Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems cannot effectively share driving state information, such as driving skill and cognitive and judgment ability, between vehicles, limiting drivers' ability to adjust their behavior based on the states of other drivers.
Innovation Solution
A driving state sharing device and system that includes a driver state detector, traveling position detector, communication unit, and presentation unit to transmit and receive driver state and position information, allowing drivers to recognize and respond to the states of other vehicles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver state information is detected and shared among vehicles, then drivers can adjust behavior in response to other drivers' states, but the device complexity increases due to multiple detectors and communication units
Solution Approach 1:
The driver state detector is designed to detect multiple types of driver states simultaneously (driving skill, cognitive and judgement ability, arousal degree) using a single integrated detection system. This multi-functional approach allows the system to gather comprehensive driver state information without requiring separate detection devices for each parameter, thereby improving safety while controlling complexity.
Solution Approach 2:
A communication unit serves as an intermediary that transmits driver state information between vehicles. This mediator enables drivers to become aware of other drivers' states (such as low arousal degree or poor driving skill) and adjust their behavior accordingly, improving overall driving safety without requiring direct complex interaction between all system components.
2Object-affected harmful factors
If hazard light is turned to warn surrounding vehicles, then the warning is visible, but the meaning of the warning is not clear to other drivers
Solution Approach 1:
The system uses color-coded visual indicators to represent different driver states. For example, vehicles with low arousal degree or poor driving skill are displayed with specific colors that are intuitively recognizable. This color-coding system allows surrounding drivers to quickly understand the state of other drivers without ambiguity, improving information clarity while maintaining visibility.
Solution Approach 2:
The patent replaces the mechanical/physical warning method (turning on hazard lights) with an information-based warning system that uses visual display of driver state data. Instead of relying on the generic hazard light signal, the system substitutes a more informative approach that directly communicates the driver's cognitive and physical state to surrounding vehicles, eliminating the information loss inherent in generic warnings.
