Solution Overview

Problem

Autonomous driving systems face challenges in providing real-time information about available autonomous driving levels and surrounding environments to drivers, making it difficult for them to switch vehicle control in unexpected situations, especially when autonomous driving is partially used.

Innovation Solution

An autonomous driving control system and method that determines map accuracy and sensor coverage to recommend driving paths with indicated autonomous driving levels, providing real-time updates to drivers on the current and predicted autonomous driving levels, allowing them to prepare for control switches.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If autonomous driving is partially used, then the system complexity is reduced, but the driver cannot receive information about unexpected situations and cannot switch vehicle control in time

Engineering Contradiction:
Improveautonomous driving levelVSAvoidinformation about unexpected situations
Core Design Contradiction:
Extent of automationVSLoss of information

Solution Approach 1:

The system continuously provides feedback to the driver about the current autonomous driving level, map accuracy, and sensor coverage status. This includes real-time notifications when the autonomous driving level changes or when unexpected situations are detected, enabling the driver to maintain situational awareness and switch control appropriately.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-notifying the driver about upcoming changes in autonomous driving level or potential unexpected situations before they occur. This allows the driver to prepare for control switching in advance, reducing reaction time and improving safety.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If map accuracy is low, then the system cost is reduced, but the available autonomous driving level is limited

Engineering Contradiction:
Improvemap accuracyVSAvoidautonomous driving level
Core Design Contradiction:
Measurement precisionVSExtent of automation

Solution Approach 1:

The system dynamically adjusts the autonomous driving level based on the map accuracy parameter. When map accuracy is insufficient, the system automatically reduces the autonomous driving level to appropriate stages, ensuring safe operation while still providing useful driver assistance functions. This parameter-based adaptation allows the system to optimize performance for different map quality conditions.

Inventive Principle:
Principle #35Parameter changes

3Device complexity

If sensor coverage is insufficient, then the device complexity is reduced, but the autonomous driving level for each section cannot be determined

Engineering Contradiction:
Improvesensor coverageVSAvoidautonomous driving level determination
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The system determines autonomous driving levels on a local section-by-section basis rather than uniformly across all areas. Each road section is evaluated independently based on the actual sensor coverage and environmental conditions, allowing the system to provide autonomous driving functionality where sensors are sufficient while maintaining safety in areas with limited coverage.

Inventive Principle:
Principle #3Local quality

AI summary

An autonomous driving control method of a vehicle is provided. The method includes recognizing accuracy of a map within the vehicle and determining an available autonomous driving level. Sensor coverage of the vehicle is recognized and an available autonomous driving level for each section among the available autonomous driving levels is determined. A path with autonomous driving level indicated thereon among driving paths is then recommended according to a destination set in the map, and autonomous driving level calculation information is updated in real-time according to a selected path and autonomous information is provided to a driver.
