Solution Overview
Problem
Current autonomous vehicle systems lack effective remote monitoring and control capabilities, particularly in emergency situations or when drivers become unfit to drive, leading to safety concerns and increased costs due to mandatory breaks and system limitations.
Innovation Solution
A method and system for remotely controlling vehicles using sensor systems to create external and internal situation images, which are transmitted wirelessly to a remote control unit, allowing for vehicle control based on specified trajectories and occupant health monitoring, enabling continuous safe operation even when drivers are unfit.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If autonomous driving systems are implemented, then productivity and service capability are improved, but reliability deteriorates when drivers become unfit or system limits are reached
Solution Approach 1:
A remote control device acts as an intermediary between the autonomous vehicle system and human operators. When the driver becomes unfit or system limits are reached, the remote control device receives situation images from the vehicle's sensors and enables remote intervention, thereby maintaining reliability while preserving autonomous operation benefits.
Solution Approach 2:
The system performs preliminary actions by continuously monitoring driver fitness and system operational status through sensor data. Before critical failures occur, the system prepares situation images and maintains communication channels ready for remote intervention, ensuring reliability is maintained proactively rather than reactively.
2Reliability
If mandatory breaks are enforced for drivers, then health and safety are improved, but productivity deteriorates due to vehicle idle time
Solution Approach 1:
The vehicle performs self-service during driver breaks by autonomously monitoring its own situation through sensor systems and maintaining readiness for remote control. This allows the vehicle to remain operational or be remotely managed while the driver takes mandatory health breaks, preserving both driver welfare and operational continuity.
Solution Approach 2:
The system prepares for continuous operation by pre-establishing remote control capabilities and situation monitoring before breaks begin. This preliminary preparation ensures that productivity is maintained during breaks through remote intervention possibilities, while driver health requirements are still met.
3Reliability
If remote control capabilities are added, then reliability is improved through emergency intervention, but device complexity increases
Solution Approach 1:
The remote control device is designed with multi-functionality, serving as a universal interface that can handle various emergency situations, routine monitoring tasks, and communication functions. This consolidates multiple specialized systems into a single device, improving reliability without proportionally increasing overall system complexity.
Solution Approach 2:
The system creates simplified copies of the vehicle's situation through transmitted images and data representations. Rather than complex direct control of all vehicle systems, the remote control device receives processed situation copies that enable effective intervention while keeping the device architecture relatively simple.
4Reliability
If continuous monitoring is implemented, then safety is improved, but energy consumption increases
Solution Approach 1:
The continuous monitoring system operates periodically rather than continuously at full capacity. Situation images are captured and transmitted at intervals or triggered by specific events, providing adequate safety monitoring while significantly reducing energy consumption compared to constant high-rate monitoring.
Solution Approach 2:
The monitoring system applies partial action by focusing computational and transmission resources on critical safety parameters rather than monitoring all vehicle systems at maximum intensity. This selective monitoring approach maintains safety while optimizing energy consumption.
