Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese application with application number 2023113047556 filed on October 9, 2023 and application name “Locking control method, device, vehicle and storage medium”. Technical Field

[0003] The present application relates to the field of vehicle control technology, and more specifically, to a locking control method, device, vehicle and storage medium. Background Art

[0004] With the continuous development of society and the gradual expansion of the automobile consumer group, the comfort and convenience of automobiles have become increasingly important. Humanization and intelligence are the mainstream ideas of automobile development. The intelligent active locking function is a basic function developed by most smart cars. That is, when the driver gets out of the car with the key and closes all the doors, the vehicle will automatically locate the key position and automatically lock after judging that the key has left. The advantage of the intelligent active locking function is that it realizes a non-sensitive smart car experience, saving the trouble of the driver taking out the key from the bag to manually lock the car.

[0005] However, the inventors found in their research that the triggering condition for the current intelligent active locking function is that all doors are completely closed. In the scenario where the vehicle is equipped with sliding doors, scissor doors, or swing doors, it takes about 5-10 seconds for the sliding doors, scissor doors, or swing doors to open and close. If the owner walks too fast and is already far away from the vehicle during the closing process of the sliding doors, scissor doors, or swing doors (i.e., the sliding doors, scissor doors, or swing doors have not been completely closed at this time), the key carried by the owner may be too far away from the vehicle and the key cannot be found, resulting in the failure of the intelligent active locking function of the vehicle, the failure to lock the vehicle, and the risk of the vehicle being stolen. That is, the current intelligent active locking function has a low key search success rate and a high locking failure rate for vehicles equipped with sliding doors, scissor doors, or swing doors. In other words, for vehicles equipped with sliding doors, scissor doors, or swing doors, the current key search success rate and locking success rate of the intelligent active locking function are low.

[0006] The inventors also found in their research that key positioning is a search by the vehicle-mounted detection antenna through 125 kilohertz (KHz) electromagnetic waves. If the key is located near a mobile phone / computer / charging station, the key positioning will be affected by electromagnetic compatibility (EMC) low-frequency interference, and there may be a situation where the key cannot be found. The current intelligent active locking function only searches once to determine whether to lock the vehicle, that is, if the key is found, the vehicle is locked, and if the key is not found, the vehicle is not locked. Once the above-mentioned EMC interference occurs and the key is not found, the intelligent active locking function will fail, the vehicle will fail to lock, and the risk of vehicle theft will be caused. In other words, the key search of the current intelligent active locking function has poor anti-interference, resulting in a low key search success rate and locking success rate. Summary of the invention

[0007] The embodiments of the present application propose a locking control method, device, vehicle and storage medium to improve the problems of poor anti-interference performance of key search, low key search success rate and low locking success rate of the current intelligent active locking function.

Compared with the current intelligent active locking function that searches for keys after all the doors are actually completely closed, the present application determines in advance that all the doors are closed during the process of all the doors being closed, and searches for keys in advance before the doors are actually closed, so as to avoid the owner carrying the keys away from the vehicle and causing the vehicle to be unable to search for the keys, thereby improving the key search success rate, avoiding the failure of the vehicle to lock the vehicle due to the failure of the intelligent active locking function of the vehicle, improving the locking success rate, reducing the risk of vehicle theft, and improving vehicle safety. In addition, by searching for the key within a specified time range, it is possible to avoid the situation where the key cannot be found due to EMC low-frequency interference when it is near devices such as mobile phones / computers / charging piles. This is because EMC low-frequency interference occurs periodically or occasionally and for a short period of time and will not continue to appear. This can improve the anti-interference ability of the key search, thereby improving the key search success rate and locking success rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0027] See also Figure 1 , Figure 1 1 is a block diagram of a locking control system provided by an embodiment of the present application. The locking control system 100 is used to implement an intelligent active locking function according to the locking control method described below. The locking control system 100 can be applied to a vehicle, which can be, but is not limited to, a gasoline vehicle, an electric vehicle, or a hybrid vehicle. Figure 1 As shown, the locking control system 100 includes an integrated body control module (IBCM) 110, a door switch 120, a controller 130, a detection antenna 140, a radio frequency receiver (RFP) 150, a smart remote control key 160, and a door lock motor 170.

[0028] The door switch 120 may be an ajar switch (commonly referred to as an AJAR switch in the art). The door AJAR switch refers to a switch protruding next to the latch of the vehicle body when the door is opened. The door AJAR switch can be pressed in by hand. All vehicle doors are connected to corresponding door switches, and each door corresponds to one door switch.

[0029] The controller 130 is used to output a control signal about the controlled door, for example, a closing signal "open→closing" or an open signal "open" or a closed signal "closed". The controller 130 can inform the IBCM 110 of the door status of the door controlled by the controller 130 through a vehicle bus controller area network (CAN) signal. For example, the closing signal "open→closing" indicates that the door status of the door is closing.

[0030] In some embodiments, the vehicle may only include an electric door that is in a closing state, where the electric door refers to a door that can be controlled by the controller. In this embodiment, the controller 130 may be used to control the electric door.

[0031] In some other embodiments, the vehicle may include a first type of door and a second type of door. The first type of door is a door that does not have a closing state. The first type of door may include but is not limited to a mechanical door or an electric door that only has an open state and a closed state, such as a hinged door. The second type of door is an electric door that has a closing state. The second type of door may include but is not limited to a scissor door, a sliding door, a swing door, etc. It should be noted that an electric door that has a closing state also has an open state and a closed state. In this embodiment, the controller 130 is used to control the second type of door.

[0032] The detection antenna 140 may be an intelligent detection antenna, and the detection antenna 140 may send 125 kilohertz (KHz) electromagnetic waves to search for keys. The detection antenna 140 may include a detection antenna located inside the vehicle and a detection antenna located outside the vehicle. The specific installation position of the detection antenna and the electromagnetic wave signal range may be deployed according to actual needs and are not specifically limited here.

[0033] The RFP 150 is used to receive the electromagnetic wave signal sent by the key, for example, the electromagnetic wave signal of 433.92 megahertz (MHz). The range of the electromagnetic wave signal that the radio frequency receiving module can actually receive can be set according to actual needs.

[0034] The smart remote control key 160 (hereinafter referred to as the key) is used to start the vehicle or open or close the door. When the smart remote control key 160 receives the 125KHz electromagnetic wave (key search signal) sent by the detection antenna 140, it can emit a 433.92MHz electromagnetic wave.

[0035] The door lock motor 170 is connected to the door switches 120 of all the vehicle doors respectively. The door lock motor 170 is used to control the opening and closing states of the door switches 120 connected thereto, such as the open state and the closed state.

[0036] The IBCM 110 is an electronic control unit (ECU) for executing the intelligent active locking function, that is, the IBCM 110 may be the execution subject of the locking control method described below. Figure 1 As shown, the IBCM 110 is connected to the door lock motor 170, and the door lock motor 170 is respectively connected to the door switches 120 of all the doors. The IBCM 110 can be used to determine whether the door is opened or closed according to the open or closed state of the door switch 120 of the door.

[0037] IBCM 110 is also connected to controller 130, and IBCM 110 can obtain signals representing the door status of the vehicle door from controller 130, for example, a signal "open" representing that the vehicle door is open, a signal "open→closing" representing that the second type of vehicle door is closing, and a signal "closed" representing that the second type of vehicle door is closed.

[0038] IBCM 110 is also connected to detection antenna 140 and RFP 150 respectively. IBCM 110 can hard-wire the smart detection antenna to send electromagnetic waves of a preset search frequency (e.g., 125KHz) for key search. When the smart remote control key 160 receives the key search signal of the preset search frequency, it immediately sends an electromagnetic wave signal of a preset feedback frequency (e.g., 433.92MHz), which is received by RFP 150. After RFR 150 receives the position signal of the smart remote control key 160, it feeds back the key position to IBCM 110 through a private Local Interconnect Network (LIN) line. After receiving the signal, IBCM 110 can know the real-time position of the smart remote control key 160.

[0039] In some embodiments, the locking control system 100 may also include a vehicle-mounted wireless charging module (Wireless Charging Module, WCM for short), which is used to wirelessly charge electronic devices, for example, the WCM may be used to wirelessly charge electronic devices such as smart phones, smart bracelets, or tablet computers. The IBCM 110 is also connected to the WCM to control whether the WCM works or not.

[0040] The key search function involved in the intelligent active locking function implemented by IBCM 110 includes the following three modes:

[0041] 1. The first search mode: The detection antennas inside and outside the car work at the same time, and the key is searched once every first preset time interval (for example, 500 milliseconds). IBCM can know in real time whether the legal key is in the effective detection area inside and outside the car. In addition, during the key search, that is, during the operation of the detection antenna inside the car, in order to avoid the EMC low-frequency interference of WCM affecting the success of the key search, it is necessary to actively shield the WCM function, that is, it is necessary to control the on-board wireless charging module not to work to prevent the key from being placed directly above the WCM, resulting in the key position being unable to be identified, affecting the key search function. The first search mode requires turning on the detection antennas inside and outside the car at the same time and the detection frequency is high, so the power consumption is high, which can also be called a high-power search mode.

[0042] 2. Second search mode: Determine not to lock the vehicle, control the detection antennas inside and outside the vehicle to not work, and do not search for keys. Since the key search function is stopped, there is no need to search for keys inside the vehicle. In order to provide the user with wireless charging function, the WCM function is not prohibited in the third search mode, that is, the vehicle-mounted wireless charging module can be controlled to work. Since the second search mode does not search for keys, the second search mode can also be called a prohibited search mode.

[0043] 3. The third search mode is a low-power search mode: the detection antenna inside the car is controlled to stop working, and the detection antenna outside the car searches once every second preset time (for example, 750 milliseconds). The IBCM can know in real time whether the legitimate key is in the effective detection area outside the car. In addition, during the key search, since there is no need to search the key inside the car, in order to provide the user with wireless charging function, the WCM function is not prohibited in the third search mode, that is, the vehicle-mounted wireless charging module can be controlled to work. In the third search mode, the detection frequency of the detection antenna outside the car is lower than that in the first search mode, so the power consumption is less than that in the first search mode, which can also be called a low-power search mode.

[0044] Regarding how to use the above three modes to realize the intelligent active locking function, please refer to the locking control method below.

[0045] The locking control method in the embodiment of the present application can be applied to the IBCM in the above-mentioned locking control system or the locking control device or vehicle described below.

[0046] See also Figure 2 , Figure 2 1 is a flow chart of a locking control method provided in an embodiment of the present application. The locking control method may include step S110 and step S120. In this embodiment, the vehicle involved is only equipped with electric doors in a closing state, such as scissor doors, sliding doors or swing doors, etc. For a detailed description, please refer to the above-mentioned relevant parts.

[0047] Step S110: In response to all doors of the vehicle being closed, searching for a key inside or outside the vehicle within a specified time range, wherein all doors of the vehicle are electric doors in a closing state.

[0048] In the embodiment of the present application, the key located inside or outside the vehicle refers to the smart remote control key. In addition, the key being searched refers to the legal key of the vehicle, that is, the key that is compatible with the vehicle and can be used to control the vehicle after passing the legality verification. The key located inside the vehicle refers to the key located within the effective area inside the vehicle, and the key located outside the vehicle refers to the key located within the effective area outside the vehicle. The effective area can be determined according to actual needs, for example, according to the electromagnetic wave coverage of the key. In the effective area, the key can receive the key search signal sent by the vehicle. For example, the key search signal can be an electromagnetic wave of the aforementioned preset search frequency (for example, 125KHz). In the effective area, the key can also send a search feedback signal to the vehicle. For example, the search feedback signal can be an electromagnetic wave of the aforementioned preset feedback frequency (for example, 433.92MHz).

[0049] As mentioned above, the inventor found in the research that when the key is near the mobile phone / computer / charging pile, the key positioning will be affected by the electromagnetic compatibility EMC low-frequency interference, which may result in the key being unable to be searched. In order to overcome this defect, the inventor found in the in-depth research that the above-mentioned EMC low-frequency interference occurs periodically or occasionally, and the EMC low-frequency interference occurs for a short time and usually does not continue to appear for a period of time. Based on this discovery, the inventor designed a technical means to perform key searches multiple times within a specified time range in the preliminary search stage and to determine whether to lock the vehicle based on the search results within the specified time range in the further precise search stage, so as to ensure that the key can be accurately searched, improve the success rate and accuracy of the key search, and avoid the failure of the intelligent active locking function.

[0050] In response to receiving a signal indicating that the door is closing, for example, receiving a door status signal "open→closing" output by the controller, the IBCM can set the signal "closing" indicating that the door is closing to a closed signal "closed". In response to the closed signal "closed", the IBCM starts searching for keys inside or outside the vehicle within a specified time range. The longer the specified time, the higher the key search success rate and accuracy, and accordingly, the more power is consumed. Therefore, the specified time can be pre-set according to actual needs. For example, the specified time can be 1500 milliseconds. It should be noted that the specified time should be set to be greater than or equal to the product of the number threshold and the first preset time below. For example, if the number threshold is 3 times and the first preset time is 500 milliseconds, the specified time should be set to be greater than or equal to 3*500=1500 milliseconds. By searching for the key within a specified time range, you can avoid the situation where the key cannot be found due to EMC low-frequency interference when it is near devices such as mobile phones / computers / charging piles, because EMC low-frequency interference occurs periodically or occasionally and for a short time, and will not appear continuously.

[0051] Specifically, the IBCM enters the first search mode in response to all doors of the vehicle being closed, that is, the detection antenna inside and outside the vehicle is controlled to search for the key once every first preset time interval until the key located inside or outside the vehicle is found, or until the number of consecutive searches reaches the number threshold and the key is still not found. Among them, the shorter the first preset time and the more the number threshold, the higher the key search success rate and accuracy, and accordingly, the more power consumption is required. Therefore, the first preset time and the number threshold can be pre-set according to actual needs. For example, the first preset time can be 500 milliseconds, and the number threshold can be three times. If the key has not been searched for three consecutive times, it is determined that the key has not been searched. By searching for the key multiple times, it can be avoided that the key is not found due to EMC low-frequency interference when it is near devices such as mobile phones / computers / charging piles, because EMC low-frequency interference occurs periodically or occasionally and occurs for a short time, and will not appear continuously.

[0052] Step S120: Determine whether to lock the vehicle based on the search results.

[0053] The inventor found in the research that the current intelligent active locking function locks the vehicle when the key is searched, and does not lock the vehicle when the key is not searched. For the scenario where the user is talking to other people outside the vehicle near the vehicle, the current intelligent active locking function will repeatedly lock and unlock the vehicle, resulting in frequent automatic locking and unlocking, which not only consumes vehicle resources but also may make the user feel bored. That is, the current intelligent active locking function uses the same judgment logic for whether to lock the vehicle for all scenarios, resulting in the inability of the intelligent active locking function to flexibly respond to various scenarios, poor flexibility and low locking accuracy. Therefore, in the embodiment of the present application, a key search mode corresponding to the search result is used to determine whether to lock the vehicle, and different key search modes can be used for different search results to further determine whether to lock the vehicle. Compared with the current intelligent active locking function that locks the vehicle when the key is searched and does not lock the vehicle when the key is not searched, using different key search modes for different search results can improve the flexibility and accuracy of the intelligent active locking function, so that the intelligent active locking function can be applied to various scenarios.

[0054] Specifically, in an embodiment of the present application, the search result "searched for the key inside the car" corresponds to the second search mode, the search result "searched for the key outside the car" corresponds to the first search mode, and the search result "failed to search for the key for multiple consecutive times (i.e., the above-mentioned number threshold)" corresponds to the third search mode.

[0055] If the search result shows that the key is found inside the car, there is a high probability that someone is inside the car, so the second search mode can be entered, that is, determine not to lock the vehicle, and at the same time control the detection antennas inside and outside the car to stop working.

[0056] If the search result is that the key is found outside the vehicle, the first search mode is maintained, and the detection antennas inside and outside the vehicle are controlled to search for the key once every first preset time interval. At this time, the timing is started and the first timing duration is obtained.

[0057] When the first timing duration is less than the duration threshold and the key outside the vehicle is searched, the user may be talking to other people outside the vehicle near the vehicle. In this case, it can be temporarily determined not to lock the vehicle, and the detection antennas inside and outside the vehicle can continue to be controlled to search for keys, so that frequent locking and unlocking when the user is talking to other people will cause excessive power consumption and make the user feel bored. Among them, the longer the duration threshold, the higher the search accuracy, and accordingly, the more power consumption is consumed. Therefore, the duration threshold can be set according to actual needs. For example, the duration threshold can be 10 minutes.

[0058] When the first timing duration is less than the duration threshold and no key is found, it indicates that the user is away from the vehicle and intends to lock the vehicle. At this time, the vehicle can be locked and the detection antennas inside and outside the vehicle can be controlled to stop working.

[0059] If the key outside the vehicle is still searched when the first timing duration is equal to the duration threshold, it means that there is a high probability that the user is talking with other people for a long time outside the vehicle close to the vehicle, and there is a possibility of using the vehicle later. If the vehicle is locked at this time, the subsequent user will need to unlock the car again, causing inconvenience in using the car. In order to avoid inconvenience to the user and save vehicle power consumption at the same time, the second search mode can be entered in this case, that is, determine not to lock the vehicle, and at the same time control the detection antennas inside and outside the vehicle to stop working.

[0060] If the search result shows that no key is found, in order to further avoid missed detection caused by the above-mentioned EMC low-frequency interference, in addition, considering that the key is more likely to appear outside the car after a specified period of time, the third search mode can be entered to continue the key search, that is, the detection antenna inside the car is controlled to stop working, and the detection antenna outside the car is controlled to search for the key once every second preset time, and the timing is started and the second timing duration is obtained. Among them, the second preset time is greater than the first preset time. The higher the search accuracy of the second preset time, the more power consumption is consumed accordingly. Therefore, the second preset time can be set according to actual needs. For example, the second preset time can be 750 milliseconds.

[0061] When the second timing duration is less than the duration threshold and the key outside the vehicle is found, in order to further improve the accuracy of key search and locking, the first search mode can be entered again, that is, the detection antennas inside and outside the vehicle are controlled to search for the key once every first preset time interval, and execute "start timing and obtain the first timing duration; when the first timing duration is less than the duration threshold and the key outside the vehicle is found, determine not to lock the vehicle; when the first timing duration is less than the duration threshold and the key is not found, determine to lock the vehicle and control the detection antennas inside and outside the vehicle to stop working; when the key outside the vehicle is still found when the first timing duration is equal to the duration threshold, determine not to lock the vehicle and control the detection antennas inside and outside the vehicle to stop working".

[0062] When the key is still not found when the second timing duration is equal to the duration threshold, the second search mode is entered, that is, it is determined not to lock the vehicle.

[0063] When it is determined that the vehicle is locked, the IBCM can control the vehicle to be locked. When it is determined that the vehicle is not locked, the IBCM does not control the vehicle to be locked.

[0064] Based on step S110 and step S120, in response to all electric doors of the vehicle being closed being closed, the key located inside or outside the vehicle can be searched within a specified time range, and whether to lock the vehicle can be determined according to the search results. Compared with the current intelligent active locking function that searches for keys after all doors are actually completely closed, the present application determines that all doors are closed in advance during the process of all doors being closed, and searches for keys in advance before the doors are actually closed, so as to avoid the vehicle owner carrying the key away from the vehicle and causing the vehicle to fail to search for the key, thereby improving the key search success rate, avoiding the failure of the vehicle to lock due to the failure of the intelligent active locking function of the vehicle, improving the locking success rate, reducing the risk of vehicle theft, and improving vehicle safety. In addition, by searching for keys within a specified time range, it is possible to avoid the situation where the key cannot be found due to EMC low-frequency interference when it is near devices such as mobile phones / computers / charging piles, because EMC low-frequency interference occurs periodically or occasionally and occurs for a short time, and will not appear continuously, thereby improving the anti-interference of key search, and then improving the key search success rate and locking success rate.

[0065] See also Figure 3 , Figure 3 2 is a flow chart of a locking control method provided by another embodiment of the present application. The locking control method may include steps S210 to S240. In this embodiment, the vehicle involved includes a first type of door and a second type of door. As mentioned above, the first type of door is a door that is not in a closing state, and the second type of door is an electric door that is in a closing state.

[0066] Step S210: In response to the first type of door of the vehicle being closed and the second type of door being closed, searching for a key inside or outside the vehicle within a specified time range, wherein the first type of door is a door that is not in a closing state, and the second type of door is an electric door that is in a closing state.

[0067] In the scenario where the vehicle has first-class doors and second-class doors, it is also necessary to consider the closing status of all doors to determine whether to lock the vehicle. Since the first-class doors are not in the closing state, it is necessary to combine the opening and closing status of the door AJAR switches of the first-class doors to determine whether the first-class doors are open. The IBCM can know the opening and closing status of each door through the door lock motor. For example, the IBCM can collect the door AJAR switch status of all doors. If the door AJAR switches of the first-class doors are all closed, it is determined that the switches of the first-class doors are closed.

[0068] For the parts not described in detail in step S210, please refer to step S110 and will not be repeated here.

[0069] Step S220: Determine whether to lock the vehicle based on the search results.

[0070] For the detailed description of step S220, please refer to step S120, which will not be repeated here.

[0071] Based on step S210 and step S220, for a vehicle equipped with both first-class doors and second-class doors, in response to the first-class doors being closed and the second-class doors being closed, a search can be conducted for keys inside or outside the vehicle within a specified time period, and a determination is made whether to lock the vehicle based on the search results. Compared with the current intelligent active locking function which performs a key search only after all doors are actually completely closed, the present application determines in advance that all doors are closed during the process of the second-class doors being closed, and performs a key search before the doors are actually closed, thereby preventing the owner from carrying the keys away from the vehicle and causing the vehicle to be unable to search for the keys. This can improve the key search success rate, avoid the vehicle's intelligent active locking function failing to fail and causing the vehicle to be locked, improve the locking success rate, reduce the risk of vehicle theft, and improve vehicle safety. In addition, by searching for the key within a specified time range, it is possible to avoid the situation where the key cannot be found due to EMC low-frequency interference when it is near devices such as mobile phones / computers / charging piles. This is because EMC low-frequency interference occurs periodically or occasionally and for a short period of time and will not continue to appear. This can improve the anti-interference ability of the key search, thereby improving the key search success rate and locking success rate.

[0072] In some embodiments, during the execution of steps S110-S120 or steps S210-220, the locking control method may further include the following steps S310 and S320. The vehicle involved in steps S310 and S320 may be equipped with only electric doors in a closing state, or may be equipped with both first-type doors and second-type doors.

[0073] Step S310: When the detection antenna in the vehicle is working, the vehicle-mounted wireless charging module is controlled not to work.

[0074] As mentioned above, in the first search mode, the detection antenna in the car works and searches for the key in the car. Therefore, it is necessary to control the vehicle-mounted wireless charging module not to work, shield the electromagnetic waves sent by the vehicle-mounted wireless charging module, and avoid the electromagnetic waves sent by the wireless charging module from interfering with the key search in the car, thereby improving the success rate of the key search. In other words, in the first search mode, the vehicle-mounted wireless charging module does not work.

[0075] Step S320: When the detection antenna in the vehicle is not working, control the vehicle-mounted wireless charging module to work.

[0076] As mentioned above, in the second search mode and the third search mode, the detection antenna in the car does not work, and the key search in the car is no longer performed. At this time, the wireless charging function can be restored, and the vehicle-mounted wireless charging module can be controlled to resume working, thereby providing the user with the wireless charging function and solving the problem of not being able to use the mobile phone wireless charging function in the car. That is, in the second search mode and the third search mode, the vehicle-mounted wireless charging module works.

[0077] Based on steps S310-320, the key search function can be ensured while solving the problem of passengers in the car not being able to use the wireless charging function of their mobile phones, thereby achieving a two-way guarantee of safety and experience.

[0078] See also Figure 4 , Figure 4 4 is a flowchart of a locking control method provided by another embodiment of the present application. The locking control method may include steps S410 to S420. In this embodiment, all doors of the vehicle involved may be electric doors, or all doors may include electric doors and non-electric doors (such as the first type of doors mentioned above).

[0079] Step S410: In response to some of the vehicle's doors being closed and the remaining doors being closed, searching for keys inside or outside the vehicle within a specified time range, wherein some of the doors include electric doors and / or non-electric doors and the remaining doors are electric doors.

[0080] In some embodiments, in response to receiving a signal that some of the vehicle doors have been closed and receiving a signal that the remaining vehicle doors are closing, the signal that the remaining vehicle doors are closing is set as a closed signal; in response to the closed signal, a key located inside or outside the vehicle is searched within a specified time range.

[0081] Among them, the signal that some of the doors have been closed needs to be received before or at the same time as the signal that the remaining doors are closing. That is, the signal that the remaining doors are closing must be received before the signal that some of the doors have been closed in order to determine in advance that all the doors of the vehicle have been closed, so as to ensure that all the doors will be in a closed state after the remaining doors are closed, and to ensure that the user has the intention to lock the doors. In this case, the key search is performed. On the contrary, if at least one of the doors is not closed when the signal that the remaining doors are closing is received, it cannot be determined that all the doors are closed because it cannot be ensured that all the doors will be in a closed state after the remaining doors are closed. At this time, the user has no intention to lock the doors, and the key search can be omitted. On the one hand, it can avoid the user from mistakenly locking the doors when the user has no intention to lock the doors, and affecting the user experience. On the other hand, it can save computing resources and system power consumption.

[0082] Step S420: Determine whether to lock the vehicle based on the search results.

[0083] In some embodiments, if the search result is that the key is found inside the vehicle, it is determined not to lock the vehicle; and the detection antennas inside and outside the vehicle are controlled to stop working.

[0084] In other embodiments, if the search result is that the key is found outside the vehicle, the timing is started and a first timing duration is obtained; when the first timing duration is less than the duration threshold and the key outside the vehicle is found, it is determined not to lock the vehicle; when the first timing duration is less than the duration threshold and the key is not found, it is determined to lock the vehicle and control the detection antennas inside and outside the vehicle to stop working; when the key outside the vehicle is still found when the first timing duration is equal to the duration threshold, it is determined not to lock the vehicle and control the detection antennas inside and outside the vehicle to stop working.

[0085] In some other embodiments, if the search result is that no key is found, the detection antenna inside the vehicle is controlled to stop working; the detection antenna outside the vehicle is controlled to search for the key once at a second preset time interval, and the timing is started to obtain a second timing duration, and the second preset time duration is greater than the first preset time duration; when the second timing duration is less than a time threshold and the key located outside the vehicle is searched, the detection antennas inside and outside the vehicle are controlled to search for the key once at a first preset time interval, and the steps of starting timing and obtaining the first timing duration are executed; when the key is still not found when the second timing duration is equal to the time threshold, it is determined not to lock the vehicle, and the detection antennas inside and outside the vehicle are controlled to stop working.

[0086] In some embodiments, when the detection antenna in the vehicle is working, the vehicle-mounted wireless charging module is controlled not to work; when the detection antenna in the vehicle is not working, the vehicle-mounted wireless charging module is controlled to work.

[0087] For the parts of step S410 and step S420 in this embodiment that are not described in detail, please refer to the above-mentioned relevant parts and will not be repeated here.

[0088] Based on step S410 and step S420, when some of the vehicle's doors (including electric doors and / or non-electric doors) are closed, it is determined in advance that all doors are closed when it is determined that the remaining doors are closing, and a key search is performed in advance before the remaining doors are actually closed, so as to avoid the vehicle owner carrying the key away from the vehicle and causing the vehicle to be unable to search for the key, thereby improving the key search success rate, avoiding the failure of the vehicle to lock the vehicle due to the failure of the intelligent active locking function of the vehicle, improving the locking success rate, reducing the risk of vehicle theft, and improving vehicle safety. In addition, by searching for the key within a specified time range, it is possible to avoid the situation where the key cannot be found due to EMC low-frequency interference when it is near devices such as mobile phones / computers / charging piles, because EMC low-frequency interference occurs periodically or occasionally and occurs for a short time, and will not appear continuously, thereby improving the anti-interference of the key search, and then improving the key search success rate and the locking success rate.
