Description

A positioning method and device

[0001] This application claims priority to Chinese Patent Application No. 202410696839.7, filed on May 30, 2024, entitled "A Positioning Method and Apparatus", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of automotive control technology, and in particular to a positioning method and device. Background Technology

[0003] In recent years, with the continuous development of automotive intelligence, improving the positioning accuracy of vehicle keys has helped bring broader development opportunities to the automotive industry. In various scenarios, for security reasons, cars need to confirm the key's position on a zoning map. For example, before starting the vehicle, it's necessary to confirm whether the key is inside the car. Current key positioning technology uses a zoning map that includes the front of the car, the interior, the trunk, and the unlocking area. Because the accuracy deviation of current key positioning technology is greater than 20 centimeters, misjudgments can easily occur at some boundary locations, such as door storage compartments, thus reducing the user experience. Summary of the Invention

[0004] This application provides a positioning method and apparatus that can not only improve the positioning accuracy of the key module by the domain control unit, but also avoid misjudging the area and improve the user experience.

[0005] In a first aspect, embodiments of this application provide a positioning method, including:

[0006] The key module receives a first request sent by the domain controller unit, which includes the user's operation intention.

[0007] Based on the user's operation intent, the key module determines the location information of the key module in the area division diagram. The area division diagram includes the front area, interior area, trunk area, trunk unlocking area, and locking area and 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.

[0008] The key module sends location information to the domain controller unit.

[0009] By adding transition areas at the boundaries of some functionally sensitive areas and further subdividing the areas according to different functional requirements, the key module determines its position in the area division map based on the user's operation intent, and then returns the key module's position information to the domain controller. This not only improves the domain controller's positioning accuracy of the key module but also avoids misjudgment of areas, thus enhancing the user experience.

[0010] In one possible design, if the user's intention is to start the vehicle, it is determined whether the key module is located in the vehicle start area, which includes the interior area and the transition area corresponding to each door. If the key module is determined to be in the vehicle start area, then the vehicle start area is identified as location information. By clearly defining the user's intention as starting the vehicle, and then determining whether the key module is located in the vehicle start area in the area division diagram, the positioning accuracy of the key module can be improved, avoiding misjudgment of the area and enhancing the user experience.

[0011] In another possible design, if the user's intention is to unlock the first door via the microswitch, then it is determined whether the key module is located in the unlocking area corresponding to the first door. The unlocking area includes both the locking area and the transition area corresponding to the first door. If the key module is determined to be in the unlocking area, then that area is identified as the location information. By explicitly stating that the user's intention is to unlock the first door via the microswitch, and then determining whether the key module is located in the unlocking area corresponding to the first door in the area division diagram, the positioning accuracy of the key module is improved, misjudgment of areas is avoided, and the user experience is enhanced.

[0012] In another possible design, if the user's intention is to use a micro-switch to lock or unlock the first door, then it is determined whether the key module is located within the locking area corresponding to the first door. If the key module is determined to be within the locking area corresponding to the first door, then the locking area corresponding to the first door is defined as the location information. By explicitly stating that the user's intention is to use a micro-switch to lock or unlock the first door, and then determining whether the key module is located within the locking area corresponding to the first door in the area division diagram, the positioning accuracy of the key module can be improved, avoiding misjudgments of areas and enhancing the user experience.

[0013] In another possible design, if the user's intention is to unlock the tailgate via the microswitch, then it is determined whether the key module is located in the trunk unlocking area; if the key module is determined to be in the trunk unlocking area, then the trunk unlocking area is defined as the location information. By clearly defining the user's intention as unlocking the tailgate via the microswitch, and then determining whether the key module is located in the trunk unlocking area in the area division diagram, it is beneficial to improve the positioning accuracy of the key module, avoid misjudgment of the area, and improve the user experience.

[0014] Secondly, embodiments of this application provide a positioning method, including:

[0015] The domain control unit sends a first request to the key module. The first request includes the user's operation intention. The user's operation intention is used to determine the location information of the key module in the area division map. The area division map includes the front area, the interior area, the trunk area, the trunk unlocking area, and the locking area and 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.

[0016] The domain control unit receives location information sent by the key module.

[0017] By sending a first request containing the user's operational intent to the key module, the key module can determine its location information in the area partitioning map based on the user's operational intent, thereby enabling the domain controller to locate the key module. This improves the domain controller's positioning accuracy of the key module, avoids area misjudgment, and enhances the user experience.

[0018] In one possible design, the domain control unit determines whether to execute the user's intended action based on location information. By determining whether the key module's location information meets the requirements, and thus confirming whether the user's intended action can be executed, vehicle security can be improved.

[0019] In another possible design, before the domain controller sends the first request to the key module, it receives the user's operation intent sent by the terminal device. By receiving the user's operation intent, the reason for locating the key module can be clarified, which helps to avoid misjudgment of the region and improves the user experience.

[0020] Thirdly, embodiments of this application provide a positioning device, which is applied to a key module, or a chip or circuit configured in a key module, comprising:

The transition area corresponding to each door is located between the interior area and the locking area corresponding to each door.

[0023] The sending module is used to send location information to the domain control unit.

[0024] In one possible design, the processing module is further configured to determine whether the key module is in the vehicle start area if the user's operation intent is to start the vehicle. The vehicle start area includes the interior area and the transition area corresponding to each door. If the key module is determined to be in the vehicle start area, the vehicle start area is defined as location information.

[0025] In another possible design, the processing module is also used to determine whether the key module is in the unlocking area corresponding to the first door if the user's operation intention is to unlock the micro switch of the first door. The unlocking area corresponding to the first door includes the locking area and the transition area corresponding to the first door. If it is determined that the key module is in the unlocking area corresponding to the first door, the unlocking area corresponding to the first door is determined as the location information.

[0026] In another possible design, the processing module is also used to determine whether the key module is in the locking area corresponding to the first door if the user's operation intention is to open or close the first door with a micro-motion; if it is determined that the key module is in the locking area corresponding to the first door, the locking area corresponding to the first door is determined as the location information.

[0027] In another possible design, the processing module is also used to determine whether the key module is in the trunk unlocking area if the user's operation intention is to unlock the tailgate micro switch; if it is determined that the key module is in the trunk unlocking area, the trunk unlocking area is determined as location information.

[0032] In one possible design, the processing module is used to determine whether to execute the user's operation intention based on the location information.

[0033] In another possible design, the receiving module is also used to receive the user's operation intent sent by the terminal device before sending the first request to the key module.

In order to better understand the technical means of this application and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this application more obvious and understandable, the following are specific embodiments of this application. Attached Figure Description

[0052] Figure 8 is a schematic diagram of the structure of a domain control unit provided in an embodiment of this application. Specific Implementation

[0053] The embodiments of this application are described below with reference to the accompanying drawings.

[0054] It should be understood that in the description of this application, "at least one" means one or more, and "multiple" means two or more. In addition, the words "first," "second," etc., unless otherwise stated, are used only for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance or order.

[0055] Currently, for safety reasons, vehicles need to confirm the key's location in various scenarios, and then determine whether to perform related actions based on whether the key's location meets the requirements. For example, starting the vehicle requires confirming that the key is inside the vehicle; locking / unlocking with a microswitch requires confirming that the key is near the vehicle; preventing forgetting the key inside the vehicle requires confirming that the key is not inside the vehicle; opening the trunk with a microswitch requires confirming that the key is near the trunk; and preventing forgetting the trunk key requires confirming that the key is not inside the trunk.

[0056] In existing technologies, key positioning typically involves dividing the vehicle into zones, as shown in Figure 1. This zone division includes the front of the vehicle, the interior, the trunk, and the unlocking area. However, current key positioning technology has an accuracy deviation exceeding 20 centimeters, leading to potential misjudgments at certain boundary locations. For example, if a customer places the key in the door storage compartment and attempts to start the vehicle, misjudging the key's position as the unlocking area will result in starting failure. Similarly, if a customer approaches the vehicle with their phone in hand and attempts to press the microswitch to unlock, misjudging the key's position as the interior area will also cause unlocking failure.

[0057] To address the aforementioned technical problems, the embodiments of this application provide the following solutions.

[0058] Figure 2 is a schematic diagram of a positioning system provided in an embodiment of this application. The positioning method provided in this application is applicable to this positioning system. The positioning system includes a key module 201 and a domain control unit 202. Specifically, the key module 201 is connected to the domain control unit 202, where the connection refers to the transmission of commands and / or data signals. A detailed description of each module is as follows.

[0059] The key module 201 is used to receive a first request sent by the domain control unit, the first request including the user's operation intention; based on the user's operation intention, determine the location information of the key module in the area division map, the area division map including the front area, the interior area, the trunk area, the trunk unlocking area, and the locking area and transition area corresponding to each door, the vehicle starting area including the interior area and the transition area corresponding to each door, the unlocking area corresponding to each door including 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; and send the location information to the domain control unit.

[0060] It should be understood that, in the embodiments of this application, the key module 201 can also be used to perform the steps or functions implemented by the key module in the positioning method provided in this application. Please refer to the corresponding description below for details, which will not be described in detail here.

[0061] 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.

[0062] 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.

[0063] The key module 201 and the domain control unit 202 can establish a communication connection through a wired network or a wireless network.

[0064] 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 is merely an illustrative structural diagram of a positioning system, and in practical applications, the positioning system in Figure 2 can be modified accordingly based on specific circumstances.

[0065] As shown in Figure 3, Figure 3 is a flowchart illustrating a positioning method provided in an embodiment of this application. This method is applicable to the positioning system shown in Figure 2, and is specifically implemented through the interaction of the key module 201 and the domain control unit 202 within the system. The method includes, but is not limited to, the following steps:

[0066] Step S301: The key module receives a first request sent by the domain controller unit, the first request including the user's operation intention.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] Terminal devices are devices with processing and data transmission / reception capabilities. Examples of terminal devices include smartwatches, computers, laptops, tablets, PDAs, desktops, mobile phones, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs).

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] Figure 4 is a region division diagram provided in an embodiment of this application. As shown in Figure 4, the region division diagram includes the front area, the interior area, the trunk area, the trunk unlocking area, the locking area 1 and transition area 1 corresponding to the left front door, the locking area 2 and transition area 2 corresponding to the left rear door, the locking area 3 and transition area 3 corresponding to the right front door, the locking area 4 and transition area 4 corresponding to the right rear door, and an invalid area. The vehicle features a front area at the front of the car, a trunk area at the trunk, an interior area between the front and trunk areas, a trunk unlocking area behind the trunk, a locking area 1 on the outside of the left front door, a transition area 1 between the interior and locking areas, a locking area 2 on the outside of the left rear door, a transition area 2 between the interior and locking areas, a locking area 3 on the outside of the right front door, a transition area 3 between the interior and locking areas, and a locking area 4 on the outside of the right rear door, a transition area 4 between the interior and locking areas.

[0076] It should be noted that the vehicle start-up area includes the interior area and four transition areas, and the unlocking area for each door includes the locking area and transition area for each door.

[0077] Specifically, based on the user's operation intent, the key module determines whether the key module is located in the area corresponding to the user's operation intent in the area division map. If the key module is located in the area corresponding to the user's operation intent in the area division map, then that area is determined as the location information of the key module.

[0078] In one possible approach, if the user's intention is to start the vehicle, then it is determined whether the key module is in the vehicle start area; if it is determined that the key module is in the vehicle start area, then the vehicle start area is determined as location information.

[0079] The vehicle start-up area includes the interior area, transition area 1, transition area 2, transition area 3 and transition area 4.

[0080] For example, if the user's intention is to start the vehicle, the key module determines whether it is in the vehicle interior area, transition area 1, transition area 2, transition area 3, or transition area 4 based on the user's intention. If the key module is in the vehicle interior area, transition area 1, transition area 2, transition area 3, or transition area 4, then the vehicle start area is determined as the location information.

[0081] In another possible approach, if the user's intention is to unlock the first door via a microswitch, then it is determined whether the key module is in the unlocking area corresponding to the first door; if it is determined that the key module is in the unlocking area corresponding to the first door, then the unlocking area corresponding to the first door is determined as the location information.

[0082] The unlocking area corresponding to the first door includes the locking area and the transition area corresponding to the first door. In this embodiment, the unlocking area corresponding to the left front door includes locking area 1 and transition area 1, the unlocking area corresponding to the left rear door includes locking area 2 and transition area 2, the unlocking area corresponding to the right front door includes locking area 3 and transition area 3, and the unlocking area corresponding to the right rear door includes locking area 4 and transition area 4.

[0083] For example, if the user's intention is to unlock the left front door micro switch, the key module determines whether it is in the locking area 1 or the transition area 1 based on the user's intention. If the key module is in the locking area 1 or the transition area 1, the unlocking area corresponding to the left front door is determined as the location information.

[0084] For example, if the user's intention is to unlock the left rear door micro switch, the key module determines whether it is in the locking area 2 or the transition area 2 based on the user's intention. If the key module is in the locking area 2 or the transition area 2, the unlocking area corresponding to the left rear door is determined as the location information.

[0085] For example, if the user's intention is to unlock the micro switch of the right front door, the key module determines whether it is in the locking area 3 or the transition area 3 based on the user's intention. If the key module is in the locking area 3 or the transition area 3, the unlocking area corresponding to the right front door is determined as the location information.

[0086] For example, if the user's intention is to unlock the micro switch of the right rear door, the key module determines whether it is in the locking area 4 or the transition area 4 based on the user's intention. If the key module is in the locking area 4 or the transition area 4, the unlocking area corresponding to the right rear door is determined as the location information.

[0087] It should be noted that the unlocking area of ​​the car door is divided into four unlocking areas, allowing each door to be unlocked independently.

[0088] In another possible approach, if the user's intention is to micro-open or close the first door, then it is determined whether the key module is in the locking area corresponding to the first door; if it is determined that the key module is in the locking area corresponding to the first door, then the locking area corresponding to the first door is determined as the location information.

[0089] For example, if the user's intention is to lock or unlock the left front door microswitch, the key module determines whether it is in locking zone 1 based on the user's intention. If the key module is in locking zone 1, then locking zone 1 is determined as the location information.

[0090] For example, if the user's intention is to open and close the left rear door via a micro-switch, the key module determines whether it is in locking zone 2 based on the user's intention. If the key module is in locking zone 2, then locking zone 2 is determined as the location information.

[0091] For example, if the user's intention is to lock or unlock the right front door using a micro-switch, the key module determines whether it is in locking zone 3 based on the user's intention. If the key module is in locking zone 3, then locking zone 3 is identified as the location information.

[0092] For example, if the user's intention is to lock or unlock the right rear door using a micro-switch, the key module determines whether it is in locking zone 4 based on the user's intention. If the key module is in locking zone 4, then locking zone 4 is identified as the location information.

[0093] In another possible approach, if the user's intention is to unlock the tailgate microswitch, then 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, then the trunk unlocking area is determined as location information.

[0094] Optionally, if it is determined that the key module is not in the area corresponding to the user's operation intention in the area division map, then the actual position of the key module in the area division map is determined as the position information.

[0095] In one possible approach, if the user's intention is to prevent forgetting the car key, then it is determined whether the key module is in the vehicle's interior area; if it is determined that the key module is not in the vehicle's interior area, then the actual location of the key module in the area division map is determined as the location information.

[0096] For example, if the user's intention is to prevent forgetting the car key, the key module determines whether it is in the car's interior area based on the user's intention. If it is determined that the key module is not in the car's interior area, but in transition area 1, then transition area 1 is determined as the location information.

[0097] In another possible approach, if the user's intention is to prevent forgetting the trunk key, then 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, then the actual position of the key module in the area division map is determined as the location information.

[0098] For example, if the user's intention is to prevent forgetting the trunk key, the key module determines whether it is in the trunk area based on the user's intention. If it is determined that the key module is not in the trunk area, but in transition area 2, then transition area 2 is determined as the location information.

[0099] Step S303: The key module sends location information to the domain control unit.

[0100] Specifically, the domain control unit receives the location information sent by the key module, determines whether the location of the key module meets the requirements based on the location information, and then determines whether to execute the user's operation intention.

[0101] For example, if the user's intention is to start the vehicle and the location information is the vehicle start area, after receiving the location information sent by the key module, the domain control unit first determines whether the key module's location information meets the requirements. If the key module's location information meets the requirements, the domain control unit then determines whether the vehicle itself meets the vehicle start conditions. If the vehicle itself meets the vehicle start conditions, then the vehicle is started.

[0102] In this embodiment, by adding transition areas at the boundaries of some functionally sensitive areas and further subdividing the areas according to different functional requirements, the domain control unit sends a first request containing the user's operation intent to the key module. Based on the user's operation intent, the key module determines its position information in the area division map and then returns the key module's position information to the domain control unit. This not only improves the domain control unit's positioning accuracy of the key module but also avoids misjudgment of areas, thus enhancing the user experience.

[0103] The methods of the embodiments of this application have been described in detail above. The following is a description of the apparatus provided in the embodiments of this application.

[0104] Figure 5 is a schematic diagram of a positioning device provided in an embodiment of this application.

[0105] The receiving module 501 is used to receive a first request sent by the domain controller unit, the first request including the user's operation intention.

[0106] The processing module 502 is used to determine the location information of the key module in the area division map based on the user's operation intention. The area division map includes the front area, the interior area, the trunk area, the trunk unlocking area, and the locking area and 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.

[0107] The sending module 503 is used to send location information to the domain control unit.

[0108] Optionally, the processing module 502 is further configured to determine whether the key module is in the vehicle start area if the user's operation intention is to start the vehicle. The vehicle start area includes the interior area and the transition area corresponding to each door. If it is determined that the key module is in the vehicle start area, the vehicle start area is determined as location information.

[0109] Optionally, the processing module 502 is further configured to determine whether the key module is in the unlocking area corresponding to the first door if the user's operation intention is to unlock the micro switch of the first door. The unlocking area corresponding to the first door includes the locking area and the transition area corresponding to the first door. If it is determined that the key module is in the unlocking area corresponding to the first door, the unlocking area corresponding to the first door is determined as the location information.
