Solution Overview

Problem

Existing vehicle control devices do not adequately provide information on learning situations based on the traveling direction of a vehicle, limiting the effectiveness of driving assistance and automatic traveling control systems.

Innovation Solution

A vehicle control device that stores learning information associated with the traveling direction and displays a learning status corresponding to the direction, allowing for differentiated displays of learning progress and providing information only relevant to the vehicle's current direction, enhancing the occupant's understanding of the learning status.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If learning information is stored without considering traveling direction, then the system complexity is reduced, but the information providing function is insufficient

Engineering Contradiction:
Improvesystem complexityVSAvoidinformation providing function
Core Design Contradiction:
Device complexityVSLoss of information

Solution Approach 1:

The patent segments learning information storage by traveling direction, creating separate storage areas for different directions (e.g., northbound, southbound, eastbound, westbound). This segmentation allows the system to maintain lower overall complexity while providing direction-specific information, as each segment can be independently managed and processed.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent adds the traveling direction dimension to the learning information storage structure. Instead of a single undifferentiated storage area, the system now stores information across multiple dimensions (location + direction), enabling more precise information retrieval and display tailored to the vehicle's current traveling direction.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Loss of information

If learning status display shows all directions, then complete information is provided, but the occupant cannot easily recognize relevant information

Engineering Contradiction:
Improvelearning status informationVSAvoidoccupant recognition
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The patent extracts and displays only the learning status information relevant to the vehicle's current traveling direction, removing unrelated directional information from the display. This extraction principle ensures that the occupant receives complete relevant information without being overwhelmed by unnecessary data from other directions.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent applies local quality by making the display content dynamic and context-specific. The learning status display adapts its content based on the vehicle's current traveling direction, providing high-quality relevant information locally tailored to the situation rather than a uniform global display of all directional data.

Inventive Principle:
Principle #3Local quality

3Adaptability or versatility

If the system learns all traveling situations uniformly, then comprehensive coverage is achieved, but the information provision is not differentiated

Engineering Contradiction:
Improvelearning coverageVSAvoiddifferentiated information
Core Design Contradiction:
Adaptability or versatilityVSLoss of information

Solution Approach 1:

The patent segments the learning process by traveling direction, creating separate learning contexts for different directions. This allows the system to maintain comprehensive coverage across all directions while differentiating the information provision for each direction, as each segment learns and stores information independently based on its specific traveling context.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent changes the learning parameter from uniform undifferentiated learning to direction-specific learning. By introducing traveling direction as a variable parameter in the learning process, the system achieves both comprehensive coverage (learning all directions) and differentiated information provision (specific information for each direction).

Inventive Principle:
Principle #35Parameter changes

AI summary

A traveling history learning section (17) stores learning information (35) based on the traveling history of the vehicle in association with the position of a to-be-learned zone (Z, Z1 to Z4) and with the traveling direction of the vehicle in the to-be-learned zone (Z, Z1 to Z4). A learning information obtaining section (15) obtains learning information (35) corresponding to the position of a host vehicle (42) from the learning information storage section (16). A display control section (15) displays, on the display section (19), a learning status display (41, 51 to 53, 55 to 57, 62 to 65) showing a learning status corresponding to the traveling direction of the host vehicle.
