Solution Overview

Problem

Existing systems for controlling road vehicle entry into controlled sections, such as one-way streets and weight-restricted areas, are not suitable for safety-related applications and lack effective mechanisms to prevent unauthorized access and manage traffic flow.

Innovation Solution

A method and system that utilize entry authorization tokens, managed by a control system and on-board vehicle systems, to securely permit or prohibit entry based on safety criteria, including direction of travel, token availability, and vehicle attributes, with features like encryption and return mechanisms to ensure secure and efficient traffic management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If known toll control systems are used, then toll collection is enabled, but safety-related applications such as one-way street control and weight restriction monitoring are not suitable

Engineering Contradiction:
Improveapplication scopeVSAvoidsafety assurance
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The system uses a universal entry authorization token mechanism that can be applied to multiple different control scenarios including toll collection, one-way street control, weight restriction monitoring, and other safety-related applications. The token system serves as a multi-functional control mechanism that adapts to various road section requirements through configurable control criteria.

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

2Reliability

If manual control methods are used for road entry, then system complexity is low, but security against manipulations by road vehicle users is insufficient

Engineering Contradiction:
ImprovesecurityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system replaces manual control mechanisms with an automated electronic token-based control system. The control system automatically evaluates entry requests against stored control criteria and issues or denies tokens without human intervention, thereby enhancing security while managing complexity through automation.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The on-board system in the road vehicle automatically generates the entry permission signal based on the received entry authorization token, and the control system automatically evaluates entry requests and manages token issuance. This self-service automation reduces the need for manual intervention and enhances security.

Inventive Principle:
Principle #25Self-service

3Productivity

If entry authorization tokens are issued without limits, then traffic flow is maximized, but control over traffic density and admissibility requirements is lost

Engineering Contradiction:
Improvetraffic flowVSAvoidtraffic control capability
Core Design Contradiction:
ProductivityVSAdaptability or versatility

Solution Approach 1:

The system dynamically adjusts token issuance based on real-time evaluation of control criteria including traffic density, road section capacity, and vehicle attributes. The control system can adaptively control the number of tokens issued to maintain optimal traffic flow while ensuring admissibility requirements are met, rather than using fixed unlimited or rigid limited issuance.

Inventive Principle:
Principle #15Dynamics

4Ease of operation

If entry authorization tokens are not returned after use, then system operation is simple, but control over token inventory and continued traffic management is compromised

Engineering Contradiction:
Improveoperation simplicityVSAvoidtraffic management efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The system implements a feedback mechanism where road vehicles automatically return entry authorization tokens to the control system after using them to enter a controlled road section. This feedback loop enables the control system to track token usage, manage inventory, and continuously adjust traffic control decisions based on current road section occupancy and traffic conditions.

Inventive Principle:
Principle #23Feedback

AI summary

The invention relates to a method for automatically controlling the entry of a road vehicle into a road section controlled by a control system, comprising the following steps: a) before entering the controlled road section, an entry authorization token is requested from the control system by a vehicle-side system of the road vehicle; b) upon receiving an entry authorization token request, the control system checks whether issuing an entry authorization token to the requesting road vehicle is permissible; c) if permissible, the control system transmits the requested entry authorization token to the requesting road vehicle; d) at the latest upon entry into the controlled road section, the vehicle-side system generates an entry authorization signal if the requested entry authorization token has been received from the control system, and an entry prohibition signal if the entry authorization token has not been received.e) The generated entry permit or entry prohibition signal is further used in the road vehicle to generate a warning message and/or to carry out automatic control and/or regulation measures. The invention further relates to a control system for monitoring a controlled road section, a vehicle-side system, and a computer program.
