Description

Technical Field

[0001] This application relates to the field of digital car keys, and more particularly to an in-vehicle device and an in-vehicle digital key system. Background Technology

[0002] Digital car keys are a new type of car key that differs from traditional car keys. They have evolved from initially integrating door unlocking / locking and trunk unlocking / locking functions to later offering richer and more intelligent features such as condition-based car start, turning on / off the car's air conditioning or other equipment, and adjusting in-car equipment parameters.

[0003] A vehicle digital key system mainly consists of two parts: a digital key and an onboard unit. The digital key is generally carried by the owner to control the vehicle, while the onboard unit is usually located inside the vehicle, such as next to the driver's seat. This unit allows the owner to place the digital key inside the vehicle so that it can recognize the digital certificate and other data used for identity authentication, as well as charge the digital key. The placement and removal of the digital key within the onboard unit needs to consider the stable placement of the digital key, as unstable placement can make it inconvenient to retrieve. Summary of the Invention

[0004] This application provides an in-vehicle device and an in-vehicle digital key system, which can facilitate the retrieval and placement of the digital key while ensuring stable placement of the digital key.

[0005] In a first aspect, this application provides a vehicle-mounted device. The device includes a receiving slot, a clamping module, a lifting module, a human body sensing module, a vehicle communication module, and a vehicle control module.

[0006] The receiving slot is used to hold the digital key; the movable clamping module includes a clamping state and an unfolded state, used to fix the digital key in the receiving slot when clamped; the lifting module includes a lifting state and a lowering state, used to lift the digital key from the receiving slot when lifted; the vehicle communication module is used to wirelessly communicate with the digital key; the human body sensing module is used to generate a human body sensing signal when there is a human body within a preset distance of the receiving slot.

[0007] The vehicle control module is connected to the clamping module, the lifting module, the human body sensing module, and the vehicle communication module; the vehicle control module is configured to:

[0008] Acquire signal strength data of the wireless communication connection between the vehicle communication module and the digital key;

[0009] If the signal strength data is higher than the first strength threshold, a containment signal is generated; if the signal strength data is not higher than the first strength threshold but higher than the second strength threshold, a proximity signal is generated; if the signal strength data is not higher than the second strength threshold, a distance signal is generated.

[0010] When the containment signal is continuous, if a human body sensing signal is received, the clamping module is sequentially controlled to switch to the unfolded state and the lifting module is sequentially controlled to switch to the lifting state. When the continuous containment signal changes to a proximity signal, the lifting module is sequentially controlled to switch to the lowered state and the clamping module is sequentially controlled to switch to the clamping state.

[0011] When the signal continuously moves away from the target area changes to a signal moving closer to the target area and a human body sensing signal is received, the clamping module is sequentially controlled to switch to the unfolded state and the lifting module is switched to the lifting state. When the signal moving closer to the target area changes to a signal moving closer to the target area, the lifting module is sequentially controlled to switch to the lowered state and the clamping module is switched to the clamping state.

[0012] By adopting the above technical solution, it is possible to conveniently pick up and put down the digital key. After the digital key is placed in the receiving slot, it can be fixed by the clamping module, and the car owner does not need to perform any other operations. In other words, the overall solution achieves convenient picking up and putting down of the digital key while ensuring stable placement of the digital key.

[0013] Furthermore, the receiving slot has a top-opening design that adapts to the shape of the digital key;

[0014] The clamping module includes multiple telescopic clamping components that are disposed on the side wall of the receiving groove and can extend into the receiving groove. When the telescopic clamping components are extended, they are in a clamping state, and when they are retracted, they are in an unfolded state.

[0015] The lifting module includes a telescopic lifting member located at the bottom of the receiving groove that can extend to the top of the receiving groove. When the telescopic lifting member is extended, it is in a lifting state, and when it is retracted, it is in an unfolded state.

[0016] Furthermore, both the telescopic clamping component and the telescopic lifting component are electrically controlled telescopic rods.

[0017] Furthermore, the human body sensing module is a thermal infrared sensor.

[0018] Furthermore, it also includes a wireless charging module for charging the digital key.

[0019] In a second aspect, this application provides an in-vehicle digital key system, including a digital key and an in-vehicle device as described in any of the first aspects above.

[0020] Furthermore, the digital key includes a key communication module, a key control module, and a key operation module;

[0021] The key operation module is used to input operation commands; the key communication module is used to wirelessly communicate with the vehicle-mounted device; and the key control module connects the key communication module and the key control module.

[0022] In summary, this application has at least the following beneficial effects:

[0023] An in-vehicle device and an in-vehicle digital key system are provided, wherein the system can sense the adaptive status of the vehicle owner and the digital key, thereby facilitating the retrieval and placement of the digital key while ensuring its stable placement.

[0024] It should be understood that the description in the Summary Section is not intended to limit the key or essential features of the embodiments of this application, nor is it intended to restrict the scope of this application. Other features of this application will become readily apparent from the following description. Attached Figure Description

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0029] This application provides an in-vehicle device and an in-vehicle digital key system, wherein the in-vehicle device can determine the status of the vehicle based on the position of the digital key and the sensing of a human body, thereby making it easy to take the digital key out and put it in the in-vehicle device and ensuring stable placement.

[0030] Since the vehicle-mounted device is part of the vehicle-mounted digital key system, the vehicle-mounted device is disclosed in this application embodiment through the disclosure of the vehicle-mounted digital key system.

[0031] This application discloses an in-vehicle digital key system.

[0032] Figure 1 A schematic diagram of an in-vehicle digital key system according to an embodiment of this application is shown.

[0033] Reference Figure 1 The vehicle digital key system includes a digital key and an onboard unit. The digital key is carried by the owner to control the vehicle, while the onboard unit is located inside the vehicle, typically on the driver's side. It serves as a place for the owner to store the digital key and is used to recognize control commands sent by the digital key.

[0034] Specifically, the digital key includes a key communication module, a key control module, and a key operation module; the key operation module is used to input operation commands; the key communication module is used to wirelessly communicate with the vehicle-mounted device; and the key control module connects the key communication module and the key control module.

[0035] The key operation module can include buttons, touchpad, voice input module, etc. It only needs to be able to input control commands. The input control commands can include door unlocking / locking commands, car start-permission commands, in-vehicle equipment such as air conditioning start-stop commands or parameter adjustment commands, etc.

[0036] The key control module is a chip inside the digital key, which stores the digital key's digital certificate so that the vehicle can identify and authenticate the digital key's identity. When the key control module receives a control command sent by the key operation module, it determines the target of the control command based on the digital certificate. The receiving party, i.e., the vehicle device, also determines the validity of the control command based on the digital certificate.

[0037] The key communication module is used for wireless communication with the vehicle's onboard devices. The key communication module may include one or more of the following: NFC module, Bluetooth module, and WiFi module. It only needs to be able to achieve wireless communication connection.

[0038] The vehicle-mounted device includes a receiving slot, a clamping module, a lifting module, a human body sensing module, a vehicle communication module, and a vehicle control module. The receiving slot is used to hold a digital key; the movable clamping module includes a clamping state and an unfolded state, used to fix the digital key in the receiving slot when clamped; the lifting module includes a lifting state and a lowered state, used to raise the digital key from the receiving slot when lifted; the vehicle communication module is used for wireless communication with the digital key; the human body sensing module generates a human body sensing signal when a human body is within a preset distance of the receiving slot; the vehicle control module connects the clamping module, the lifting module, the human body sensing module, and the vehicle communication module.

[0039] Specifically, the main body of the vehicle-mounted device is fixedly installed on the driver's side for operation by the vehicle owner or driver. A receiving slot is formed on the main body of the device for holding the digital key. In this embodiment, the digital key is generally cuboid in shape, and the receiving slot is generally rectangular. The shape of the receiving slot matches the shape of the digital key, and the depth of the digital key matches the depth of the receiving slot, so that the digital key can be placed in the receiving slot.

[0040] The movable clamping module includes multiple telescopic clamping components that are disposed on the side wall of the receiving groove and can extend into the receiving groove. When the telescopic clamping components are extended, they are in a clamping state, and when they are retracted, they are in an unfolded state. The lifting module includes a telescopic lifting component that is disposed at the bottom of the receiving groove and can extend into the top opening of the receiving groove. When the telescopic lifting component is extended, it is in a lifting state, and when it is retracted, it is in an unfolded state.

[0041] In this embodiment, both the telescopic clamping member and the telescopic lifting member are electrically controlled telescopic rods.

[0042] When the telescopic clamp is extended, it clamps the digital key located in the receiving slot, increasing the stability of the digital key. Conversely, when the telescopic clamp is retracted, it is in the extended state, allowing the digital key to be removed from the receiving slot. When the telescopic lift is retracted (lowered state), the receiving slot allows the digital key to be almost completely within the slot. When the telescopic lift is extended (lifting state), it lifts the digital key out of the opening of the receiving slot, facilitating its retrieval. Simultaneously, the extended telescopic lift allows the remaining depth of the receiving slot to facilitate the insertion of the digital key.

[0043] The vehicle control module is configured to: acquire signal strength data of the wireless communication connection between the vehicle communication module and the digital key; if the signal strength data is higher than a first strength threshold, generate an accommodating signal; if the signal strength data is not higher than the first strength threshold but higher than a second strength threshold, generate a proximity signal; if the signal strength data is not higher than the second strength threshold, generate a distance signal; while the accommodating signal is continuous, if a human body sensing signal is received, sequentially control the clamping module to switch to the unfolded state and the lifting module to switch to the lifting state; and when the continuous accommodating signal changes to a proximity signal, sequentially control the lifting module to switch to the lowered state and the clamping module to switch to the clamping state; when the continuous distance signal changes to a proximity signal and a human body sensing signal is received, sequentially control the clamping module to switch to the unfolded state and the lifting module to switch to the lifting state; and when the proximity signal changes to an accommodating signal, sequentially control the lifting module to switch to the lowered state and the clamping module to switch to the clamping state.

[0044] Under normal circumstances, regardless of whether the digital key is in the receiving slot, the active clamping module is in the clamping state, and the lifting module is in the lowered state.

[0045] In actual operation, if the car owner wants to remove the digital key from the receiving slot, the digital key will be partially lifted out of the receiving slot when the owner's hand approaches, making it easier to retrieve. If the owner wants to put the digital key into the receiving slot, the receiving slot will be partially lifted out of the receiving slot when the owner's hand approaches, allowing the digital key to be inserted, and the usable depth of the receiving slot will become shallower (under the lifting action of the lifting module). The owner can more easily put the digital key into the shallower receiving slot. Subsequently, after the lifting module switches to the lowered state, the digital key will automatically sink down under the influence of gravity until it is almost completely inside the receiving slot, and then be clamped and locked by the movable clamping device. This process ensures the stability of the digital key in the vehicle device, effectively preventing the digital key from falling out of the receiving slot due to horizontal or vertical bumps, and facilitates the retrieval and placement of the digital key without requiring any additional operation from the owner.

[0046] It should be understood that, in order to avoid misplacement of digital keys of the same model, a test signal carrying a digital certificate can be used to obtain signal strength data.

[0047] To ensure reliable power supply for the digital key, the vehicle device also includes a wireless charging module for charging the digital key. This wireless charging module is controlled by the vehicle control module and is activated to charge the digital key when it is in the receiving slot and not fully charged.

[0048] It should be understood that the mechanical structure is not an improvement of this application, and those skilled in the art can implement specific mechanical structures based on the disclosure of the embodiments of this application. Therefore, specific mechanical structures are not disclosed or limited here.

[0049] The above description is merely a preferred embodiment of this application and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of disclosure in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the foregoing disclosed concept. For example, technical solutions formed by substituting the above features with (but not limited to) technical features with similar functions disclosed in this application.
