Solution Overview
Problem
Autonomous vehicles lack effective emergency handling systems for remote safe driving, which is crucial for ensuring passenger and vehicle safety, especially in situations where rapid and precise responses are necessary to match human driving reliability.
Innovation Solution
A method and system for remote safe driving that includes self-checking and emergency handling capabilities, where a remote monitoring center can control vehicle operations, detect emergency situations, and transmit commands to ensure safety by switching to a low-power mode and periodically transmitting the vehicle's location, and implement vehicular driving actions based on driver behavior classification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If autonomous vehicles implement comprehensive emergency handling systems with remote monitoring and control capabilities, then safety and reliability of autonomous driving is improved, but device complexity and system cost increase
Solution Approach 1:
The emergency handling system is segmented into multiple independent modules: emergency detection module, low-power mode module, remote monitoring center, and secure communication module. Each module performs a specific function, allowing the complex system to be managed through modular components that can be developed, tested, and maintained independently while collectively providing comprehensive safety assurance.
Solution Approach 2:
A remote monitoring center acts as an intermediary between the autonomous vehicle and external support systems. This intermediary receives vehicle status data, processes emergency situations, and provides guidance commands, thereby distributing system complexity across multiple entities rather than concentrating all functions within the vehicle itself.
2Use of energy by moving object
If the vehicle switches to low-power operation mode by shutting down subsets of vehicular components during emergencies, then energy consumption is reduced and safety is improved, but functionality and operational capability are reduced
Solution Approach 1:
The vehicle's operational mode is made dynamic through the ability to switch between normal operation and low-power emergency mode. The system dynamically adjusts its functionality based on the emergency situation, shutting down non-essential components to conserve energy while maintaining critical safety functions, and can transition back to full functionality when the emergency is resolved.
Solution Approach 2:
During emergency situations, the system applies partial action by selectively shutting down only the necessary non-essential components rather than all systems. This allows the vehicle to maintain minimum viable functionality for safety and communication while reducing power consumption sufficiently to extend operational duration during emergencies.
3Reliability
If the vehicle periodically transmits location data to remote monitoring center during emergencies, then safety monitoring is improved, but communication energy consumption and data transmission requirements increase
Solution Approach 1:
The vehicle implements periodic transmission of location data to the remote monitoring center during emergency situations rather than continuous transmission. This periodic action maintains adequate safety monitoring by providing location updates at sufficient intervals while significantly reducing communication energy consumption and network resource usage compared to continuous data streams.
4Reliability
If the system implements secure communication protocols for remote monitoring and control, then security and data protection are improved, but communication overhead and processing time increase
Solution Approach 1:
Security protocols and encrypted communication channels are established and configured in advance before emergency situations occur. Authentication mechanisms, encryption keys, and secure communication pathways are pre-set during system initialization or previous operational phases, allowing the system to immediately activate protected communication during emergencies without the time penalty of establishing security measures in real-time.

AI summary
Disclosed are devices, systems and methods for remote safe driving. One exemplary method includes detecting an emergency situation, and in response to the detecting the emergency situation, switching operation of the vehicle to a low-power operation mode that comprises shutting down a subset of vehicular components, and periodically transmitting a location of the vehicle to a remote monitoring center. Another exemplary method includes selecting at least one of a set of vehicular driving actions, and transmitting, over a secure connection, the at least one of the set of vehicular driving actions to the vehicle, wherein the set of vehicular driving actions is generated based on a classification of driver behavior.
