Vehicle Control Device Lateral Interval Adjustment for Pedestrian Safety
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems do not adequately consider the behavior of pedestrians in relation to surrounding situations, leading to inadequate driving control, especially in scenarios involving overtaking and recognition of structures like side gutters.
Innovation Solution
A vehicle control system that includes a recognition unit to identify surrounding situations and a driving control unit to adjust the vehicle's position and speed based on the recognition of pedestrians and structures, increasing the distance from pedestrians when overtaking and changing lanes to avoid potential collisions with side gutters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the vehicle maintains a standard minimum interval when overtaking pedestrians, then the productivity is improved, but the reliability deteriorates due to potential collision with side gutters
Solution Approach 1:
The vehicle control device dynamically adjusts the lateral interval between the vehicle and pedestrian based on the recognized position of side gutters. When a side gutter is detected near the pedestrian, the system automatically increases the lateral interval beyond the standard minimum, preventing the pedestrian from falling into the gutter while maintaining efficient overtaking when no such hazard is present.
Solution Approach 2:
The side gutter recognition acts as an intermediary factor that mediates between the vehicle and pedestrian. By detecting the presence and position of side gutters, the system uses this environmental information to adjust the lateral interval, creating a safety buffer that prevents accidental contact with the gutter while allowing normal overtaking behavior when the gutter is not present.
2Reliability
If the vehicle increases lateral interval when side gutter is recognized, then the reliability is improved, but the productivity deteriorates due to reduced overtaking efficiency
Solution Approach 1:
The system dynamically adjusts the lateral interval based on the presence of side gutters. When a side gutter is recognized, the lateral interval is increased to prevent the pedestrian from falling into it. When no side gutter is present, the system returns to using the standard minimum lateral interval, thereby maintaining overtaking efficiency. This dynamic adjustment resolves the contradiction by applying the increased interval only when necessary.
Solution Approach 2:
The increased lateral interval is applied locally and selectively only in the specific situation where a side gutter is recognized near the pedestrian. In all other situations, the standard minimum lateral interval is maintained. This localized application of the safety measure ensures that productivity is not degraded in situations where the hazard does not exist.
3Device complexity
If the vehicle uses basic pedestrian detection, then the device complexity is reduced, but the measurement precision deteriorates regarding pedestrian behavior prediction
Solution Approach 1:
The system performs preliminary recognition of side gutters and their positions before the overtaking maneuver is executed. By advance 识别 of the environmental hazard, the system can pre-calculate the appropriate lateral interval adjustment, improving the precision of pedestrian behavior prediction without requiring complex real-time analysis during the overtaking action itself.
Solution Approach 2:
The side gutter recognition serves as an intermediary that provides additional contextual information about the environment. This environmental marker helps the system predict pedestrian behavior more accurately by indicating potential hazards that may influence the pedestrian's movements, thereby improving measurement precision without significantly increasing device complexity.

AI summary
A vehicle control device includes a recognition unit which recognizes surrounding situations of a vehicle, and a driving control unit which automatically controls at least steering of the vehicle based on the surrounding situations recognized by the recognition unit, and the driving control unit increases a distance between the vehicle and a traffic participant in the case where the recognition unit recognizes the traffic participant as an overtaking target and a predetermined structure in a traveling direction of the vehicle, and the vehicle travels on a side opposite to the predetermined structure in a road width direction in a case that viewed from the traffic participant to overtake the traffic participant, as compared to a case where the traffic participant as the overtaking target is recognized by the recognition unit in the traveling direction of the vehicle and the predetermined structure is not recognized.
