Narrow Passage Assistant Trajectory Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems are inadequate in providing effective support for navigating motor vehicles through bottlenecks, as they fail to accurately determine collision-free trajectories and provide timely warnings or guidance to drivers.
Innovation Solution
A bottleneck assistant system that uses data from on-board sensors and external sources to determine collision-free trajectories, displaying a target driving path and providing visual warnings to the driver, and transmitting information to other vehicles to update maps and prevent false alarms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If driver assistance systems provide comprehensive bottleneck navigation support, then driver safety and collision avoidance improve, but system complexity and computational requirements increase
Solution Approach 1:
The system segments the bottleneck passage problem into discrete trajectory calculations and individual warning scenarios, processing each separately rather than as a monolithic complex problem
Solution Approach 2:
The system performs preliminary trajectory calculations and bottleneck assessments before the vehicle reaches the bottleneck, allowing the driver to be warned in advance and prepare accordingly, reducing the complexity of real-time decision-making
2Ease of operation
If the system provides detailed trajectory and warning information, then driver decision-making improves, but information processing time and computational load increase
Solution Approach 1:
The system calculates trajectories and assessments preliminarily before the vehicle reaches the bottleneck, so that when information is presented to the driver, it is already processed and ready for immediate decision-making
Solution Approach 2:
The system extracts only the critical bottleneck information and essential trajectory data needed for driver decision-making, rather than presenting all possible data, reducing processing time while maintaining ease of operation

AI summary
The invention relates to a method for operating a motor vehicle (1), comprising the following steps: checking, by means of a narrow passage assistant (2) of the motor vehicle on the basis of data characterizing dimensions of a narrow passage (7), whether at least one trajectory for collision-free driving through the narrow passage (7) by the motor vehicle (1) can be determined; if no trajectory for collision-free driving through the narrow passage (7) can be determined: outputting a warning message; if at least one trajectory for collision-free driving through the narrow passage (7) has been determined: signaling that travel through the narrow passage (7) is possible, a target driving path being displayed by means of a display device of the motor vehicle (1) in accordance with the determined trajectory, it being possible to drive through the narrow passage (7) without collision so long as the motor vehicle (1) drives within the target driving path. The invention further relates to a motor vehicle (1) having a narrow passage assistant (2).
