Solution Overview

Problem

Existing methods for checking driving data recorded by a tachograph are cumbersome and time-consuming, particularly during traffic checks, as they require extensive operation and are not well-suited for quick and reliable monitoring.

Innovation Solution

Establishing an electromechanical coupling between a display device and a tachograph or card reader for automatic data transfer and comparison, allowing for non-quantitative violation reporting, which simplifies the process and reduces the need for complex user operation, enabling fast and reliable checks with optical or acoustic feedback.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If manual checking methods are used for tachograph data, then comprehensive evaluation is possible, but the checking process becomes time-consuming and operationally complex

Engineering Contradiction:

Improvecomprehensive evaluation capabilityVSAvoidchecking process duration

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The checking process is segmented into two stages: (1) automatic preliminary screening using the display device to identify violations, and (2) detailed manual evaluation only for vehicles with detected violations. This segmentation allows most vehicles to be processed quickly while maintaining comprehensive evaluation capability for problematic cases.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system performs preliminary automatic checking of tachograph data before manual evaluation. The display device automatically compares driving data with regulatory rules and pre-identifies violations, so that only vehicles requiring detailed review need manual intervention.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If detailed manual evaluation is performed on all vehicles, then accurate violation detection is achieved, but productivity decreases significantly

Engineering Contradiction:

Improveviolation detection accuracyVSAvoidnumber of checks per unit time

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The display device performs self-service by automatically downloading tachograph data, comparing it with regulatory rules, and generating violation reports without requiring manual intervention for each vehicle. This automation maintains reliable violation detection while dramatically increasing productivity.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The manual mechanical process of reviewing all tachograph data is replaced with an automated electronic system that downloads, processes, and evaluates driving data automatically, substituting human labor with electronic computation to improve both reliability and productivity.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If complex operation procedures are used for data checking, then thorough analysis is possible, but operational errors increase and user-friendliness decreases

Engineering Contradiction:

Improvedata analysis thoroughnessVSAvoiduser operation simplicity

Core Design Contradiction:

Measurement precisionVSEase of operation

Solution Approach 1:

The display device performs all complex data analysis operations automatically without requiring user intervention. The system downloads data, evaluates it against rules, and presents results autonomously, eliminating the need for users to perform complex manual operations while maintaining thorough analysis.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The complex evaluation logic and rule-comparison algorithms are extracted from the user's task and embedded within the display device's automated system. Users only need to interpret simple violation reports rather than perform complex manual analysis.

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

The invention relates to a simple and fast method for displaying a deviation of driving data of a motor vehicle recorded by means of a tachograph from at least one predetermined rule by means of a display device independent of the tachograph, wherein the display device is connected to a tachograph data memory of the tachograph containing the driving data by means of a detachable electromechanical coupling of the display device either to the tachograph or to a card reader connectable to the tachograph data memory (A),After connection, at least one subset of the driving data to be examined is automatically loaded from the tachograph data memory into a device data memory of the display unit (C) and automatically compared by a device microprocessor of the display unit with the at least one rule (E), and wherein, if (j) a deviation of the loaded driving data subset from the rule exists, the existence of the deviation is automatically and non-quantitatively transmitted to a user of the display unit as a violation message by a display unit of the display unit (H). The invention also relates to a system for carrying out the corresponding procedure.
