Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle guidance systems lack reliable and robust automated longitudinal guidance capabilities, particularly in urban areas where signaling units such as traffic lights and stop signs complicate the driving function, affecting safety, comfort, and availability.
Innovation Solution
A vehicle guidance system that integrates signaling unit data into its operation, using sensors and map data to determine the type, position, and state of signaling units, allowing for automated speed and distance control, and providing user interfaces for manual override, with modes for automatic and manual operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If automated longitudinal guidance is implemented at signaling units, then safety and comfort are improved, but system complexity increases
Solution Approach 1:
The system segments the automated guidance functionality into distinct operating modes (automatic mode and manual mode) that can be independently selected and configured. This allows the complex signaling unit response system to be divided into manageable operational states, reducing overall system complexity while maintaining safety improvements.
Solution Approach 2:
The system dynamically adapts its level of automation based on the selected operating mode and detected signaling unit conditions. The guidance system can switch between automatic intervention and manual control, allowing flexibility in complexity management while ensuring safety through appropriate automated responses to traffic signals.
2Reliability
If automated longitudinal guidance is implemented at signaling units, then comfort is improved, but device complexity increases
Solution Approach 1:
The device complexity is segmented through separate control pathways for automatic and manual modes. The comfort-improving automated responses to signaling units are implemented as distinct functional segments that can be activated or deactivated based on user preference, managing complexity while enhancing comfort.
Solution Approach 2:
In automatic mode, the system provides self-service by automatically detecting signaling units and executing appropriate longitudinal guidance actions without user intervention. This enhances comfort through automated comfort-oriented responses while the system manages its own complexity internally.
3Adaptability or versatility
If multiple operating modes are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The multiple operating modes are segmented into distinct, well-defined states (automatic mode and manual mode) with clear transition rules. This segmentation allows the system to provide adaptability through mode selection while managing complexity by maintaining clear boundaries and separate control logic for each mode.
Solution Approach 2:
The guidance system achieves multi-functionality by incorporating both automatic and manual operating modes within a single system framework. This universal design allows the same device to adapt to different user needs and driving situations without requiring separate systems, managing complexity through integrated multi-functional architecture.

AI summary
Described is a vehicle control system for providing a driving function for the automated longitudinal control of a vehicle at a signaling unit. The vehicle control system is configured to detect, during operation of the driving function, a first signaling unit located ahead of the vehicle in the direction of travel on a roadway on which the vehicle travels. The vehicle control system is additionally configured to ascertain one set driving mode of a plurality of different driving modes and to cause the vehicle to be automatedly longitudinally controlled according to the set driving mode when the vehicle approaches the first signaling unit.
