Vehicle Lane Change Control Adjusting Speed for Occupant Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lane change systems, such as adaptive cruise control (ACC), do not effectively manage lane changes to alleviate driver anxiety and ensure safety, as they fail to consider the characteristics and conditions of both the driver and passengers during automatic steering control.
Innovation Solution
A vehicle lane change control apparatus and method that includes a condition information acquisition unit, a lane change rate database, and a control unit to adjust lane change speed and steering based on driver and passenger conditions, using a lane change rate database to determine optimal entry steering angles and speeds for lane changes, and correcting these rates based on passenger distraction and emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If lane change is performed quickly to improve efficiency, then productivity increases, but driver anxiety and safety risks increase
Solution Approach 1:
The system dynamically adjusts the lane change rate based on real-time driver characteristics and passenger conditions. Instead of using a fixed lane change speed, the control unit modifies the lane change rate dynamically by selecting from multiple pre-stored rates or applying corrections to the basic rate, allowing the system to optimize between efficiency and safety for each specific situation.
Solution Approach 2:
The system changes the lane change rate parameter based on detected driver and passenger conditions. The control unit selects from multiple lane change rates stored in the database or corrects the basic lane change rate by increasing or decreasing it, thereby adjusting the lane change speed parameter to resolve the contradiction between fast lane changing and safety.
2Productivity
If lane change rate is increased to improve efficiency, then productivity increases, but driver frustration and anxiety increase
Solution Approach 1:
The system uses feedback from driver characteristics analysis and passenger condition detection to adjust the lane change rate. The control unit receives information about driver behavior patterns and passenger states, then selects or corrects the lane change rate accordingly, ensuring the lane change speed aligns with driver expectations and comfort levels.
Solution Approach 2:
The system adjusts the lane change rate parameter based on feedback about driver characteristics and passenger conditions. By storing multiple lane change rates and selecting or correcting the basic rate according to detected conditions, the system optimizes the lane change speed parameter to balance efficiency with driver comfort and reduce frustration.
3Ease of operation
If lane change control considers only driver characteristics, then ease of operation improves, but reliability decreases due to passenger safety risks
Solution Approach 1:
The system serves multiple functions simultaneously: it analyzes driver characteristics to determine preferred lane change patterns while also detecting passenger conditions to ensure safety. The condition information acquisition unit and control unit work together to make lane change rate decisions that consider both driver comfort and passenger safety, making the system universally applicable to protect all occupants.
Solution Approach 2:
The control unit acts as an intermediary between driver preferences and passenger safety requirements. It receives input about driver characteristics and passenger conditions, then mediates the lane change rate selection by choosing or correcting the basic rate to satisfy both driver comfort expectations and passenger safety concerns.

AI summary
A vehicle lane change control apparatus includes a condition information acquisition unit that acquires condition information of an occupant of a vehicle, a lane change rate database unit that stores a lane change rate that is determined based on a lane change pattern of a driver analyzed based on driving information when a lane of the vehicle is changed and road condition information when the lane of the vehicle is changed and indicates a speed of the lane change, and a control unit that changes the lane of the vehicle through steering control according to operation information of the vehicle, and based on the condition information of the occupant acquired by the condition information acquisition unit, controls the lane change of the vehicle by selectively using the lane change rate and a corrected lane change rate determined by increasing or decreasing the lane change rate.
