Description

Technical Field

[0001] This invention relates to the field of automotive electronics technology, and more particularly to a vehicle proximity unlocking and welcome method, system, vehicle, and storage medium. Background Technology

[0002] Currently, based on the pursuit of comfort and convenience, most vehicles are equipped with a Passive Entry Passive Start (PEPS) system. In addition to keyless entry and one-button start, traditional PEPS functions usually also require a welcome function of unlocking upon approach and locking upon departure.

[0003] However, the existing proximity unlock welcome function can only automatically unlock when the user approaches the vehicle (i.e., when the user enters the vehicle's proximity unlock area). If the vehicle is located in a centralized storage area and multiple people attempt to unlock it at the same time, users usually have difficulty quickly finding their own vehicle, resulting in a poor proximity unlock welcome experience. Summary of the Invention

[0004] This invention provides a vehicle proximity unlocking and welcoming method, system, vehicle, and storage medium to solve the problem that traditional proximity unlocking and welcoming functions are difficult to quickly detect vehicles and have a poor welcoming experience when multiple people are simultaneously unlocking their vehicles.

[0005] In a first aspect, embodiments of the present invention provide a vehicle approach unlocking and welcoming method, comprising:

[0006] When the Central Electron Module (CEM) detects an unlock signal entering the vehicle's pre-unlock area, it controls the vehicle's headlight controller to display a welcome light show and simultaneously controls the vehicle's HeadUnit (HUT) to power on. The pre-unlock area is a region located at a preset distance outside the vehicle's approach unlock area.

[0007] After the welcome light show is completed, the HUT receives a trigger signal sent by the vehicle light controller and drives the external speaker to play a welcome prompt sound according to the trigger signal.

[0008] In one possible implementation, when the CEM detects an unlock signal entering the vehicle's pre-unlock area, it controls the vehicle's headlight controller to display a welcome light show, including:

[0009] When CEM detects an unlock signal entering the vehicle's pre-unlock area, it obtains the on / off status and display mode of the welcome light show.

[0010] When the welcome light show is in the on / off state, a welcome light on signal is generated based on the display mode of the welcome light show.

[0011] The vehicle light controller is controlled to display a welcome light show based on the welcome light activation signal.

[0012] In one possible implementation, when the welcome light show has only one display mode, the process of setting the on / off state of the welcome light show includes:

[0013] The HUT sends a switch signal to the CEM based on the first input signal;

[0014] The CEM updates the switch status of the welcome light show to the status corresponding to the received switch signal.

[0015] When the welcome light show has at least two display modes, the process of setting the on / off state of the welcome light show and the display modes includes:

[0016] The HUT sends a display mode signal or a shutdown signal to the CEM based on the second input signal;

[0017] The CEM updates the display mode of the welcome light show to the display mode corresponding to the received display mode signal, or updates the on / off state of the welcome light show to the state corresponding to the received off signal.

[0018] In one possible implementation, the switch signal, the display mode signal, or the shutdown signal is an event-type signal with a preset number of frames.

[0019] In one possible implementation, after the welcome light show is completed, the HUT receives a trigger signal sent by the vehicle light controller, including:

[0020] After the welcome light show is completed, the vehicle light controller sends a trigger signal to the HUT; wherein the time when the welcome light show is completed is later than or equal to the time when the HUT is turned on, so that the HUT can receive the trigger signal sent by the vehicle light controller.

[0021] In one possible implementation, after the welcome light show is completed, the HUT receives a trigger signal sent by the vehicle light controller, including:

[0022] After the welcome light show is completed, the vehicle light controller sends a trigger signal to the CEM;

[0023] The CEM detects whether the HUT is powered on.

[0024] When the HUT is powered on, the CEM forwards the received trigger signal to the HUT so that the HUT receives the trigger signal forwarded by the CEM.

[0025] In one possible implementation, after the HUT receives the trigger signal sent by the headlight controller, the method further includes:

[0026] Get the on / off status of the welcome light show and welcome sound, as well as the on / off status of the welcome sound.

[0027] When both the linkage switch for the welcome light show and the welcome prompt sound and the switch switch for the welcome prompt sound are on, the HUT drives the external speaker to play the welcome prompt sound according to the trigger signal.

[0028] Secondly, embodiments of the present invention provide a vehicle proximity unlocking welcome system, including: CEM, headlight controller, HUT and external speaker;

[0029] When the CEM detects an unlock signal entering the vehicle's pre-unlock area, it controls the headlight controller to display a welcome light show and simultaneously controls the HUT to turn on; the pre-unlock area is a region located at a preset distance outside the vehicle's approach unlock area;

[0030] After the welcome light show is completed, the HUT receives a trigger signal sent by the vehicle light controller and drives the external speaker to play a welcome prompt sound according to the trigger signal.

[0031] Thirdly, embodiments of the present invention provide a vehicle including the vehicle proximity unlocking welcome system described in the second aspect above.

[0032] Fourthly, embodiments of the present invention provide a computer-readable storage medium storing a computer program that, when executed by a processor, implements the steps of the method as described in the first aspect or any possible implementation thereof.

[0033] This invention provides a vehicle proximity unlocking welcome method, system, vehicle, and storage medium. When the vehicle's CEM (Content Activation Mechanism) detects an unlocking signal entering a pre-unlocking area at a preset distance outside the vehicle's proximity unlocking zone, it controls the vehicle's headlight controller to display a welcome light show and simultaneously activates the vehicle's HUT (Headlight Adapter). This allows the user to identify the direction of their vehicle through the welcome light show before it automatically unlocks, while also activating the HUT in advance. After the welcome light show concludes, the HUT receives a trigger signal from the headlight controller and drives an external speaker to play a welcome prompt sound. As the user approaches the vehicle further, the pre-activated HUT drives the external speaker to play the welcome prompt sound after the welcome light show, providing further feedback on the vehicle's position and enabling the user to more quickly and accurately identify their vehicle, resulting in a better welcome experience.

[0040] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of the invention. However, those skilled in the art will understand that the invention can be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the invention with unnecessary detail.

[0041] To make the objectives, technical solutions, and advantages of the present invention clearer, specific embodiments will be described below in conjunction with the accompanying drawings.

[0042] Figure 1 This diagram illustrates an application scenario of the vehicle proximity unlocking and welcoming method provided in an embodiment of the present invention. Figure 1 As shown, the traditional proximity unlock welcome function automatically unlocks the vehicle when the user enters its proximity unlock area as the user approaches. However, if the vehicle is located in a centralized storage area and multiple people attempt to unlock it simultaneously, users often find it difficult to quickly locate their own vehicle, resulting in a poor proximity unlock welcome experience.

[0043] See Figure 2 The diagram illustrates the implementation flowchart of the vehicle approach unlocking and welcoming method provided in an embodiment of the present invention, which is described in detail below:

[0044] In step 201, when the CEM detects an unlock signal entering the vehicle's pre-unlock area, it controls the vehicle's headlight controller to display a welcome light show and simultaneously controls the vehicle's HUT to turn on.

[0045] The pre-unlocked area is a region located at a preset distance outside the vehicle's approach unlock area.

[0046] This can be achieved by detecting whether the corresponding unlock signal has entered the vehicle's pre-unlock area using the user's key or mobile device. Combined with... Figures 1-3 When a user approaches the vehicle from a distance and the user (i.e., the unlock signal) enters the vehicle's pre-unlocked area, the CEM can be triggered. The CEM controls the headlight controller to display a welcome light show while simultaneously controlling the HUT to turn on, thus enabling the HUT to prepare for power-on in advance. After the welcome light show is completed, the end signal of the welcome light show can be used as a trigger signal to drive the external speaker through the HUT to play a welcome prompt sound.

[0047] Among them, external speakers such as VSG speakers and AVAS speakers share the output channel of the original external speakers for the welcome prompt sound, so no additional hardware equipment is required.

[0048] This embodiment controls the vehicle light controller to display a welcome light show and drives an external speaker to play a welcome prompt sound, which can achieve a better welcome function without increasing the additional hardware cost.

[0049] Optionally, when the CEM detects an unlock signal entering the vehicle's pre-unlock area, it controls the vehicle's headlight controller to display a welcome light show, which may include:

[0050] When the CEM detects an unlock signal entering the vehicle's pre-unlock area, it acquires the on / off status and display mode of the welcome light show; when the welcome light show is on, it generates a welcome light activation signal based on the display mode; and controls the vehicle's headlight controller to display the welcome light show according to the welcome light activation signal.

[0051] For example, a welcome light show may have only one display mode. In this case, the process of setting the on / off state of the welcome light show may include:

[0052] HUT sends a switch signal to CEM based on the first input signal; CEM updates the switch status of the welcome light show to the status corresponding to the switch signal based on the received switch signal.

[0053] For example, a welcome light show can also have at least two display modes. In this case, the on / off state of the welcome light show and the process of setting the display mode can include:

[0054] HUT sends a display mode signal or a shutdown signal to CEM based on the second input signal; CEM updates the display mode of the welcome light show to the display mode corresponding to the received display mode signal, or updates the on / off state of the welcome light show to the state corresponding to the received shutdown signal based on the received shutdown signal.

[0055] Among them, the switch signal, display mode signal, or shutdown signal can all be event-type signals with a preset number of frames.

[0056] In this embodiment, users can use the HUT to switch the welcome light show function on / off, as well as the display mode of the welcome light show. They can also set the linkage switch between the welcome light show and the welcome sound. The welcome light show function and the linkage switch between the welcome light show and the welcome sound can be set to "on" by default, so that the vehicle has better welcome functionality from the factory, allowing users to more accurately identify their vehicle and enhancing the product's competitiveness.

[0057] For example, as shown in Table 1, the welcome light show function's on / off state and display mode can be set via the event-type signal ApprLightSwt when the vehicle's power mode is ON and the main light show switch is on. After each setting, HUT can send 5 valid signals to CEM at 50ms intervals. Both HUT and CEM can memorize the settings for backup.

[0058] For example, if the welcome light show only has one display mode, when the welcome light show is OFF, you can click the welcome light show switch on HUT to switch the switch to ON. At this time, HUT can first send five frames of signal ApprLightSwt=0x2: Animation mode1(on), and then send five frames of signal ApprLightSwt=0x0: No action to prevent accidental operation from other entry points.

[0059] If the welcome light show has multiple display modes, when the welcome light show is OFF, clicking on Welcome Light Show 1 on HUT will send 5 frames of signal ApprLightSwt = 0x2: Animation mode 1; clicking on Welcome Light Show 2 on HUT will send 5 frames of signal ApprLightSwt = 0x3: Animation mode 2, and so on. Similarly, after clicking on the display mode of the welcome light show and sending the corresponding signal, 5 frames of signal ApprLightSwt = 0x0: No action can also be sent to prevent accidental operation from other entry points.

[0060] When the welcome light show is ON, you can click the welcome light show switch on HUT to switch it OFF. At this time, HUT can first send five frames of signal ApprLightSwt=0x1: OFF, and then send five frames of signal ApprLightSwt=0x0: No action to prevent accidental operation at other entrances.

[0061] To accurately preserve user-defined settings, HUT can send memory values ​​to CEM after power failure and power-on (e.g., after reconnecting the battery and receiving a CAN network wake-up signal), after sleep / wake-up via CAN network, after user settings are changed, after factory reset, or after switching the ignition status from non-ON to ON. If the memory values ​​of CEM and HUT are inconsistent, HUT will use the memory values ​​sent by CEM.

[0062] This embodiment can also configure a linkage switch between the welcome light show and the welcome sound via HUT. In addition to the original control strategy for the welcome sound, the on / off state of the linkage switch is monitored. The welcome sound will only play in response to a trigger signal when both the welcome sound and the linkage switch are on. If the linkage switch is off, the welcome sound will not play even if a trigger signal is received. This allows users to determine whether a welcome sound is needed through the linkage switch, increasing the product's flexibility.

[0063] Optionally, when the CEM detects an unlock signal entering the vehicle's pre-unlock area, it controls the vehicle's HUT to power on, which may include:

[0064] When the CEM detects an unlock signal entering the vehicle's pre-unlock area, it generates a HUT power-on signal to control the vehicle's HUT power-on based on the HUT power-on signal.

[0065] In this embodiment, when an unlock signal is detected entering the vehicle's pre-unlocking area, the HUT is controlled to turn on in advance. This facilitates a seamless connection between the welcome light show and the welcome prompts, allowing users to identify their vehicle more quickly and accurately as they approach it, guided by the welcome light show and the welcome prompts, thus providing a better welcome experience.

[0066] In step 202, after the welcome light show is completed, HUT receives a trigger signal sent by the vehicle light controller and drives the external speaker to play a welcome prompt sound according to the trigger signal.

[0067] The welcoming prompt can be a preset frequency cat meow.

[0068] In this embodiment, using a preset frequency cat meow as the welcome sound fully integrates cat elements, enhancing brand characteristics (e.g., the ORA brand), improving product appeal and quality, and facilitating wider user recognition and increased brand premium. Furthermore, the warm cat meow accompanying the welcome light show improves upon monotonous and uninteresting sound effects, offering users a personalized choice. The friendly cat meow also creates a warm, home-like atmosphere, further strengthening the bond between driver and vehicle and enhancing the overall user experience.

[0069] Optionally, after the welcome light show has finished, the HUT receives a trigger signal from the vehicle light controller, which may include:

[0070] After the welcome light show is completed, the vehicle light controller sends a trigger signal to the HUT; the time when the welcome light show ends is later than or equal to the time when the HUT is powered on, so that the HUT can receive the trigger signal sent by the vehicle light controller.

[0071] In this embodiment, by pre-setting the display time of the welcome light show to be greater than or equal to the power-on time of the HUT, the end time of the welcome light show can be later than or equal to the power-on time of the HUT. Therefore, after the welcome light show is completed, a trigger signal can be sent directly to the HUT through the vehicle light controller, reducing signal transmission delay and improving user experience.

[0072] Optionally, after the welcome light show has finished, the HUT receives a trigger signal from the vehicle light controller, which may include:

[0073] After the welcome light show is completed, the vehicle light controller sends a trigger signal to the CEM; the CEM checks whether the HUT is powered on; when the HUT is powered on, the CEM forwards the received trigger signal to the HUT so that the HUT can receive the trigger signal forwarded by the CEM.

[0074] In this embodiment, the trigger signal sent by the vehicle light controller is indirectly forwarded to the HUT via the CEM, which eliminates the need to limit the display time of the welcome light show, thus improving flexibility, while ensuring that the HUT can receive the trigger signal, thereby improving reliability.

[0075] Optionally, before the CEM forwards the received trigger signal to the HUT, the following may also be included: the CEM acquires the linkage switch status of the welcome light show and the welcome prompt sound, as well as the switch status of the welcome prompt sound; when the linkage switch status of the welcome light show and the welcome prompt sound, as well as the switch status of the welcome prompt sound, are both on, the CEM forwards the received trigger signal to the HUT.

[0076] In this embodiment, before the CEM indirectly forwards the trigger signal sent by the vehicle light controller to the HUT, the CEM detects whether the linkage switch status of the welcome light show and the welcome prompt sound, as well as the switch status of the welcome prompt sound, are both in the on state. If the linkage switch status of the welcome light show and the welcome prompt sound, as well as the switch status of the welcome prompt sound, are both in the on state, the received trigger signal is then forwarded to the HUT. This can save the HUT's judgment logic and avoid playback errors caused by errors in the switch status stored by the HUT.

[0077] Optionally, after the HUT receives the trigger signal sent by the headlight controller, it may also include:

[0078] The system obtains the on / off status of the linkage between the welcome light show and the welcome sound, as well as the on / off status of the welcome sound. When both the linkage between the welcome light show and the welcome sound and the on / off status of the welcome sound are on, the HUT drives the external speaker to play the welcome sound according to the trigger signal.

[0079] In this embodiment, when the trigger signal is sent directly to the HUT through the vehicle light controller, the HUT can determine the linkage switch status of the welcome light show and the welcome prompt sound, as well as the switch status of the welcome prompt sound. It can quickly respond to the trigger signal and then provide a welcome prompt sound to further indicate the vehicle's location.

[0080] In this embodiment of the invention, when the CEM detects a vehicle's unlock signal entering a pre-unlocking area at a preset distance outside the vehicle's approach unlocking area, it controls the vehicle's headlight controller to display a welcome light show and simultaneously activates the vehicle's HUT (Headlight Adapter). This allows the user to identify the direction of their vehicle through the welcome light show before it automatically unlocks, while also activating the HUT in advance. After the welcome light show concludes, the HUT receives a trigger signal from the headlight controller and drives an external speaker to play a welcome alert tone. As the user approaches the vehicle further, the pre-activated HUT drives the external speaker to play the welcome alert tone after the light show, providing further feedback on the vehicle's location and allowing the user to more quickly and accurately identify their vehicle, resulting in a better welcome experience. Simultaneously, a cat-like meow tone at a preset frequency is used as the welcome alert tone, fully incorporating cat elements. Accompanied by a welcoming light show, a friendly cat-like meow alert can be emitted to enhance brand characteristics (such as the ORA brand), improve the appeal and quality of products, improve the monotonous and boring status quo of alert sounds, provide users with personalized choices, and create a warm and welcoming atmosphere like coming home. This will further strengthen the bond between people and cars, enhance the user experience, and help gain more user recognition and improve brand premium.

[0081] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of the present invention.

[0082] The following are device embodiments of the present invention. For details not described in detail, please refer to the corresponding method embodiments described above.

[0083] Figure 4 A schematic diagram of a vehicle proximity unlocking welcome system provided in an embodiment of the present invention is shown. For ease of explanation, only the parts related to the embodiment of the present invention are shown, and are described in detail below:

[0084] like Figure 4 As shown, the vehicle's proximity unlocking welcome system includes: CEM41, headlight controller 42, HUT43, and external speaker 44.

[0085] When CEM41 detects an unlock signal entering the vehicle's pre-unlock area, it controls the headlight controller 42 to display a welcome light show and simultaneously controls HUT43 to turn on. The pre-unlock area is a region located at a preset distance outside the vehicle's approach unlock area.

[0086] After the welcome light show is completed, HUT43 receives a trigger signal from the headlight controller 42 and drives the external speaker 44 to play a welcome prompt sound according to the trigger signal.

[0087] In this embodiment of the invention, when the CEM detects a vehicle's unlock signal entering a pre-unlocking area at a preset distance outside the vehicle's approach unlocking area, it controls the vehicle's headlight controller to display a welcome light show and simultaneously activates the vehicle's HUT (Head-Up Display). This allows the user to identify the direction of their vehicle through the welcome light show before it automatically unlocks, while also activating the HUT in advance. After the welcome light show concludes, the HUT receives a trigger signal from the headlight controller and drives an external speaker to play a welcome greeting sound. Thus, as the user approaches the vehicle further, the pre-activated HUT drives the external speaker to play the welcome greeting sound after the welcome light show, providing further feedback on the vehicle's position and enabling the user to more quickly and accurately identify their vehicle, resulting in a better welcome experience.

[0088] In one possible implementation, when CEM41 detects an unlock signal entering the pre-unlocked area of ​​the vehicle, it acquires the on / off status and display mode of the welcome light show; when the on / off status of the welcome light show is on, it generates a welcome light on signal based on the display mode of the welcome light show; and controls the vehicle light controller 42 to display the welcome light show according to the welcome light on signal.

[0089] In one possible implementation, HUT43 sends a switch signal to CEM41 based on the first input signal; CEM41 updates the on / off state of the welcome light show to the state corresponding to the switch signal based on the received switch signal; or:

[0090] HUT43 sends a display mode signal or a shutdown signal to CEM41 based on the second input signal; CEM41 updates the display mode of the welcome light show to the display mode corresponding to the received display mode signal, or updates the on / off state of the welcome light show to the state corresponding to the received shutdown signal based on the received shutdown signal.

[0091] In one possible implementation, the switch signal, display mode signal, or close signal is an event-type signal with a preset number of frames.

[0092] In one possible implementation, after the welcome light show is completed, the headlight controller 42 sends a trigger signal to the HUT 43; wherein the time when the welcome light show is completed is later than or equal to the time when the HUT 43 is turned on, so that the HUT 43 receives the trigger signal sent by the headlight controller 42.

[0093] In one possible implementation, after the welcome light show is completed, the headlight controller 42 sends a trigger signal to the CEM41; the CEM41 detects whether the HUT43 is powered on; when the HUT43 is powered on, the CEM41 forwards the received trigger signal to the HUT43 so that the HUT43 receives the trigger signal forwarded by the CEM41.

[0094] In one possible implementation, after HUT43 receives the trigger signal sent by the headlight controller 42, it obtains the linkage switch status of the welcome light show and the welcome prompt sound, as well as the switch status of the welcome prompt sound. When both the linkage switch status of the welcome light show and the welcome prompt sound and the switch status of the welcome prompt sound are on, HUT43 drives the external speaker to play the welcome prompt sound according to the trigger signal.
