Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring technologies for predicting risky driving behaviors, such as drunk or fatigued driving, are indirect and prone to inaccuracies due to external environmental factors, failing to objectively assess a driver's responsiveness and judgment before starting a vehicle.
Innovation Solution
A brain-computer interface (BCI) system that acquires and analyzes electroencephalogram signals from drivers performing responsiveness tests, providing direct and objective feedback on their suitability to drive, using a test module, information acquisition and analysis module, and processor module to determine risky driving behaviors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If indirect monitoring technologies (alcohol content monitoring, sweat component monitoring, eyeball movement tracking) are used to predict risky driving behavior, then monitoring coverage is improved, but measurement precision deteriorates due to external environmental factor disturbance
Solution Approach 1:
The patent replaces indirect mechanical/chemical monitoring systems (alcohol sensors, sweat analysis, eye tracking) with a brain-computer interface that directly measures neural electrical signals. The EEG-based BCI system substitutes physical/chemical detection with direct neural signal acquisition, eliminating interference from external environmental factors such as masks, gloves, or fermented food that affect traditional sensors.
Solution Approach 2:
The patent introduces electroencephalogram signals as an intermediary between the driver's internal state and the monitoring system. Instead of directly detecting physical manifestations of driving state (breath, sweat, eye movement), the system uses EEG signals as a mediator that directly reflects brain activity related to responsiveness and judgment, providing accurate measurement without external interference.
2Ease of operation
If indirect monitoring technologies are used to detect driver state, then ease of operation is improved (no body movement required), but reliability deteriorates due to false triggering from external factors
Solution Approach 1:
The patent replaces mechanical detection methods that require body movement or physical contact (eye tracking, sweat collection) with a BCI system that detects electrical neural signals. This substitution maintains ease of operation while dramatically improving reliability by eliminating false positives from external factors like masks, gloves, or fermented food that interfere with traditional sensors.
Solution Approach 2:
The patent creates a direct electrical copy of the driver's neural activity through EEG signals, bypassing the need for physical interaction or body movement. This electrical copying of brain states provides reliable measurement of responsiveness and judgment without the reliability issues of indirect physical measurements affected by external environmental factors.
3Measurement precision
If traditional monitoring methods requiring body movement or language response are used, then ease of operation deteriorates, but measurement precision is improved through direct observation of driver actions
Solution Approach 1:
The patent replaces mechanical response requirements (body movement, language output) with direct neural signal detection through EEG. This allows the system to measure responsiveness and judgment accuracy by detecting brain electrical patterns during cognitive tasks, eliminating the need for physical movement or speech while maintaining or improving measurement precision through direct neural observation.
Solution Approach 2:
The patent uses EEG signals as an intermediary to observe driver cognitive state without requiring physical action. Instead of watching body movements or listening to language responses, the system directly monitors neural electrical activity that reflects responsiveness and judgment, providing accurate assessment with greater ease of operation since no physical response is needed from the driver.

AI summary
The present invention provides a risky driving prediction method and system based on a brain-computer interface, and an electronic device. The risky driving prediction method based on the brain-computer interface includes: performing, by a driver, at least one responsiveness test item before starting a vehicle; applying a brain-computer interface to acquire an electroencephalogram signal of the driver performing the at least one responsiveness test item, and analyzing the electroencephalogram signal to generate feedback information; and analyzing the feedback information based on a preset test standard to determine whether the driver has a risky driving behavior. Therefore, by using the risky driving prediction method, it can be detected whether the driver is in a state suitable for driving the vehicle without requiring the driver to do any body movement or language response.
