Description

Technical Field

[0001] This invention relates to a control method for a concealed door handle of a vehicle and a vehicle using the control method for the concealed door handle. Background Technology

[0002] In today's cars, concealed door handles are increasingly being used because they can reduce wind resistance to a certain extent, thus improving driving efficiency, and can also enhance the vehicle's premium, stylish, and technological appearance.

[0003] Hidden door handles typically have two opening mechanisms: automatic release and manual triggering. With automatic release, the door handle automatically extends fully to open the door if the vehicle is unlocked or the key is detected nearby, avoiding cumbersome manual operation. With manual triggering, the door handle remains retracted within the door when locked or unlocked; the user needs to lightly touch a designated area to extend the handle, then pull it to open the door. Both automatic and manual triggering mechanisms use a motor to extend the hidden door handle.

[0004] In some cases, the force preventing the concealed door handle from popping out may be greater than the driving force of the motor, causing the concealed door handle to fail to pop out. For example, a common cause is that the concealed door handle may freeze and fail to pop out.

[0005] To address the issue of concealed door handles freezing and failing to pop out, one possible solution is to electrically heat the handle to melt the ice. However, installing heating wires on the door handle is not only prone to damage but also incurred high maintenance costs. For users, electric heating for melting ice is time-consuming and poses electrical risks.

[0006] To address the aforementioned issues, Chinese invention patent application CN116498168A (Patent Document 1) proposes an anti-icing control strategy for concealed door handles. This strategy uses current environmental characteristics and preset environmental verification conditions to prompt the user whether to enter a smart door handle control mode. If the user selects this mode, the door handle remains extended while the vehicle is in motion or locked. If the ambient temperature exceeds a preset temperature while the vehicle is in motion or locked, the smart door handle control mode automatically exits, and the door handle retracts. If the user chooses not to enter the smart door handle control mode, an ice-breaking mode automatically enters when the vehicle is unlocked. This ice-breaking mode uses feedback signals from the door handle to determine if the door handle motor is stalled; if stalling occurs, the door handle retracts and extends. Patent Document 1's technical solution solves the problem of ice forming on the surface of concealed door handles in cold weather, making them difficult to extend. Summary of the Invention

[0007] Patent document 1 provides a technical solution to prevent concealed door handles from freezing and becoming difficult to open, but it still has the following problems:

[0008] (1) As described in paragraphs 0026 and 0027 of Patent Document 1, when manual ice breaking is required due to the door handle being frozen and the motor being stalled, only motor protection logic is added, which does not completely prevent the door handle from freezing in severe weather.

[0009] (2) As described in paragraph 0027 of Patent Document 1, the door handle freezes once and the user needs to manually break the ice before it is determined whether to enter the "intelligent door handle control mode", which is not intelligent enough in use.

[0010] (3) As described in paragraph 0028 of Patent Document 1, after entering the "intelligent door handle control mode," the door handle remains in the extended state regardless of whether the car is in motion or locked, which is unsafe. This is because when the door handle is extended, thieves may mistakenly believe the car is unlocked and try to pull the door, thus increasing the risk of the door handle being damaged and resulting in property loss. In addition, keeping the door handle extended during driving increases wind resistance, and the poor design can also cause noise, vibration, and harshness (NVH) problems.

[0011] (4) Patent Document 1 Figure 2 The step of "automatically entering de-icing mode to remove remaining ice after the outside temperature remains above 0℃ for 1.5-2 hours" does not consider the scenario where the outside temperature remains below 0℃. If the outside temperature remains below 0℃, the anti-icing control strategy cannot continue to operate, indicating a design flaw.

[0012] In view of the problems existing in the prior art represented by Patent Document 1, the present invention provides a control method for a hidden door handle, (1) which can monitor weather information in real time and control the action of the door handle to avoid the door handle freezing and eliminates the need for manual ice breaking; (2) which avoids the risk of the hidden door handle motor stalling and motor damage; (3) the hidden door handle is not always in the unfolded mode when driving and locking the car, thus ensuring the safety of the vehicle; and (4) there is no design flaw such as the anti-icing control strategy failing to continue to operate.

[0013] To address the aforementioned technical problems, the present invention provides a control method for a concealed door handle of a vehicle, comprising: a step of the vehicle's temperature sensor measuring the external temperature; a step of the vehicle's rain and snow sensor detecting whether it is raining or snowing outside; a step of the vehicle's communication unit obtaining a weather forecast of the vehicle's location from the outside; and a step of the vehicle's control unit deciding whether to retract or extend the concealed door handle, wherein, when the vehicle is in motion, the control unit decides whether to retract the concealed door handle based on the measured external temperature and the detected rain or snow, and when the vehicle is parked, the vehicle's control unit decides whether to retract or extend the concealed door handle based on the measured external temperature, the detected rain or snow, and the weather forecast information.

[0014] Preferably, when the vehicle is in motion, if the external temperature is below a predetermined temperature threshold and rain or snow is detected, the hidden door handle is popped out and then retracted at a certain frequency based on the measured external temperature. If the external temperature is not lower than the temperature threshold, the hidden door handle is retracted.

[0015] Preferably, when the vehicle is parked, the hidden door handle pops out when the outside temperature is below a predetermined temperature threshold and rain or snow is detected. When the outside temperature is below the predetermined temperature threshold and no rain or snow is detected, the rain and snow sensor is activated at a certain frequency based on the measured outside temperature, according to the information in the weather forecast indicating that rain or snow will occur within a predetermined time. When the activated rain and snow sensor detects rain or snow, the hidden door handle pops out.

[0016] Preferably, the concealed door handle is retracted when both the external temperature and the minimum temperature within the specified future time in the weather forecast are not lower than the temperature threshold; the concealed door handle is retracted when the weather forecast indicates no rain or snow within the specified future time; and the concealed door handle is retracted when the activated rain and snow sensor does not detect rain or snow.

[0017] Preferably, if the time during which the concealed door handle is extended does not exceed a predetermined time threshold and the vehicle is not started within the extended time, the concealed door handle is kept extended. After the vehicle is started again, the control to retract or extend the concealed door handle to prevent freezing is re-entered. If the time during which the concealed door handle is extended exceeds the predetermined time threshold, the concealed door handle is retracted when the vehicle meets the predetermined conditions.

[0018] Furthermore, the present invention provides a vehicle with a concealed door handle, comprising: a temperature sensor for measuring the external temperature of the vehicle; a rain / snow sensor for detecting whether it is raining or snowing outside the vehicle; a communication unit for obtaining weather forecasts of the vehicle's location from outside the vehicle; and a control unit for deciding whether to retract or extend the concealed door handle, the control unit controlling whether to retract the concealed door handle when the vehicle is in motion, based on the measured external temperature and the detected rain or snow, and whether to retract or extend the concealed door handle when the vehicle is parked, based on the measured external temperature, the detected rain or snow, and the weather forecast information.

[0019] Preferably, the control unit performs the control so that when the vehicle is in motion, if the external temperature is lower than a predetermined temperature threshold and rain or snow is detected, the hidden door handle is popped out and then retracted at a certain frequency based on the measured external temperature; and if the external temperature is not lower than the temperature threshold, the hidden door handle is retracted.

[0020] Preferably, the control unit controls the vehicle to pop out the hidden door handle when the vehicle is parked and the outside temperature is below a predetermined temperature threshold and rain or snow is detected. When the outside temperature is below the predetermined temperature threshold and no rain or snow is detected, the rain and snow sensor is activated at a certain frequency based on the measured outside temperature, according to the information in the weather forecast indicating that rain or snow will occur within a predetermined time. When the activated rain and snow sensor detects rain or snow, the hidden door handle pops out.

[0021] Preferably, the control unit performs control such that when the external temperature and the minimum temperature within the specified future time in the weather forecast are both not lower than the temperature threshold, the hidden door handle is retracted; when the weather forecast indicates that there will be no rain or snow within the specified future time, the hidden door handle is retracted; and when the activated rain and snow sensor does not detect rain or snow, the hidden door handle is retracted.

[0022] Preferably, the control unit controls the hidden door handle to remain in the popped-out state if the time when the hidden door handle is popped out exceeds a predetermined time threshold and the vehicle has not been started within the popped-out time, and to retract or pop out the hidden door handle to prevent freezing after the vehicle is started again, and to retract the hidden door handle when the vehicle meets the predetermined conditions if the time when the hidden door handle is popped out exceeds the predetermined time threshold.

[0023] The vehicle concealed door handle control method according to the present invention, and the vehicle using the concealed door handle control method, can intelligently and automatically prevent the door handle from freezing by performing different control processes under different vehicle conditions, without requiring manual de-icing after the door handle is frozen, and without requiring any user attention. Furthermore, it also avoids the need to extend the door handle for an extended period to prevent it from freezing. Attached Figure Description

[0031] Hereinafter, embodiments of the vehicle concealed door handle control method of the present invention will be described with reference to the accompanying drawings.

[0032] Figure 1 The image shows the exterior of a vehicle equipped with concealed door handles. For example... Figure 1 As shown, the vehicle 100 includes multiple concealed door handles 101 corresponding to the doors, a temperature sensor 102 for measuring the outside temperature of the vehicle, and a rain / snow sensor 103 for detecting precipitation. Furthermore, the vehicle 100 can interact with the server 300 via the network 200, uploading vehicle data to the server 300 or retrieving necessary data from the server 300.

[0033] The vehicle 100 can be an internal combustion engine-driven vehicle, an electric vehicle, or a hybrid vehicle. As long as it is equipped with a hidden door handle and is configured to execute the hidden door handle control method of the present invention, the present invention can be applied.

[0034] The concealed door handle 101 is a door handle that retracts to blend seamlessly with the door surface and extends outwards, allowing a person to pull it to open the door. It is located inside the door. Figure 1 A motor (not shown) can pop out or retract the concealed door handle 101 via a push rod, connecting mechanism, etc. The concealed door handle 101 can be in the form of popping out horizontally as a whole, or in the form of one end of the door handle popping out while the other end retracts into the door panel.

[0035] The temperature sensor 102 is preferably located in a position that is not easily affected by the heat generated by the vehicle itself, such as in the front bumper air intake grille. Here, the temperature sensor 102 refers to a sensor used to measure the external air temperature of the vehicle required for implementing the control method of the concealed door handle of the present invention. The vehicle 100 may also be equipped with other temperature sensors such as an interior temperature sensor.

[0036] The rain and snow sensor 103 is based on the principle of liquid conductivity. It uses electrodes to detect the presence of water to determine whether it is raining or snowing. For example, it is installed at the base of the rearview mirror inside the vehicle, located on the outside of the windshield. Hereinafter, rain and snow will sometimes be referred to collectively as precipitation.

[0037] Network 200 can be provided by the vehicle's onboard SIM card linked to the vehicle's wireless communication module, or by the vehicle's Wi-Fi router with a wireless internet card, or by the vehicle's built-in vehicle networking system. This network 200 can be the internet or a dedicated network, as long as it can obtain the necessary data from server 300.

[0038] Server 300 refers to the infrastructure capable of providing various data required by vehicle 100, which can be provided by government departments, vehicle manufacturers, or third-party companies. For example, in this invention, weather forecast information needs to be obtained from server 300, which could be a server used by a meteorological bureau to issue weather forecast information.

[0039] Vehicle 100 has Figure 1 The control units, such as the central processing unit (CPU) and microcontroller (MCU), not shown, are used to execute the control method for the concealed door handle of the present invention. Specifically, actions such as collecting data from the temperature sensor 102 and the rain and snow sensor 103, acquiring data from the server 300, and controlling the pop-up and retraction of the concealed door handle 101 are all controlled and executed by the control units such as the CPU and MCU.

[0040] The prerequisite for door handles to freeze is a temperature below freezing and precipitation. The methods to prevent freezing vary depending on the vehicle's condition. Therefore, the idea behind the concealed door handle control method of this invention is as follows: When the vehicle is in motion, the pop-up and retraction of the concealed door handle are controlled based on the ambient temperature and weather information (whether there is precipitation) to prevent the concealed door handle from freezing; when the vehicle is parked, the decision to retract or pop up the concealed door handle is made based on the weather forecast and real-time weather conditions to prevent the concealed door handle from freezing, thereby solving the problems existing in the prior art. See below for reference. Figures 2-6 The method for controlling the concealed door handle of the present invention will be described in detail.

[0041] Figure 2 This demonstrates the different control procedures to follow depending on the vehicle's status after activating the hidden door handle antifreeze control.

[0042] In a specific mode, the vehicle can activate the hidden door handle antifreeze control to execute the hidden door handle control method of the present invention. For example, most vehicles have a Winter Mode, which is the specific mode described above. If the vehicle does not have a dedicated Winter Mode, the user can also manually activate the hidden door handle antifreeze control. When the hidden door handle antifreeze control is activated, the following steps are executed: Figure 2 In step S0, as shown, the CPU, MCU, and other control units of vehicle 100 determine the vehicle's state based on vehicle information such as the operating status of the vehicle's power unit and whether it is in P gear with the engine off. This state includes both a driving state (the vehicle is in motion) and a parked state (the vehicle is off). When in a driving state, control flow A is executed. Details of control flow A are provided below. Figure 3 , Figure 4 Explanation. When the vehicle is in park, control flow B is executed. Details of control flow B are provided below. Figure 5 , Figure 6 illustrate.

[0043] When it is determined in step S0 that vehicle 100 is in a driving state, execute... Figure 3 The control flow A is shown below. In flow A, firstly, in step S10, the real-time external temperature data of the vehicle is acquired by the temperature sensor 102. The data measured by the temperature sensor 102 is transmitted to the control unit (control unit), which determines whether the real-time external temperature of the vehicle is lower than a low temperature threshold, which can be set to 2°C for example. Of course, the low temperature threshold is not limited to 2°C and can be any temperature slightly higher than the freezing point. When the real-time external temperature of the vehicle is lower than the low temperature threshold, step S11 is executed. When the real-time external temperature of the vehicle is higher than or equal to the low temperature threshold, it is determined that there is no risk of the hidden door handle 101 freezing, and at this time, the hidden door handle 101 is put into the retracted state.

[0044] In step S11, the vehicle 100 determines the weather conditions, i.e., whether there is precipitation, based on the detection result of the rain and snow sensor 103. If there is no precipitation (No in step S11), the temperature is low but there is no water, so there is no risk of the concealed door handle 101 freezing. In this case, step S11 is repeated until the rain and snow sensor 103 detects precipitation (Yes in step S11).

[0045] If the rain and snow sensor 103 detects precipitation, step S12 is executed, in which the action of popping out and retracting the concealed door handle 101 is performed at different frequencies depending on the temperature. By repeatedly performing the pop-out and retraction action, the concealed door handle 101 can be prevented from freezing.

[0046] As an example of a concealed door handle 101 that pops up at different frequencies depending on the temperature, such as Figure 4 As shown in the chart, when the temperature is between 0 and 2°C, the concealed door handle 101 pops out once every hour to prevent icing; when the temperature is between -5 and 0°C, it pops out once every 30 minutes; when the temperature is between -10 and -5°C, it pops out once every 15 minutes; and when the temperature is below -10°C, it pops out once every 6 minutes. The concealed door handle 101 remains popped out during periods of heavy snow and / or freezing weather. Heavy snow and freezing weather can be defined using common weather forecasts, such as snowfall exceeding 3.0 mm in 12 hours, or can be customized as needed.

[0047] Figure 4 The diagram shows an example of various temperature ranges and pop-up frequencies, which can be adjusted appropriately according to actual conditions. For example, to reduce the risk of icing, the concealed door handle 101 can be popped up at a higher frequency, but this consumes more power. Conversely, to save power, the concealed door handle 101 can be popped up at a lower frequency, but this increases the risk of icing. The activation frequency and the corresponding temperature range can be adjusted accordingly.

[0048] In addition, the hidden door handle 101 may not pop out completely while the vehicle is in motion, but only partially, for example, 50%, to prevent accidents.

[0049] By executing control process A in the aforementioned concealed door handle antifreeze control while the vehicle is in motion, the concealed door handle 101 pops out at different frequencies according to different temperatures, especially in low temperatures and during precipitation, thus preventing the door handle from freezing. This avoids the door handle from freezing, unlike prior art, such as Patent Document 1, which requires manual de-icing after the door handle has frozen. Furthermore, it intelligently and automatically prevents the door handle from freezing without any user intervention. And unlike prior art, it avoids prolonged door handle pop-out to prevent freezing.

[0050] exist Figure 2 In step S0, when it is determined that vehicle 100 is in a parked state, execute... Figure 5 The control flow B is shown. In this flow, if the vehicle 100 is turned off by shifting to P gear while the vehicle 100 is already running, it is determined that the vehicle 100 is in a parked state.

[0051] In control flow B, similar to control flow A, the real-time external vehicle temperature data measured by temperature sensor 102 is first acquired in step S20. The data measured by temperature sensor 102 is transmitted to the control unit, which determines whether the real-time external vehicle temperature is below a low-temperature threshold, which can be set to 2°C. Of course, the low-temperature threshold is not limited to 2°C and can be any temperature slightly higher than the freezing point. When the real-time external vehicle temperature is higher than or equal to the low-temperature threshold, step S21 is executed; when the real-time external vehicle temperature is lower than the low-temperature threshold, step S22 is executed.

[0052] If the real-time outside temperature of the vehicle is higher than or equal to the low-temperature threshold, then there is no risk of the concealed door handle 101 freezing. Therefore, in step S21, the vehicle 100 obtains the lowest temperature information from the weather forecast from the server 300 via the network 200 to further determine whether there is a risk of the concealed door handle 101 freezing in the near future. In step S21, if the lowest temperature shown in the weather forecast is higher than or equal to the low-temperature threshold, then there is no risk of the concealed door handle 101 freezing in the near future, and the concealed door handle 101 is then in the retracted state. The low-temperature threshold here can be the same as the low-temperature threshold in step S20, or it can be a different value.

[0053] If, in step S21, it is determined that the lowest temperature shown in the weather forecast is below the low-temperature threshold, then the concealed door handle 101 is at high risk of freezing in the event of precipitation. Therefore, in step S23, further information on whether it will be rainy or snowy is obtained from the weather forecast. If it is not rainy or snowy in the near future, then the temperature is low but there is no water, so the concealed door handle 101 is not at risk of freezing, and the concealed door handle 101 is then placed in the retracted state.

[0054] If it is known in step S23 that there will be rain and snow in the near future, the temperature will be low and there will be precipitation, so the hidden door handle 101 is at greater risk of freezing. At this time, step S24 is executed to activate the rain and snow sensor 103 at different frequencies according to different temperatures.

[0055] As an example of rain and snow sensor 103 activating at different frequencies based on different temperatures, such as Figure 6 As shown in the chart, when the temperature is between 0 and 2°C, the rain and snow sensor 103 activates every 2 hours to detect precipitation; when the temperature is between -5 and 0°C, it activates every 1 hour; when the temperature is between -10 and -5°C, it activates every 15 minutes; and when the temperature is below -10°C, it activates every 6 minutes. When the forecast is for heavy snow and / or freezing weather, the rain and snow sensor 103 remains operational. Heavy snow and freezing weather can be defined using common weather forecasts, such as heavy snow being defined as snowfall exceeding 3.0 mm in 12 hours, or can be customized as needed.

[0056] Figure 6 The diagram shows an example of various temperature ranges and activation frequencies, which can be adjusted appropriately according to actual conditions. For example, to reduce the risk of icing, the rain and snow sensor 103 can be activated at a higher frequency, but this consumes more power. Conversely, to save power, the rain and snow sensor 103 can be activated at a lower frequency, but this increases the risk of icing. The activation frequency and the corresponding temperature range can be adjusted accordingly.

[0057] In step S25, the vehicle 100 determines the weather conditions, i.e., whether there is precipitation, based on the detection results of the rain and snow sensor 103. If there is no precipitation, the temperature is low but there is no water, so there is no risk of the concealed door handle 101 freezing. At this time, the concealed door handle 101 is in the retracted state. No precipitation indicates sunny, cloudy, or other weather without rain or snow.

[0058] If the judgment result in step S25 is precipitation, then the temperature is low and there is water, so the risk of the hidden door handle 101 freezing is high. At this time, the hidden door handle 101 is popped out to prevent it from freezing.

[0059] Returning to the description of step S20, if the real-time external temperature of the vehicle measured in step S20 is lower than the low temperature threshold, step S22 is executed.

[0060] In step S22, the rain and snow sensor 103 detects whether precipitation is currently occurring. If precipitation is occurring, the temperature is low, and there is a high risk of the concealed door handle 101 freezing, requiring the concealed door handle 101 to be popped out to prevent freezing. If no precipitation is detected, step S24 and subsequent steps are performed as described above.

[0061] To avoid safety issues caused by the door handle being extended for an extended period, a further control procedure C is required in such cases.

[0062] like Figure 7 As shown, in control flow C, step S30 first determines whether the door handle pop-out time exceeds a time threshold, which can be set to, for example, 12 hours. Of course, the time threshold is not limited to 12 hours and can be any appropriate duration. If step S30 determines that the door handle pop-out time exceeds the time threshold, the vehicle 100 is switched to an away mode. In away mode, the concealed door handle 101 retracts when the vehicle 100 meets specified conditions. For example, when the external temperature measured by the temperature sensor 102 exceeds a specified temperature for a continuous period, and the light sensor of the vehicle 100 can receive light normally, the door handle is retracted.

[0063] If it is determined in step S30 that the door handle popping out does not exceed the time threshold, then step S31 is executed.

[0064] In step S31, it is determined whether the vehicle has been started. If the vehicle has not been started, the door handle remains in the pop-out state until a time threshold is exceeded, at which point the vehicle 100 is transferred to the away mode. If the vehicle has been started, it is restarted. Figures 3-6 The concealed door handle antifreeze control shown is used to prevent the concealed door handle 101 from freezing.

[0065] By executing control process B in the aforementioned concealed door handle antifreeze control when the vehicle is parked, the concealed door handle 101 pops out in situations where the current temperature is low and it is raining or about to rain, or where the current temperature is high but the predicted temperature is low and it is about to rain, thus preventing the door handle from freezing. When the current temperature is high, the door handle retracts directly. Therefore, the door handle is prevented from freezing, unlike prior art represented by Patent Document 1, which requires manual de-icing after the door handle has frozen. Furthermore, it intelligently and automatically prevents the door handle from freezing without any user intervention.

[0066] Furthermore, when the concealed door handle 101 is extended for an extended period, switching the vehicle 100 to the "away" mode allows the concealed door handle 101 to be retracted at an appropriate time, improving the safety of the vehicle 100 and preventing the door handle from being extended for an extended period, which could lead to safety hazards, unlike existing technologies.

[0067] The above explains the control method for the vehicle's concealed door handles and the vehicles using this control method. Different control procedures are implemented depending on the vehicle's operating state. Specifically, when the vehicle is in motion, the retraction and extension of the concealed door handles are controlled based on the ambient temperature and weather information (whether it is raining) to prevent them from freezing. When the vehicle is parked, the weather forecast is used as a reference, and real-time weather conditions are a necessary condition to determine whether to extend or retract the concealed door handles to prevent them from freezing. This intelligently and automatically prevents the door handles from freezing, eliminating the need for manual de-icing after the handles have frozen and requiring no user intervention. Furthermore, it avoids the need to extend the door handles for extended periods to prevent them from freezing.

When the external temperature is below a predetermined temperature threshold and rain or snow is detected, the system will, based on the measured external temperature, perform the action of popping out the concealed door handle and then retracting it at a certain frequency. When the external temperature is not lower than the temperature threshold, the concealed door handle retracts.

8. The vehicle as described in claim 6, characterized in that: The control unit performs the control. This ensures that when the vehicle is in a parked state, When the external temperature is below a specified temperature threshold and rain or snow is detected, the concealed door handle pops out. When the external temperature is lower than the specified temperature threshold and no rain or snow is detected, the rain and snow sensor is activated at a certain frequency based on the information in the weather forecast indicating that rain or snow will occur within a specified time in the future, according to the measured external temperature. When the activated rain and snow sensor detects rain or snow, the hidden door handle pops out.

9. The vehicle as described in claim 8, characterized in that: The control unit performs the control. The concealed door handle retracts when both the external air temperature and the lowest temperature within a specified future timeframe in the weather forecast are not lower than the temperature threshold. When the weather forecast indicates no rain or snow within the specified future period, the concealed door handle retracts. When the activated rain and snow sensor does not detect rain or snow, the concealed door handle retracts.

10. The vehicle as described in claim 8 or 9, characterized in that: The control unit controls the retraction or ejection of the hidden door handle to maintain its extended state if the time during which the hidden door handle is extended does not exceed a predetermined time threshold and the vehicle is not started within that extended time. The control unit then re-enters the freeze-prevention mechanism when the vehicle is started again. And if the time it takes for the concealed door handle to pop out exceeds a predetermined time threshold, the concealed door handle will retract when the vehicle meets the predetermined conditions.
