Description

Technical Field

[0001] The present application relates to the field of vehicle control technology, and more specifically, to a vehicle control method, a vehicle control method device, a vehicle, and a computer-readable storage medium in the field of vehicle control technology. Background Art

[0002] With the rapid development of vehicle technology, new energy vehicles have gradually become an important means of transportation for people. New energy vehicles use batteries as energy. When using new energy vehicles, if the user does not charge the battery for a long time, or the vehicle has a long mileage, the battery power in the vehicle may be too low, causing the battery to be in a low-power state. When the battery is in a low-power state, the door may not respond to the user's unlocking or locking operation, resulting in the user being unable to control the door and unable to use the vehicle normally. Summary of the invention

[0003] The present application provides a vehicle control method, a vehicle control method device, a vehicle and a computer-readable storage medium. The method can ensure the normal unlocking or locking of the vehicle doors when the battery of the vehicle is in a low-power state, thereby improving the convenience of users in using the vehicle.

[0004] In a first aspect, a vehicle control method is provided, the method comprising: monitoring a current battery status of a vehicle; if the current battery is in a low-power state and an unlocking or locking operation of a door in the vehicle is detected; activating a backup battery of the vehicle; and controlling the door to be unlocked or locked by the backup battery.

[0005] In an embodiment of the present application, the vehicle's backup battery can be enabled, and the vehicle doors can be unlocked or locked by controlling the backup battery. Since the vehicle's backup battery is enabled to control the doors to be unlocked or locked when it is monitored that the vehicle's current battery status is in a low-power state and an unlocking or locking operation on the doors is detected, the backup battery can be used to ensure that the doors can be controlled to respond to the user's unlocking or locking operation when the vehicle's battery is in a low-power state, so that the doors can be unlocked or locked normally, thereby improving the convenience of users using the vehicle.

[0006] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: sending a prompt message, wherein the prompt message is used to prompt the user that the current battery is in the low-power state and the vehicle door is in an unlocked state or a locked state.

[0007] In an embodiment of the present application, a prompt message can be sent when the battery of the vehicle is in a low-power state; since the prompt message that the battery of the vehicle is in a low-power state is sent to the user, the user can understand the battery status and door status of the vehicle, so that the user can charge the battery in time when the battery status is low-power; and when the door is in an unlocked state or a locked state, the user can accurately perform the corresponding operation, for example, when the door is in an unlocked state, the user can perform the locking operation, and when the door is in a locked state, the user can perform the unlocking operation.

[0008] In combination with the first aspect and the above-mentioned implementation manners, in some implementation manners of the first aspect, the low-battery state is that the current battery power value is less than or equal to a preset threshold.

[0013] In combination with the first aspect and the above-mentioned implementation methods, in some implementation methods of the first aspect, the method also includes: obtaining at least one locking result of the vehicle door; if the at least one locking result includes a locking failure result, outputting a warning message; wherein the warning message is used to prompt the user that the vehicle door has failed to lock.

[0014] In an embodiment of the present application, if at least one locking result includes a locking failure result, a warning message is output; wherein the warning message is used to prompt the user that the door locking has failed; since when the door locking failure result is obtained, a warning message to prompt the user of the locking failure can be output, the user can lock the door again after obtaining the warning message, or repair the door lock in time when a door lock fails.

[0015] In combination with the first aspect and the above-mentioned implementations, in some implementations of the first aspect, the method further includes: obtaining a power status of the vehicle; if the power status is a power-off and power-on status, controlling the motor to reset.

[0016] In an embodiment of the present application, if the power status is a power-off and power-on status, the motor is controlled to be reset; since the motor in the door is controlled to be reset when the power status of the vehicle is obtained to be a power-off and power-on status, damage to the motor can be avoided when the vehicle is powered off and then powered on; through the solution of the present application, effective protection measures can be ensured for the motors in the vehicle.

[0034] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0035] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0036] Figure 1 It is a schematic diagram of a scene of vehicle battery power display provided in an embodiment of the present application.

[0037] For example, Figure 1 As shown in (a), Figure 1 (a) includes a vehicle 110. The vehicle 110 may include a dashboard 111, and the dashboard 111 may include a display mark 112 of the battery power in the vehicle 110. Figure 1 As can be seen from (a) in FIG. 1 , the battery power display mark 112 is composed of 5 squares, and each square can represent 20% of the battery power. Figure 1 As shown in (b) in FIG. 1 , when the battery power is 100%, all five squares in the battery power display mark 112 are filled; Figure 1 As shown in (c) in FIG. 1 , when the battery power is 60%, the three squares from bottom to top in the battery power display mark 112 will be in a filled state.

[0038] When using new energy vehicles, if the user does not charge the battery for a long time or the vehicle has a long mileage, the battery power in the vehicle may be too low, causing the battery to be in a power-deficient state; for example, Figure 1As shown in (a), the battery power is 20%. When the battery is in a low power state, the door may not respond to the user's unlocking or locking operation, resulting in the user being unable to control the door and thus being unable to use the vehicle normally.

[0039] In order to solve the above problems, the present application provides a vehicle control method, which can ensure the normal unlocking or locking of the vehicle doors when the vehicle's battery is in a low-power state, thereby improving the convenience of users in using the vehicle.

[0040] Figure 2 It is a flow chart of the vehicle control method provided in an embodiment of the present application.

[0041] For example, Figure 2 As shown, the method 200 includes the following implementation process:

[0042] S210, monitoring the current battery status of the vehicle.

[0043] The battery status may include whether the battery is fully charged (e.g. Figure 1 (b) in the figure), non-fully charged state (such as Figure 1 (c) in the figure), low power state (such as Figure 1 (a) in the figure.

[0044] Exemplarily, the low-battery state is when the battery value of the battery in use of the vehicle (which can be recorded as the "current battery") is less than or equal to a preset threshold.

[0045] The setting of the preset threshold value can avoid the battery loss of the vehicle. Since the battery may be damaged when the battery power is too low, the preset threshold value cannot be set too small. The preset threshold value can be set to 50% or 40%, or it can be set according to user needs. The embodiment of the present application does not limit this.

[0046] For example, when the current battery power of the vehicle is monitored to be 20%, which is less than the preset threshold value of 50%, it indicates that the battery is in a low-power state.

[0047] Exemplarily, the battery status of the vehicle currently being used can be detected by a battery status monitoring module provided in the vehicle, and the detected battery status (e.g., low-battery status) can also be transmitted to a controller area network (CAN), thereby facilitating other modules in the vehicle (e.g., an information sending module or an early warning module) to obtain the battery status.

[0048] S220: If the battery is currently in a low-power state, and an unlocking operation or a locking operation of a door in the vehicle is detected.

[0049] Among them, the unlocking operation refers to an operation that can send an instruction to control the door to unlock (which can be recorded as an "unlocking instruction"), and the locking operation refers to an operation that can send an instruction to control the door to lock (which can be recorded as a "locking instruction"). In addition, the unlocking operation or the locking operation can be a user touching the outside door handle, or a user touching the inside door handle, or a user touching or pressing a control button on the vehicle key for unlocking or locking the door, which is not limited in the embodiments of the present application. For example, when the door is in a locked state, when the user unlocks the door from outside the vehicle, the door can be unlocked by touching the unlock button on the outside door handle.

[0050] Exemplarily, the body domain controller in the vehicle can obtain the current battery status of the vehicle in the CAN network. If the current battery status of the vehicle is obtained to be in a low-power state (i.e., the battery power is 20%), and when the user's unlocking or locking operation on the door is detected, S230 can be executed.

[0051] S230, activating the backup battery of the vehicle, and controlling the vehicle doors to unlock or lock by the backup battery.

[0052] The backup battery of the vehicle may have the function of replacing the current battery of the vehicle to power the vehicle. For example, the backup battery may be used as a power source for unlocking or locking the doors of the vehicle.

[0053] For example, if it is detected that the current battery status of the vehicle is in a low-power state and the user unlocks or locks the door, the body domain controller can send a control signal to the battery control module of the vehicle to start the backup battery, so that the battery control module of the vehicle enables the backup battery of the vehicle and completes the power switching.

[0054] Furthermore, if the backup battery of the vehicle is successfully activated, the backup battery can be used to control the unlocking or locking of the vehicle. By using the backup battery to power the vehicle, when the current battery of the vehicle is in a low-power state, the backup battery can be used to ensure that the door can be controlled to respond to the user's unlocking or locking operation, so that the door can be unlocked or locked normally, thereby improving the convenience of the user in using the vehicle.

[0055] Exemplarily, the above method further includes: sending a prompt message.

[0056] The prompt information may be used to prompt the user that the current battery is in a low-power state and the door is in an unlocked or locked state. Also, the prompt information may include content for switching the vehicle power source from the current battery to the backup battery. It should be understood that the user refers to a user who can receive the prompt information, for example, a user associated with the terminal and the vehicle, and does not refer to a specific user.

[0057] Optionally, when the current battery status of the vehicle is in a low-power state, the vehicle power source is switched from the current battery to the backup battery, and the information sending module in the vehicle can send a text message to a terminal associated with itself to remind the user that the current battery of the vehicle is in a low-power state, and / or the power source of the vehicle is switched to the backup battery, and the current status of the door can also be sent to the user, for example, the door is in an unlocked state or a locked state.

[0058] By sending prompt information about the vehicle's current low battery and door status to the user, the user can understand the vehicle's battery status and door status, so that the user can charge the battery in time when the battery status is low; and when the door is in an unlocked state or a locked state, the user can accurately perform the corresponding operation, for example, when the door is in an unlocked state, the user can perform the locking operation, and when the door is in a locked state, the user can perform the unlocking operation.

[0059] It should be understood that sending a prompt message to the user via text message is only one implementation method in the embodiment of the present application. The vehicle can also make a call to the terminal associated with itself to send a prompt message to the user; or, the vehicle can also display a prompt message to the user on the vehicle computer that the current battery is in a low-power state. The embodiment of the present application does not limit this.

[0060] Optionally, if the current battery of the vehicle is not in a low-power state (eg, not fully charged), no prompt information about the current battery status is sent to the user.

[0061] exist Figure 2 In the provided method 200, when it is monitored that the current battery state of the vehicle is in a low-power state and an unlocking or locking operation of the vehicle door is detected, the vehicle's backup battery can be enabled, and the vehicle door can be controlled to be unlocked or locked using the backup battery. When the vehicle's battery is in a low-power state, the backup battery can be used to ensure that the vehicle door can be controlled to respond to the user's unlocking or locking operation, so that the vehicle door can be unlocked or locked normally, avoiding the inability to unlock or lock the vehicle door due to low battery of the vehicle, thereby improving the convenience of users using the vehicle.

[0062] The above method is used to put the power supply of the vehicle in a normal state. When the power supply of the vehicle is normal, the following method can be executed to lock the vehicle doors.

[0063] In one possible implementation, the state of a door in the vehicle is detected; if the state of the door changes from a first open state to a second open state, the motor in the door is controlled to be in a powered state; if the motor is in a powered state, the door is controlled to be locked.

[0064] The second open state is used to indicate that the angle between the door and the side skirt of the vehicle is less than a preset angle threshold.

[0065] Figure 3 It is a schematic diagram of the door state change provided in an embodiment of the present application.

[0066] For example, Figure 3 As shown, Figure 3 The three states of the door are included. Figure 3 As shown in (a) in the figure, the angle between the vehicle door and the center side skirt panel of the vehicle body is A, and the angle A can be greater than half of the maximum angle between the vehicle door and the center side skirt panel of the vehicle body (which can be recorded as the "first open state"), and the user can smoothly enter and exit the vehicle when the vehicle door is in the first open state.

[0067] like Figure 3 As shown in (b) in the figure, the angle between the door and the center side skirt panel of the vehicle body is B, and the angle B can be less than or equal to half of the maximum angle between the door and the center side skirt panel of the vehicle body, and greater than 0° (which can be recorded as the "second open state"). In addition, if the door is in the second open state, the user cannot enter and exit the vehicle normally due to the small opening angle of the door.

[0068] like Figure 3 As shown in (c), the angle between the door and the side skirt panel of the vehicle body is 0°, that is, the door is in a locked state.

[0069] For example, since the maximum angle between the door and the side skirt of the vehicle body can be 70°, when the door opening angle is 70°, it can be said that the door is in a fully open state; if the door opening angle is 35°, it can be said that the door is in a half-open state, and the half-open state can indicate that the door is neither fully open nor fully closed (i.e., the door opening angle is less than 70° and greater than 0°). The maximum opening angle of the door is related to the vehicle model, and the embodiments of the present application do not limit this.

[0070] For example, the current state of the door can be detected by the door lock control module in the door. If it is detected that the state of the door changes from a fully open state to a half-open state, the motor in the door can be controlled to be energized, so that the door is in a self-priming state, so as to control the door to complete self-priming locking.

[0071] The motor can be used to control the door to automatically close from the second open state (eg, half-open state) to the locked state. Also, the self-priming state refers to the process in which the door automatically closes from the second open state to the locked state.

[0072] Optionally, if the user directly closes the vehicle door from a fully open state to a locked state, the door lock control module may not perform self-priming locking when detecting this process.

[0073] In the embodiments of the present application, the user can trigger the self-priming lock of the car door with a very small force, so that the locking process of the car door can be carried out automatically without the user manually closing the car door, thereby improving the intelligence of the car door closing and improving the user experience; and, when the user is an elderly person or a child, he or she does not have enough strength to close the car door smoothly; or when the user has a lot of things in his or her hands and it is inconvenient to free up his or her hands to close the car door, he or she only needs to apply a very small force to close the car door to trigger the self-priming lock of the car door, making closing the car door more labor-saving and convenient, thereby providing convenience for the user.

[0074] In a possible implementation, during the process of controlling the vehicle door to be locked, in response to an unlocking instruction, the vehicle door is controlled to be adjusted to a first open state.

[0075] For example, in the process of controlling the vehicle door to self-prime from a second open state (for example, a half-open state) to a locked state, if the user successfully triggers the unlocking command of the vehicle door by pressing the control button on the outside handle of the vehicle door, the door lock control module receives the unlocking command and detects that the self-priming switch of the vehicle door is turned on. In response to the unlocking command, the door can be controlled to adjust from the current state to the first open state (for example, a fully open state).

[0076] For example, when the door is half-open (e.g. Figure 3 (b)) The self-priming is in a locked state (for example, Figure 3 In the process of (c) in FIG. 1 , if an unlocking command triggered by a user is received, the self-priming process of the door is interrupted, and the door is controlled to be adjusted from the current state to the fully open state (for example, Figure 3 (a) in the figure.

[0077] Optionally, after the vehicle door is locked successfully, when the door lock control module receives an unlocking command triggered by the user, it may also respond to the unlocking command and control the vehicle door to adjust from the locked state to the first open state.

[0078] In an embodiment of the present application, during the automatic locking process, the vehicle door can respond to an unlocking command, interrupt the automatic locking process of the vehicle door, and unlock the vehicle door; this avoids the vehicle having to complete the automatic locking process and then execute the unlocking command after receiving the unlocking command, thereby saving the time for unlocking the vehicle door and reducing the energy consumption used by the vehicle in completing the automatic locking process after receiving the unlocking command.

[0079] Figure 4 It is a schematic diagram of the process of the door self-priming provided in the embodiment of the present application.

[0080] For example, Figure 4 As shown, the method 400 includes the following implementation process:

[0081] S410, obtaining the state of the vehicle door.

[0082] Exemplarily, the current state of the vehicle door may be acquired through the door lock control module, for example, a locked state or a self-priming state, etc. After acquiring the state of the vehicle door, S420 may be executed to judge the acquired state.

[0083] S420, determine whether the vehicle door is in a self-priming state; if so, execute S430; if not, execute S440.

[0084] For example, if it can be determined through judgment that the vehicle door is in a non-self-priming state, for example, a locked state, S410 can be continued to be executed to continuously obtain the state of the vehicle door.

[0085] For example, if it can be determined through judgment that the vehicle door is in a self-priming state, S430 is executed.

[0086] S430, determine whether the unlock instruction is triggered; if not, execute S440; if so, execute S450.

[0087] Exemplarily, if the unlock instruction is not triggered, S440 may be executed.

[0088] S440, locking is successful.

[0089] Exemplarily, when the vehicle door is in the self-priming state, if the unlocking command of the vehicle door is not triggered, the vehicle door can complete the self-priming and can be locked successfully if there is no malfunction in the door lock.

[0090] Exemplarily, if the unlocking command of the vehicle door is triggered, S450 may be executed.

[0091] S450, determine whether the self-priming reset switch is disconnected; if so, execute S470; if not, execute S440.

[0092] Exemplarily, when the vehicle door is in a self-priming state and the unlocking command is triggered, if the self-priming reset switch in the vehicle door is not disconnected, that is, the self-priming reset switch is in the on state, S440 can be executed; and, the implementation method of S440 is described above and will not be repeated here.

[0093] Exemplarily, after the vehicle door is locked successfully, S460 may be executed.

[0094] S460, determine whether the unlock instruction is triggered; if so, execute S470.

[0095] Exemplarily, if the door unlocking command is triggered, S470 may be executed.

[0096] For example, if the unlocking command of the vehicle door is not triggered, the vehicle door can be controlled to remain in a locked state.

[0097] S470, electrolysis starts.

[0098] For example, after the vehicle door is successfully locked, if it is detected that the unlocking command is triggered again, the door electrolysis can be controlled to start and the vehicle can be unlocked.

[0099] Exemplarily, when the vehicle door is in a self-priming state and the unlocking command is triggered, if the self-priming reset switch in the vehicle door is disconnected, S470 can also be executed; and, the implementation method of S470 is described above and will not be repeated here.

[0100] In a possible implementation, after the vehicle door is locked, at least one locking result of the vehicle door may be obtained; if at least one locking result includes a locking failure result, a warning message is output.

[0101] Among them, the locking result refers to whether the pawl switch, door status switch and ratchet switch in the vehicle door are in the on state or the off state; when the pawl switch, door status switch and / or ratchet switch are in the on state, it means that the locking has failed (which can be recorded as "locking failure result"); or, when the pawl switch, door status switch and ratchet switch are all in the off state, it means that the locking is successful.

[0102] Among them, the early warning information is used to remind the user that the door locking fails.

[0103] Exemplarily, since the vehicle door locking is performed by the pawl switch, the door status switch and the ratchet switch, the locking result of the pawl switch, the door status switch or the ratchet switch can be obtained. When the pawl switch, the door status switch and / or the ratchet switch are obtained to be in the on state, the locking result of the vehicle door includes a locking failure result, indicating that the vehicle door locking has failed or the door lock in the vehicle door is faulty.

[0104] Optionally, if the door fails to lock or the door lock fails, the warning module in the vehicle can send a text message to a terminal associated with itself to remind the user that the door fails to lock or the door lock fails. By sending the warning information of the door failure or the door lock failure to the user, the user can lock the door again after obtaining the warning information, or repair the door lock in time when the door lock fails.

[0105] It should be understood that sending warning information to users via text messages is only one implementation method in the embodiments of the present application. The vehicle can also make a call to the terminal associated with itself to send warning information to the user; or, the vehicle can also display warning information of door locking failure or door lock malfunction to the user on the vehicle computer, which is not limited to the embodiments of the present application.

[0106] Optionally, if the pawl switch, the door status switch and the ratchet switch are all in the disconnected state, it means that the vehicle door is locked successfully, and no warning information is sent to the user.

[0107] When multiple doors are locked, the current state of the vehicle can be obtained. When it is obtained that the vehicle is in a parking state and the vehicle is turned off, it can also detect whether there is a user in the vehicle through image detection and pressure detection. When it is detected that there is a user in the vehicle, it means that there is a legacy user in the vehicle, and the doors are controlled not to be locked, and a warning message is sent to the user terminal to remind the user that there is a legacy user in the vehicle, which can avoid locking the legacy user in the vehicle for a long time and threatening his life. Alternatively, when it is detected that there is no user in the vehicle, the doors are controlled to be locked successfully.

[0108] In one possible implementation, one or more current images of the vehicle's interior compartment (which may be referred to as "internal images") can be obtained through an image acquisition device (camera or smart screen) provided in the vehicle. After obtaining the internal images, the image acquisition device can transmit the internal images to an image processing device provided in the vehicle, and start the image processing device to perform intelligent recognition on the obtained internal images to determine whether there is a user in the vehicle.

[0109] Optionally, when it is determined through intelligent recognition that there is no user image in the interior image, it can be determined that there is no user in the vehicle.

[0110] Optionally, when one or more user images are found in the internal image through intelligent recognition, it indicates that there are users in the vehicle.

[0111] Among them, the image acquisition device in the vehicle can periodically (for example, 30S or 1 minute) acquire the interior image of the vehicle. When it is intelligently identified that there is a user in the vehicle, the interior image of the vehicle can be periodically acquired until it is intelligently identified that there is no user image in the acquired interior image.

[0112] In another possible implementation, a vital sign detection device, such as a millimeter-wave radar, provided in the vehicle may be used to detect whether the vehicle has vital signs; if vital signs are detected in the vehicle by the millimeter-wave radar, it may be determined that there is a user in the vehicle.

[0113] Furthermore, a cyclic detection method can be used to avoid misjudgment when detecting whether there are signs of life in the vehicle. When the number of detections reaches a preset number (for example, 5 times) and no signs of life are detected in the vehicle each time, it can be determined that there is no user in the vehicle. Alternatively, when the number of detections reaches 5 times, if there are one or more signs of life detected in the vehicle, it can be determined that there is a user in the vehicle.

[0114] In the embodiment of the present application, since millimeter-wave radar detection technology has the advantages of strong penetration ability, high resolution, strong anti-interference ability and high detection accuracy, the use of millimeter-wave radar to detect whether there is a user in the vehicle can make the detection result more accurate, avoiding misjudgment, detecting inanimate objects such as bags, fruits or books as users, or omissions in the detection results.

[0115] In another possible implementation, a seat sensor (e.g., a pressure sensor) provided in a vehicle seat can be used to detect whether a user is in the vehicle. The pressure sensor can determine whether a user is in the vehicle based on whether the current pressure value detected is greater than or equal to a preset pressure threshold.

[0116] It should be understood that there may be children among the users in the vehicle. Since children are generally lighter in weight, if the preset pressure threshold is set too high, it may result in omissions in the detection results of children, and children may be forgotten in the vehicle, threatening the life safety of children. Therefore, in the present application, the preset pressure threshold can be set to a smaller value, for example, 2KGf or 3KGf, so as to ensure the accuracy of detecting whether there is a user in the vehicle; and the preset pressure threshold can be set by the user according to actual needs, or set when the vehicle leaves the factory, and the present application embodiment does not limit this.

[0117] Furthermore, when the seat sensor is used to detect whether there is a user in the vehicle, it is possible to detect whether the current pressure of the seat fluctuates within a preset time period (for example, 5 minutes); if it is detected that the current pressure of the seat fluctuates, for example, after the current pressure of the seat is detected to be 20KGf, it is detected that the current pressure of the seat becomes 26KGf after 5 minutes, and then becomes 11KGf after 2 minutes, indicating that the current object on the seat is active, it can be determined that there is a user in the vehicle.

[0118] It should be understood that the current pressure of the seat is detected continuously within a preset time period so as to monitor the current pressure of the seat in real time.

[0119] It should also be understood that in order to avoid detection errors caused by the user not moving for a short period of time, the preset time length can be set to a longer time to ensure the accuracy of detecting whether there is a user in the vehicle. For example, the preset time length can be set to 5 minutes, 10 minutes or 20 minutes, which is not limited to this in the embodiments of the present application.

[0120] Alternatively, when it is detected that the current pressure of the seat is less than or equal to the preset pressure threshold 2KGf and lasts for a long time, for example, 20 minutes, it can be determined that there is no user in the vehicle.

[0121] In order to ensure the accuracy of detecting whether there is a user in the vehicle, the above-mentioned image detection and pressure detection can also be combined to exclude the possibility of bags, fruits or books stored on the seats, thereby further increasing the accuracy of the detection results.

[0122] It should be understood that the presence of a user in the vehicle may also be detected by one or more of an infrared device, a radar device, and an ultra-wideband antenna, and the embodiments of the present application are not limited to this.

[0123] Furthermore, when it is determined that the vehicle is in a parking state and the engine is turned off, if a user is detected in the vehicle, the door locking may fail, so that the user may check whether there is a user in the vehicle after receiving a prompt message indicating the locking failure. Alternatively, if a user is detected in the vehicle after the door has been locked, the window may be controlled to open to a preset degree, for example, 20%, to ensure air circulation in the vehicle and thereby protect the life safety of the user in the vehicle.

[0124] It should be understood that since the users in the vehicle may be children, in order to prevent children from being injured due to climbing out of the window due to the window being too wide, the preset opening can be set to a smaller value, for example, less than or equal to 50%, or 40%. This embodiment of the present application is not limited to this.

[0125] Exemplarily, the above method also includes: obtaining the power status of the vehicle; if the power status is a power-off and power-on state, controlling the motor to reset.

[0126] The power state may include an off state, an on state, and a power-off and power-on state, and the power state may be used to indicate whether the vehicle is powered on.

[0127] For example, the power status monitoring module can obtain the current power status of the vehicle (for example, the power-off and power-on status), and transmit the obtained power status to the CAN network, so that when the door lock control module obtains the power-off and power-on status of the vehicle in the CAN network, it controls the motor in the door to reset.

[0128] In an embodiment of the present application, if the power status is a power-off and power-on status, the motor is controlled to be reset; since the motor in the door is controlled to be reset when the power status of the vehicle is obtained to be a power-off and power-on status, damage to the motor can be avoided when the vehicle is powered off and then powered on, thereby providing effective protection measures for the motor in the vehicle.

[0129] In order to further explain the protection measures provided to the motor when the vehicle's power supply state is power off and then power on, Figure 5 Provide specific instructions.

[0130] Figure 5It is a schematic diagram of the process of initializing the vehicle after powering off and then powering on provided in an embodiment of the present application.

[0131] For example, Figure 5 As shown, the method 500 includes the following implementation process:

[0132] S501, obtaining the power status of the vehicle.

[0133] Exemplarily, the vehicle body domain controller may obtain the current power state of the vehicle, for example, a power-off state or a power-off-and-power-on state.

[0134] S502, determine whether the power supply state is a power-off and power-on state. If so, execute S503; if not, execute S501.

[0135] For example, after the vehicle body domain controller obtains the current power state of the vehicle, it can determine whether the power state is in a power-off and power-on state. If it is determined that the power state of the vehicle is not in a power-off and power-on state, for example, in a power-off state, S501 can be continued to be executed to repeatedly obtain the power state of the vehicle.

[0136] Exemplarily, if it is determined that the power state of the vehicle is a power-off and power-on state, S503 may be executed.

[0137] S503, determine whether the self-priming reset switch is disconnected. If so, execute S504; if not, execute S509.

[0138] For example, when the vehicle's power supply state is in the power-off and power-on state, in order to protect the motor in the door that controls the door's self-priming, the motor can be controlled to reset when the power is off and then powered on, and the state of the motor can be judged, that is, whether the self-priming reset switch is disconnected.

[0139] Exemplarily, if the self-priming reset switch is disconnected, continue to execute S504.

[0140] S504, controlling the motor to perform electrolytic reset.

[0141] For example, if the self-priming reset switch is disconnected, it means that the motor cannot be reset, and the door lock control module can be used to control the motor in the door to perform electrolytic reset.

[0142] S505, determine whether there is current in the motor. If not, execute S506; if yes, execute S508.

[0143] For example, when the motor performs electrolytic reset, it is determined whether there is current in the motor. If there is no current in the motor, it indicates that the motor may be faulty, and S506 can be executed.

[0144] S506, determine whether it has timed out. If so, execute S507; if not, execute S508.

[0145] For example, when the motor may fail, it can be judged by whether the duration of the failure exceeds a set duration (e.g., 200ms) to avoid misjudgment due to poor signal contact or other reasons. If the duration of the motor failure is greater than 200ms, it indicates that the motor may fail, and S507 is continued.

[0146] S507, reporting electrolytic reset failure.

[0147] For example, if it is determined that the motor has failed, information about the electrolytic reset failure of the motor in the door can be sent to the user; the information about the electrolytic reset failure reported to the user can be a prompt message of the electrolytic reset failure displayed to the user on the dashboard of the vehicle, or a prompt message of the electrolytic reset failure can be sent to the user terminal through an information sending module in the vehicle.

[0148] S508, end.

[0149] For example, after the electrolysis reset fault is reported to the user, the initialization process of powering off and then powering on the vehicle may be terminated.

[0150] In a possible implementation, after executing S505, if there is current in the motor, it means that the motor is not faulty, and S508 can be executed.

[0151] In another possible implementation, after executing S506, if the duration of the motor fault is less than or equal to the set duration of 200ms, it indicates that it may be a misjudgment due to poor signal, and S508 may also be executed. The implementation method of S508 is described above and will not be repeated here.

[0152] For example, after S504, if it can be obtained through S505 that there is current in the motor, or it can be obtained in S506 that the duration when there is no current in the motor is less than or equal to the preset duration (that is, there is current in the motor within the preset duration), it means that the motor is not faulty and the initialization of motor electrolysis is completed.

[0153] Exemplarily, after executing S503 , if the self-priming reset switch is not disconnected (ie, connected), it means that the self-priming reset of the motor can be performed normally, and then S509 is continued to be executed.

[0154] S509, determine whether the ratchet switch and the door status switch are disconnected. If yes, execute S510; if not, execute S517.

[0155] Exemplarily, if the pawl switch and the door status switch are both off, S510 may be executed.

[0156] S510, controlling the motor to perform self-priming.

[0157] For example, if the pawl switch and the door status switch are both disconnected, the door lock control module can control the motor in the door to perform self-priming. And, it can be determined whether the motor performs self-priming successfully through S511 and S512.

[0158] S511, determine whether the self-priming reset switch is disconnected. If not, execute S512; if yes, execute S504.

[0159] For example, after the motor in the door is controlled to perform self-priming, the state of the self-priming reset switch is judged. If it can be determined through judgment that the number of times the self-priming reset switch is disconnected meets the preset number of times (for example, 3 times in a row), S504 to S508 can be executed, and the implementation methods of S504 to S508 refer to the above description, which will not be repeated here.

[0160] Exemplarily, after controlling the motor in the vehicle door to execute self-priming, if it can be determined through judgment that the number of times the self-priming reset switch is disconnected does not meet the preset number of times, that is, the self-priming reset switch is disconnected for 3 consecutive times, including any one or more times of not being disconnected, S512 can be executed.

[0161] S512, determine whether it has timed out. If so, execute S513; if not, execute S508.

[0162] Exemplarily, if the motor in the vehicle door performs self-priming, the number of times the self-priming reset switch is disconnected meets the preset number of times and does not exceed the set time (for example, 1.5s), S504 to S508 can be executed, and the implementation method of S504 to S508 can be found in the above description and will not be repeated here.

[0163] It should be understood that the time required for the self-priming reset switch to be disconnected can be set to 10ms or 12ms, which is not limited in the embodiment of the present application. In addition, the set time should be greater than or equal to the time required for the self-priming reset switch to be disconnected 3 times.

[0164] For example, if the time it takes for the motor in the door to perform self-priming reset is greater than the set time of 1.5s, or the number of times the self-priming reset switch is disconnected does not meet the preset number of times, it means that the motor has failed to perform self-priming, and the motor is controlled to perform self-priming reset by executing S513.

[0165] Exemplarily, after S510, if it can be obtained through S511 that the self-priming reset switch is disconnected, and it can be obtained in S512 that the self-priming reset has not timed out, it means that the motor has successfully executed self-priming, that is, when the vehicle is powered off and then powered on, the initialization of the motor self-priming is completed.

[0166] S513, controlling the motor to perform self-priming reset.

[0167] For example, when the motor in the vehicle door fails to self-prime, the door lock control module can be used to control the motor in the vehicle door to perform self-priming reset so that the motor returns to the initial state. And, S514 and S515 are used to determine whether the motor performs self-priming reset successfully.

[0168] S514, determine whether the self-priming reset switch is disconnected. If not, execute S515; if yes, execute S504.

[0169] Exemplarily, if the number of times the self-priming reset switch is disconnected meets the preset number of times, S504 to S508 can be executed, and the implementation method of S504 to S508 is described above and will not be repeated here.

[0170] Exemplarily, if the number of times the self-priming reset switch is disconnected does not meet the preset number of times, S515 can be executed.

[0171] S515, determine whether it has timed out. If so, execute S516; if not, execute S504.

[0172] Exemplarily, if the motor in the door performs self-priming reset, the number of times the self-priming reset switch is disconnected meets the preset number of times and does not exceed the set time, S504 to S508 can be executed, and the implementation method of S504 to S508 is described above and will not be repeated here.

[0173] For example, if the time for the motor in the door to perform self-priming and resetting is greater than the set time of 1.5s, or the number of disconnections of the self-priming and resetting switch does not meet the preset number of times, it can be determined that the motor has a fault and continue to execute S516.

[0174] S516, reporting self-priming reset fault.

[0175] For example, if it is determined that the motor has failed, information about the self-priming reset failure of the motor in the door can be sent to the user; the information reporting the self-priming reset failure to the user can be a prompt message of the self-priming reset failure displayed to the user on the vehicle's dashboard, or a prompt message of the self-priming reset failure sent to the user terminal through an information sending module in the vehicle.

[0176] In a possible implementation, after S516, S504 to S508 may be executed, and the implementation of S504 to S508 is described above and will not be repeated here.

[0177] Exemplarily, after S513, if it can be obtained through S514 that the self-priming reset switch is disconnected, and it can be obtained in S515 that the self-priming reset is not timed out, it means that the motor successfully performs the self-priming reset, the motor fault is eliminated, and the initialization of the motor self-priming is completed.

[0178] In a possible implementation, after S503, if the pawl switch and / or the door status switch is turned on, S517 may be executed.

[0179] S517, control the motor to perform self-priming reset.

[0180] For example, if the pawl switch and / or the door status switch are turned on, the door lock control module can control the motor in the door to perform a self-priming reset to restore the motor to an initial state.

[0181] S518, determine whether the self-priming reset switch is disconnected. If not, execute S519; if yes, execute S504.

[0182] Exemplarily, if the number of times the self-priming reset switch is disconnected meets the preset number, S504 to S508 may be executed, and the implementation method of S504 to S508 is described above and will not be repeated here.

[0183] Exemplarily, if the number of times the self-priming reset switch is disconnected does not meet the preset number of times, S519 can be executed.

[0184] S519, determine whether it has timed out. If so, execute S520; if not, execute S504.

[0185] Exemplarily, if the motor in the door performs self-priming reset, the number of times the self-priming reset switch is disconnected meets the preset number of times and does not exceed the set time, S504 to S508 can be executed, and the implementation method of S504 to S508 is described above and will not be repeated here.

[0186] Exemplarily, when the number of disconnections of the self-priming reset switch does not meet the preset number of times, if the time for the motor in the door to perform the self-priming reset is greater than the set time of 1.5s, it means that the motor may be faulty, and S520 continues to be executed.

[0187] S520, controlling the motor to perform self-priming.

[0188] Exemplarily, the door lock control module may be used to control the motor in the vehicle door to perform self-priming.

[0189] In a possible implementation, after S520, S514 to S516 and S504 to S508 may be executed; the implementation of S514 to S516 and S504 to S508 is described above and will not be repeated here.
