Longitudinal Guidance Target Selection During Aborted Lane Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for target object selection in longitudinal guidance systems fail to address the issue of unnecessary control actions on aborted or interrupted lane change processes, potentially violating comfort or safety distances.
Innovation Solution
An assessment device determines the likelihood of the vehicle returning to the original driving lane after an aborted lane change, allowing for prompt adjustment of the target object selection to either maintain the new or revert to the original target object based on system and environmental factors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the target object is changed to a target object along the target driving lane during a lane change process, then the longitudinal guidance system can adapt to the new lane, but if the lane change is aborted, the control action is applied for an unnecessarily long time to target objects along the target driving lane, potentially violating comfort or safety distances
Solution Approach 1:
The system continuously monitors the completion status of lane change processes and uses this feedback to dynamically adjust target object selection. When a lane change is aborted, the system detects this state and switches back to the original target object, ensuring continuous and reliable safety distance maintenance without unnecessary control actions.
Solution Approach 2:
The target object selection is made dynamic rather than static. The system adapts the target object based on the actual lane change execution status - using the target lane object during successful lane changes and reverting to the original lane object when lane changes are aborted, thereby maintaining reliability across different operational scenarios.
2Speed
If the target object is changed during an aborted lane change process, then the system responds to the lane change initiation, but the target object selection is delayed, causing unnecessary control actions
Solution Approach 1:
The system prepares by establishing the original target object before lane change initiation. When the lane change is aborted, this pre-established target object can be immediately reselected without delay, eliminating unnecessary control actions and reducing the time loss associated with target object switching.
3Ease of operation
If the system maintains control actions on target objects along the target driving lane after aborted lane change, then the lane change initiation is acknowledged, but comfort distances or safety distances may be violated
Solution Approach 1:
The system uses feedback from the lane change completion status to determine appropriate target object selection. By monitoring whether the lane change was successfully completed or aborted, the system adjusts its control actions accordingly, eliminating distance violation risks while maintaining ease of operation for initiated lane changes.

AI summary
Technologies and techniques for selecting a target object for a longitudinal guidance system of a motor vehicle. A method includes adapting a driving parameter of the motor vehicle based on the target object. Initially, the motor vehicle is operated along a designated driving lane, adjusting the driving parameter in response to a first target object traveling ahead in the same lane. Additionally, a semi-automated lane change is initiated, transitioning the vehicle from the initial driving lane to an adjacent target driving lane and shifting focus from the first to a second target object in the new lane. If this lane change process is interrupted or aborted, the method assesses the likelihood that the vehicle will revert to the original driving lane. Depending on this likelihood, the control system either maintains the second target object, reselects the first target object, or discontinues target object selection for the continuation of the journey.
