Solution Overview

Problem

Existing advanced driver assistance systems (ADAS) and autonomous driving (AD) features face challenges in efficiently managing map data transmission, leading to suboptimal performance and increased network traffic due to the lack of dynamic adjustment based on current conditions and feature requirements.

Innovation Solution

A user equipment (UE) dynamically adjusts map data transmission by aggregating and optimizing data based on current environmental conditions and ADAS/AD feature needs, predicting requirements for upcoming events, and utilizing sensor and V2X data to ensure functional quality and reduce unnecessary data transfer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If map data is transmitted to ensure ADAS/AD feature performance, then functional quality is improved, but network traffic increases

Engineering Contradiction:

Improvefunctional qualityVSAvoidnetwork traffic

Core Design Contradiction:

ReliabilityVSLoss of energy

Solution Approach 1:

The system dynamically adjusts map data transmission based on real-time conditions. The UE evaluates current environmental conditions and ADAS/AD feature requirements to determine the appropriate level of map data to request and receive, transitioning from static to dynamic data management strategies

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes parameters such as the amount, type, and frequency of map data transmission based on evaluated conditions. Different data granularity levels are selected depending on whether the vehicle meets threshold requirements for ADAS/AD features, optimizing the balance between functional quality and network traffic

Inventive Principle:

Principle #35Parameter changes

2Productivity

If map data is transmitted to meet feature requirements, then system performance is improved, but data transmission demands increase

Engineering Contradiction:

Improvesystem efficiencyVSAvoiddata transmission volume

Core Design Contradiction:

ProductivityVSQuantity of substance

Solution Approach 1:

The system requests and transmits only the necessary portion of map data required to meet ADAS/AD feature requirements. By evaluating current conditions and feature thresholds, the system avoids excessive data transmission while ensuring sufficient data for optimal system performance

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The system performs preliminary evaluation of current environmental conditions and feature requirements before initiating map data transmission. This advance assessment enables the system to pre-determine the optimal data quantity and type needed, avoiding unnecessary data transmission demands

Inventive Principle:

Principle #10Preliminary action

AI summary

Aspects presented herein may enable a user equipment (UE) to dynamically adjust map data to be downloaded from a server based on currently available information and the specifications/demands of advanced driver assistance systems (ADAS) and/or autonomous driving (AD) features, thereby reducing/optimizing the overall map data transferred over-the-air. In one aspect, a UE identifies whether at least one vehicle feature meets a set of thresholds based on at least one of stored map data, sensor information, or vehicle-to-everything (V2X) information. The UE transmits, to a server based on an identification of whether the at least one vehicle feature meets the set of thresholds, a request for map data. The UE receives, from the server based on the request, the requested map data.
