Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle control systems cannot predict the behavior of moving objects in blind spots, leading to sudden changes in vehicle behavior that cause occupant discomfort due to the inability to detect stationary objects obstructing the view of moving vehicles.
Innovation Solution
A driving assistance device that uses object detection sensors, position estimation, and map acquisition to predict the actions of parallel-traveling vehicles, incorporating blind spot area detection and action probability correction to generate a safe route for the host vehicle, thereby avoiding sudden changes in behavior.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the vehicle control device uses object detection sensors to detect objects around the host vehicle, then the detection capability is improved, but the stationary objects in blind spot areas cannot be detected due to obstruction by moving objects
Solution Approach 1:
The patent introduces a blind spot area generation determination unit that acts as an intermediary to identify regions where stationary objects may exist but are obscured by moving objects. By using the position and movement information of moving objects as a mediator, the system infers the presence of stationary objects in blind spot areas without directly detecting them, thus resolving the information loss problem.
Solution Approach 2:
The system performs preliminary action by proactively identifying blind spot areas and predicting potential stationary objects before they become actual collision risks. The blind spot area generation determination unit continuously monitors and pre-identifies regions where detection is compromised, allowing the vehicle to take preventive measures rather than reacting to detected objects alone.
2Reliability
If the vehicle control device immediately changes vehicle behavior when a moving object causing a blind spot area suddenly changes its behavior, then collision avoidance is improved, but the occupant feels uncomfortable due to sudden behavior change
Solution Approach 1:
The system applies preliminary action by predicting the future behavior of moving objects causing blind spots based on their current trajectory and characteristics. When a potential risk is foreseen, the vehicle gradually adjusts its route in advance rather than making sudden changes, thus maintaining both collision avoidance reliability and occupant comfort through smooth transitions.
Solution Approach 2:
The patent implements dynamics by making the vehicle's route adjustment flexible and adaptive. Instead of fixed immediate responses, the vehicle dynamically modifies its trajectory based on predicted moving object behavior, allowing smooth, progressive adjustments that maintain safety while ensuring occupant comfort through non-abrupt movements.

AI summary
A driving assistance method detects a behavior of a moving object (52) causing a blind spot area (54) around a host vehicle (51), predicts a probability of action that the moving object (52) takes when an obstacle (53) is present in the blind spot area (54), according to a road structure around the host vehicle (51), and compares the behavior of the moving object (52) with the probability of action that the moving object (52) takes, so as to predict an action of the moving object (52).
