Abstract
Description
Technical Field
[0001] This disclosure relates to the field of vehicle communication technology, and in particular to a method, apparatus, electronic device, and storage medium for converting signals and service messages. Background Technology
[0002] In autonomous driving systems, signals serve as inputs and can be digital representations of physical quantities directly acquired by hardware sensors, such as point cloud data generated by LiDAR and pixel arrays of images captured by cameras. These signals typically exist in binary or numerical array form. As outputs, signals can represent physical layer control parameters for the drive actuators, transformed from logical decisions output by higher-level functional modules (such as planning and control modules). Service information, on the other hand, is a standardized data unit encapsulating the decision results of higher-level functional modules, carrying concrete operational instructions.
[0003] It is necessary to transform the raw signals at the bottom layer into service information because the raw signals themselves do not have driving decision-making value. They must be processed to transform the raw signals into service information containing environmental semantics so that higher-level functional modules can understand the current road conditions and formulate reasonable driving strategies. If the system remains at the signal level, it cannot form an understanding of the environment, and the decision-making process cannot be carried out.
[0004] Conversely, converting service information into underlying control signals is equally crucial. This is because the decision-making instructions contained in the service information belong to the logical functional requirements and cannot be directly recognized and executed by the hardware. A signal conversion process is necessary to transform these decision-making instructions into specific control signals that the hardware can interpret, enabling the hardware to accurately execute the corresponding actions and translating service-level decisions into actual driving operations.
[0005] Therefore, the mutual conversion between signals and service information is the key to achieving a complete closed loop of perception, decision-making, and execution in autonomous driving systems. The conversion of signals into service information completes the leap from raw data to environmental cognition and decision-making, providing a logical basis for driving behavior; the conversion of service information into signals realizes the implementation from decision commands to hardware actions, ensuring the effective execution of driving strategies.
[0006] Therefore, a method for converting service information and signals is needed to support the stable operation of autonomous driving systems from environmental perception to safe driving. Summary of the Invention

The target turn code is used to convert service information of the type of the service into a signal. The service message conversion module is used to convert the vehicle control service message into a target signal based on the target turn code.

The method according to claim 1, characterized in that, After converting the vehicle control service message into a target signal based on the target turn code, the method further includes: The target signal is sent to the vehicle communication bus so that the corresponding electronic control unit receives the target signal from the vehicle communication bus and performs vehicle control based on the target signal.
8. A signal-to-service message conversion device, characterized in that, include: A raw signal receiving module is used to receive at least one raw signal, each of the at least one raw signal carrying a first signal type; The target conversion code invocation module is used to invoke the target conversion code corresponding to the first signal type, and the target conversion code is used to convert the signal of the first signal type into service information. A signal conversion module is used to convert each of the at least one original signal into a target service message based on the target conversion code. The target service message sending module is used to send the target service message to the corresponding subscriber, so that the subscriber generates a vehicle control service message based on the target service message and sends the vehicle control service message, wherein the vehicle control service message carries the service type. The target turn code module is used to receive the vehicle control service message and call the target turn code corresponding to the service type. The target turn code is used to convert service information of the type of the service into a signal. The service message conversion module is used to convert the vehicle control service message into a target signal based on the target turn code.
9. An electronic device, characterized in that, include: processor; Memory used to store the processor's executable instructions; The processor is configured to execute the instructions to implement the signal and service message conversion method as described in any one of claims 1 to 7.
10. A computer-readable storage medium, characterized in that, When the instructions in the storage medium are executed by the processor of the electronic device, the electronic device is able to perform the signal and service message conversion method as described in any one of claims 1 to 7.
