Vehicle Perception Sharing for Safer Lane-Change Decisions
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drivers frequently change lanes during peak hours based on perceived faster traffic in adjacent lanes, leading to increased accident risk and frustration, as actual lane conditions often differ from perceived conditions.
Innovation Solution
An autonomous vehicle equipped with a perception system and wireless communication equipment broadcasts a network identifier, allowing other vehicles to connect and receive personalized traffic condition information via sensors, generating and transmitting customized traffic updates through a Wi-Fi hotspot or network system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If drivers frequently change lanes based on perceived faster traffic, then drivers may achieve higher speed, but accident risk and driver frustration increase
Solution Approach 1:
The system provides real-time feedback to drivers about actual traffic conditions in adjacent lanes through wireless communication, replacing subjective perception with objective data. This feedback loop allows drivers to make informed lane change decisions based on accurate traffic flow information, reducing unnecessary lane changes and improving driving safety while maintaining speed optimization.
Solution Approach 2:
The patent introduces an intermediary system (wireless communication equipment and perception system) that mediates between the driver's perception and actual traffic conditions. This intermediary provides personalized traffic condition information about vehicles in adjacent lanes, acting as a bridge that transforms subjective lane change decisions into objective, data-driven decisions, thereby reducing accidents and frustration.
2Ease of operation
If drivers rely on perceived traffic conditions, then lane change decisions are simple, but accuracy of traffic information is poor
Solution Approach 1:
The system replaces the mechanical/sensory process of human perception (visual estimation, intuition) with an electronic information system. The perception system captures actual traffic data, and wireless communication transmits this data to drivers, substituting subjective sensory judgment with objective measured information, thereby improving traffic condition accuracy while maintaining ease of access through simple wireless communication interfaces.

AI summary
A vehicle includes a vehicle wireless communication equipment, a perception system including a plurality of sensors, an indicium for connecting to the vehicle wireless communication equipment. The wireless communication equipment is configured to establish a session with a third-party client device and receive a request from the third-party client device to receive personalized or custom traffic condition information based upon a specific position identified of a second vehicle associated with the third-party client device. At least one processor of the perception system is configured to generate the personalized or custom traffic condition information corresponding to the specific position of the second vehicle based upon sensor data of the plurality of sensors of the perception system, and initiate transmission of the personalized or custom traffic condition information corresponding the specific position of the second vehicle to the third-party client device via the vehicle wireless communication equipment over the established session.
