Human Driver Network for Autonomous Vehicle Localization Map Updates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The high labor and resource intensity of recording, processing, and distributing highly detailed localization maps for autonomous vehicles (AVs) limits their ubiquity on public roads, as these maps can become stale quickly due to environmental changes, leading to localization map degradation and potential safety issues.
Innovation Solution
An on-demand transport facilitation system leverages a human-driver network to identify and resolve local anomalies by deploying drivers with suitable sensors to record and update localization maps, reducing the need for continuous map refreshment and processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If continuous recording and processing of localization maps is performed to maintain high precision, then mapping precision is improved, but labor intensity and resource consumption increase
Solution Approach 1:
The system enables human drivers to perform self-service map updating by capturing images of road features using their mobile devices during normal driving. Drivers automatically contribute to localization map maintenance without requiring specialized processing systems, thereby improving map precision while reducing system complexity and resource consumption.
2Reliability
If detailed localization maps are continuously updated to reflect environmental changes, then reliability of AV operations is improved, but loss of time and resources increases
Solution Approach 1:
The system implements feedback mechanisms where AVs detect anomalies by comparing sensor data with existing localization maps, then trigger targeted updates only in affected areas. Human drivers are deployed selectively to capture images of identified anomalies, ensuring map reliability is maintained while minimizing time and resource loss through selective rather than continuous updating.
3Measurement precision
If human drivers are deployed to capture images of local anomalies, then localization map quality is improved, but labor intensity decreases compared to traditional methods
Solution Approach 1:
The system uses human drivers as intermediaries between AV sensors and the localization map database. Drivers capture images of road features using their mobile devices and transmit them to update specific portions of localization maps, thereby improving map quality while avoiding the need for complex centralized processing infrastructure.

AI summary
An on-demand transport system can manage an on-demand transportation service for a given region by matching requesting users with drivers and the AVs, where the AVs utilize localization maps and live sensor data to autonomously operate throughout the given region. The transport system can identify a local anomaly within the given region that affects AV performance. The transport system can transmit a routing invitation a driver to provide feedback corresponding to the local anomaly. Based on feedback data received from the driver, the transport system can transmit an update to AVs intersecting the local anomaly to enable the intersecting AVs to resolve the local anomaly.
