Emergency Stop Assistance with Passenger Release for Obstructed Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing emergency stop assistance systems face limitations in safely executing emergency stopping maneuvers due to environmental sensor constraints, particularly when the front view is obstructed, leading to unsafe or unexecutable lane changes.
Innovation Solution
A method and system that involves driver monitoring to detect unfitness, environment sensing to assess safety, and passenger interaction to confirm or adapt emergency stopping maneuvers, ensuring safe vehicle control even with obstructed views.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If the front camera is mounted in the middle close to the interior mirror to monitor the vehicle's environment, then the driver monitoring function is improved, but the view of neighboring lanes is blocked particularly when a large vehicle or truck is driving ahead
Solution Approach 1:
The system transitions from relying solely on a single front camera's two-dimensional view to incorporating data from multiple sensors including rear radars and additional cameras positioned at different locations. This multi-dimensional sensing approach allows the system to reconstruct environmental information even when the front camera's view is blocked by large vehicles ahead.
2Reliability
If the environment sensors are used to monitor the vehicle's environment for safe lane change, then the safety of emergency stopping maneuver is improved, but the system release is not granted when the front view is limited due to external circumstances
Solution Approach 1:
The system merges data from multiple sensor sources including front cameras, rear radars, and additional environmental sensors to create a comprehensive situational awareness. This fusion of sensor data allows the system to grant release for emergency stopping maneuvers even when individual sensors like the front camera have limited views due to external circumstances such as slow traffic or large vehicles ahead.
Data Source
AI summary
A method for performing a safe emergency stopping maneuver is provided. The method comprises: detecting driver status data; initializing an emergency stop assistance system, wherein the emergency stop assistance system determines a stopping position for the emergency stop of the vehicle and at least one planned emergency stopping maneuver; detecting environment data, wherein the environment data is characteristic of an environment of the vehicle; evaluating the environment data and generating a system release variable to release the planned emergency stopping maneuver; depending on the generated system release variable, triggering a request for release of the planned emergency stopping maneuver by another passenger of the vehicle and detecting a special release variable depending on input by the other passenger; performing an adapted emergency stopping maneuver on the basis of the system release variable, the special release variable and the planned emergency stopping maneuver.
