[0042] In order to facilitate the understanding of the application, the application will be described more fully below with reference to the related drawings. The drawings show several embodiments of the application. However, the application can be realized in many different forms, and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the application more thorough and comprehensive.

[0043] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be intervening elements. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements can be present. As used herein the terms "vertical", "horizontal", "left", "right", and the like are merely for purposes of illustration.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0045] When the owner inadvertently triggers the smart key or passes by the car, the car intelligent system detects the key close or unlock instruction, and will mistakenly think that the owner is about to enter the car. In order to facilitate the owner to directly open the door, the car intelligent system will automatically unlock the door in advance. If the owner is just passing by the car and does not intend to enter the car, anyone can directly open the door at this time, which is easy to cause loss of property in the car. Therefore, the unlocking condition of the car using the smart key in the prior art still has certain deficiencies, which will increase the risk of theft of property in the car.

[0046] The present application aims to limit the unlocking condition of the smart key, which can avoid the unlocking of the car due to the mistaken triggering of the unlocking instruction of the smart key and the direct unlocking of the car due to the sensing when the user carrying the smart key passes by the car, so as to establish a return protection mechanism for unlocking the car by the smart key, thereby solving the technical problem that the car is unlocked when the user inadvertently enters the car in the prior art, which is easy to cause the theft of property in the car. For specific technical solutions, please refer to the several preferred embodiments listed in the present application.

[0047] Embodiment one

[0048] Please refer to Figure 1 The first embodiment of the present application provides an automobile automatic return protection control method for returning protection when a user mistakenly triggers an unlocking instruction by a smart key and the car is unlocked due to the proximity of the car. The smart key includes but is not limited to a digital key such as Bluetooth, 4G / 5G, NFC, smart wear, and even a smart remote key. The above various forms of keys are collectively referred to as smart keys in this embodiment, which can control the car by triggering instructions, including unlocking instructions, locking instructions, etc., and can also achieve unlocking of the car by sensing. In this embodiment, the method includes steps S10-S40:

[0049] Step S10, receiving the unlocking instruction and the position information of the smart key when the car is in the security state, determining the distance value between the smart key and the car according to the position information;

[0050] It should be noted that the security state of the car refers to the state that the doors and the tailgate of the car are closed, and the doors and the tailgate of the car will always remain closed when no unlocking instruction or unlocking signal is received, so as to be regarded as the security state of the car.

[0051] Specifically, when the car is in the security state, the key system in the car is always in a working state, so that the unlocking instruction issued by the smart key and the position information of the current position of the smart key can be received in the first time, so as to determine the distance of the smart key relative to the car and the distance value between the smart key and the car.

[0052] Among them, the distance value between the smart key and the car is determined based on the installation position of the key system in the car as the center, that is, the distance value is not the distance value of the smart key from the outermost panel of the car.

[0053] Step S20, judging whether the distance value between the smart key and the car is within the preset diameter of the security range;

[0054] First of all, it should be noted that the remote control distance of the remote control key is usually more than 60 meters, and the remote control distance of the smart key is usually infinite as long as it can be connected, that is, the remote control distance of such smart key is relatively far.

[0055] Suppose the user carries the smart key 200 meters away from the car and accidentally triggers the unlocking instruction, but the user does not intend to enter the car, at this time anyone can open the door, so there is a risk of theft of property in the car.

[0056] But in this embodiment, the distance value between the smart key and the car will be determined according to the position information of the smart key, and whether the distance value is within the preset diameter of the security range. For example, but not limited to, the radius of the security range is 5 meters, that is, the security range is a circle with the key system in the car as the center and the radius of 5 meters.

[0057] As Figure 2 shown, when the user carries the smart key outside the security range and accidentally triggers the unlocking instruction, for example, the smart key is placed in the pocket and is squeezed to trigger, at this time the car will enter the preset security state from the security state, since the smart key does not exist in the security range, even if the key system of the car receives the unlocking instruction, it will not directly unlock the door, at this time the person in the security range cannot open the door, which can effectively avoid the theft of property.

[0058] In the embodiment, if the distance value between the smart key and the car is within the preset diameter of the security range, the method shown in the embodiment enters step S30.

[0059] Step S30, the door of the car is controlled to be unlocked to enter the preset security state, and a preset time period countdown is entered;

[0060] It should be noted that when the smart key is present in the security range, it means that the user is close to the car, at this time the door of the car is controlled to be unlocked and enters the preset security state, that is, when the user does not pull the door to enter the car, the car is always in the preset security state.

[0061] As shown in the Figure 3 When the car enters the preset security state, a preset period countdown is entered, for example, 30s, before the countdown ends, the position information of the smart key is obtained in real time, and it is judged whether it is in the security range, if the smart key is in the security range and the door is opened, it means that the unlocking operation is made by the user, and the countdown is cancelled.

[0062] The period of the countdown can also be set as needed, the shorter the timing time, the shorter the time difference between the unlocking in the preset security state and the locking in the security state, and the car is relatively safer, but it is easy to lead to too harsh unlocking conditions, which is not conducive to user use. Therefore, the timing period of the countdown should not be too long or too short, and moderate is enough, which ensures that the user is still within the perceptible range when the timing ends.

[0063] However, in the daily use process, there is also a situation that the user carries the smart key through the car but does not enter the car by mistake, and the method shown in the embodiment enters step S40.

[0064] Step S40, if the distance value between the smart key and the car exceeds the security range within the timing period, the door of the car is controlled to be locked to re-enter the security state.

[0065] For example, within the 30s timing period countdown, the user carries the smart key through the car, if it takes 4s to pass through the security range of the car along the length direction of the car, within the 4s, the car will switch from the security state to the non-security state, and the car is in the waiting state.

[0066] As shown in the Figure 4As shown, within the 4 seconds of passing through the defense range, 1 second corresponds to a node position of the smart key, namely node position P1, node position P2, node position P3 and node position P4 within the defense range, and the distances between node position P1, node position P2, node position P3 and node position P4 and the key system in the car are d1, d2, d3 and d4 respectively. If the distances d1, d2, d3 and d4 between the smart key and the key system first get closer and then farther away, it is determined that the user carrying the smart key is just passing by the car and does not stay next to the car, and has no intention of entering the car. Therefore, when the user carrying the smart key gradually moves away and the countdown ends, the car is locked to re-enter the defense state.

[0067] Of course, the above situation does not rule out the possibility that the user temporarily changes his intention to enter the car. During the timing period, the user carrying the smart key can directly unlock the car by pulling the door, key sensing or issuing an unlocking command in the preset protection state, thereby improving the user experience while ensuring the safety of the car.

[0068] On the contrary, if Figure 5 As shown, if the distances d1, d2, d3, and d4 between the smart key and the key system gradually decrease, it is determined that the user is carrying the smart key close to the car and is next to the car, with the intention of entering the car. When the user unlocks the car by pulling the car door, key sensing, or issuing an unlock command, the car will be unlocked directly and the countdown ends.

[0069] In summary, compared with the prior art, the automobile automatic return defense control method shown in this embodiment has the following beneficial effects:

[0070] When the car is in a locked and fortified state, it receives the unlocking instruction and location information of the smart key, determines the distance value between the smart key and the car, and if the distance value is within the fortified range of the preset instruction, controls the door of the car to unlock to enter the preset fortified state, and enters the countdown of the preset time period. During the timing period, if the distance value between the smart key and the car exceeds the fortified range from the fortified range, it means that the user is just passing by the vehicle. Before the countdown ends, if the user does not unlock the car by pulling the door, key sensing or issuing an unlocking instruction, the vehicle will be locked and re-entered the fortified state after the countdown ends. This ensures that the vehicle will not be unlocked when the user passes by the vehicle with the smart key, and prevents the property in the vehicle from being stolen by others who are near the vehicle at the time. This solves the technical problem in the prior art that the smart key is unlocked when it approaches the car, which increases the risk of theft of property in the car.

[0071] Example 2

[0072] A second embodiment of the present invention provides a method for controlling an automatic vehicle return to safety. The method:

[0073] In the embodiment, the step of controlling the vehicle door to lock to re-enter the security state if the distance value between the smart key and the vehicle exceeds the security range during the timing period specifically includes:

[0074] Obtaining the distance value between the smart key and the vehicle at each time node during the timing period to generate a time-distance relationship;

[0075] Determining whether the distance value between the smart key and the vehicle at any time node exceeds the security range;

[0076] If yes, controlling the vehicle door to lock to re-enter the security state;

[0077] In the step of determining whether the distance value between the smart key and the vehicle at any time node exceeds the security range, the method further includes:

[0078] Determining a plurality of key time nodes during the timing period according to the time-distance relationship;

[0079] Obtaining a plurality of key distance values between the smart key and the vehicle at a plurality of key time nodes;

[0080] Generating a moving track of the smart key according to a plurality of key time nodes and a plurality of key distance values corresponding to the key time nodes, to determine the real intention of the user according to the moving track of the smart key.

[0081] In the step of generating a moving track of the smart key according to a plurality of key time nodes and a plurality of key distance values corresponding to the key time nodes, to determine the real intention of the user according to the moving track of the smart key, specifically includes:

[0082] Determining a moving direction of the smart key between a current key time node and a next key time node according to the key distance value at the key time node;

[0083] Determining a relative position of the smart key and the vehicle at the key time node according to the moving direction of the smart key, to determine a plurality of node positions of the smart key at a plurality of key time nodes;

[0084] Concatenating coordinate points of a plurality of node positions to generate a moving track of the smart key, to determine the real intention of the user according to the moving track of the smart key.

[0085] In the embodiment, the user can directly unlock the vehicle by carrying the smart key in the preset security state, and a first prompt that the smart key is within the security range is given in the preset security state.

[0086] The first prompt is an audible and / or visual prompt of the car and / or an information prompt of the car intelligent program, for example, a single beep of the car horn and / or a flicker of the clearance lamp, so that the user can be prompted by sound and light that the current vehicle is in the preset security state.

[0087] In some other embodiments, the first prompt is issued by the car intelligent program, for example, the car intelligent program issues a warning prompt to prompt the user that the current vehicle is in the preset security state.

[0088] In the present embodiment, when the smart key enters the preset security range to make the car enter the preset security state, and then moves away from the preset security range to make the car re-enter the security state, a second prompt is issued that the smart key has passed through the preset security range.

[0089] Similarly, the second prompt is an information prompt of the car intelligent program.

[0090] In summary, compared with the prior art, the car automatic security control method shown in the present embodiment has at least the following beneficial effects:

[0091] When the car is in the locked security state, the unlocking instruction and position information of the smart key are received, the distance value between the smart key and the car is determined, if the distance value is within the preset instruction security range, the car door is controlled to be unlocked to enter the preset security state, and a preset time period countdown is entered, if the distance value between the smart key and the car exceeds the security range during the countdown period, it means that the user is just passing by the vehicle, before the countdown ends, if the user does not unlock the car by pulling the door, key induction or issuing an unlocking instruction, after the countdown ends, the vehicle will be locked and re-enter the security state, so that when the user carries the smart key and passes by the vehicle, the vehicle will not be unlocked, and the risk of theft of the vehicle's property is avoided, solving the technical problem that in the prior art, the smart key is close to the car and is unlocked, increasing the risk of theft of the vehicle's property.

[0092] Embodiment three

[0093] Please refer to Figure 6 The third embodiment of the present application provides a car automatic security control system for preventing the user from triggering the unlocking instruction by mistake and preventing the car from being unlocked due to the user's proximity to the car using a smart key, which includes but is not limited to a digital key such as Bluetooth, 4G / 5G, NFC, smart wear, and even a smart remote key. The above-mentioned keys are collectively referred to as smart keys in the present embodiment, which can control the car by triggering instructions, including unlocking instructions, locking instructions, etc., and can also unlock the car by induction.

[0094] In the embodiment, the system comprises a distance calculation module 10, a condition judgment module 20, a timing starting module 30 and a security execution module 40.

[0095] The distance calculation module 10 is configured to receive an unlocking instruction and position information of the smart key when the car is in a security state, and determine a distance value between the smart key and the car according to the position information.

[0096] It should be noted that the security state of the car refers to the state that the doors and the tailgate of the car are closed, and the doors and the tailgate of the car will always remain closed when no unlocking instruction or unlocking signal is received, so as to be regarded as the security state of the car.

[0097] Specifically, when the car is in the security state, the key system in the car is always in a working state, so as to receive the unlocking instruction and the position information of the current position of the smart key in the first time, and determine the distance between the smart key and the car.

[0098] The distance value between the smart key and the car is determined based on the installation position of the key system in the car as the center, that is, the distance value is not the distance between the smart key and the outermost panel of the car.

[0099] The condition judgment module 20 is configured to judge whether the distance value between the smart key and the car is within a preset diameter security range.

[0100] First of all, it should be noted that the remote control distance of the remote key is usually more than 60 meters, and the remote control distance of the smart key is usually infinite as long as it can be connected, that is, the remote control distance of such smart key is relatively far.

[0101] Suppose that the user carries the smart key 200 meters away from the car and accidentally triggers the unlocking instruction, but the user does not intend to enter the car, at this time, anyone can open the door, so that there is a risk of theft of the property in the car.

[0102] However, in the embodiment, the distance value between the smart key and the car is determined according to the position information of the smart key, and whether the distance value is within a preset diameter security range is judged. For example, but not limited to, the radius of the security range is 5 meters, that is, the security range is a circle with the key system in the car as the center and the radius of 5 meters.

[0103] For example, Figure 2As shown, when the user carries the smart key outside the security range and mistakenly triggers the unlocking instruction, for example, the smart key is placed in the pocket and is squeezed to be mistakenly touched, at this time, the car will enter the preset security state from the security state, since the smart key does not exist in the security range, even if the car key system receives the unlocking instruction, the car door will not be directly unlocked, at this time, the person in the security range cannot open the car door, which can effectively prevent the property from being stolen.

[0104] In the embodiment, if the distance value between the smart key and the car is within the preset diameter security range, the system shown in the embodiment enters step S30.

[0105] The timing starting module 30 is configured to control the car door to be unlocked to enter the preset security state and enter a preset time period countdown when the condition judgment module judges that the distance value between the smart key and the car is within the security range.

[0106] It should be noted that when the smart key exists in the security range, it means that the user is close to the car, at this time, the car door will be controlled to be unlocked and enter the preset security state, that is, when the user does not pull the car door to enter the car, the car is always in the preset security state.

[0107] As shown in the Figure 3 When the car enters the preset security state, a preset period countdown, for example, 30s, will be entered, before the countdown ends, the position information of the smart key will be obtained at all times to judge whether it is within the security range, if the smart key is within the security range and the door is opened, it means that the unlocking operation is made by the user, and the countdown is cancelled.

[0108] The period of the countdown can also be set as needed, the shorter the timing time, the shorter the time difference between the unlocking in the preset security state and the locking in the security state, the car is relatively safer, but it is easy to lead to too harsh unlocking conditions, which is not conducive to the use of the user, therefore, the timing period of the countdown should not be too long or too short, and it is appropriate to be moderate, which can ensure that the user is still within the perceptible range when the timing ends.

[0109] The security execution module is configured to control the car door to be locked to re-enter the security state if the distance value between the smart key and the car exceeds the security range within the timing period.

[0110] For example, within the 30s countdown of the timing period, the user carries the smart key through the car, if the security range of the car is used for 4s along the length direction of the car, within the 4s, the car will switch from the security state to the non-security state, and the car is in the waiting state.

[0111] As shown in the Figure 4As shown, within the 4 seconds of passing through the defense range, 1 second corresponds to a node position of the smart key, namely node position P1, node position P2, node position P3 and node position P4 within the defense range, and the distances between node position P1, node position P2, node position P3 and node position P4 and the key system in the car are d1, d2, d3 and d4 respectively. If the distances d1, d2, d3 and d4 between the smart key and the key system first get closer and then farther away, it is determined that the user carrying the smart key is just passing by the car and does not stay next to the car, and has no intention of entering the car. Therefore, when the user carrying the smart key gradually moves away and the countdown ends, the car is locked to re-enter the defense state.

[0112] Of course, the above situation does not rule out the possibility that the user temporarily changes his intention to enter the car. During the timing period, the user carrying the smart key can directly unlock the car by pulling the door, key sensing or issuing an unlocking command in the preset protection state, thereby improving the user experience while ensuring the safety of the car.

[0113] On the contrary, if Figure 5 As shown, if the distances d1, d2, d3, and d4 between the smart key and the key system gradually decrease, it is determined that the user is carrying the smart key close to the car and is next to the car, with the intention of entering the car. When the user unlocks the car by pulling the car door, key sensing, or issuing an unlock command, the car will be unlocked directly and the countdown ends.

[0114] In summary, compared with the prior art, the automobile automatic return protection control system shown in this embodiment has the following beneficial effects:

[0115] When the car is in a locked and fortified state, it receives the unlocking instruction and location information of the smart key, determines the distance value between the smart key and the car, and if the distance value is within the fortified range of the preset instruction, controls the door of the car to unlock to enter the preset fortified state, and enters the countdown of the preset time period. During the timing period, if the distance value between the smart key and the car exceeds the fortified range from the fortified range, it means that the user is just passing by the vehicle. Before the countdown ends, if the user does not unlock the car by pulling the door, key sensing or issuing an unlocking instruction, the vehicle will be locked and re-entered the fortified state after the countdown ends. This ensures that the vehicle will not be unlocked when the user passes by the vehicle with the smart key, and prevents the property in the vehicle from being stolen by others who are near the vehicle at the time. This solves the technical problem in the prior art that the smart key is unlocked when it approaches the car, which increases the risk of theft of property in the car.
