Solution Overview

Problem

Conventional vehicle recognition systems provide unnecessary warnings to drivers by sensing and alerting them to less-dangerous obstacles, causing inconvenience and potentially distracting them from more critical situations.

Innovation Solution

A recognition support system that includes an object detection device, direction sensing device, range setting device, and information presenting device, which selectively presents information to the driver based on the turning direction, object category, and object state, prioritizing objects that are independently moving and within the notification range, allowing the driver to focus on the most critical objects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the conventional device provides warnings for all obstacles within sensing range, then the driver is informed of all potential hazards, but the driver experiences inconvenience and distraction from unnecessary information

Engineering Contradiction:
Improvesafety warning coverageVSAvoiddriver convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The system applies different notification strategies to different spatial zones around the vehicle. The notification range is dynamically adjusted based on turning direction, creating zone-specific warning areas rather than uniform coverage. This allows the system to provide comprehensive safety warnings in critical zones while reducing notifications in less dangerous areas, resolving the contradiction between complete hazard awareness and driver convenience.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The notification range is made dynamic rather than static. The range setting device adjusts the warning area based on the turning direction detected by the direction sensing device. When the vehicle is about to turn, the notification range is restricted to areas relevant to that turning direction, automatically adapting the information presented to the driver's current operational context and reducing unnecessary warnings.

Inventive Principle:
Principle #15Dynamics

2Loss of information

If the system presents information about all detected objects, then the driver has complete awareness of the environment, but the driver is overwhelmed by excessive information

Engineering Contradiction:
Improveenvironmental awarenessVSAvoidinformation processing load
Core Design Contradiction:
Loss of informationVSDevice complexity

Solution Approach 1:

The system extracts and presents only the most relevant object information based on the turning direction and object state. The selecting device filters out objects that are not critical to the current turning maneuver, extracting only those objects within the dynamically determined notification range. This reduces information overload while maintaining essential environmental awareness.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The system changes the parameter of information selection based on object state. Objects that are independently moving (such as pedestrians or cyclists) are prioritized for notification over stationary objects. This parameter-based filtering allows the system to maintain comprehensive awareness of the environment while reducing the information load by focusing on dynamically changing, more critical elements.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If the notification range is expanded to cover all possible turning paths, then no potential hazard is missed, but the driver receives unnecessary warnings in safe zones

Engineering Contradiction:
Improvehazard detection coverageVSAvoidfalse alarm frequency
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The notification range is customized for each turning direction rather than using a uniform expanded range. The range setting device defines specific notification areas corresponding to left turns, right turns, or straight-ahead paths. This local quality approach ensures comprehensive hazard detection within each turning path while avoiding false alarms in zones that are not relevant to the current intended maneuver.

Inventive Principle:
Principle #3Local quality

AI summary

A recognition support system includes: an object detection device detecting an object that is located in a periphery of a host vehicle; a direction sensing device sensing a direction to which a driver intends to turn the host vehicle; a range setting device setting a notification range based on the direction sensed by the direction sensing device; a selecting device defining the object, which is detected by the object detecting device, as a specified object when the object moves independently from the host vehicle, and selecting the specified object, which is located within the notification range, to be presented to the driver based on a state of the specified object; and an information presenting device presenting an information enabling the driver to recognize the specified object selected by the selecting device.
