[0002] Pickup trucks, trucks and other transport vehicles are usually equipped with cargo boxes, and the tailgate of the cargo box is a passage for users to load and unload cargo. When the tailgate needs to be opened to load and unload cargo, the cargo box is high from the ground, requiring users to climb in, which is inconvenient for users to load and unload cargo.

[0003] In the prior art, some vehicles use a composite rear panel as a tailgate of the cargo box to improve the convenience of loading and unloading cargo. When the composite rear panel is in an open state, it can provide a step for the user to improve the convenience of loading and unloading cargo.

[0085] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0086] It should be noted that, unlike conventional cargo box tailgates, the composite rear panel is composed of a lower rear panel and an upper rear panel arranged on top of the lower rear panel. When the composite rear panel is in a closed state, the upper rear panel and the lower rear panel are not separated. At this time, it has the same function as a conventional cargo box tailgate, which is used to cover the rear end opening of the vehicle cargo box to prevent the cargo in the cargo box from falling. When the composite rear panel is in an open state, the upper rear panel and the lower rear panel are separated. At this time, the lower rear panel is flipped to the rear end opening in an open state, and the upper rear panel is flipped relative to the lower rear panel to the bottom of the lower rear panel, and forms a step with the lower rear panel.

[0087] However, the composite rear panel in the prior art still needs to be opened or closed manually by the driver, which is cumbersome to operate. Especially when transporting goods, it is difficult for the user to quickly and conveniently control the opening of the composite rear panel, resulting in a poor user experience.

[0088] In order to solve the problem that the composite rear panel of a vehicle requires manual control by the user, resulting in a poor user experience, the present application aims to provide a control method for the composite rear panel of a vehicle, which can realize automatic control of the composite rear panel, so that the user can control the automatic opening of the composite rear panel without manual operation while ensuring operational safety, thereby effectively improving the user experience.

[0089] Reference Figure 1 , shows a structural schematic diagram of a composite rear panel provided by the present application, the composite rear panel includes an upper rear panel 2 and a lower rear panel 1, the upper rear panel 2 includes a connecting portion 21 and a pedal 22; the pedal 22 is connected to the lower rear panel 1 through the connecting portion 21, and the lower rear panel 1 is connected to the bottom of the rear end opening.

[0090] Specifically, the lower rear panel 1 can be flipped to open and close the rear end opening of the cargo box. When the lower rear panel 1 flips along one side of the cargo box to match the rear end opening of the cargo box, the upper rear panel 2 and the lower rear panel 1 are not separated. At this time, the rear end opening is in a closed state and the cargo box is closed. When the lower rear panel 1 flips 90° to the side away from the cargo box, the rear end opening is in an open state, and the inner surface of the lower rear panel 1 faces upward. At this time, the inner surface of the lower rear panel 1 is an extension of the bottom plate of the cargo box, which is equivalent to the second step; at the same time, the upper rear panel 2 will be separated from the lower rear panel 1 and flipped 90° to the side away from the lower rear panel 1. The pedal 22 in the upper rear panel 2 can be further flipped 90° relative to the lower rear panel 1, and then the pedal 22 can be flipped outward relative to the lower rear panel 1 to the bottom of the lower rear panel 1. At this time, the board surface of the pedal 22 is located on the inner surface of the lower rear panel 1 and is parallel to the inner surface of the lower rear panel 1, which is equivalent to the first step. In this way, the board surface of the pedal 22 and the inner surface of the lower rear plate 1 form a first step and a second step whose heights rise successively. Users can get on and off the cargo box through the pedal 22 and the lower rear plate 1, which improves the convenience of loading and unloading, and improves the safety of users in loading and unloading.

[0091] It should be noted that, in order to realize the electric control of the composite rear panel, the composite rear panel is also provided with a driving motor, which can specifically include a lower rear panel motor 4 and at least one upper rear panel motor 3. Among them, the upper rear panel motor 3 can adopt an electric support rod, and the upper rear panel 2 is connected to the lower rear panel 1 through two electric support rods, so that the upper rear panel motor 3 can control the upper rear panel 2 to flip, so as to realize the combination and separation between the upper rear panel 2 and the lower rear panel 1; the lower rear panel motor 4 is fixedly arranged inside the lower rear panel 1, and the lower rear panel motor 4 is connected to the cargo box through a hinge or other connecting parts, so that the lower rear panel motor 4 can use the cargo box as a fulcrum to drive the hinge to operate to drive the lower rear panel 1 to close or open.

[0092] Reference Figure 2 , shows a control method of a composite rear panel of a vehicle in the present application, which is applied to a central controller, and the method may include the following steps:

[0093] S201: In response to a composite rear panel opening request triggered by a user, triggering detection of a smart key of a vehicle.

[0094] It should be noted that the execution subject of this embodiment is the central controller of the vehicle, which is an electronic device with data processing, network communication and program running functions, such as ECU (Electronic Control Unit), BCM (Body Control Module), CEM (Central Electronic Module), etc. This embodiment will be described with CEM as the execution subject. CEM integrates the original BCM, GW (gateway), ALCM (ambient light controller) and other controllers, and as the main control unit of the vehicle body, it can realize functions such as message routing and forwarding, body control, and network management.

[0095] It should be further explained that the vehicle can be a pickup truck, a truck or other vehicle type equipped with a cargo box and a composite rear panel, the composite rear panel is provided with a tailgate controller, one end of the tailgate controller is connected to the CEM, and the other end of the tailgate controller is respectively connected to the lower rear panel motor and the upper rear panel motor, and the tailgate controller can control the lower rear panel motor and the upper rear panel motor to respectively drive the upper rear panel and the lower rear panel to open according to the tailgate opening instruction sent by the central controller, or control the lower rear panel motor and the upper rear panel motor to respectively drive the upper rear panel and the lower rear panel to close according to the tailgate closing instruction sent by the central controller.

[0096] In this embodiment, when the user needs to open the composite rear panel, the composite rear panel opening request can be triggered in a variety of ways. For example, the user can trigger a preset rear panel button on the smart key, or trigger a micro switch pre-set on the composite rear panel, or trigger a preset virtual button on the central control display screen, or directly issue a voice command to send a composite rear panel opening request to the CEM, and the CEM responds to the composite rear panel opening request triggered by the user and triggers the detection of the smart key.

[0097] In this embodiment, after receiving the composite rear panel opening request triggered by the user, the CEM will send detection information to the smart key according to the preset detection cycle. If feedback information returned by the smart key in response to the detection information is received, it is determined that the smart key is detected and subsequent steps are executed; if no feedback information returned by the smart key in response to the detection information is received after a preset number of consecutive detection cycles, it is determined that the smart key is not detected and subsequent steps are not executed.

[0098] Furthermore, in order to accurately locate the smart key and avoid false triggering by other pedestrians, after obtaining the feedback information returned by the smart key in response to the detection information, the CEM will determine whether the smart key is in a preset valid area based on the location information in the feedback information; and when it is detected that the smart key is in the valid area, it is determined that the smart key is detected and subsequent steps are executed.

[0099] S202: When the smart key is detected, a tailgate opening command is sent to the tailgate controller, so that the tailgate controller responds to the tailgate opening command, obtains first state information of the vehicle, and controls the composite rear panel to move to the open position when the first state information satisfies the tailgate opening condition, so that the lower rear panel is flipped to the rear end opening in the open state, and the pedal is flipped relative to the lower rear panel to form a step between the pedal surface and the inner surface of the lower rear panel.

[0100] In this embodiment, if the CEM detects the smart key, it determines that the user is in the valid area, and then sends a tailgate opening command to the tailgate controller. After receiving the tailgate opening command, the tailgate controller will obtain the first state information of the vehicle to determine whether the tailgate can be opened.

[0101] Specifically, in order to avoid unnecessary additional wiring, the target state information in the first state information that needs to be additionally obtained by the tailgate controller will be obtained through the CEM, that is, when the CEM sends the tailgate opening instruction, it will also send the target state information to the tailgate controller. For example, when the state information includes the current vehicle speed, the tailgate controller can obtain the current vehicle speed through the CEM, and there is no need to arrange additional data lines for connecting the tailgate controller and the vehicle speed sensor.

[0102] In this embodiment, if the tailgate controller detects that the first state information satisfies the tailgate opening condition, it drives the lower rear panel motor to perform the opening operation to move the composite rear panel to the open position; if the tailgate controller detects that the first state information does not satisfy the tailgate opening condition, it feeds back corresponding failure prompt information, which is used to prompt the content in the first state information that does not satisfy the tailgate opening condition. For example, when the user triggers the composite rear panel opening request, if the current vehicle speed does not meet the corresponding vehicle speed condition, the failure prompt information will be fed back to prompt that the vehicle speed is too fast and the composite rear panel cannot be opened.

[0103] In this embodiment, by judging whether the first state information satisfies the tailgate opening condition, the composite rear panel can be automatically opened while ensuring safety.

[0104] The embodiment of the present application can respond to a composite rear panel opening request triggered by a user to achieve automatic control of the composite rear panel, so that the user can control the automatic opening of the composite rear panel while ensuring operational safety without manual operation. Compared with manual opening of the composite rear panel by the user, it is more convenient, fast and intelligent, and can effectively improve the user experience.

[0105] In a feasible implementation, in order to further realize the automatic closing function of the composite rear panel, after S202, the control method of the composite rear panel of the vehicle may further include the following steps:

[0106] S203: In response to a composite rear panel closing request triggered by a user, a tailgate closing instruction is sent to a tailgate controller, so that the tailgate controller responds to the tailgate closing instruction, obtains second state information of the vehicle, and controls the composite rear panel to move to a closed position when the second state information satisfies the tailgate closing condition, so that after the lower rear panel is flipped over to the rear end opening is in a closed state, the upper rear panel is flipped over to be in the same plane as the lower rear panel.

[0107] In this embodiment, after completing the transport work, the user can trigger a composite rear panel closing request to achieve automatic closing of the composite rear panel.

[0108] In a specific implementation, after obtaining the composite rear panel closing request, the CEM will send a tailgate closing instruction to the tailgate controller. After receiving the tailgate closing instruction, the tailgate controller will obtain the second state information of the vehicle to determine whether the composite rear panel can be closed.

[0109] In this embodiment, by judging whether the second state information satisfies the closing condition of the rear baffle, the automatic closing of the composite rear panel can be achieved while ensuring safety.

[0110] In a feasible implementation manner, the control method of the vehicle composite rear panel may further include the following steps:

[0111] S204: When it is determined that the vehicle meets the preset projection conditions, projecting a preset projection control interface to the outside of the vehicle.

[0112] In this embodiment, in order to facilitate the user to trigger the corresponding user request for the composite rear panel, the CEM will automatically project the projection control interface to the outside of the vehicle when it detects that the vehicle meets the preset projection conditions. The projection conditions are used to determine whether the vehicle can project the projection control interface to the outside of the vehicle.

[0113] In this embodiment, in order to prevent other pedestrians from accidentally triggering the projection control interface, the projection condition can be set as: the user is in the preset sensing area and there is a smart key in the preset sensing area. In other words, when the CEM detects that the user is in the preset sensing area and there is a smart key in the preset sensing area, it can determine that the vehicle meets the preset projection condition and then project the projection control interface to the outside of the vehicle.

[0114] In a specific implementation, CEM can perform human body detection in a preset sensing area through a preset sensor, and then trigger the detection of the vehicle's smart key when it detects that a user enters the preset sensing area, and project a preset projection control interface to the outside of the vehicle when it detects that the smart key is located in the preset sensing area.

[0115] In a specific implementation, the preset sensing area can be set as the area outside the vehicle facing the rear end of the cargo box, that is, after the user walks into the preset sensing area, the CEM can detect the user. Specifically, the CEM can collect the image to be identified in the preset sensing area through the infrared sensor, camera and other sensors set at the rear end of the cargo box, and perform human body recognition on the image to be identified to determine whether the user has entered the preset sensing area.

[0116] It should be noted that the effective area may be the same as the preset sensing area or may be different from the preset sensing area. For example, when the distance detection accuracy of the vehicle Bluetooth module is low, the effective area may be set to include the preset sensing area; or when the distance detection accuracy of the vehicle Bluetooth module is high, part of the preset sensing area may be set as the effective area.

[0117] In this embodiment, to facilitate user operation, the projection control interface can be projected to the area where the user is currently located, and a corresponding control mark can be displayed on the projection control interface to instruct the user to trigger a corresponding user request through the control mark.

[0118] S205: When it is determined that the user is located on the projection control interface, a posture image of the user is acquired.

[0119] In this embodiment, after projecting the projection control interface to the outside of the vehicle, the CEM will detect whether the user is located on the projection control interface, and then obtain the user's posture image when it is determined that the user is located on the projection control interface, and then through the recognition of the posture image, the user request triggered by the user can be effectively obtained. The posture image refers to an image reflecting the user's action.

[0120] In a specific implementation, the user's posture image can be obtained through sensors such as cameras. To avoid being blocked and improve the image acquisition effect, the camera can be set in a preset area at the rear end of the cargo box that will not be blocked by the composite rear panel. For example, the preset area can be above the taillights at the rear end of the cargo box.

[0121] S206: When it is detected that the first preset gesture exists in the gesture image, determine that the user request is a composite rear panel opening request.

[0122] In a specific implementation, the user can trigger the composite rear panel opening request by performing a plurality of first preset gestures. For example, the user can trigger the composite rear panel opening request by stepping on the control mark; or stand behind the control mark and trigger the composite rear panel opening request by performing a preset action indicating "opening", such as making a fist, raising a hand, etc.

[0123] S207: When it is detected that the second preset gesture exists in the gesture image, determine that the user request is a composite rear panel closing request.

[0124] In a specific implementation, the user can trigger the composite rear panel opening request by performing a plurality of second preset gestures. For example, the user can trigger the composite rear panel closing request by stepping on the control mark twice; or trigger the composite rear panel closing request by performing a preset action indicating "closing", such as performing an "OK" gesture, an "X" gesture, etc. with the hand.

[0125] In this embodiment, by projecting the projection control interface to the outside of the vehicle, the user can trigger the corresponding user request by making corresponding preset gestures according to his own composite rear panel usage needs, thereby realizing automatic opening and closing of the composite rear panel.

[0126] In a feasible implementation, S204 may specifically include the following sub-steps:

[0127] S204-1: When the smart key is detected, obtain the light intensity of the environment where the vehicle is located.

[0128] In this embodiment, in order to improve the display effect of the projection control interface, after detecting the smart key, the CEM will obtain the light intensity of the vehicle environment, and then adaptively adjust the projection brightness of the projection control interface according to the light intensity.

[0129] In a specific implementation, multiple light intensity sensors can be set in different areas of the vehicle's outer surface. For example, three light intensity sensors can be set at the vehicle's rear license plate, left door handle, and right door handle, respectively. The light intensity of the three areas is then obtained through the three light intensity sensors, and the average value of the light intensity of the three areas is determined as the light intensity of the vehicle's environment.

[0130] S204-2: Determine the target projection brightness of the projection control interface based on the light intensity.

[0131] It should be noted that different light intensities correspond to different projection brightness.

[0132] In a specific implementation, the CEM pre-stores a projection brightness mapping table representing different projection brightnesses corresponding to different illumination intensities. After obtaining the illumination intensity, the CEM can determine the target projection brightness corresponding to the illumination intensity by looking up the table.

[0133] S204-3: Projecting the projection control interface to the outside of the vehicle according to the target projection brightness.

[0134] In this embodiment, the CEM projects the projection control interface according to the target projection brightness, so that the projection control interface can better adapt to the current environment of the vehicle, and then display the projection control interface to the user more clearly, making it easier for the user to perform corresponding operations on the projection control interface.

[0135] In this embodiment, if the CEM detects that the projection lamp lens is dirty during projection, it will control the vehicle instrument to output a projection alarm message to remind the user that the projection lamp lens is blocked. Specifically, the projection alarm message can be output by outputting a voice prompt message and controlling the projection lamp to flash at a high frequency.

[0136] In a feasible implementation manner, the control method of the vehicle composite rear panel may further include the following steps:

[0137] S208: Acquire the current vehicle speed and the current composite tailgate state information sent by the tailgate controller.

[0138] In this embodiment, the tailgate controller sends the updated current composite rear plate status information to the CEM according to a preset update frequency; the CEM controls the vehicle instrument to display the current composite rear plate status information.

[0139] In a specific implementation, the current composite rear panel status information can be displayed in a variety of ways. For example, the vehicle instrument can be a central control display screen, or a prompt icon separately set on the center console. After obtaining the current composite rear panel status information, the CEM can display the current composite rear panel status information through the central control display screen, or control the prompt icon to display the target pattern corresponding to the current composite rear panel status information and flash. Among them, the prompt icon can include a first pattern indicating that the composite rear panel is fully open, a second pattern indicating that the composite rear panel is fully closed, and a third pattern indicating that the composite rear panel is half open.

[0140] In this embodiment, after the CEM obtains the current composite tailgate state information sent by the tailgate controller, it will obtain the current vehicle speed and then determine whether the vehicle is at a faster driving speed at this time.

[0141] S209: When the current vehicle speed is greater than the first vehicle speed threshold and the current composite rear panel status information is in an open state, output a prompt message.

[0142] In this embodiment, the first vehicle speed threshold can be set to 5 km / h, that is, when it is detected that the current vehicle speed is greater than 5 km / h and the composite rear panel is in an open state, a prompt message is output, which is used to prompt that the composite rear panel is not closed.

[0143] In a specific implementation, the prompt information can be output in a combination of sound and icon, that is, while controlling the warning icon to flash, the corresponding warning voice is output.

[0144] In this embodiment, by real-time monitoring of the current vehicle speed and the current composite rear panel status information, timely reminders can be given when it is detected that the composite rear panel is not closed or not closed properly, thereby preventing the cargo in the cargo box from falling and affecting the vehicle and road safety.

[0145] Reference Figure 3 , shows another control method of a composite rear panel of a vehicle of the present application, which is applied to a tailgate controller. The method may include the following steps:

[0146] S301: Obtain a tailgate opening instruction sent by a central controller.

[0147] It should be noted that the execution subject of this embodiment is a tailgate controller, which is an electronic device with data processing, network communication and program running functions. Specifically, one end of the tailgate controller is connected to the central controller, and the other end of the tailgate controller is connected to the upper rear plate motor and the lower rear plate motor respectively. The tailgate controller is used to control the upper rear plate motor and the lower rear plate motor to operate in coordination according to the tailgate control instruction sent by the central controller, so as to realize the opening and closing of the composite rear plate.

[0148] It should be noted that the tailgate opening instruction is generated by the central controller in response to a composite tailgate opening request triggered by a user, triggering detection of the vehicle's smart key, and when the smart key is detected.

[0149] S302: In response to a tailgate opening instruction, obtaining first state information of the vehicle.

[0150] In this embodiment, in order to ensure the opening safety of the composite rear panel, after receiving the tailgate opening instruction, the tailgate controller will obtain the first state information of the vehicle to determine whether the composite rear panel can be controlled to perform the opening operation.

[0151] In a specific implementation, the first state information may specifically include the current vehicle speed, power mode, trailer state, and current composite rear plate state information. If the tailgate controller detects that the current vehicle speed is less than or equal to the second vehicle speed threshold, the power mode is the preset mode, the trailer state is the closed state, and the current composite rear plate state information is the closed state, it determines that the first state information meets the tailgate opening condition, and then controls the composite rear plate to perform the opening operation.

[0152] It should be noted that when the vehicle is in the trailer state, the rear bumper of the vehicle will be connected to other trapped vehicles through a towing rope. In order to avoid interference between the vehicle and the composite rear plate when in the trailer state, it is necessary to control the opening of the composite rear plate when the trailer state is closed.

[0153] It should be noted that the power mode indicates the power working mode of the whole vehicle, which may specifically include OFF mode, ACC mode, ON mode and CRANK mode. In the present embodiment, the preset mode may be set to OFF mode and ON mode. By limiting the power mode to the preset mode, the opening operation of the composite rear panel when the vehicle is in CRANK mode can be avoided. Among them, the CRANK mode corresponds to the START position of the vehicle keyhole. When starting the vehicle, the key is usually turned to the bottom, that is, the START position, to start the engine. After the ignition is successful, it will return to the ON mode and start successfully. Since the generator works suddenly in the CRANK mode, the voltage of the battery may rush very high at once, and it will not return to the normal level until the start is successful. Therefore, during the opening process of the composite rear panel, if the power mode is detected to be CRANK mode, it is necessary to control the composite rear panel to stop the action, and after the vehicle exits the CRANK mode, the composite rear panel continues to open.

[0154] S303: When the first state information satisfies the tailgate opening condition, the composite rear panel is controlled to move to the open position, so that the lower rear panel is flipped to the rear end opening in the open state, and the pedal is flipped relative to the lower rear panel to form a step between the pedal surface and the inner surface of the lower rear panel.

[0155] In the specific implementation, continue to refer to Figure 1After determining that the first state information meets the tailgate opening condition, the tailgate controller will send a lower rear plate opening signal to the lower rear plate motor, so that the lower rear plate is driven by the lower rear plate motor to flip 90° to the side away from the cargo box, so that the rear end opening of the cargo box is in an open state, and the inner surface of the lower rear plate faces upward. At this time, the inner surface of the lower rear plate serves as an extension of the bottom plate of the cargo box, which is equivalent to the second step; at the same time, the tailgate controller will also send an upper rear plate opening signal to the upper rear plate motor, so that the upper rear plate is driven by the upper rear plate motor to separate from the lower rear plate and flip 90° to the side away from the lower rear plate, and the pedal in the upper rear plate can be further flipped 90° relative to the lower rear plate, and then the pedal can be flipped outward relative to the lower rear plate to the bottom of the lower rear plate. At this time, the board surface of the pedal is located on the inner surface of the lower rear plate and is parallel to the inner surface of the lower rear plate, which is equivalent to the first step.

[0156] It should be noted that in order to achieve fully automatic opening of the composite rear panel, a pedal motor can be further arranged in the upper rear panel, and the pedal motor is connected to a pedal support rod, and then the tailgate controller can send a pedal opening command to the pedal motor, so that the pedal motor drives the pedal support rod to drive the pedal to flip 90° relative to the upper rear panel to form a first step.

[0157] In this embodiment, the tailgate controller can control the lower rear plate motor, the upper rear plate motor and the pedal motor to run simultaneously, thereby realizing full-automatic and rapid opening of the composite rear plate.

[0158] The embodiment of the present application can respond to a composite rear panel opening request triggered by a user to achieve automatic control of the composite rear panel, so that the user can control the fully automatic opening of the composite rear panel without manual operation. Compared with manual opening of the composite rear panel by the user, it is more convenient, fast and intelligent, and can effectively improve the user experience.

[0159] In a feasible implementation, in order to further realize the automatic closing function of the composite rear panel, after S301, the control method of the composite rear panel of the vehicle may further include the following steps:

[0160] S304: Obtain a tailgate closing instruction sent by the central controller.

[0161] It should be noted that the tailgate closing instruction is generated by the central controller in response to a composite rear panel closing request triggered by a user.

[0162] S305: In response to the tailgate closing instruction, obtain second state information of the vehicle.

[0163] In this embodiment, in order to ensure the closing safety of the composite rear panel, after receiving the tailgate closing instruction, the tailgate controller will obtain the second state information of the vehicle to determine whether the composite rear panel can be controlled to perform the closing operation.

[0164] In a specific implementation, the second state information may include the current vehicle speed, the power mode, and the current composite rear panel state information. If the tailgate controller detects that the current vehicle speed is less than or equal to the second vehicle speed threshold, the power mode is the preset mode, and the current composite rear panel state information is in the open state, it is determined that the second state information meets the tailgate closing condition.

[0165] It should be noted that, since the composite rear panel is in the closing operation at this time, the trailer status of the vehicle is no longer detected.

[0166] S306: When the second state information satisfies the closing condition of the rear baffle, the composite rear panel is controlled to move to the closed position, so that after the lower rear panel is flipped to the rear end opening is in the closed state, the upper rear panel is flipped to be in the same plane as the lower rear panel.

[0167] In this embodiment, considering that there is no limiting mechanism to limit the lower rear panel when the lower rear panel is in the open state, the upper rear panel may not be closed smoothly when the rear panel is in the open state.

[0168] In the specific implementation, in order to achieve the smooth closing of the composite back plate, continue to refer to Figure 1 After the tailgate controller determines that the second state information meets the tailgate closing condition, it will not control the upper and lower rear panels to close at the same time, but will first control the lower rear panel to flip to the rear opening in a closed state, and after detecting that the lower rear panel is closed, it will control the upper rear panel to flip to the same plane as the lower rear panel. After the lower rear panel is closed, the side panels on both sides of the cargo box will limit the lower rear panel, so the smooth closing of the upper rear panel can be effectively guaranteed.

[0169] It should be noted that when a pedal motor is provided in the upper rear panel, after the upper rear panel is closed, the pedal can be reset by controlling the pedal motor to drive the pedal support rod. Since the pedal can be automatically closed under the action of its own gravity when the upper rear panel is closed, a smaller driving force can be output to complete the automatic closing of the pedal.

[0170] In this embodiment, by determining whether the second state information satisfies the tailgate closing condition and closing the lower rear panel, the upper rear panel and the pedal in sequence, the composite rear panel can be automatically closed while ensuring safety.

[0171] In a feasible implementation manner, the control method of the vehicle composite rear panel may further include the following steps:

[0172] S307: In the process of controlling the composite rear plate to move to the open position, if it is detected that the duration of the stall current of the drive motor is greater than the duration threshold, the drive motor is controlled to reversely drive the composite rear plate to the closed position.

[0173] In this embodiment, the tailgate controller monitors whether the drive motor has a stall current in real time when controlling the opening of the composite rear plate, and triggers the timing of the duration when the stall current occurs, and then determines that the composite rear plate encounters an obstacle when the duration is greater than the duration threshold, and then triggers the corresponding anti-pinch function. The drive motor includes part or all of the lower rear plate motor, the upper rear plate motor, and the pedal motor.

[0174] S308: In the process of controlling the composite rear panel to move to the closed position, if it is detected that the duration of the stall current of the drive motor is greater than the duration threshold, the drive motor is controlled to reversely drive the composite rear panel to the open position.

[0175] In this embodiment, the tailgate controller will also monitor in real time whether the drive motor has a stall current when controlling the closing of the composite rear plate, and trigger the timing of the duration when the stall current occurs, and then determine that the composite rear plate encounters an obstacle when the duration is greater than the duration threshold, and then trigger the corresponding anti-pinch function. The drive motor includes part or all of the lower rear plate motor, the upper rear plate motor and the pedal motor.

[0176] In a specific implementation, different duration thresholds can be set for the lower rear plate motor, the upper rear plate motor, and the pedal motor. That is, for the lower rear plate motor, the anti-pinch function can be triggered when it is detected that the duration of the stall current of the lower rear plate motor is greater than the first duration threshold; for the upper rear plate motor, the anti-pinch function can be triggered when it is detected that the duration of the stall current of the upper rear plate motor is greater than the second duration threshold; for the pedal motor, the anti-pinch function can be triggered when it is detected that the duration of the stall current of the pedal motor is greater than the third duration threshold.

[0177] It should be noted that the first duration threshold, the second duration threshold and the third duration threshold can be set according to the stall current protection time corresponding to the lower rear plate motor, the upper rear plate motor and the pedal motor respectively, and it is only necessary to meet the condition that the first duration threshold, the second duration threshold and the third duration threshold are less than or equal to the stall current protection time corresponding to the lower rear plate motor, the upper rear plate motor and the pedal motor respectively.

[0178] In this embodiment, by monitoring the stall current of the lower rear plate motor, the upper rear plate motor and the pedal motor, the anti-pinch function can be triggered when a stall current occurs in any motor, thereby effectively ensuring the user's operating safety.

[0179] In the third aspect, based on the same inventive concept, refer to Figure 4The embodiment of the present application provides a vehicle canopy control device 400, which is applied to a central controller.

[0191] The projection brightness determination submodule is used to determine the target projection brightness of the projection control interface based on the light intensity; different light intensities correspond to different projection brightness;

[0192] The interface projection submodule is used to project the projection control interface to the outside of the vehicle according to the target projection brightness.
