Vehicle Surroundings Data Integration via Roadside Sensors
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for gathering information about a vehicle's surroundings, such as using sensors mounted on the vehicle, are prone to reliability issues due to environmental factors like sunlight and obstacles, leading to incomplete or inaccurate data, especially when sensors are obstructed or covered.
Innovation Solution
An apparatus that integrates information from vehicle-mounted sensors, roadside communication devices, and central communication devices, using data gathering blocks to classify and manage data based on predefined reliability criteria, ensuring accurate and comprehensive information gathering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sensors mounted on the vehicle are used to gather information about the surroundings, then the system can obtain real-time data, but the reliability of the gathered information degrades due to environmental factors such as sunlight and obstacles
Solution Approach 1:
The patent introduces roadside communication devices and central communication devices as intermediary elements between the vehicle sensors and the information processing system. These intermediaries provide alternative information channels that are not affected by environmental factors blocking vehicle-mounted sensors, such as traffic lights blocked by tall vehicles or sensors covered by foreign matter.
Solution Approach 2:
The patent merges multiple information gathering channels: vehicle sensor data, roadside equipment data, and central communication data. By combining these diverse data sources, the system compensates for the limitations of individual sensors and achieves more reliable surrounding information through data fusion and integration.
2Loss of information
If only vehicle-mounted sensors are used, then the system structure remains simple, but the comprehensiveness of information gathering is insufficient when sensors are obstructed
Solution Approach 1:
The patent segments the information gathering function into multiple independent components: vehicle sensor data gathering block, roadside equipment data gathering block, and central communication data gathering block. Each block operates independently to collect information from different sources, reducing the risk that a single point of failure will result in complete information loss.
Solution Approach 2:
The patent creates a multi-functional information gathering system where roadside communication devices and central communication devices serve multiple purposes: they can provide traffic light information, road information, distance information to surrounding vehicles, and other surrounding environment data, making the system more comprehensive without proportionally increasing complexity.

AI summary
An apparatus for gathering information about surroundings of a vehicle includes: a vehicle sensor data gathering block configured to gather first information about surroundings of the vehicle from one or more sensors mounted on the vehicle; a roadside equipment data gathering block configured to gather second information about surroundings of the vehicle from a roadside communication device installed on a driving infrastructure; and a data integration block configured to classify the first information about surroundings and the second information about surroundings for predefined data types and integrate and manage the classified information about surroundings based on a preset reliability criterion.
