Solution Overview

Problem

Current automotive technologies face challenges in providing precise and efficient use of route profile data for vehicles, especially in varying road conditions, due to limitations in sensor systems and navigation data resolution, which affects vehicle stability and comfort.

Innovation Solution

A method and apparatus that process route profile data by acquiring and assigning first and second sets of data, where the first set is collected by a vehicle's sensor system and the second set is detailed and accurate, determining the degree of similarity to map local physical characteristics and influence the vehicle's conditions, enabling precise regulation and control systems.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If detailed and accurate second set of route profile data is used, then manufacturing precision and measurement precision are improved, but device complexity and data processing requirements increase

Engineering Contradiction:
Improveroute profile data accuracyVSAvoiddata processing complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The route profile data is divided into two distinct sets: a first set collected by the vehicle's sensor apparatus and a second set obtained from external sources. This segmentation allows the system to leverage detailed external data while using locally collected data for verification and alignment, reducing the complexity of processing single massive datasets.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary processing step that determines the degree of similarity between the first and second sets of route profile data. This similarity assessment acts as a mediator that selectively integrates detailed external data with locally collected data, enabling high precision without directly processing all raw external data through the vehicle's systems.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If simple sensor collection method is used, then ease of operation is improved, but measurement precision deteriorates

Engineering Contradiction:
Improvedata collection simplicityVSAvoidroute profile data accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The patent merges two data collection approaches: simple local sensor collection (first set) and detailed external data acquisition (second set). By combining these methods and determining their degree of similarity, the system achieves both operational simplicity through local sensors and measurement precision through external detailed data without requiring complex integration.

Inventive Principle:
Principle #5Merging (Combining)

3Stability of the object's composition

If complex actuator system is used to compensate for route variations, then vehicle stability is improved, but weight and energy consumption increase

Engineering Contradiction:
Improvevehicle stabilityVSAvoidvehicle weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent applies preliminary action by determining the degree of similarity between route profile data sets in advance, before the vehicle encounters the actual route conditions. This allows the regulation and control systems to be pre-configured with accurate route information, enabling more efficient actuator operation and potentially reducing the complexity and energy requirements of the stabilization system.

Inventive Principle:
Principle #10Preliminary action

AI summary

Route profile data for a vehicle is processed by acquiring a first set of the route profile data for a predetermined route section of a route of the vehicle depending on data provided by a sensor of the vehicle or another vehicle, where the first set of the route profile data is representative of at least a first local physical road characteristic of the predetermined route section. A second set of the route profile data, which is at least partly related to the predetermined route section, is read, where the second set of the route profile data is representative of at least a second local physical road characteristic. A degree of similarity between the first set of the route profile data and the second set of the route profile data is determined. The second set of the route profile data is assigned, based on the determined degree of similarity, to at least one of conditions immediately surrounding the vehicle and a time-dependent mapping function of influences that the route has on the vehicle.
