Solution Overview

Problem

Existing methods for establishing communication connections between motor vehicles in close proximity lack the ability to selectively connect with specific vehicles without intermediate nodes, limiting the purposeful establishment of direct communication links.

Innovation Solution

A method and apparatus that enable a motor vehicle to receive configuration data directly from another vehicle, determine its relative position using localization units and environment sensors, and establish a direct communication connection without intermediate stations, allowing users to select and communicate with nearby vehicles through a virtual display and input device.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If radio devices are used to send broadcast messages to all vehicles in vicinity, then communication coverage is improved, but ability to establish selective direct communication connection deteriorates

Engineering Contradiction:

Improvecommunication coverage areaVSAvoidselective communication partner selection

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The system segments the communication approach into two distinct phases: first using broadcast messages to discover available vehicles in the vicinity, then establishing selective direct communication connections with chosen partners. This segmentation allows the system to leverage broadcast for coverage while enabling targeted direct connections for selective communication.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses broadcast messages as an intermediary mechanism to facilitate the establishment of direct communication connections. The broadcast message serves as a discovery phase that enables vehicles to identify potential communication partners, after which a direct connection is established without requiring further intermediary involvement.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If telephone number exchange is required to establish communication connection, then communication security is improved, but ease of operation deteriorates

Engineering Contradiction:

Improvecommunication connection securityVSAvoidcommunication establishment convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system enables vehicles to self-identify and present their communication capabilities through automatically transmitted configuration data in broadcast messages. Other vehicles can directly select and establish connections based on this self-presented information, eliminating the need for manual telephone number exchange while maintaining security through structured data transmission.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary action by having vehicles automatically transmit their configuration data and communication readiness status before any actual communication connection is established. This preliminary information exchange enables direct selection and connection establishment without requiring subsequent telephone number verification steps.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If configuration data are transmitted directly without intermediate nodes, then communication efficiency is improved, but communication range deteriorates

Engineering Contradiction:

Improvecommunication establishment speedVSAvoidcommunication connection range

Core Design Contradiction:

ProductivityVSLength of stationary object

Solution Approach 1:

The system uses periodic broadcast messages to extend the effective communication range. Vehicles transmit their configuration data periodically through broadcast, allowing other vehicles to discover and select them even at greater distances. Once selected, the direct communication connection is established efficiently without intermediate nodes, combining the benefits of extended range with high communication speed.

Inventive Principle:

Principle #19Periodic action

AI summary

A communication link is established from a motor vehicle to an other vehicle in the vicinity of the motor vehicle by receiving configuration data from the other vehicle, and determining a relative position of the other vehicle relative to the motor vehicle. A virtual display, which indicates the other vehicle as a possible communication partner, is provided for a user of the motor vehicle by at least partially using the relative position of the other vehicle and the configuration data. A communication command is received from the user, by which the other vehicle is selected as the communication partner. A direct communication link is then established with the other vehicle having been selected as the communication partner.
