Vehicle Collision Mitigation via Object-Type Activation Timing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing collision mitigation systems for vehicles activate control measures uniformly, regardless of the type of object involved in a potential collision, leading to unnecessary activation when colliding with roadside objects and delayed activation when encountering pedestrians.
Innovation Solution
A collision mitigation apparatus that includes an activation control section, a type determining section, and an activation condition changing section, which detects objects around the vehicle, determines their type, and adjusts the activation timing based on the object's type, thereby optimizing the activation timing for different scenarios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If uniform activation timing is used for all objects, then the system is simple to operate, but unnecessary control is performed for roadside objects and necessary control is delayed for pedestrians
Solution Approach 1:
The system applies different activation timing settings based on the local characteristics of the detected object type. Roadside objects receive one activation timing configuration while pedestrians receive another, allowing each object category to receive optimized treatment rather than a uniform approach
2Reliability
If activation timing is adjusted by object type, then control accuracy is improved, but device complexity increases due to type determination requirements
Solution Approach 1:
The system segments the object detection space into distinct categories (roadside objects, pedestrians, other vehicles) and applies specific activation timing rules to each segment. This segmentation allows the complex problem of universal optimization to be broken down into manageable category-specific rules

AI summary
A collision mitigation apparatus is provided, which is installed in a vehicle and mitigates damage to the vehicle in occurrence of a collision. The apparatus includes an activation control section which detects an object positioned around the vehicle, and activates a collision mitigation part for mitigating damage to the vehicle in occurrence of a collision if a positional relationship between the vehicle and the object meets a predetermined activation condition, a type determining section which determines type of the object, the type being any one of a vehicle, a pedestrian and a roadside object, and an activation condition changing section which consolidates the activation condition compared to a case where the type of the object is not a roadside object, if the type of the object is a roadside object.
