Description

Technical Field

[0001] The present application relates to the field of vehicle technology, and in particular to an unlocking control device, method, vehicle and computer program product for an electric door. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] At present, in the vehicle door unlocking scenario, the vehicle door is unlocked by the vehicle door lock control module, and the door is opened to a certain gap. Although this unlocking method can meet the basic unlocking requirements of the door, when the door is blocked during the unlocking operation, especially in the unlocking scenario where the door is blocked by breaking ice, a large unlocking force is required to open the door to a certain gap. At this time, if the door is unlocked only by relying on the vehicle door lock control module, it is difficult to meet the needs of breaking ice to unlock and open the door, especially now that vehicles are gradually pursuing a design without door handles. If the opening gap of the electric door does not meet the requirements, there will be a risk of pinching the user's hand when the user extends his hand to the door gap to open the door. Summary of the invention

[0004] The purpose of this application is to at least solve the technical problem that existing vehicles cannot be successfully unlocked in ice breaking scenarios, and this purpose is achieved through the following technical solutions:

[0005] A first aspect of the present application provides an unlocking control device for an electric door, the unlocking control device comprising a door lock module and an electric control door module, the door lock module being connected to the electric control door module, wherein: the door lock module is used to start the unlocking operation of the electric door according to a user instruction, and control the electric door to open to a first unlocked state after the unlocking operation is completed; the electric control door module is used to start the door opening operation of the electric door after the unlocking operation is completed, and when the electric door is in an ice-breaking scene, the electric control door module performs a power-assist operation on the electric door, and the power-assist operation is used to open the electric door to the first unlocked state after the unlocking operation is completed.

[0006] When the vehicle is in a scenario where unlocking is blocked, such as breaking ice, although the door lock module can drive the electric door's latch to open, when the electric door needs to be opened under the reaction force of the door seal, the electric door cannot be opened at a specified angle or distance due to the constraint of ice or other damping forces. At this time, the door lock module will mistakenly believe that the electric door is in a closed and locked state, and then drive the electric door to rotate in the direction of the vehicle door opening for self-priming and locking, until the electric door completely closes the vehicle door opening, and the electric door's latch closes and locks the electric door. The electric door unlocking control device proposed in this application can assist the electric door unlocking operation through the electric control door module when the electric door is in an ice-breaking scenario, thereby improving the unlocking success rate of the electric door in the ice-breaking scenario.

[0008] In some embodiments, the electric door module includes a body controller, which is connected to the door lock module and the electric door module. The body controller is used to obtain user instructions. When the electric door has no handle, the user instructions include unlocking instructions and door opening instructions. After the body controller controls the electric door module to perform power-assisted operation on the electric door, it controls the electric door module to execute the door opening instruction.

[0009] In some embodiments, the electric door module includes a body controller, which is connected to the door lock module and the electric door module. The body controller is used to obtain user instructions. When the electric door has a handle, the user instructions include unlocking instructions. After the body controller controls the electric door module to perform power-assisted operation on the electric door, it controls the electric door module to shut down.

[0010] In some embodiments, the electric control door module is used to perform a door opening operation based on a first drive signal indicating that an unlocking operation is completed, and to perform a power-assisting operation on the electric door based on a second drive signal indicating that the electric door is in an ice-breaking scene, and the driving force of the second drive signal is greater than the driving force of the first drive signal.

[0011] In some embodiments, the door lock module is further used to start the suction and locking operation of the electric door during the closing process of the electric door, and to disable the suction and locking operation during the power-assisted operation of the electric door by the electric control door module.

[0012] In some embodiments, the door lock module is also used to obtain the state of the electric door after the electric control door module performs the power-assisted operation on the electric door, and control the door lock module to re-enable the suction and locking operation after the electric door is opened to the first unlocked state.

[0013] In some embodiments, the door lock module includes a door lock drive mechanism and a door control panel.

[0025] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. It should be noted that the application determines the ice-breaking scene of the application by ambient temperature is only a preferred embodiment, and is not a limitation on the method of determining the ice-breaking scene. For example, the ice-breaking scene of the application can also determine that the electric door is in the ice-breaking scene by a visual sensor, and such adjustment also falls within the protection scope of the application for determining the ice-breaking scene.

[0026] It should be understood that the terms used herein are for the purpose of describing specific example embodiments only and are not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms "a", "an", and "said" as used herein may also be meant to include plural forms. The terms "comprise", "include", and "have" are inclusive and therefore specify the presence of stated features, elements, and / or components, but do not exclude the presence or addition of one or more other features, elements, components, and / or combinations thereof.

[0027] Although the terms first, second, etc. may be used in the text to describe multiple elements, components, regions, layers and / or sections, these elements, components, regions, layers and / or sections should not be limited by these terms. These terms may only be used to distinguish one element, component, region, layer or section from another region, layer or section. Unless the context clearly indicates otherwise, terms such as "first", "second" and other numerical terms do not imply order or sequence when used in the text. In addition, in the description of this application, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0028] For ease of description, spatial relative terms can be used in the text to describe the relationship of an element or feature relative to another element or feature as shown in the figure, and these relative terms are, for example, "front", "rear", "middle", "inside", "longitudinal", "lateral", "side", "vertical", "outside", etc. Such spatial relative terms are intended to include different orientations of the mechanism in use or operation in addition to the orientation depicted in the figure. For example, if the mechanism in the figure flips, the element described as "below other elements or features" or "below other elements or features" will be subsequently oriented to "above other elements or features" or "above other elements or features". Therefore, the example term "below..." can include the orientation on and below. The mechanism can be oriented in addition (rotated 90 degrees or in other directions) and the spatial relative descriptors used in the text are interpreted accordingly.

[0029] The electric door of the embodiment of the present application can be used for vehicles such as passenger cars and engineering vehicles, and can also be used for other equipment, such as storage boxes, cabinets, etc. When the electric door is used for a vehicle, the electric door is also called the vehicle's door electric opening system, which includes the vehicle's door and a door lock module, an electric control door module and other parts installed on the door. The door can be unlocked and opened electrically or remotely, and the user does not need to manually push and pull the door to complete the unlocking and door opening and closing operations. The electric door is one of the important configuration functions of the vehicle.

[0030] The "door control panel" described in the embodiment of the present application refers to a controller that controls the door lock switch, which is provided with a basic receiving unit, a processing unit, a sending unit and a storage unit, and can control the switch of the door lock (the release and attraction of the door lock) according to instructions.

[0031] For example, during the unlocking process of a vehicle's door, the vehicle's door is unlocked by the vehicle's door lock module, and the elasticity of the door seal is used to spring the door open to a gap. When the door is frozen or blocked by other debris attached to the door, the door will be unable to spring open due to the ice constraint or the gap will not be enough to open. At this time, the door lock module will mistakenly believe that the door is in a closed state, and the door lock module will drive the door to a locked state through the self-priming motor, causing the door to fail to unlock. What's more, if the vehicle adopts a door handle-free design, if the user extends his hand to the door gap to open the door during the unlocking process, there is a risk of the door pinching the hand.

[0032] Based on the above problems, the present application provides an unlocking control device and a control method for an electric door. The specific embodiments of the present application are described in detail below in conjunction with the unlocking control device for an electric door of the first aspect of the present application.

[0033] like Figures 1 to 5As shown, the first aspect of the present application provides an unlocking control device for an electric door, the unlocking control device comprising a door lock module 20 and an electric control door module 30, the door lock module 20 being connected to the electric control door module 30, wherein the door lock module 20 is used to start the unlocking operation of the electric door according to a user instruction, and control the electric door to open to a first unlocking state after the unlocking operation is completed, the electric control door module 30 is used to start the door opening operation of the electric door after the unlocking operation is completed, and when the electric door is in an ice-breaking scene, the electric control door module 30 performs a power-assist operation on the electric door, and the power-assist operation is used to open the electric door to the first unlocking state after the unlocking operation is completed.

[0034] In this embodiment, when the electric door is not blocked, the function of the door lock module 20 is to perform the unlocking and locking operations of the electric door, while the electric control door module 30 only performs the opening and closing operations of the electric door. The two modules have their own division of labor and functions, so as to realize the automatic coordination of unlocking and opening and closing the door. That is to say, during the normal unlocking operation of the electric door, the electric control door module 30 will not intervene in the unlocking operation. The electric door can be opened with a gap of about 8mm only by the cooperation of the door lock module 20 and the door sealing strip, and when the electric door is closed to the specified position, the electric door is automatically driven to the locked position to achieve locking. However, the unlocking operation has the risk of the electric door being blocked by ice and unable to be unlocked and the risk of false triggering of self-priming. When the vehicle door has no door handle, if the electric door is unlocked only by the door lock module 20 in the scene where the door is blocked such as breaking ice, there is a risk of the user reaching out to the door gap and getting his hand pinched.

[0035] Specifically, when the vehicle is in a scenario where unlocking is obstructed, such as when breaking ice, although the door lock module 20 can drive the door latch of the electric door to open, when the electric door needs to be bounced open under the reaction force of the door sealing strip, the electric door cannot be bounced open at a specified angle or distance due to the constraint of ice or other damping forces. At this time, the door lock module 20 will mistakenly believe that the electric door is in a closed and locked condition, and then drive the electric door to rotate in the direction of the vehicle door opening for self-priming and locking, until the electric door completely closes the vehicle door opening, and the door latch of the electric door closes and locks the electric door.

[0036] Specifically, the door lock module 20 is used to unlock and lock the electric door. For example, after receiving the unlocking command from the user, the door lock module 20 can drive the door latch of the electric door to open. Since the electric door is closed to the door opening of the vehicle body by squeezing the door sealing strip, when the electric door loses the restraining force of the door latch, the electric door can be bounced open by a certain amount of gap under the reaction force of the door sealing strip, thereby completing the unlocking operation. When the door lock module 20 is blocked from performing the unlocking operation, the electric control door module 30 assists the door lock module 20 to perform the unlocking operation. Specifically, the electric control door module 30 drives the electric door to rotate to the unlocking position, that is, the electric door is moved to the unlocking position by the elastic force of the door sealing strip combined with the driving force of the electric control door module 30. After the electric door completes the unlocking operation, the electric control door module 30 drives the electric door to open to a state where the user can enter the vehicle. For example, the electric control door module 30 drives the electric door to open a preset angle or preset distance, thereby completing the door opening operation.

[0037] Specifically, user commands include unlocking the door by approaching the vehicle, unlocking the door by NFC, unlocking the door by screen, unlocking the door by voice, switching inside and outside the vehicle, and automatic door opening after APA / HAVP parking is completed.

[0038] In some embodiments, the unlocking control device also includes a control module, which is used to: obtain the ambient temperature of the electric door; obtain the real-time unlocking status of the electric door within a first preset time after the user's instruction; determine that the electric door is in an ice-breaking scene based on the ambient temperature being lower than a preset temperature value and the real-time unlocking status not satisfying a first unlocking status, and the first unlocking status includes a preset opening distance or a preset opening angle of the electric door.

[0039] In this embodiment, the specific reason why the electric door is blocked from opening is determined by the ambient temperature. If the specific reason why the electric door is blocked from opening is ice, the electric control door module 30 is used to assist in unlocking the electric door. If the specific reason why the electric door is blocked from opening is damage to components, the electric control door module 30 is not used to assist in unlocking the electric door, thereby reducing the risk of the electric door being damaged by hard door opening.

[0040] In addition, the embodiment of the present application does not limit the specific numerical value of the preset temperature value because the preset temperature value needs to be determined according to the material of the electric door. Different materials correspond to different specific numerical values ​​of the preset temperature value. The embodiment of the present application does not elaborate on the specific numerical values ​​of the preset temperature value one by one.

[0041] Furthermore, the present application determines the ice-breaking scene of the present application by ambient temperature is only a preferred embodiment, and is not a limitation on the method of determining the ice-breaking scene. For example, the ice-breaking scene of the present application can also determine that the electric door is in the ice-breaking scene by a visual sensor. This adjustment also falls within the protection scope of the present application for determining the ice-breaking scene.

[0042] In addition, the first preset time can be set to 1.5s, and the preset opening distance can be set to 8mm. When the electric door is opened by the preset opening distance, it means that the electric door has escaped the detection range of the self-priming lock, which can reduce the phenomenon of the electric door being locked by self-priming due to misoperation during the unlocking operation. At the same time, the 8mm gap of the electric door is also a comprehensive consideration of the user's operating experience and the elastic performance of the door sealing strip. When the electric door needs to be opened to a gap greater than 8mm, the structure and material of the door sealing strip need to be optimized, which not only increases the cost of the door sealing strip, but also increases the degree of wear of the door sealing strip.

[0043] When the electric door's pop-open distance is set to a gap less than 8mm, it will not only increase the burden on the door control module, but also reduce the user experience. For example, when the user wants to use his hand to hold the electric door open, due to the small gap, it is difficult for the user to hold the electric door with his hand, and he needs to use greater force to hold the electric door.

[0044] Therefore, the embodiment of the present application sets the opening distance of the electric door to 8 mm, which can not only improve the user's operating experience, but also reduce the structural and material improvements to the door sealing strip.

[0045] Furthermore, the preset opening angle corresponds to the preset opening distance. When the preset opening distance is set to 8mm, the preset opening angle is set to correspond to the 8mm spring-open distance. When the electric door is opened at the preset opening angle, it means that the electric door has escaped the detection range of the self-priming lock, reducing the phenomenon of the electric door being self-priming and locked due to misoperation during the unlocking operation. At the same time, setting the electric door to the preset spring-opening angle is also a comprehensive consideration of the user's operating experience and the elastic performance of the door sealing strip. The specific implementation method is similar to the implementation method of the preset opening distance.

[0046] In addition, the detection method of the preset opening angle is different from the detection method of the preset opening distance. The preset opening angle is detected by an angle sensor, while the preset opening distance is detected by a distance sensor. The detection accuracy of the preset opening angle in this embodiment is greater than the detection accuracy of the preset opening distance. However, the detection of the preset opening distance is more direct, which is directly reflected in the correspondence with the detection range of the self-priming lock and the correspondence with the user's operating experience. Both have their own advantages and can be reasonably set according to the actual usage scenario.

[0047] In addition, it should be noted that the embodiments of the present application do not limit the control module because the control module can be a body controller 10, or a door control panel 22 of a door lock module 20, or a door controller 32 of an electric door module 30, all of which belong to the protection scope of the control module of the embodiments of the present application. The preferred embodiments of the control module will be described in detail below.

[0048] like Figure 5 As shown, in some embodiments, the electric door module 30 includes a body controller 10, which is connected to the door lock module 20 and the electric door module 30. The body controller 10 is used to obtain user instructions. When the electric door has no handle, the user instructions include unlocking instructions and door opening instructions. After the body controller 10 controls the electric door module 30 to perform the power-assisted operation on the electric door, it controls the electric door module 30 to execute the door opening instruction.

[0049] In this embodiment, the embodiment of the present application proposes that when the electric door has no handle, the body controller 10 assists the door lock module 20 to perform the unlocking operation through the electric door module 30. Specifically, the electric door module 30 drives the electric door to rotate and moves to the first unlocking state, or in other words, the electric door moves to the first unlocking state through the elastic force of the door sealing strip combined with the driving force of the electric door module 30. When the electric door completes the unlocking operation, the electric door module 30 drives the electric door to open to a state where the user can enter the car, that is, the electric door opens to the second unlocking state, for example, the electric door module 30 drives the electric door to open to a preset angle or preset distance, thereby completing the door opening operation.

[0050] Specifically, the door lock module 20 and the electric door module 30 are both electrically connected to the body controller 10, wherein the body controller 10 is used to send user instructions to the door lock module 20, and the door lock module 20 performs an unlocking operation of the electric door according to the user instructions, and is used to obtain an ice-breaking unlocking operation signal when the door lock module 20 performs an ice-breaking unlocking operation, and control the electric door module 30 to assist the electric door in performing an unlocking operation according to the ice-breaking unlocking operation signal.

[0051] Specifically, the body controller 10 includes an MPU control module and an MCU control module. The MPU control module refers to the vehicle's microprocessor, which is mainly used to perform the "processing" function and has high requirements for data processing and computing capabilities; the MCU control module refers to the body microcontroller, which is used to complete "control" related tasks and respond according to external signal stimuli; the MPU control module and the MCU control module are collectively referred to as the body controller 10.

[0052] The embodiment of the present application centrally controls the door lock module 20 and the electric door module 30 through the body controller 10, which can improve the safety level of the electric door and reduce the error rate of directly executing user instructions through the door lock module 20 and the electric door module 30.

[0053] In some embodiments, the electric door module 30 includes a body controller 10, which is connected to the door lock module 20 and the electric door module 30. The body controller 10 is used to obtain user instructions. When the electric door has a handle, the user instructions include unlocking instructions. After the body controller 10 controls the electric door module 30 to perform a power-assisted operation on the electric door, it controls the electric door module 30 to shut down.

[0054] In this embodiment, the embodiment of the present application proposes that when the electric door has a handle, the body controller 10 assists the door lock module 20 to perform an unlocking operation through the electric door module 30. Specifically, the electric door module 30 drives the electric door to rotate and moves to a first unlocking state. In other words, the elastic force of the door sealing strip combined with the driving force of the electric door module 30 moves the electric door to the first unlocking state, and then the user is required to pull the electric door open to the second unlocking state by the handle. For example, the user pulls the electric door open by the handle to open a preset angle or a preset distance to complete the door opening operation.

[0055] like Figure 5 As shown, in some embodiments, the electric door module 30 performs a door opening operation according to a first drive signal indicating that an unlocking operation is completed, and performs a power-assisting operation on the electric door according to a second drive signal indicating that the electric door is in an ice-breaking scene, wherein the driving force of the second drive signal is greater than the driving force of the first drive signal.

[0056] In this embodiment, the electric door module 30 is used to control the opening and closing of the electric door, and specifically includes a door drive mechanism 31 and a door controller 32. The door drive mechanism 31 is also called an electric door limiter. The electric door limiter drives the opening and closing angle or opening and closing amplitude of the door through a driving motor according to the user's door opening and closing instructions, thereby reducing the phenomenon of the electric door opening and closing angle being too large or too small. In other words, the electric door limiter can not only play the role of automatic opening and closing of the door, but also reduce the phenomenon of the electric door opening angle being too large or closing angle being too small to impact the vehicle body.

[0057] Furthermore, the embodiments of the present application can improve the success rate of the power-assisted unlocking operation of the electric control door module 30 and improve the success efficiency of the unlocking operation by improving the driving force of the electric control door module 30 during the power-assisted unlocking operation, thereby improving the user's operating experience. Specifically, by optimizing the driving force of the electric control door module 30, the driving force of the electric control door module 30 in the ice-breaking obstruction scenario is different from the driving force in the normal door opening scenario. For example, the driving force of the electric control door module 30 in the normal door opening condition is about 20N, and the driving force of the electric control door module 30 in the ice-breaking obstruction scenario can be increased to 60N to 80N.

[0058] In addition, when the output power of the electric door module 30 is constant, increasing the driving force of the electric door module 30 means reducing the speed of the electric door module 30, so as to achieve the effect of slowly unlocking the electric door and reduce the phenomenon of accidentally injuring or colliding with the user due to unlocking and opening and closing the electric door too quickly.

[0059] like Figure 5 As shown, in some embodiments, the door lock module 20 is also used to start the suction and locking operation of the electric door during the closing process of the electric door, and to disable the suction and locking operation during the power-assisted operation of the electric door by the electric control door module 30.

[0060] In this embodiment, the door lock module 20 is not only used to control the unlocking of the electric door, but also used to control the self-priming locking of the electric door. The door lock module 20 specifically includes a door control panel 22 and a door lock drive mechanism 21. The door lock drive mechanism 21 includes an unlocking motor and a self-priming motor. The unlocking motor is used to drive the door latch of the electric door to open, so that the electric door can be driven by an elastic element (such as an elastic seal) to bounce a certain distance or angle. The self-priming motor can drive the electric door to close to a locked state during the closing process of the electric door when the distance between the electric door and the vehicle body is less than a preset opening distance or the opening angle of the electric door is less than a preset opening angle, thereby achieving the purpose of "self-priming" door closing and locking, and reducing the phenomenon of the electric door not being completely closed.

[0061] In order to reduce the possibility that the door lock module 20 mistakenly believes that the electric door is in a closed and locked condition due to obstruction of the electric door during the unlocking process of the electric door, an embodiment of the present application proposes disabling the suction and locking operation during the unlocking process of the electric door, that is, disabling the self-priming motor of the door lock module 20 during the unlocking process of the electric door, so as to reduce the phenomenon of users' hands being pinched when they put their hands into the gap of the electric door.

[0062] like Figure 5As shown, in some embodiments, the door lock module 20 is also used to obtain the state of the electric door after the electric control door module 30 performs a power-assisted operation on the electric door, and control the door lock module 20 to re-enable the suction and locking operation after the electric door is opened to the first unlocked state.

[0063] In this embodiment, the self-priming motor of the door lock module 20 can drive the electric door to close to a locked state during the closing process of the electric door when the distance between the electric door and the vehicle body is less than the preset opening distance or the opening angle of the electric door is less than the preset opening angle, thereby achieving the purpose of "self-priming" door closing and reducing the phenomenon of the door not being completely closed.

[0064] Specifically, the electric control door module 30 assists in the unlocking operation successfully, which specifically includes the electric control door module 30 assisting in the unlocking operation successfully within the preset time, and the electric door can continue to remain unlocked within the preset time after the unlocking operation is successful. In other words, when the electric door opens to the preset pop-up angle, the door lock module 20 can automatically restore the self-priming function, thereby not affecting the subsequent normal operation of the electric door.

[0065] like Figure 5 As shown, in some embodiments, the door lock module 20 includes a door lock drive mechanism 21 and a door control panel 22. The door control panel 22 controls the door lock drive mechanism 21 to perform unlocking operations and closing and locking operations, and sends the signal of the ice breaking scene to the electric control door module 30.

[0066] In this embodiment, the door lock module 20 is used to control the unlocking and locking of the electric door, and specifically includes a door control panel 22 and a door lock drive mechanism 21. The door lock drive mechanism 21 includes an unlocking motor and a self-priming motor. The unlocking motor is used to drive the door latch of the vehicle door to open, so that the vehicle door can be driven by an elastic element (such as an elastic seal) to bounce a certain distance or angle. The self-priming motor can drive the vehicle door to close to a locked state during the closing process of the vehicle door when the distance between the vehicle door and the vehicle body is less than a preset opening distance or the opening angle of the vehicle door is less than a preset opening angle, thereby achieving the purpose of "self-priming" door closing and reducing the phenomenon of the vehicle door not being completely closed.

[0067] like Figure 5 As shown, in some embodiments, the electric door module 30 includes a door drive mechanism 31 and a door controller 32. The door controller 32 obtains an ice-breaking scene signal and controls the door drive mechanism 31 to perform a door opening operation or a power-assisting operation on the electric door.

[0068] In this embodiment, the electric door module 30 is used to drive the opening and closing of the electric door, and specifically includes a door drive mechanism 31 and a door controller 32. The door drive mechanism 31 is also called an electric door limiter. The electric door limiter can drive the opening and closing angle or opening and closing amplitude of the door through a driving motor according to the user's door opening and closing instructions, thereby reducing the phenomenon of the door opening and closing angle being too large or too small. In other words, the electric door limiter can not only play the role of automatic opening and closing of the door, but also reduce the phenomenon of the door opening angle being too large or the closing angle being too small to impact the vehicle body.

[0069] A second aspect of the present application provides a vehicle, the vehicle comprising an unlocking control device for an electric door according to the first aspect of the present application.

[0070] In this embodiment, the vehicle provided by the second aspect of the present application has all the technical effects of the unlocking control device of the first aspect of the present application, which will not be repeated here.

[0071] like Figure 1 and Figure 5 As shown, the third aspect of the present application provides an unlocking control method for an electric door, the unlocking control method comprising: controlling the door lock module 20 of the electric door to start an unlocking operation according to a user instruction; determining whether the electric door is in an ice-breaking scene; when the electric door is not in an ice-breaking scene, controlling the electric control door module 30 to start an opening operation of the electric door after the unlocking operation is completed; when the electric door is in an ice-breaking scene, controlling the electric control door to perform a power-assist operation on the electric door, and the power-assist operation acts on the electric door to enable it to open to a first unlocked state after the unlocking operation is completed.

[0072] In this embodiment, the unlocking control method of the electric door proposed in the present application can assist the electric door to perform the unlocking operation through the electric control door module 30 when the door lock module 20 is blocked from performing the unlocking operation, thereby improving the unlocking success rate of the electric door in the unlocking scenario, especially improving the unlocking success rate of the electric door in the ice-breaking unlocking scenario.

[0073] The following describes in detail the door obstruction scenario of the present application through two embodiments using an ice-breaking scenario, and the two embodiments respectively describe not enabling the body controller 10 and enabling the body controller 10 .

[0074] like Figure 2 and Figure 5 As shown, this embodiment is an ice-breaking scenario in which the vehicle body controller 10 is not enabled, and only the door lock module 20 and the electric control door module 30 are relied upon to control the unlocking and opening and closing of the electric door.

[0075] When the user triggers the unlocking and door opening action, after the door lock slightly open signal jumps, the timing is 3s, the door lock is in the electric release state, and it is judged whether the door lock is fully opened within 3s. When the door lock is fully opened, the door lock is electrically released successfully, and the electric release motor is reset; when the door lock is not fully opened and enters the ice-breaking unlocking working condition, the electric control door module 30 assists the door lock module 20 to perform the unlocking operation according to the ice-breaking unlocking signal. At the same time, the door lock module 20 disables the self-closing function of the electric door. The electric control door module 30 receives the signal to enter the "ice-breaking mode" and controls the electric door to open at a certain angle by default, which can support the minimum angle or full opening of the electric door. If the electric door is fully opened within 1.5s and the opening exceeds a certain angle, the self-closing function of the door lock module 20 is restored. The electric door is opened at a certain angle, including a position greater than the semi-locked state (about 8mm) of the electric door, and can also be a preset position larger than the semi-locked state.

[0076] In the process where the door lock module 20 and the electric control door module 30 jointly assist in pushing away the ice layer attached to the electric door, the door lock module 20 simultaneously disables the self-closing function of the electric door. When the opening of the electric door exceeds 2° or the electric door returns to the closed and locked state, the door lock module 20 restores the self-closing function of the electric door. Specifically, when the opening of the electric door exceeds 2°, it means that the electric door can be opened normally and the electric door has overcome the situation of being blocked from unlocking. At this time, the door lock module 20 re-enables the self-closing function of the electric door, which can ensure that the electric door can be closed and locked normally in the closed door condition.

[0077] In this example:

[0078] 1) The electric door module 30 adds control logic for the power unlocking operation. In the ice-breaking scenario, the driving force of the power unlocking operation of the electric door module 30 is greater than the driving force of the door opening operation.

[0079] 2) The door lock module 20 adds control logic for self-closing disabling and recovery, and adds an ice-breaking status signal.

[0080] like Figure 3 and Figure 5 As shown, this embodiment is an ice-breaking scenario in which the vehicle body controller 10 is activated.

[0081] After the body controller 10 receives the signal to enter the "ice-breaking mode", it controls the electric door to open at a certain angle by default, and can support opening at the minimum angle or fully opening; the body controller 10 gives a door opening angle signal to the electric door module 30, and the electric door module 30 determines the door opening prerequisites of the electric door (for example, whether the electric door is in a thermal protection state, whether the electric door triggers the anti-play mode). When the electric door meets the door opening prerequisites, the electric door module 30 assists the door lock module 20 to perform the unlocking operation.

[0082] In this embodiment: the body controller 10 controls the electric door module 30 to assist the door lock module 20 in performing the unlocking operation. The electric door module 30 only acts as an actuator. The overall control logic is relatively reasonable, and the body controller 10 uses a screen door opening link, which meets the functional safety requirements, and the safety level can reach ASIL B.

[0083] like Figure 4 and Figure 5 As shown, this embodiment is an ice breaking scene in which the vehicle body controller 10 is enabled. Figure 3 The difference between the embodiments is that the door is unlocked and opened according to the user's instructions, without distinguishing between the ice-breaking door opening scene and the normal door opening scene.

[0084] After the body controller 10 receives the "ice-breaking mode" signal, some scenarios can support controlling the door opening according to the user's intention before breaking the ice. The specific implementation scenarios include: voice inside and outside the car, screen, buttons inside and outside the car, unlocking near the car (digital key interface can be added later), NFC unlocking and opening the door, APA (automatic parking), HAVP (autonomous learning parking), and actively controlling the door opening after parking. The signals of these scenarios can be realized by adding signal communication.

[0085] In this example:

[0086] 1) It does not involve changes to the electric door module 30. If you want to change the opening angle of the electric door in the ice-breaking mode later, you do not need to go through the supplier.

[0087] 2) When the user triggers the door opening action, the above functions can only be realized when the body controller 10 is in the awake state, that is, the technical problem of not being able to support opening the door by swiping the NFC card for the first time or pressing the external switch in the dormant state is solved.

[0088] 3) The main control logic for unlocking and opening the door is in the body controller 10, which solves the technical problem of being unable to clearly identify the door opening scenario at this time. If there is no body controller 10, only a rough judgment can be made through the signal, and there is a risk of misidentification in the scenarios that are conditionally supported. For example, without the body controller 10, there is no fault identification capability. After the user triggers the door opening, the door lock is unlocked successfully. However, the door lock module 20 mistakenly sends an ice-breaking signal. At this time, the electric door module 30 will still assist in the unlocking operation. Through the intervention of the body controller 10, the above-mentioned risks will not exist.

[0089] The fourth aspect of the present application provides a computer program product, including a computer program / instructions, which implements the unlocking control method of the electric door as the third aspect of the present application when the computer program / instructions are executed.
