Lane Change Control Using Timed Driver Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing autonomous driving systems lack a robust control strategy to ensure the safety of both the vehicle performing a lane change and surrounding vehicles, particularly in managing the timing and execution of lane changes.
Innovation Solution
The system employs a control circuit that initializes a lane change progress rate upon driver input, adjusts speed based on elapsed time and proximity to the target lane, and cancels the lane change if not completed within specified intervals, while providing warnings to the driver to maintain safety.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lane change execution is delayed to ensure safety monitoring, then the safety of surrounding vehicles is improved, but the productivity of the lane change operation deteriorates
Solution Approach 1:
The system performs preliminary safety monitoring and environmental assessment before executing the lane change. The control circuit receives driver input and initiates a monitoring period to detect surrounding vehicles and assess safety conditions before the actual lane change maneuver begins, ensuring safety is verified in advance.
Solution Approach 2:
The system dynamically adjusts the lane change execution based on real-time safety conditions. The control circuit monitors the progress rate and can adjust the speed of lane change execution or cancel the maneuver if safety conditions change during the process, making the system adaptable to dynamic environmental conditions.
2Reliability
If the lane change progress is monitored continuously, then the reliability of the operation is improved, but the device complexity increases
Solution Approach 1:
The control circuit continuously monitors the progress rate of the lane change operation and uses this feedback to adjust control signals to the steering actuator. The system receives progress information, compares it with target parameters, and dynamically adjusts the lane change execution to maintain safety and achieve the desired maneuver.
3Productivity
If the lane change speed is increased to improve productivity, then the productivity is improved, but the safety of surrounding vehicles deteriorates
Solution Approach 1:
The system dynamically adjusts the lane change execution speed based on real-time safety assessments. The control circuit can accelerate the lane change when safety conditions permit, improving productivity, while automatically reducing speed or canceling the maneuver when surrounding vehicles are detected, eliminating harmful effects to other road users.

AI summary
An apparatus for controlling driving in a vehicle is provided. The apparatus includes one or more input devices configured to receive an input from a driver of the vehicle and a control circuit electrically connected with the one or more input devices. The control circuit is configured to activate a lane change when a first input for the lane change is received via the one or more input devices, initiate a lateral movement for the lane change when a second input for the lane change is received via the one or more input devices within a first time interval after the first input, and cancel the lane change when the second input is not received within the first time interval after the first input.
