Sensor Data Reporting Periods for Efficient Autonomous Driving Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In automatic driving systems, the differing update periods of data from various sensors lead to the transmission of redundant information, resulting in low utilization of transmission resources.
Innovation Solution
A communication method where first data and second data are sent to a second apparatus based on distinct sending periods, with the periods being preconfigured or determined based on the data collection periods, thereby reducing redundant information transmission.

Engineering Contradiction Analysis
1Ease of manufacture
If data from sensors are reported in a unified manner based on a single report period, then data fusion can be completed based on standardized interface, but a large amount of redundant information is caused and transmission resource utilization is low
Solution Approach 1:
The patent segments the unified data transmission process into multiple independent transmission channels, each with its own report period. Different sensor data types (first data and second data) are transmitted separately based on their respective periods, allowing customization of transmission frequency for each data type while maintaining standardized interfaces at the fusion layer.
Solution Approach 2:
The patent implements dynamic report periods for different data types. The first data uses a first report period while the second data uses a second report period, allowing the system to adapt transmission frequency to the actual update rates of different sensors, thereby reducing redundant transmissions without compromising data fusion capability.
2Ease of operation
If a single report period is used for all sensor data, then transmission scheduling is simplified, but redundant information transmission increases and resource utilization decreases
Solution Approach 1:
The transmission scheduling is segmented into multiple independent periodic tasks, each handling a specific data type with its own report period. This segmentation allows each transmission task to operate independently with optimized timing, improving resource utilization while maintaining operational simplicity through standardized scheduling interfaces.
Solution Approach 2:
The patent changes the time parameter (report period) for different data types. By setting different report periods for first data and second data based on their collection periods, the system optimizes transmission frequency to match actual data generation rates, thereby improving resource utilization without complicating the scheduling mechanism.
3Loss of information
If data transmission follows sensor collection periods, then redundant information is reduced, but transmission scheduling complexity increases
Solution Approach 1:
The patent implements dynamic transmission scheduling where the report period for each data type is determined by its collection period. This dynamic adaptation allows the system to automatically adjust transmission frequency to match sensor update rates, reducing redundant information while maintaining manageable scheduling complexity through rule-based period determination.
