Innovation Solution
A vehicle control apparatus that includes a detecting unit to identify nearby vehicles, an estimating unit to predict their positional changes, and a period deriving unit to determine the lane changeable period, allowing for the narrowing down of lane change target positions based on derived periods, and generating a control plan for safe and efficient lane changes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the existing vehicle control system only determines whether to change lanes based on collision risk, then the determination process is simple, but smooth lane change control cannot be performed
Solution Approach 1:
The system performs preliminary estimation of nearby vehicle positional changes and derives the lane changeable period before making the lane change determination. This advance preparation of temporal window information enables smoother lane change execution while maintaining a structured determination process.
2Reliability
If the system sets a lane change target position without considering the lane changeable period, then the control plan can be generated quickly, but the control plan may be unrealistic
Solution Approach 1:
The system preliminarily estimates the positional changes of nearby vehicles and derives the lane changeable period before generating the control plan. This ensures that the target position selection is based on realistic temporal windows, improving control plan realism without excessive time loss.
Solution Approach 2:
The system dynamically adjusts the lane change target position selection based on the derived lane changeable period. The narrowing unit adapts the target position candidates according to the temporal constraints, ensuring realistic control plans while maintaining efficient processing.
3Manufacturing precision
If the system narrows down lane change target positions based on the lane changeable period, then the lane change precision is improved, but additional processing steps are required
Solution Approach 1:
The narrowing unit dynamically filters lane change target position candidates based on the derived lane changeable period. This dynamic filtering process improves position precision by eliminating unrealistic targets while adding only necessary processing steps.

AI summary
A vehicle control apparatus includes a detecting unit configured to detect a nearby vehicle that travels near a host vehicle; an estimating unit configured to estimate a positional change of the nearby vehicle detected by the detecting unit; and a period deriving unit configured to derive a lane changeable period during which lane change is possible to a lane change target position set as a relative position with respect to the nearby vehicle that travels in an adjacent lane that is adjacent to a host vehicle lane on the basis of a positional change of the nearby vehicle estimated by the estimating unit.
