Vehicle Experience Sharing for Autonomous Driving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic vehicle operation technologies rely solely on the experience of individual vehicles, resulting in varying performance levels and limited capability in inexperienced situations, as they lack access to collective experience data from other vehicles.
Innovation Solution
A system where vehicles can share and receive experience information through inter-vehicle communication, allowing inexperienced vehicles to utilize the driving data of experienced vehicles for improved automatic operation performance, using a computing system that optimizes and updates this information for enhanced driving control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automatic operation learning function uses only own vehicle's experience data, then the system complexity remains low, but the automatic operation performance is limited and varies by vehicle
Solution Approach 1:
The patent combines experience data from multiple vehicles into a shared database, allowing each vehicle to benefit from collective experience. The server merges data from multiple sources to create comprehensive experience information that improves automatic operation performance across all connected vehicles.
Solution Approach 2:
The shared experience database serves multiple vehicles simultaneously, making the system universally applicable. The same database infrastructure supports data collection, storage, processing, and distribution to numerous vehicles, achieving multi-functionality.
2Reliability
If automatic operation learning function shares experience data among vehicles, then the automatic operation performance improves, but the communication system complexity increases
Solution Approach 1:
The server acts as an intermediary between vehicles, handling the complex tasks of data collection, processing, storage, and distribution. This mediator absorbs the communication system complexity, allowing individual vehicles to have simpler communication interfaces while still benefiting from shared experience data.
3Reliability
If inexperienced vehicle operates without shared experience data, then the device complexity remains low, but the driving safety and performance are compromised
Solution Approach 1:
The system performs preliminary actions by collecting and processing experience data in advance through the server. When an inexperienced vehicle encounters a situation, the relevant experience information has already been prepared and is readily available, eliminating the need for complex real-time data processing in the vehicle itself.
Data Source
AI summary
Provided is a system whereby the self-driving capability or each vehicle can be improved by using not only an experience of own vehicle but also an experience of another vehicle. For example, suppose own vehicle (V1) has no experience of having traveled on a root (R). On the other hand, another vehicle (V2) has experienced traveling on the root (R). The another vehicle (V2) acquires various data pertaining to driving when traveling on the route (R), and stores the various data in an onboard storage device. The another vehicle (V2) provides information including the various data stored in the storage device to the own vehicle (V1) as experience information. The own vehicle (V1) can achieve self-driving capability at the same level as the another vehicle (V2) by performing self-driving control on the basis of the experience information of the another vehicle (V2), which has experience of having traveled on the root (R).
