Commercial Vehicle Overtaking Coordination System
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Overtaking maneuvers between heavy commercial vehicles on freeways or multi-lane roads often require lengthy periods due to low speed differentials, impeding following traffic.
Innovation Solution
A communication system with transceivers in each vehicle allows for data exchange and evaluation of overtaking processes, incentivizing the lead vehicle to reduce speed through reward offers, and assessing cooperation based on driving dynamics, thereby shortening overtaking times.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the lead vehicle maintains its speed during overtaking, then the overtaking safety is improved, but the overtaking time increases significantly
Solution Approach 1:
The system performs preliminary communication and negotiation between drivers before the overtaking maneuver begins. The lead vehicle is informed of the overtaking intention in advance, and both drivers agree on speed adjustment parameters before the maneuver starts, allowing safe and coordinated overtaking execution
Solution Approach 2:
The system continuously monitors overtaking progress and provides feedback to both drivers through the communication system. Speed adjustments are made based on real-time feedback about relative position and speed differential, allowing dynamic optimization of the overtaking maneuver while maintaining safety
2Loss of time
If the lead vehicle reduces speed to facilitate overtaking, then the overtaking time is shortened, but the lead vehicle's productivity decreases
Solution Approach 1:
The system implements dynamic speed adjustment where the lead vehicle's speed is temporarily reduced only during the necessary overtaking period. The speed reduction is optimized to be just enough to allow safe overtaking, and the vehicle returns to its original speed immediately after the maneuver completes, minimizing productivity loss
Solution Approach 2:
The communication system allows negotiation of specific speed adjustment parameters between drivers. The lead vehicle driver can propose speed reduction values that minimize impact on their productivity while still enabling the overtaking maneuver, and these parameters are adjusted based on vehicle type, load, and road conditions
3Loss of time
If communication systems are installed in commercial vehicles, then cooperative overtaking can be achieved, but the device complexity increases
Solution Approach 1:
The communication system is designed to serve multiple functions beyond overtaking coordination, including general vehicle-to-vehicle communication, traffic information exchange, and cooperative driving scenarios. This multi-functionality justifies the investment in communication infrastructure by providing benefits across multiple operational contexts
Data Source
AI summary
The invention relates to a method and a communication system for shortening the overtaking time required between a first commercial vehicle (F1) driving ahead and a second commercial vehicle (F2) following behind, wherein overtaking data is transmitted by means of transmit-receiver devices (SE1, SE2) installed in both commercial vehicles (F1, F2) in connection with an intended and/or carried out overtaking process, and an evaluation of the overtaking process is carried out on the basis of the overtaking data after completion of an overtaking process.
