Tachograph Remote Data Download via Authentication Token

Solution Overview

Problem

Current tachograph data download processes are time-consuming and costly, requiring direct company card authentication and limited by the need for physical presence, leading to inefficiencies and increased costs due to the need for multiple vehicle visits and GSM data transmission.

Innovation Solution

A user-friendly interface for tachographs that enables remote authentication and data transmission using the Remote Download Protocol, allowing for authentication via external card readers and GSM, with a 24-hour activation window for data download, eliminating the need for continuous card presence and reducing costs.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If direct data download with company card authentication is used, then data security is ensured, but download time increases and productivity decreases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary authentication actions by storing authentication tokens and establishing pre-authorized sessions. The tachograph pre-processes authentication requests and stores validation data, allowing subsequent data downloads to proceed without requiring the physical company card to be present during the actual download operation.

Inventive Principle:
Principle #10Preliminary action

2Reliability

If company card must remain in tachograph during download, then authentication security is maintained, but time consumption increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The system creates a digital copy or representation of the authentication credentials in the form of stored authentication tokens and session data. This digital copy allows the tachograph to verify download requests without requiring the physical company card to be present, thereby maintaining security while eliminating the time loss associated with card presence requirements.

Inventive Principle:
Principle #26Copying

3Loss of time

If remote download via GSM connection is used, then time consumption is reduced, but direct data transmission capability is lost

Engineering Contradiction:
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The tachograph is equipped with a universal interface that can handle multiple data transmission modes through a single standardized connection. The front interface supports both direct data downloads and remote query protocols, allowing the device to function as both a local data storage unit and a remotely accessible data source without requiring separate specialized hardware for each function.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Ease of operation

If standardized remote download protocol is implemented, then ease of operation improves, but additional data transmission costs arise

Engineering Contradiction:
Core Design Contradiction:
Ease of operationVSLoss of energy

Solution Approach 1:

The system dynamically selects between direct download and remote query modes based on operational conditions. The tachograph can switch between maintaining a local data copy for direct access and enabling remote protocol access depending on whether the vehicle is available, thereby optimizing the balance between operational convenience and cost efficiency.

Inventive Principle:
Principle #15Dynamics

AI summary

A tachograph (2) is proposed which stores driver-related and/or vehicle-related data (D) in digital form in an internal memory and has an interface for transmitting the data (D) to external devices (3), in which the interface is an interface (8) which is configured in a freely accessible fashion on the front panel (2) of the tachograph (2) and which is configured for the transmission of authentication data (A) and for the transmission of data (D) independently thereof. Likewise, an arrangement which is equipped with said tachograph (2) and a method which is carried out with said tachograph (2) for the purposes of transmitting data, in particular for downloading data by remote data interrogation are proposed. The interface (8) is preferred for the transmission of authentication data (A) and of driver-related and/or vehicle-related data (D) in accordance with a standardized remote data interrogation protocol, in particular what is referred to as the remote download protocol (RDP), as a result of which the corresponding functionalities can be made easily and directly accessible in a user-friendly fashion via the interface on the front side of the tachograph device. As a result, for example the company card (32) can also be removed after the authentication, and the data download which is time-consuming per se can be carried out without the card. The card (32) can therefore still be used for a further download in another vehicle while the download is running.
