Vehicle Lateral Control Using Validated Swarm Environment Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lateral guidance systems rely heavily on sensor data, which can be unreliable due to sensor failures, dirt, or environmental conditions, leading to potential inaccuracies in environmental data acquisition.
Innovation Solution
Integrate swarm data from a fleet of vehicles that have previously traveled the same route, validating this data against the vehicle's own sensor data to ensure accuracy and reliability for lateral guidance, switching to own data if significant discrepancies are detected.

Engineering Contradiction Analysis
1Reliability
If lane keeping assist systems use only own-vehicle sensors, then system independence is maintained, but detection reliability in occluded areas deteriorates
Solution Approach 1:
The patent introduces V2V communication as an intermediary mechanism that enables information exchange between vehicles. The own-vehicle sensor system receives lane marking detection results from neighboring vehicles through V2V communication, effectively extending detection coverage to occluded areas without requiring additional physical sensors on the own vehicle.
Solution Approach 2:
The patent makes the lane marking detection system universal by enabling vehicles to share detection results through V2V communication. A single vehicle's sensor system can detect lane markings for multiple vehicles by sharing detection data, allowing the system to serve multiple functions beyond just the own vehicle's immediate sensor range.

If lane marking detection relies on own-vehicle sensors only, then system simplicity is maintained, but detection coverage in occluded areas deteriorates
Solution Approach 1:
V2V communication acts as an intermediary that transfers detection information from neighboring vehicles to the own vehicle. This enables the own-vehicle system to access detection data from areas that would otherwise be occluded or beyond the own vehicle's sensor range, effectively expanding detection coverage without adding physical sensors.
Solution Approach 2:
The patent uses copying by receiving and utilizing lane marking detection results from neighboring vehicles as if they were detected by the own vehicle's sensors. The detection information is copied from other vehicles' sensor systems and processed by the own vehicle's control system, extending coverage without duplicating physical sensing infrastructure.
3Reliability
If environmental data is shared between vehicles, then detection reliability in occluded areas improves, but data security and privacy protection requirements increase
Solution Approach 1:
The patent extracts only the necessary environmental data (lane marking detection results) for sharing between vehicles, rather than transmitting all sensor data. This selective extraction minimizes the amount of data exposed to security risks while maintaining the reliability benefits of shared environmental information.
