Description

Technical Field

[0001] This invention relates to the field of vehicle control technology, and in particular to a method, device, equipment, and storage medium for controlling a concealed external handle. Background Technology

[0002] Hidden door handles, as a new type of car door handle, can retract when not in use, blending in with other parts of the door to achieve a concealed effect. This does not disrupt the overall design of the vehicle, resulting in a simple and aesthetically pleasing appearance. At the same time, they reduce air resistance during dynamic driving and are gradually becoming a feature of new energy vehicles, with a trend of further expansion.

[0003] In everyday use, the electric pop-out function of both rotary and flat-out electric retractable outer handles can meet the need for convenient operation. However, manually opening the retractable outer handle from outside the vehicle is extremely inconvenient and difficult. This makes it difficult for rescuers to operate the retractable outer handle from outside the vehicle in the event of a sudden emergency, thus hindering timely rescue and potentially causing serious injury to the user.

[0004] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is prior art. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides a method for controlling a concealed external handle, the method comprising the following steps:

[0007] The vehicle's operating status is continuously monitored while it is powered on.

[0008] If the operating state meets the preset danger judgment conditions, then a door lock control command and a handle control command are generated;

[0009] The vehicle doors are unlocked according to the door lock control command, and the hidden outer door handle of the vehicle is popped out according to the handle control command.

[0010] Optionally, the step of continuously monitoring the operating status of the vehicle while it is powered on includes:

[0013] Optionally, the step of continuously monitoring the operating status of the vehicle while it is powered on includes:

[0014] While the vehicle is powered on and running, the vehicle's acceleration is continuously monitored;

[0015] When the vehicle acceleration is negative and the absolute value of the vehicle acceleration is greater than a preset braking threshold, the vehicle's speed is monitored.

[0016] If the driving speed decreases to less than or equal to a preset threshold within a preset time period, the vehicle's operating status is determined to meet the preset danger determination conditions.

[0017] Optionally, the step of continuously monitoring the operating status of the vehicle while it is powered on includes:

[0018] When the vehicle is powered on and running, the collected values ​​from the disaster monitoring module in the vehicle are obtained;

[0019] If the collected value is greater than the preset collection threshold, the vehicle's operating status is determined to meet the preset hazard determination conditions.

[0020] Optionally, after the steps of controlling the vehicle to unlock the doors according to the door lock control command and controlling the vehicle to pop out the concealed outer door handle according to the handle control command, the method further includes:

[0021] Detect whether the vehicle door is opened;

[0022] If the vehicle door is not opened and the vehicle speed increases to exceed a preset driving threshold, a door lock closing command and a handle retraction command are generated.

[0023] The vehicle doors are locked according to the door lock closing command, and the hidden outer handle of the vehicle is retracted according to the handle retraction command.

[0024] Optionally, the steps of controlling the vehicle to unlock its doors according to the door lock control command and controlling the hidden outer door handle of the vehicle to pop out according to the door handle control command include:

[0025] Obtain the moment of the emergency assessment, as well as the door unlocking time and handle extension time of the corresponding vehicle.

[0026] The door lock control time and handle control time are constructed based on the door unlocking time, the handle popping time, and the emergency determination time.

[0027] Based on the door lock control timing, the vehicle doors are unlocked according to the door lock control command, and based on the handle control timing, the hidden outer handle of the vehicle is popped out according to the handle control command.

[0028] Optionally, the step of constructing the door lock control time and handle control time based on the door unlocking time, the handle popping out time, and the moment of danger determination includes:

[0029] The door unlocking time and the handle pop-out time are set according to the door unlocking time and the handle pop-out time, and the sum of the door unlocking time and the door lock delay time is less than or equal to the sum of the handle pop-out time and the handle delay time.

[0030] The door lock control time is determined based on the time of the emergency assessment and the door lock delay duration.

[0031] The timing for controlling the handle is determined based on the time of the hazard assessment and the delay time of the handle.

[0032] Furthermore, to achieve the above objectives, the present invention also proposes a concealed external handle control device, which includes the following modules:

[0033] The monitoring module is used to continuously monitor the operating status of the vehicle when it is powered on.

[0037] Furthermore, to achieve the above objectives, the present invention also proposes a computer-readable storage medium storing a hidden external handle control program, wherein the hidden external handle control program, when executed, implements the steps of the hidden external handle control method as described above.

[0038] This invention continuously monitors the vehicle's operating status while it is powered on. If the operating status meets preset hazard assessment conditions, it generates door lock control commands and handle control commands. The door lock control commands unlock the vehicle's doors, and the handle control commands pop out the hidden external handles. Because the vehicle unlocks its doors and pops out the hidden external handles when the preset hazard assessment conditions are detected and an accident occurs, rescue personnel will not face difficulties opening the doors, ensuring timely rescue for occupants and reducing the risk of secondary injury.

[0047] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0048] Reference Figure 1 , Figure 1 This is a schematic diagram of the hidden external handle control device structure in the hardware operating environment involved in the embodiment of the present invention.

[0049] like Figure 1As shown, the electronic device may include: a processor 1001, such as a central processing unit (CPU), a communication bus 1002, a user interface 1003, a network interface 1004, and a memory 1005. The communication bus 1002 is used to enable communication between these components. The user interface 1003 may include a display screen or an input unit such as a keyboard; optionally, the user interface 1003 may also include a standard wired interface or a wireless interface. The network interface 1004 may optionally include a standard wired interface or a wireless interface (such as a Wireless-Fidelity (Wi-Fi) interface). The memory 1005 may be high-speed random access memory (RAM) or stable non-volatile memory (NVM), such as a disk drive. The memory 1005 may also optionally be a storage device independent of the aforementioned processor 1001.

[0050] Those skilled in the art will understand that Figure 1 The structure shown does not constitute a limitation on the electronic device and may include more or fewer components than shown, or combine certain components, or have different component arrangements.

[0051] like Figure 1 As shown, the memory 1005, which serves as a storage medium, may include an operating system, a network communication module, a user interface module, and a hidden external handle control program.

[0052] exist Figure 1 In the electronic device shown, the network interface 1004 is mainly used for data communication with the network server; the user interface 1003 is mainly used for data interaction with the user; the processor 1001 and the memory 1005 in the electronic device of the present invention can be set in the hidden external handle control device. The electronic device calls the hidden external handle control program stored in the memory 1005 through the processor 1001 and executes the hidden external handle control method provided in the embodiment of the present invention.

[0053] This invention provides a method for controlling a concealed external handle, referring to... Figure 2 , Figure 2 This is a flowchart illustrating the first embodiment of a hidden external handle control method according to the present invention.

[0054] In this embodiment, the method for controlling the hidden external handle includes the following steps:

[0055] Step S10: While the vehicle is powered on, continuously monitor the vehicle's operating status.

[0056] It should be noted that the main body of this embodiment can be a hidden external handle control device (hereinafter referred to as handle control device) or the vehicle itself. The handle control device can be a controller in the vehicle, such as an ECU controller, or other devices that can achieve the same or similar functions. This embodiment does not limit this. In this embodiment and the following embodiments, the hidden external handle control method of the present invention is described using the handle control device as an example.

[0057] It should be noted that when the vehicle is powered on and running normally, that is, when the vehicle is driving normally, due to the uncertainties in the driving process, accidents may occur at any time. Therefore, it is necessary to continuously monitor the vehicle's operating status, which can include the vehicle's speed and the data collected by various sensors in the vehicle.

[0058] Specifically, continuous monitoring of the vehicle's operating status can be done periodically by using a preset time period. The preset time period can be set in advance by the administrator of the handle control device. In order to ensure that accidents can be detected in time, the value of the preset time period can be set to a small value, for example, setting the preset time period to 1 second.

[0059] Step S20: If the operating state meets the preset danger judgment conditions, then generate door lock control command and handle control command.

[0060] Understandably, if the operating status meets the preset danger judgment conditions, it means that the vehicle may have encountered an accident. In order to ensure that rescuers can carry out rescue in a timely manner after the accident, door lock control commands and handle control commands can be generated at this time.

[0061] In actual use, when the operating status meets the preset danger judgment conditions, in order to make the user clear about the judgment reason and to facilitate the management center to discover the danger, the reason for the judgment that the operating status meets the preset danger judgment conditions can also be sent to the vehicle's mobile phone interconnection intelligent system (DA), vehicle management APP or vehicle management center to send a prompt, such as: airbags deploy, the vehicle experiences an emergency braking event or the vehicle catches fire, and the door locks and outer handles will unlock, etc.

[0062] In practical applications, in the event of an accident, the vehicle's airbags will deploy to protect the driver. Therefore, when determining whether the vehicle's operating status meets the preset hazard assessment conditions, this can be determined based on whether the airbags have deployed. In this case, step S10 of this embodiment may include:

[0063] When the vehicle is powered on, the trigger status of the airbag sensors in the vehicle is acquired;

[0064] If the airbag sensor is triggered and the airbag is activated, the vehicle's operating status is determined to meet the preset hazard determination conditions.

[0065] It should be noted that the airbag sensor can be a sensor installed in the vehicle to detect whether the airbag has deployed.

[0066] It is understandable that if the airbag sensor triggers the airbag, it means that the vehicle has been involved in a severe collision, and the vehicle can be considered to have been involved in an accident. Therefore, it can be determined that the vehicle's operating status meets the preset danger judgment conditions.

[0067] In actual use, the deployment of airbags generally indicates that the vehicle has been involved in a severe collision. The time required for airbag deployment is very short (only tens of milliseconds). When the airbag sensor changes from the triggered state to the airbag being triggered, it can directly send a signal to the handle control device without waiting for the handle control device to periodically collect the airbag sensor readings. This allows the handle control device to accurately obtain the moment of the collision and facilitate response.

[0068] Furthermore, since in some cases even if a vehicle collision occurs, the airbags may not deploy, such as when the point of impact happens to avoid the airbag's sensing point, in order to still ensure the user's safety as much as possible in this situation, the vehicle speed can also be used to determine whether a dangerous situation has occurred. In this case, step S10 of this embodiment may also include:

[0069] While the vehicle is powered on and running, the vehicle's acceleration is continuously monitored;

[0070] When the vehicle acceleration is negative and the absolute value of the vehicle acceleration is greater than a preset braking threshold, the vehicle's speed is monitored.

[0071] If the driving speed decreases to less than or equal to a preset threshold within a preset time period, the vehicle's operating status is determined to meet the preset danger determination conditions.

[0072] It should be noted that vehicle acceleration can be the change in vehicle speed over a certain period of time (such as within 1 second). Monitoring vehicle acceleration can be achieved by periodically acquiring the vehicle's speed and comparing it with previously collected speed data to determine the vehicle's acceleration.

[0073] Understandably, if the vehicle's acceleration is negative, it means that the vehicle is braking. If the absolute value of the vehicle's acceleration is greater than the preset braking threshold, it means that the vehicle is performing emergency braking, and a collision may occur. To determine whether a collision has occurred, the vehicle's speed can be monitored. If the vehicle's speed decreases to less than or equal to the preset judgment threshold within a preset time, it means that the vehicle has performed emergency braking and stopped. This indicates that a collision has most likely occurred, and the vehicle's operating state can be determined to meet the preset danger judgment conditions.

[0074] In practice, the preset braking threshold, preset judgment threshold, and preset duration can all be preset by the administrator of the handle control device. Since the change in vehicle speed is very large when emergency braking occurs before a collision, the preset braking threshold can be set relatively high. After a collision, the vehicle will come to a stop in a short time, meaning that the vehicle's speed will decrease to less than or equal to the preset judgment threshold (which can be set to 0 km / h or a very small value, such as 0.3 km / h). Therefore, the preset duration can be set relatively short, such as 3 seconds.

[0075] Furthermore, since the airbags will not actually deploy when other dangerous situations occur (such as when the vehicle catches fire), and the vehicle's speed will not change significantly, in order to protect the user's safety, step S10 in this embodiment may also include:

[0076] When the vehicle is powered on and running, the collected values ​​from the disaster monitoring module in the vehicle are obtained;

[0077] If the collected value is greater than the preset collection threshold, the vehicle's operating status is determined to meet the preset hazard determination conditions.

[0078] It should be noted that the disaster monitoring module can be a detection module installed in a vehicle to detect events such as vehicle fires. The disaster monitoring module can consist of at least one of a temperature rise sensor, a smoke concentration sensor, or a flame sensor. The preset acquisition threshold can be pre-set by the handle control device according to the specific configuration of the disaster monitoring module; different preset acquisition thresholds can be set for different sensors.

[0079] It is understandable that if the value collected by the disaster monitoring module is greater than the preset collection threshold, it means that a fire may have occurred in the vehicle. Therefore, it can be determined that the vehicle's operating status meets the preset danger judgment conditions.

[0080] In practical use, the disaster monitoring module may consist of multiple different sensors. In this case, as long as the value collected by any one of the sensors is greater than the preset collection threshold corresponding to that sensor, it can be determined that the vehicle's operating status meets the preset danger judgment conditions.

[0081] Step S30: Control the vehicle to unlock the doors according to the door lock control command, and control the hidden outer door handle of the vehicle to pop out according to the handle control command.

[0082] It should be noted that controlling the vehicle door to unlock according to the door lock control command can be done by sending the door lock control command to the vehicle's door lock actuator, causing the door lock actuator to start actuating, thereby controlling the internal mechanism of the vehicle door lock to change from the locked position to the unlocked position;

[0083] Similarly, controlling the pop-out of the vehicle's hidden outer handle according to the handle control command can be achieved by sending the handle control command to the handle actuator corresponding to the hidden outer handle, causing the handle actuator to actuate and control the internal structure of the hidden outer handle to change from a fully closed position to a pre-open position, that is, controlling the hidden outer handle to pop out.

[0084] In a specific implementation, when controlling the vehicle to unlock the doors and pop out the hidden outer handles, the door locks and outer handles of all the doors of the vehicle can be controlled, or only the door locks and outer handles of some doors can be controlled (such as symmetrical, only the door locks and outer handles of the driver's cabin and the door on the opposite side of the driver's cabin can be controlled). This embodiment does not limit this.

[0085] This embodiment continuously monitors the vehicle's operating status while it is powered on. If the operating status meets preset hazard judgment conditions, it generates door lock control commands and handle control commands. The door lock control commands unlock the vehicle's doors, and the handle control commands pop out the hidden external handles. Because the vehicle's doors are unlocked and the hidden external handles pop out when the vehicle's operating status meets preset hazard judgment conditions or when an accident occurs, rescue personnel will not face difficulties opening the doors, ensuring timely rescue for occupants and reducing the risk of secondary injury.

[0086] refer to Figure 3 , Figure 3 This is a flowchart illustrating a second embodiment of a hidden external handle control method according to the present invention.

[0087] Based on the first embodiment described above, step S30 of the hidden external handle control method in this embodiment includes:

[0088] Step S301: Obtain the time of the emergency assessment, as well as the door unlocking time and handle pop-out time of the corresponding vehicle.

[0089] It should be noted that the moment of hazard determination can be the moment a hazard is determined to have occurred, such as the moment the airbag deploys, the moment the value collected by the vehicle's hazard monitoring module exceeds a preset threshold, or the moment the vehicle's speed drops to 0 after emergency braking. The door unlocking time can be the time required for the door lock actuator to actuate, controlling the internal mechanism of the door lock from the locked position to the unlocked position. The handle ejection time can be the time required for the handle actuator corresponding to the hidden outer handle to actuate, controlling the internal structure of the hidden outer handle from the fully closed position to the pre-open position.

[0090] The door unlocking time and handle extension time can be pre-calibrated by the personnel in charge of the handle control equipment according to the vehicle's hardware model.

[0091] Step S302: Construct the door lock control time and handle control time based on the door unlocking time, the handle popping out time, and the emergency determination time.

[0092] It should be noted that the door lock control moment can be the start moment of controlling the door lock actuator, and the handle control moment can be the start moment of controlling the handle actuator.

[0093] Understandably, in order to prevent the risk of passengers being thrown out of the vehicle during an accident, the door locks should not be unlocked too early and the outer handles should not be extended too early when a dangerous situation occurs. Therefore, it is necessary to construct the door lock control timing based on the time of danger assessment and the duration of door unlocking, and the handle control timing based on the time of danger assessment and the duration of handle extension.

[0094] Furthermore, to ensure that the hidden outer handle can be pulled directly to open the car door after it pops out, step S302 in this embodiment may include:

[0095] The door lock delay time and the handle delay time are set according to the door unlocking time and the handle popping time;

[0096] The door lock control time is determined based on the time of the emergency assessment and the door lock delay duration.

[0097] The timing for controlling the handle is determined based on the time of the hazard assessment and the delay time of the handle.

[0098] It should be noted that setting the door lock delay time and handle delay time based on the door unlocking time and handle pop-out time can be done by determining the door lock delay value range based on the preset emergency duration and door unlocking time, determining the handle delay value range based on the preset emergency duration and handle delay time, and then selecting the door lock delay time and the handle delay time from the door lock delay value range.

[0099] The preset duration of the emergency can be pre-set by the administrator of the handle control device, for example, setting it to 4 seconds. When selecting the door lock delay duration from the range of door lock delay values ​​and the handle delay duration from the range of handle delay values, both the door lock delay duration and the handle delay duration should be kept as small as possible, and the sum of the door unlocking time and the door lock delay duration should be less than or equal to the sum of the handle ejection time and the handle delay duration.

[0100] In practical use, determining the range of door lock delay values ​​based on the preset duration of the emergency and the door unlocking time can be achieved by subtracting the door unlocking time from the preset duration of the emergency to obtain the minimum door lock delay. The range of handle delay values ​​can then be constructed based on this minimum door lock delay. For example, assuming the preset duration of the emergency is 4 seconds and the door unlocking time is 2 seconds, the minimum door lock delay is 2 seconds, and the handle delay range is (2, +∞). The method for obtaining the handle delay range is the same as that for obtaining the door lock delay range, and will not be repeated here.

[0101] In practical implementation, determining the door lock control time based on the hazard assessment time and the door lock delay time can be achieved by adding the hazard assessment time and the door lock delay time together. Similarly, determining the handle control time based on the hazard assessment time and the handle delay time can be achieved by adding the hazard assessment time and the handle delay time together.

[0102] Step S303: Based on the door lock control moment, control the vehicle to unlock the doors according to the door lock control command, and based on the handle control moment, control the hidden outer handle of the vehicle to pop out according to the handle control command.

[0103] It should be noted that controlling the vehicle doors to unlock based on the door lock control command at the door lock control moment can be achieved by sending the door lock control command to the vehicle's door lock actuator at the door lock control moment, so that the door lock actuator starts to operate and unlock the door at the door lock control moment. Alternatively, if the vehicle's door lock actuator supports a timed execution function, the door lock control moment and the door lock control command can be sent to the door lock actuator together, causing the door lock actuator to start operating according to the door lock control command at the door lock control moment.

[0104] Based on the handle control timing, controlling the pop-up of the vehicle's hidden outer handle according to the handle control command can be achieved by sending the handle control command to the corresponding handle actuator at the handle control timing, so that the handle actuator starts to operate at the handle control timing. Similarly, if the handle actuator supports timed execution function, the handle control timing and handle control command can also be sent to the handle actuator together.

[0105] To facilitate understanding, we will now combine... Figure 4This explanation is provided, but it does not limit the scope of this solution. Figure 4 This is a schematic diagram of the unlocking timing in this embodiment. Figure 4 In this system, the triggering time of the airbag controller (airbag deployment time) is used as the time for determining the danger. t1 is the door lock delay time, t2 is the handle delay time, t3 is the door unlocking time, t4 is the handle popping time, and t5 is the pre-opening time of the outer handle, i.e., the time when the hidden outer handle is fully popped out. t5 = airbag deployment time + t2 + t4. In order to ensure that the hidden outer handle can be pulled directly to open the door after it pops out, the door lock unlocking time (i.e., the time when the door lock is fully unlocked) needs to be earlier than the pre-opening time of the outer handle t5. In order to avoid the occupants being thrown out of the vehicle during an accident, t5 should be less than the airbag deployment time + the preset danger duration.

[0106] This embodiment acquires the moment of hazard determination, as well as the door unlocking duration and handle pop-out duration corresponding to the vehicle. Based on these parameters, it constructs the door lock control moment and handle control moment. Then, based on the door lock control moment, it controls the vehicle to unlock its doors according to the door lock control command, and based on the handle control moment, it controls the pop-out of the vehicle's hidden external handle according to the handle control command. Because the door lock control moment and handle control moment are constructed based on these parameters, and then the vehicle is controlled to unlock its doors according to the door lock control command, and the hidden external handle is popped out according to the handle control moment, the collision is ensured to be completed when the vehicle's door locks are unlocked and the external handle is popped out, thus preventing occupants from being ejected during an accident and improving safety.

[0107] refer to Figure 5 , Figure 5 This is a flowchart illustrating a third embodiment of a hidden external handle control method of the present invention.

[0108] Based on the first embodiment described above, after step S30 of the hidden external handle control method in this embodiment, it further includes:

[0109] Step S40: Detect whether the vehicle door is opened.

[0110] It should be noted that after the user determines that the danger has not affected their own safety, or after the user has successfully avoided the danger, the user may try to drive the vehicle away again. In general, during this process, since the danger is relatively minor, the user will not open the car door. Therefore, after step S30 is completed, it is also possible to detect whether the vehicle door has been opened.

[0111] It is understandable that if the airbags have already deployed, it means that the vehicle has suffered a relatively serious collision, and it is almost impossible to resume normal driving at this time. Therefore, it is not necessary to perform step S40 and subsequent steps in this embodiment.

[0112] Step S50: If the vehicle door is not opened and the vehicle speed increases to exceed a preset driving threshold, a door lock closing command and a handle retraction command are generated.

[0113] Understandably, if the vehicle door is not opened and the vehicle speed increases to exceed the preset driving threshold, it means that the user has determined that the danger has been eliminated (such as avoiding a collision through emergency avoidance, or the cause of the fire inside the vehicle has been dealt with), and the user has continued to try to drive normally. At this time, in order to ensure the user's safety, it is necessary to lock the door and retract the outwardly extended handle. Therefore, a door lock closing command and a handle retraction command can be generated.

[0114] Step S60: Control the vehicle to lock the doors according to the door lock closing command, and control the hidden outer handle of the vehicle to retract according to the handle retraction command.

[0115] It should be noted that controlling the vehicle door to lock according to the door lock closing command can be achieved by sending the door lock closing command to the vehicle's door lock actuator, causing the door lock actuator to start actuating, thereby controlling the internal mechanism of the vehicle door lock to change from the unlocked position to the locked position;

[0116] Similarly, controlling the retraction of the vehicle's hidden outer handle according to the handle retraction command can be achieved by sending the handle retraction command to the handle actuator corresponding to the hidden outer handle, causing the handle actuator to actuate and control the internal structure of the hidden outer handle to change from the pre-open position to the fully closed position, that is, controlling the retraction of the hidden outer handle.

[0117] To facilitate understanding, we will now combine... Figure 6 This explanation is provided, but it does not limit the scope of this solution. Figure 6 This is a schematic diagram of emergency braking determination in this embodiment. When the vehicle speed decreases, the vehicle acceleration can be obtained by dividing the change in vehicle speed by the change time. Figure 6As shown, the vehicle acceleration a = (v12-v11) / (T12-T11), where a is a positive value. If the acceleration |a| > threshold A1 (i.e., the preset braking threshold), then it can be determined that the vehicle is performing emergency braking. At this time, the vehicle acceleration can be monitored. If the vehicle speed decreases to less than or equal to the preset judgment threshold within a preset time period (i.e., T22-T12 < preset time period), then it can be determined that the vehicle's operating state meets the preset danger judgment conditions. If the user does not open the door and the vehicle's driving speed v > threshold A2 (i.e., the preset driving threshold), then it can be determined that the user has continued to attempt normal driving. At this time, in order to ensure the user's safety, the door lock and external handle locking commands can be triggered to control the vehicle to lock the doors and retract the hidden external handle.

[0118] This embodiment detects whether the vehicle doors are open. If the vehicle doors are not open and the vehicle speed exceeds a preset driving threshold, a door lock closing command and a handle retraction command are generated. The door lock closing command controls the vehicle to lock the doors, and the handle retraction command controls the retraction of the vehicle's hidden outer handle. Because it detects whether the doors are open after a potential hazard has been identified, and monitors the vehicle speed when the doors are not open, it controls the vehicle to lock the doors and retract the hidden outer handle after the vehicle resumes normal driving, ensuring the safety of the user during normal driving.

[0119] Furthermore, this embodiment of the invention also proposes a storage medium storing a hidden external handle control program, which, when executed by a processor, implements the steps of the hidden external handle control method described above.

[0120] Reference Figure 7 , Figure 7 This is a structural block diagram of the first embodiment of the hidden external handle control device of the present invention.

[0121] like Figure 7 As shown, the concealed external handle control device proposed in this embodiment of the invention includes:

[0122] The monitoring module 10 is used to continuously monitor the operating status of the vehicle when it is powered on.

[0123] The determination module 20 is used to generate door lock control instructions and handle control instructions if the operating state meets the preset danger determination conditions.

[0124] The control module 30 is used to control the vehicle to unlock its doors according to the door lock control command, and to control the hidden outer handle of the vehicle to pop out according to the handle control command.

[0125] This embodiment continuously monitors the vehicle's operating status while it is powered on. If the operating status meets preset hazard judgment conditions, it generates door lock control commands and handle control commands. The door lock control commands unlock the vehicle's doors, and the handle control commands pop out the hidden external handles. Because the vehicle's doors are unlocked and the hidden external handles pop out when the vehicle's operating status meets preset hazard judgment conditions or when an accident occurs, rescue personnel will not face difficulties opening the doors, ensuring timely rescue for occupants and reducing the risk of secondary injury.

[0126] Furthermore, the monitoring module 10 is also used to acquire the triggering status of the airbag sensor in the vehicle when the vehicle is powered on; if the triggering status of the airbag sensor is that the airbag is triggered, then it is determined that the operating status of the vehicle meets the preset danger judgment conditions.

[0127] Furthermore, the monitoring module 10 is also used to continuously monitor the vehicle acceleration when the vehicle is powered on; when the vehicle acceleration is negative and the absolute value of the vehicle acceleration is greater than a preset braking threshold, monitor the vehicle speed; if the speed decreases to less than or equal to a preset judgment threshold within a preset time period, the vehicle's operating state is determined to meet the preset danger judgment conditions.

[0128] Furthermore, the monitoring module 10 is also used to acquire the collected values ​​of the disaster monitoring module in the vehicle when the vehicle is powered on; if the collected value is greater than a preset collection threshold, the vehicle's operating status is determined to meet the preset danger judgment conditions.

[0129] Furthermore, the control module 30 is also used to detect whether the vehicle door is opened; if the vehicle door is not opened and the vehicle speed increases to exceed a preset driving threshold, a door lock closing command and a handle retraction command are generated; the vehicle door is locked according to the door lock closing command, and the hidden outer handle of the vehicle is retracted according to the handle retraction command.

[0130] Furthermore, the control module 30 is also used to acquire the moment of hazard determination, as well as the door unlocking duration and handle pop-out duration corresponding to the vehicle; construct the door lock control moment and handle control moment based on the door unlocking duration, the handle pop-out duration and the moment of hazard determination; control the vehicle to unlock its doors according to the door lock control command based on the door lock control moment, and control the hidden external handle of the vehicle to pop out according to the handle control command based on the handle control moment.

[0131] Furthermore, the control module 30 is also used to set a door lock delay duration and a handle delay duration based on the door unlocking time and the handle pop-out time, wherein the sum of the door unlocking time and the door lock delay duration is less than or equal to the sum of the handle pop-out time and the handle delay duration; determine the door lock control time based on the hazard determination time and the door lock delay duration; and determine the handle control time based on the hazard determination time and the handle delay duration.
