Vehicle Control Apparatus Pedestrian Crossing Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle control systems perform unnecessary driving controls when pedestrians are detected in dividing strips or similar areas, as they assume pedestrians do not cross beyond barriers, leading to inappropriate avoidance maneuvers.
Innovation Solution
A vehicle control apparatus and method that includes a pedestrian recognition unit, a space recognition unit, and a driving control unit to assess the behavior of pedestrians and vehicles, determining if a pedestrian is moving from an oncoming lane to a suitable space and curbing avoidance support when conditions are not suitable for crossing, such as low traffic volume or unsuitable lane conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If avoidance support is executed whenever a pedestrian is detected, then pedestrian safety is improved, but unnecessary driving control is performed when pedestrians are in areas where crossing is not expected
Solution Approach 1:
The system applies different control strategies based on the local characteristics of the road space. When a pedestrian is detected in a dividing strip or area with barriers, the system recognizes this specific location's properties and adjusts the avoidance support accordingly, rather than applying a uniform response to all pedestrian detections.
Solution Approach 2:
The avoidance support is dynamically adjusted based on real-time recognition of pedestrian behavior and spatial conditions. The system continuously evaluates whether the pedestrian is moving toward a crossable area and modifies the control intensity accordingly, transitioning from full avoidance support to reduced or no support when appropriate.
2Device complexity
If the system assumes pedestrians do not cross barriers, then control complexity is reduced, but false avoidance maneuvers occur when pedestrians do cross in dividing strips
Solution Approach 1:
The system performs preliminary recognition of the space type (whether it is a dividing strip with barriers or a crossable area) before executing avoidance control. This advance identification allows the system to prepare appropriate control strategies and avoid unnecessary maneuvers when pedestrians are in non-crossable areas.
Solution Approach 2:
The system continuously monitors pedestrian position and movement to verify whether they are actually crossing into the vehicle's lane. This feedback mechanism allows the system to correct its assumptions in real-time, maintaining control accuracy even when pedestrians behave unexpectedly.

AI summary
A vehicle control apparatus, a vehicle control method, and a program that can curb unnecessary driving control are provided. The vehicle control apparatus includes a pedestrian recognition unit configured to recognize a crossing pedestrian crossing a road on which a vehicle travels, a space recognition unit configured to recognize whether there is a space having a predetermined width or more between a lane on which the vehicle travels and an oncoming lane, and a driving control unit configured to execute avoidance support for avoiding contact between the vehicle and the crossing pedestrian recognized by the pedestrian recognition unit based on a behavior of the crossing pedestrian and a behavior of the vehicle, in which the driving control unit is configured to determine whether the crossing pedestrian recognized by the pedestrian recognition unit is moving from the oncoming lane side to a space recognized by the space recognition unit, and curb the avoidance support upon determination that the crossing pedestrian is moving to the space.
