Vehicle Control System for Inattentive Driver Detection and Rest Area Guidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicles, such as large trucks, face increased accident risks due to varying shaft loads and inattentive driving, with conventional inattention warning systems struggling to prevent accidents when drivers ignore warnings.
Innovation Solution
An apparatus and method that detect inattentive driving states, automatically guiding the vehicle to a rest area and adjusting alarm times based on road conditions, while also regulating cabin temperature for driver comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional inattention warning system only outputs a warning alarm to a driver, then the system complexity is low, but the reliability of preventing accidents deteriorates when the driver ignores the warning alarm
Solution Approach 1:
The system performs preliminary actions by automatically guiding the vehicle to a rest area before an accident can occur. When inattentive driving is detected, the system proactively navigates the vehicle to the nearest rest area and automatically parks it, preventing potential accidents before they happen rather than just warning the driver.
Solution Approach 2:
The system enables self-service by allowing the vehicle to automatically guide itself to a rest area and perform parking maneuvers without driver intervention. The control apparatus autonomously controls steering, acceleration, and braking to complete the parking process, making the vehicle serve itself when the driver is inattentive.
2Reliability
If the vehicle automatically enters a rest area when the driver is inattentive, then the reliability of accident prevention is improved, but the ease of operation deteriorates due to automatic control intervention
Solution Approach 1:
The system applies preliminary anti-action by outputting warning messages before automatically guiding the vehicle to a rest area. This preliminary warning gives the driver a chance to correct their inattentive behavior before the system intervenes with automatic control, respecting driver autonomy while still preparing for safety intervention if needed.
3Productivity
If the system guides the vehicle to a rest area and automatically parks, then the productivity of ensuring driver rest is improved, but the device complexity increases due to automatic driving control functions
Solution Approach 1:
The control apparatus performs multiple functions: it detects inattentive driving states, outputs warning messages, guides the vehicle to rest areas, controls parking maneuvers, and even regulates cabin temperature. By making the control apparatus universal and multi-functional, the system achieves high productivity in ensuring driver rest without adding separate dedicated systems for each function.
4Adaptability or versatility
If alarm time is adjusted based on road conditions, then the adaptability to different driving environments is improved, but the device complexity increases due to real-time road condition monitoring
Solution Approach 1:
The system implements feedback by continuously monitoring road conditions and using this information to adjust alarm times. The control apparatus receives real-time road condition data, processes this feedback information, and dynamically modifies the alarm schedule accordingly, creating a closed-loop system that adapts to changing driving environments.

AI summary
An apparatus, a method, and a system are configured for controlling driving of a vehicle. The apparatus for controlling driving of a vehicle includes a determination device that determines whether a driver is in an inattentive driving state during driving. The apparatus also includes a controller that switches a driving mode of the vehicle into a rest mode when it is determined that the driver is in the inattentive driving state. The controller also controls the vehicle to enter a rest area when the vehicle reaches the rest area on a traveling path of the vehicle.
