Controller-Mediated Sensor Data Transmission Across Incompatible Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In intelligent vehicles, controllers may not be able to obtain data from sensors due to incompatible data interfaces and protocols, leading to redundant sensor configurations and increased hardware complexity.
Innovation Solution
A first controller supports a data interface for a sensor and converts data to a compatible protocol for a second controller that does not support the interface, allowing data transmission between controllers using a common communication protocol.

Engineering Contradiction Analysis
1Adaptability or versatility
If a data interface of a sensor is incompatible with multiple controllers, then each controller cannot obtain sensor data, but adding more sensors to support each controller increases hardware complexity and cost
Solution Approach 1:
The first controller acts as an intermediary between the sensor and the second controller. It receives data from the sensor through its compatible data interface, converts the data according to a target communication protocol, and forwards it to the second controller. This mediator approach allows the second controller to access sensor data without needing direct interface compatibility, thereby reducing hardware complexity while maintaining adaptability.
Solution Approach 2:
The first controller performs multiple functions: it serves as both a data collector from the sensor and a protocol converter for the second controller. By making the first controller universal (handling both sensor communication and inter-controller data transmission), the system avoids the need for each controller to have dedicated sensor interfaces, thus reducing overall hardware complexity while maintaining versatility.
2Adaptability or versatility
If protocol conversion is implemented at the controller level, then data sharing between controllers is enabled, but processing complexity increases
Solution Approach 1:
The first controller serves as a protocol conversion intermediary. It receives data in the sensor's native format, converts it to a target communication protocol understood by the second controller, and transmits it. This centralized conversion approach enables data sharing between controllers with different protocols while concentrating the conversion complexity in a single device rather than distributing it across multiple controllers.

AI summary
This application provides a data transmission method, apparatus, and a system. The data transmission method includes: A first controller receives a data obtaining request from a second controller, where the data obtaining request requests to obtain data of a first sensor, the first controller supports a data interface corresponding to the first sensor, and the second controller does not support the data interface corresponding to the first sensor; the first controller receives first data from the first sensor; and the first controller sends converted first data to the second controller according to a first communication protocol. In this way, a second electronic apparatus can obtain data from the first sensor from a first electronic apparatus. This helps avoid redundant sensor configuration.
