[0059] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0060] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0061] Please refer to Figure 1, which shows a schematic diagram of a safety monitoring system for a rear panel of a vehicle provided by an exemplary embodiment. The system is applied in a pickup truck equipped with an automatic control switch for the rear panel of the vehicle. The system includes: a domain controller 10, a rear panel of the vehicle 20, a speed sensor 30 and a status indicator 40. The rear panel of the vehicle 20 is connected to the speed sensor 30, the speed sensor 30 is connected to the domain controller 10, and the domain controller 10 is connected to the status indicator 40.

[0062] The speed sensor 30 is used to monitor the output end rotation speed of the actuator of the rear panel 20 of the vehicle box, and send the output end rotation speed to the domain controller 10. The actuator of the rear panel 20 of the vehicle box is a mechanism for controlling the opening or closing of the rear panel 20 of the vehicle box.

[0063] The speed sensor 30 is arranged at the output end of the actuator of the rear panel 20 of the vehicle trunk, and is used to detect the output end rotation speed of the actuator. The actuator is a device for driving the rear panel 20 of the vehicle trunk to open or close in response to a switch instruction. For example, the actuator can be an electric rotary motor, etc. The switch instruction can be triggered in any form. For example, the vehicle control panel of the vehicle includes a control button of the rear panel 20 of the vehicle trunk, and the switch instruction can be generated based on the control button of the rear panel 20 of the vehicle trunk. The vehicle control panel can be a control panel in the cab or a control panel set in the car key, which is not specifically limited in the embodiment of the present application. Alternatively, the switch instruction is an instruction sent by the domain controller 10, and the domain controller 10 sends the switch instruction based on the driving condition of the vehicle. For example, the domain controller 10 determines that the driving condition of the vehicle is from the refined state to the driving state, and sends a closing instruction to the actuator.

[0064] The speed sensor 30 may be any type of sensor, for example, the speed sensor 30 may be a magnetoelectric vehicle speed sensor, a Hall type vehicle speed sensor, or a photoelectric vehicle speed sensor, etc. The speed sensor 30 is connected in communication with the domain controller 10, and after detecting the output speed of the actuator, the output speed is sent to the domain controller 10 through the communication connection.

[0065] The domain controller 10 is used to receive the output end rotational speed, determine the operating status of the rear panel 20 of the vehicle box based on the output end rotational speed, and when the operating status of the rear panel 20 indicates that the rear panel 20 of the vehicle box is operating abnormally, generate a first alarm instruction and send the first alarm instruction to the status indicator 40. The first alarm instruction is used to indicate that the rear panel 20 of the vehicle box is operating abnormally.

[0066] The domain controller 10 is a controller that controls different functional areas according to the different functions of the vehicle. The domain controller 10 involved in the embodiment of the present application is a body domain controller 10, which is used to control functional components of the body, such as brake lights, rear position lights, door locks, side panels of the vehicle, and rear panels 20 of the vehicle.

[0067] See also Figure 2 After receiving the output end speed, the domain controller 10 determines whether the vehicle box rear plate 20 is operating normally based on the output end speed. In some embodiments, the domain controller 10 includes a speed determination unit; the speed determination unit is used to obtain a preset speed range, and when the output end speed is within the preset speed range, it is determined that the vehicle box rear plate 20 is operating normally; when the output end speed is outside the preset speed range, it is determined that the vehicle box rear plate 20 is operating abnormally. The preset speed range can be set as needed, and in the embodiment of the present application, the preset speed range is not specifically limited.

[0068] In some embodiments, the system further includes a torque sensor, which is disposed at the output end of the actuator of the rear panel 20, and is used to detect the output end torque of the actuator, and send the output end torque to the domain controller 10. Accordingly, the domain controller 10 also receives the output end torque of the actuator sent by the torque sensor, and determines the operation status of the rear panel 20 based on the output end torque.

[0069] The domain controller 10 stores the change of the output torque of the actuator during the execution of the target action by the rear panel 20. When the domain controller 10 receives the output torque of the actuator sent by the torque sensor, it compares the output torque of the actuator with the change of the output torque of the actuator during the execution of the target action. When it is detected that the difference between the output torque of the current actuator and the output torque stored in the domain controller 10 is greater than the preset difference, it is determined that the rear panel 20 is operating abnormally.

[0070] The change of the output torque of the actuator during the target action of the rear panel 20 stored in the domain controller 10 may be in any form. For example, the change curve of the output torque of the actuator during the target action is stored in the domain controller 10. The change curve may be a change curve obtained by calibrating the output torque of the actuator during the target action of the rear panel 20 before the vehicle leaves the factory.

[0071] In the present implementation, by detecting the output end torque of the actuator and the stored change in the output end torque of the actuator during the execution of the target action, it is determined whether the rear plate 20 is running smoothly through the change in the output end torque. When abnormal operation of the rear plate is detected, the operating status of the rear plate can be reflected in time through the status indicator, thereby preventing damage to the rear plate and increasing the service life of the rear plate.

[0072] The status indicator 40 is used to receive the first alarm instruction, and output a first alarm signal based on the first alarm instruction.

[0073] The status indicator 40 can be a warning light, a horn or a display panel, etc. Accordingly, when the status indicator 40 is a warning light, the first alarm signal can be output by flashing the warning light. When the status indicator 40 is a horn, the first alarm signal can be output by honking the horn. When the status indicator 40 is a display panel, the first alarm signal can be output in the form of text or an alarm animation. In the embodiment of the present application, the type of the status indicator 40 and the output method of the first alarm signal are not specifically limited. The status indicator 40 can also be an on-board terminal of the vehicle. Accordingly, the first alarm signal is output through the display screen of the on-board terminal. For example, the display screen displays "The opening / closing of the rear panel of the vehicle is abnormal, please check the rear panel of the vehicle" and the like.

[0074] In some embodiments, the domain controller 10 also detects the cause of the abnormal operation of the rear panel of the vehicle trunk and outputs the cause through the vehicle's instrument. For example, the domain controller 10 determines that the cause of the abnormal operation of the rear panel of the vehicle trunk is that the opening or closing speed is too slow by determining the opening or closing speed of the rear panel of the vehicle trunk. Accordingly, the first alarm signal can be displayed on the display screen, "The rear panel of the vehicle trunk opens / closes slowly, and there may be other objects blocking it. Please check the rear panel of the vehicle trunk." For another example, the domain controller 10 determines that the cause of the abnormal operation of the rear panel of the vehicle trunk is that the output torque of the actuator is too small during the opening or closing process by determining the output torque of the actuator when the rear panel of the vehicle trunk is opened or closed. Accordingly, the first alarm signal can be displayed on the display screen, "The rear panel of the vehicle trunk is difficult to open / close. Please check whether the actuator is operating normally."

[0075] In this implementation, the cause of abnormal operation of the rear panel of the vehicle trunk is detected by the domain controller 10, and the cause of abnormal operation of the rear panel of the vehicle trunk 20 is output through the status indicator 40, so that the driver can promptly understand the cause of the abnormality and perform maintenance or repair in time to avoid more serious abnormalities.

[0076] Furthermore, by detecting the output end speed and output end torque of the actuator, it is determined whether the rear panel 20 is operating normally. In this way, the operating status of the rear panel 20 is determined from multiple aspects, thereby improving the accuracy of detecting the operating status of the rear panel 20.

[0077] The electronic device determines the reason why the target action is not completed by determining the locking state of the rear panel of the vehicle box. Accordingly, during the process of automatically opening or closing the rear panel of the vehicle box, if it is detected that the locking device cannot be opened or locked, the electronic device outputs a first alarm signal indicating that the locking device of the rear panel of the vehicle box is abnormal. The first alarm signal may be "the rear panel of the vehicle box cannot be locked or unlocked, please check the locking device" or the like.

[0078] It should be noted that when the vehicle outputs the first alarm signal, it can be output through one of the above-mentioned multiple instrument types, or it can be output through multiple types simultaneously. In the embodiments of the present application, there is no specific limitation on this.

[0079] In the embodiment of the present application, the domain controller 10 determines whether the rear panel 20 is operating normally based on the output end rotational speed, so that when it is detected that the rear panel 20 is operating abnormally, it can promptly reflect the operating status of the rear panel 20 through the status indicator 40, thereby preventing the rear panel 20 from being damaged and increasing the service life of the rear panel 20.

[0080] It should be noted that, when the rear panel 20 of the vehicle box is operating normally, the domain controller 10 can also send a normal state instruction to the status indicator 40 to control the status indicator 40 to output a normal indication signal. Accordingly, the domain controller 10 is also used to generate a normal state instruction when the operating status of the rear panel 20 of the vehicle box indicates that the rear panel 20 of the vehicle box is operating normally, and send the normal state instruction to the status indicator 40, and the normal state instruction is used to indicate that the rear panel 20 of the vehicle box is operating normally; the status indicator 40 is also used to receive the normal state instruction and output a normal indication signal based on the normal state instruction.

[0081] The principle of outputting the normal indication signal is the same as the principle of outputting the first alarm signal, which will not be described in detail here. In addition, the first alarm signal and the normal indication signal can be output in the same or different output modes. When the first alarm signal and the normal indication signal are output in the same mode, the output mode can be adjusted to distinguish the first alarm signal from the normal indication signal. For example, when the alarm light flashes, the first alarm signal and the normal indication signal can be distinguished by the flashing frequency of the alarm light.

[0082] In the embodiment of the present application, the domain controller 10 determines whether the rear panel 20 is operating normally based on the output end rotational speed. When it is detected that the rear panel 20 is operating normally, the operating status of the rear panel 20 can be reflected in time through the status indicator 40, so that the driver can understand the operating status of the rear panel 20 in time, thereby optimizing the driver's experience.

[0083] In some embodiments, see Figure 3 , the system can also determine whether the rear panel 20 of the vehicle box is operating abnormally by monitoring the time required for locking the rear panel 20 of the vehicle box. Accordingly, the system also includes: a locking unit; the domain controller 10 is used to send a locking instruction to the actuator of the rear panel 20 of the vehicle box; the actuator of the rear panel 20 of the vehicle box is used to receive the locking instruction, and control the rear panel 20 of the vehicle box to perform a closing action based on the locking instruction until the rear panel 20 of the vehicle box is locked; the locking unit is used to send a locking signal to the domain controller 10 in response to detecting that the rear panel 20 of the vehicle box is locked; the domain controller 10 is also used to start timing after the locking instruction is sent, and when the locking signal sent by the locking unit is not received within a preset time, a second alarm instruction is generated, and the second alarm instruction is used to indicate that the rear panel 20 of the vehicle box is locked abnormally; the status indicator 40 is used to receive the second alarm instruction, and output a second alarm signal based on the second alarm instruction.

[0084] In some embodiments, the locking unit includes a position sensor and a locking device. The locking unit locks the rear panel 20 in an open position or a closed position. Accordingly, the locking unit can be set in the open position and the closed position of the rear panel 20. The locking unit set in the open position is used to monitor whether the rear panel 20 is opened normally, and the locking unit set in the closed position is used to monitor whether the rear panel 20 is closed normally.

[0085] For example, after the actuator of the rear panel 20 receives the closing command, the rear panel 20 is driven by the actuator to reach the fully locked position. If the rear panel 20 does not reach the fully locked position within 2 seconds, that is, the domain controller 10 does not receive the locking signal, it is determined that the rear panel 20 is closed abnormally, and the status indicator 40 displays the rear panel abnormality, reminding the owner to check and repair. The principle of outputting the second alarm signal is the same as the principle of outputting the first alarm signal, which will not be repeated here.

[0086] In the present implementation, the domain controller 10 determines whether the rear panel 20 is operating normally by monitoring whether it is locked within a preset time period, thereby preventing the rear panel 20 from being stuck during operation and being unable to open or close normally, causing the rear panel 20 to operate unstable, thereby reducing damage to the rear panel 20 and further increasing the service life of the rear panel 20.

[0087] One point that needs to be explained is that the embodiments of the present application are implemented when the power supply of the entire vehicle is in a powered-on state, wherein the powered-on state of the power supply includes any gear position of the power supply, for example, START vehicle start gear, LOCK vehicle lock gear, ACC accessory power-on gear, and ON vehicle power-on gear.

[0088] In some embodiments, the system further includes: an automatic control module for the rear panel 20. The operation modes of the rear panel 20 include a manual operation mode and an automatic operation mode. In the manual operation mode, the rear panel 20 is opened or closed based on external force control. In the automatic operation mode, the rear panel 20 can be automatically opened or closed under the control of the automatic control module for the rear panel 20.

[0089] Among them, the automatic control module of the rear panel 20 of the vehicle trunk is used to respond to the switch instruction of the rear panel 20 of the vehicle trunk, and control the rear panel 20 of the vehicle trunk to automatically complete the opening action or the closing action. The switch instruction of the rear panel 20 of the vehicle trunk can be triggered in any form. In some embodiments, in response to the control instruction, the automatic control module of the rear panel 20 of the vehicle trunk controls the opening or closing of the rear panel 20 of the vehicle trunk based on the control instruction. In some embodiments, the control instruction can be triggered in any form, for example, the vehicle control panel of the vehicle includes a control button of the rear panel 20 of the vehicle trunk, and the control instruction can be generated based on the control button of the rear panel 20 of the vehicle trunk. The vehicle control panel can be a control panel in the cab or a control panel set in the car key, which is not specifically limited in the embodiments of the present application.

[0090] In some embodiments, the system further includes a switch monitoring module for the rear panel 20 of the vehicle box, which is used to monitor whether the rear panel 20 of the vehicle box has completed a complete opening action or a closing action. In some embodiments, the switch monitoring module for the rear panel 20 of the vehicle box is an angle sensor, which is used to detect the opening angle of the rear panel 20 of the vehicle box and send the opening angle to the domain controller 10. In some embodiments, the switch detection module for the rear panel 20 of the vehicle box is a locking sensor. Accordingly, when the rear panel 20 of the vehicle box completes the opening action or the closing action, it is locked in the open position or the closed position. The locking sensor is used to detect that when the rear panel 20 of the vehicle box is locked in the open position or the closed position, it sends a locking signal to the domain controller 10.

[0091] The domain controller 10 is also used to determine whether the rear panel 20 of the vehicle box has completed a complete opening action or a closing action based on the information sent by the switch monitoring module of the rear panel 20 of the vehicle box. Accordingly, in the case where the switch monitoring module of the rear panel 20 of the vehicle box is an angle sensor, the domain controller 10 is used to determine whether the rear panel 20 of the vehicle box has completed a complete opening action or a closing action based on the opening angle sent by the angle sensor. If the opening angle reaches the maximum angle, it is determined that the rear panel 20 of the vehicle box has completed a complete opening action, and if the opening angle reaches the minimum angle, it is determined that the rear panel 20 of the vehicle box has completed a complete closing action. In the case where the switch monitoring module of the rear panel 20 of the vehicle box is a locking sensor, the domain controller 10 starts in time when the automatic control module of the rear panel 20 of the vehicle box starts to open or close the rear panel 20 of the vehicle box. If the locking signal sent by the locking sensor is not received within the preset time, it is determined that the rear panel 20 of the vehicle box has not completed a complete opening action or a closing action.

[0092] In an embodiment of the present application, the domain controller determines whether the rear plate of the vehicle box is operating normally based on the output end rotational speed, so that when abnormal operation of the rear plate of the vehicle box is detected, the operating status of the rear plate of the vehicle box can be reflected in time through the status indicator, thereby preventing damage to the rear plate of the vehicle box and increasing the service life of the rear plate of the vehicle box.

[0093] See also Figure 4 , which shows a flow chart of a vehicle rear panel safety detection method provided by the present application. As an example but not a limitation, the method is applied to an electronic device, which may be a domain controller of a vehicle, etc. The electronic device is equipped with the above-mentioned vehicle rear panel safety detection system.

[0094] S401, the electronic device obtains the output end rotation speed of the actuator of the rear panel of the vehicle box, and the actuator of the rear panel of the vehicle box is a mechanism for controlling the opening or closing of the rear panel of the vehicle box.

[0095] The electronic device determines the output speed of the actuator through a speed sensor. The speed sensor is arranged at the output end of the actuator of the rear panel of the vehicle trunk, and is used to detect the output speed of the actuator. The actuator is a device for driving the rear panel of the vehicle trunk to open or close in response to a switch instruction. For example, the actuator may be an electric rotary motor, etc. The switch instruction may be triggered in any form. For example, the vehicle control panel of the vehicle includes a rear panel control button of the vehicle trunk, and the switch instruction may be generated based on the rear panel control button of the vehicle trunk. The vehicle control panel may be a control panel in the cab or a control panel provided in the car key, and in the embodiment of the present application, no specific limitation is made to this. Alternatively, the switch instruction is an instruction sent by a domain controller, and the domain controller sends a switch instruction based on the driving condition of the vehicle.
