Solution Overview

Problem

Existing driving assistance systems, such as lane departure warning systems (LDWS) and lane keeping assistance systems (LKAS), are inadequate in preventing accidents caused by drivers who are insensitive to changes in their vehicle's surroundings, as they do not effectively address the issue of decreased driver concentration leading to unrecognized dangerous situations.

Innovation Solution

A safe driving guiding system that extracts a vehicle-drivable space and a dynamic driving space using sensors, determining the overlap between these spaces to control the initiation of LDWS and LKAS operations, thereby preventing accidents by alerting or automatically adjusting the vehicle's driving mode.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If LDWS is used to warn drivers of lane departure, then drivers are notified of dangerous situations, but the system does not fundamentally solve the problem of driver insensitivity to surrounding environment changes

Engineering Contradiction:
Improveaccident prevention capabilityVSAvoidresponse to driver concentration levels
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts its operation based on the driver's concentration level. When the driver is determined to be insensitive to surrounding environment changes, the system transitions from passive warning mode to active intervention mode, automatically controlling the steering wheel to maintain lane position.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The system continuously monitors the driver's concentration level through sensors that detect eye movement, head position, and steering patterns. This feedback loop allows the system to adapt its assistance level in real-time, increasing intervention when driver attention deteriorates.

Inventive Principle:
Principle #23Feedback

2Reliability

If multiple sensors are used to extract vehicle-drivable space and dynamic driving space, then the system can determine overlap degree for safe driving guidance, but the device complexity increases

Engineering Contradiction:
Improvesafe driving guidance accuracyVSAvoidsensor integration and processing
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system uses multi-functional sensors that serve multiple purposes. For example, the same sensors detecting surrounding objects are used to determine both the vehicle-drivable space and the dynamic driving space, reducing the need for separate sensor systems while maintaining comprehensive monitoring capability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
