Opposite Lane Crossing Control for Large Vehicles
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large vehicles, such as trucks and buses, face challenges when navigating tight bends, as they often need to cross into the opposite lane, potentially causing gridlock at blind sections, especially in heavy traffic conditions, due to the inability to assess if the opposite lane is clear.
Innovation Solution
A method and control device that utilize a surroundings sensor system to detect road conditions and traffic, allowing for controlled trajectory planning, including determining a stop position before entering a blind section to ensure the opposite lane is clear, and using communication links or visual signals to manage oncoming traffic.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If large vehicles cut across the opposite lane to navigate tight bends, then the vehicle can complete the maneuver, but gridlock may occur at blind sections due to inability to assess if the opposite lane is clear
Solution Approach 1:
The control device determines a stop position before the blind section and checks whether the opposite lane can be driven on unobstructed before the vehicle actually enters it. This preliminary assessment prevents gridlock by ensuring the maneuver only proceeds when safe
Solution Approach 2:
The surroundings sensor system continuously provides measurement data about the opposite lane to the control device, which processes this information to determine whether it is safe to cut across. This feedback loop enables real-time decision-making about maneuver safety
2Reliability
If the vehicle stops or slows down at the stop position to check for oncoming road users, then safety is improved, but productivity decreases due to additional stopping time
Solution Approach 1:
The control device autonomously monitors the opposite lane using the surroundings sensor system and automatically determines whether it is safe to proceed. This self-service capability eliminates the need for manual checking while maintaining safety
Solution Approach 2:
The safety check is performed in advance at the stop position before the vehicle commits to the maneuver. This preliminary action allows the vehicle to proceed without additional stopping once safety is confirmed, minimizing travel time impact

AI summary
A method for driving a vehicle on an opposite lane in a controlled manner includes detecting, with a surroundings sensor system, surroundings of the vehicle and receiving, with a control device, measurement data of the surroundings sensor system. The method includes identifying at least one course of a road, and at least one course of at least one road user in the surroundings based on the received measurement data and planning a trajectory of the vehicle within the at least one course of a road. The method further includes identifying a section of the road wherein when driving on the section of road the opposite lane is cut across by the vehicle, and determining a first stop position for the vehicle prior to entering the identified section of road. The method then checks whether the opposite lane can be driven on in the identified section.
