Vehicle Traveling Control via Management Server
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle lane change functions are ineffective in addressing dangerous situations caused by driver drowsiness or biometric abnormalities during driving assistance, as they fail to promptly intervene when a driver is unable to respond to hazardous conditions.
Innovation Solution
A vehicle traveling control system that includes sensor devices to detect driver states, a driver state determining device to assess dangerous conditions, and a management server that wirelessly controls the vehicle to move to the end lane and stop when a dangerous situation is detected, ensuring safety through network connectivity and driving assistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If lane change function is interrupted when dangerous situation occurs, then driver safety is improved, but driver response time deteriorates
Solution Approach 1:
The system performs preliminary actions by automatically executing lane change and stopping procedures before the driver can respond to the dangerous situation. When drowsiness or abnormality is detected, the vehicle proactively changes to the end lane and stops, eliminating the need for driver response and preventing potential accidents caused by delayed human reaction.
2Reliability
If wireless control is implemented for automatic lane change and stopping, then driver safety is improved, but system complexity increases
Solution Approach 1:
The management server provides universal control capabilities that can handle multiple driving assistance functions through a single centralized system. The server performs diverse functions including dangerous situation detection, lane change control, and stopping control, reducing the need for separate dedicated systems for each function and thereby managing complexity while maintaining high safety standards.
3Measurement precision
If driver state monitoring is continuously performed, then dangerous situation detection is improved, but energy consumption increases
Solution Approach 1:
The system performs periodic monitoring of driver state through biometric sensors at regular intervals rather than continuous monitoring. This periodic detection approach maintains adequate detection precision for identifying dangerous situations like drowsiness or abnormalities while significantly reducing energy consumption compared to continuous real-time monitoring.

AI summary
A vehicle includes: a plurality of sensor devices that determine a driver state; a driver state determining device that receives detection results from a plurality of sensor devices and determines whether the driver state is a dangerous state; and a driving assistance device that performs lane keeping control and speed control of a vehicle and transmits a network connection request to a management server when the driver state determining device has determined the dangerous state.
