[0053] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0054] Figure 1 This is a structural diagram of a car welcome mode interactive system provided by one or more embodiments of the present invention.

[0055] According to one aspect of the present invention, there is provided a system comprising:

[0056] A trigger interaction module, configured to obtain a user proximity signal through a user proximity trigger unit and generate an interaction trigger instruction based on the user proximity signal;

[0057] The FDD data interaction module is used to abstract and encapsulate sensor and actuator data, implement bidirectional conversion between Ethernet / CAN signals and services, and build a mapping link between interaction trigger commands and system responses;

[0058] A central interaction processing platform is configured to receive the interaction trigger instruction, call vehicle status data through the FDD data interaction module, and generate an interaction control instruction including sensory feedback;

[0059] The regional interactive execution unit is used to convert interactive control instructions into hardware drive signals and drive the execution module to implement multimodal interactive feedback;

[0060] The multimodal interaction execution module is used to execute welcome lighting effects, voice prompts, and door / seat adjustment interactive actions according to interactive control instructions.

[0061] Further, it includes: the user proximal trigger unit includes: a wireless identification subunit, a biometric verification subunit and a physical trigger subunit;

[0062] The activation of the welcome mode usually relies on a variety of sensing technologies and communication mechanisms. The following are common triggering mechanisms:

[0063] Smart Key Recognition: Vehicles equipped with smart keys typically communicate with the vehicle at a distance. Using low-frequency signals or Bluetooth technology, the vehicle recognizes the smart key's approach and automatically triggers the welcome mode. This process is seamless and instantaneous; the welcome mode automatically activates when the owner approaches the vehicle with the key.

[0064] Mobile device sensing: Some modern cars can also communicate with the owner's smartphone or smartwatch to recognize the owner's approach. Using Bluetooth or near-field communication (NFC), the vehicle can automatically activate Welcome Mode when the owner approaches. This further expands the ways Welcome Mode can be triggered and enhances convenience.

[0065] Biometric technology: High-end models may use biometric technologies such as facial recognition and iris recognition. When the vehicle detects the driver's face or eye features, it automatically activates the welcome mode. This ensures that only authorized owners or passengers can activate the welcome mode, enhancing security.

[0066] Door sensor: When the driver approaches the vehicle and touches the door handle, the sensor detects this action and triggers the welcome mode. This approach, combined with other sensing technologies, can further enhance the intelligence and sensitivity of the welcome mode. In the intelligent vehicle control system, the welcome mode's functions and performance greet the driver through a series of visual, auditory, and physical feedback, including but not limited to lighting effects, sound prompts, physical movements, and personalized settings.

[0067] Light welcome is the most intuitive and important part of the welcome mode. The coordination of interior and exterior lights can create a welcoming atmosphere and provide visual guidance for the owner at night.

[0068] Exterior Lighting: When Welcome Mode is activated, the vehicle's headlights, taillights, daytime running lights, and door handle lights illuminate in sequence, creating a gradual lighting effect, symbolizing the vehicle's "awakening" and welcoming the owner. Some high-end models also feature a ground projection light feature. As the owner approaches, a welcome pattern or brand logo appears on the ground, enhancing the visual impact and making the vehicle more recognizable.

[0069] Interior ambient lighting: The interior ambient lighting automatically illuminates when the welcome mode is activated, often using soft tones to create a comfortable and warm atmosphere. This lighting design not only enhances the sense of luxury in the car, but also provides a good visual environment for the driver to enter the vehicle.

[0070] The multimodal sensory feedback unit includes a visual feedback subunit, an auditory feedback subunit, and a tactile / physical feedback subunit.

[0071] Further, including:

[0072] The FDD data interaction module builds a two-way interactive link including:

[0073] Convert CAN signals into service responses via BO_SA_FDD_WelLitInfo;

[0074] BO_SA_FDD_WelLitCtrl converts the service request into a CAN signal to drive the DDCU / PDCU to perform hardware actions.

[0075] in,

[0076] Further, including:

[0077] The central interactive processing platform includes:

[0078] The user intention parsing unit is used to identify the user's identity and expected behavior based on the interaction triggering instructions; the scenario decision unit is used to generate a personalized interaction strategy based on the vehicle's current state and environmental information; and the multimodal fusion control unit is used to convert the interaction strategy into collaborative control instructions and coordinate the timing and intensity of visual, auditory, and tactile feedback.

[0079] Further, including:

[0080] The regional interaction execution unit also includes:

[0081] The service interface adaptation layer is used to convert the service instructions of the central interactive processing platform into a protocol format recognizable by the regional controller;

[0082] The regional controller cluster includes a body domain controller, a cockpit domain controller, and a power domain controller, which is used to execute the hardware control logic within the region;

[0083] The actuator driver layer is used to convert the instructions of the zone controller into hardware drive signals to control actuators such as the welcome light group, speakers, electric seats, and electric door mechanisms.

[0084] Furthermore, a car welcome mode interactive system also includes:

[0085] Scenario learning module, used to collect user interaction data and build user preference models;

[0086] An adaptive adjustment module is used to dynamically optimize the interaction strategy based on the user preference model, including parameters such as the brightness / color / timing of the welcome lighting effect, the content / volume / tone of the voice prompt, and the position / angle of the seat adjustment.

[0087] Further, including:

[0088] The FDD data interaction module also includes:

[0089] Service abstraction layer, used to abstract CAN / LIN bus signals into standardized service interfaces;

[0090] Protocol conversion layer, used to achieve bidirectional conversion between SOME / IP Ethernet protocol and CAN / LIN protocol;

[0091] The data routing layer is used to dynamically configure routing interaction data based on service ID and method ID, supporting service discovery and load balancing.

[0092] Specifically, FDD technology abstracts data from the sensor and actuator layers, converting complex raw data into a unified data format and interface. This allows upper-layer applications, regardless of their underlying structure, to access and manage this data through a unified interface, achieving data adaptation and unified management.

[0093] FDD can be considered a data adaptation layer, providing a unified data interface and format for upper-layer applications. Whether it's legacy ECUs (Electronic Control Units) or new smart sensors, they can all be uniformly managed and controlled using FDD technology, ensuring data compatibility and interoperability.

[0094] By adding FDD technology, even if the sensor and actuator data changes, the upper-layer application interface and software can remain unchanged. This means that automakers can replace and upgrade sensors and actuators at any time without affecting the vehicle's upper-layer applications, ensuring the stability and reliability of the vehicle system.

[0095] The FDD for legacy ECUs, collectively known as S2S FDD, primarily implements functions such as signal-to-service conversion, interface encapsulation, anomaly monitoring, local algorithm integration, specialized logic processing, and HMI prompts. These functions provide solid technical support for vehicle intelligence and offer drivers a more convenient and safe driving experience.

[0096] Conversion principles between Ethernet and CAN signals and services

[0097] 1. Extraction of signals and services

[0098] First, FDD technology receives raw signals from the Ethernet or CAN bus. These signals may contain various vehicle status and control information, such as vehicle speed, steering angle, and engine status. FDD technology extracts these raw signals and uses them as input data for subsequent processing.

[0099] 2. Data format conversion

[0100] Next, FDD technology converts the extracted raw signal into a uniform format. Ethernet and CAN communication protocols may have different data formats, and FDD technology must unify them to ensure accurate data transmission and processing.

[0101] 3. Mapping of signals and services

[0102] Once the data format is unified, FDD technology maps the original signal to the corresponding service. In automotive electronic systems, different functional modules typically correspond to different services, such as vehicle control, safety monitoring, and entertainment systems. FDD technology maps the signal to the corresponding service based on its meaning and purpose.

[0103] 4. Forwarding and Processing of Services

[0104] Finally, FDD technology forwards the converted services to the appropriate modules for processing. These modules may be located in different areas of the vehicle, such as the vehicle central computing center (VDC) or various regional control units (PDCF, PDCM, and PDCR). These modules perform corresponding control and operations based on the received services, thus achieving management and control of various vehicle functions.

[0105] FDD software implementation

[0106] On the software side, FDD technology requires the development of appropriate programs for signal extraction, format conversion, mapping, and forwarding. These programs typically run on the VDC (Very Central Data Center) or regional control units (PDCF, PDCM, PDCR). By analyzing and processing received data, they transform signals into services.

[0107] It is worth noting that although this system only discloses a trigger interaction module, an FDD data interaction module, a central interaction processing platform, a regional interaction execution unit and a multimodal interaction execution module, it does not mean that this device is limited to the above-mentioned basic functional modules. Rather, what the present invention wants to express is that, based on the above-mentioned basic functional modules, those skilled in the art can arbitrarily add one or more functional modules in combination with the existing technology to form an infinite number of embodiments or technical solutions. In other words, this system is open rather than closed. Just because this embodiment only discloses individual basic functional modules, it cannot be considered that the scope of protection of the claims of the present invention is limited to the above-mentioned basic functional modules.

[0109] like Figure 2 The methods shown include:

[0110] Acquire a user proximity signal according to a user proximity trigger unit, and generate an interaction trigger instruction according to the user proximity signal;

[0111] Abstract and encapsulate sensor and actuator data based on the FDD data interaction module, realize bidirectional conversion between Ethernet / CAN signals and services, and build a mapping link between interaction trigger commands and system responses;

[0112] The central interactive processing platform receives the interactive trigger instruction, calls the vehicle status data, and generates an interactive control instruction including sensory feedback;

[0113] converting the interactive control instruction into a hardware driving signal according to the regional interactive execution unit;

[0114] The multimodal interaction execution module executes the welcome lighting effect, voice prompt, and door / seat adjustment interaction actions according to the interaction control instructions.

[0116] Table 1

[0117] Refer to Table 1. The VDC (Vehicle Central Computing Platform): As the vehicle's central computing platform, the VDC receives data from each regional control unit, performs arbitration, and outputs control service instructions to each regional control unit. The VDC's core function is to integrate data from all vehicle subsystems and provide unified management and control.

[0118] Regional Control Units (PDCF+PDCM+PDCR): These three regional control units correspond to the control functions of the front, center, and rear zones, respectively. They receive control service commands from the VDC, convert them into network signals or hardwired outputs, and drive the sensors and actuators in each zone to implement the corresponding control functions.

[0119] FDD technology: data adaptation layer

[0120] To achieve unified management and control of sensor and actuator data, automakers are adopting FDD (Functional Design Document) technology. FDD abstracts and repackages the sensor and actuator data for the entire vehicle. It provides a unified interface and data format for upper-layer applications, ensuring that even when sensor and actuator data changes, the application software maintains the same interface and software. It primarily implements functions such as signal and service conversion, interface encapsulation, exception monitoring, integrated local algorithms, specialized logic processing, and HMI prompts.

[0121] The FDD receives control requests from the upper-layer VDC via Ethernet:

[0122] Key search logic path: The lock module sends a welcome request. The WDLCt (welcome system) receives the enter welcome request, activates welcome mode, and reports the actual status and exit reason. The WDLCt receives the exit welcome request and exits welcome mode.

[0123] BO_SA_FDD_WelLitCtrl Welcome light control FDD, by converting the control service of the welcome light control SWC to CAN signal and passing it to DDCU / PDCU, converts the control command and passes it to the headlight controller.

[0124] BO_SA_FDD_WelLitInfo Welcome light information FDD, converts the welcome light status CAN signal into a service and transmits it to the welcome light control SWC, and converts the signal into an Ethernet service and transmits it to the upper-layer VDC.

[0125] BO_VCt_ExtLitCtWelLitCtrl Welcome light control, provides and receives welcome light control related services to complete the welcome light function control.

[0128] A computer program is stored in the memory. When the computer program is executed by the processor, the processor executes the steps of a method for interactive control of a welcome mode of an automobile.

[0129] The present application also provides a computer-readable storage medium storing a computer program executable by an electronic device. When the computer program runs on the electronic device, the electronic device executes the steps of a method for interactive control of a car welcome mode.

Secondly, those skilled in the art should also be aware that the embodiments described in this specification are all preferred embodiments, and the actions involved are not necessarily required by the embodiments of the present invention.
