Vehicle Object Data Prioritization for Autonomous Driving Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional autonomous driving technologies transmit excessive data, including information of low importance, which can lead to communication abnormalities and inefficient data processing during driving assistance, as they lack a mechanism to prioritize and quantify the importance of collected information.
Innovation Solution
An information collection control device and method that analyzes detection information from sensors to identify objects, calculates the overlap of occupied areas before and after a set time interval, and determines transmission priority based on the calculated overlap, allowing for selective data transmission to the driving assistance control device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If all detected object information is transmitted to the driving assistance control device, then complete information is provided for autonomous driving assistance, but communication load increases and communication abnormalities occur
Solution Approach 1:
The patent extracts and transmits only the essential information elements (object ID, type, position, occupied area, time interval) needed for driving assistance, filtering out redundant data. This selective extraction maintains information completeness while reducing communication load and preventing communication abnormalities.
2Speed
If data transmission frequency is increased to provide real-time information, then information timeliness is improved, but communication load and data overload increase
Solution Approach 1:
The patent implements periodic action by transmitting information at specific time intervals rather than continuously. The autonomous driving control device determines appropriate time intervals for transmission, providing real-time information updates while controlling data volume and preventing communication overload.
3Measurement precision
If detection time interval is decreased to capture object movement, then measurement precision is improved, but data processing load increases
Solution Approach 1:
The patent applies dynamics by adaptively adjusting the detection time interval based on object characteristics and movement patterns. For moving objects, shorter intervals capture position changes accurately; for stationary objects, longer intervals reduce processing load. This dynamic adjustment maintains measurement precision while optimizing data processing efficiency.

AI summary
In an information collection control device for a vehicle capable of autonomous driving, configured to collect information about objects when the vehicle, during autonomous driving, receives driving assistance from a driving assistance control device, an identification unit analyses detection information detected by a sensor that monitors surroundings of the vehicle to identify a plurality of types of objects. An acquisition unit acquires, for each object identified by the identification unit, a location and an occupied area of the object. A time-interval setting unit sets a time interval for the acquisition unit acquiring the location and the occupied area. A score calculation unit calculates a size of an area of overlap between the occupied areas of the same object acquired before and after the set time interval. A priority determination unit determines a priority for transmission to the driving assistance control device based on the calculated size of the area of overlap.
