Autonomous Lane Change Control for High-Speed Vehicle Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems do not account for the possibility of a high-speed approaching vehicle when determining lane changes in low-congestion zones, which can lead to sudden entry into the host vehicle's planned lane change zone.
Innovation Solution
A driving control method and device that determines whether another vehicle is within a detection zone of the planned lane change, allowing autonomous lane changes only when it is unlikely for a trailing vehicle to enter at a higher speed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous lane change control is enabled in low-congestion zones, then lane change efficiency is improved, but safety is worsened due to undetected high-speed approaching vehicles
Solution Approach 1:
The system performs preliminary detection of approaching vehicles in the target lane before executing the lane change maneuver. By using radar or camera sensors to identify vehicles in the detection zone ahead of the lane change, the system proactively assesses potential risks and determines whether conditions are safe for autonomous lane changing, thereby preventing collisions with high-speed approaching vehicles.
2Reliability
If the detection zone is expanded to improve safety, then device complexity is improved, but measurement precision is worsened due to increased detection range challenges
Solution Approach 1:
The system implements a detection zone with spatially varying detection characteristics. The detection sensitivity and resource allocation are concentrated in the critical region where approaching vehicles pose the greatest risk to lane change safety, rather than uniformly across all directions. This allows the system to maintain high detection precision for safety-critical areas while managing overall system complexity.

AI summary
A driving control method is performed to execute a lane-change control for controlling a host vehicle to autonomously change lanes from a first lane to an adjacent second lane using a processor of a driving control device that controls vehicle speed and steering of the host vehicle traveling in the first lane in an autonomous driving mode. The processor determines that the lane-change control can be executed upon determining that the other vehicle has been detected in a detection zone of the second lane, based on a detection result of a sensor. The processor determines that the lane-change control cannot be executed upon determining that the other has not been detected within the detection zone of the second lane. The processor outputs information regarding whether the lane-change control can be executed.
