Description

Technical Field

[0001] The present invention relates to the field of vehicle control technology, and in particular to a method, device, equipment and storage medium for locking a vehicle with an intelligent key. Background Art

[0002] Leave-and-leave locking (also known as automatic leave-and-leave locking) is a modern car safety feature that uses distance sensing technology to automatically lock the vehicle when the driver leaves the vehicle with the smart key and the vehicle detects that the distance between the key and the vehicle exceeds a preset threshold.

[0003] With the current leave-and-lock function, if the user walks away with the key while the tailgate is closing, the leave-and-lock scenario will not be triggered. If the user walks around the vehicle with the key after all five doors are closed but does not move away from the vehicle, the leave-and-lock and approach-and-unlock scenarios may be triggered, causing the vehicle to be repeatedly unlocked and locked, resulting in a poor user experience.

[0004] The above contents are only used to assist in understanding the technical solution of the present invention and do not constitute an admission that the above contents are prior art. Summary of the invention

[0005] The main purpose of the present invention is to provide a method, device, equipment and storage medium for locking a vehicle with an intelligent key, aiming to solve the problem that a back door cannot be locked when the back door is closed.

[0025] When the state of each side door is that the last door of the four doors enters the closed state, it is determined that the state of the side door and the state of the back door meet the vehicle key detection condition, and the position of the vehicle key is detected.

[0026] In one embodiment, the step of determining whether the back door is in a closed state comprises:

[0027] Acquire a percentage signal of the back door position, determine a sampling period according to the percentage signal of the back door position, and acquire the position signal of the back door based on the sampling period;

[0047] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.

[0048] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.

[0049] It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or an electronic device capable of realizing the above functions, a smart key vehicle locking device (vehicle computer), etc. The following takes the smart key vehicle locking device as an example to illustrate this embodiment and the following embodiments.

[0050] Based on this, the embodiment of the present application provides a method for locking a vehicle with a smart key, referring to Figure 1 , Figure 1 This is a flow chart of the first embodiment of the method for locking a vehicle when a smart key leaves the vehicle.

[0051] In this embodiment, the method for locking the vehicle with the smart key includes steps S10 to S30:

[0052] Step S10, obtaining the door status, which includes the side door status and the back door status;

[0053] It should be noted that the above-mentioned side door status can be any of the side door being in the closed state, open state, closing process and opening process, and the above-mentioned back door status can be any of the back door being in the closed state, open state, closing process and opening process.

[0054] Step S20, when the state of the side door and the state of the back door meet the vehicle key detection condition, detecting the position of the vehicle key;

[0055] It should be noted that the above-mentioned vehicle key detection conditions at least include:

[0056] When the four doors are closed and the tailgate is in the process of closing, the body domain controller drives the antenna to search for the key position;

[0057] When the last of the five doors is closed, the body domain controller drives the antenna to search for the key location;

[0058] When the tailgate is closing and the last of the four doors is closed, the body domain controller drives the antenna to search for the key position.

[0059] It should be understood that the above-mentioned car key position may refer to the area where the car key is located relative to the vehicle, including an unlocking area, a welcome area, a away area, and an invalid key area, such as Figure 2 shown.

[0060] In a feasible implementation, step S20 may include steps A11 to A12:

[0061] Step A11: when the side door is in the closed state, determining whether the back door is in the closed state;

[0062] Step A12: When the back door is in the process of closing or in the closed state, determine whether the side door state and the back door state meet the vehicle key detection condition, and detect the vehicle key position.

[0063] In a specific implementation, when the four doors are closed and the tailgate is in the process of closing, the body domain controller drives the antenna to search for the key position.

[0064] In another feasible implementation, step S30 may include steps A21 to A22:

[0065] Step A21: When the back door is in the closing process, detecting the status of each side door;

[0066] Step A22: When the state of each side door is in the last door of the four doors entering the closed state, determine whether the state of the side door and the state of the back door meet the vehicle key detection condition, and detect the position of the vehicle key.

[0067] In a specific implementation, when the tailgate is closing and the last of the four doors is closed, the body domain controller drives the antenna to search for the key position.

[0068] It should be understood that when the last of the five doors is closed, the body domain controller will also drive the antenna to search for the key position.

[0069] Furthermore, after the step of obtaining the position of the vehicle key, steps A31 to A32 are also included:

[0070] Step A31: When it is detected that the vehicle key position moves from the unlocking area to the welcome area, the vehicle is locked through a sound prompt;

[0071] In the specific implementation, when the car key moves from the unlocking area to the welcome area, the system will remind the driver through sound that the vehicle is about to be locked, which can ensure that the driver knows that the vehicle is safely locked when leaving the vehicle. For example, some models can activate the function of locking the car horn through the vehicle settings.

[0072] Step A32: When it is detected that the vehicle key position moves from the welcome area to the away area, the vehicle status information is transmitted to the user end, and the vehicle status information includes door closing information, window closing information and parking position information.

[0073] In the specific implementation, when the car key moves from the welcome area to the away area, the vehicle will transmit status information to the user. This status information may include door closing information, window closing information, and parking position information. Such a feedback mechanism allows the driver to still confirm the safety status of the vehicle after leaving the vehicle. For example, through the Internet of Vehicles technology, the vehicle can be connected to the cloud server in real time through the 4G / 5G network to realize the transmission and remote control of vehicle information.

[0074] Step S30, when it is detected that the vehicle key is in an invalid key area, the vehicle is locked.

[0075] It should be noted that the invalid key area means that when the body domain controller drives the antenna to search for the key position, the key position is not found for five consecutive times.

[0076] In a feasible implementation manner, step S30 may include steps A41 to A42:

[0077] Step A41: When it is detected that the position of the car key moves from any one of the unlocking area, the welcome area, and the invalid area to the preset area, the detection number is recorded, and the preset area is the area where the position of the car key cannot be detected;

[0078] In a specific implementation, the position change of the key from the unlocking area or the welcome area or the invalid area to the invalid key area is recorded, and the number of detections is also recorded.

[0079] Step A42: When the number of detections reaches a preset number, it is determined that the vehicle key is in an invalid key area, and the vehicle is locked.

[0080] If the key cannot be found for five consecutive times, the key position condition for leaving the vehicle and locking it is met, a vehicle locking command is issued, and the body domain controller drives the entire vehicle to lock.

[0081] The present embodiment provides a method for locking the vehicle when leaving the vehicle with a smart key, which obtains the door status, including the side door closed status and the back door status; when the side door status and the back door status meet the vehicle key detection conditions, the vehicle key position is detected; when it is detected that the vehicle key position is in an invalid key area, the vehicle is controlled to be locked, which reduces the probability of accidental locking and improves the success rate of locking the vehicle when leaving the vehicle, so that the vehicle's locking function when leaving the vehicle has a better experience and safety.

[0082] Based on the first embodiment of the present application, in the second embodiment of the present application, the same or similar contents as those in the above-mentioned embodiment 1 can be referred to the above introduction, and will not be repeated in the following. Figure 3 , step S20 includes steps S201 to S203:

[0083] Step S201, obtaining a percentage signal of the back door position, determining a sampling period according to the percentage signal of the back door position, and obtaining a position signal of the back door based on the sampling period;

[0084] In the specific implementation, first obtain the percentage signal (0-100) of the back door position, and identify the change trend of the back door position signal in real time; detect the door status, lock status, power gear, vehicle settings, key position radio frequency signals, etc. in real time.

[0085] It should be noted that when detecting the movement status of the back door, assuming that the back door position signal sending period is 100ms and the software running period is 10ms, the software cannot simply identify the position change through the continuous change trend. At this time, the sampling period needs to be set to be greater than 100ms, such as 150ms, to detect the signal change more intuitively.

[0086] Step S202, when it is detected that the position signal of the back door is decreasing within a continuous preset sampling period, determining that the back door is in the closing process;

[0087] It should be noted that one sampling period may be 150 ms, and the preset sub-sampling period may be three sampling periods, that is, three consecutive sampling points.

[0088] In the specific implementation, the sampling period is set to 150ms, and a position signal of the back door is memorized. If the position signal decreases successively at three consecutive sampling points, it is considered that the back door is in the process of closing.

[0089] Furthermore, if the position signals are increasing in sequence at three consecutive sampling points, it is considered that the back door is being opened.

[0090] Step S203: when it is detected that the position signal of the back door remains unchanged within a continuous preset sub-sampling period, it is determined that the back door is in a closed state.

[0091] In a specific implementation, if the position signal remains unchanged for five consecutive sampling points, it is considered that the tailgate has stopped moving.

[0092] It should be noted that at this time, it is also necessary to determine the change in the signal before the position signal remains unchanged. If the signal increases, the back door is determined to be in the open state. If the signal decreases, the back door is determined to be in the closed state.

[0093] This embodiment provides a method for locking the vehicle when leaving the vehicle with a smart key, and after detecting the movement state of the back door, it is used as a judgment condition for locking the vehicle when leaving the vehicle. By processing three sampling points of 150ms, misidentification of the movement state of the back door can be effectively prevented.

[0094] Based on the first and second embodiments of the present application, in the third embodiment of the present application, the same or similar contents as those in the above embodiments can be referred to the above introduction, and will not be described in detail later. Figure 4 , step S30 includes steps S301 to S303:

[0095] Step S301, obtaining a first preset timing duration;

[0096] It should be noted that due to the complex and changeable user usage scenarios, the vehicle can only be locked after the key position and five-door status are all met. Therefore, two timers, namely timer a and timer b, are added while waiting for the locking conditions to be met.

[0097] The first preset timing duration can be calibrated, such as five minutes.

[0098] Step S302, when the position of the car key is continuously detected within a first preset timing period, detecting whether the position of the car key is in an invalid key area;

[0099] It should be noted that when the conditions for entering and leaving the vehicle are met, the timer a (the time can be calibrated) is entered to continuously detect the key position within the specified time. If the key position meets the requirements and the five doors are closed, the vehicle is controlled to be locked;

[0100] Step S303, when it is detected that the vehicle key position is not in the invalid key area, exit the vehicle key position detection process.

[0101] It should be noted that if timer a times out, that is, if the vehicle key is detected to be in an invalid key area within the first preset timing period, the key position search process will be exited, and the vehicle can only be re-entered after meeting the conditions for leaving the vehicle and locking the vehicle.

[0102] In a specific implementation, if the specific location of the car key can still be detected after five minutes, the search process for the car key is canceled.

[0103] In a feasible implementation manner, step S301 may further include steps A51 to A52:

[0104] Step A51: when it is detected that the vehicle key is in an invalid key area, obtaining a second preset timing duration;

[0105] It should be noted that when the conditions for entering and locking the vehicle are met, the key position meets the locking conditions in timer a, but if the five doors are not completely closed at this time, timer b is entered (waiting for the five doors to be closed).

[0106] It should be noted that the second preset timing duration can be calibrated, such as five minutes or ten minutes.

[0107] Step A52: When it is continuously detected that all the doors are in the closed state within the second preset timing period, the vehicle is locked.

[0108] It should be noted that, within the timer b, when the five doors are closed, the vehicle is controlled to be locked; if the timer b times out and the five doors are not closed, the vehicle will not be locked.

[0109] In a specific implementation, if the specific location of the car key can still be detected after 10 minutes, the search process for the car key is canceled.

[0110] The present embodiment provides a method for locking the vehicle when the smart key is away from the vehicle. The system ensures that the vehicle key is not in the vehicle and all the doors are closed before performing the locking operation, thereby preventing the vehicle from being locked in an unsafe state. At the same time, the user does not have to wait for all the doors to be completely closed when leaving the vehicle. The system will automatically check and lock the vehicle in the background, thereby reducing the user's waiting time. Furthermore, if the user realizes that the door is not closed after leaving the vehicle, the system will not lock the vehicle immediately, giving the user a chance to return to the vehicle to make corrections. By setting a reasonable timer duration, the power consumed by the vehicle due to continuous detection of the key position can be reduced.

[0111] It should be noted that the above examples are only used to understand the present application and do not constitute a limitation on the method of locking the vehicle when the smart key leaves the vehicle. More simple changes based on this technical concept are all within the scope of protection of the present application.

[0120] When the position of the vehicle key is continuously detected within a first preset timing period, detecting whether the position of the vehicle key is in an invalid key area;

[0121] When it is detected that the vehicle key position is not in the invalid key area, the vehicle key position detection process is exited.

[0122] In one embodiment, the vehicle locking module 30 is further used to obtain a second preset timing duration when it is detected that the vehicle key is in an invalid key area;

[0123] When it is continuously detected that all the doors are in the closed state within the second preset timing time, the vehicle is controlled to be locked.

[0124] In one embodiment, the vehicle key position acquisition module 20 is further used to determine whether the back door is in a closed state when the side door is in a closed state;

[0128] When it is detected that the position signal of the back door is decreasing within consecutive preset sampling periods, determining that the back door is in the closing process;
