and the functions of electrically deploying and retracting the trailer hook and controlling the opening of the rear door with the induction antenna 2 can be integrated into the same vehicle.

[0082] More specifically, the deployment or retraction of the electric trailer hook occurs within a certain time period. For ease of description, in this embodiment, the time required for the deployment or retraction of the electric trailer hook is referred to as the second time. It should be understood that during the deployment or retraction of the electric trailer hook, the capacitance changes of the first and second sensing antennas follow the same pattern within the second time period, and the method for determining whether the acquired operational information includes the second preset information is also the same. Therefore, in this embodiment, the method for determining whether the acquired operational information includes the second preset information during the trailer hook deployment process will be used as an example for explanation.

[0083] When the trailer hitch is not activated (i.e., not in operation), the capacitance of the first and second sensing antennas acquired by the tailgate sensor opening controller 6 remains constant. However, during the trailer hitch deployment process, the capacitance of the first and second sensing antennas changes within a second time period. Therefore, in this embodiment, the capacitance parameter change curves formed by the capacitance changes of the first and second sensing antennas within the second time period are stored to form a first preset capacitance parameter change curve and a second preset capacitance parameter change curve.

[0084] In the actual storage process, the parameters that form the first preset capacitor parameter change curve and the second preset capacitor parameter change curve include, for example, the capacitor parameters at each time point after dividing the second time into multiple time periods, the second time, the interval between the start of change of the capacitance of the first induction antenna and the second induction antenna, and the time when the capacitance is at the peak and trough, etc.

[0085] During the deployment of the trailer hitch, the tailgate sensor opening controller 6 acquires the current capacitance of the first and second sensing antennas in real time. For example, it starts timing when the capacitance of the first and second sensing antennas changes and ends when the capacitance of the first and second sensing antennas returns to the initial capacitance. The time of the capacitance change is also known as the first time.

[0086] The capacitance parameter change curve formed by the change of the capacitance parameter of the first sensing antenna in the first time period is compared with the first preset capacitance parameter change curve, and the capacitance parameter change curve formed by the change of the capacitance parameter of the second sensing antenna in the first time period is compared with the second preset capacitance parameter change curve. For example, the capacitance parameters at each time point, the second time, the interval between the start of change of the capacitance of the first sensing antenna and the second sensing antenna, the time when the capacitance is at the peak and trough, etc., are compared one by one. If the capacitance change pattern is consistent and the interpolation of each parameter value with the preset parameter value does not exceed the corresponding rated difference, then the rear door sensor opening controller 6 can determine that the acquired operating information includes the second preset information that the trailer hook is in operation.

[0087] For example, there is a set rated time difference between the first time when the capacitance changes and the preset second time; there is a set rated time difference between the time interval when the first sensing antenna and the second sensing antenna start to change and the preset time interval; and there is a set rated peak difference between the obtained capacitance peak and the preset capacitance peak.

[0088] It should be noted that the pre-stored capacitance values, time values, rated differences, and other parameters were all determined after detailed calculations based on multiple experiments, and are not specifically limited in this embodiment. The specific parameters to be compared are not specifically limited in this embodiment; however, it should be understood that the more parameters compared, the more reliable the comparison results.

[0089] To improve the safety of opening the tailgate, as a preferred embodiment, the tailgate control method of this embodiment further includes acquiring the vehicle speed signal, allowing the electric induction tailgate to be opened when the acquired vehicle speed signal is below a preset speed threshold, and allowing the electric induction tailgate to be opened when the acquired operating information does not contain preset operating information.

[0090] Specifically, the vehicle speed signal is still obtained by the body domain controller 7, which is connected to the ESP (Electronic Stability Program). The body domain controller 7 can obtain vehicle speed information from the ESP.

[0091] It should be noted that the vehicle speed controller 7 obtaining vehicle speed information from ESP is only an exemplary implementation. In addition to obtaining vehicle speed information from ESP, the vehicle speed controller 7 can also obtain vehicle speed information from other structures. For example, the vehicle speed controller 7 can directly obtain vehicle speed information from the vehicle speed sensor.

[0092] Furthermore, for driving safety considerations, the preset speed threshold in this embodiment can be, for example, 5 km / h. When the vehicle speed is less than or equal to 5 km / h, triggering the opening of the electric tailgate is permitted. It should be understood that the preset speed threshold of 5 km / h is merely an exemplary implementation; the preset speed threshold can, of course, be other values, such as 4 km / h, 6 km / h, etc.

[0093] In addition, the tailgate control method of this embodiment also allows the electrically operated tailgate to be opened even when the acquired operating information does not include preset operating information.

[0094] To better understand the control method for the tailgate in this embodiment, an exemplary flowchart can be referred to. Figure 2 As shown, the main steps include the following:

[0095] S201, Vehicle powered on.

[0096] S202. Determine the state of the electric trailer hook operation switch 5. If the electric trailer hook operation switch 5 is in the open state, proceed to step S203. If the electric trailer hook operation switch 5 is in the closed state, proceed to step S207.

[0097] S203, the electric trailer module 4 sends a first message requesting that the electric trailer hook 1 is in operation, and a second message requesting that the trailer hook of the electric trailer hook 1 is in operation. The first and second messages are sent to the vehicle body domain controller 7.

[0098] S204. The electric tailgate sensor opening controller 6 receives the first information and the second information. Specifically, the tailgate sensor opening controller 6 obtains the first information and the second information from the vehicle body domain controller 7.

[0099] S205. If the first information is the same as the first preset information, or if the second information is the same as the second preset information, the electric induction tailgate opening controller 6 shall prohibit sending the preset tailgate opening signal to the body domain controller 7. With this setting, the body domain controller 7 shall not send the tailgate opening signal to the tailgate control, that is, the body domain controller 7 shall not control the tailgate lock to open the electric induction tailgate through the tailgate controller 8.

[0100] S206. The power tailgate does not operate. Since the power tailgate has not received an opening signal, if the power tailgate was originally locked, it will remain locked to prevent the power tailgate from being opened accidentally.

[0101] S207, Process Ended.

[0102] The tailgate control method of this embodiment can prevent the tailgate from opening when the electric trailer hitch 1 is triggered to open, based on the first preset information that the electric trailer hitch 1 is in operation and the second preset information that the trailer hitch is in motion. This can effectively prevent the tailgate from opening accidentally during the movement of the trailer hitch. No additional hardware configuration is required, so that the electric trailer hitch 1 and the electric tailgate function can be integrated into the vehicle without affecting each other, which is beneficial to improving the driving experience of drivers and passengers.

[0103] Example 2

[0104] This embodiment relates to a control device for a tailgate, applied to a vehicle equipped with an electric trailer hitch 1 and an electric sensor-operated tailgate, such as... Figure 3 As shown, the control device for the rear door in this embodiment includes an acquisition module and a control module, which are connected together.

[0105] Specifically, the acquisition module in this embodiment is used to acquire the operation information of the electric trailer hook 1 when the electric trailer hook 1 is triggered to operate, and the aforementioned control module is used to prevent the electric sensor tailgate from being opened when the acquired operation information includes preset operation information. The preset operation information includes at least a first preset information requesting that the electric trailer hook 1 be in operation, and a second preset information that the trailer hook of the electric trailer hook 1 is in operation.

[0106] In a preferred embodiment, the first information indicating that the electric trailer hook 1 is in an unlocked state comes from the electric trailer hook operation switch 5, while the second information indicating that the trailer hook of the electric trailer hook 1 is in motion comes from the trailer hook drive device of the electric trailer hook 1.

[0107] In this embodiment, the second information is preferably a signal that the trailer hook of the electric trailer hook 1 is in the process of unfolding. In addition, it can also be a signal that the trailer hook of the electric trailer hook 1 is in the process of retraction, as described in Embodiment 1.

[0108] If the first information is the same as the first preset information, the power-operated tailgate is prohibited from being opened. If the second information is the same as the second preset information, the power-operated tailgate is also prohibited from being opened.

[0109] Still refer to Figure 3 As shown, the acquisition module in this embodiment is an electric trailer module 4 connected to the electric trailer hook 1. Specifically, the electric trailer hook 1 mainly includes a trailer hook drive device, which can be, for example, a drive motor, and the drive motor is connected to the electric trailer module 4. During operation, the drive motor sends second information about the trailer hook being in motion to the electric trailer module 4. This second information includes both signals indicating that the trailer hook is in the deployment process and signals indicating that the trailer hook is in the retraction process.

[0110] In the above embodiments, the second information is preferably a signal that the trailer hitch is in the deployment process, which can effectively prevent the power-operated tailgate from opening accidentally. It should be noted that when the second information includes both a signal that the trailer hitch is in the deployment process and a signal that the trailer hitch is in the retraction process, if the acquired operational information includes either a signal that the trailer hitch is in the deployment process or a signal that the trailer hitch is in the retraction process, the power-operated tailgate will be prohibited from opening, thus improving the reliability of preventing accidental opening of the power-operated tailgate.

[0111] It should be noted that in Embodiment 1 and Embodiment 2, since the preset operation information includes at least the first preset information and the second preset information, that is, the preset operation information may include multiple signals, and the obtained operation information includes the preset operation information, specifically, when the operation information obtained by the acquisition module includes at least one of the preset operation information, the electric sensor tailgate is prohibited from being opened, which has a better effect on preventing the electric sensor tailgate from being opened accidentally.

[0112] For example, if the acquisition module only obtains the first information that the electric trailer hook 1 is in the unlocked state, the electric sensor tailgate should be prohibited from being opened. If the acquisition module only obtains the second information that the trailer hook of the electric trailer hook 1 is in motion, the electric sensor tailgate should also be prohibited from being opened. If the acquisition module obtains both the first information requesting that the electric trailer hook 1 is in the running state and the second information that the trailer hook of the electric trailer hook 1 is in the running process, the electric sensor tailgate should also be prohibited from being opened.

[0113] The first information requesting that the electric trailer hitch 1 be in the operating state is triggered by the driver or passenger triggering the electric trailer hitch operation switch 5. The electric trailer hitch operation switch 5 is connected to the body domain controller 7. When the electric trailer hitch operation switch 5 is triggered by the driver or passenger, it sends the first information to the body domain controller 7. The tailgate sensor opening controller 6 specifically obtains the first information that the electric trailer hitch 1 is in the unlocked state from the body domain controller 7.

[0114] It should be noted that, in the above implementation method, when the driver or passenger manually clicks the electric trailer hook operation switch 5, the electric trailer hook operation switch 5 will send a command to deploy the electric trailer hook 1 and also send a command to retract the electric trailer hook 1.

[0115] The vehicle body domain controller 7 is connected to the electric trailer hitch operation switch 5 and the tailgate sensor opening controller 6 respectively, so that the tailgate sensor opening controller 6 can obtain the first information from the electric trailer hitch operation switch 5 through the vehicle body domain controller 7. This method is only a preferred implementation method, which makes it convenient to arrange the tailgate control device on the whole vehicle and requires less modification to the existing vehicle structure, so as to realize the tailgate control method as in Embodiment 1.

[0116] It should also be noted that in this embodiment, when the electric trailer hook operation switch 5 is triggered, the first information requesting the electric trailer hook 1 to be in the operating state is sent to the vehicle body domain controller 7, and the vehicle body domain controller 7 sends a control signal to the electric trailer module 4, which in turn sends a control signal to the electric trailer hook 1 to control the electric trailer hook 1 to perform the deployment process.

[0117] In addition, the electric trailer hitch operating switch 5 can also be connected to the electric trailer module 4 instead of the vehicle body domain controller 7. In this case, the first message requesting the electric trailer hitch 1 to be in operation will be directly sent to the electric trailer module 4, which will then send a control signal to the electric trailer hitch 1 to control it to perform the deployment process. Alternatively, the electric trailer hitch operating switch 5 can also be directly connected to the trailer hitch drive device of the electric trailer hitch 1, thus directly controlling the electric trailer hitch 1 to perform the deployment action.

[0118] In other embodiments, the electric trailer hitch operation switch 5 can also be connected to the tailgate sensor opening controller 6. When the electric trailer hitch operation switch 5 is operated by the driver or passenger, the electric trailer hitch operation switch 5 can directly send the first information requesting the electric trailer hitch 1 to be in operation to the tailgate sensor opening controller 6, thereby facilitating the implementation of the tailgate control method as described in Embodiment 1.

[0119] In this embodiment, the electric trailer module 4 is connected to the body domain controller 7. The second information obtained by the electric trailer module 4 can be sent to the body domain controller 7, while the tailgate sensor opening controller 6 obtains the second information from the body domain controller 7.

[0120] It should be noted that in this embodiment, the body domain controller 7 is connected to the electric trailer module 4 and the tailgate sensor opening controller 6 respectively. Therefore, the tailgate sensor opening controller 6 obtains the second information from the electric trailer module 4 through the body domain controller 7. In this way, the tailgate control device is convenient to arrange on the whole vehicle, and the modification to the existing vehicle structure is small, so the tailgate control method as in Embodiment 1 can be realized.

[0121] In other embodiments, the electric trailer module 4 can be connected to the tailgate sensor opening controller 6, for example. The second information obtained by the electric trailer module 4 can be directly sent to the tailgate sensor opening controller 6. In this case, the tailgate control method as in Embodiment 1 can be realized without going through the vehicle body domain controller 7.

[0122] For example, the electric trailer hook 1 is connected to the tailgate sensor opening controller 6. The second information that the trailer hook is in motion can also be directly sent to the tailgate sensor opening controller 6. In this case, the tailgate control method as in Embodiment 1 can be realized without going through the electric trailer module 4.

[0123] As a preferred implementation method, continue to refer to Figure 3 As shown, the control module is preferably a body domain controller 7 connected to the electric trailer module 4 and the tailgate sensor opening controller 6. This eliminates the need for additional hardware; the existing body domain controller 7 on the vehicle can still be used to implement the tailgate control method as described in Embodiment 1.

[0124] To better understand the tailgate control device of this embodiment, please refer to... Figure 3 As shown, in this embodiment, the sensing antenna 2 is connected to the tailgate sensing opening controller 6, and the tailgate sensing opening controller 6 is connected to the vehicle body domain controller 7.

[0125] In terms of specific structure, the sensing antenna 2 is, for example, an existing moving object sensing sensor. When it senses a kicking action, it sends a signal to the tailgate sensing controller 6 indicating that a kicking action has been sensed. Since the moving object sensing sensor can only sense whether an object is moving, but cannot distinguish whether the object being activated is a kicking action or the action of the electric trailer hook 1 unfolding or retracting, the moving object sensing sensor sends a signal to the tailgate sensing controller 6 during the action of the electric trailer hook 1 unfolding or retracting.

[0126] In addition to receiving signals from a foot kick, the tailgate sensor opening controller 6 can also obtain preset operating information from the vehicle body domain controller 7. The preset operating information includes a first preset information requesting that the electric trailer hitch 1 be in operation, and a second preset information that the trailer hitch of the electric trailer hitch 1 is in motion.

[0127] Therefore, according to the control method of the tailgate in Embodiment 1, when the acquired operating information includes preset operating information, the tailgate sensor opening controller 6 prohibits the electric sensor tailgate from being opened. That is, at this time, the tailgate sensor opening controller 6 prohibits the sending of the preset tailgate opening signal to the vehicle domain controller 7.

[0128] In a preferred embodiment, the vehicle domain controller 7 is also connected to the tailgate controller 8, and the tailgate controller 8 is connected to the tailgate lock 9. When the vehicle domain controller 7 receives a preset tailgate opening signal, it will send control information to the tailgate controller 8, which will then control the tailgate lock 9 to unlock. The tailgate lock 9 will then feed back the lock status to the tailgate controller 8.

[0129] It should be understood that in the above structure, the body domain controller 7 controls the tailgate lock 9 through the tailgate controller 8. Alternatively, the body domain controller 7 can be directly connected to the tailgate lock 9. In this case, the command from the body domain controller 7 to open the tailgate can be sent directly to the tailgate lock 9 without going through the tailgate controller 8. However, Figure 3 The exemplary structure shown is more convenient to arrange on the whole vehicle, requires less modification to the vehicle structure, and can realize the tailgate control method as in Embodiment 1 without adding hardware.

[0130] In this embodiment, the vehicle domain controller 7 is also connected to the vehicle electronic stability system 3. The vehicle domain controller 7 can obtain the vehicle speed signal from the vehicle electronic stability system 3. When the obtained vehicle speed signal is below a preset speed threshold, such as 5 km / h in Embodiment 1, the vehicle domain controller 7 allows the electric induction tailgate to be opened. When the obtained operating information does not include preset operating information, the electric induction tailgate is allowed to be opened, which helps to improve driving safety.

[0131] It should be noted that the control device for the rear door provided in Embodiment 2 is only illustrated by the above-mentioned division of functional modules when implementing the control method for the rear door in Embodiment 1. In actual applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above.

[0132] Furthermore, the control device provided in this embodiment and the control method for the rear door in Embodiment 1 are based on the same concept. For example, the acquisition module and the processing module can perform other functions. The specific implementation process is described above and will not be repeated here.

[0133] It should be noted that the control device in this embodiment may further include one or more processors and one or more memories. The processor may include one or more processing cores, such as a quad-core processor, an octa-core processor, etc. The processor may be implemented using at least one hardware form selected from DSP (Digital Signal Processing), FPGA (Field Programmable Gate Array), and PLA (Programmable Logic Array). The processor may also include a main processor and a coprocessor. The main processor, also known as a CPU (Central Processing Unit), is used to process data in the wake-up state; the coprocessor is a low-power processor used to process data in the standby state.

[0134] In a preferred embodiment, the processor may integrate a GPU (Graphics Processing Unit), which is responsible for rendering and drawing the content required to be displayed on the screen. In some embodiments, the processor may also include an AI (Artificial Intelligence) processor for handling computational operations related to machine learning. The memory may include one or more computer-readable storage media, which may be non-transitory. The memory may also include high-speed random access memory and non-volatile memory, such as one or more disk storage devices or flash memory devices.

[0135] In a preferred embodiment, the non-transitory computer-readable storage medium in the memory is used to store at least one computer program, which is executed by a processor to implement the vehicle speed limiting method of this embodiment. Those skilled in the art will understand that the control device may include, in addition to a memory and a processor, more or fewer components, combinations of certain components, or different component arrangements.

[0136] Furthermore, this embodiment also relates to a computer-readable storage medium storing a computer program thereon, which, when executed by a processor, enables the control method for the rear door as described in Embodiment 1.

[0137] At this point, a general example of a computer-readable storage medium is a memory. Furthermore, computer-readable storage media include both permanent and non-permanent, removable and non-removable media, and information storage can be achieved by any method or technology.

[0138] Information can be computer-readable instructions, data structures, program modules, or other data. Examples of computer-readable storage media include, but are not limited to, phase-change memory (PRAM), static random access memory (SRAM), dynamic random access memory (DRAM), other types of random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory or other memory technologies, optical discs, read-only memory (CD-ROM), digital versatile optical discs (DVDs) or other optical data storage devices, floppy disks, magnetic tape cassettes, magnetic magnetic disk storage or other magnetic storage devices, or any other non-transfer medium that can be used to store information that can be accessed by a computing device.

[0139] The computer-readable storage medium of this embodiment has the same beneficial effects as the aforementioned vehicle speed limiting method compared to the prior art, and will not be described again here.

[0140] In addition, this embodiment also relates to a vehicle that includes the above-mentioned control device for the tailgate. The control device for the tailgate can be set up separately or integrated with an existing vehicle control device.

[0141] In this embodiment, the vehicle, by applying the above-mentioned tailgate control device, can effectively prevent the tailgate from being accidentally opened during the operation of the tow hook, so that the electric tow hook 1 and the electric tailgate function can be integrated into the vehicle without affecting each other. The electric tow hook 1 configuration and the electric tailgate configuration can coexist on the vehicle without adding hardware configuration, which is conducive to improving the driving experience of drivers and passengers.

[0142] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
