[0050] Figure 1 The flowchart of the vehicle rear panel control method provided by an embodiment of the present application is shown. Figure 1 As shown, the vehicle rear panel control method includes steps S101 to S103.

[0051] Step S101, obtaining the driving speed of the vehicle and the opening state of the rear panel of the vehicle.

[0052] Specifically, when the vehicle is in the starting state, the vehicle's driving speed can be obtained through the speed sensor on the vehicle, and the opening state of the rear panel of the vehicle can be detected by the sensor set on the rear panel of the vehicle, wherein the opening state of the vehicle includes an open state and a closed state.

[0053] Step S102, when the vehicle's running speed is greater than zero and less than a preset speed, and the rear panel of the vehicle trunk is in an open state, the rear panel of the vehicle trunk is controlled to be closed.

[0054] Specifically, when the vehicle's speed is greater than zero and less than a preset speed, it means that the vehicle is in a driving state, and the vehicle's driving speed is slow, and the rear panel of the trunk can be closed automatically and safely. During the vehicle's driving process, if the rear panel of the trunk is in an open state, it may cause a safety hazard to pedestrians or other vehicles around. Therefore, when the vehicle's driving speed is greater than zero and less than a preset speed, if it is detected that the rear panel of the trunk is in an open state, the rear panel of the trunk is controlled to close automatically to prevent the rear panel of the trunk from being opened when the vehicle is driving, causing a safety hazard.

[0055] Step S103, when the vehicle's travel speed is greater than or equal to a preset speed and the rear panel of the vehicle is in an open state, a prompt message is sent to the user.

[0056] Specifically, if the vehicle's speed is greater than or equal to the preset speed, it means that the vehicle is traveling at a relatively fast speed and cannot guarantee the safe automatic closing of the rear panel. If the rear panel is detected to be open, a prompt message is sent to the user. After receiving the prompt message, the user can stop the car in time and close the rear panel to prevent the rear panel from being opened when the vehicle is driving, which may cause safety hazards.

[0057] It should be noted that the designer can set the specific value of the preset speed according to actual needs, for example, the preset speed can be set to 3 km / h, 5 km / h, 7 km / h or other values. The prompt information may include text or image information displayed on the display screen of the vehicle, light or image information displayed on the instrument panel, and sound information emitted by the audio equipment on the vehicle.

[0058] If there are too many goods in the trunk, the trunk may not be completely closed when the rear panel is closed. The rear panel may get stuck in a certain position and the motor driving the rear panel may become blocked, causing the risk of motor burning out.

[0059] Based on the above problems, the present application provides a method for controlling the rear panel of a vehicle box, such as Figure 2 As shown, the vehicle rear panel control method includes steps S201 and S202 in addition to steps S101 to S103.

[0060] Step S201, obtaining the resistance experienced by the rear panel of the vehicle box during the closing process of the rear panel of the vehicle box.

[0061] Specifically, a pressure sensor may be provided on the rear panel of the vehicle box, and during the closing process of the rear panel of the vehicle box, the pressure sensor may be used to detect the resistance received by the rear panel of the vehicle box.

[0062] If there is no cargo in the trunk, the rear panel will not be squeezed by cargo during the closing process, and the resistance received by the rear panel is less than or equal to the preset resistance. If there is too much cargo in the trunk, for example, the cargo in the trunk exceeds the trunk range, the rear panel will be squeezed by cargo during the closing process, and the pressure sensor detects that the resistance received by the rear panel is greater than the preset resistance.

[0063] In order to ensure that the pressure sensor can effectively detect the resistance received by the rear panel of the vehicle trunk, multiple pressure sensors can be set, and the multiple pressure sensors are distributed on the entire rear panel of the vehicle trunk. At the same time, the pressure sensor can be set as a sheet pressure sensor to increase the detection area of ​​the pressure sensor, ensuring that the pressure sensor can effectively detect the resistance received by the rear panel of the vehicle trunk.

[0064] It should be noted that the designer can set the specific value of the preset resistance according to actual needs. For example, the preset resistance can be set to 5N, 8N, 10N or other values.

[0065] Step S202, when the resistance applied to the rear panel of the vehicle box is greater than the preset resistance, the rear panel of the vehicle box is controlled to stop closing, and a prompt message is sent to the user.

[0066] Specifically, when the resistance of the rear panel of the vehicle box is greater than the preset resistance, it means that there are a lot of goods in the vehicle box, and the goods in the vehicle box squeeze the rear panel of the vehicle box, so that the rear panel of the vehicle box cannot be completely closed. At this time, the rear panel of the vehicle box is controlled to stop closing and a prompt message is sent to the user. After receiving the prompt message, the user takes corresponding measures in time (for example, rearranging the goods in the vehicle box) so that the rear panel of the vehicle box can be completely closed, thereby preventing the hidden danger of motor damage caused by the motor driving the rear panel of the vehicle box from being blocked.

[0067] In one embodiment of the present application, after step S202, step S203 and step S204 are also included.

[0068] Step S203, controlling the rear panel of the vehicle to rotate in the opposite direction.

[0069] Specifically, when the resistance encountered by the rear panel of the vehicle trunk is greater than the preset resistance, in addition to controlling the rear panel of the vehicle trunk to stop closing and sending a prompt message to the user, the rear panel of the vehicle trunk is also controlled to rotate in the opposite direction, that is, the motor driving the rear panel of the vehicle trunk is controlled to rotate in the opposite direction to prevent the motor from being damaged by being blocked for a long time, thereby protecting the motor.

[0070] Step S204, when the resistance applied to the rear panel of the vehicle box is less than or equal to the preset resistance, the rear panel of the vehicle box is controlled to stop rotating.

[0071] Specifically, when the rear plate of the vehicle trunk is controlled to rotate in the opposite direction, the rear plate of the vehicle trunk will slowly move away from the cargo in the vehicle trunk. When the resistance applied to the rear plate of the vehicle trunk is less than or equal to the preset resistance, the cargo in the vehicle trunk will no longer squeeze the rear plate of the vehicle trunk, and the motor driving the rear plate of the vehicle trunk will not be blocked. At this time, the rear plate of the vehicle trunk is controlled to stop rotating, so that the rear plate of the vehicle trunk maintains its current position. There is no need to fully open the rear plate of the vehicle trunk, so as to prevent the rear plate of the vehicle trunk from being fully opened and posing a safety hazard to pedestrians or other vehicles around the vehicle.

[0072] When the rear panel of the vehicle is automatically closing, if there are pedestrians or other objects around the vehicle, the rear panel of the vehicle may pose a safety hazard to the pedestrians or other objects, and may also cause damage to the rear panel of the vehicle.

[0073] Based on the above problems, the present application provides a method for controlling the rear panel of a vehicle box, such as Figure 3 As shown, the vehicle rear panel control method includes steps S301 to S303.

[0074] Step S301, during the closing process of the rear panel of the vehicle box, obtaining the surrounding information of the rear panel of the vehicle box.

[0075] Specifically, during the closing process of the rear panel of the vehicle trunk, the surrounding information of the rear panel of the vehicle trunk may be acquired through an image acquisition device (eg, a camera) disposed on the vehicle.

[0076] Step S302, determining whether a rear panel closing condition is met based on the rear panel surrounding information.

[0077] Specifically, by analyzing the information around the rear panel of the vehicle trunk, it is determined whether the rear panel of the vehicle trunk can be closed automatically and safely, that is, whether the closing conditions of the rear panel of the vehicle trunk are met.

[0078] In one embodiment of the present application, step S302 includes steps S3021 to S3024.

[0079] Step S3021, extracting the position information of objects around the rear panel of the vehicle box from the information around the rear panel of the vehicle box.

[0080] Specifically, by analyzing the information around the rear panel of the vehicle, the position information of the objects around the rear panel of the vehicle is extracted from the information around the rear panel of the vehicle. The objects around the rear panel of the vehicle include pedestrians, surrounding vehicles, surrounding houses, surrounding trees and other objects.

[0081] Step S3022, determining whether objects around the vehicle compartment are on the movement trajectory when the rear panel of the vehicle compartment is closed.

[0082] Specifically, the designer can determine the motion trajectory of the rear panel when closing the vehicle according to the specific parameters of the vehicle, and store the determined motion trajectory. After determining the position information of the objects around the rear panel, it can be determined whether the objects around the rear panel are on the motion trajectory.

[0083] Step S3023, when it is determined that there is an object on the movement track of the rear panel of the vehicle trunk when it is closed, it is determined that the closing condition of the rear panel of the vehicle trunk is not met.

[0084] Specifically, when it is determined that there is an object on the movement trajectory of the rear panel when it is closing, the rear panel may collide with the object during the closing process, causing safety hazards to the object and the rear panel. At this time, it is determined that the closing conditions of the rear panel are not met.

[0085] Step S3024, when it is determined that there is no object on the movement track of the rear panel of the vehicle trunk when it is closed, it is determined that the closing condition of the rear panel of the vehicle trunk is met.

[0086] Specifically, when it is determined that there is no object on the movement track of the rear panel when closing, the rear panel will not collide with the object when closing, and the rear panel can be closed safely, then it is determined that the closing condition of the rear panel is met.

[0087] Step S303, when it is determined that the closing condition of the rear panel of the vehicle trunk is not met, the closing action of the rear panel of the vehicle trunk is controlled to stop, and a prompt message is sent to the user.

[0088] Specifically, when it is determined that the rear panel closing conditions are not met, the rear panel is controlled to stop closing to prevent the rear panel from colliding with objects. At the same time, a prompt message is sent to the user, who can take measures such as moving objects around the rear panel and alerting objects around the rear panel to ensure that there are no objects on the movement track of the rear panel when closing, thus ensuring that the rear panel can be closed safely.

[0089] In one embodiment of the present application, the vehicle rear panel control method further includes step S401 and step S402.

[0090] Step S401, obtaining the location of the vehicle key.

[0091] Specifically, the position of the vehicle key can be detected by a detection device on the vehicle.

[0092] Step S402, when the distance between the vehicle key and the vehicle is greater than a preset distance and the rear panel of the vehicle trunk is in an open state, a prompt message is sent to the user.

[0093] Specifically, when the distance between the vehicle key and the vehicle is greater than a preset distance, it means that the user is too far from the vehicle, the rear panel of the vehicle trunk is open, and the user may have forgotten to close the rear panel of the vehicle trunk. At this time, the vehicle sends a prompt message to the user, and after receiving the prompt message, the user knows that he has forgotten to close the rear panel of the vehicle trunk, and the user can close the rear panel of the vehicle trunk in time.

[0094] In one embodiment of the present application, the vehicle trunk rear panel control method further includes: when the vehicle trunk is in an open state and a closing signal is received, controlling the vehicle trunk rear panel to close.

[0095] Specifically, when the trunk is in the open state, no matter whether the vehicle's power mode is in the on state or the off state, and no matter whether the vehicle's central control lock is in the unlocked state or the locked state, the user can send a closing signal by operating the vehicle key, the trunk rear panel control switch in the cab, or the control switch on the trunk rear panel. After the vehicle receives the closing signal, it can control the trunk rear panel to close, thereby realizing the control of the closing of the trunk rear panel.

[0096] In one embodiment of the present application, the vehicle rear panel control method further includes step S501 and step S502.

[0097] Step S501, when the rear panel of the vehicle is in an open state, the driving speed of the vehicle is obtained.

[0098] Specifically, when a user places a large item in the vehicle box, the rear panel of the vehicle box cannot be closed. In this case, the user needs to keep the rear panel of the vehicle box open while driving the vehicle. In this case, the vehicle speed needs to be limited to ensure safe driving. At this time, the vehicle speed can be obtained through the speed sensor on the vehicle.

[0099] Step S502: When the vehicle's travel speed is greater than a threshold speed, an alarm message is sent to the user.

[0100] Specifically, when the vehicle's speed is greater than the threshold speed, it means that the vehicle is traveling too fast, and there is a risk that the goods in the vehicle box will fall off. At the same time, the goods in the vehicle box may cause safety hazards to objects around the vehicle. At this time, the vehicle sends an alarm message to the user to remind the user that the current vehicle is traveling too fast. After receiving the alarm message, the user can adjust the vehicle's speed in time to improve the safety of the vehicle.

[0101] It should be noted that the designer or user can set the specific value of the threshold speed according to actual needs. For example, the threshold speed can be set to 20Km / h, 30Km / h, 35Km / h or other values.

[0102] In one embodiment of the present application, the vehicle rear panel control method further includes steps S601 to S603.

[0103] Step S601, when the rear panel of the vehicle box is in an open state and the vehicle is in a driving state, image information of the goods in the vehicle box is obtained.

[0104] Specifically, when a user places large cargo in the trunk, the rear panel of the trunk may not be closed, and the user needs to drive the vehicle with the rear panel of the trunk open. During the driving process, the shaking and bumping of the vehicle may cause the cargo in the trunk to move, causing the cargo in the trunk to fall or extend out of the trunk. The cargo extending out of the trunk may collide with objects around the vehicle, causing safety hazards. Therefore, it is necessary to monitor the position of the cargo in the vehicle. Therefore, a camera can be set on the vehicle, which can collect image information of the trunk and the surrounding area of ​​the trunk to monitor the status of the cargo in the trunk.

[0105] Step S602: Determine whether there is a safety hazard in the cargo based on the image information of the cargo in the vehicle compartment.

[0106] Specifically, by analyzing the image information, the relative position information of the cargo and the carriage can be determined. The relative position information of the cargo and the carriage includes: whether the cargo is in the carriage, whether the cargo partially extends outside the carriage, the length of the cargo extending outside the carriage, etc.

[0107] Exemplarily, if the length of the cargo extending outside the vehicle box is greater than a preset length, it is determined that the cargo poses a safety hazard.

[0108] Specifically, if the length of the cargo extending outside the vehicle compartment is greater than a preset length, the portion extending outside the vehicle compartment may collide with objects around the vehicle while the vehicle is driving, causing a safety hazard.

[0109] By analyzing one image information, the relative position information of the cargo and the carriage can be determined. By analyzing multiple image information, the change in the relative position of the cargo and the carriage can be determined. That is, the movement trajectory of the cargo can be determined by analyzing the image information. By analyzing the movement trajectory of the cargo, it can be determined whether the cargo is likely to move out of the carriage, that is, whether the cargo has the risk of falling. When it is determined that the cargo has the risk of falling, it is determined that the cargo has a safety hazard.

[0110] When judging whether there are safety hazards in the cargo, in addition to determining based on the image information of the cargo in the vehicle compartment, analysis can also be conducted in conjunction with the vehicle's driving environment.

[0111] Exemplarily, when the rear panel of the vehicle trunk is in an open state and the vehicle is in driving, the driving environment information of the vehicle is obtained, and based on the driving environment information of the vehicle, it is determined whether there is a safety hazard in the cargo.

[0112] Specifically, when the rear panel of the vehicle is in an open state and the vehicle is in a driving state, the driving environment information of the vehicle can be obtained through the camera set on the vehicle, wherein the driving environment information may include the position of surrounding objects (other vehicles or objects). By analyzing the driving environment information, the distance between the vehicle and the surrounding objects can be determined. When the distance between the vehicle and the surrounding objects is less than the threshold distance, the vehicle may brake suddenly. Since the rear panel of the vehicle is in an open state at this time, sudden braking may cause safety hazards to the goods. Therefore, when the distance between the vehicle and the surrounding objects is less than the threshold distance, it is determined that there is a safety hazard to the goods.

[0113] Step S603: When it is determined that the goods have potential safety hazards, an alarm message is sent to the user.

[0114] Specifically, when it is determined that there is a safety hazard in the cargo, an alarm message is sent to the user. After receiving the alarm message, the user can adjust the driving status of the vehicle or sort out the cargo in the vehicle in a timely manner to eliminate the safety hazard and improve the safety of vehicle driving.

[0115] Exemplarily, the alarm information may include multiple types of hidden dangers, such as "hazard of cargo falling", "hazard of cargo causing danger to surrounding objects" and "hazard of excessive vehicle speed". The alarm information may be displayed in the form of text or pictures. The user can know the type of hidden danger in the alarm information by viewing the displayed text or pictures, and then take corresponding measures to eliminate the safety hazards. For example, when the user receives the alarm information of "hazard of cargo falling", the user can park the vehicle in a safe place in time, and then organize and fix the cargo in the car box to avoid the cargo falling. When the user receives the alarm information of "hazard of cargo causing danger to surrounding objects", the user can adjust the vehicle's driving route in time to avoid surrounding objects and prevent the cargo from colliding with surrounding objects. When the user receives the alarm information of "hazard of excessive vehicle speed", the user can adjust the vehicle speed in time to prevent damage to the cargo due to sudden braking.

[0116] The vehicle trunk rear panel control method provided in the embodiment of the present application detects the driving speed of the vehicle and the opening state of the vehicle trunk rear panel, and when the vehicle trunk rear panel is in the opening state, automatically closes the vehicle trunk rear panel or sends a prompt message to the user according to the driving speed of the vehicle. After receiving the prompt message, the user can close the vehicle trunk rear panel in time to prevent the vehicle trunk rear panel from opening when the vehicle is driving and causing safety hazards. At the same time, in the process of closing the vehicle trunk rear panel, the closing control of the vehicle trunk rear panel is realized by detecting the resistance of the vehicle trunk rear panel and the surrounding information of the vehicle trunk rear panel, so as to ensure the safety of the vehicle trunk rear panel when closing. When the user places too large goods in the vehicle trunk and the vehicle trunk rear panel cannot be closed, the image information of the goods in the vehicle trunk or the driving environment information of the vehicle is analyzed to determine whether there is a safety hazard in the goods in the vehicle trunk. When it is determined that there is a safety hazard, an alarm message is sent to the user, so that the user can timely sort the goods or adjust the driving state of the vehicle to ensure the safety of the vehicle trunk when the vehicle trunk rear panel cannot be closed. The rear panel control method provided in the embodiment of the present application integrates the control methods of the rear panel of the vehicle trunk in various situations into a complete rear panel control method of the vehicle trunk, and the complete rear panel control method of the vehicle trunk can be integrated into one controller, that is, one controller can complete the safety control of the rear panel of the vehicle trunk, and the number of controllers can be reduced, thereby reducing the production cost of the vehicle.
