[0051] The embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0052] It should be understood that, in the description of the present application, "at least one" means one or more than one, and "multiple" means two or more than two. In addition, the words "first", "second", etc. are used only for the purpose of distinguishing the description, unless otherwise specified, and cannot be understood as indicating or implying relative importance or indicating or implying order.

[0053] At present, for security considerations, vehicles in various scenarios need to confirm the key position, and then confirm whether the related actions can be performed according to whether the key position meets the requirements. For example, the vehicle needs to confirm that the key is in the vehicle when starting; the micro switch needs to confirm that the key is near the vehicle when unlocking; the in-vehicle key needs to confirm that the key is not in the vehicle when forgetting; the micro switch needs to confirm that the key is near the trunk when opening the trunk; the trunk key needs to confirm that the key is not in the trunk when forgetting.

[0054] In the prior art, when positioning the key, the area is usually divided, Figure 1 is an area division diagram. As shown in the figure, Figure 1 The area division diagram includes a front area, an in-area, a trunk area, and an unlocking area. However, due to the current key positioning technology, the accuracy deviation is greater than 20 cm, which leads to misjudgment of the area in some boundary positions. For example, when the customer puts the key in the door panel storage box and wants to start the vehicle, if the key position is misjudged as the unlocking area, it will cause the start failure; when the customer's phone posture is close to the vehicle and wants to press the microswitch to unlock, if the key position is misjudged as the in-area, it will cause the unlocking failure.

[0055] To solve the above technical problems, the embodiments of the present application provide the following solutions.

[0056] As shown in the figure, Figure 2 , Figure 2 is a structural schematic diagram of a positioning system provided by the embodiments of the present application. The positioning method provided by the present application is applicable to the positioning system. The positioning system includes a key module 201 and a domain control unit 202. Specifically, the key module 201 is connected with the domain control unit 202, and the connection here means transmitting instructions and / or data signals. The detailed description of each module is as follows.

[0057] The key module 201 is configured to receive a first request sent by the domain control unit, the first request including a user operation intention; determine the position information of the key module in an area division diagram based on the user operation intention, the area division diagram including a front area, an in-area, a trunk area, a trunk unlocking area, and a locking area and a transition area corresponding to each door, a vehicle starting area including the in-area and the transition area corresponding to each door, an unlocking area corresponding to each door including the locking area corresponding to each door and the transition area corresponding to each door, and the transition area corresponding to each door being located between the in-area and the locking area corresponding to each door; and send the position information to the domain control unit.

[0058] It should be understood that in the embodiments of the present application, the key module 201 can also be used to execute the steps or functions implemented by the key module in the positioning method provided by the present application. For details, please refer to the corresponding description in the following, which will not be described here.

[0059] Domain control unit 202 is used to send a first request to the key module. The first request includes a user operation intention, which is used to determine the location information of the key module in the area division map. The area division map includes a front area, an interior area, a trunk area, a trunk unlocking area, a vehicle start area, and an unlocking area, a locking area, and a transition area corresponding to each door. The vehicle start area includes the interior area and the transition area corresponding to each door. The unlocking area corresponding to each door includes the locking area and the transition area corresponding to each door. The transition area corresponding to each door is located between the interior area and the locking area corresponding to each door. The domain control unit 202 receives the location information sent by the key module.

[0060] It should be understood that, in the embodiments of this application, the domain control unit 202 can also be used to execute the steps or functions implemented by the domain control unit in the positioning method provided in this application. For details, please refer to the corresponding description below, which will not be described in detail here.

[0061] The key module 201 and the domain control unit 202 can establish a communication connection through a wired network or a wireless network.

[0062] It should be noted that the aforementioned positioning system can be a user-interactive system, which can be a software system, a hardware system, or a combination of both; this application does not impose any specific limitations on this. It should also be noted that... Figure 2 This is merely an illustrative structural diagram of a positioning system; in practical applications, it can be adapted to specific circumstances. Figure 2 The positioning system will be transformed accordingly.

[0063] like Figure 3 As shown, Figure 3 This is a flowchart illustrating a positioning method provided in an embodiment of this application. This method is applicable to... Figure 2 The positioning system shown is specifically implemented through the interaction between the key module 201 and the domain control unit 202 within the system. This method includes, but is not limited to, the following steps:

[0064] Step S301: The key module receives a first request sent by the domain controller unit, the first request including the user's operation intention.

[0065] The user's operational intent can be vehicle start, door micro-switch opening and closing, door micro-switch unlocking, front micro-switch unlocking, rear tailgate micro-switch unlocking, or preventing forgetting the car key or trunk key.

[0066] Specifically, the domain controller sends a first request to the key module, which requests the key module's location information. Then, the key module receives the first request sent by the domain controller.

[0067] Optionally, before the domain controller sends the first request to the key module, the domain controller receives the user's operation intent sent by the terminal device.

[0068] Terminal devices are devices with processing and data transmission / reception capabilities. Examples of terminal devices include smartwatches, computers, laptops, tablets, PDAs, desktop computers, mobile phones, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs).

[0069] Optionally, before the domain controller sends the first request to the key module, the domain controller can also determine the user's operating intent by receiving voice information input by the user.

[0070] For example, when a user inputs the voice command "start the vehicle," the domain control unit receives the voice information, performs speech-to-text processing and intent recognition on the voice information, and then determines that the user's intention is to start the vehicle.

[0071] Step S302: The key module determines the location information of the key module in the area division map based on the user's operation intention.

[0072] The area division diagram includes the front area, interior area, trunk area, trunk unlocking area, and locking and transition areas for each door. The transition area for each door is located between the interior area and the locking area for each door.

[0073] Figure 4 This is a region division map provided in an embodiment of this application. For example... Figure 4 As shown, the area division diagram includes the front area, interior area, trunk area, trunk unlocking area, locking area 1 and transition area 1 corresponding to the left front door, locking area 2 and transition area 2 corresponding to the left rear door, locking area 3 and transition area 3 corresponding to the right front door, locking area 4 and transition area 4 corresponding to the right rear door, and an invalid area. Specifically, the front area is located at the front of the car, the trunk area is located in the trunk, the interior area is located between the front and trunk areas, the trunk unlocking area is located behind the trunk, locking area 1 is located on the outside of the left front door, transition area 1 is located between the interior area and locking area 1, locking area 2 is located on the outside of the left rear door, transition area 2 is located between the interior area and locking area 2, locking area 3 is located on the outside of the right front door, transition area 3 is located between the interior area and locking area 3, locking area 4 is located on the outside of the right rear door, and transition area 4 is located between the interior area and locking area 4.

[0074] It should be noted that the vehicle starting area includes an in-vehicle area and four transition areas, and each door corresponding unlocking area includes each door corresponding locking area and transition area.

[0075] Specifically, the key module determines whether the key module is in the area corresponding to the user operation intention in the area division map based on the user operation intention, and if it is determined that the key module is in the area corresponding to the user operation intention in the area division map, the area is determined as the position information of the key module.

[0076] In one possible way, if the user operation intention is vehicle starting, it is determined whether the key module is in the vehicle starting area; if it is determined that the key module is in the vehicle starting area, the vehicle starting area is determined as the position information.

[0077] The vehicle starting area includes an in-vehicle area, a transition area 1, a transition area 2, a transition area 3 and a transition area 4.

[0078] For example, the user operation intention is vehicle starting, and the key module determines whether the key module is in the in-vehicle area, the transition area 1, the transition area 2, the transition area 3 or the transition area 4 based on the user operation intention, and if the key module is in the in-vehicle area, the transition area 1, the transition area 2, the transition area 3 or the transition area 4, the vehicle starting area is determined as the position information.

[0079] In another possible way, if the user operation intention is the first door microswitch unlocking, it is determined whether the key module is in the first door corresponding unlocking area; if it is determined that the key module is in the first door corresponding unlocking area, the first door corresponding unlocking area is determined as the position information.

[0080] The first door corresponding unlocking area includes the first door corresponding locking area and the transition area. In the embodiments of the present application, the left front door corresponding unlocking area includes the locking area 1 and the transition area 1, the left rear door corresponding unlocking area includes the locking area 2 and the transition area 2, the right front door corresponding unlocking area includes the locking area 3 and the transition area 3, and the right rear door corresponding unlocking area includes the locking area 4 and the transition area 4.

[0081] For example, the user operation intention is the left front door microswitch unlocking, and the key module determines whether the key module is in the locking area 1 or the transition area 1 based on the user operation intention, and if the key module is in the locking area 1 or the transition area 1, the left front door corresponding unlocking area is determined as the position information.

[0082] For example, the user operation intention is to unlock the left rear door micro switch, and the key module determines whether the key module is in the lockout area 2 or the transition area 2 based on the user operation intention. If the key module is in the lockout area 2 or the transition area 2, the unlocking area corresponding to the left rear door is determined as the position information.

[0083] For example, the user operation intention is to unlock the right front door micro switch, and the key module determines whether the key module is in the lockout area 3 or the transition area 3 based on the user operation intention. If the key module is in the lockout area 3 or the transition area 3, the unlocking area corresponding to the right front door is determined as the position information.

[0084] For example, the user operation intention is to unlock the right rear door micro switch, and the key module determines whether the key module is in the lockout area 4 or the transition area 4 based on the user operation intention. If the key module is in the lockout area 4 or the transition area 4, the unlocking area corresponding to the right rear door is determined as the position information.

[0085] It should be noted that the unlocking area of the vehicle door is divided into four unlocking areas, and each vehicle door can be independently unlocked.

[0086] In another possible way, if the user operation intention is to lock the first door micro switch, it is determined whether the key module is in the first door corresponding to the lockout area; if it is determined that the key module is in the first door corresponding to the lockout area, the first door corresponding to the lockout area is determined as the position information.

[0087] For example, the user operation intention is to unlock the left front door micro switch, and the key module determines whether the key module is in the lockout area 1 based on the user operation intention. If the key module is in the lockout area 1, the lockout area 1 is determined as the position information.

[0088] For example, the user operation intention is to unlock the left rear door micro switch, and the key module determines whether the key module is in the lockout area 2 based on the user operation intention. If the key module is in the lockout area 2, the lockout area 2 is determined as the position information.

[0089] For example, the user operation intention is to unlock the right front door micro switch, and the key module determines whether the key module is in the lockout area 3 based on the user operation intention. If the key module is in the lockout area 3, the lockout area 3 is determined as the position information.

[0090] For example, the user operation intention is to unlock the right rear door micro switch, and the key module determines whether the key module is in the lockout area 4 based on the user operation intention. If the key module is in the lockout area 4, the lockout area 4 is determined as the position information.

[0091] In another possible mode, if the user operation intention is to unlock the tailgate microswitch, it is determined whether the key module is in the trunk unlocking area; if it is determined that the key module is in the trunk unlocking area, the trunk unlocking area is determined as the position information.

[0092] Optionally, if it is determined that the key module is not in the area corresponding to the user operation intention in the area division map, the actual position of the key module in the area division map is determined as the position information.

[0093] In a possible mode, if the user operation intention is to prevent the key from being forgotten in the vehicle, it is determined whether the key module is in the in-vehicle area; if it is determined that the key module is not in the in-vehicle area, the actual position of the key module in the area division map is determined as the position information.

[0094] For example, the user operation intention is to prevent the key from being forgotten in the vehicle, and the key module determines, based on the user operation intention, whether the key module is in the in-vehicle area. If it is determined that the key module is not in the in-vehicle area but in the transition area 1, the transition area 1 is determined as the position information.

[0095] In another possible mode, if the user operation intention is to prevent the key from being forgotten in the trunk, it is determined whether the key module is in the trunk area; if it is determined that the key module is not in the trunk area, the actual position of the key module in the area division map is determined as the position information.

[0096] For example, the user operation intention is to prevent the key from being forgotten in the trunk, and the key module determines, based on the user operation intention, whether the key module is in the trunk area. If it is determined that the key module is not in the trunk area but in the transition area 2, the transition area 2 is determined as the position information.

[0097] Step S303: The key module sends the position information to the domain control unit.

[0098] Specifically, the domain control unit receives the position information sent by the key module, judges whether the position of the key module meets the requirements according to the position information, and further determines whether to execute the user operation intention.

[0099] For example, the user operation intention is to start the vehicle, and the position information is the vehicle starting area. After receiving the position information sent by the key module, the domain control unit first judges whether the position information of the key module meets the requirements. If the position information of the key module meets the requirements, the domain control unit further determines whether the vehicle itself meets the vehicle starting condition. If the vehicle itself meets the vehicle starting condition, the vehicle starting is executed.

[0100] In the embodiments of the present application, a transition area is added at the boundary of some function sensitive areas, and the areas are subdivided according to different function requirements. The domain control unit sends a first request containing the user operation intention to the key module. The key module judges the position information of the key module in the area division map based on the user operation intention, and then returns the position information of the key module to the domain control unit. Not only the positioning accuracy of the domain control unit to the key module can be improved, but also the situation of area misjudgment can be avoided, and the user experience is improved.

[0101] The above describes the method of the embodiments of the present application in detail. The following is a description of the device provided by the embodiments of the present application.

[0102] As shown in Figure 5 , Figure 5 is a structural schematic diagram of a positioning device provided by the embodiments of the present application. The positioning device can be a key module, or a chip or processing system in the key module. The device can be used to implement any method and function related to the key module in any of the preceding embodiments. The positioning device can include a receiving module 501, a processing module 502, and a sending module 503. The detailed description of each module is as follows.

[0103] The receiving module 501 is configured to receive a first request sent by a domain control unit. The first request includes a user operation intention.

[0104] The processing module 502 is configured to determine position information of the key module in an area division map based on the user operation intention. The area division map includes a vehicle head area, an in-vehicle area, a trunk area, a trunk unlocking area, and a latching area and a transition area corresponding to each vehicle door. The transition area corresponding to each vehicle door is located between the in-vehicle area and the latching area corresponding to each vehicle door.

[0105] The sending module 503 is configured to send the position information to the domain control unit.

[0106] Optionally, the processing module 502 is further configured to, if the user operation intention is vehicle starting, determine whether the key module is in a vehicle starting area. The vehicle starting area includes the in-vehicle area and the transition area corresponding to each vehicle door. If it is determined that the key module is in the vehicle starting area, the vehicle starting area is determined as the position information.

[0107] Optionally, the processing module 502 is further configured to, if the user operation intention is first vehicle door microswitch unlocking, determine whether the key module is in a first vehicle door corresponding unlocking area. The first vehicle door corresponding unlocking area includes the latching area corresponding to the first vehicle door and the transition area corresponding to the first vehicle door.
