[0043] It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0044] In a first aspect, an embodiment of the present invention provides a vehicle tailgate control method.

[0045] Figure 1 A schematic flow chart of a vehicle tailgate control method according to an embodiment of the present invention is shown.

[0046] Reference Figure 1 In one embodiment, the vehicle tailgate control method includes the following steps:

[0047] S11, obtaining a sensing signal, wherein the sensing signal is generated by a photoelectric sensor in response to a user action;

[0048] In this embodiment, the photoelectric sensor is a device that converts light signals into electrical signals. Its operating principle is based on the photoelectric effect. The photoelectric effect refers to the phenomenon in which, when light shines on certain substances, the electrons in the substance absorb the energy of the photons, causing a corresponding electrical effect. User actions cause the light signal received by the photoelectric sensor to change, thereby generating a corresponding sensing signal. Therefore, based on the specific sensing signal, it can be determined that the user has performed a specific action, requesting the tailgate to be opened or closed. It is understandable that the need for automatic triggering often occurs in usage scenarios where the user is holding an object in both hands. To facilitate operation, the user action is specifically a movement of the user's legs or feet, such as shaking the foot in a specific pattern.

[0049] Figure 2 A schematic structural diagram of a photoelectric sensor and a trigger mechanism in one embodiment of the present invention is shown.

[0050] Reference Figure 2 In one embodiment, the photoelectric sensor is configured as a through-beam photoelectric sensor, and the trigger mechanism is configured to move in response to user movements. The through-beam photoelectric sensor includes a receiving end and a transmitting end, respectively positioned on either side of the trigger mechanism's movement path. The trigger mechanism is provided with a through hole. When the through hole of the trigger mechanism moves between the receiving end and the transmitting end, the optical path between the receiving end and the transmitting end is connected, causing the receiving end to activate and output a sensing signal, such as a high-level signal. For example, the trigger mechanism is configured as a foot pedal.

[0051] S12: If the sensing signal meets the opening condition, the tailgate is controlled to open;

[0052] In this embodiment, the opening condition refers to a specific pattern that the sensing signal generated by the photoelectric sensor in response to the user's tailgate opening request must meet. When the sensing signal meets the opening condition, it is determined that the user has requested tailgate opening, and the tailgate is then controlled to open. It will be understood that the opening condition can be set as needed to conform to specific triggering logic and minimize false triggering.

[0053] In one embodiment, before the step of controlling the tailgate to open, the step further includes: controlling the rear of the vehicle body to descend to a preset height. The preset height is lower than the height of the rear of the vehicle body in normal driving mode. In this way, for models such as SUVs with high trunk heights, it is convenient for users to load heavy objects into the trunk, saving time and effort, while reducing the risk of scratching the vehicle. Specifically, this setting is for vehicles equipped with ASC (Active Suspension Controller, active suspension system), using the active suspension system to adjust the vehicle body height. The active suspension system can be any of an air suspension system, a hydraulic suspension system, and an electromagnetic suspension system.

[0054] Furthermore, in one embodiment, controlling the rear of the vehicle to descend to a preset height includes: detecting whether there is an obstacle during the vehicle's descent; if so, maintaining the rear of the vehicle at its current height and outputting an obstacle warning; if not, controlling the vehicle to descend to the preset height. This prevents the rear of the vehicle from colliding with obstacles during descent, potentially causing vehicle damage or even accidents. Specifically, a distance sensor is provided at the bottom of the rear bumper. When the distance sensor detects that the distance to an obstacle is less than the difference between the current height and the preset height, the vehicle maintains the current height and outputs an obstacle warning.

[0055] Furthermore, in one embodiment, before the step of controlling the rear portion of the vehicle body to descend to a preset height, the method further includes:

[0056] Determine whether the vehicle meets the working conditions of the active suspension system.

[0057] In this embodiment, since controlling the rear of the vehicle to descend to a preset height relies on the control of the active suspension system, it is necessary to at least ensure that the active suspension system is fault-free and that the vehicle is not in active suspension maintenance mode or transport mode. Furthermore, to avoid collisions or interference with the vehicle during the raising or lowering process, some active suspension systems require that all four doors, the front hood, and the tailgate be closed, and that the vehicle charging plug be unplugged, before adjusting the vehicle height. If the active suspension system is an air suspension system, to ensure that the vehicle can return to its normal height, the air pump must be in a normal state or the air tank pressure must be sufficient.

[0058] S13: If the sensing signal meets the closing condition, the tailgate is controlled to close.

[0059] In this embodiment, the closing condition refers to a specific pattern that the sensing signal generated by the photoelectric sensor in response to the user's tailgate closing request must meet. When the sensing signal meets the closing condition, it is determined that the user requested to close the tailgate, and the tailgate is then controlled to close. It will be understood that the closing condition can be set as needed to conform to specific triggering logic to minimize false triggering.

[0060] In one embodiment, after controlling the tailgate to close, the method further includes: determining the vehicle's driving mode; and controlling the rear portion of the vehicle to rise to a height that matches the driving mode. Thus, after the trunk is loaded and the tailgate is closed, the rear portion of the vehicle can rise to a height that matches the current driving mode, facilitating normal vehicle operation.

[0061] Therefore, this embodiment uses a photoelectric sensor to generate a sensing signal in response to user actions, and uses this sensing signal to determine whether the tailgate needs to be opened or closed. Photoelectric sensors are much cheaper than ultrasonic sensors and cameras, and the triggering logic of the sensing signal can be easily configured as needed, effectively reducing false triggering.

[0062] Figure 3 A schematic flow chart of a vehicle tailgate control method in another embodiment of the present invention is shown.

[0063] Reference Figure 3 In one embodiment, the vehicle tailgate control method includes the following steps:

[0064] S21. When the vehicle is unlocked, the trigger mechanism is unlocked so that the trigger mechanism can trigger the photoelectric sensor to generate a sensing signal in response to the user's action.

[0065] In this embodiment, the user must first unlock the vehicle, disengaging the trigger mechanism. This mechanism can then trigger the photoelectric sensor to generate a sensing signal, thereby controlling the opening or closing of the tailgate. Otherwise, when the vehicle is locked, the trigger mechanism is also locked, preventing the photoelectric sensor from generating a sensing signal. This further reduces false triggering and helps protect the user's property. For example, the trigger mechanism is configured as a foot pedal, and the vehicle is equipped with a foot pedal locking mechanism. Unlocking the trigger mechanism includes controlling the foot pedal locking mechanism to release the foot pedal.

[0066] S22, detecting whether the two photoelectric sensors are faulty;

[0067] If both photoelectric sensors are not faulty, the on condition is set as the sensing signals of the two photoelectric sensors are generated in a first preset order, and the off condition is set as the sensing signals of the two photoelectric sensors are generated in a second preset order;

[0068] If one of the photoelectric sensors fails, a fault alarm is output, and the on condition is set to any photoelectric sensor generating a first preset number of sensing signals within a preset time, and the off condition is set to any photoelectric sensor generating a second preset number of sensing signals within a preset time;

[0069] In this embodiment, there are two photoelectric sensors. Before acquiring sensing signals, both sensors are checked for malfunctions. A corresponding control strategy is selected based on the number of functioning photoelectric sensors. This ensures that the tailgate can automatically open and close as long as at least one photoelectric sensor is functioning properly, thereby improving system robustness. Specifically, if both photoelectric sensors are functioning properly, a first control strategy is employed, corresponding to a first opening condition and a first closing condition. If one of the photoelectric sensors is faulty, a second control strategy is employed, corresponding to a second opening condition and a second closing condition.

[0070] Figure 4 A schematic diagram showing waveforms of sensing signals corresponding to a first on condition and a first off condition in one embodiment of the present invention is shown; Figure 5 A schematic diagram of waveforms of sensing signals corresponding to the second on condition and the second off condition in one embodiment of the present invention is shown.

[0071] Reference Figure 2 、 Figure 4 and Figure 5 In one embodiment, the two photoelectric sensors are respectively a first photoelectric sensor and a second photoelectric sensor. Figure 2 The 1# transmitting end is the transmitting end of the first photoelectric sensor, and the 2# transmitting end is the transmitting end of the second photoelectric sensor. Figure 4 and Figure 5 In the figure, 1# corresponds to the signal waveform of the first photoelectric sensor, 2# corresponds to the signal waveform of the second photoelectric sensor, and the sensing signal is the high-level signal in the waveform.

[0072] Depend on Figure 4 It can be seen that the first opening condition is that the induction signal meets the triggering order of 1#, 2#, 2#, 1#, 1#, 2#, corresponding to Figure 2 The movement path of the trigger mechanism is from the far left to the far right, then the far left, then the far right. The trigger mechanism triggers the first photoelectric sensor and the second photoelectric sensor in sequence when it moves from the far left to the far right. The second photoelectric sensor and the first photoelectric sensor are triggered in sequence when it moves from the far right to the far left. Finally, the first photoelectric sensor and the second photoelectric sensor are triggered in sequence when it moves from the far left to the far right. The first closing condition is that the sensing signal meets the triggering order of 2#, 1#, 1#, 2#, 2#, 1#, corresponding to Figure 2The trigger mechanism moves from rightmost to leftmost, then rightmost to leftmost. As it moves from the rightmost to the leftmost side, it triggers the second photoelectric sensor and then the first photoelectric sensor. As it moves from the leftmost to the rightmost side, it triggers the first and second photoelectric sensors again. Finally, as it moves from the rightmost to the leftmost side, it triggers the second photoelectric sensor and then the first photoelectric sensor again. Therefore, the order in which the sensing signals from the first and second photoelectric sensors are generated allows the trigger mechanism's movement path to be determined, and thus, whether the user has requested to open or close the device.

[0073] Depend on Figure 5 As can be seen, the second opening condition is that any photoelectric sensor generates three sensing signals within 10 seconds, and the second closing condition is that any photoelectric sensor generates four sensing signals within 10 seconds. Optionally, after the sensing signals meet the opening or closing condition, the tailgate opening or closing control action is delayed by three seconds. Thus, the user's opening or closing request can be determined based on the number of sensing signals generated by the first or second photoelectric sensor within a preset time period.

[0074] S23, detecting whether the vehicle is in a power-off state;

[0075] Check whether the automatic loading enable switch is turned on;

[0076] If the vehicle is in a powered-off state and the automatic loading enable switch is turned on, the photoelectric sensor is activated.

[0077] In this embodiment, the automatic loading function is a function that automatically opens or closes the tailgate by recognizing user actions through a photoelectric sensor. It will be appreciated that this function does not need to be activated in all situations. Since the tailgate can be controlled by operating an in-vehicle switch when there are people inside the vehicle, the photoelectric sensor only needs to be triggered when no one is inside. In addition, the user decides whether to activate the automatic loading function before the next drive by turning the automatic loading enable switch on or off at the end of the previous drive. Therefore, if it is detected that the vehicle is in the power-off state and the automatic loading enable switch is on, it is determined that the user needs to activate the automatic loading function, and the photoelectric sensor is activated so that it can generate a sensing signal in response to the user's action. Optionally, the automatic loading enable switch is located in the IVI (In-Vehicle Infotainment).

[0078] S24, obtaining a sensing signal, wherein the sensing signal is generated by a photoelectric sensor in response to a user action;

[0079] S25: If the sensing signal satisfies the opening condition, the tailgate is controlled to open;

[0080] S26: If the sensing signal meets the closing condition, the tailgate is controlled to close.

[0081] In this embodiment, the analysis of steps S24 to S26 refers to the analysis of steps S11 to S13 in the above embodiment, and will not be repeated here.

[0082] Figure 6 A functional block diagram of a vehicle tailgate control method according to an embodiment of the present invention is shown.

[0083] Reference Figure 6 In one embodiment, the opening and closing of the tailgate has multiple triggering paths, including a Bluetooth key control switch, a mobile phone or other Internet tool control switch, a convenient loading physical switch, a convenient loading soft switch, and a convenient loading trigger action. Users can select the trigger path according to their needs. Among them, the Bluetooth key control switch and the mobile phone or other Internet tool control switch are usually when the vehicle is powered off and the non-driver has a loading demand, and rely on the driver to manually trigger them outside the vehicle. The convenient loading physical switch and the convenient loading soft switch are usually when the vehicle is powered on and the non-driver has a loading demand, and rely on the driver to manually trigger them inside the vehicle. Specifically, the convenient loading physical switch is set on the auxiliary instrument center control, and the convenient loading soft switch is set on the IVI. The convenient loading trigger action is usually when the vehicle is powered off and the driver has a loading demand, and it is automatically triggered by generating an induction signal through the trigger action. The above embodiments of the present invention mainly discuss the triggering path of the convenient loading trigger action.

[0084] Furthermore, in this embodiment, the tailgate opening action is linked to the lowering action of the rear body of the vehicle. The tailgate switch signal is transmitted by the BCM (Body Control Module) to the POT (Power Operation Tailgate) to control the opening and closing of the tailgate, and the raising and lowering of the rear body of the vehicle is controlled by the ASC. When receiving Bluetooth key signals, APP application signals of Internet tools such as mobile phones, convenient loading physical switch signals, convenient loading soft switch signals, and sensing signals, the BCM and ASC perform corresponding control operations. When receiving a signal representing an opening request, the ASC controls the rear body of the vehicle to descend to a preset height, and sends the system adjustment status and vehicle height level to the IVI and instrument for display. The BCM controls the POT to open the tailgate. When receiving a signal representing a closing request, the BCM controls the POT to close the tailgate. After the tailgate is closed, the ASC raises the rear body of the vehicle to a height that matches the current driving mode.

[0085] It should be noted that manually triggered switch signals should be linked. When any one of them switches to the on state and completes the control action, the other switch signals also switch to the on state to avoid signal conflicts. For example, when a user opens the tailgate via the Bluetooth key control switch, the Bluetooth key signal switches to the on state in response to the user operation. The app application signal, the convenient loading physical switch signal, and the convenient loading soft switch signal also switch to the on state in a coordinated manner. This allows the user to subsequently manually close the tailgate via any of the following methods: Bluetooth key control switch, mobile phone or other internet tool control switch, convenient loading physical switch, or convenient loading soft switch.

[0086] Furthermore, in this embodiment, in addition to operating the aforementioned switches and completing the triggering action, the tailgate closing trigger also includes increasing vehicle speed, turning on the automatic loading enable switch and arming the vehicle, and switching driving modes. Specifically, the tailgate is controlled to close if any of the following conditions are met: the Bluetooth key control switch is turned off, the mobile phone or other internet tool control switch is turned off, the convenient loading physical switch is turned off, the convenient loading soft switch is turned off, the vehicle speed exceeds a preset threshold, the automatic convenient loading enable switch is turned on and the vehicle is arming, or the driving mode is changed.

[0087] Furthermore, in this embodiment, the ASC is configured as an air suspension system. Before the ASC controls the rear vehicle body to descend to a preset height, it must obtain a power signal, an empty spring status signal, an empty spring height level signal, and a door signal to ensure that the air suspension system is functioning properly, the vehicle is not in air suspension system maintenance mode or transport mode, all four doors, the front hood, and the tailgate are closed, the vehicle charging plug is not plugged in, and the air pump is functioning normally or the air tank pressure is sufficient. Only then can the vehicle body height be adjusted. Before opening the tailgate, a gear position signal must be obtained to ensure that the vehicle is stationary and in P gear.

[0088] Furthermore, in this embodiment, when the tailgate is opened via a Bluetooth key control switch or an internet tool such as a mobile phone, a power signal must be obtained to ensure that the vehicle is powered off before the tailgate can be opened. When the tailgate is opened via a convenient loading trigger, a power signal and an automatic loading enable switch signal must be obtained to ensure that the vehicle is powered off and the automatic loading enable switch is enabled before the tailgate can be opened. When the tailgate is opened via a convenient loading physical switch or a convenient loading soft switch, a power signal must be obtained to ensure that the vehicle is powered on and the DC converter is enabled before the tailgate can be opened.
