Solution Overview

Problem

Current navigation systems for road vehicles often fail to provide a comprehensive view of both the immediate environment and the wider route, making it difficult for drivers to anticipate upcoming maneuvers and understand the general situation, as they typically present either purely local or global information, but not both simultaneously.

Innovation Solution

A method and device that dynamically switch between regional and local display modes based on the vehicle's position relative to the next instruction point, presenting the active route portion and the upcoming adjacent portion, with the regional mode showing a larger geographical area and the local mode providing a detailed schematic representation of the next maneuver.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the navigation system presents purely local information (current position and immediate environment), then the driver can locate himself in the immediate environment, but the driver lacks knowledge of the wider route and upcoming maneuvers

Engineering Contradiction:
Improvelocal position accuracyVSAvoidwider route information
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent segments the route information into multiple display modes: local mode showing immediate environment and regional mode showing wider route context. The system divides the information presentation into distinct segments that can be selectively activated based on the vehicle's position relative to instruction points, allowing comprehensive information delivery without overwhelming the driver at once

Inventive Principle:
Principle #1Segmentation

2Loss of information

If the navigation system presents global route information (entire route overview), then the driver can understand the general situation, but the driver lacks detailed information on the immediate environment and current position

Engineering Contradiction:
Improveglobal route informationVSAvoidlocal position accuracy
Core Design Contradiction:
Loss of informationVSMeasurement precision

Solution Approach 1:

The patent implements dynamic switching between display modes based on the vehicle's real-time position relative to instruction points. The system automatically transitions between local and regional modes as the vehicle approaches or moves away from maneuver points, ensuring the appropriate level of detail is always displayed without manual intervention

Inventive Principle:
Principle #15Dynamics

3Ease of operation

If the navigation system provides detailed schematic representation of the next instruction point, then the driver can understand the maneuver to be performed, but the driver loses context of the current position and surrounding geographical elements

Engineering Contradiction:
Improvemaneuver understandingVSAvoidgeographical context
Core Design Contradiction:
Ease of operationVSLoss of information

Solution Approach 1:

The patent applies local quality by providing different levels of information detail in different display modes. The local mode offers detailed schematic representation of upcoming maneuvers with high informational density, while the regional mode provides broader geographical context. Each mode optimizes information quality for its specific purpose without compromising the other

Inventive Principle:
Principle #3Local quality

AI summary

Method of guiding a road vehicle, making it possible to represent on a display means at least one active portion of route, as well as the real-time position of said vehicle either according to a regional mode R, or according to a local mode L, the regional mode consisting of a representation of a geographical zone comprising in particular the road segments corresponding to at least one portion of the route to be performed including the active portion of the route and a buffer zone, the segments corresponding to those of the route to be performed being highlighted; the local mode comprising on the one hand, for a first portion of the display device, a partial representation (11) of a route corresponding to the active portion (10) of the route and at least the forthcoming adjacent portion, and on the other hand, on a second portion of the display device, a detailed schematic representation (20) of the next instruction point P1.
