[0002] Digital keys are often also called Bluetooth keys or virtual keys. With the promotion of smart cars, this new key technology will become a standard feature of the next generation of cars.

[0041] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0042] In one embodiment, Figure 1 As shown, a vehicle control method is provided. This embodiment uses the method applied to a digital key controller (Ignition Key Module, IKM) in a vehicle as an example for illustration. It can be understood that the method can also be applied to a vehicle terminal, and can also be applied to a system including a vehicle terminal and an IKM controller, and is implemented through the interaction between the vehicle terminal and the IKM controller. In this embodiment, the method includes the following steps:

[0043] S110, obtaining the position change of the digital key of the target vehicle in the current time period.

[0044] Among them, the target vehicle can be a vehicle equipped with a digital key. For example, the target vehicle can be an electric vehicle, a hybrid vehicle, or a gasoline vehicle. This application does not impose any limitations on this.

[0045] The digital key can be a mobile terminal, such as a mobile phone, that has an application logged in to the target vehicle and has established a binding relationship with the target vehicle. The digital key can be connected to the IKM controller via Bluetooth within the Bluetooth sensing range of the IKM controller, thereby exchanging data with the IKM controller to temporarily open the door of the target vehicle.

[0046] The current time period may include the current moment and a preset historical time period before the current moment; the length of the preset historical time period may be determined based on manual experience. For example, the preset historical time period may be 10 seconds or 5 seconds, and this application does not impose any limitation on this.

[0047] In an optional implementation, when it is determined that the digital key has entered the Bluetooth sensing range of the IKM controller, the location information of the digital key at different times is obtained based on Bluetooth communication. Exemplarily, the IKM controller can locate the digital key in real time or at a fixed time based on Bluetooth communication, and use the location results of the digital key at different times as the location information of the digital key at the corresponding time. Furthermore, the change of the location information of the digital key at different times in the current time period is used as the location change of the digital key in the current time period.

[0048] Optionally, the IKM controller may also use the position information of the digital key at the start time, the midpoint time, and the end time of the current time period as the position change of the digital key in the current time period. For example, the position change of the digital key in the current time period may be such as "XX hours:XX minutes:XX seconds (starting time), coordinates (a, b), XX hours:XX minutes:XX seconds (midpoint time), coordinates (c, d), XX hours:XX minutes:XX seconds (end time), coordinates (e, f)".

[0049] S120, determining a target position of the digital key according to the position change.

[0050] Among them, the target position can be used as the exact position of the digital key at the current moment.

[0051] It should be noted that since the Bluetooth field strength itself is easily interfered, the location information of the digital key determined based on Bluetooth communication may not be accurate. In this case, after determining the location information of the digital key at the current moment based on Bluetooth communication, the present application will determine the accuracy of the location information according to the location change to determine the target location of the digital key.

[0052] In an optional embodiment, the position change of the digital key in the current time period can be input into a pre-trained target position determination model to obtain the target position of the digital key. It should be noted that the target position determination model can be constructed based on a common neural network, which will not be described in detail here. Furthermore, in the process of training the target position determination model, the position change of the reference digital key in the sample time period can be input into the target position determination model to obtain the predicted position of the reference digital key. According to the position label and predicted position of the reference digital key, the target position determination model is trained to improve the model accuracy of the target position determination model.

[0053] S130, controlling the locks or lights of the target vehicle according to the target position.

[0054] In an optional implementation, the locks or lights of the target vehicle are controlled according to the target position and a preset vehicle control strategy. For example, reference control modes corresponding to different reference positions are predetermined, and the reference control modes corresponding to the target position are used as target control modes for the target vehicle, and then the locks or lights of the target vehicle are controlled based on the target control modes.

[0055] Optionally, the method of controlling the locks of the target vehicle may include controlling the locks to be opened and controlling the locks to be closed; the method of controlling the lights of the target vehicle may include controlling the lights to be turned on and controlling the lights to be turned off.

[0056] In the above vehicle control method, the position change of the key of the target vehicle in the current time period is obtained, and the target position of the digital key is determined according to the position change, and then the lock or light of the target vehicle is controlled according to the target position. In this process, before the lock or light of the target vehicle is controlled, the exact position of the digital key is determined according to the position change of the digital key in the current time period, so that the control of the target vehicle is more accurate.

[0057] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the process of determining the target position of the digital key according to the position change situation is refined.

[0058] See Figure 2The target position determination steps shown include:

[0059] S210, determining the position change trend of the digital key in the current time period according to the position change situation.

[0060] Among them, the position change trend can represent the change in the direction of travel of the digital key in the current time period.

[0061] In an optional implementation, the position change can be used to characterize the relative distance change between the digital key and the target vehicle. Accordingly, if the relative distance changes with time, it is determined that the position change trend of the digital key in the current time period is close to the vehicle; if the relative distance changes with time, it is determined that the position change trend of the digital key in the current time period is far away from the vehicle.

[0062] It should be noted that the position change trend of the digital key in the current time period is either close to the vehicle or far away from the vehicle, and the position change trend is normal. However, if the relative distance changes with time first farther and then closer, or first closer and then farther, it is determined that the position change trend of the digital key in the current time period is abnormal.

[0063] In an optional implementation, the current time period includes a first current time period at the current moment, a first historical time period adjacent to the first current time period, and a second historical time period adjacent to the first historical time period. In this case, the first position change trend can be determined based on the first historical position of the digital key in the first historical time period and the second historical position in the second historical time period; the second position change trend can be determined based on the first historical position and the current position of the digital key in the first current time period.

[0064] Among them, the position change trend includes a first position change trend and a second position change trend; the length of the first current period, the first historical period, and the second historical period can be determined based on manual experience or through a large number of experiments. This application does not impose any limitations on this. By way of example, the length of the first current period, the first historical period, and the second historical period can be the same or different.

[0065] Exemplarily, the change trend from the second historical position to the first historical position is taken as the first position change trend. For example, if the first distance between the second historical position and the IKM controller is less than the second distance between the first historical position and the IKM controller, the first position change trend of the digital key is away from the vehicle. The change trend from the first historical position to the current position is taken as the second position change trend. For example, if the second distance between the first historical position and the IKM controller is less than the third distance between the current position and the IKM controller, the second position change trend of the digital key is away from the vehicle.

[0066] For another example, if the first distance between the second historical position and the IKM controller is greater than the second distance between the first historical position and the IKM controller, the first position change trend of the digital key is close to the vehicle. The change trend from the first historical position to the current position is taken as the second position change trend. For example, if the second distance between the first historical position and the IKM controller is greater than the third distance between the current position and the IKM controller, the second position change trend of the digital key is close to the vehicle.

[0067] It should be noted that since the first current period, the first historical period and the second historical period all include multiple moments, in order to ensure the uniqueness of the current position, the first historical position and the second historical position, this embodiment can use the location information of the digital key at any moment in the first current period as the current position. Use the location information of the digital key at any moment in the first historical period as the first historical position. Use the location information of the digital key at any moment in the second historical period as the second historical position. Among them, any moment in each period can be selected based on manual experience, and illustratively, it can be the starting moment, the ending moment, or the midpoint moment, and this application does not impose any limitation on this.

[0068] S220, determining a target position of the digital key according to a change in the position change trend.

[0069] In an optional implementation, the target position of the digital key can be determined based on the position change trend between adjacent moments in the current time period. For example, if the position change trend between the current moment and the moment before the current moment is different from the position change trend between the moment before the current moment and the moments before that, then the moment before the current moment is the moment before the position change trend changes, and therefore, the position of the digital key at the moment before the current moment can be used as the target position of the digital key.

[0070] In an optional implementation, the current time period includes a first current time period at the current moment, a first historical time period adjacent to the first current time period, and a second historical time period adjacent to the first historical time period. In this case, if the position change trend in the current time period remains unchanged, the current position of the digital key is used as the target position of the digital key; if the position change trend in the current time period changes, the position of the digital key before the position change trend changes is used as the target position of the digital key.

[0071] For example, if the first position change trend and the second position change trend are both approaching the vehicle or moving away from the vehicle, the current position of the digital key is used as the target position of the digital key. If the first position change trend and the second position change trend change, for example, the first position change trend is approaching the vehicle and the second position change trend is moving away from the vehicle, the position of the digital key before the position change trend changes, that is, the first historical position in the first historical period, is used as the target position of the digital key.

[0072] In the above embodiment, the process of determining the target position of the digital key according to the position change situation is refined. Specifically, according to the position change situation, the position change trend of the digital key in the current time period is determined. When the position change trend changes, it is considered that the Bluetooth field strength is interfered, that is, the position recognition of the digital key is determined to be abnormal. This avoids abnormal control of the vehicle when the Bluetooth field strength is interfered.

[0073] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, a specific method for obtaining the position change of the digital key of the target vehicle in the current time period is described in detail.

[0074] See also Figure 3 The steps for obtaining the position change of the digital key shown include:

[0075] S310: Determine the current position of the digital key within the first current time period according to the current time and the preset sliding window length.

[0076] The preset sliding window length can be determined based on manual experience, or can be determined according to specific application requirements and data processing speed, or can be determined through a large number of experiments, and this application does not impose any limitation on this. It can be understood that the first current period includes the current moment and each moment within the preset sliding window length before the current moment.

[0077] Optionally, in this embodiment, the current position of the digital key in the first current period can be determined based on the current position of the digital key at the current moment and the historical position of the digital key at each moment in the preset sliding window length before the current moment. Exemplarily, the position of the digital key at any moment in the first current period can be used as the current position of the digital key in the first current period. For example, the current position can be used as the current position of the digital key in the first current period, or the historical position of the digital key at the start moment of the first current period can be used as the current position of the digital key in the first current period.

[0078] S320: Determine a first historical position of the digital key within a first historical period according to a start time of the first current period and a preset sliding window length.

[0079] It can be understood that the first historical period includes the start time of the first current period and each time within a preset sliding window length before the start time of the first current period.

[0080] Optionally, in this embodiment, the first historical position of the digital key in the first historical period can be determined based on the historical position of the digital key in the first historical period and the historical position of the digital key in a preset sliding window length before the start time of the first current period. Exemplarily, the position of the digital key at any time in the first historical period can be used as the first historical position of the digital key in the first historical period. For example, the historical position at the start time of the first current period or the historical position of the digital key at the start time of the first historical period can be used as the first historical position of the digital key in the first historical period.

[0081] S330: Determine a second historical position of the digital key within a second historical period according to the start time of the first historical period and a preset sliding window length.

[0082] It can be understood that the second historical period includes the starting moment of the first historical period and each moment within a preset sliding window length before the starting moment of the first historical period.

[0083] Optionally, in this embodiment, the second historical position of the digital key in the second historical period can be determined based on the historical position of the digital key in the second historical period and the historical position of the digital key in a preset sliding window length before the start time of the first historical period. Exemplarily, the position of the digital key at any moment in the second historical period can be used as the second historical position of the digital key in the second historical period. For example, the historical position at the start time of the first historical period or the historical position of the digital key at the start time of the second historical period can be used as the second historical position of the digital key in the second historical period.

[0084] S340, determining a position change of the digital key in a current time period according to the position of the digital key in different time periods.

[0085] Among them, the positions in different time periods include the second historical position, the first historical position and the current position.

[0086] Exemplarily, the change of the digital key from the second historical position to the first historical position and from the first historical position to the current position can be regarded as the position change of the digital key in the current time period.

[0087] In the above embodiment, the specific method of obtaining the position change of the digital key of the target vehicle in the current time period is described in detail. Specifically, by presetting the sliding window length, the current time period is divided into a first current time period, a first historical time period and a second historical time period, and the position of the digital key in each time period is determined respectively, and the position change of the digital key in the current time period is determined, which simplifies the process of determining the position change.

[0088] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the location in different time periods is the area under the preset control area of ​​the digital key controller IKM; Figure 4A As shown, the preset control area includes the vehicle lock control area and the non-vehicle lock control area; the vehicle lock control area includes the unlocking area and the locking area. In the figure, point A is in the non-vehicle lock control area; point B is in the locking area; and point C is in the unlocking area.

[0089] It is understandable that if the digital key of the target vehicle is in the unlocking area, the IKM controller will control the lock of the target vehicle to open; if the digital key of the target vehicle is in the locking area, the IKM controller will control the lock of the target vehicle to close; if the digital key of the target vehicle is in the non-locking control area, the IKM controller will not control the lock of the target vehicle, for example, it can be to control the lights of the target vehicle, or not to control the target vehicle. The control logic of the non-locking control area can be set as needed, and this application does not impose any limitation on this.

[0090] It should be noted that there may also be an unlocking and locking buffer area between the unlocking area and the locking area. The purpose of setting the unlocking and locking buffer area is to provide a sufficient safety space during the unlocking and locking process of the target vehicle to avoid accidental interference during the operation.

[0091] Furthermore, in order to make the control of the target vehicle more precise, in an optional embodiment, the non-lock control area includes a light control area and an invalid area. Figure 4B As shown, the headlight control area is located between the locked control area and the invalid area, and the area outside the headlight control area is the invalid area. In the figure, point D is in the headlight control area; point E is in the locked area; and point F is in the unlocked area.

[0092] It can be understood that if the digital key of the target vehicle is in the headlight control area, the IKM controller will control the headlights of the target vehicle, for example, turning the headlights on or off; if the digital key of the target vehicle is in the invalid area, the IKM controller cannot sense the digital key and will not control the target vehicle.

[0093] Furthermore, the control logic of the IKM controller is described in detail when the digital key of the target vehicle is in the headlight control area. If the digital key of the target vehicle enters the headlight control area from the invalid area, the IKM controller controls the headlights to turn on; if the digital key of the target vehicle enters the headlight control area from the locked area, the IKM controller controls the headlights to turn off.

[0094] Based on the technical solutions of the above embodiments, the present application also provides an optional embodiment. In this optional embodiment, the vehicle control method provided by the present application is applied to Figure 4B In the application environment shown, the vehicle control method provided by the present application is introduced in detail.

[0095] See also Figure 5 The vehicle control method shown includes:

[0096] S510, respectively obtaining the preset control area of ​​the IKM controller where the digital key of the target vehicle is located in the first history sliding window, the second history sliding window and the current sliding window.

[0097] The first historical sliding window is the second historical period; the second historical sliding window is the first historical period; and the current sliding window is the first current period. The preset control areas of the IKM controller include an unlocking area, a locking area, a headlight control area, and an invalid area.

[0098] S520: Determine area values ​​corresponding to different sliding windows according to the preset control areas where the digital key is located under different sliding windows and area values ​​corresponding to the preset control areas.

[0099] Different preset control areas correspond to different area values. For example, the area value corresponding to the interior of the vehicle may be 0, the area value corresponding to the unlocking area may be 1, the area value corresponding to the locking area may be 2, the area value corresponding to the headlight control area may be 3, and the area value corresponding to the invalid area may be 4, as shown in Table 1 below:

[0100] Table 1: Region value mapping table

[0101]

[0102] Furthermore, if an unlocking buffer area is provided between the unlocking area and the locking area, the area value corresponding to the unlocking buffer area is the same as the area value corresponding to the unlocking area. The reason is that if the interval value of the unlocking buffer area is increased, the locking distance may be too far, resulting in insensitive control of the target vehicle's locks, which does not meet product requirements.

[0103] It should be noted that in order to improve the accuracy of determining the position change trend of the digital key based on the preset area value, the area value corresponding to the digital key will be initialized to 4, which is the area value corresponding to the invalid area.

[0104] S530A, determining a first position change trend of the digital key according to a first region value corresponding to the first historical sliding window and a second region value corresponding to the second historical sliding window; and

[0105] Since the lock control of the target vehicle can more effectively affect the safety of the target vehicle, this embodiment only considers the two situations of the digital key being in the unlocking area and in the non-unlocking area to illustrate the vehicle control method of this application. If the digital key is in the unlocking area, the corresponding area value is less than 2; if the digital key is in the non-unlocking area, the corresponding area value is greater than 1.

[0106] Exemplarily, if the first area value is greater than 1 and the second area value is less than 2, the first position change trend is determined to be close to the vehicle; if the first area value is less than 2 and the second area value is greater than 1, the first position change trend is determined to be away from the vehicle.

[0107] It should be noted that the preset control area where the digital key is located in the first historical sliding window and the preset control area where the digital key is located in the second historical sliding window may be the same, for example, both are in the same preset control area, or both are outside the unlocking area, that is, the area values ​​are both less than 2. In this case, according to the first position change trend of the first area value and the second area value, the first position change trend of the digital key can be further determined according to the specific position of the digital key in the first historical sliding window and the specific position of the digital key in the second historical sliding window.

[0108] S530B: Determine a second position change trend of the digital key according to the second area value corresponding to the second historical sliding window and the third area value corresponding to the current sliding window.

[0109] The specific method for determining the second position change trend is the same as the specific method for determining the first position change trend, and will not be described in detail here.

[0110] S540: Determine a change in the moving direction of the digital key according to a change in the first position change trend and a change in the second position change trend.

[0111] If the first position change trend and the second position change trend are the same, it is determined that the moving direction of the digital key has not changed; if the first position change trend and the second position change trend are different, it is determined that the moving direction of the digital key has changed.

[0112] For example, if the first area value is greater than 1, the second area value is less than 2, and the third area value is greater than 1, it is determined that the moving direction of the digital key has changed. If the first area value is less than 2, the second area value is greater than 1, and the third area value is less than 2, it is determined that the moving direction of the digital key has changed.

[0113] S550: Determine the current area of ​​the digital key according to the change in the moving direction.

[0114] If the moving direction of the digital key changes, the third area value of the digital key is considered unreliable, and the preset control area corresponding to the second area value of the digital key is used as the current area of ​​the digital key.

[0115] If the moving direction of the digital key changes, the third area value of the digital key is considered to be credible, that is, the preset control area corresponding to the third area value of the digital key is used as the current area of ​​the digital key.

[0116] It should be noted that if the first area value and the second area value are both less than 2, or the first area value and the second area value are both greater than 1, and the first position change trend of the digital key cannot be determined, then the third area value of the digital key is considered to be credible, that is, the preset control area corresponding to the third area value of the digital key is used as the current area of ​​the digital key.

[0117] In order to make the process of determining the current area of ​​the digital key simpler, this embodiment provides a determination logic of a target third area value (i.e., an accurate third area value). After determining the target third area value, the preset control area corresponding to the target third area value is used as the current area of ​​the digital key. For example, the determination logic of the target third area value can be shown in Table 2 below:

[0118] Table 2: Logic table for determining target third region value

[0119]

[0120] Based on the above Table 1, it can be seen that when the moving direction of the digital key represented by the first area value, the second area value and the third area value changes, the third area value is determined to be unreliable, and the second area value is used as the target third area value, avoiding abnormal control of the target vehicle caused by the area value jump caused by the influence of the Bluetooth field strength, that is, making the vehicle control of the target vehicle more accurate.
