[0091] In the above embodiment, the core of the power door system is the door controller (DCM).

[0114] Special logic processing: Perform special logic processing on specific situations to meet the personalized needs of the system.

[0115] HMI prompts: Provide human-machine interaction interface prompts to facilitate user operation and understanding of system status.

[0116] FDD technology: data adaptation layer

[0117] 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.

[0118] In terms of software, FDD technology requires the development of corresponding programs for signal extraction, format conversion, mapping, and forwarding. These programs usually run on the central computing platform (VDC) or regional control units (PDCF, PDCM, PDCR), and realize the conversion function of signals and services by analyzing and processing the received data. Figure 2 As shown:

[0119] FDD receives the upper layer's control request for the electric door through Ethernet, BO_SA_FDD_ElectricDoorCtrl, and the electric door control FDD converts the electric door control SWC's control service for the car door into a CAN signal and transmits it to the DDCU / PDCU / RLDCU / RRDCU;

[0120] BO_SA_FDD_ElectricDoorInfo, electric door information FDD, converts the electric door status CAN signal into service delivery electric door control SWC;

[0121] BO_VCt_ElectricDoorControl, electric door control, provides and receives electric door control related services to complete electric door function control.

[0122] The components are described in the following table:

[0123]

[0124] Functional Design Document (FDD) technology plays a key role in automotive electronics systems. It abstracts and repackages data from the vehicle's sensor and actuator layers, enabling unified data management and control. Let's take a deeper look at the working principles and functions of FDD technology.

[0125] FDD technology abstracts sensor and actuator layer data, converting complex raw data into a unified data format and interface. This allows upper-layer applications to access and manage this data through a unified interface, achieving data adaptation and unified management.

[0126] 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.

[0127] In the above-mentioned embodiments, 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.

[0128] FDD Specific Functions: The FDD for legacy ECUs is collectively referred to as S2S FDD. It 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.

[0129] In one embodiment, the conversion principle between Ethernet and CAN signals and services is described in detail:

[0130] 1. Extraction of signals and services

[0131] 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.

[0132] 2. Data format conversion

[0133] 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.

[0134] 3. Mapping of signals and services

[0135] 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.

[0136] 4. Forwarding and Processing of Services

[0137] 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.

[0138] In one embodiment, the electric door control process of an FDD-based automobile electric door control system disclosed in the above embodiment may include: the user issues an electric door opening or closing instruction through a touch screen or voice recognition; the instruction is transmitted to the central computing platform VDC through Ethernet or CAN bus; the central computing platform VDC arbitrates and judges the received instruction, determines the control strategy of the electric door, and generates a control instruction; the VDC sends the control instruction to the corresponding regional control unit, converts the control instruction into a network signal or hard-wired output, and drives the sensors and actuators in each area to perform the electric door opening or closing operation; the door controller DCM feeds back the status information of the electric door in real time, and transmits it to the central computing platform VDC through the LIN bus or CAN bus; the VDC displays the status information of the electric door to the user through the human-computer interaction interface.

[0139] In the above embodiment, the system can also store the control instructions and status information of the electric door to facilitate subsequent analysis and optimization.
