Lane Change Recommendation via Speed Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional driving assistance technologies require drivers to determine the appropriate traffic lane for lane changes, which is insufficient as they only consider the state of their own lane and adjacent lane, lacking comprehensive analysis.
Innovation Solution
A driving assistance apparatus that determines the recommended travel lane by comparing the preset vehicle speed with the travel states of preceding and adjacent vehicles, allowing the system to autonomously decide lane changes based on relative speeds and available lane conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driver determines the traffic lane manually, then the driver has full control over lane selection, but the determination process becomes complex and time-consuming for the driver
Solution Approach 1:
The system enables automatic lane determination by having the determination unit autonomously select the recommended lane based on vehicle states and traffic conditions, eliminating the need for manual driver intervention in lane selection decisions
Solution Approach 2:
The determination unit acts as an intermediary between the complex traffic environment and the driver, processing multiple vehicle state parameters and traffic conditions to provide a simplified lane recommendation that the driver can easily accept or reject
2Measurement precision
If the system only considers own lane and adjacent lane states, then the system simplicity is maintained, but the lane determination accuracy is insufficient
Solution Approach 1:
The system segments the traffic environment into distinct analysis units (own vehicle state, preceding vehicle state, adjacent vehicle state, lane state) that are processed separately by the determination unit, allowing comprehensive analysis while maintaining system manageability
Solution Approach 2:
The system expands the analysis from two-dimensional (own lane and adjacent lane) to three-dimensional by incorporating longitudinal position information and vehicle speed dimensions, enabling more accurate lane determination through comparison of preset speed with actual vehicle speeds
3Measurement precision
If the system performs comprehensive traffic lane determination automatically, then the lane selection accuracy improves, but the processing time and computational load increase
Solution Approach 1:
The system performs preliminary data collection and preprocessing of vehicle state parameters and traffic conditions continuously, so that when lane determination is needed, the determination unit can quickly process pre-organized information without extensive real-time computation
Solution Approach 2:
The determination unit dynamically adjusts the weight and importance of different parameters (vehicle speed, position, lane state) based on current traffic conditions, allowing efficient decision-making by focusing on the most relevant parameters rather than processing all parameters equally

AI summary
A driving assistance apparatus is mounted in an own vehicle and performs driving assistance for the own vehicle. The driving assistance apparatus determines a travel recommended lane in which the own vehicle is to travel, based on a comparison of a preset vehicle speed set in advance to allow the own vehicle to travel at a constant speed, to a travel state of a preceding vehicle traveling ahead of the own vehicle in a travel lane in which the own vehicle is traveling and a travel state of an adjacent vehicle traveling ahead of the own vehicle in an adjacent lane that is adjacent to the travel lane. The driving assistance apparatus performs output based on the travel recommended lane.
