Autonomous Vehicle Trajectory Shifting for Emergency Lane Formation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing motor vehicles struggle to form emergency lanes effectively during autonomous or partially autonomous driving operations, leading to potential blocking of emergency lanes and delays for emergency vehicles.
Innovation Solution
A method that shifts the driving trajectory to the edge of the lane based on lane, speed, and traffic information, and stops the vehicle before bottlenecks or intersections when necessary, using sensors and communication systems to anticipate and prevent lane blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the vehicle drives centrally in the lane during autonomous operation, then the driving trajectory is stable and predictable, but the emergency lane may be unintentionally blocked
Solution Approach 1:
The system performs preliminary detection of emergency vehicles using sensors and communication systems before the vehicle reaches the critical section. The driving trajectory is shifted to the edge of the lane in advance, before the emergency vehicle arrives, ensuring the emergency lane is already formed when needed without requiring last-minute manual intervention.
Solution Approach 2:
The system continuously monitors the environment using sensors (cameras, radar, lidar) and communication systems to detect emergency vehicles. Based on this feedback, the control device automatically adjusts the driving trajectory to form emergency lanes, creating a closed-loop control system that responds to real-time conditions.
2Adaptability or versatility
If the vehicle shifts driving trajectory to form emergency lanes, then emergency vehicle passage is enabled, but the normal driving path may be affected
Solution Approach 1:
The system shifts the driving trajectory to the edge of the lane in advance, before the emergency vehicle arrives. This preliminary action ensures that the vehicle is already positioned to maintain an open emergency lane without needing to slow down or stop when the emergency vehicle approaches, thus minimizing impact on driving speed.
Solution Approach 2:
The driving trajectory is dynamically adjusted based on real-time detection of emergency vehicles. The control device continuously modifies the lane position to maintain the emergency lane while keeping the vehicle on a safe and efficient path, optimizing both emergency response and normal driving performance.
3Measurement precision
If manual intervention is required to form emergency lanes, then precise control is achieved, but response time is increased
Solution Approach 1:
The system performs emergency lane formation autonomously without requiring driver intervention. The control device automatically detects emergency vehicles using sensors and communication systems, determines the appropriate trajectory adjustment, and executes the lane formation maneuver, eliminating the time delay associated with manual detection and response.
Solution Approach 2:
The system uses continuous feedback from sensors and communication systems to monitor for emergency vehicles. When an emergency vehicle is detected, the feedback loop triggers automatic trajectory adjustment to form the emergency lane, ensuring both precision and rapid response without manual intervention.

AI summary
An approach for operating a motor vehicle that is designed for an autonomous and/or partially autonomous driving operation in which the motor vehicle is moved along a predetermined driving trajectory. During the autonomous or partially autonomous driving operation, a driving trajectory running centrally or substantially centrally along the lane traveled is shifted to the edge of the lane on the basis of lane information describing the lane currently traveled by the motor vehicle, and on the basis of speed information describing a current speed of the motor vehicle, and on the basis of at least one piece of traffic information describing a current traffic volume in the surroundings of the motor vehicle. Alternatively, or in addition, the motor vehicle is stopped before a bottleneck or an intersection is entered on the basis of road-course information describing the bottleneck or the intersection along the road course to be traveled, and additionally on the basis of emergency vehicle information describing the presence of an emergency vehicle in the surroundings of the motor vehicle, and/or on the basis of accident information describing an accident along the road course to be traveled.
