Solution Overview

Problem

Autonomous driving vehicles face challenges in recognizing and adhering to varying regional regulations regarding autonomous driving, which can lead to safety concerns and legal issues due to differences in laws across countries and states, as well as specific restrictions on road sections.

Innovation Solution

A map information storage device and an autonomous driving control device that store and transmit autonomous driving regulatory information to vehicles, allowing them to recognize and adjust their autonomous driving functions according to the regulations of each road section, thereby ensuring compliance and safety.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If map information is frequently updated to ensure latest traffic data, then data freshness is improved, but communication time and power consumption increase

Engineering Contradiction:
Improvedata freshnessVSAvoidcommunication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by storing map information locally in advance and updating it only when necessary (when traffic information indicates a change). This allows the autonomous vehicle to have latest map data ready before needed, reducing frequent communication cycles and saving time while maintaining data freshness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from traffic information to trigger map information updates only when actual traffic conditions change. By monitoring traffic information and comparing it with stored map data, the system updates map information selectively rather than frequently, reducing communication time while ensuring data remains fresh when needed.

Inventive Principle:
Principle #23Feedback

2Reliability

If map information is frequently updated to ensure latest traffic data, then data freshness is improved, but power consumption increases

Engineering Contradiction:
Improvedata freshnessVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The system performs preliminary actions by storing map information locally in advance and updating it only when necessary (when traffic information indicates a change). This allows the autonomous vehicle to have latest map data ready before needed, reducing frequent communication cycles and saving power while maintaining data freshness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system uses feedback from traffic information to trigger map information updates only when actual traffic conditions change. By monitoring traffic information and comparing it with stored map data, the system updates map information selectively rather than frequently, reducing power consumption while ensuring data remains fresh when needed.

Inventive Principle:

3Measurement precision

If detailed map information is stored to improve positioning accuracy, then positioning precision is improved, but data storage requirements increase

Engineering Contradiction:
Improvepositioning precisionVSAvoiddata storage
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The system applies local quality by storing detailed map information (such as lane markings, road boundaries, and geographic features) only in the relevant local areas where the autonomous vehicle operates. Instead of storing complete global map data, the system maintains detailed information locally for positioning while using less detailed traffic information for broader context, reducing overall data storage requirements while maintaining positioning precision.

Inventive Principle:
Principle #3Local quality

AI summary

A server device 2 stores a distribution map DB 21 including autonomous driving regulatory information Ir for regulating autonomous driving of a vehicle in a predetermined section, and sends map data D1 including the autonomous driving regulatory information Ir to a driving assistance device 1. Then, the driving assistance device 1 receives the map data D1 including the autonomous driving regulatory information Ir and controls the autonomous driving of the vehicle based on the received autonomous driving regulatory information Ir.
