Vehicle Processing Device Emergency Peer-to-Peer Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Autonomous driving vehicles face challenges in cooperative operation during emergencies when communication with a central server is disrupted, leading to potential failures in responding to situations like earthquakes or tsunamis due to network failures or congestion.
Innovation Solution
A processing device mounted in vehicles searches for and communicates with other vehicles to establish a peer-to-peer network, allowing a center vehicle to take control and coordinate responses even when the central server is unreachable, using direct communication methods like WiFi or Bluetooth to ensure intervention control instructions can be transmitted.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a management server transmits control signals to autonomous driving vehicles, then cooperative operation can be performed, but the system fails when communication network is disconnected
Solution Approach 1:
The patent introduces other autonomous driving vehicles as intermediary nodes to relay control signals when the management server is inaccessible. The host vehicle searches for and communicates with other vehicles, which can forward instructions, thereby maintaining cooperative operation capability without direct server connection.
Solution Approach 2:
The patent segments the centralized control architecture into distributed vehicle-to-vehicle communication units. Each vehicle becomes an independent control node capable of searching for, communicating with, and relaying instructions from other vehicles, dividing the monolithic server-dependent system into multiple autonomous segments.
2Ease of operation
If autonomous driving vehicles operate independently during emergencies, then vehicle autonomy is maintained, but coordinated response among multiple vehicles cannot be achieved
Solution Approach 1:
The patent merges multiple independent vehicle systems into a coordinated group by enabling direct communication between vehicles. The host vehicle searches for and combines resources with other vehicles, allowing them to function as a unified team while maintaining individual autonomy, thus achieving both ease of operation and reliable coordinated response.
3Loss of information
If communication with center server is required for intervention control, then centralized management is achieved, but response time increases due to network latency or failure
Solution Approach 1:
The patent implements preliminary action by pre-establishing vehicle-to-vehicle communication channels and pre-identifying nearby vehicles as potential relays before emergency situations occur. When emergencies arise, these pre-established communication paths enable immediate instruction transmission without waiting for server connectivity or establishing new communication channels.

AI summary
Disclosed is a processing device that is mounted in a vehicle and is able to perform communication with a center server during a normal time. The processing device includes a controller configured to execute searching for one or a plurality of other vehicles with which a host vehicle is able to perform communication, in emergency where a situation of emergency occurs and communication with the center server is disrupted, inquiring the other vehicles searched by the search about whether or not to enable intervention control related to the situation, and deciding a center vehicle giving an instruction related to the intervention control from among the other vehicles replying to enable the intervention control and the host vehicle.
