Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems lack appropriate guidance when reminding drivers to intervene in vehicle operation, potentially leading to safety hazards due to driver unawareness or inability to take over.
Innovation Solution
A driver intervention guiding system and method that utilize a processor with multiple modules to detect driver conditions, vehicle dynamics, and environmental factors, calculate intervention parameters, and execute scripts to guide the driver appropriately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the system reminds the driver to intervene without appropriate guidance, then the driver may not understand what action to take, but the system complexity increases to provide detailed guidance
Solution Approach 1:
The system changes the parameter of guidance content based on detected driver conditions (attention level, stress level, operation capability). When driver attention is high, simple reminders are provided; when attention is low, more detailed guidance with specific operation steps is provided. This dynamic parameter adjustment resolves the contradiction by providing appropriate complexity only when necessary.
Solution Approach 2:
The system continuously detects driver conditions (attention, stress, operation state) and uses this feedback to adjust the guidance provided. The feedback loop ensures that guidance complexity matches actual driver needs, improving intervention effectiveness without unnecessarily increasing system complexity.
2Reliability
If the system provides detailed guidance to help driver intervene, then driver safety improves, but the response time may be delayed
Solution Approach 1:
The guidance system dynamically adjusts its behavior based on real-time driver conditions and situation urgency. When driver attention is already high or situation is not critical, brief reminders are given allowing quick intervention. When driver attention is low or situation is critical, detailed step-by-step guidance is provided to ensure safe intervention, accepting longer response time as necessary for safety.
Solution Approach 2:
Different levels of guidance detail are provided based on local driver conditions. The system identifies specific aspects of driver state (attention level, stress level, current operation) and provides guidance tailored to that local condition, optimizing the balance between safety and response time for each specific situation.
3Measurement precision
If the system monitors multiple driver conditions and environmental factors, then intervention accuracy improves, but the detection and processing complexity increases
Solution Approach 1:
The detection system is segmented into specialized modules: driver condition detecting device (monitoring attention, stress, operation), vehicle dynamic detecting device (monitoring vehicle state), and environment detecting device (monitoring surrounding environment). Each module focuses on specific parameters, improving measurement precision while distributing complexity across separate functional units rather than one monolithic complex system.

AI summary
A driver intervention guiding system includes a processor. The processor includes a driver condition identifying module, a vehicle dynamic identifying module, an environment identifying module, a system diagnosis module, a driver intervention parameter calculating module, a scrip database, and a scrip executing module. The driver condition identifying module provides a driver value based on a condition of a driver. The vehicle dynamic identifying module provides a vehicle dynamic value based on a dynamic of a vehicle. The environment identifying module provides an environment value based on a driving environment of the vehicle. The system diagnosis module provides a diagnostic value. The driver intervention parameter calculating module calculates a driver intervention parameter based on the driver value, the vehicle dynamic value, the environment value and the diagnostic value. The scrip executing module selects one of scrips of the scrip database based on the driver intervention parameter.
